摘要： A digital micromirror device ('DMD') (320) is used to alter the shape of light that is projected onto a stage (582). The DMD selectively reflects some light, thereby shaping the light that is projected onto the stage. The control for the alteration is controlled by an image. That image can be processed (812), thereby carrying out image processing effects on the shape of the light that is displayed.

摘要： The invention relates to an electronic control system in a lighting device with field programmable gate array. The digital microwave device DMD (600) has thermocouples (602 and 604) on the front and rear sides thereof. The incoming light (610) bounces off the front surface (612) of the DMD and certain amount of this light is converted to heat which travels from the front surface. Cooling element (620) for reducing high temperature built up in the DMD.
