Description

Technical Field

[0001] This utility model relates to the field of wall washer light technology, and in particular to an ultra-thin grille linear light. Background Technology

[0002] Linear lights are a common type of decorative lighting fixture. Their light sources are arranged in a linear strip along a straight line, featuring concentrated light and a regular illumination range, making them widely used in decorative lighting for building facades. To meet the lighting needs of building walls of varying lengths, existing linear lights can be spliced ​​together to achieve installations of any length. When installed on building walls, they create a continuous and uniform wall-washing lighting effect, enhancing the building's appearance and improving its nighttime visual appeal.

[0003] However, existing linear lights, in order to ensure the brightness of wall washer lighting, only use lenses to focus the light, lacking anti-glare structural design. Because the light beam of linear lights is relatively wide, when pedestrians pass near the building wall where linear lights are installed, the light emitted by the light source will directly enter their eyes, producing a strong glare phenomenon. This not only affects visual comfort but may also interfere with people's normal visual judgment, posing a potential safety hazard.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0017] This utility model provides an ultra-thin grille linear light. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0019] Please see Figures 1 to 9 As shown, this utility model provides an ultra-thin grille linear light, including: a lamp body 1, a light source plate 2, a screen-printed glass 3, a grille 4, and two end caps 5; the lamp body 1 has an opening 11 extending along its length direction; the light source plate 2 is disposed inside the lamp body 1, and the light source plate 2 is provided with LED light sources 21 and lenses 22 arranged at intervals along the length direction of the lamp body 1, with each lens 22 corresponding to one of the LED light sources 21; the screen-printed glass 3 is disposed on the opening 11, and the screen-printed glass 3 is provided with a light-transmitting area 31; the grille 4 is disposed between the screen-printed glass 3 and each lens 22, and the grille 4 is provided with a plurality of inclined light-shielding strips 41, each light-shielding strip 41 being arranged at intervals along the width direction of the lamp body 1, and all being inclined along the width direction of the lamp body 1, specifically, the light-shielding strips 41 are inclined toward the illuminated surface of the building wall, and the inclination angle is 68°-85°; the two end caps 5 are respectively disposed at the two ends of the lamp body 1.

[0020] In the above description, the non-transparent area 31 of the screen-printed glass 3 is provided with a black light-shielding layer 32. The width of the light-transmitting area 31 is the same as the width of the lens 22 and equal to the total width of the multiple light-shielding strips 41 laid in the width direction of the lamp body 1. By setting the black light-shielding layer 32, stray light can be blocked, preventing stray light from overflowing from the edge of the opening 11 of the lamp body 1, and effectively preventing stray light from interfering with the uniformity of the wall washing light.

[0021] In use, after the LED light source 21 is powered on and emits light, the light is first focused by the lens 22 to ensure the luminous efficacy of the lamp. When the light shines on the grille 4, the inclined light-shielding strips 41 will specifically block the direct light from the side where the pedestrian is standing (i.e., the side away from the wall), allowing only the light facing the wall to pass through the gaps between the light-shielding strips 41, thus blocking the light that may directly enter the pedestrian's eyes; the wall-side light filtered by the grille 4 finally passes through the light-transmitting area 31 on the silkscreened glass 3, forming a continuous and uniform wall-washing light. Through the above settings, the grille 4 is built into the lamp body 1, so that the grille 4 does not occupy external space, which not only ensures the aesthetic appearance of the lamp, but also adapts to various installation scenarios; and the thin grille 4 can specifically block the light from the standing side, greatly improving the eye comfort of pedestrians when passing near the wall where it is installed, thereby playing a role in preventing glare. Meanwhile, with the light focusing effect of lens 22 and the shielding effect of screened glass 3, the light can be concentrated and evenly covered on the building wall, effectively ensuring the quality of wall washing lighting.

[0022] In a preferred embodiment, see [reference] Figure 2 , 3 The lamp body 1 has two symmetrically arranged mounting slots 12. The grille 4 is embedded in each of the two mounting slots 12 on both sides, providing stable lateral positioning. Two end caps 5 are fixed to the two ends of the lamp body 1. The inner walls of the end caps 5 provide axial positioning for the two end faces of the grille 4, ensuring stable installation of the grille 4 within the lamp body 1 and preventing displacement due to vibration or external force, which would affect the anti-glare effect. Furthermore, the grille 4 is detachably connected to the mounting slots 12. When a different type of grille 4 needs to be replaced, simply remove the end caps 5 at both ends of the lamp body 1, and then pull the grille 4 out of the lamp body 1 along the extension direction of the mounting slots 12. After replacing with a new grille 4, re-embed it in the mounting slots 12 and reinstall the end caps 5. This convenient operation does not damage the main structure of the lamp, improving the flexibility and adaptability of the lamp.

[0023] It should be noted that the total thickness of the grille 4 should be less than the distance between the lens 22 and the screen-printed glass 3 to ensure that the grille 4 can be smoothly inserted into the installation space formed by the lens 22 and the screen-printed glass 3.

[0024] Further, see Figure 2 , 3The lamp body 1 has two symmetrically arranged first circular grooves 13 inside, which are located on both sides of the lens 22, and the mounting groove 12 is located on the side of the first circular groove 13 closest to the lens 22. The end cap 5 is connected to the two first circular grooves 13 by first fastening screws 51. Through the above arrangement, the fixing structure of the end cap 5, the lens 22, and the mounting groove 12 of the grille 4 form a compact arrangement in the width direction of the lamp body 1, effectively reducing the width of the entire lamp. At the same time, the above structure does not interfere with the focusing effect of the lens 22 and the light-shielding effect of the grille 4, and further optimizes the internal space utilization of the lamp body 1 while ensuring that the lighting and anti-glare performance are not affected.

[0025] Preferably, the lamp body 1 is further provided with two symmetrically arranged second circular grooves 17, which are located near the bottom of the lamp body 1; correspondingly, the end cover 5 is provided with four first countersunk holes 52, which correspond one-to-one with the two first circular grooves 13 and the two second circular grooves 17. During installation, the first fastening screw 51 passes through the first countersunk hole 52 and connects to the corresponding circular groove to achieve stable installation of the end cover 5. Through the cooperation of the first countersunk hole 52 and the first fastening screw 51, the nut of the first fastening screw 51 is hidden in the first countersunk hole 52, realizing the hidden installation of the first fastening screw 51, effectively avoiding the first fastening screw 51 from being exposed, preventing the screw from protruding and damaging the neatness of the overall lamp appearance, thereby ensuring the aesthetic appearance of the lamp.

[0026] Preferably, see Figure 4 The lamp body 1 has two symmetrically arranged second slots 18 on both sides; the second slots 18 communicate with the first circular groove 13 and extend along the length of the lamp body 1. A light-shielding baffle 9 can be connected to the second slots 18. The light-shielding baffle 9 has an arc surface and protrudes outwards towards the side where the pedestrian is standing. Users can selectively install the light-shielding baffle 9 according to their actual needs to further improve the anti-glare effect.

[0027] Specifically, the end cap 5 is provided with a shielding piece 53, which corresponds to the position of the second slot 18. The shielding piece 53 is used to shield the first fastening screw 51 on the corresponding first circular groove 13. After the end cap 5 is installed, the shielding piece 53 is precisely embedded in the second slot 18, and the outer surface of the shielding piece 53 is flush with the outer wall of the lamp body 1, which can completely cover and shield the corresponding first fastening screw 51, preventing the screw from being exposed and damaging the appearance of the entire lamp.

[0028] In this embodiment, the grille 4 has two implementation methods: The first implementation method, such as Figure 1 , 3As shown in Figure 5, the grille 4 includes a thin plate 42, which has a plurality of spaced light-transmitting holes 421 along its length. Each light-transmitting hole 421 corresponds to a lens 22. A plurality of light-shielding strips 41 are disposed in each light-transmitting hole 421 to control the light of a single lens 22. Specifically, the light-transmitting area 31 of the screen-printed glass 3 extends along the length of the screen-printed glass 3. The thin plate 42, the light-transmitting holes 421, and the light-shielding strips 41 are integrally stamped from sheet metal. The length and width of the light-transmitting holes 421 correspond to the length and width of the lens 22, so that the stamped light-shielding strips 41 can just cover the light-emitting surface of the lens 22, ensuring effective control of the light emitted from the lens 22. The integral stamping process not only ensures the structural integrity and connection stability of the thin plate 42, the light-transmitting holes 421, and the light-shielding strips 41, but also ensures that the tilt angle of each light-shielding strip 41 is completely consistent, achieving a consistent light control effect.

[0029] Meanwhile, the surface of the thin plate 42 is coated with a black coating, so that the surface of the light-shielding strip 41 is also black. The black coating can absorb light from the direction away from the building wall and directly cut off the propagation path of the light in that direction. On the other hand, it can reduce the light reflection on the surface of the light-shielding strip 41 and prevent the reflected light from forming secondary glare inside the lamp body 1, thereby further enhancing the anti-glare effect of the lamp.

[0030] The second implementation method, such as Figure 7 , 8 As shown in Figures 9 and 1, the grille 4 includes a light-transmitting plate 43, with all the light-shielding strips 41 located on the side of the light-transmitting plate 43 closest to the screen-printed glass 3. Specifically, the light-transmitting areas 31 of the screen-printed glass 3 are arranged at intervals along the length of the screen-printed glass 3, and each light-transmitting area 31 corresponds to a lens 22. The light-transmitting plate 43 is made of white PC (polycarbonate) material, while the multiple light-shielding strips 41 are made of black PC material. The high light-shielding properties of the black PC material ensure effective blocking of light from non-target directions, and its material properties are compatible with the white PC light-transmitting plate 43, forming a strong bond. During the processing of the grille 4, the light-transmitting plate 43 and the multiple light-shielding strips 41 are integrally processed by extrusion molding. The multiple light-shielding strips 41 extend along the length of the light-transmitting plate 43, and the spacing and tilt angle between each light-shielding strip 41 are consistent, thereby ensuring a consistent anti-glare effect in any area of ​​the lamp body 1.

[0031] In a preferred embodiment, see [reference] Figure 2 , 6The system also includes a power connection component 6. A wire groove 14 is provided on the side of the lamp body 1 away from the opening 11. The power connection component 6 includes a housing 61 with several second countersunk holes 611. The housing 61 is fixed within the wire groove 14 by second fastening screws 62 passing through each second countersunk hole 611. A waterproof ring 63 is provided between the housing 61 and the bottom of the lamp body 1. The heads of the second fastening screws 62 are completely hidden within the second countersunk holes 611, not protruding from the surface of the housing 61, achieving an integrated concealment effect between the power connection component 6 and the wire groove 14. Specifically, the power connection assembly 6 further includes several power connection pins 65 and cables 64 electrically connected to the power connection pins 65. The connection positions of the power connection pins 65 and cables 64 are sealed and installed inside the housing 61. The ends of the power connection pins 65 extend outside the housing 61 and pass through a pre-set hole at the bottom of the lamp body 1, and are electrically connected to the pin holder on the light source board 2. The bottom of the housing 61 is provided with an annular groove 612. The power connection pins 65 are located in the area enclosed by the annular groove 612, and the waterproof ring 63 is embedded in the annular groove 612. Under the squeezing action of the housing 61 and the bottom of the lamp body 1, the waterproof ring 63 deforms and forms a tightly fitting sealing structure.

[0032] Preferably, see Figure 2 The end cap 5 and the end of the lamp body 1 are provided with silicone pads 54. When the end cap 5 and the end of the lamp body 1 are fixedly connected, the silicone pads 54 will be squeezed and deformed, thereby tightly filling the gap between the end cap 5 and the end of the lamp body 1, achieving a sealing effect between the two.

[0033] Preferably, see Figure 3 The lamp body 1 has two adhesive grooves 19 located near the opening 11. The screen-printed glass 3 is fixed to the two adhesive grooves 19 by adhesive. By setting the adhesive grooves 19, on the one hand, the assembly contact area between the screen-printed glass 3 and the lamp body 1 is increased, improving its installation stability; on the other hand, the fluidity of the adhesive can completely fill the gap between the screen-printed glass 3 and the side wall of the lamp body 1, forming a continuous and uninterrupted sealing structure. Combined with the above three sealing structures, outdoor rainwater and moisture are effectively prevented from entering the lamp body 1 from the assembly gap, thereby achieving the function of protecting the internal circuit.

[0034] Further, see Figure 2 , 36. The lamp body also includes a decorative panel 7 for concealing the housing 61. The wire groove 14 has two symmetrically arranged first slots 15. The decorative panel 7 has at least two latches 71, each latch 71 engaging with one of the two first slots 15. Specifically, the latches 71 have an approximately triangular cross-section, and the first slots 15 are adapted to the latches 71 to achieve rapid assembly of the decorative panel 7 and the wire groove 14. After the decorative panel 7 is installed with the first slots 15 via the latches 71, it completely conceals the housing 61 within the wire groove 14, making the overall visual effect of the lamp body 1 simpler and more unified, further improving the appearance regularity of the lamp.

[0035] In a preferred embodiment, see [reference] Figure 2 , 6 The system also includes at least two brackets 8. The wire groove 14 has two symmetrically arranged sliding grooves 16. Each bracket 8 includes a slide block 81 and a set screw 82. The slide block 81 is slidably connected to the sliding groove 16 and locked in position by the set screw 82, allowing for flexible adjustment of the bracket 8's fixing point on the lamp body 1 according to installation requirements during actual use. Specifically, the slide block 81 has a third countersunk hole 812. After the set screw 82 passes through the third countersunk hole 812, its end abuts tightly against the bottom of the wire groove 14, forming a reliable locking force. Simultaneously, the head of the set screw 82 can be completely embedded in the third countersunk hole 812, without protruding from the surface of the slide block 81, achieving concealed screw installation and preventing exposed screws from compromising the overall appearance of the lamp.

[0036] The bracket 8 also includes a support leg 83 and an adjusting screw 84. The support leg 83 is installed on the building wall by screws to achieve fixed installation of the lamp. The support leg 83 is connected to the slide 81 by the adjusting screw 84. The adjusting screw 84 is used to lock the installation angle between the support leg 83 and the slide 81, thereby adjusting the installation angle of the lamp body 1 to meet the lighting angle requirements of different walls.

[0037] Furthermore, the slide block 81 has a first clearance notch 811 through which the cable 64 from the power assembly 6 passes. Preferably, the end cover 5 has a second clearance notch 55 through which the cable 64 passes. When multiple ultra-thin grille linear lights are spliced ​​together, the external cables 64 of two adjacent lights can extend into the adjacent wire groove 14 through the second clearance notch 55 of the end cover 5, so that the splicing position of the cables 64 is hidden inside the wire groove 14. This achieves neat storage of the cables 64, avoids the exposed cables 64 from damaging the overall appearance of the lights, and further improves the visual neatness after splicing and installation.
