DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] Please refer to the attached Figure 1-2 The present embodiment provides an end cap structure 1, which is fixedly connected to both sides of the light-emitting component for side sealing and light emission. The end cap structure 1 includes a first end cap 11 and a second end cap 12, wherein the first end cap 11 is a light-transmitting end cap, the first end cap 11 includes a first cover body 111 and a connecting block 112, and the connecting block 112 is arranged at the lower end of the first cover body 111; the second end cap 12 is a non-light-transmitting end cap, the second end cap 12 includes a second cover body 121 and a connecting groove 122, the connecting groove 122 is arranged at the upper end of the second cover body 121, and the connecting block 112 is embedded and connected to the connecting groove 122.

[0034] The first end cap 11 is made of a transparent resin mixed with a certain proportion of a light diffusing agent, so that the light transmittance and haze of the light-transmitting surface of the first end cap 11 are highly consistent with those of the light-emitting component 2, thereby achieving a light-emitting effect without shadows and uniform light emission. It should be noted that the transparent resin is PC, PVC, PS, PMMA, PET or epoxy resin, etc.

[0035] The second end cap 12 is made of dark resin and coated with a titanium dioxide layer on its surface, so that the second end cap 12 is opaque, ensuring that light is emitted at a certain position and achieving uniform light.

[0036] By adopting the above-mentioned design of the first end cover 11 as a light-transmitting end cover, the brightness of the light transmitted through the end cover is the same as the brightness of the light transmitted through the light-transmitting member, thereby ensuring the consistency of the light output effect, effectively improving the light output efficiency, and ensuring the uniformity of the light effect intensity of the entire lamp.

[0037] In addition, the connection between the first end cover 11 and the second end cover 12 is achieved by embedding the connecting block 112 into the connecting groove 122 to achieve a tight fit between the two. While ensuring the stable connection between the first end cover 11 and the second end cover 12, the structure between the first end cover 11 and the second end cover 12 can also be compact and thin.

[0038] In some embodiments, the second end cap 12 and the first end cap 11 are integrally injection molded. The integral molding adopts an integral injection molding method, and the light-transmitting end cap and the non-light-transmitting end cap are double-injected and integrated into one, which effectively ensures the firmness of the bonding between the two and prevents loosening.

[0039] In some embodiments, the first end cap 11 is provided with a light-transmitting surface 110, and the second end cap 12 is provided with a non-light-transmitting surface 120, and the light-transmitting surface protrudes from the non-light-transmitting surface 120 on the side away from the connection groove 122. Through this arrangement, the light transmitted from the light-transmitting surface 110 will not produce a shadow due to the existence of the second end cap 12, which is conducive to splicing multiple lamps and ensures that there is no shadow in the splicing.

[0040] In some embodiments, the connection block 112 is provided with a groove 1121, and a protrusion 1221 is provided on the inner wall of the connection groove 122 corresponding to the groove 1121. Specifically, four grooves 1121 may be provided, and the protrusions 1221 are provided corresponding to the number of the grooves 1121. By inserting the groove 1121 into the protrusion 1221, the connection between the first end cover 11 and the second end cover 12 is ensured to be tight, the virtual shift phenomenon is avoided, and the stability of the light output position is effectively ensured.

[0041] In some embodiments, the connection block 112 is symmetrically provided with a first connection hole 1122, and the connection groove 122 is provided with a second connection hole 1222 corresponding to the first connection hole 1122, and the first connection hole 1122 and the second connection hole 1222 are fixedly connected by screws. There are two first connection holes 1122. Specifically, the screws pass through the first end cap 11 and the second end cap 12 at the same time to reinforce them twice, thereby fastening the end caps to both sides of the light-emitting component 2 to improve the stability of the linear light structure.

[0042] In addition, since the screw locking part is set at the connection between the first end cover 11 and the second end cover 12, there is no screw in the light-transmitting part of the first end cover 11, and no dark area will be generated when the light passes through the first end cover 11, ensuring a high light output rate. On the other hand, when multiple lights are seamlessly spliced, the splicing is shadow-free, effectively ensuring the light output effect when the line lights are spliced.

[0043] Embodiment 2:

[0044] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the end cover structure 1 of the utility model.

[0045] See also Figure 3-4 In this embodiment, the second cover 121 is provided with drain grooves 1211 on both sides, and the drain grooves 1211 are provided below the connection grooves 122. Specifically, the installation position of the linear light is generally on the exterior wall of an outdoor building, and a horizontal or vertical installation method is adopted. By providing the drain grooves 1211, it is ensured that water can flow in and out of the lamp without water accumulation, thereby increasing the service life of the lamp. Under this premise, the drain grooves 1211 are provided on both sides of the second cover 121, and a side hidden design is adopted, which can effectively avoid light leakage, making the overall appearance more beautiful and fashionable, and the product more upscale.

[0046] In some embodiments, the second cover 121 is further provided with an anti-falling step 1212 for limiting the position of the outlet tail card 213. Among them, an installation cavity 1213 is formed between the anti-falling step 1212 and the leakage groove 1211, and the installation cavity 1213 is used to install the outlet tail card 213. Specifically, by the anti-falling step 1212 and the outlet tail card 213 being arranged to fit together, the phenomenon of the wiring tail card falling off due to violent pulling by workers during the on-site installation and construction of the lamp is effectively prevented, thereby avoiding damage to the lamp and ensuring the durability of the lamp.
