Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example one

As shown in fig. 1 and fig. 2, the small panel lamp in the present embodiment includes a lamp housing 1 having a cavity opened downward, a light emitting module disposed in the lamp housing 1, a light guide module 2 disposed in the lamp housing 1, and a diffusion plate 3 covering a portion below the light guide module 2 in correspondence to the opening.

The lamp housing 1 is the lamp housing 1 processed by a galvanized plate through a stamping connection die, so that the speed of the lamp housing 1 is higher than that of a panel manufactured by die casting, and the cost of parts is low. And the lamp housing 1 made of the galvanized sheet can meet the strength requirement of the lamp housing 1, is good in environmental protection, light in weight and can exert a better heat dissipation effect. Meanwhile, during the production of the panel lamp, only the lamp housing 11 needs to be painted and colored, and compared with the problem that the existing shell usually adopts a structure of butting two components, the color difference can occur, the problem can not occur in the lamp housing 1, the appearance is integrated without color difference, and the attractiveness is better.

The edge of the lamp shell 1 is turned outwards in the radial direction to form a flange 11, and a gasket is arranged above the flange 11 in a matching manner. For the sake of aesthetic property, the outer periphery of the turned-over edge 11 is also bent and extended upwards, so that when the turned-over edge 11 is viewed from bottom to top, the edge of the turned-over edge 11 is smoothly transited, and the appearance is more beautiful. The gasket can fill the space between the lamp housing 1 and the ceiling after the panel lamp is installed on the ceiling, and the influence of the unevenness of the ceiling on the installation attractiveness is avoided.

The light emitting module and the light guide module 2 in this embodiment may adopt corresponding structures in the prior art.

The diffuser plate 3 can adopt the high luminousness quality plastics of environmental protection dull and stereotyped, and the thickness of this diffuser plate 3 is specifically selected as required, and inside this diffuser plate 3 can prevent that external debris from entering into lamp body 1, also can exert good light diffusion simultaneously, reached good light transmission effect.

The lower part of the flange 11 is matched with the flange 11 and fixedly provided with an annular cover plate 4, the inner edge of the cover plate 4 upwards extends integrally to form a support plate 41 which is propped against the light guide component 2, and the diffusion plate 3 is limited on the support plate 41.

Specifically, in order to conveniently realize the fixed mounting of the cover plate 4 on the lamp housing 1 and improve the convenience of the assembly of the cover plate 4, the cover plate 4 is further upwardly extended with a connecting plate 42, and the connecting plate 42 is located on the inner side of the supporting plate 41 and is clamped on the side wall of the lamp housing 1. If the diameter of the connecting plate 42 and the diameter of the side wall of the lamp housing 1 can be matched, the connecting plate 42 is tightly fitted on the inner side of the side wall of the lamp housing 1, and then the cover plate 4 is fixedly mounted on the lamp housing 1.

In order to further improve the connection firmness of the cover plate 4 on the lamp housing 1, the inner circumferential surface of the side wall of the lamp housing 1 is circumferentially provided with a first clamping groove 12, and the connecting plate 42 is circumferentially and convexly provided with a convex rib 421 which can be matched with the first clamping groove 12 in a clamping manner. Through the cooperation of the protruding rib 421 and the first clamping groove 12, the reliable connection between the connecting plate 42 and the side wall of the lamp housing 1 is realized, and the installation of the cover plate 4 on the lamp housing 1 is further realized. When the cover plate 4 is mounted, the upper surface of the cover plate 4 is attached to the lower surface of the flange 11, and the top of the support plate 41 is capable of abutting against the lower surface of the light guide member 2.

In order to further improve the third dimension of the shape of the lamp housing 1, and increase the heat dissipation area, and realize the effective support of the light guide assembly 2, the top wall of the lamp housing 1 is at least provided with a concave part 13 in the middle, the light guide assembly 2 is limited between the concave part 13 and the top of the support plate 41, the inner surface of the concave part 13 is a plane, and then the smoothness of the light guide assembly 2 in the lamp housing 1 is ensured on the basis of no additional fixing structure, and the light processing effect is improved.

The inner side surface of the supporting plate 41 is provided with a second clamping groove 411, the edge of the diffusion plate 3 is clamped in the second clamping groove 411, and in order to prevent the path of water vapor from moving upwards in the longitudinal direction of the gap between the second clamping groove 411 and the diffusion plate 3, the upper end edge of the second clamping groove 411 is positioned on the inner side of the lower end edge. The upper end edge of second draw-in groove 411 can block in vertical formation like this, avoids the vertical moving direction of the steam of unexpected entering, and then guarantees panel light's safe in utilization. When adopting this scheme, the interval sets up between diffuser plate 3 and the light guide component 2, so also can increase the route, even trace steam gets into, also can remove the in-process at steam and dry.

The small panel lamp can quickly realize the fixed installation of the diffusion plate 3 by only adding one cover plate 4. And because the supporting plate 41 connected with the cover plate 4 effectively avoids the longitudinal gap between the diffusion plate 3 and the lamp housing 1, the water vapor is effectively prevented from entering the lamp housing 1, the use safety of the panel lamp is ensured, and the service life of the panel lamp is prolonged.

Example two

As shown in fig. 3 and 4, the present embodiment differs from the first embodiment only in that: the diffusion plate 3 is attached to the lower surface of the light guide member 2, and the support plate 41 is supported on the lower surface of the diffusion plate 3. In this structure, there is not vertical clearance between diffuser plate 3 and the backup pad 41, effectively prevents inside steam enters lamp body 1 through vertical route, has effectively guaranteed this panel light's safety in utilization.

Further, the inner peripheral surface of the support plate 41 is provided with a stepped surface 413 in the vertical direction. Not only improves the three-dimensional sense of the panel lamp, makes the panel lamp beautiful, but also plays the role of preventing glare

In order to further exert the effect on the reflector and improve the uniformity and diffusion range of the light emission, the supporting plate 41 is inclined outward from top to bottom in the radial direction.

The small panel lamp can be quickly and fixedly installed on the diffusion plate 3 by only adding the cover plate 4. And because the supporting plate 41 connected on the cover plate 4 effectively avoids the longitudinal gap between the diffusion plate 3 and the lamp housing 1, the water vapor is effectively prevented from entering the lamp housing 1, the use safety of the panel lamp is ensured, and the service life of the panel lamp is prolonged.
