LED chandelier (Light-Emitting-Diode) is a semiconductor that converts electrical energy into visible light. It changes the principle of incandescent tungsten light emission and energy-saving lamp three-primary color luminescence, and uses electric field luminescence. According to analysis, the characteristics of LED chandeliers are very obvious, long life, high luminous efficiency, no spokes
Shoot with low power consumption. The spectrum of LED chandeliers is almost entirely concentrated in the visible light range, and its luminous efficiency can reach 80-90%. Comparing LED with ordinary incandescent lamp, spiral energy-saving lamp and T5 trichromatic fluorescent lamp, the results show that the luminous efficiency of ordinary incandescent lamp is 12lm/W, the service life is less than 2000 hours, the luminous efficiency of spiral energy-saving lamp is 60lm/W, and the service life is less than 8000 hours, T5 fluorescent lamp is 96lm / W, life expectancy is about 10,000 hours, and white LED with diameter of 5 mm is 20 ~ 28lm / W, life can be more than 100000 hours. Some people also predict that the future LED life limit will be infinite.
Compared with traditional light bulbs, the advantages of LEDs are:
· No delay in lighting, faster response time, and a traditional glass bulb with a 0.3 second delay to prevent rear-end collision.
· Stronger seismic performance.
·High luminescence purity, no need to filter the filter, the optical wavelength error is within 10 nm.
· The heat of luminescence is very small, and the heat resistance of the luminaire material is not very high.
· The beam is concentrated, easier to control, and does not need to be concentrated by the reflector, which helps to reduce the depth of the lamp.
· Low power consumption, when the equivalent brightness of traditional light bulbs is reached, the power consumption is only 6% of the traditional light bulb, saving electricity and fuel.
·Long life, no filament structure, no heat, normal use for more than 6 years.
