AI Technical Summary
Technical Problem
In existing three-color lasers, the laser beams are unevenly distributed, which makes the images displayed on projection devices prone to color distortion, and the optical path design is also complex.
Method used
Alternating arrangement of first and second type light-emitting chips is used to emit lasers of different colors, and they are connected to an external power supply through independent pin groups, which simplifies the optical path design and ensures light uniformity.
Benefits of technology
It achieves uniformity of laser emitted light, simplifies the optical path design of projection equipment, avoids color distortion in images, and does not increase the size of the laser.

Abstract
A laser, comprising: a substrate (100), a plurality of light-emitting chips (200), a plurality of first pin groups (300) and a plurality of second pin groups (600). In the arrangement direction of a row of first-type light-emitting chips (210), a plurality of first-color light chips (211) for emitting first-color light and a plurality of second-color light chips (212) for emitting second-color light may be alternately arranged, so that a plurality of first-color light beams and a plurality of second-color light beams can be uniformly distributed, thereby achieving relatively good uniformity of light emitted by the laser. By means of the arrangement in which the plurality of first-color light chips (211) and the plurality of second-color light chips (212) are alternately arranged, each first-type light-emitting chip (210) can be electrically connected to an external power source through a corresponding first pin group (300), and the plurality of first pin groups (300) can be led out through at least three conductive lead-out sides (P) distributed around the light-emitting chips (200) within a package (800), so as to be electrically connected to the external power source, allowing each first-type light-emitting chip (210) to emit laser light when excited by the external power source.
