Description

technical field

[0001] The present invention relates to the field of projection equipment, in particular to a projection equipment. Background technique

[0002] With the continuous development of science and technology, projection devices have been more and more widely used due to their advantages of large screen size and good visual effects.

[0003] figure 1 A schematic structural diagram of a projection device in the prior art is shown, such as figure 1 As shown, the projection device includes a light source module 10 , an optical machine module 20 , and a projection lens 30 . With the improvement of brightness requirements, the light source module 10 generally includes a laser component, such as a blue laser, or a blue laser and a red laser, or three-color lasers. The light source module 10 is where the heat source of the projection device is located, and is usually equipped with air-cooled or liquid-cooled heat dissipation devices. The light beam emitted by the lig...
