LED energy-saving lamp is a new generation of lighting source after compact fluorescent lamp (that is, ordinary energy-saving lamp).
LED is a semiconductor light-emitting diode, a solid-state semiconductor device that turns the electricity directly into light. LED energy-saving lamp is used with high brightness white LED light emitting light source, high luminous efficiency, low power consumption, long life, easy to control, avoid maintenance, safe and environmental protection; Is a new generation of solid cold light source, light color and soft, bright, colorful, low loss, low energy consumption, green environmental protection, suitable for family, shopping malls, Banks, hospitals, hotels, hotel various other public lighting field, director of the time. No flash direct current, good protection for eyes, is the best choice of lamp, flashlight.
The heart of the light-emitting diode, LED is a semiconductor chip, chip attached on a bracket, at the end of the end is negative, the other end connected to the power of the anode, the whole chip is encapsulated by epoxy resin. The semiconductor wafer consists of two parts, one of which is the p-type semiconductor, where the hole occupies the dominant position and the other is n-type semiconductor, which is mainly electron. But when these two semiconductors are connected, they form a p-n junction. When a current flows through a wire to the chip, the electron will be pushed P area, electron and holes in the P zone compound, then will be issued in the form of photon energy, this is the principle of LED. Because LED light is not high heat, convert electric energy as much as possible to light energy, and ordinary lamp because of heat to heat a lot of electrical energy into heat energy, white waste. Leds, by contrast, are energy-efficient.
LED energy-saving lamps as a category of LED general lighting, its name originates from the traditional lighting bulb, energy-saving lamps. LED energy-saving lamps are similar to traditional energy-saving lamps, which can satisfy the traditional aesthetic of consumers. The features of LED energy-saving lamp: low cost, high luminous efficiency, large luminous area, no glare, no heavy shadow.
