Abstract
A projector device includes a housing, an optical modulation element provided in the housing, a lens tube with lenses provided inside, and a heat conducting component. A first side wall of the housing is provided with a through hole. The lens tube is nested in the through hole, and a first end of the lens tube is located in the housing and receives lights emitted from the optical modulation element. A first end of the heat conducting component is disposed on an outer wall of a first end of the lens tube, and a second end of the heat conducting component is connected with the housing.
