Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a linear light and its housing. Background Technology

[0002] LED linear lights are linear lighting fixtures that use LEDs as their light source. They are typically designed in a long, strip shape, offering high flexibility and adaptability. They can be cut or spliced ​​into different lengths as needed, making them suitable for scenarios requiring continuous lighting.

[0003] To address the different application requirements of various locations, two different structures of LED linear lights have been developed: direct lighting and diffuse lighting. Taking tunnel lighting as an example, tunnel lights use direct lighting, which produces significant glare; therefore, diffuse lighting is mostly used. In contrast, factory, warehouse, and shopping mall lighting requires high luminous efficacy, so direct lighting is generally employed. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide a multifunctional linear tunnel light and lamp housing. The lamp housing integrates two mounting positions with different light emission modes. One mounting position can be selected according to the lighting needs, realizing the integration of two light emission modes in one lamp. The usage is flexible and meets the needs of different application scenarios.

[0005] The technical solution of this utility model is as follows: a lamp housing, including a shell, the shell being a semi-closed structure consisting of a bottom surface, symmetrical sides along the middle of the bottom surface, an open top, and open ends; the bottom surface of the shell has an outwardly protruding protrusion in the middle, the protrusion having a hollow center forming a groove, the groove communicating with the inner cavity of the shell, the bottom surface of the shell on both sides of the protrusion being two symmetrical planar segments, the inner surfaces of the two planar segments having symmetrically arranged slots, and the outer surfaces of the planar segments having guide grooves for guiding bracket mounting bolts; the side surface includes a first inclined surface, a second inclined surface, and a first vertical surface connected between the first and second inclined surfaces, the first inclined surface being connected to the end of the bottom surface of the shell, the inner surface of the second inclined surface having a light source plate mounting slot, the opening of the light source plate mounting slot facing the bottom surface of the shell, the upper groove wall end of the light source plate mounting slot having a baffle, the end of the second inclined surface having a second vertical surface parallel to the first vertical surface, the inner surface of the second vertical surface having a snap-fit ​​groove.

[0006] The slots include two symmetrical slot 1 and two symmetrical slot 2; two symmetrical slot 1 are provided on the two planar segments near the protrusion, and two symmetrical slot 2 are provided on the two planar segments away from the protrusion.

[0007] There are four screw holes on the outside of the housing for fixing the plug. Two screw holes are located on the outer sides of the bottom surface of the housing, and one screw hole is provided on each of the two bevels. The screw holes on the outer side of the two bevels are provided with mounting positions for the tempered glass.

[0008] A multifunctional linear tunnel light includes the aforementioned lamp housing, light source board, reflector, tempered glass, and end cap. When using diffuse indirect lighting, there are two light source boards, each mounted in a mounting slot. There is one reflector, with its bottom surface in contact with the bottom surface of the housing and both ends secured to the outside of the lower groove wall of the mounting slot. When using direct lighting, there is one light source board, placed inside the bottom surface of the housing and fixed with screws in the groove. There are two reflectors, with their upper ends secured to the lower groove of a baffle plate and their lower ends secured to the slot. A diffuser plate is mounted in the mounting groove.

[0009] The lamp body housing is sealed at both ends with waterproof gaskets and plugs.

[0010] One end is fitted with a waterproof screw, through which the DC output terminal of the drive power supply is connected to the light source board; the other end is fitted with a waterproof vent valve.

[0011] The tempered glass is installed at the upper opening of the semi-enclosed structure.

[0012] The semi-enclosed structure has mounting positions for installing tempered glass on both sides of the upper opening, and there are adhesive grooves for accommodating the tempered glass at the mounting positions.

[0013] The bracket is bolted to the guide groove, and the upper surface of the bent horizontal plate on the upper part of the bracket contacts the bottom surface of the guide groove and the bottom surface of the protrusion.

[0014] The bracket is an adjustable bracket, including an upper support plate and a lower support plate. The upper support plate is hinged to the lower support plate by hinge bolts. The lower part of the upper support plate has an elongated arc-shaped hole, and the lower support plate is provided with two bolt fixing holes. The two fixing bolts are inserted into the fixing holes on the lower support plate through the elongated arc-shaped hole.

[0015] The beneficial effects of this utility model are as follows: First, the diffuse indirect lighting produces softer, less glaring light with extremely low glare, reducing visual fatigue and ensuring high safety in tunnel applications. Second, continuous installation of the lights results in excellent illumination with uniform illuminance and no dark spots. Third, the multi-purpose nature of the lamp does not increase material costs, reducing the need for molds and thus lowering overall costs. Attached Figure Description

[0024] Figure 1-2 In this invention, when using diffuse indirect lighting, there are two light source plates 4, each mounted in a mounting slot 207. There is one reflector 3, with its bottom surface in contact with the bottom surface of the housing and both ends secured to the outside of the lower groove wall of the mounting slot 207. On the outer side of the corresponding inclined surfaces 211 on both sides of the upper opening of the housing, there is a screw hole with a mounting position for tempered glass 5, and a groove 501 for accommodating the tempered glass 5. Both ends of the lamp housing 2 are sealed with waterproof gaskets 6 and plugs 7. The plugs 7 are mounted to the screw holes 206 on the outside of the lamp housing 2 with screws 9. The DC output terminal of the drive power supply 10 passes through a waterproof screw 8 and connects to the light source plate 4; a waterproof vent valve is installed on the other plug.

[0025] Figure 3In the design, the outer shell 2 of the lamp body is a semi-closed structure consisting of a bottom surface, symmetrical sides along the middle of the bottom surface, an open top, and open ends. A protruding portion 201 protrudes outward from the middle of the bottom surface of the shell. The center of the protruding portion 201 is hollow, forming a groove that communicates with the inner cavity of the shell. The groove increases structural strength (and also serves as a screw fixing groove for the light source board in direct lighting). The bottom surface of the shell on both sides of the protruding portion 201 consists of two symmetrical planar segments. The inner surfaces of these two planar segments have symmetrically arranged slots, including two symmetrical slot one 202 and two symmetrical slot two 203. Two symmetrical slot one 202 are located on the two planar segments closer to the protruding portion 201, and two symmetrical slot two 203 are located on the two planar segments farther from the protruding portion 201. The planar section has a guide groove 204 on its outer surface for guiding the mounting bolts 101 of the bracket. The bottom surface of the guide groove 204 is flush with the bottom surface of the protrusion 201. The side includes a first inclined surface 209, a second inclined surface 211, and a first vertical surface 210 connecting the first and second inclined surfaces. The first inclined surface 209 is connected to the bottom end of the housing. The inner surface of the second inclined surface 211 has a light source plate mounting slot 207. The opening of the light source plate mounting slot 207 faces the bottom surface of the housing. The upper end of the light source plate mounting slot 207 has a baffle 205. The end of the second inclined surface 211 has a second vertical surface parallel to the first vertical surface. The inner surface of the second vertical surface is a snap-fit ​​groove 208. The tempered glass 5 is bonded to the upper open end of the semi-enclosed structure. There are four screw holes 206 on the outside of the housing. Two screw holes 206 are located on the outer sides of the bottom surface of the housing, and one screw hole is provided on the outside of the second inclined surface 211.

[0026] Figure 4 , 5 In this invention, when direct lighting is used, the light source plate 4 is one piece, which is placed on the inner surface of the bottom of the housing and fixed by screws 41 installed in the groove. There are two reflectors 3, with the upper ends of the two reflectors 3 being stuck in the groove at the bottom of the baffle 205 and the lower ends of the two reflectors 3 being stuck in the slot. The diffuser plate 11 is installed in the snap-fit ​​groove 208.

[0027] Depending on the application scenario, light source boards 4 of varying widths can be selected. When high luminous efficiency is required, the width of the light source board 4 can be [specific width required]. Figure 4 The wide plate shown has its lower end, the reflector 3, secured in slot 203. When the application requires low light efficiency, the width of the light source plate 4 can be adjusted. Figure 5 The narrow plate shown has its lower end, the reflector 3, locked in slot 202.

[0028] Figure 6 , 7In this bracket, bracket 1 is an adjustable bracket, including an upper support plate 105 and a lower support plate 102. The upper support plate 105 has a bent horizontal plate 106 on its upper part. The bent horizontal plate 106 is mounted on the guide groove 204 on the bottom surface of the housing via bracket mounting bolts 101. The lower part of the upper support plate 105 is hinged to the lower support plate 102 via hinge bolts 104. The lower part of the upper support plate 105 has an elongated arc-shaped hole 103. The lower support plate 102 has two bolt fixing holes, and the two fixing bolts are inserted into the bolt fixing holes on the lower support plate 102 through the elongated arc-shaped hole 103. The upper surface of the bent horizontal plate 106 contacts the bottom surface of the guide groove 204 and the bottom surface of the protrusion 201, ensuring the stability of the bracket installation.

[0029] Figure 8 The multi-functional linear tunnel light adopts diffuse reflection indirect lighting, providing uniform, soft, and non-glaring light with low glare, making it safer. The light source plate 4 is located on both sides of the lamp, and a parabolic nano-diffuse reflector (referred to as reflector plate 3) is installed inside the lamp. After being reflected by the reflector plate 3, the light passes through tempered glass 5 and is projected outwards, achieving indirect lighting. The light does not shine directly from the light source to the outside of the lamp, but rather diffuses and is evenly projected outwards, forming indirect lighting. There is no direct light, resulting in softer, non-glaring light with minimal glare. This makes tunnel applications safer, provides uniform illumination, and eliminates dark spots.

[0030] This utility model integrates mounting positions for two light emission methods into the lamp housing, achieving multi-purpose functionality. Depending on the requirements of different application scenarios, diffuse reflection is more suitable when indirect lighting is needed, while direct lighting is more suitable when high luminous efficacy is required. The advantage of diffuse reflection indirect lighting is its soft light output and low glare. Direct lighting also offers the advantage of high luminous efficacy. One mounting position can be selected based on the specific application requirements of different locations.
