LED is a semiconductor light-emitting diode, which is a solid-state semiconductor device that can directly convert electricity into light. LED energy-saving lamp is a high-brightness white light-emitting diode light source with high light efficiency, low power consumption, long life, easy control, maintenance-free, safe and environmentally friendly; it is a new generation of solid cold light source with soft, bright, colorful and low light color Consumption, low energy consumption, green environmental protection, suitable for long-term lighting in homes, shopping malls, banks, hospitals, hotels, restaurants and other public places. Flash-free DC power, which protects the eyes well, is the best choice for table lamps and flashlights.
The heart of the LED is a semiconductor wafer. One end of the wafer is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire chip is encapsulated by epoxy resin. A semiconductor wafer consists of two parts, one is a P-type semiconductor, where holes dominate, and the other end is an N-type semiconductor, where electrons are mainly. But when these two semiconductors are connected, a P-N junction is formed between them. When a current is applied to the wafer through a wire, the electrons are pushed to the P region, where the electrons and holes recombine, and then the energy is emitted in the form of photons. This is the principle of LED light emission.
Spiral energy-saving lamps are different in style from ordinary energy-saving lamps. The tube is thought to have a spiral shape, which not only makes it more beautiful in appearance, but also more concentrated in light intensity. The lighting effect of the spiral energy-saving lamp is stable and it is not easy to flash. Vision does not cause too much burden, so energy-saving lamps are also called eye protection lamps, which are widely used in schools and office environments. Many consumers always use the power of tungsten light bulbs as a reference when purchasing energy-saving lamps. Because most manufacturers will list the power of the product itself and the control brightness on the packaging, these are the power of tungsten light bulbs, so energy-saving lamps are also called eye protection lamps, which are widely used in schools and office environments.
