A new type of semiconductor electro-optic source to change the light world

Semiconductor lamp has low power consumption, long service life, and no flash, no effect on visual acuity. We have been too familiar with lighting, incandescent lamp, fluorescent lamp, energy saving lamp, lamp and other lamps, in daily life can be seen, but the LED semiconductor light source, I believe we are not seen, because in the past it has been in the laboratory. From a month ago, China's patent office issued the world's first practical new semiconductor light source patent certificate, the product finally ushered in a huge opportunity from the laboratory to the mass market. Moreover, the lighting revolution initiator in Guangzhou, is a typical Chinese local enterprises. It is understood that this efficient green light source, there are many of its obvious characteristics and advantages of Electro Optics: such as environmental protection, energy saving, no flicker, etc., so it is known as the third revolution in the field of human lighting. Experts predict: semiconductor lighting will replace the traditional lighting in 2015.

Review

Semiconductor lighting utility Chinese walk in the world in front of the first industrial revolution triggered a "microelectronics revolution", semiconductor technology is giving birth to another "lighting revolution". With the emergence of the third generation semiconductor materials GaN semiconductor technology, positive human dedication is another achievement: with semiconductor light emitting diode (LED) as a solid state lighting semiconductor light source, to replace the traditional incandescent lamp and fluorescent lamp. The latest development of the white light 5W, spent about $30 million in research funding, while China has developed and produced 66W, 100W products, and even can be customized. Pengzhou dragon Guangzhou city Beijing Optoelectronics Technology Co., told reporters: "in the field of semiconductor lighting, we have a number of independent intellectual property rights of technology, using semiconductor quantum well type electric light source, the first to solve the problems of the technology in practical lighting in the world, launched a semiconductor lighting products the power from the 2W1000W, walking in front of the semiconductor lighting industry. Recently, the relevant departments of the government of Guangzhou will hold a press conference to promote the product to the world."

Semiconductor lamp low energy consumption for a lifetime not two semiconductor light of what was good? Guangzhou City, Beijing, Tianjin Photoelectric Technology Co., Ltd., told reporters: "in the same brightness, the semiconductor lamp power consumption is only 1 / 10 of incandescent lamp, and life is incandescent lamp of the times. 6 hours a day, a lamp can be used for 50 years." At present, all the service life of the lighting lamp in 3000-5000 hours, some even less than 1000 hours. And now widely used in all kinds of electric light source also showed many shortcomings, such as the color index is low, a great impact on the vision; luminous all-optical spectrum and a full range of increased manufacturing and use cost, reduces the use efficiency; and increase the power of active and reactive power loss and many other issues, and clearly the development of modern civilization, the modern environment is more and more high lighting requirements are not consistent. In addition, the semiconductor lamp can emit a variety of colors, can be said to be the true colors. Fluorescent lamp can not solve the problem of strobe, but this problem is not a semiconductor lamp, is the true meaning of "green lighting". Because the semiconductor lamp has the advantages of energy saving, long service life, maintenance free, easy to control, environmental protection and other advantages, so the industry generally believe that as the semiconductor transistor replacement tube, semiconductor lamp to replace the traditional lamp is also represent the general trend. For semiconductor lamps, red light, yellow light is the low-end products, this lamp has been mass production, which is the most competitive production costs, has been used for road lighting, decoration and other special lighting. But low cost, high brightness, high power white light is the high-end products, but also to practical products.

Dialogue

Future to let the semiconductor lamp price is lower than the ordinary incandescent lamp reporter (hereinafter referred to as "record"): now the semiconductor lighting is very hot, what time do you start to enter this industry? Pengzhou Dragon (hereinafter referred to as Peng): I was studying in the early days of Optoelectronic Engineering in Australia, interested in it. Reporter: when has a substantial breakthrough, that is, to make it from the laboratory to practical series products? Peng: three years ago has been studied, and later improved technology, selection, trial production, to the end of last year can produce a series of products. Reporter: what are your products now? What is the market outlook? Peng: we can see the lights we have, we also have eye protection lamp, solar emergency lights, solar lights, etc.. We hope that a year can do 10 billion of the marketing scale, are now in foreign countries such as Germany, the United States and Canadian customers, Guangzhou University City, Hongkong Vitoria park is also used, but the volume is not large. Reporter: in the current Chinese market, it is difficult to popularize semiconductor lighting it? Peng: difficult. Because of its relatively high prices, coupled with the average household lighting power consumption is not large, so the promotion of some difficulties, and now still need some lighting for a long time, large power companies will choose. But we believe that with the continuous innovation of technology, the future price of semiconductor lamps and incandescent lamps will be the same, or even lower, then it will be all the world of semiconductor lamps.
