Abstract
The present invention is directed to an LED light system that comprises a control circuit that operates on a pair of 1.5 volt batteries but which generates an operational voltage in excess of 3.0 volts. The lighting system includes a boost circuit that raises the operational voltage of the system to 5.0 volts, and an output circuit connected to a plurality of LEDs that controls their function.
Claims3
1) A lighting control circuit comprising:
- a boosting circuit, said boosting circuit comprising a first integrated circuit and two 1.5 volt batteries;
- and
- an output circuit connected to said boosting circuit, said output circuit comprising a second integrated circuit for controlling an LED lighting load, wherein when said D.C. power supply produces an input voltage of 3.0 volts, said first integrated circuit converts said input voltage to an operational voltage 5.0 volts and transmits said operational voltage to said second integrated circuit wherein said operational voltage is selectively transmitted to said LED lighting load.
