Description

Heat dissipation structure of light source module

Technical Field

The utility model relates to the technical field of optical fiber scanner structures, in particular to a heat dissipation structure of a light source module.

Background

The optical fiber scanner is an imaging element of an optical fiber scanning projection technology, drives a scanning optical fiber to perform the motion of a preset two-dimensional scanning track through an actuator, simultaneously modulates the light emitting power of a light source, and projects each pixel point information of an image to be displayed onto an imaging area one by one so as to form a projection picture.

Because the size of the image emitted by a single optical fiber scanner is small, in order to realize large-size imaging, a plurality of optical fiber scanners are often required to form an array, and the images emitted by the optical fiber scanners are spliced with each other. Therefore, in order to enable the splicing quality of the emergent images of the adjacent optical fiber scanners to meet the imaging requirement, such as avoiding the defects of gaps, superposition and the like, the emergent angle of the optical fiber scanner needs to be adjusted.

However, since the size of the optical fiber scanner itself is small, and the distance between adjacent optical fiber scanners in the optical fiber scanners arranged in the array is also small, how to adjust the exit angle of the optical fiber scanner in a small space becomes a technical problem to be solved urgently.

Furthermore, when the optical fiber scanners arranged in the array are in fault and need to be maintained and replaced, the optical fiber scanners need to be connected with the light source and the control device independently, and the photoelectric connecting part is quickly disassembled and assembled, so that the single optical fiber scanner can be replaced quickly, and the technical problem to be solved is also solved.
