Going green is easier than ever. high effficeny solar system to manage your daily lighting requirements both for indoors,outdoors and including street lights.
Renewable Energy Solutions using and lighting power saving solutions using High power LED solar powered light system with energy efficient, lighting provides green energy and saves our money Advantages of solar light systems
1)saves your huge power expense
solar light consists of
4)MCU(AVR) and sensor(photo resistor)
5)Power LED & Driver
1.solar panel: solar panels in general are inefficient around 30%percent expensive component in the system A solar panel is a set of solar photovoltaic modules electrically connected and mounted on a supporting structure
2.charger It is designed to charge battery and to prevent from reverse current
3.Battery Ni-cD battery
4.MCU(AVR) and sensor(photo resistor) MCU with photoresistor: Microcontroller unit to control the brightness of LED automatically by receiving data from external world through sensor, This can be provided its brightest level during peak times of night, and then dimmed to accommodate times of reduced usage,thereby allowing for maximum energy efficiency
5.Power LED and driver Lumileds LUXEON high power LEDs are enabling solid-state lighting solutions that are more efficient,more reliable and long life no heat in the light beam and the ability for digital control, to drive these LED's we need a driver typically a power semiconductor device such as BJT/MOSFET is required. we can control brightness using MCU or with opamps.
