While we are walking in the street at night, we may see all kinds of billboard, the bright lamp boxes, the traffic lights, the route signs, so what is the common point among them? Yes, they mostly contain the LED techniques, they are the products of LED. Unconsciously, the LED products entered in our life, offered convenience to us, moreover, due to the emergence of LED fluorescent light the society we are in became more normalized, please image if the roads are without traffic lights and route signs. Now that the LED products possess the important position in our life, the LED tube suppliers must be more rigorous to the products.
On February 20, the eighth GZ international LED lighting fair opened at Pazhou exhibition center, which is known as the “vane” for LED industry development. As an industry leading enterprise, Spark takes part in the exhibition.
Spark booth is 90 square meters, double floor design, to show intelligent controlled LED Street lamp, high brightness LED tunnel light, LED High Bay lights, LED Traffic lights, LED tube light, dimmable LED panel light, LED down light and so on. Visitors come in an endless stream.

Thanks for our new and old customers’ support for Spark. We will always follow the “quality innovation honest service” business philosophy, to provide customers with high quality products and good service.
Look above information, we learned the reasons for LED tube lighting to capture the no small market share or to be an important part in our life is sufficient, but the sufficient reasons contain too much things, techniques, quality, advertising, trademark etc, for a manufactory, it’s hard to complete the “sufficient reasons” and achieve the final target, as it were, the most LED products that accepted by customers are thoroughly tempered. Thus, the LED exhibition in Guangzhou would draw so much attention, the influence of led tubes in market will be involved in the participation of every walk of life.
With more and more use of LED, especially billboard, lamp house etc. Of course, LED technology will be applied to the neon, comparing to the traditional neon, what merit does led tube light have? What merit dose LED tubes bring to the neon?
Tetra systems consist of a strip of rugged LED modules connected by flexible, heavy duty wire to each other and to a power supply (figure 1). In channel letter applications, sign manufacturers typically install these systems into aluminum letter shapes with translucent vinyl facings (figure 2).With the addition of white; GEL core now sells strips with a range of 10 LED colors. “A customer will typically match the color of LEDs and the color of the facing or other enclosure to meet their corporate branding requirements both at night when the sign is lit and also during the day,” said Mike DE Marco, Tetra product manager. Figure 3 shows an example of the Tetra product in use in channel letter signage.
GEL core’s white Tetra strip uses blue LED chips in combination with a proprietary GE phosphor. DE Marco says that the industry has had to wait a little longer for white due to technical developments that improved performance and reduced cost. Comparing to the LED tubes, the product has a color temperature around the value of 6500 K typical of white neon tubes with a phosphor coating, since it is easier for sign manufacturers to deal with colors similar to those currently available. Rugged design
One of the principle advantages of LEDs compared with neon is ruggedness and durability, and Tetra has been designed to enhance these characteristics. The Tetra system uses square Piranha LED packages that snap into rugged modules, creating the sign industry’s first patented LED design that does not use printed circuit boards. This eliminated the need for added electronic components such as resistors and capacitors. “We look at total potential failure points, and systems that eliminate PCBs and don’t have solder points are much less likely to fail in a demanding environment such as an outdoor sign,” explains DE Marco.
Thermal management is achieved via a patented design that uses the connection of the electrical wire to the module to provide a thermal interface, as opposed to using large heat sinks or circuit boards. “This design allows us to under drive the LEDs so there is less heat to dissipate, which also helps extend LED life,” says DE Marco. “The electrical and mechanical connection to the wires provides more than adequate heat sinking. “Longer runs Mandarin school shanghai
Tetra strips are packaged in reel form and can be cut to any desired length. GEL core also sells splice connectors that allow simple and rapid connection of supply wires to the Tetra strips. Addressing the need for longer runs in some applications, the new GE Tetra XL is capable of operating up to 160 feet of led tubes from a single 12 V power supply. “This has proved popular with installers and end-users, as it means there will be fewer building or wall penetrations, and installation can be quicker and easier,” says DE Marco. “The power supply can be remotely mounted up to 150 feet from the installation, and fewer power supplies can be used in some situations.”
The ability to drive long runs of LEDs is achieved using a 3-wire series-parallel connection system (figure 4). In the standard Tetra system the LEDs are all connected in parallel, and if one of the LEDs fails then the rest stay illuminated. In Tetra XL, groups of 3-5 LEDs are connected in series, and if any LED fails the whole series goes out. “This trade-off is necessary to achieve longer runs,” says DE Marco. “However, even losing a series of several LEDs would not be noticeable in many of the large signs used throughout North America, which often use several rows of LEDs.”The Tetra XL is particularly appropriate for use as a light engine in the GE Tetra BT, a border LED Tube system combining Tetra strips and power supplies with housings and lens reflectors. The product is used for exterior and interior border/contour lighting in applications such as petroleum stations and restaurants (figure 5).Mandarin school shanghai
Comparison with neon
As mentioned above, LED-based systems are much more robust than neon, not only when building the system but also during transportation and installation. Also, rather than replacing entire sections of neon signs, minor modifications can be made on site.
Critically, LED systems consume about 20% of the power of equivalent neon installations, which combined with long lifetime (Tetra products have a 5-year warranty) results in significant cost savings. LEDs are also low voltage, and do not contain hazardous substances such as mercury found in some neon tubes. Another disadvantage of neon is that light is given off in all directions and a large amount is wasted. Although LED systems like Tetra have a much lower lumen output, the light is all directed at the channel letter face rather than at the back or sides of the channel.
As with any LED system, cost is a major issue. “When end-users look at the complete installed cost, factors like lower labor costs during installation and a lack of breakages weigh heavily for LEDs,” says DE Marco. “The cost equation is strongest for warmer colors, and red LED-based systems are virtually on cost parity with neon.”
The neon light which apply LED axiom has more serviceability and durability than before, the system based on LED has more stability than neon. And above all, LED only use up 20% capacity, its long life and low cost are obviously embodied. As for cost, most led fluorescent replacement must care about this point. Happily, the cost of LED system only equate to the cost of ordinary neon. It means ordinary people can buy the one they like with little money, so if you need them, just to buy what you need.

The led fluorescent light installed in medical establishments bring comfort to patients
Posted on 2012 under 创业 | No CommentThe indoor lighting design is of critical importance to the general design of a building. How to optimize the indoor lighting environment? We should take the panel design into consideration, and the particular distribution of light, the light emitting diode, the optical film is noticeable. Now that it is about indoor lighting design, the LED Tube Lamps
has to be mentioned, many LED personnel launched the schemes that they would introduce the LED technology into office lighting design, for the purpose of building green lighting in office. Indeed, during the process of execution, LED fluorescent make great contribution to the office new environment.
GE Lighting Solutions of East Cleveland, OH, has introduced its first commercial product in the Lumination brand line. It is a recessed LED troffer offered in 600×600-cm (2×2 ft) and 300×1200-cm (1×4 ft) versions with a panel thickness of only 14 mm (0.5 in). Both sizes are offered in 3000K, 3500K and 4000K configurations.
The ceiling panel is designed for office, retail (Fig. 1), healthcare and education environments. The troffer is designed to compete with fluorescent fixtures and installs in common T-bar ceiling grids. A built-in dimmable driver, which brings the installed thickness to 64 mm (2.5 in), is designed to ease installation.
A critical aspect of the panel design is the technology used to achieve a particular distribution of light from the panel to the target area. Cree XP-G LEDs are mounted horizontally along the side of the panel while an optical film that incorporates high-efficiency microprismatic materials optimizes the photometric distribution. GE licensed this microprismatic material, called MicroLens, from Sunnyvale, CA-based Rambus. Using proprietary optical modeling software and design techniques, MicroLens optimizes the light distribution across an entire surface or focuses the light in specific locations. Luminous output is 3550 lm at 50W and 4000K or 3220 lm at 3000K and 50W. CRI is 80.
When illuminated, the Lumination led fluorescent replacement produces an even glow and complies with the required UGR 19 glare rating for office lighting. When the panel is off, it appears free of a light source, unlike fluorescent fixtures.
“The Lumination brand signals our arrival in LED fixture design and aspires to shape the future of indoor lighting,” says Steve Briggs, vice president of marketing and product management for GE Lighting Solutions. “Whether making a bold statement in your office, optimizing a selling environment to dazzle customers or creating a calming healthcare setting, these fixtures are unlike anything you’ve seen before.”
The projected life to 85 percent of initial lumens is 50,000 hours and the product is supplied with a 5-year warranty. DALI or 1-10V dimming is standard and the system is compatible with daylight harvesting control systems for additional energy savings.
GE provided an energy savings analysis comparison with various fluorescent fixtures (Fig. 2). The minimal energy savings is 11 percent annually relative to a four-lamp T5 fluorescent tube configuration. Estimated energy savings of 26 percent can be achieved relative to a two-lamp twin-tube fluorescent configuration.
GE Lighting Solutions has stated that it expects to introduce more than ten new luminaires in the next year and a half including including linear, suspended-fixture and surface-mounted troffers.

The light in healthcare environment seems more important than others, this is because the patient need nice and cozy lighting environment, maybe it belongs to the auxiliaries in hospitals, but its influence is no less important than medical treatment, if the moderate and fit light revolved around the patient, they would feel comfortable, otherwise, the dazzling light make people depressed. Of course, we need some technologies to meet such these requirements of light, thanks to the led, we make it possible. The LED fluorescent lights installed in hospital not only bring gentle light, but also cut the most energy consumption for hospitals, its importance is evident.
Jack Curran of LED T8 gave an engaging and educational presentation and his perspective on “LED Performance Guidelines: Good; Bad and How to Tell the Difference” to over 200 attendees.
Curran said, “If there was one general takeaway for everyone, it would be ‘Don’t believe what you read and only trust third-party information,” adding, “Ensure that testing is coming from and independent accredited lab, not (for example) Jack Curran’s Taco Emporium and Testing Lab!” Later if his presentation, Curran detailed and discussed controversial LED applications such as the infamous T8 fluorescent tube replacement which caused for a provocative discussion with the attendees. Curran will give another seminar entitled “Smoke, Mirrors, & LEDs” on Wednesday,， a theme about LED tubes T8 on May 12 at 4:30. According to the DOE’s Jim Broderick, Curran will be giving similar talks on behalf of DOE at a number of other conferences throughout the year. Roddick said “Curran’s seminar and DOE’s tutorials should give you a leg up as you try to make your way through the bewildering array of SSL products at Light fair. But as you walk the floor, you’ll do well to have your hype-detectors out and to ask a lot of tough questions.”
As outdoor lighting plays a major role on campus at colleges and universities, Moji Nava of the University of Michigan, presented “Outdoor Lighting Design Challenges for a University Campus.” Nava explained how the eye functions and reacts to light, as well as how perceptions shape lighting. He also explained how lighting can affect the perception of safety and security. An interesting part of his presentation was the summarizing of the proposed models and systems of masonic photometry. In late May, the DOE will be holding a workshop in Portland, entitled “SSL in Higher Education Facilities,” especially for colleges and universities noting that colleges and universities are complex facilities that use almost every type of lamp and luminaire, encompassing a wide range of applications and environments, such as classrooms, offices, residences, museums, theatres, chapels, libraries, labs, parking lots, garages and outdoor lighting, to name a few. Their facilities need to communicate an image and philosophy, while being functional, maintainable, and sustainable. At Monday’s luncheon, keynote presenter Steve Jones of McGraw-Hill Construction spoke about the construction industry and modeling technologies. Mandarin school shanghai Jones detailed the Model Progression Spec process and when referencing lighting, he indicated that lighting must be designed and modeled accurately in the initial stage of a project in order to work within this model.
Jean song Jiao of Orem Opt Semiconductors Inc. provided an update on LED & Solid State Lighting Standardization, presenting a comprehensive overview of the standardization process and new standards for LED. Jiao highlighted standards in both performance and safety. He explained that some standards are regional and sometimes culturally driven, but he takes the position that global standardization is a better direction and is more practical. Jiao also give a perspective on Energy Star specifications. Earlier today, the US EPA announced the release of Draft 1 Version 1.0 of the Energy Star Program Requirements for Luminaries. This “hybrid, technology neutral” specification is intended to replace the existing Residential Light Fixtures (V4.2) and Solid State Lighting Luminaires (V1.1) specifications. As today’s release was unexpected but long anticipated, Jiao meticulously updated his presentation, only hours in advance, to reflect these changes and give attendees accurate and up to date information, LED T8 tube lighting should be better.
Jiao explained that the new specifications differentiate directional and non-directional luminaire, rather than classifying them as decorative or functional. He rationalized the EPA’s direction, as being “user oriented versus producer oriented,” as the intention of Energy Star is consumer directed and focused. The most serious concern in this revised direction is that some manufacturers who have previously qualified or who are in the process of doing so, after significant R&D and manufacturing investments, may have to “go back to the drawing board” and start over again.
Events on Tuesday
Don’t miss today’s luncheon keynote presentation by the DOE’s Jim Broderick “Solid-State Lighting: Preparing for the Opportunity” at 12:15 pm, when he will explain the caveats and give compelling reasons why these questions are necessary, arming the attendees with an arsenal of questions to ask when they walk the trade show floor. As LED and OLED lighting are heading your way, Broderick says, “Chance favors the prepared mind.” The DOE will also be running a training schedule with free tutorial sessions in their booth (#2121) during show hours from Wednesday to Friday. You can find the schedule in tomorrow’s issue of The Daily Light fair.
Today will be another busy day of education from the Light fair Institute. LED Luminaire Design, a 1-day course begins at 9:00 am. The course offers a full day of presentations from and a panel discussion with 4 industry professionals, moderated by Mark McLean from Cree. The panel will discuss fundamental design considerations necessary to establish a framework for successful LED fixture design, including the integration of four engineering disciplines: optical design, electrical design, thermal management and mechanical design. Panelists will explain how optimizing performance in any single area can mean compromising performance in the others. Today is the day for questions and this course is no exception as attendees will learn the “12 Questions your LED Fixture Manufacturer must answer”.
This proseminar held by DOE lasted so long time , there are bound the be some divergence during the period of discussion , such as new standard of LED and worldwide standardization , their common aim is to make the LED technology more standardize , more sane while it is faced to the customers. They mentioned many new concept and new idea, not only proposed the general plan of the university lighting condition, but also proposed some solutions about the issues of LED. As for LED T8 tube lighting, it is very important in the LED market, but whether it should take replacement of all the non-led lighting is a question. So maybe sometimes we may look forward on the good light condition.

The discussion of LED T8 makes us think about the lighting condition
Posted on 2012 under 创业 | No CommentDOE held a proseminar in various high-schools and universities, discussed the condition of lighting in universities, and mentioned the concept of ““Outdoor Lighting Design Challenges for a University campus This delivery stood a very broad category , mainly involved the lighting condition of university education, as in class , museum , theatre , church , library etc. , in short ,except the campus ,the other public place , aiming to build a good environment to protect eyes. This proseminar was caused by the discussion of LED T8 which is about the T8 fluorescent tube replacement, it drew our attention on the issue of LED.

As for LED T8 tube lighting, it is very important in the LED market, but whether it should take replacement of all the non-led lighting is a question.
The household lighting is the wide spread adoption and energy efficient .When designed properly, an LED circuit will approach 80% efficiently, which means 80% of the electrical energy is converted to light energy. For comfortable viewing and brighter lighting, LED T8 provides a new sense of lighting experience. Though the present market for LED tubes T8 is geared mainly towards enthusiasts and early-adopters, the efficiency and cost effectiveness of LED T8 tube lighting
systems will drive demand for more affordable LED lights.
What are the advantages? Energy Savings
LED T8 uses approximately half the energy of a comparably rated fluorescent light based upon light output. Different brands and different manufacturers may deliver different energy consumption results. According to the U.S. Energy Information Administration, lighting accounted for approximately 26 percent of the energy used in an average home in 2005. Consumers who switch from their current lighting options to T8 LED bulbs could experience a total monthly energy consumption savings of more than 13 percent.
Nontoxic
Fluorescent light tubes, including compact fluorescent lights, are coated on the inside of the enclosed tube with a phosphorous material. The tube is filled with a small amount of mercury vapor at low pressure. When electricity is introduced, the mercury gas produces ultraviolet light. The ultraviolet light reacts with the phosphorous coating to produce white light that is useful for human environments. Fluorescent lighting is much more energy efficient than incandescent lighting, but the mercury contained in the fluorescent tube is a known toxin that can be released into the environment if the tube is broken. T8 LED bulbs do not contain mercury or any other toxic substance that can harm the environment.
Safety, Convenience, Longevity
Most of the energy required to power a conventional incandescent bulb is lost to heat. T8 LEDs produce light without producing heat, making them much more efficient and safer, because there is no risk of burns. T8 LEDs utilize the same structure as a T8 fluorescent tube, and can be used in the same fixtures, although T8 LEDs have no need for a ballast like a conventional fluorescent tube. T8 LEDs have expected useful lifespans of up to 80,000 hours, approximately five times greater than conventional fluorescent tubes, according to LED Liquidators.
Why LED T8 is better?
LED lights provide a color that is crisp and bright like no other form of artificial light has been able to accomplish. Anytime someone is looking at a gorgeous array of lights coming from an outdoor fountain that changes colors, that person is probably looking at a series of LED lights with a motion control device attached to it.
The use of LED lights has become more popular in the past decade and many people are opting for these elegant lights simply because of their appearance. But often sheer beauty isn’t enough to bring someone around to a new technology.
So, why are LED lights better than their current lighting and what could make them change? Because LED lights do not draw energy in the same way that incandescent lights do, they cost about 80% less to operate. LED lights are even more energy efficient than CFL bulbs which contain toxic mercury. This means that by switching all of the light bulbs in a home over to LED lights, a person will realize a sizable decrease on the cost of lighting his/her home. In some cases, people have reported as much a 50% reduced electric bill as a result of using LED lights instead of other lighting sources. The third most common reason why LED lights are better is because they are so durable and long lasting.
Most light bulbs have a life expectancy that is rated at approximately 2000 hours of usage. In many cases those light bulbs will fail well before those 2000 hours have passed. This is mostly due to the fact that the filaments cannot withstand electric fluctuations, such as those which occur when the light switch is flipped. LED lights do not need time to cycle or warm up, they light instantly, for this reason, and the fact that they do not get hot, they are rated at about 100,000. LED lights are also much more durable than other light bulbs and are nowhere near as breakable.
LED T8 light is definitely the wave of the future, and is changing the way the world is seeing things, literally. It will be interesting to see what changes will bring with more residential applications of LED T8. A little change makes a better life. With so many advantages over conventional ones, its competitive power in the market will highlights our research toward a green future, little harmful to our environment. With more people choose LED tubes T8, a new and better green circle will conformed. The question shouldn’t be “Why are LED lights better?” So if you have read the texts carefully, you will see the answers.
Make a comparison with traditional fluorescent tubes, and we will see LED fluorescent lamps are a great invention we ever had, much closer to our sustainable goal. There are many LED fluorescent light advantages for home and business use which makes it no surprise that so many people and businesses are now choosing LED fluorescent tubes option for their needs. Before we are going on, we had better know that LED fluorescent tubes and fluorescent tubes are completely different technologies. Why name the new type of lighting “LED fluorescent lamps”? That is because it reminds us of traditional fluorescent tubes, brings us back the old but good feeling, but it has avoided many of the disadvantages of traditional fluorescent tubes. What a marvelous idea! To give recognition where it’s due, fluorescent tubes are a great invention.
Introduction to LED Fluorescent
Light-emitting diodes (LEDs) are a technology that has advanced from use in numeric displays and indicator lights to a range of new and potential new applications, including exit signs, accent lights, task lights, traffic lights, signage, cove lighting, wall sconces, outdoor lighting and down lighting.
Fluorescent tube is the main lighting source for interior areas, like offices, schools, hospitals, stores, hotels, garages, supermarkets, warehouses and factories etc. LED fluorescent light offers benefits such as small size, long lamp life, low heat output, energy savings and durability. They also allow extraordinary design flexibility in color changing, dimming and distribution by combining these small units into desired shapes, colors, sizes and lumen packages.
Pros of LED Fluorescent Tubes
High Efficiency
One of the key advantages of LED-based lighting sources is high luminous efficacy. White LEDs quickly matched and overtook the efficacy of standard incandescent lighting systems.
It is obvious that only the light casted down are useful; but fluorescent tube outputs light into all directions (360 degree). The reflector on the fixture can direct some light to downside, but that is not enough. Test shows at least 50% light are wasted, that means a 4ft fluorescent tube produces 2500lm (approx), only 1250lm is used for lighting up working desk.
Durable
LED Fluorescent tubes are highly rugged. They feature no filament that can be damaged due to shock and vibrations.
LED Fluorescent tubes have no filaments or moving parts and can withstand shaking and vibrating without breaking. They do not use ballasts which can fail and become a fire hazard. LED Fluorescent tubes work well in hot or cold environments and can withstand moderate power surges. LED Fluorescent tubes are not bothered by frequent cycling on or off and can be left on for extended periods without generating much heat.
Minimum Heat
LED Fluorescent tubes generate very little heat, transferring power to light instead of heat. Heat from traditional lighting creates a higher load on air conditioning systems, adding to the energy inefficiencies of non-LED lighting.
Natural, eye-pleasing spectrum
White and soft white LED Fluorescent tubes produce a full-spectrum light closely resembling daylight, illuminating tasks and enhancing work, school, and retail environments. LED fluorescent light can provide exceptional directional lighting to enlighten a work area and create a bright, clear light for showcasing retail products.
Nontoxic
Fluorescent light tubes, including compact fluorescent lights, are coated on the inside of the enclosed tube with a phosphorous material. The tube is filled with a small amount of mercury vapor at low pressure. When electricity is introduced, the mercury gas produces ultraviolet light. The ultraviolet light reacts with the phosphorous coating to produce white light that is useful for human environments. Fluorescent lighting is much more energy efficient than incandescent lighting, but the mercury contained in the fluorescent tube is a known toxin that can be released into the environment if the tube is broken. T8 LED bulbs do not contain mercury or any other toxic substance that can harm the environment.
A Bright Scene for LED Fluorescent Tubes
LED fluorescent lamp is one of the lighting applications that require only a few lumens. In fact, installing LED’s now can cut energy costs by up to 90%. The advantages are obvious. We choose, as we live. To make a better world, it is considered everyone in the world, especially we with environment consciousness, should make the wise choice, in responsible for the ecological environment and for our next generations. LED lighting technology has been researched and developed for the past two decades and we are beginning to see practical applications from this work. And we will benefit more from it (LED fluorescent lamps) in the future!
大学生创业要学会掌握时机，迅速出击、一击必胜 大学生创业不仅仅是对于大学生能力的考验，更是对于他们对时机把握度考验。粉刷匠墙绘工作室、“数码享购”网店、笨笨熊手工创意馆、歪歪时尚饰品店、张氏美容生活馆……这里的“老板”都是在校大学生，办理了工商执照、税务登记，要租赁店面、招聘职员。这里是全省首家由政府和高校共同建设的大学生创业孵化中心——宜春学院大学生创业孵化中心。 以创业促就业，是拓展大学生就业空间的重要途径。2009年8月，顺应在校大学生越来越强的创业意识，宜春学院决定拿出大学生活动中心二楼18间共600多平方米的校园店面，设立大学生创业孵化中心，让在校大学生来开店、办公司，并组织专家团为入孵大学生提供创业指导、创业孵化培训和创业市场开拓等服务。 创业孵化受到了大学生们的热捧，首期就有100多名在校大学生提交了创业计划书，申请入孵。他们高兴地说，他们热衷在校创业，不图赚多少钱，而在于他们有想法，敢于试，孵化中心为他们施展才干、实现梦想提供了便利平台。 宜春学院招生就业处副处长刘新坤告诉记者，学校在创办孵化中心之初，一直在思考，比较谨慎。他说：“只有学有余力、创业愿望强烈、有较好创业项目的本科大三、专科大二以上学生，并经专家评审、辅导和家长同意，项目才能入孵，由此还可解决创业大学生的工作与学习之间的矛盾。” 2009年9月，本着“家长知情，学校认可，组织确认”的入孵原则，经专家委员会评审，“张氏美容生活馆”、“饰界之窗”、“广角影视传媒制作中心”等首批18个创业项目入孵；“我着我衣”格子铺、“青春苹果服务中心”等9个在校园内或校园周边的大学生创业项目也纳入孵化中心统一管理。创业孵化中心店面第一年免租金，水电费减半；第二年实行租金优惠；在校大学生创业享受毕业生创业同等优惠政策。 为破解在校大学生创业难以及实施担保贷款的瓶颈问题，宜春学院与宜春市劳动就业部门经多方调研，启动“宜春市大学生创业个人信用贷款评价体系”，明确了大学生创业信用贷款准入条件和个人信誉评价体系。目前，该校创业大学生已获首批大学生创业信用贷款11万元、担保贷款28万元，解决了创业启动资金问题，激发了大学生的创业热情。这样一来，大学生创业的势头才会越来越红火。
学会创新就学会了如何在大学生创业过程中掌握先机
创新任何时候都非常的重要，在大学生创业的过程中自然也不例外。一个简单的讯号就能让他捕捉到无限商机。凭借着鼓励和扶持更多大学生像自己一样创业的一种信念，他不断努力，不断创新，不断发展。他，就是吉林省拓普电脑科技有限责任公司总经理朱箭飞。这个大学毕业后就步入创业道路的年轻人对创业有着独到的见解。
1999年，朱箭飞大学毕业后并没有像其他同学一样找工作，而是成立了一家电脑科技公司。在一次为西民主小学校施工计算机机房的过程中，多次响起的传统上下课电铃声音让他觉得非常刺耳，于是用音乐铃声代替这种电铃声的想法油然而生。敢想还要敢干，于是朱箭飞与朋友一起积极寻找解决问题的办法。为更好实现自己的这一计划，他多次与朋友到北京及南方的厂家和中小学参观考察。
“一个企业的生命力离不开科技创新。”朱箭飞说，他是从事高科技行业的，就要不断通过科技创新为公司注入活力。2005年，朱箭飞开始将经营项目投入到吉林省高校市场，相继引进投影机、外语语音室等高校教学产品。经过几年的努力，产品已经在吉林省80%以上的高校得到了推广与应用。
2009年，朱箭飞组织公司的技术人员整合了高校精品课录播系统和外语语言学习平台。录播系统采用先进的图像定位技术，能够自动实时地将教师教学讲课的视频、音频、板书、计算机屏幕画面、多媒体课件及学生问答视频记录变为媒体文件，形成单画面电影模式或多画面资源模式，将其上传到校园网服务器，作为精品课程或网络课程在校园网上实现远程互动教学功能，可作为网上实时直播、点播的学习资源，全真再现课堂教学的全过程。
外语语言学习平台是一个建立在校园网上虚拟的外语学院，充分满足教师备课、课堂教学、自主学习、网络作业、无纸化考试及专业化口语考试的要求，实现对教、学、考的有效控制，使管理和评估更加便捷有效。这两项产品整合到一起，实现了一种全新的教学模式。随着公司的不断发展，朱箭飞的公司由最初4个人发展到现在的专兼职员工50余人，同时还先后为上百名大学生提供了见习、就业岗位。2009年，大学生就业形势凸显严峻，国家发出了以创业带动就业的号召。为让大学生创业就业不再困惑迷茫，朱箭飞再次萌发了开辟新创业项目的想法――创办吉林省大学生创业平台，以便为大学生找到更适合自己发展、解决就业见习创业的服务平台。这样讲创新与基础相结合的人最后才能走到大学生创业这座金字塔的顶端。
大学生创业的过程当中怎样提升自己的勇气和底气
大学生创业本身就有很多问题等着我们去解决，有很多困难等着我们去克服。日前，在今年第八期高校毕业生自主创业培训班毕业典礼上，一位老师感慨地说：“现在参加创业培训班的人比以前多了，但与几千人的高校毕业大军比起来，真正能迈出这一步的大学生仍然少之又少，勇气、资金、项目、经验、环境等都成为制约大学生创业的重要因素。”
近年来，为引导高校毕业生转变传统就业观念，我市出台了一系列优惠政策，鼓励大学生创业。许多大学生在接受采访时都流露出创业的意图，但真正付诸行动的人并不多，创业者数量明显偏少。据了解，近年来，我市共举办了21期高校毕业生自主创业培训班，有201名应届普通高校毕业生领取了自主创业证，只有28人开办了自已的企业。
鞍山师范学院2008届毕业生王贵人正开办着一家滑轮学校。他说，他们美术系一个年级200多个毕业生，只有他一个自主创业者。受传统观念影响，很多学生毕业时想的还是如何进入党政机关、事业单位和知名企业，没有找到合适工作的往往在家待业。面对就业压力，多数大学毕业生主观上希望通过自主创业来体现自身价值，可面对风险，又缺乏足够的勇气走上创业之路。 “毕业前，我们同寝室几个人天天商量创业的事，可不知道到底干啥好，事也没做成。”王贵人告诉记者，上学时，他就和几个朋友一起商量毕业后走自主创业之路，可事实上真正自己做老板的只有他一个人。“其实最难的是做决定，一旦决定好了，做事就有了目标，一切反而简单了。”王贵人说，有勇气面对困难，是一个重要的条件。他的滑轮班刚起步时只招到了几名学生，但他并没有气馁，仍然坚持，学校规模越来越大，现在他已经在铁东、立山各公园里有了自己的场地和固定学员。
1997年毕业的谷先生从事了十多年技术工作，今年才开始创业。他告诉记者，他特别羡慕刚毕业的大学生，有激情去创业，又有政策扶持，这些都是他不具备的。他认为，年轻就是资本，刚走出校门的大学生应该鼓起勇气创业，实现自己的人生价值。这样经历过大学生创业的人，在以后的人生道路上绝对会比别人先行一步。
