We have established ourselves as a leading name of superior quality 9 W Solar LED Street Light. These are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure or integrated into the pole itself. The photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. These lights turn on and turn off automatically by sensing outdoor light using a light source. Solar streetlights are designed to work throughout the night.
Automatic turn off and on
Photo voltaic panels
Raised light sources
Micro controller based PWM charging with inbuilt solar led street light with the following features:
Constant Current Phase: all charging current available is used to charge a battery.
Constant voltage Phase: Constant battery voltage towards end charge to present excessive gassing
Float Stage (below gassing voltage to avoid electrolyte loss)
Constant Current driver. Driver efficiency > 90%
Reverse polarity protection without the use of fuse to ease up installation in spite of human error
Battery charge indicator for different levels of the battery should be present on the fixture, indicating at least 4 levels of battery for easier maintenance. Apart from this, low battery and charging indicators should also be present
Parallel backup LED pads with each LED should be present so as to replace the solar LED luminary easily in case one of them fails in future
