    Abstract: A ballast to energize a lamp at a selected lighting level is provided. The ballast includes a rectifier, a buck converter, and a controller. The rectifier produces a DC voltage with a substantially constant magnitude. The buck converter generates a lamp voltage output from the DC voltage based on a duty cycle. The output has a magnitude that is varied based on the duty cycle to energize the lamp at a selected lighting level. The controller receives a dim input signal indicating the selected lighting level, and provides an appropriate control signal to the buck converter. The appropriate control signal indicates a particular duty cycle corresponding to magnitude of the output to produce the selected lighting level. In response to receiving the control signal, the buck converter adjusts the duty cycle accordingly, producing the output having the magnitude to energize the lamp at the selected lighting level.

    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.

    Abstract: A electrodeless lamp including a fluorescent discharge vessel, a tip, an amalgam, a lamp core, and a heater. The vessel contains a gas having a partial vapor pressure and a fluorescent material. The tip has an inner end engaging the vessel, and an opening in communication with the gas. The amalgam is positioned within the opening, in heat transfer relation with the tip. When the temperature of the amalgam decreases, mercury vapor in the gas condensates onto the amalgam, causing a decrease in the partial vapor pressure of the gas. The opposite occurs when the amalgam temperature increases. The lamp core generates a magnetic flux, causing an electrical discharge in the gas. The heater includes a positive temperature coefficient connected to a winding of the lamp core. The heater is in heat transfer relation with the tip and heats the tip when the electrodeless lamp is in a dimming mode.
