LED Tube Light

Winter to the industry is a sweeping proposition, LED Tube current in the spring, not winter, not to micro and small enterprises, represented as a standard to measure the LED industry, the season, after all, have the ability to have real technology companies, faced with LED applications, a huge market, there is still a huge space beings, these enterprises in the spring is just beginning.

LED industry is facing temporary difficulties with the U.S. financial crisis and debt crisis in Europe caused by the external environment, the poor, with the national macro-control policy, and rising raw material and labor costs, RMB appreciation and so on, but I believe that the failure of a business can not blame the external environment, because the external environment, competition is the same case at the state fair, so the final analysis, caused by internal factors.

An industry also believes that the current points-based LED Tube Light loss, in addition to the impact of regulation by real estate, there are three reasons: First, the current upstream industry chain is not cutting-edge technology in their own hands, resulting in high production costs and sales costs are high, so do not make money. The second is the people’s deep understanding of the LED, and the homogenization of the product too, nothing new, both to aid in the form of dealers to sell. 3 is not a good marketing policy into the market, largely in low-end market price, the direct collision of the enemy 1000 injury self-harm 800 is too expensive. Fourth, there is no industry standard, I heard that LED to make money, and no one to point a, have been diverted.

LED Bulb glow with the traditional lighting works differently, it has a point light source, high brightness, narrow beam output and so on. Manufacture LED lamps first thing to consider is to take full advantage of the limited flux limited exposure range, the core of conventional lighting technology with light, the real technical content or in the light of the light distribution, street lighting and tunnel lighting has proven the case this point, the LED light source with a new type of lighting designers made ​​a higher demand. Inspired by the sentiment of human life, innovation comes from the technical personnel, companies should pay attention to human resources, so people-oriented.

The price of LED Tube Light

Temperature in the LED Tube Light section, the most effective means is to design a high thermal performance of the LED package, which is China’s LED industry in the near future be able to make significant progress on LED intellectual property one of the direction, the LED is a low-voltage electronic products, electrical safety requirements in a more relaxed, so the thermal conductivity of the substrate material can be used more, and we study this industry is small, resulting in repeated breach of foreign intellectual property disputes.

Improve the stability of the phosphor, is the mainstream of white LED technology, in this regard our current technology is relatively weak, short-term progress can not be exceeded for the majority of enterprises to seek a breakthrough in this area is difficult.

Color compensation technology is to compensate for the lack of color LED Strip Light color rendering index caused a reduction techniques, this technology is feasible from the principle of speaking, but in practice, faced with mixed light conditions the strict constraints of technology , so the practical value is not high.

3:6:1 RGB white line based on the mixing theory, this theory is based on our look at bright objects on the basis of this mixing technique can be successfully applied in white LED display technology, but application in the lighting program on the program this mixing is not much reference on the nature, this is because the human eye to visible light has a characteristic and average characteristics of a habit, and these two characteristics, which we unconsciously damage the eyesight of the important reasons.

Because according to the nature of lighting and clear, light on the object, the object into the eye through the reflection, so as to form a lighting process, as objects of various wavelengths of light absorption is different, so solid red, green and blue color Led Tube 3:6:1 mix through out the white light technology, itself, there are some color defects, exposure to the surface, because the red, green and blue are absorbed by different surfaces, different reflections, resulting in the reduction of CRI . Therefore, a three-color mixing technology and the production of white products, the surface should be in the components or the use of technical means within the product mix of light, so that a white light, rather than sending the light of three different objects in the illuminated surface mixing, the resulting lower CRI.

Red, green and blue color LED color mixing technology is a more mature white lighting technology, this technology because the distance between the different LED light mixing caused by the larger distance, mixed with the LED front mask, although the solution of the mixed light problem, but the light loss is an obstacle for the development of lighting in the formation toward the light barrier. Another person when direct lighting is not even watching the white; these two factors directly restricts the development of this technology.

Mixing of the three color LED technology, which is based on research to solve these two problems and proceed. Found that with decreasing distance between the LED chip from the mixed light decreases exponentially with trichromatic color powder coated surface concentration increases exponentially mixing effect is also enhanced in-depth study to start Three-color LED chip spacing decreased and concentration increased three-color look for an optimal balance between the point is a solution to the three primary colors of light mixed with the best programs, which make the tricolor white LED as a light source as possible.

At present, China is in the LED packaging industry, though a big country, but far behind in innovation and technology, mixing three primary colors red, green and blue light technology, to borrow the phosphor coated white LED technology, can achieve the perfect white effect.

LED Spotlight

According to statistics, in 2010 LED Flood Light the global packaging industry sales reached $ 12.8 billion, with Japan the largest share, about 27%. Led the industry from global competition in the market point of view: After decades of development, the global industry led the formation of the United States, Europe, Asia, the three pillars of competition. The main producers are: cree, hp, Siemens, Osram, Nichia, Toyoda Gosei, Seoul Semiconductor, Samsung, Epistar and so on.

LED Spotlight is a low-voltage cold-dot semiconductor light source, complete this sentence summarizes the characteristics of LED, and in our product development applications, which is characterized by endless, we are pursuing is the traditional light source, the required goals, which kinds of consciousness no matter right or wrong, but it is fit to the application of LED will have a certain degree of difficulty, the present situation of the integration LED light source, high voltage LED light source, I think this is the stage of product development to a certain level of semiconductor technology, cooling technology reach a certain level, I think that out of the two technologies is inevitable.

LED Tube Light fatal drawback is that heat accumulated effect, within the 3 mm2 lost more than half-watt power to generate heat (since 1 watt LED electro-optical conversion rate of less than 50%), while the integrated LED exacerbated this effect more so, even carrying a heavy thermal shell, can not completely solve the LED heat dissipation effect. LED is a point light source, so we source the design basis should be established on the basis of point light sources, on the basis of improved heat and light type of problem, our engineers are currently facing the most critical issues.

Other LED application product development as the development will still go through a tortuous process, this process is undeniable that the technology will have a short-lived (like the Chinese CVD), for experienced engineers in terms of what we have to grasp LED technology is the mainstream, great direction must not change.

white LED Panel

With the LED Tube Light performance continued to improve, the application also will rapidly expand the market, hidden reason behind the use of GaN, AllnGaP high-brightness light-emitting materials, LED, has a long life, energy saving, shock, low voltage drive and other outstanding characteristics, and beyond the light bulbs and halogen, and high luminous efficiency of LED is gradually in recent years been developed, therefore, the future development of high-brightness LED market, will be more rapid and extensive growth.

The most obvious of which is the penetration rate of white LED Panel , 90 late in the context of a more eco-friendly look forward to being the market, but also stimulated the rapid development of industry-related technology. For now, the main applications include white LED LCD backlight mobile phones and car interior lighting, which alone accounted for the LED market has about 25% of overall sales.

The other part of lighting applications, is in a fledgling state. General building lighting, often accounting for 20% of the electricity consumed in Japan, more than 1,000 per year 90 billion kWh. So for the next generation of energy-saving light sources expect quite large, but unfortunately so far, white LED Panel also can be used in only a very small range. Because, like a small 5mm white LED, not like a light bulb or fluorescent light, as only one can get the amount of light required for use of the environment. So if you want to step into the LED architectural lighting, the overall need for greater technical breakthrough is the job.

The basic structure of high-brightness white LED

There are basically two ways white LED. One is the multi-chip type is a single chip type. The former is the red, green and blue LED Flood Light packages together, but also to produce white light, which is the blue or violet, UV LED as light source, with the use of phosphors in white light. The former, it is necessary to combine all the characteristics of LED, the drive circuit is more complex, the latter type, then a single chip, LED only one species, circuit design easier. Further divided into two single-chip-type, one is the light source using blue LED, the other is the use of near-ultraviolet and ultraviolet light. Now, the white LED on the market are mostly blue LED with YAG phosphor.

LED Tube Light industry

From January to July this year, LED Tube Light industry, new investment of more than 100 billion yuan.Traditional lights are far less price competitive

Despite the huge investment, but in view of technical problems, that entry is actually about 70% of companies engaged in the downstream packaging and application services, and the two parts of the total profit of about 10% to 20% of the upstream and middle reaches of the wafer and chip business profits up to 70%. Industry sources say that the high-end chips, and now more than 80% from Taiwan or overseas, the core technology at this stage is still mainly concentrated in Japan and U.S. companies.

LED Underground Light account for 40% to 60% of the cost of the chip, the high cost of raw materials and technology, leading to the loss of price competitiveness, the main reason for not successfully enter millions of households. Power than traditional incandescent light LED 5 to 9 times, the cost of traditional lamps are often more than twice the price of natural high. It is understood, however, in recent years, the price of the chip at an annual rate of decline of about 20%. In addition, the company has recently developed a technology that will reduce the cost of nearly Qicheng LED chip, and another company successfully reduced the price of an ordinary LED lamp energy saving lamp level.

In addition to technical improvements, conducive to the development of policy in the “five” plan to promote the next in succession. At present, Dongguan, Huizhou, Foshan, Shenzhen, Dalian, Xiamen, Nanchang, and the development of relevant industries in succession planning. Market rumors, LED industry standards and subsidies is expected by the end of the introduction.Five non-standard inferior products into products

Some analysts pointed out that the standard in the industry before the inevitable problems are not introduced, the various manufacturers of LED products is different specifications and different ways, reportedly 50% of products on the market there is no standard inferior product.

Therefore, the market began to question the led wall light industry has a bubble of excess capacity began. Experts point out that, LED is the trend will continue, but at this stage LED industry is not mature, real LED lighting market is not started. Local governments have committed to LED lights as a breakthrough, pull the entire industry, focused on the current LED landscape lighting, tunnel lights, street lamps and other lighting products.

THE PRICE ABOUT LED Bulb

In my mind, led wall light source with the current traditional very different, but we in the application of LED as a light source when the light is always in the old tradition to go, because we used to have the shackles of our innovative LED light source .

I can not say that he is a qualified expert of LED, but I do for most of the LED and some experts on a certain level of awareness is not high, because when they evaluate LED products are always standing tradition angle of the light source to evaluate the LED light source, so I think they are a qualified from the LED brick home.

I do not think the design is the LED Bulb currently on the market in this way, we can use thermal, optical principles to a consideration of the current section of the technology, learn from the optical hot, mostly not, the biggest problem is that current technology does not for standardization mode, so there is still much room for innovation.

Spoke of standardization, I would say we are counting on other people in a benchmark, our efforts this talent, this is not the correct view, the standard will give you hope and do not bring much benefit, because the standard rules of the game , you can not afford to participate in the formulation of rules of the game, not even think about how much from the rules of the game to enjoy the benefits, so the standards and specifications that are restricting someone else’s, for terms of an engineer should develop a standard to regulate their own first, and then disseminate restrict other people, you are the first “drive.” Standards is a slow process, so you should standardize their products, standardized product design processes, production processes, test specifications, and even the packaging, instructions, you can not do this, hope someone gives you a specification, you can do it?

The life of LED Tube Light

LED Tube Light, although life itself is a single LED up to 100,000 hours, but its application must be with a power conversion circuit, so the overall life of LED lighting integrated optoelectronic applications must be considered. But lighting with LED, in order to achieve matching requirements, power supply and drive circuit of life must be more than 100,000 hours, so that it no longer led lighting system bottlenecks. In considering the long life at the same time can not increase too much cost, power and drive circuit of life and costs are usually not more than one-third of the total cost of the lighting system, led lighting products in the early stage of development, we must strike a balance between power and drive circuit of the relationship between life and cost.

LED Panel Light as a light source is a notable feature in the low drive current conditions can still maintain its lumen efficiency, while the RGB polymorphism

Mixed to form white light, through the development of a digital RGB LED for hybrid control system that allows the user to a large range of LED brightness, color and tone to be adjusted, giving a new visual to enjoy. In the urban landscape lighting applications, LED light source can be under the control of the microprocessor can be changed according to different patterns to form a night scene in the attitudes of dynamic effects, will be reflected in this regard compared to other LED light source has a unique a competitive advantage.

As a special lighting, Led Tube with high-tech health care, high risk, high barriers to entry and so on. Domestic LED lighting market is also the medical still in its infancy, both market size and production companies are also less. As the state of health and national health concern and increased investment, the rapid development of medical device industry, the growing demand for medical lighting, but also to the development of LED medical lighting brought new opportunities and challenges.

Compared with the conventional medical lighting, LED surgical lighting energy savings in addition to its direct effect, it has the effect of improving the operating room laminar flow of the outstanding advantages, it also significantly reduces the operating room cleaning system one-time investment, saving cleaning energy consumption of the additional energy-saving effect. According to the number of China’s medical institutions across the country used about 10 million units and 73 000 surgical shadowless operating room basis, surgical shadowless 100,000 (average power consumption over 1000W) power consumption of more than 180 million annual kWh (according to each 1000W × 6h × 300d calculation); currently used in hospital operating room laminar flow of air purification system, the average power consumption of more than 3000W, 7.3 万 operating rooms to reach 1.892 billion in annual power consumption kWh (per 3000W × 24h × 360d basis), only preceding three years of total consumption had reached 25.9 billion kWh, more than the Three Gorges hydropower project generating capacity (84 billion kWh) of 3%, and has not yet taken the required LED lighting of hospital inspection lamps, LED headlights and other medical special lighting power consumption.
