Abstract

The invention discloses a 3D projector, which comprises a support, a circuit board, a laser and a lens, wherein the support is fixed on the circuit board, the lens is accommodated in the support, thelaser is accommodated in the support and electrically connected with the circuit board, and the laser faces the lens. The 3D projector further comprises two metal pieces, wherein each metal piece comprises a first heat dissipation part, a second heat dissipation part and a connecting part for connecting the first heat dissipation part and the second heat dissipation part. The support is provided with a connecting part accommodating groove, the first heat dissipation part is fixed on the outer surface of the support, the connecting part is accommodated in the connecting part accommodating groove, and the second heat dissipation part is fixed on the inner surface of the support. The 3D projector provided by the invention has a good heat dissipation effect and does not influence the quality of emitted light spots.

Description

Technical field [0001] The invention relates to a 3D projector. Background technique [0002] At present, 3D projectors are composed of diffractive optical components, brackets, collimating lenses, lasers, and circuit boards. In order to prevent dust and other debris from entering the 3D projector, thereby affecting the light quality, the bracket, the collimating lens and the circuit board are often formed into a completely enclosed space, and most of the above components are plastic parts, which dissipate heat. The efficiency is poor, and the laser generates a lot of heat when it is energized, and the generated heat cannot be dissipated in time, thereby affecting the quality of the emitted light spot. Summary of the invention [0003] In view of this, the present invention provides a 3D projector that has a good heat dissipation effect and does not affect the quality of the emitted light spot. [0004] A 3D projector. The 3D projector includes a bracket, a circuit board, a laser,...
