What kind of light source is best for solar street lights

Outdoor lighting New rural solar street lights , the most suitable light source is energy-saving lamps, sodium lamps, LED lamps or electrodeless lamps? Let the editor analyze it for you:

1. In terms of luminous efficiency, these lamps can achieve more than 80 lumens per watt, which can be said to be comparable.

2. In terms of service life, LEDs only have the upper hand. Theoretically, LED chips have a long life. In practice, the life of LED lights is not as good as expected due to the decay of light and the life of other electronic components. Other light sources have also been improved, and their service life is increasing.

3. In terms of environmental protection, LED still has the advantage. The LED lamp contains no toxic substances and no ultraviolet radiation.

4. As far as the matching of solar power is concerned, LED is a low-voltage power supply, which is the easiest to match the power of solar power. Other lamp types require a large boost amplitude, large power conversion losses, and large electromagnetic interference.

7. In terms of mechanical strength and environmental adaptability, LED lamps and sodium lamps are relatively good
