LED Bulb
ght principle, light-emitting efficiency and lifetime comparison: 1). Incandescent: tungsten light heat to 2000 degrees, eight the following Baidu will darken the red. Efficiency of electrical energy into light energy less than 3%, life three thousand hours; 2). Fluorescent: Current produce ultraviolet light, to stimulate the phosphors, ultraviolet light will reveal a part of. Electrical energy into light energy efficiency is 10%, life 6000-8000 hours; 3). LED Bulb: LED electroluminescent semico
