Light bead is a semiconductor device that can convert electrical energy into visible light in the solid state. It changes the incandescent tungsten filament light-emitting and energy-saving lamps three-color powder light-emitting principle, the use of electric field light-emitting. Its acronym word is LED. the driver is installed at the bottom of the LED bulb, the appearance can not be seen.
LED light beads are characterized by small size, low power of a single bead, good heat dissipation, energy saving and environmental protection, long service life. In addition, LED light beads can also be used to achieve diverse lighting effects through different color combinations, such as monochrome, seven-color, full-color and so on.
