DETAILED DESCRIPTION

[0028] To make the purpose, technical scheme and advantage of the utility model more clear, the following will combine the utility model specific embodiment and corresponding drawing to the utility model technical scheme clear, complete description. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor are within the scope of the utility model protection.

[0029] The terms "first", "second", and the like in the description and claims of the utility model are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, not limited to the number of objects, for example, the first object can be one or more.

[0030] The technical solutions disclosed by the various embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figures 1 to 5 The utility model embodiment discloses a lighting lamp, which can be a ceiling lamp, a spotlight or the like. The lighting lamp can include a housing 110, a light source plate 120 and an end cover 130. The housing 110 is provided with a mounting cavity. The light source plate 120 is arranged in the mounting cavity of the housing 110 and connected to the inner wall of the housing 110. The specific connection mode can include clamping, bolt connection or the like. The light source plate 120 is of a plate structure. The surface of the light source plate 120 is provided with a plurality of light emitting sources, which can include incandescent lamps, halogen lamps, LEDs (Light Emitting Diode) or the like. In addition, the housing 110 is also provided with a light-transmitting part 111. The light-transmitting part 111 is arranged opposite to the light source plate 120, so that the light emitted by the light source plate 120 can be emitted out of the housing 110 through the light-transmitting part 111. The light-transmitting part 111 can be one or a combination of a lens and a light-transmitting panel.

[0032] The side surface of the housing 110 is provided with an opening, so that the light source plate 120, the lens, the light-transmitting panel and the lighting drive and the like can be installed in the housing 110 through the opening. After the installation of the various components in the housing 110 is completed, the end cover 130 is covered on the opening of the side surface of the housing 110 to block the opening, so as to improve the dustproof effect of the lighting lamp and avoid the problem of light leakage of the lighting lamp. When the lighting lamp moves, even if the light source plate 120 is fixed to the housing 110 by clamping, bolt connection or the like, considering that there will be a certain assembly gap between the light source plate 120 and the inner wall of the housing 110, the light source plate 120 will still shake relative to the housing 110, which will lead to the problem of abnormal noise or even damage of the lighting lamp.

[0033] Based on the problem, the structure of the end cover 130 can be improved. Specifically, the end cover 130 can include a cover plate 131 and a limiting structure 132. The cover plate 131 is used to cover the opening on the side surface of the shell 110. The limiting structure 132 is connected to the surface of the cover plate 131 facing the shell 110. The limiting structure 132 can be a buckle, a pressing plate, a clamping groove, or the like. The limiting structure 132 and the cover plate 131 can be an integral structure, or they can be separately manufactured and then assembled together by adhesion, clamping, or the like. When the cover plate 131 is covered on the opening of the shell 110, the limiting structure 132 can extend into the shell 110 through the opening of the shell 110 and limit the cooperation with the light source plate 120. Thus, the light source plate 120 can be pressed against the inner wall of the shell 110, thereby reducing the shaking of the light source plate 120 relative to the shell 110.

[0034] The specific way in which the limiting structure 132 limits the cooperation with the light source plate 120 can include the following: first, the limiting structure 132 is a limiting groove. When the cover plate 131 is covered on the opening of the shell 110, the end of the light source plate 120 can extend into the limiting groove to achieve limiting. In addition, the groove wall of the limiting groove can also exert a certain pressure on the light source plate 120, so that the light source plate 120 can stably contact the inner wall of the shell 110. Second, the limiting structure 132 is a pressing plate. When the cover plate 131 is covered on the opening of the shell 110, the pressing plate extends into the shell 110 and presses the light source plate 120 against the inner wall of the shell 110. Third, the limiting structure 132 is a buckle. Correspondingly, the light source plate 120 is also provided with a cooperating buckle. When the cover plate 131 is covered on the opening of the shell 110, the buckle extends into the shell 110 and is clamped with the cooperating buckle of the light source plate 120 to achieve limiting. In addition, the clamping force between the buckles can also press the light source plate 120 against the inner wall of the shell 110, so that the light source plate 120 can stably contact the inner wall of the shell 110. The above only lists a part of the embodiments for description. As for the specific cooperation mode between the limiting structure 132 and the light source plate 120, as long as the light source plate 120 can be pressed against the inner wall of the shell 110 to reduce the shaking of the light source plate 120, the present application does not limit this.

[0035] It should be noted that the number of openings on the side surface of the shell 110 can be one, two, or more than two. Correspondingly, the number of end covers 130 can also be one, two, or more than two. As shown in FIG. 1, Figure 5 two openings are provided on the shell 110. Then, the end cover 130 described above can be arranged at the two openings.
