Abstract

An information handling system projector lamp door includes a thermal safety latch that secures the lamp cover panel if the temperature of the projector interior exceeds a safety limit associated with potential harm to an end user. A thermostatic spring expands at a predetermined temperature to interfere with movement of a latch so that the latch is locked to secure the cover panel in a closed position. Below the predetermined temperature, the thermostatic spring retracts to allow movement of the latch so that the cover panel is released to move to an open position. An override interfaces with the thermal safety latch to allow manual release of the cover panel by retracting the thermostatic spring.
