LASER PROJECTION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240027885 titled 'LASER PROJECTION APPARATUS
Simplified Explanation
The abstract describes a laser projection apparatus that consists of a laser source assembly, a light modulation assembly, and a projection lens. The laser source assembly includes a laser device with a base plate, at least one frame, and multiple light-emitting chips. An accommodating space is defined between the frame and the base plate. The base plate has a first region and a second region, with the second region located on one side of the first region. The operating parameter of each light-emitting chip in the first region is lower than that of each light-emitting chip in the second region, which can be the photothermal conversion efficiency or the wavelength of the emitted laser beam.
- The laser projection apparatus includes a laser source assembly, a light modulation assembly, and a projection lens.
