Obvious advantages of LED advertising

LED (Light - Emitting - Diode Chinese for light emitting diode) is a semiconductor capable of converting electrical energy into visible light, it has changed the principle of incandescent tungsten filament and energy-saving lamps three color luminous powder, and the electroluminescence. According to the analysis, the characteristics of LED is very obvious, long life, high luminous efficiency, no radiation and low power consumption. The spectrum of LED is almost all concentrated in the visible band, and its luminous efficiency can reach 80 ~ 90%. The reporter also LED and the ordinary incandescent lamp, energy-saving lamps and T5 three spiral fluorescent lamp has made a comparison, results show that the optical efficiency of ordinary incandescent lamp is 12lm / W, the life of less than 2000 hours, the light effect spiral energy-saving lamp is 60lm / W, the life of less than 8000 hours, T5 fluorescent lamp is 96LM / W, life is about 10000 hours, white LED and 5 mm in diameter is 20 ~ 28lm / W, life can be more than 100000 hours. It was also predicted that the future LED life limit will be infinite.

Is generally believed that energy-saving lamps can save 4 / 5 is a great feat, but also LED than the energy-saving lamp energy saving 1 / 4, this is a great reform of solid light source. In addition, LED also has other advantages, high light quality, basically no radiation, is a typical green lighting source, reliable and durable, low maintenance costs, etc.. Because LED has more than other solid light source can not match the characteristics of 10 years after the LED lighting industry will be the main source of light. LED is also difficult to complete lighting although LED has many advantages, but after 5 to 6 years of development has not yet been accepted by the market and consumers. Beijing pine industry company in a report analysis: the domestic and foreign research and development and production of white LED can not reach the requirements of lighting. Low power is the bottleneck.

It is understood that, at present, the monomer LED power on the market generally below 1W, also no big power LED, this is LED difficult to immediately become the biggest bottleneck in lighting. Factors affecting LED have LED components. As a result of the small LED light features, unlike incandescent and fluorescent lamps, it has the problem of uneven white light. Up to now there is no white light LED manufacturers to provide detailed information on the components of the failure or technical specifications, but also no lighting source with the standard LED lamps.

According to the analysis of domestic LED research experts, LED in luminous efficiency, color temperature and color rendering index maneuverability has its limitations, progress is slow, high luminous flux and high efficiency are the technical problems in the future in the development of the white LED.
