Patent abstract

A fixture for a projection system that includes a lamp, a light valve and a projection lens mainly comprises a lamp frame and an optical engine main body, wherein the lamp frame contains a chamber for containing the optical engine main body. The optical engine main body includes an optical engine seat and an optical engine upper cover. One end of the optical engine seat is connected to the lamp frame while another end thereof is connected to the optical engine upper cover. The optical engine seat is made of a heat-insulating material for preventing the heat of the lamp from conducting to the optical engine upper cover for providing better image quality of the projection system, extending the lifetime of the light valve and the projection lens, reducing the weight and the cost of the whole projection system.
