The domestic Decorative Lamp

Has been developed to support the efforts of the LED lighting industry gradually increased. In 1998, the exclusion of 6 billion yen in Japan started “21st Century Light Plan”; the United States since 2000, $ 500 million to implement the “National Semiconductor Lighting Plan”; same year, the EU has also announced the launch of the “Rainbow Plan.” Despite the early start in the LED industry in China, but government support is not enough, until 2009 the Ministry of Science “City million LED project” files launch, the domestic Decorative Lamp industry will usher in a larger development project launched LED around the race.

As the heat increases the domestic market, LED industry was once caught in the concept of flying, defiant, scarce innovation dilemma. Part of the installation of high-power LED lights in the demonstration project, the result is not satisfactory, one after another night out the lights, life is short, bright enough, maintenance problems and other issues. Already installed solar lights, and later to the thermal power light, highlights the shortcomings of saving money is not festival, a serious blow to the confidence of LED lights around the installation, the LED Strip Light industry, impeding the healthy and rapid development.

Fortunately, the state always to promote the development of LED industry as a strategic direction. May 19, issued by the Ministry of Science and re-launched the second batch of pilot and demonstration projects, LED industry continues to develop a clear strategic direction for the development of Led Tube industry new impetus, the future prospects of the domestic market.

Today, LED industry barriers focused on the high cost of initial installation. In actual fact, LED initial installation price than the traditional high-energy light, but in the long term economic benefits are considerable. In this regard, Group Sales Director Bai Yuxiang German sources to reporters calculations. Bai Yuxiang introduced, compared with the traditional high pressure sodium lamp. If you achieve the same brightness, 200-watt high pressure sodium lamp need, solar LED lights only low-power 20-watt, 10 hours a day according to the lighting needs of the industrial use of electricity one yuan terms, high pressure sodium lamp per year for each tariff 200W * 10 小时 * 365 days * 1 yuan = 730 yuan. The low-power solar thermal power LED lights do not need, you can save per lamp per year on electricity up to 730 yuan. This does not include the initial installation of high-pressure sodium lamp included cables and other equipment needs, long-term need for manual maintenance costs. Solar small power LED is not the cost of laying cables, no manual maintenance costs, no electricity expenditures. “Small solar-power LED with a higher than normal high pressure sodium lamp installation fee, but 2-3 years can recover the full investment.” Bai Yuxiang said.

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.
