Abstract:
A lighting device includes multiple light emitting diode (LED) channels. Each LED channel is connected in parallel to an output rail of a power converter. The power converter may be a buck regulator. Each LED channel may include an LED string of one or more LEDs, a first transistor that is electrically connected between the LED string and ground, a second transistor that is electrically connected between the first transistor and ground, and a current sensing resistor that is electrically connected between the first transistor and the second transistor. This design provides for self-regulation of current across all LED channels when another LED channel is added to or deleted from the lighting device.

Claim (Index 20):
A lighting system, comprising:\n a buck converter that comprises a DC-to-DC power converter configured to step down voltage while stepping up current from an input to an output rail; a plurality of light emitting diode (LED) channels, each of which is connected in parallel to the output rail of the buck converter, and at least one of which comprises an LED string comprising one or more LEDs; and one or more controllers, each of which is electrically connected to the one or more of the LED channels.
