  • Multiregulator circuit and lamp
    Patent number: 6653789
    Abstract: This invention relates to circuits for operation over a range of voltages, more particularly for a vehicle lamp circuit that provides lighting over a range of voltages. The invention provides a circuit that allows the operation of an LED array lamp over a range of voltage. This is achieved by making use of three-terminal adjustable regulators. One of the three-terminal regulators is configured as a voltage regulator. It regulates the voltage by a connection to a voltage divider. A second three-terminal regulator is connected to the voltage regulator. The second regulator is configured to be a current regulator with the current set by one resistor. This circuit can be further modified with additional adjustable three-terminal regulators to increase in functionality.
