Detailed Implementation
[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] like Figure 1 As shown, this utility model provides an integrated, fully waterproof linear light source, including a housing 1, a light source assembly 2, two side cover plates 3, and a transparent protective plate 4. The transparent protective plate 4 is a rectangular plate. The light source assembly 2 includes a circuit board 21, a plurality of light emitters 211 disposed on the circuit board 21, and a light guide 22 corresponding to the positions of the light emitters 211. The light guide 22 is cylindrical in shape. The housing 1 is an integrated structure with an approximately rectangular receiving cavity 11 inside. The peripheral wall of the housing 1 is also provided with light-emitting holes 12 communicating with the receiving cavity 11 and two mounting holes 13. The light-emitting holes 12 are located on the top of the housing 1 and also serve as... On the light-emitting side of the light source, light is emitted from the receiving cavity 11 and passes through the light-emitting hole 12. Two mounting holes 13 are provided on both sides of the housing and are connected through the receiving cavity 11. Because the housing 1 is an integral structure, additional holes need to be drilled to install internal components. The function of the mounting holes 13 is to install the circuit board 21 and the light guide 22 in the light source assembly 2. That is, the circuit board 21 and the light guide 22 are set in the receiving cavity 11. The transparent protective plate 4 and the side cover plate 3 respectively seal and cover the light-emitting hole 12 and the mounting hole 13. This structural design ensures the airtightness of the housing 1.
[0028] The typical manufacturing process for waterproof line light sources involves assembling the housing and components first, then sealing the assembly gaps on the outer surface of the line light source with glue. However, existing waterproof line light sources on the market usually consist of several housings surrounding the circuit board and light guide, resulting in numerous gaps after assembly. This makes applying glue difficult during waterproofing, hindering the assurance of a tight seal and a good appearance. The integrated housing 1 of this application reduces the number of housings required, indirectly reducing the number of external gaps in the light source and the workload of waterproofing operations. This significantly enhances the sealing and waterproofing performance of the waterproof line light source, while also providing a more aesthetically pleasing and unified appearance.
[0029] Specifically, in an example of the utility model, the main light emitting core of waterproof line light source is the plurality of light emitting bodies 211 embedded on the circuit board 21, the material of the transparent protective plate 4 and the light guide body 22 is acrylic, so the transparent protective plate 4 is acrylic plate, the light guide body 22 is acrylic rod, and the acrylic rod has the function of uniformly diffusing the point or linear light emitted by the light source into continuous linear light by using its high light transmission and light scattering properties, avoiding light spot or uneven brightness, that is, the light emitted by the light emitting body 211 is diffused through the light guide body 22 and then irradiated outward through the transparent protective plate 4, and meanwhile, the acrylic material has excellent corrosion resistance and ultraviolet resistance, is suitable for humid, high-temperature or outdoor environment, and can simultaneously realize light transmission, protection and environmental adaptability.
[0030] In another embodiment, the light guide body 22 has a square or flat plate structure, compared with the square or flat plate structure, the curved surface of the cylindrical light guide body 22 causes refraction of light when it is emitted, and the scattering angle is wider, while the light is easy to propagate along a straight line when the square or flat plate structure is adopted, the scattering angle is limited, which may result in sharp edges of light spot and poor uniformity.
[0031] Specifically, in an example of the utility model, the shell 1 is provided with a mounting groove 14 matched with the transparent protective plate 4 on the peripheral wall, and the light emitting hole 12 is arranged in the mounting groove 14, which has the advantages that on the one hand, the transparent protective plate 4 can be more stably embedded in the mounting groove 14 on the peripheral wall of the shell 1 and is not easy to loosen, avoiding falling off of the transparent protective plate 4, and on the other hand, waterproof measures can be taken in the gap between the transparent protective plate 4 and the mounting groove 14, that is, glue is applied, to strengthen the sealing property of the shell 1.
[0032] Specifically, in an example of the utility model, in addition to the transparent protective plate 4 covering the light emitting hole 12 on the top of the shell 1, a cover plate 5 covering the transparent protective plate 4 is further arranged on the top, a rectangular through hole 51 is arranged in the middle of the cover plate 5, and the structure design of the cover plate 5 further strengthens the sealing property of the shell 1, and meanwhile, the through hole 51 in the middle of the cover plate 5 does not affect the light transmission of the light emitting hole 12, in addition, four screw holes are further arranged on the cover plate 5, and corresponding screw holes are arranged on the peripheral wall of the shell 1, so that a screw can be embedded to further fix the cover plate 5 on the peripheral wall of the shell 1, to ensure the sealing property.
[0033] Further, the area range of the through hole 51 is arranged in the area range of the transparent protective plate 4, the through hole 51 and the transparent protective plate 4 are both rectangular in shape, and the length and width of the through hole 51 are smaller than those of the transparent protective plate 4; this structural design enables the gap between the two rectangles to be coated with glue for waterproofing, further enhancing the sealing performance of the light-emitting hole 12, so that the light-emitting hole 12 has the triple waterproof sealing measures of the transparent protective plate 4, the cover plate 5 and the through hole 51, almost eliminating the water from the light-emitting hole 12 into the containing cavity 11 inside the shell 1, while not affecting the normal lighting of the light source.
[0034] Further, the material of the cover plate 5 is aluminum, and aluminum is selected because, first, aluminum has low density, can reduce the overall weight of the light source, has high strength and is not easy to deform, and enhances the sealing performance; second, aluminum has excellent heat conduction performance, can conduct the heat generated by the light source to the outside, avoids the internal temperature from rising too high to affect the service life of the light source, and finally, the aluminum surface generates a dense aluminum oxide protective film, is resistant to moisture, and is very suitable for the humid use environment of the waterproof linear light source.
[0035] Specifically, in an example of the utility model, a sealing ring 311 is arranged between the shell 1 and the side cover plate 3, the material of the sealing ring 311 is elastic silica gel, the shape is an approximately rectangular ring, and the annular range of the sealing ring 311 covers the range of the mounting hole 13 of the shell 1; this structural design enables the sealing ring 311 to fill the gap between components through elastic deformation, blocks the external moisture, dust or pollutants from entering the mounting hole 13 and the containing cavity 11 inside from the gap between the side cover plate 3 and the mounting hole 13, and at the same time, the elasticity of the sealing ring 311 can compensate for the gap change caused by material expansion / contraction when the temperature difference or air pressure changes, thereby maintaining the sealing effect.
[0036] Further, the shell 1 and the side cover plate 3 are provided with a sealing groove 15 corresponding to the sealing ring 311 on one side, and the sealing groove 15 of the two encloses and fixes the sealing ring 311, wherein the space size of the sealing groove 15 is slightly smaller than the size of the sealing ring 311; this design enables the sealing ring 14 to be stably embedded in the sealing groove 15 on the one hand, and to further extrude the generated gap by using the elasticity of the sealing ring 14 on the other hand, thereby forming an excess sealing design and further enhancing the sealing performance.
[0037] Specifically, in an example of the utility model, the bottom of the shell 1 is further provided with a U-shaped connecting cavity 6, a plurality of heat dissipation grooves 61 are arranged in the connecting cavity 6, the surface area of the bottom of the shell 1 can be increased by the structure design, the heat generated by the circuit board 21 can be dissipated faster, the service life of the light source is prolonged, meanwhile, the heat dissipation grooves 61 make the installation of the light source more convenient.
[0038] Further, the connecting cavity 6 is further provided with a waterproof air permeable valve 62 communicated with the accommodating cavity 11, the waterproof air permeable valve 62 can balance the air pressure inside and outside, because the use environment of the waterproof light source is usually humid or even in water, the air pressure difference between the inside and outside of the shell 1 can damage the internal components and deform the sealing ring 311 when used in water, the waterproof air permeable valve 62 communicates the outside with the accommodating cavity 11, so that the air pressure inside and outside the shell 1 is consistent, meanwhile, the waterproof air permeable valve 62 is provided with a microporous membrane, the microporous membrane allows air to flow slowly, automatically balances the air pressure inside and outside, eliminates the damage of the pressure difference to the structure, meanwhile, maintains waterproofness, in addition, the air pressure balance reduces the frequent deformation of the sealing ring, delays material aging, prolongs the service life of the sealing system.
[0039] The working principle of the utility model is described in detail as follows:
[0040] A plurality of light emitting bodies 211 on the circuit board 21 emit point or linear light after being electrified, the light is uniformly diffused through the high-transmittance material (such as acrylic) of the light guide body 22, forming continuous linear light, eliminating the problem of light spot or uneven brightness, the curved surface design (such as cylindrical shape) of the light guide body 22 further expands the light scattering angle, ensuring that the light uniformly covers the target area, the diffused light penetrates the transparent protective plate 4 and projects outward, the integrated structure of the shell 1 greatly reduces the assembly gap, the elastic cooperation of the sealing ring 311 and the sealing groove 15 effectively blocks the intrusion of external moisture, the waterproof air permeable valve 62 balances the air pressure difference between the inside and outside of the shell through the microporous membrane, avoiding the deformation of the sealing ring or the damage of the structure caused by temperature difference or water pressure, while maintaining waterproof performance, the through hole design between the cover plate 5 and the transparent protective plate 4 and the glue filling form multiple sealing layers, further strengthening the waterproof reliability of the light emitting hole, in addition, the heat dissipation grooves 61 at the bottom of the shell 1 increase the heat dissipation surface area, cooperating with the excellent heat conductivity of the aluminum cover plate, quickly conducting the heat generated by the circuit board, prolonging the service life of the light source, the overall design realizes complete waterproofness, while taking into account the light efficiency, heat dissipation and structural stability.
