LED Solar Street Light
Light Emitting Diode (LED) is a device which emits light when an electric current passes through it. A LED based solar street lighting system aims at providing solar electricity for operating LED for dusk to dawn operation per day.
The broad performance specifications of a white Light Emitting Diode (W-LED) light source based solar street lighting systems are given below.
