Abstract: A no load detection and shutdown circuit in an isolated driver is provided. A no load condition is detected by primary side evaluation of a reflected voltage. If a determination is made that a no load condition is present, the no load detection circuit signals a half bridge driver of the driver to cease oscillations, shutting down the driver.

Abstract: An inverter for a lighting device including one or more solid state light sources is used to power a secondary load, such as a cooling device, sensor, or control with an auxiliary power circuit that provides a selectable auxiliary voltage to the secondary load. The auxiliary power circuit includes a voltage regulation circuit and a voltage selection circuit. The voltage selection circuit provides a feedback voltage to the voltage regulation circuit which his indicative of auxiliary output voltage. The voltage regulation circuit operates based on the feedback voltage and a reference voltage to adjust the auxiliary voltage to a level that differs from the input voltage from the inverter.

Abstract: A multi-strike ballast to ignite an electrodeless lamp is disclosed, and includes an inverter circuit, a protection circuit, and a controller. The inverter circuit, upon activation, sends an ignition pulse to the lamp. The inverter circuit shuts down upon receiving a deactivation signal, and activates upon receiving an activation signal, triggering another ignition pulse. The protection circuit senses a change in a voltage associated with the lamp. The sensed changed may indicate that the lamp has not yet ignited or that the lamp is broken. The controller receives the sensed change in voltage and, in response, sends a deactivation signal to the inverter circuit. The controller waits a predetermined time and then sends an activation signal to the inverter circuit. The controller repeats until a change in voltage associated with the lamp is not sensed, or until a predefined number of repeats occur, providing multiple ignition pulses to the lamp.
