Problems solved by technology

Lenses are generally divided into two types: glass and plastic. The lenses of both materials have their own advantages and disadvantages. The weight of plastic lenses is relatively small, but the thermal conductivity of plastic materials is poor, and plastic lenses are prone to deformation after being heated. If the heat emitted during the working process cannot be discharged in time, it will cause the deformation of the plastic lens, which will affect the imaging effect of the projection optical machine equipment

Abstract

The invention discloses a light machine board and a projection light machine. The light machine plate is applied to a projection light machine, and comprises a metal plate which is provided with a first surface and a second surface which are arranged back to back; the baffle part is arranged on the first surface, and the baffle part is arranged on a light path when the projection light machine is in a dark state; and the heat conducting sheet is arranged on the first surface and / or the second surface. The heat-conducting fins are arranged on the first surface and / or the second surface of the metal plate, and the internal temperature of the optical machine and the temperature of the baffle part are reduced through the heat-conducting fins.

Description

technical field [0001] The present application relates to the technical field of optical equipment, and more particularly, to an opto-mechanical board and a projector opto-mechanical. Background technique [0002] The Digital Light Processing (DLP) projector display mode has the characteristics of high brightness, high contrast and high resolution. Combined with the new LED light source, it can realize miniaturized portable micro-projection, which is popular with more and more users. welcome. [0003] The beam adjustment module inside the projector includes various lens combinations. Lenses are generally divided into two types: glass and plastic. Both materials have their own advantages and disadvantages. The plastic lens is lighter in weight, but the plastic material has poor thermal conductivity, and the plastic lens is easily deformed after being heated. , If the heat dissipated in the working process cannot be drained in time, it will cause the plastic lens to deform, ...
