1. Energy saving, high luminous efficiency of LED, ordinary incandescent light effect is 15-20LM/W, high light efficiency of LED lamps can reach 60-100LM/W; that is to say, traditional 60W incandescent lamps use about 10W LED lamps can be replaced; LED lamps can save about 20% energy compared with fluorescent lamps.
2. Environmental protection, LEDs belong to semiconductor devices and do not contain heavy metal elements such as mercury; traditional energy-saving lamps have mercury pollution during the manufacturing process and after they are used and discarded.
3. Long lifespan, the theoretical life of LED is 100,000 hours, and the life of LED lamps with better quality is 25,000 hours. The life of incandescent lamps is only 1,000 hours, and the life of fluorescent lamps is more than 7,000 hours.
4. The color rendering index is high, that is, the degree of color reproduction is high.
5. LED is a DC drive, which is more suitable for solar lamps. The life of the solar panel is 10-15 years. In addition, the life of the LED is relatively long, and the maintenance cost of the overall lamp will be greatly reduced; the maintenance cost caused by frequent replacement of the light source is avoided.
