Abstract
A projection equipment may including a housing arranged with a first opening and a DMD circuit board arranged with a DMD chip on a side facing the housing, where the DMD chip is arranged with an operational region and a non-operational region. The non-operational region may be located in the periphery of the operational region, and the operational region may modulate a portion of a beam that passes through the first opening when the portion of the beam irradiates onto the operational region. A first heat dissipation member may be arranged between the DMD chip and the housing such that there is a space between the first heat dissipation member and the DMD chip. The first heat dissipation member may be arranged with a second opening which provides a passage for the portion of the beam, while blocking the other portion of the beam.
