Instapower offer quality solar street lighting system based on LED technology. In these street lights, the light source is Light Emitting Diode and light output is white color, peak intensity 58 lux in model 1 and 78 lux
in model 2 when measured from a height of 10 ft and illuminated over an area of at least 70 sq. ft.
Our solar street lighting system utilizes high quality LEDs imported from Agilent (USA) , Nichia (Japan) .
The average duty cycle is dusk to dawn and autonomy is 4 days.
The light source is housed in a water resistant assembly and multiple LEDs can be used. The light output from the light source is kept constant. There is no linear variation with changes in the input battery voltage, i.e. 10.5 V DC-13.5 V DC.
SMF battery is used, which has a life of 2-3 years. 75 % of the rated capacity of the battery should be between fully charged & load cut off conditions.
Duty Cycle:
The LED street lighting system is designed to be automatically switch ON at dusk, operate throughout the night and automatically switch OFF at the dawn. It is under the average daily insolation of 5 KWh /sq.m. on a horizontal surface.
