Abstract
An LED driver is provided. The LED driver has a constant current power source. In some embodiments, the constant current power source is an electrical input configured for connection to a source of power at a constant current. In some embodiments, the source of power is a constant current regulator. The LED driver also includes a switch electrically connected to the constant current power source. The switch has at least two outputs wherein the switch is configured to selectively connect the constant current power source to each of the at least two outputs. The switch is configured to connect each of the at least two outputs for a pre-determined period of time.
