The light-emitting Diode (LED) is a Light source with high efficiency and long service life. Leds were invented in the 1960s, and in subsequent decades were primarily used as indicators for electronic devices such as radio recorders. It lasts for 100,000 hours and is 100 times longer than an ordinary incandescent bulb. LED light source mainly includes ring light source, strip light source, linear light source, return light source, back light source, outer coaxial reflection light source, inner coaxial point light source, half-sphere ridge cover light source and so on.
