Abstract
This application discloses a laser, belonging to the field of optoelectronic technology. The laser includes: a base plate, a frame, multiple light-emitting components, a cover plate, and a light-transmitting sealing layer; the frame surrounds the base plate and forms an accommodating space, and the multiple light-emitting components are all located within the accommodating space and fixed to the base plate; the multiple light-emitting components include multiple rows and columns of light-emitting chips arranged in an array for emitting laser light of at least one color; the frame is plate-shaped, the cover plate is annular, and the upper part of the frame is sealed and fixed to the outer edge region of the cover plate; the light-transmitting sealing layer is sealed and fixed to the inner edge region of the cover plate and covers the opening of the cover plate; wherein, the inner edge region of the cover plate is recessed towards the base plate relative to the outer edge region; there is at least one fold between the inner edge region and the outer edge region, and the fold protrudes away from the base plate or is recessed towards the base plate relative to the inner edge region. This application is used for light emission.
