What are the characteristics of led energy-saving lamps?
LED energy-saving lamps are a new generation of light sources after compact fluorescent lamps (that is, ordinary energy-saving lamps). LED energy-saving lamps are environmentally friendly, contain no mercury, can be recycled and reused, have low power, high luminous efficiency, and long life. Switch, small light attenuation, rich color, dimmable, and rich change.
characteristic
1. High efficiency and energy saving: Compared with the same brightness, 3W LED energy-saving lamps consume 1 kWh in 333 hours, while ordinary 60W incandescent lamps consume 1 kWh in 17 hours, and ordinary 5W energy-saving lamps consume 1 kWh in 200 hours.
2. Long life: semiconductor chip emits light, no filament, no glass bulb, not afraid of vibration, not easy to break, the service life can reach 50,000 hours (the life of ordinary incandescent lamps is only one thousand hours, and the life of ordinary energy-saving lamps is only eight. Thousand hours).
3. Health: Healthy light. The light contains less ultraviolet and infrared rays, resulting in less radiation (ordinary light lines contain ultraviolet and infrared rays).
4. Green and environmental protection: It does not contain harmful elements such as mercury and xenon, which is conducive to recycling. Ordinary lamps contain elements such as mercury and lead.
5. Protect eyesight: DC drive, no flicker (common lights are AC drive, flicker is bound to occur).
6. High light efficiency: The light efficiency of a company in the laboratory has reached 260lm / W, and the single high-power LED on the market has also exceeded 100lm / W. The LED energy-saving lamp is manufactured. Due to the power efficiency loss, the light of the lampshade Pass-through loss, the actual luminous efficiency is 60lm / W, while incandescent lamps are only about 15lm / W, and high-quality energy-saving lamps are about 60lm / W, so in general, LED energy-saving lighting efficiency is equal to or slightly better than energy-saving lamps. (Data for May 2011)
7, high safety factor: the required voltage and current are small, the safety hazards are small, in dangerous places such as mines.
8. Great market potential: low voltage, DC power supply, battery and solar power supply, in remote mountainous areas and outdoor lighting, etc.
