About the mechanism of light-emitting LED light source

Now, with the LED industry supply with mature, low barriers to entry, a large influx of small businesses, resulting in excess of the LED bulbs, and because its production capacity utilization rate is low, certainly compete in the market giant Philips brand (Philips), Osram (Osram) and GE, these manufacturers through vertical integration or strategic alliance layout, the main active occupation of LED lighting market. Whether exploited or through gross margin much larger rivals, small factories and thus escape the huge market pressure.
China has rich resources of non-ferrous metals, gallium, indium-rich, the world's total reserves of 70% -80%, which makes the development of semiconductor lighting industry in China has the advantage of resources. By 2010, the Chinese LED industry output will exceed 150 billion yuan. As early as 2002, Japan spent ¥ 5 billion to implement white light illumination, the program's budget of 60 billion yen.
With the rapid growth of LED penetration, along with the price war will come in 2010, because unlike the traditional lamp and LED downlight source separate from the sales model, in this pressure, some companies can not take into account quality and price competitiveness, may will fall to the merger or be doomed.
May 7, 2010 -12, Henan Province, lighting, lighting experts and entrepreneurs learn to organize his party visited Japan Japanese lighting situation, found that Japan's current situation is not satisfactory LED lighting.
In recent years, in light of the most interesting event is the rise of the semiconductor lighting. The mid-1990s, Japan's Nichia Corporation Nakamura, who through unremitting efforts, broke through the manufacture of blue light-emitting diode (LED) of the key technologies, and thus developed a fluorescent material to cover the blue LED technology produces white light source .
led the LightEmittingDiode (light emitting diode) acronym. New solid-state light-emitting diode is a cold light source, LED's most notable feature is the long life, high photoelectric conversion efficiency, good seismic performance, ease of use in the lighting system more widely. Under the same illumination, LED tube and power consumption than incandescent and fluorescent lifetime have clear advantages.
White light of various methods of development, and development of next-generation phosphors, LED luminous efficiency has led to a substantial increase in current industrial products from 45lm / w up to 100lm / w (2009, Cree's cold white light efficiency when at 350mA over 100lm / W, while the warm white light is more than 75lm / W), the level of research 160lm / w, the highest level of expectations of the target 200lm / w or more. Life of 40,000 to 80,000 hours.

LED lighting market focus gradually transferred to the home lighting market

Prior to the use of LED lighting often, mostly special purpose lighting and landscape lighting, these lamps in the lighting market in only a very small part of the future will serve as the lead LED gradually penetrate into the home lighting market in the past. With very different domestic lighting, landscape lighting, less demanding on the brightness, the lamp, for example. Most government procurement, price sensitivity is quite low, from this point can be seen on the market penetration of home lighting in one of two technical factors, the second is price. In indoor lighting, luminous efficiency, color rendering are all technical threshold.
Lighting products throughout the production process to low-power white light products, for example, the chip part of the total cost of the product is relatively small. Light manufacturing and marketing chain is also high value-added sectors, has not been established because the current marketing channels, channel costs account for about 25% of the total cost. In other words, chip, manufacturing, sales channels, including the proportion of the current cost of similar, which is currently in the field of LED lighting, traditional lighting companies slightly ahead of LED downlight business reasons.
According to the "2010-2015 China's semiconductor lighting (LED) industry investment analysis and forecast report" shows that with the steady improvement of luminous efficiency, the higher the efficiency, the backlight light source using the fewer number of LED chips, the same, LED chip The unit will continue to decline, mobile phone LCD panel with LED backlight also exists in this situation. In contrast, the family of LED general lighting market will continue to expand within a longer period of time. Unique advantages of LED lighting will be received, the entire lighting market is expected to be further expanded.
With the gradual penetration of the future to deepen LED, when the time to achieve 100% penetration of the market on a large scale of new capacity will be directly reflected in home lighting. Ordinary consumer demand is very high optical quality, the spending habits of the various regions are not always the case, therefore, extending the diversity of products, improve product quality is also a future direction of enterprise development.

LED lighting industry will usher in the development of high tide

China is currently the hottest LED lights, the Ministry of Science Ten thousand ten cities, driven by an amazing passion in advance, many people headlong into the market, appears to be the first lighting up. led lighting market heats up, from the moment the market, not to the future of LED lighting industry, the industry will usher in a period of rapid development.
Abroad, the current promotion of the first two areas is in 2,3, but this LED lights are very careful with foreigners. So even LED lights that make the blind boss is likely to become a "pioneer in the revolution", while the other two markets, but will develop in many industries "leading" force. At present there are 21 pilot cities, is expected to one million, the ministry plans approved 50 cities next year, is expected to 2 million, which is Chinese characteristics! Can be considered to create China speed! But the overall product maturity worrying; may also be lighting the first to be made a bad market, repeating some of the early LED downlight lamp is suspected, whether bubbles have more serious? Although very prosperous, very lively, can be expected after the government money, will eventually go through 2-3 years trained a number of good LED optoelectronic technology companies, this may be the ultimate purpose of government is located.
led lamp cup, should be concerned, lamp cup LED lighting is one of the first to start one of the areas, the program has been mainly the product is not mature enough, it is difficult large-scale application. From the previous casting, aluminum extrusion profiles changed now; but it can really solve the heat and power products have not seen, that is, so far do not have a commercial application product solutions. While the LED itself costs have dropped significantly, but the market has been no major improvement. Recently there are reports that some foreign Toshiba has introduced some light can be solved cup heat and power products and, if so, I think the market should be light cup will then follow T8-led, and soon up. The first LED is a promising area bigger one.
LED T8 tube similar applications, product solutions from the market point of view, there are close to commercial product launch, even that is the first to promote a mature market. Currently, Wal-Mart has started in the world with T8-LED in the replacement of traditional fluorescent tubes can be seen in this sub-field of hope is not far off. Current parking lot to do, shopping malls, advertising and other markets backlight; and the current production costs and prices have been near the point was close to business applications (150). Good product, both in the optical, thermal, and power handling are more mature program. Products are closest to commercialization. Of course, the current market, there are a lot of low-quality products. This is the biggest challenge. With the U.S. Energy Star standards and the introduction of the EU, I believe these problems will be greatly improved, that is, T8-LED commercial promotion also will begin.

In addition to connect to the network outside, LED tube also serve as the commander of a variety of household appliances. The Institute's Dr. Chen Xiongbin, at present they have to achieve a variety of electrical switches and adjustable controls.

Benefits of LED lights LED lights have many advantages

Into the field of LED light, lighting technology is a revolutionary leap. The development of LED lighting for the historic contribution of green, no less favorable than the high wire to the transistor from the era of vacuum tube era leap, even if the evaluation of large scale integrated circuit as the transistor to the changes across the same, and no exaggeration.

In landscape lighting, LED has a more unique advantages, can be sure, LED landscape lighting along the avenue of interdisciplinary integration, toward the artistic, intelligent, flexible in the direction of rapid development. LED is pregnant with opportunities.
In addition to mercury-free LED downlight source, energy, materials, electromagnetic interference-free environment, without harmful rays five advantages, in the lighting field, particularly in landscape lighting, there are many advantages. Such as: low-voltage power supply - no high-pressure part, much less to the cost of insulation, high reliability; accessories simple - no starter, ballast, or EHV transformers; simple structure - the biggest advantage with a solid light not inflated, no glass case, no gas sealing problems, impact resistance; controllable - fast response time (microseconds of magnitude) can be repeated frequently light off, almost no inertia, not tired; color simple and honest - - self-generated by the semiconductor PN junction color, pure, strong; rich colors - the three primary colors plus digital technology, the evolution of any color; lightweight structures - and materials, cost savings; strength and stiffness requirements for low lighting; - compact large LED lamp can be seen as cells from the LED, the LED is only the smallest magnitude square millimeters or less; flexible is good - LED compact light source, the LED can adapt to a variety of different geometric dimensions and space decoration lighting requirements, such as: point, line, surface, ball, different forms, as well as any art form of the light sculpture.
