[0036] Reference Figures 1 to 7, is a lighting lamp according to an embodiment of the present invention, comprising a lamp housing 100 and a light-emitting module 500 . The lamp housing 100 includes a mounting plate 200, a light emitting plate 300 and two side frames 400. The mounting plate 200 is respectively provided with first assembly parts 210 at both ends along the width direction of the lamp housing 100. The light emitting plate 300 is opposite to and spaced from the mounting plate 200. The light emitting plate 300 is respectively provided with second assembly parts 310 at both ends along the width direction of the lamp housing 100. The two side frames 400 are respectively located on both sides of the width direction of the lamp housing 100. One end of the two side frames 400 is connected to the two first assembly parts 210 of the mounting plate 200 in a one-to-one manner through the first matching part 410, and the other end of the two side frames 400 is connected to the two second assembly parts 310 of the light emitting plate 300 in a one-to-one manner through the second matching part 420. The mounting plate 200, the light emitting plate 300 and the two side frames 400 enclose a accommodating cavity 110. The light-emitting module 500 is arranged on the lamp housing 100 and is located in the accommodating cavity 110.

[0037] The mounting plate 200, the light emitting plate 300 and the two side frames 400 are produced separately and assembled and connected to form the lamp housing 100. When it is necessary to adjust the production of products with different width specifications, the side frames 400 can be used as universal components. Only mounting plates 200 and light emitting plates 300 of different widths need to be used, and one end of the two side frames 400 is connected to the first assembly parts 210 at both ends of the width direction of the mounting plate 200 through the first matching parts 410, and the other ends of the two side frames 400 are connected to the second assembly parts 310 at both ends of the width direction of the light emitting plate 300 through the second matching parts 420 to assemble the lamp housing 100. Then the light emitting module 500 is installed in the accommodating cavity 110 of the lamp housing 100 without remaking the entire lamp housing 100, thereby reducing production costs and improving the versatility of the components of the lamp housing 100.

[0038] Specifically, in this embodiment, the light-emitting module 500 is an LED light strip, and the light-emitting module 500 is mounted on the mounting plate 200. It is conceivable that in other embodiments, the light-emitting module 500 may also have other structures, for example, the light-emitting module 500 may be an LED lamp bead, a halogen lamp, or an incandescent lamp, etc., and those skilled in the art may adopt a specific structure according to actual needs.

[0039] In this embodiment, the first assembly portion 210 is a first slot extending along the length of the lamp housing 100, and the first mating portion 410 is a first clamping block that is engaged with the first slot. The first clamping block is strip-shaped and extends along the length of the lamp housing 100. The engagement of the first clamping block with the first slot secures the side frame 400 to the mounting plate 200, resulting in a simple and easy-to-implement structure. Furthermore, the strip-shaped first clamping block facilitates secure assembly and attachment of the side frame 400 to the mounting plate 200 at all locations along its length, providing a strong connection between the two.

[0040] Specifically, the first card slot is a through slot. During assembly, the first card block is inserted into the first card slot along the length direction of the first card slot to achieve a snap fit between the two.

[0041] It is conceivable that in other embodiments, the first assembly portion 210 and the first matching portion 410 may also be other structures. For example, the first assembly portion 210 is a threaded hole, and the first matching portion 410 includes a through hole and a screw, and the screw is passed through the through hole and threadedly connected to the threaded hole to lock and assemble the mounting plate 200 and the side frame 400; or the first assembly portion 210 is a magnet, and the second matching portion 420 is an iron block, and the magnet and the iron block are magnetically attracted to each other to realize the assembly and fixation of the mounting plate 200 and the side frame 400; or the first assembly portion 210 is a plate body, and the first matching portion 410 is a plate body, and the two are connected and fixed by gluing.

[0042] In the first embodiment, the second assembly portion 310 is a second slot extending along the length of the lamp housing 100, and the second mating portion 420 is a second clamping block that is engaged with the second slot. The second clamping block is strip-shaped and extends along the length of the lamp housing 100. The engagement of the second clamping block with the second slot secures the side frame 400 to the light output plate 300, resulting in a simple and easy-to-implement structure. Furthermore, the strip-shaped second clamping block facilitates secure assembly and attachment of the side frame 400 to the light output plate 300 at all locations along its length, providing a high degree of joint strength.

[0043] In the second embodiment, the second assembly portion 310 is a plug-in strip portion at both ends of the light emitting plate 300 along the width direction of the lamp housing 100, and the plug-in strip portion extends along the length direction of the lamp housing 100. The second matching portion 420 is a second slot extending along the length direction of the lamp housing 100, and the plug-in strip portion is inserted into the second slot. The above structure realizes the assembly connection between the side frame 400 and the light emitting plate 300, and the structure is simple and the connection is relatively firm. Specifically, during production, after the side frame 400 and the mounting plate 200 are assembled, the light emitting plate 300 can be inserted between the two side frames 400 along the length direction of the lamp housing 100. At this time, the plug-in strip portions on both sides of the light emitting plate 300 are inserted into the second slots of the side frame 400, thereby completing the assembly connection between the two.

[0044] In the embodiment, the mounting plate 200 is provided with a third clamping block 220 at both ends along the width direction of the lamp housing 100. The third clamping block 220 is strip-shaped and extends along the length direction of the lamp housing 100. The side frame 400 is provided with a third clamping slot 430. The third clamping block 220 is clamped in the third clamping slot 430. The third clamping block 220 and the first clamping slot are located on different sides of the mounting plate 200. The provision of the third clamping block 220 and the third clamping slot 430 further improves the assembly strength of the side frame 400 and the mounting plate 200. The third clamping block 220 and the first clamping slot are located on different sides of the mounting plate 200, so that the mounting plate 200 and the side frame 400 can be assembled and fixed in all directions, thereby reducing the risk of shaking between the mounting plate 200 and the side frame 400. Specifically, refer to Figure 3 , the third clamping block 220 is disposed on the left or right side of the mounting plate 200, and the first clamping slot is disposed on the lower side of the mounting plate 200. It is understood that in other embodiments, the third clamping block 220 may also be located on the upper side of the mounting plate 200, and the first clamping slot may be located on the lower side of the mounting plate 200.

[0045] In the embodiment, the light output plate 300 includes a main body 320 and an extension arm 330. One end of the extension arm 330 is connected to the main body 320, and the other end of the extension arm 330 is spaced apart from the main body 320. A second slot is formed between the extension arm 330 and the main body 320. The formation of the second slot between the extension arm 330 and the main body 320 makes the structure of the light output plate 300 relatively simple and has good manufacturability.

[0046] Specifically, the main body 320 and the extending arm 330 are an integrally formed structure, and the second slot can be formed simultaneously when the light output panel 300 is manufactured, thereby simplifying the production process.

[0047] In this embodiment, the extension arm 330 is elastic and located on the side of the main body 320 near the mounting plate 200. The other end of the extension arm 330 is provided with a guide slope 340 for guiding the second clamping block into the second clamping slot. During installation, the mounting plate 200 is first assembled and fixed to one end of the two side frames 400. The light output plate 300 is then moved toward the mounting plate 200. The second clamping block of the side frame 400 abuts the guide slope 340 of the extension arm 330, causing the extension arm 330 to elastically deform, allowing the second clamping block to engage the second clamping slot. The extension arm 330 then returns to its original position and clamps the second clamping block with the main body 320, completing the assembly and fixation of the light output plate 300. This structure helps simplify the assembly process between the light output plate 300 and the side frames 400. The light output plate 300 can be inserted into the second clamping block without being inserted along the length of the lamp housing 100.

[0048] Specifically, the light output plate 300 is made of a transparent plastic material. The plastic itself has a certain degree of elasticity, which also makes the extension arm 330 elastic. The light output plate 300 can be made of polymethyl methacrylate, polycarbonate, polyethylene terephthalate, polypropylene, or polyvinyl chloride, etc. Those skilled in the art can configure it according to actual needs.

[0049] Preferably, the light emitting plate 300 is a diffusion plate, which can reduce the glare of the lighting lamp and make the light output more gentle.

[0050] It is conceivable that in other embodiments, the second assembly part 310 and the second matching part 420 can also be other structures. For example, the second assembly part 310 is a threaded hole, and the second matching part 420 includes a through hole and a screw, and the screw is passed through the through hole and threadedly connected to the threaded hole to lock and assemble the light output plate 300 and the side frame 400; or the second assembly part 310 is a magnet, and the second matching part 420 is an iron block, and the magnet and the iron block are magnetically attracted to realize the assembly and fixation of the light output plate 300 and the side frame 400; or the second assembly part 310 is a plate body, and the second matching part 420 is a plate body, and the two are connected and fixed by gluing; or the second assembly part 310 is a second slot, and the second matching part 420 is a plug-in strip, etc.

[0051] In this embodiment, the light emitting plate 300 and the mounting plate 200 are parallel to each other. A beveled portion 440 is provided on the side of the two side frames 400 that is adjacent to each other. The distance between the two beveled portions 440 at the ends closer to the mounting plate 200 is smaller than the distance between the two beveled portions 440 at the ends farther from the mounting plate 200. The beveled portions 440 are inclined relative to the mounting plate 200 and the light emitting plate 300. The cross-section of the accommodating cavity 110 perpendicular to the length of the lamp housing 100 is trapezoidal. The beveled portions 440 can reflect light to a certain extent, or can be coated with a reflective coating so that a portion of light emitted by the light emitting module 500 is reflected by the beveled portions 440 and emitted through the light emitting plate 300, thereby improving the light utilization efficiency of the light emitting module 500 and enhancing the light output effect of the lamp without increasing the power of the light emitting module 500. Furthermore, the beveled portions 440 are directly formed on a portion of the side frames 400, eliminating the need for an additional reflector, simplifying the structure of the lamp and reducing the number of parts in the lamp housing 100.

[0052] In this embodiment, the width of the side frame 400 decreases along the direction from the mounting plate 200 to the light output plate 300. This structure helps maintain the rectangular shape of the lamp housing 100 while allowing the accommodating cavity 110 to have a trapezoidal cross-section, thereby improving light utilization and creating a clever structure. It also helps improve the overall strength of the side frame 400, mounting plate 200, and light output plate 300.

[0053] Specifically, the cross section of the side frame 400 is approximately triangular.

[0054] In this embodiment, the side frame 400 is provided with splicing holes 450 at both ends of the lamp housing 100 along the length thereof for mounting splicing posts 610. When a longer illumination area is required, two or more lamps can be used. By inserting the splicing posts 610 into the splicing holes 450 at both ends of the lamps along the length thereof, the plurality of lamps can be docked and fixed along the length thereof. This allows for uninterrupted illumination of a longer area, resulting in better lighting effects, uniform light output from different lamps, and a better user experience. Different lamps can also be fixed to each other, providing a better installation and fixation effect.

[0055] Specifically, when the splicing column 610 is installed on the side frame 400, the two are also fixed by screws to improve the connection stability.

[0056] Specifically, the side frame 400 is hollow and forms a splicing hole 450. The splicing holes 450 at both ends of the side frame 400 are interconnected, which is beneficial to reducing the weight of the lighting lamp and saving material costs. In addition, the lamp housing 100 can be cut at any position during production to form lighting lamps of different lengths. The side frame 400 and the mounting plate 200 can both be made in the form of profiles, which have good versatility and low cost.

[0057] In this embodiment, the mounting plate 200 is provided with a splicing groove 230 along the length of the lamp housing 100. The splicing groove 230 is used to insert the splicing strip 620. The splicing groove 230 is provided so that when two or more lighting lamps are spliced along the length, in addition to the side frames 400, the splicing strip 620 can also be inserted into the splicing groove 230, thereby splicing and reinforcing adjacent mounting plates 200 and providing a higher connection strength during splicing.

[0058] Specifically, the splicing strip 620 and the mounting plate 200 may be further fixedly connected by screws.

[0059] It is understandable that the splicing posts 610 and the splicing strips 620 can be bent, for example, into an L-shape, in which case the ends of the lighting lamps along the length direction can be spliced into a corner shape through the splicing posts 610 and the splicing strips 620.

[0060] In this embodiment, the lamp housing 100 further includes two end caps 700, which are removably attached to the lamp housing 100 at both ends along its length and seal the accommodating cavity 110 and the splicing hole 450. When the lamp is used alone, the end caps 700 seal both ends of the accommodating cavity 110 and the splicing hole 450 along their length, preventing mist and dust from entering the accommodating cavity 110 and the splicing hole 450. If the lamps need to be spliced together along their length, the end caps 700 can be removed and the splicing posts 610 can be used to conveniently splice multiple lamps together along their length.

[0061] Specifically, the end cap 700 is mounted to the two side frames 400 by screws, and the end cap 700 has a plug-in block that is inserted into the splicing hole 450, ensuring a secure installation of the end cap 700. It is conceivable that the end cap 700 can also be detachably connected through other structures. For example, the end cap 700 can be mounted to the mounting plate 200 by screws; or the end cap 700 can be detachably mounted to the side frame 400 or the mounting plate 200 by magnetic engagement.

[0062] Specifically, the mounting plate 200 and the side frame 400 are preferably made of profiles to facilitate continuous production.
