LED energy-saving lamps are a new generation of illumination sources after compact fluorescent lamps (ie, ordinary energy-saving lamps).
An LED, a semiconductor light-emitting diode, is a solid-state semiconductor device that converts electricity directly into light. LED energy-saving lamp is a high-brightness white LED light source with high luminous 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, colorful, colorful and low light color. Loss, low energy consumption, green and environmental protection, suitable for long-term lighting in homes, shopping malls, banks, hospitals, hotels, restaurants and other public places. No flash DC, it has a good protection for the eyes, it is the best choice for desk lamps and flashlights.

Light-emitting diode, the heart of the LED is a semiconductor wafer. One end of the wafer is attached to a bracket, one end is a negative pole, and the other end is connected to the positive pole of the power source, so that the entire wafer is encapsulated by epoxy resin. The semiconductor wafer consists of two parts, one part is a P-type semiconductor, in which the hole dominates, and the other end is an N-type semiconductor, which is mainly electrons here. But when the two semiconductors are connected, they form a P-N junction. When a current is applied to the wafer through the wire, the electrons are pushed toward the P region. In the P region, electrons recombine with the holes, and then the energy is emitted in the form of photons. This is the principle of LED illumination. Because the LED lamp does not generate heat, the electric energy is converted into light energy as much as possible, and the ordinary lamp converts a lot of electric energy into heat energy due to the heat generation, which is wasted. In contrast, LED lighting is energy efficient.
