Abstract

The invention provides a projection device and a projection system, which relate to the field of projection technology and are used to solve the problem of uneven temperature distribution on a light source housing of the projection device in the related art. The projection device includes a light source, a radiator, a heat conduction member, a first heat pipe, and a second heat pipe; the heat conduction member includes a heat conduction portion, and the heat conduction portion is in contact with the light source; the first end of the first heat pipe and the first end of the second heat pipe are both The second end of the first heat pipe and the second end of the second heat pipe are respectively connected to the heat conduction member from opposite sides of the heat conduction part. The invention can be used in projection equipment such as laser projectors.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a projection device and a projection system. Background technique [0002] Laser projection equipment is a kind of projection equipment, which uses a laser as a light source. When working, the laser beam generated by the laser is projected onto the screen through the optical system, optical machine and lens to form a projection screen. The laser will generate a lot of heat energy when it is working. In order to ensure the normal operation of the laser, a cooling device is usually installed inside the projection device to dissipate heat from the laser, so as to ensure the luminous efficiency, reliability and life of the laser. Contents of the invention [0003] Embodiments of the present invention provide a projection device and a projection system, which are used to solve the problem of uneven temperature distribution on the light source housing of the projection device in ...
