LED lighting-emitting principle and advantages

LED lighting-emitting principle and advantage: LED light-emitting diode is short. By the gallium (Ga) and arsenic (AS), phosphorus (P) compounds made of diodes, when the electron and hole recombination radiation when visible light, which can be used to make light-emitting diodes in the circuit and equipment as instructed lights, or the composition of text or figures. Of red phosphorus and gallium arsenide diodes, gallium phosphide diode glow green, yellow hair silicon carbide diodes. At present there can be issued a similar incandescent light color LED, which provides a modern lighting, long life, high efficiency lighting, the most valuable is, LED devices with up to 50,000 or even 100,000 hours life, for many occasions the application characteristics.
LED light with natural light is different, the spectrum is not continuous, the lack of the infrared part, so different with incandescent lamps, LED by the radiant heat generated is not shed, but must be shed by conduction, which is known as cold- LED strip of reason. LED has the following advantages:
Energy efficient: the white LED is now known to most energy-efficient white light source of the device. Power consumption of only a few degrees one thousand hours (regular consumption of a 60W incandescent seventeen hours of electricity, the general consumption of 10W energy saving lamp one hundred hours of electricity)
Long life: light-emitting semiconductor chip, no filament, no glass bulb, afraid of shock, not broken, the service life of up to 50,000 hours (incandescent only a few hundred hours of life, ordinary life of energy-saving lamps only eight thousand hours )
Green: No harmful elements such as mercury and xenon, is conducive to recovery and use, and will not produce electromagnetic interference (ordinary lamps contain mercury and lead, elements, energy-saving lamps, electronic ballasts will produce electromagnetic interference, and light mercury tubes still exist)
Eye protection: DC drive, no flash (normal lights are AC drive, it will inevitably produce strobe)
Light efficiency: small heat: 90 percent of electricity into visible light (incandescent 80% of the energy into heat, only 20% of electrical energy into light energy)
Market potential: low voltage, DC power supply, battery, solar power can be can be used for outdoor lighting in remote mountainous areas and lack of electricity, less electricity places.
