LED definition LED (Light Emitting Diode), also known a […]
LED (Light Emitting Diode), also known as LED, uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, carriers in the semiconductor recombine, releasing excess energy and causing photon emission to generate visible light.
High efficiency and energy saving only consumes a few kilowatt hours in a thousand hours (normal 60W incandescent lamp consumes 1 kWh for 17 hours, ordinary 10W energy-saving lamp consumes 1 kWh for 100 hours)
Long life The semiconductor chip emits light, no filament, no glass bubble, no fear of vibration, not easy to break, and the service life can reach 50,000 hours (the ordinary incandescent lamp has a service life of only one thousand hours, and the ordinary energy-saving lamp has a service life of only 8,000 hours)
Light health Light and ultraviolet rays are not contained in the light, no radiation is generated (normal light lines contain ultraviolet rays and infrared rays)
Green and environmentally friendly It contains no harmful elements such as mercury and antimony, which is good for recycling and utilization, and does not cause electromagnetic interference. (Ordinary lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps can cause electromagnetic interference)
Protecting vision DC drive, no stroboscopic (normal lights are AC drives, it will inevitably produce stroboscopic)
High light efficiency and low heat generation: 90% of electrical energy is converted into visible light (80% of ordinary incandescent light is converted into heat, and only 20% of electrical energy is converted into light)
High safety factor The required voltage and current are small, the heat is small, and there is no safety hazard. It can be used in dangerous places such as mines.
Large market potential Low-voltage, DC power supply, battery, solar power supply, can be used in remote mountain areas and outdoor lighting, such as lack of electricity, less electricity.
