What Are The Advantages Of LED Lights?

LED(light-emitting Diode) is a semiconductor that converts electrical energy into visible Light. It changes the principle of incandescent Light Emitting from tungsten and energy-saving Light Emitting from three-base powder, and USES electric field instead.According to the analysis, LED features are very obvious, long life, high light efficiency, no radiation and low power consumption.LED spectrum is almost all concentrated in the visible light band, its luminous efficiency can reach 80-90%.Will be LED with ordinary incandescent lamp, spiral energy-saving lamps and T5 trichromatic fluorescent lamps, the result shows: the ordinary incandescent light efficiency of 12 lm/W, life is less than 2000 hours, spiral energy-saving lamp luminous efficacy of 60 lm/W, life is less than 8000 hours, T5 fluorescent lamp is 96 lm/W, life is about 10000 hours, and a diameter of 5 mm white LED to 20 ~ 28 lm/W, life can be greater than 100000 hours.Some also predict that in the future, the upper limit of LED life will be infinite.


The advantages of leds over conventional light bulbs are:

Light up without delay, the response time is faster, the traditional glass bulb has a 0.3 second delay, to prevent rear-end

Stronger seismic performance

Luminous purity is high, do not need lamp shade filter, the error of light wavelength is within 10 nanometer

Luminescent heat is very small, the heat resistance of lamp material is not very high

Beam concentration, easier to control, and do not need to use reflector focus, is conducive to reduce the depth of the lamp

Low power consumption, reach the same luminance of the traditional bulb, power consumption is only 6% of the traditional bulb, save electricity and oil

Long life, no filament structure without heat, normal use in more than 6 years
