Projection equipment

Abstract

The invention provides projection equipment. The projection equipment comprises a lens assembly, a lens base, a heat transfer assembly and a cooling assembly, wherein the lens assembly comprises a lens cylinder, the cooling assembly sleeves an outer side of the lens cylinder and is connected with the lens base, the heat transfer assembly is arranged on an outer wall of the lens cylinder and is elastically connected with the cooling assembly, and heat of the lens assembly is conducted to the cooling assembly. By the projection equipment, effective cooling during working can be achieved.

Description

technical field [0001] The present invention relates to the field of projection display, in particular to a projection device. Background technique [0002] With the development of science and technology and the improvement of people's living standards, various projection equipment such as laser TVs and projectors have been widely used because of their advantages of larger projected image size and better display effect. [0003] At present, projection equipment mainly includes optical components and lenses and other components. Among them, optical components are also called optical engines, which usually include galvanometers and other components, which are mainly used to emit light; and the lens usually includes multiple groups of lenses, which can refract light through the combination of lenses inside the lens, so that the imaging. The lens of the lens is installed in a lens barrel made of plastic and other materials, and one end of the lens barrel is connected to the op...

Problems solved by technology

[0004] However, when the projection equipment is working, a certain amount of heat will be generated when the light passes through the lens. When the heat accumulates on the lens, it is easy to deform the lens, and then change the refractive index of each part of the lens, resulting in "temperature drift" phenomenon , affecting the final image
