  • Patent number: 7682029
    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.

  • Patent number: RE41726
    Abstract: A multiparameter light typically includes a lamp and shutter in combination with one or more optical components, various electrical and mechanical components for operating the optical components, suitable electronics for controlling the parameters of the multiparameter light, and suitable power supplies for the lamp, motors, and electronics. Typically, the lamp is enclosed by the lamp housing, which also contains the other optical components and many of the electrical and mechanical components which operate them. As the lamp and the various components within the lamp housing generate a great deal of heat and as components within the multiparameter light can overheat as a result of various orientations and light makeup parameters, the temperature of components within the lamp housing is managed by controlling the amount of power furnished to the lamp or the amount of light transmitted through the shutter in accordance with the orientation of the multiparameter light and/or the light makeup parameter in use.
