Description

Laser device The application is based on China patent application 202110693475.3 (2021-06-22), the name of which is the divisional application of lasers. Technical Field The application relates to the technical field of photoelectricity, in particular to a laser. Background With the development of photoelectric technology, lasers are widely used. Fig. 1 is a schematic structural diagram of a laser provided in the related art. As shown in fig. 1, the laser 00 includes a base plate 001, an annular frame 002, a plurality of light emitting elements 003, a cover plate 004, a light transmissive sealing layer 005, and a plurality of conductive leads 006. Wherein, the frame 002 and the light emitting components 003 are fixed on the bottom plate 001, and the frame 002 surrounds the light emitting components 003. The apron 004 is annular sheet metal component, and the outward flange welding of apron 004 is in the surface that the bottom plate 001 was kept away from to framework 002, and the edge of printing opacity sealing layer 005 is fixed with the inward flange of apron 004. Fig. 1 shows a frame 002 having a plurality of side walls of uniform thickness, and a plurality of openings in opposite side walls, each of the conductive pins 006 passing through one of the openings and being secured to the frame 002. The light emitting chip in the light emitting component 003 is connected with an external power supply through the conductive pin 106, and then emits laser under the excitation of the external power supply, and the laser is emitted through the light-transmitting sealing layer 005, so that the light emission of the laser 00 is realized. However, in the related art, if the fixing reliability of the conductive pins of the light emitting component is to be improved, the holes of the conductive pins and the frame body need to have enough contact area, so that the wall thickness of the frame body is increased, but the frame body and the bottom plate are usually connected in a welding manner, if the thickness of the frame body is thicker, the bottom plate is subjected to larger stress in the welding process of the two parts, so that deformation is easy to occur, the flatness of the surface to which the light emitting assembly is attached is poor, and finally the light emitting effect of the laser is affected. A technical scheme capable of reducing the assembling difficulty of the laser and guaranteeing the light emitting effect of the laser is needed. Disclosure of Invention The application provides a laser, which can reduce the assembling difficulty of the laser and ensure the light emitting effect of the laser. The laser adopts the following technical scheme: A laser comprises a bottom plate, a frame body, a plurality of luminous components, a cover plate and a light-transmitting sealing layer; The frame body is arranged on the bottom plate in a surrounding mode to form an accommodating space, and the plurality of luminous assemblies are positioned in the accommodating space and fixed on the bottom plate; The frame body is in a thin plate shape, the upper part of the frame body is turned outwards to form a first folded edge, and the first folded edge is fixed with the outer edge area of the cover plate; The light-transmitting sealing layer is fixed with the inner edge area of the cover plate and covers the opening of the cover plate; the lower part of the frame body is folded inwards or outwards to form a second folded edge, and the second folded edge is fixedly connected with the bottom plate. The technical scheme provided by the application has the beneficial effects that at least: In the laser provided by the application, the frame body is in a thin plate shape, and on one hand, the second folded edge at the lower part is fixedly connected with the bottom plate, so that when the relatively thin frame body is welded and fixed with the bottom plate, the relatively thin plate-shaped frame body is easier to absorb the internal stress generated in the welding process and is converted into part of mechanical stress to slightly deform, the internal stress born by the bottom plate is relieved, the probability of deformation of the bottom plate is reduced, and the light emitting effect is further ensured. On the other hand, the frame body is used as a side wall part between the upper cover and the bottom plate, the fixing is realized through the first folded edge at the upper part and the outer edge area of the cover plate, the bearing of the upper cover and the light-transmitting sealing layer can be met, a closed space is formed together with the bottom plate, and a plurality of light-emitting components are accommodated.
