ABSTRACT:
A light projector includes a lamp on an optical axis, energized from a remote source of electrical power and focussing illumination at an image plane. The lamp is disposed within a housing having a fan drawing cooling air into the housing through one or more inlets and expelling air through an outlet vent. A chassis within the housing supports the lamp and the fan. The chassis, including the lamp, fan, and a connector to the remote source of electrically power is removable from the housing. In a preferred embodiment, resilient vibration isolation mounting is provided between the lamp and the chassis and between the fan and the chassis, whereby the lamp is substantially isolated from fan vibration.
