New technologies are applied to solar street lights?
The size of both batteries and lighting sources is increasingly small nowadays.
Thanks for the technological breakthrough in both the lithium-ion battery and LED lighting. These developments make it possible for the solar lighting industry to develop integrated solar street lights.
Compared with lead acid batteries, lithium batteries are lighter, smaller, with longer lifespan and larger DoD, what is more important is that lithium batteries are with larger capacity at the same volume.
2. Light source
Compared with MH/HPS bulbs, LED takes up far less space in the lamps
