Problems solved by technology
In addition, due to its small internal space and dense components, the heat is more difficult to dissipate. The high temperature generated by the accumulation of heat will further affect the use of the projector, and even shorten its service life, or damage the optical components.
The current optical lens of LED miniature projectors usually uses plastic heat sinks for heat dissipation, but it is necessary to use a large number of plastic heat sinks with a large area to meet the heat dissipation requirements, resulting in a large projector size that cannot meet the miniaturization requirements
In addition, the uneven heat dissipation of the plastic heat sink will affect the use effect of the projector, and it is easy to age and has a short service life.
