Abstract
A driver port that provides selectable output currents based on connections thereto, and a driver including the same, is provided. A plurality of shunt resistors are connected in series between a negative output of a driver and a ground. A driver port having a plurality of connection points is provided, each respective connection point connected to a different connection between two of the plurality of shunt resistors. A load including one or more solid state light sources is capable of being connected between one of the connection points of the driver port and a positive output of the driver.
Claims12
A driver port providing selectable output currents, comprising:
- a plurality of shunt resistors connected in series between a negative output of a driver and a ground;
- a driver port having a plurality of connection points, wherein each respective connection point is connected to a different connection between two of the plurality of shunt resistors;
- wherein a load is capable of being connected between one of the connection points of the driver port and a positive output of the driver.
A method of providing different currents to different loads, comprising:
- providing a plurality of shunt resistors connected in series between a negative output of a driver of one or more solid state light sources and a ground;
- providing a driver port having a plurality of connection points, each respective connection point connected to a different connection between two of the plurality of shunt resistors;
- and
- connecting a load comprising one or more solid state light sources between one of the connection points of the driver port and a positive output of the driver.
