LED Lighting

Light-emitting diodes (LEDs) convert electrical power into light energy. An LED is essentially an electroluminescent semiconductor chip. It is fixed onto a bracket using silver adhesive or white adhesive, then bonded to the chip and circuit board via silver or gold wires. The exterior is encapsulated with epoxy resin to shield the internal fine wires, and a housing is mounted lastly. This structure gives LED lamps excellent shock resistance.

LED lamps deliver superior energy efficiency while maintaining the same brightness. They operate at low voltage and current, offering a high safety margin, which makes them ideal for hazardous environments such as mines.

LEDs feature extremely high luminous efficiency. Currently, the luminous efficacy of mainstream high-power single LEDs exceeds 100 lm/W, and finished LED energy-saving lamps achieve an actual luminous efficacy of 60 lm/W. By comparison, incandescent lamps only reach around 15 lm/W.
