LED chandelier (Light-Emitting-Diode is a light-emitting diode) is a kind of energy can be converted into visible light semiconductor, it changed the incandescent tungsten light and energy-saving lamps three primary colors of light principle, and the use of electric field light. According to the analysis, LED chandelier characteristics are very obvious, long life, high luminous efficiency, no radiation
Shot with low power consumption. LED chandelier spectrum almost all concentrated in the visible light band, the luminous efficiency of up to 80 ~ 90%. The results show that the luminous efficiency of ordinary incandescent lamp is 12lm / W, the life is less than 2000 hours, the luminous efficiency of spiral energy-saving lamp is 60lm / W, the life is less than that of ordinary incandescent lamp, spiral energy saving lamp and T5 trichromatic fluorescent lamp. 8000 hours, T5 fluorescent lamp was 96lm / W, life of about 10,000 hours, while the diameter of 5 mm white LED is 20 ~ 28lm / W, life can be greater than 100000 hours. It is also predicted that the future LED life limit will be infinite.
Compared with the traditional light bulbs, LED is superior to:
· No delay delay, faster response time, the traditional glass bulb has a delay of 0.3 seconds to prevent rear-end.
· Stronger seismic performance.
· High luminous purity, no shade filter, light wavelength error within 10 nanometers.
The luminous heat is very small, the heat resistance of the lamp material is not very high.
· The beam is concentrated, easier to control, and does not need to be condensed with a reflector, which helps to reduce the depth of the fixture.
* Low power consumption, to achieve the same brightness of traditional light bulbs, the power consumption is only 6% of the traditional light bulbs, saving fuel.
* Long life, no filament structure does not heat, the normal use of more than 6 years.
