As we all know, LED is called the Fourth generation of light source. With many advantages, such as energy saving, environmental protection, safe, long lifespan, low power consumption, low heat, high brightness, waterproof, shock, easy dimming, beam concentration, easy maintenance and so on, LED can be widely used in various instructions, display, decoration, backlight, general lighting and other fields.
LED advantages: high conversion efficiency, environmental protection, long lifespan, low power consumption, easy to dim, colorful, stable and stable beam, start without delay
Incandescent: low efficiency of electro-optical conversion (about 10%), short life (about 1000 hours), high heat temperature, single color and low color temperature;
Fluorescent light: electro-optical conversion efficiency is not high (about 30%), hazardous to the environment (including mercury and other harmful elements, about 3.5-5mg / only), not adjustable brightness (low voltage can not start glare), ultraviolet radiation, flicker, Slow, rare earth raw material prices (phosphor accounted for the proportion of cost increased from 10% to 60 ~ 70%), repeated switch affect life;
High-pressure gas discharge lamp: power consumption, the use of unsafe, short life, heat problems, and more for outdoor lighting.
So LED is a good choice for us to Environmental causes.
