Title: ENERGY SOURCE BACKUP CHARGING POWER SUPPLY THAT ADAPTS TO A VARIABLE INPUT VOLTAGE
Abstract:
A power supply that senses the variable voltage on LED devices and uses this voltage to force current into a storage device such as a battery to charge it. When power fails, a DC-DC boost converter supplies the necessary voltage taking current from the battery to maintain the LEDs at percentage nominal current level.
