Description

Technical Field

[0001] This invention relates to the field of ceiling light technology, and more particularly to a suspended ceiling light. Background Technology

[0002] Currently, LED ceiling lights are widely used in various scenarios such as home decoration, office, and commercial lighting, and are the mainstream product in the lighting field. However, the ceiling light industry at present generally suffers from many pain points, such as high difficulty in research and development and production, poor product structural reliability, unsatisfactory optical experience, and severe market competition, which restrict product quality upgrades and the healthy development of enterprises.

[0003] On the R&D and production side, traditional ceiling lights mostly have custom-made structures with dedicated molds. The entire unit and accessories rely on special injection molding and die-casting molds, which results in high mold costs, long R&D cycles, and slow model iteration. For small-batch customization and scenario-based model modification needs, traditional mold-based production has high investment costs and extremely low cost-effectiveness, which can easily lead to idle molds, stockpiled finished products, and continuously increasing inventory pressure. It cannot adapt to the current development trend of lightweight, rapid iteration, and small-batch customization in the lighting market.

[0004] In terms of product structure and assembly, existing traditional ceiling lights generally adopt an assembly mode of "first fixing the whole machine to the wall, then snapping on the diffuser plate." The diffuser plate relies solely on simple clips for connection and is fixed by its own weight, resulting in a loose assembly structure. After long-term use, problems such as loosening, displacement, and abnormal noise are prone to occur. At the same time, the gaps in the clip assembly are relatively large, and the whole machine cannot achieve a complete seal. Dust and insects can easily enter the lamp body through the gaps, which not only affects the light transmission effect and cleanliness of the lamp, but also causes internal components to become damp, oxidized, and aged, significantly shortening the lifespan of the lamp. More importantly, the diffuser plate is easy to disassemble and assemble, but its fixation reliability is poor. There is a risk of accidental disassembly during daily use and maintenance, and the exposed live structure can easily cause electric shock hazards, resulting in a low product safety factor. In addition, traditional ceiling lights are mostly flat and attached to the ceiling, with a relatively simple shape and no three-dimensional sense. The industry suffers from serious homogenization of appearance, making it difficult to adapt to the aesthetic needs of modern home decoration and commercial spaces. Moreover, the overall assembly process is cumbersome, labor costs are high, and the after-sales failure rate remains high.

[0005] In terms of optical performance, the optical designs of current mainstream ceiling lights generally have technical shortcomings, making it difficult to simultaneously meet the requirements of ultra-thin body, high light transmittance, anti-glare, and uniform light distribution. Currently, traditional ceiling lights suffer from noticeable graininess in LED light sources, glare from direct frontal illumination, dark areas in the center of the fixture, blind spots at the edges of the panel, harsh transitions between light and shadow, obvious visual breaks in the luminous surface, and poor overall light uniformity. Some high-end lamps rely on multiple layers of optical plates / films to achieve uniform light and anti-glare effects, which not only complicates the structure and assembly but also increases the overall thickness and production cost, contradicting the current trend of ultra-thin, lightweight, and cost-effective ceiling lights. Furthermore, conventional optical improvement solutions on the market only optimize the luminous effect without integrating optimization with the overall structure, sealing performance, and safety features of the lamp, leaving room for improvement in user experience and reliability.

[0006] Chinese patent CN120274247A discloses a self-developed pitched ceiling light with adjustable light emission angle. The light source includes a ceiling light body, which comprises a top fixing system, a suspension and support system, and a light-emitting component. The light-emitting component emits light diffusely and is concealed, featuring an anti-glare design. The ceiling light body integrates a control module, which is paired with a mobile app for remote brightness adjustment. The module supports 0-100% linear dimming, a color temperature of 2700K-5600K, preset "reading," "movie watching," and "night light" scene modes, and supports timed on / off switching and adaptive light sensor adjustment.

[0007] The above invention has the following problems in its implementation: the light source module 7 is hidden inside the aluminum ring 5, the spacing between the light sources in the light source module 7 is 15-20mm, and the distance between the light-emitting surface of the light source module 7 and the diffuser plate 6 forms a light-shielding angle of ≥30°. Combined with the diffuse reflection of the diffuser plate 6, the surface brightness of the lamp is ≤1000cd / m². 2 It meets the CIE anti-glare standard; however, the anti-glare effect of the light source only meets the CIE anti-glare standard, and the anti-glare effect of the light source needs to be greatly improved.

[0008] Chinese Patent CN219177591U discloses an ultra-thin, three-proof ceiling light, including a lamp housing. A mounting base is screwed to the top of the lamp housing, and several screw-on blocks are provided on the outer side of the mounting base. The top of the lamp housing has screw-on grooves corresponding to the screw-on blocks. Several elongated mounting holes are provided on the top of the mounting base. An LED light strip emitting light inwards is installed on the inner wall of the lamp housing. A reflector, a light-transmitting plate, and a light-diffusing plate are sequentially installed on the inner side of the lamp housing from top to bottom. The light-transmitting plate is located inside the LED light strip. A face ring that abuts against the light-diffusing plate is snapped onto the bottom of the lamp housing. This invention features a simple assembly and installation structure, easy adjustment of the installation position, quick and convenient installation, low manufacturing cost, simple assembly structure (no screws required), short assembly time for components, high production efficiency, good anti-glare performance, and good lighting effect, facilitating the mass production and promotion of ceiling lights.

[0009] The above invention has the following problems in implementation: it requires multiple optical plates / films to achieve uniform light and anti-glare effects, the structure is relatively complex, the assembly is relatively cumbersome, and the final anti-glare effect is also very limited, failing to meet the requirements of anti-glare and uniform light across the entire area.

Example 2

[0036] like Figure 1-6 As shown, a suspended ceiling light includes a base 1, a frame 2, a diffuser plate 3, an LED light source 4, a power supply 5, and a mounting plate 6.

[0037] The chassis 1 includes a panel 101, an annular mounting plate 102 fixedly disposed on the upper end of the panel 101, and an annular baffle 103 fixedly disposed on the lower end of the panel 101.

[0038] The top of the chassis 1 is detachably equipped with a hanging plate 6, which is a cross-shaped hanging plate 6 and is detachably connected to the annular mounting plate 102. The lower end of the chassis 1 is connected to a frame 2 by screw threads; LED light sources 4 and power supplies 5 are provided on the inner top wall of the chassis 1, and the power supply 5 is electrically connected to the LED light sources 4. There are multiple LED light sources 4, which are arranged in a ring and uniformly to form an overall light-emitting array.

[0039] An LED light source 4 is provided on the inner top wall of panel 101. Panel 101, annular baffle 103, and diffuser 3 enclose a light source mounting cavity 7. The LED light source 4 is located inside the light source mounting cavity 7.

[0040] The top of the frame 2 is bent inward to form a second convex edge 202, and the bottom of the frame 2 is bent inward to form a first convex edge 201. A diffuser plate 3 is attached to the upper end of the first convex edge 201; the bottom end of the annular baffle 103 abuts against the top end of the diffuser plate 3. The top of the frame 2 is bent inward to form the second convex edge 202, and the panel 101 and the second convex edge 202 are threaded together. The frame 2 is located outside the annular baffle 103.

[0041] The upper surface of the diffuser plate 3 has five micro-hole zones 13 arranged radially from the inside to the outside: central light-transmitting zone 8, inner gradient zone 9, anti-glare zone 10, outer gradient zone 11, and edge light-transmitting zone 12. Each of the five micro-hole zones 13 has a micro-hole 13.

[0042] The vertical height between the anti-glare zone 10 and the LED light source 4 is set as H, the width of the light-emitting surface of the LED light source 4 is set as L, and the width of the anti-glare zone 10 is W=L+1.25×H; the center line of the anti-glare zone 10 and the center axis of the multiple LED light sources 4 are on the same vertical line.

[0043] The central light-transmitting area has 8 micro-holes 13 with an opening diameter of 0.1 mm, a depth of 0.02 mm, and a center-to-center distance of 0.8 mm between adjacent micro-holes 13.

[0044] The inner gradient zone 9 has a micropore 13 with an opening diameter of 0.4 mm and a depth of 0.08 mm. The distance between the centers of adjacent micropores 13 gradually decreases from the center outwards.

[0045] The anti-glare zone 10 has a micro-hole 13 with an opening diameter of 0.8 mm and a depth of 0.15 mm. The ratio of the center distance between adjacent micro-holes 13 to the opening diameter of the micro-hole 13 is 1:1.1.

[0046] The outer gradient zone 11 has a micropore opening diameter of 0.4 mm and a micropore depth of 0.08 mm. The distance between the centers of adjacent micropores 13 gradually increases from the center outwards.

[0047] The opening diameter of the micropore 13 in the edge light-transmitting area 12 is 0.1 mm, the depth of the micropore 13 is 0.02 mm, and the distance between the centers of adjacent micropores 13 is 0.8 mm.

[0048] The area ratio of the inner gradient zone 9, the anti-glare zone 10, and the outer gradient zone 11 is 0.5:1.5:1.

[0049] The axial cross-section of the micropore 13 is V-shaped; the central light-transmitting area 8, the inner gradient area 9, the anti-glare area 10, the outer gradient area 11, and the edge light-transmitting area 12 are all distributed in a square ring shape, and the corner positions are transitioned with rounded arcs.

[0050] Microhole 13 is processed by an ultraviolet laser drilling machine; the rated power of the ultraviolet laser drilling machine is 5W, and the center wavelength of the laser is 355nm.

[0051] When processing the anti-glare zone 10, the laser output power is 75% of the rated power, the processing speed is 1350mm / s, and the pulse frequency is 35kHz.

[0052] When processing the inner gradient region 9 and the outer gradient region 11, the laser output power is 50% of the rated power, the processing speed is 2750mm / s, and the pulse frequency is 55kHz.

[0053] When processing the edge light-transmitting area 12 and the central light-transmitting area 8, the laser output power is 20% of the rated power, the processing speed is 4500mm / s, and the pulse frequency is 80kHz.

[0054] When the opening diameter of the micropore 13 in the central light-transmitting area 8 or the edge light-transmitting area 12 is 0mm, that is, the central light-transmitting area 8 or the edge light-transmitting area 12 does not have a micropore 13.

[0055] The anti-glare zone 10 is densely covered with micropores 13 and inverted V-shaped micropores 13, which can intercept and refract direct strong light from the LED, improve the graininess of the light source, and eliminate glare. Excess light is diffusely reflected inside the lamp cavity, which can serve as a supplementary light source to provide secondary lighting for areas without light.

[0056] In the transition area between the inner and outer sides of panel 101, the density of micropores 13 gradually decreases, forming a soft optical transition zone. The brightness of the light changes smoothly accordingly, eliminating the harsh boundary between bright and dark areas and making the overall light emission effect consistent and uniform.

[0057] The central light-transmitting area of ​​panel 101 features a design with few or no holes, resulting in excellent light transmission. The reflected supplementary light can penetrate directly, effectively brightening the blank area in the center of the square LED array and achieving uniform overall brightness.

[0058] The edge light-transmitting area 12 also has a structure with few or no holes. Combining the advantages of the inner square and outer circle shape, it maximizes the release of lateral diffuse light, fills the lighting dead corners formed by the square light source at the corners of the circular panel 101, and effectively solves the problem of dark edges.

[0059] The suspended ceiling light provided by this invention adopts a standard component combination structure that does not require mold opening, eliminating the need for injection / die-casting molds, thus saving costs and shortening the cycle.

[0060] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
