Abstract
An arc lamp lightsource module comprises a removable lamp unit including an arc lamp attached to two radial electrode heatsinks that are in turn disposed in an insulating sleeve housing. A chassis has a catch and a clip to lock down the removable lamp unit. An igniter is included to power the arc lamp. A single fan and an air plenum are disposed in the chassis and provide for a cooling airflow that is split between the igniter and the two radial electrode heatsinks. A pair of machine screws provide electrical contact to each of the two radial electrode heatsinks and that have crowned heads for a smooth contact surface. A printed circuit board (PCB) has springboard cutouts and electrical pads providing for a spring-pressure electrical contact between the igniter and the arc lamp through the pair of machine screws. An electrical interlock switch is mounted to a corresponding springboard cutout on the PCB and provides for an interruption of electrical power from the igniter when the removable lamp unit is removed from the chassis. A pair of fulcrum knobs are provided on one side of the removable lamp unit and provide for a rolling action of the housing to assist a user in removing the removable lamp unit from the chassis.
