General solar road lamps use low-voltage energy-saving lamps, low-voltage nanolamps, electrodeless lamps, LED light sources, the following for everyone to share the difference between solar street light sources:
1, low voltage energy-saving lamp: low power, high light efficiency, but the service life of 2000 hours, low voltage lamp black, generally suitable for solar lawn lights, garden lights.
2, low pressure sodium lamp: low pressure sodium lamp light efficiency is high (up to 200Lm/w), less use.
3, electrodeless lamp: small power, high light efficiency. The lamp is used under 22V(pure sine wave, frequency 50 Hz) ordinary mains conditions, the life can reach 50,000 hours, and the service life on solar lamps is greatly reduced and the ordinary energy-saving lamps are almost the same (because solar lamps are square wave inverters, solar power 220V output frequency, term, voltage are not compared with ordinary mains.
4, LED: LED light source, long life, up to 1,000,000 hours, low working voltage, no need for inverter, high light efficiency, domestic 50Lm/w, imported 80Lm/w, with the progress of technology, LED performance will be further improved. LED as a solar street light source will be a trend.
