[ detailed description ] embodiments

A flat lamp comprising a housing and a light source 1 provided in the housing, as shown in fig. 1 to 5, the housing being composed of a bottom case 2 and a cover 3 covering an open end of the bottom case 2, wherein:

an accommodating space for accommodating a light source is arranged in the bottom shell 2; a convex edge 21 is arranged on the peripheral wall of the opening end of the bottom shell;

the mask 3 is made of a light-transmitting material and comprises a light-transmitting part 31 and a bottom shell edge 32 arranged on the outer wall of the light-transmitting part 31; the area enclosed by all the bottom cover edges 32 is matched with the area enclosed by the convex edge 21 of the bottom cover 2, so that the bottom cover and the convex edge can fall into the mask; a flange stop 321 capable of preventing the flange 21 from coming off the root of the bottom cover rim 21 is provided on the inner wall of the bottom cover rim 32.

On the one hand, the shell consists of the bottom shell 2 and the face mask 3, and the shell needs fewer parts than the shell consisting of three pieces at the present stage, so the assembly is simpler and more convenient, and the production cost is low; on the other hand, as the mask is made of transparent materials and a frame at the present stage is omitted to support the mask, the light-transmitting surface and the illumination angle of the mask are slightly larger, so that the illumination effect of the flat lamp is improved; in addition, because do not use the frame, the dust just can not enter into the lamp and influence illumination effect like the dull and stereotyped lamp of present stage from the gap between frame and the face guard like this, consequently the utility model discloses a structure is more reasonable, manufacturing cost is lower and illuminating effect is better.

In the present embodiment, a plurality of adhesive columns 311 are provided on the bottom surface around the light-transmitting portion 31 of the mask 3; column holes 211 for the rubber columns 311 at the corresponding positions to pass through are arranged on the convex edge 21 of the bottom case 2; the glue posts 311 penetrate through the corresponding post holes 211 and are hot-pressed at the exposed ends thereof to fix the bottom case 2, so that dust can be further reduced from entering the lamp, and the cover and the bottom case can be more firmly mounted together without screws. During large-scale production, a special hot-pressing fixture can be used for melting all or part of the glue columns on the mask at one time (for example, when a square lamp of a flat lamp is used, all the glue columns on the same side can be melted), the fixture can be taken away within one second, and after the fixture is taken away, the melted glue columns on the side are rapidly cooled and solidified; then the other side or other part of the glue column is ironed.

Light source 1 includes PCB board 11 and establishes LED lamp pearl 12 on this PCB board 11, and the light source can be fixed to the drain pan in modes such as magnetism with magnetism or screw.
