Description

Technical Field

[0001] This invention relates to the field of lighting device technology, specifically an anti-glare mirror light based on a modular quick-release structure, which is particularly suitable for mirror lighting in bathrooms, dressing tables, and other similar settings. Background Technology

[0002] As a functional lighting fixture, vanity lights must meet three core requirements: 1. Optical performance requirements: uniform illuminance (>80%, according to GB / T 5700-2008), low glare value (UGR<19, CIE 117-1995 standard) to avoid visual fatigue in front of the eyes; 2. Installation and maintenance requirements: adaptable to various wall surfaces such as ceramic tiles and glass, easy to install, and easy to replace the driver power supply; 3. Structural reliability requirements: maintain IP54 level or higher protection in humid environments (IEC 60529), and the heat dissipation structure must ensure a lifespan of 50,000 hours (LM-80 test standard).

[0003] Currently, mainstream mirror light technology has the following typical defects: 1. Optical system defects: Chinese patent with publication number CN211106197Y discloses a mirror light transmittance structure, which adopts a single-layer planar diffuser, and the light is refracted only once, resulting in an illuminance attenuation of >40% at the edge of the mirror light spot (compared to the central area), and the measured UGR value is as high as 22.3; Japanese patent with publication number JP2019-156492A discloses a lighting device for a makeup mirror, which uses a frosted glass cover to reduce glare, but the light efficiency loss reaches 30% (the measured luminous flux is only 1,050LM when the input power is 15W). 2. Structural Design Defects: Chinese Patent CN210891476U discloses a vanity light mounting structure that uses screws to fix the light-transmitting cover (requiring the removal of 8 M3 screws). Replacing the driver power supply requires removing all screws. Chinese Patent CN209782524U discloses a vanity light mounting plate assembly. The integrated mounting plate only has Φ8mm round holes, which cannot be used with US standard Φ10mm hooks. Market sampling shows an installation compatibility rate of <65%. 3. Heat Dissipation and Maintenance Defects: Chinese Patent CN212901789Y discloses a vanity light driver heat dissipation structure that seals the driver power supply inside the lamp body. Under full load (20W), the temperature rise reaches 42℃ (ambient temperature 25℃), accelerating the aging of electrolytic capacitors. The measured lifespan is only 28,000 hours.

[0004] Based on the above analysis, existing vanity light technology has three major bottleneck problems:

[0005] 1. Imbalance in optical performance – The single-layer lens cover structure cannot simultaneously achieve low glare (UGR<16) and high luminous efficacy (>100LM / W), resulting in poor visual comfort in front of the lens;

[0006] 2. Low modularity – The light-transmitting cover and power supply are fixed with screws, resulting in low maintenance efficiency and low feasibility for users to replace them themselves;

[0007] 3. Insufficient installation compatibility – The mounting hole specifications are limited and cannot cover diverse international installation standards (GB / EN / UL), which restricts the global sales of the product. Summary of the Invention

[0008] To address the shortcomings of the existing technology, the present invention aims to provide an anti-glare headlight based on a modular quick-release structure. Through the innovative design of a double-layer light-transmitting cover and a quick-release mechanical structure, it achieves the following:

[0009] Glare rating UGR ≤ 13 and luminous efficacy > 100 LM / W;

[0010] The time required to replace the driver power supply is less than 30 seconds.

[0011] Compatible with mainstream global installation hooks (compatibility rate > 98%).

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] An anti-glare front light based on a modular block structure includes a mounting plate, a base, a semi-cylindrical lamp holder, a first light-transmitting cover, a second light-transmitting cover, a driver power supply box, a lamp cover, and an LED light panel.

[0019] Furthermore, the first slide structure includes a dovetail guide rail disposed on the side of the lamp holder and a dovetail guide rail groove disposed on the edge of the second light-transmitting cover.

[0020] Furthermore, the V-shaped opening of the first light-transmitting cover has an inclination angle of 120°±5°, and the two arms of the V-shaped opening are connected by a smooth arc transition structure. The inner surface of the first light-transmitting cover is provided with a nano-soft light coating.

[0021] Furthermore, the lamp holder is provided with a power supply box opening at the position corresponding to the position of the driver power supply box, through which the driver power supply box can be quickly disassembled and assembled.

[0024] Furthermore, the sidewall of the drive power supply box is provided with parallel heat dissipation fins, and the top is integrated with a wave-shaped heat-conducting copper pipe.

[0025] Furthermore, the lamp holder is made of 6063-T5 aluminum alloy.

[0026] Furthermore, the circular hanging holes include three specifications: Φ6mm, Φ8mm, and Φ10mm.

[0027] Furthermore, the width of the entrance end of the arc-shaped hanging hole is 20% greater than that of the locking end, and a silicone damping layer is provided on the inner wall of the locking end.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. Breakthrough in optical performance: The dual-stage optical path achieves a spot uniformity of >92% (measured according to GB / T 9473-2017); the optimized V-shaped cover tilt angle suppresses specular reflection glare, reducing the UGR value to 12.8;

[0030] 2. Improved maintenance efficiency: The quick-release structure of the drive power supply box reduces replacement time by 87% (traditional 480 seconds → this solution 38 seconds); the sliding connection structure design enables tool-free disassembly of the light-transmitting cover;

[0031] 3. Enhanced installation versatility: Multiple hanging hole specifications cover GB / EN / UL standards, with a compatibility rate of 98.6%; the arc-shaped hanging hole anti-detachment flange + silicone damping layer provides a pull-out resistance of up to 150N (tested according to GB / T 2423.55).

[0042] Please see Figures 1-6 This invention provides an anti-glare headlight based on a modular quick-release structure, the main innovations of which are as follows:

[0043] 1. Overall structural layout

[0044] This vanity light adopts a layered modular structure, including: a mounting plate 1, a base 2, a lamp holder 3, a first light-transmitting cover 4, a second light-transmitting cover 5, a driver power supply box 6, two lamp covers 7, and an LED light panel 8. The lamp holder 3 is a semi-cylindrical structure, which can be die-cast from 6063-T5 aluminum alloy to improve heat dissipation. Its outer diameter radius is 50mm, and its length can be customized to 300mm or 450mm according to power requirements. Dovetail guide rails 311 are machined on both sides of its edges to guide the assembly of the second light-transmitting cover 5. The second light-transmitting cover 5 can be injection molded from high-transmittance PMMA material, with a thickness of 1.5mm, and has a semi-cylindrical curved surface. Its edges are integrally formed with dovetail guide rail grooves 312, which can slide and engage with the dovetail guide rails 311 of the lamp holder 3. The two components, when combined, form a complete cylindrical enclosed space, creating an internal accommodating space 9 with a radius of 50mm. The first light-transmitting cover 4 covers the outer side of the cylindrical structure. It is made of UV-resistant PC material and formed into a V-shaped opening structure through vacuum forming. The tilt angle of the V-shaped opening is precisely controlled at 120°±1°. The two arms are connected by a smooth arc transition structure 41 with a radius of R60mm to avoid light spot interruption. The inner surface of the first light-transmitting cover 4 has a 2μm thick nano-silica soft light coating with a refractive index of 1.46 formed by vapor deposition. Two lamp covers 7 are respectively arranged at both ends of the cylindrical structure. They are made of flame-retardant ABS engineering plastic injection molding. The lamp holder 3 has a bolt groove 32 formed in it. The lamp covers 7 are fixed to the bolt groove 32 of the lamp holder 3 by bolts.

[0045] In low-cost application scenarios, the lamp holder 3 can also be replaced with glass fiber reinforced nylon material, and the second light-transmitting cover 5 can be made of tempered glass. In this case, a silicone sealing strip can be added in the dovetail guide rail groove 312 to achieve buffer sealing.

[0046] 2. Optical System Construction

[0047] The inner surface of the second light-transmitting cover 5 is formed by a precision molding process, creating a microprism array with a prism angle of 109°±1° and a distribution density of 1250 prisms / cm². This array causes wide-angle scattering of the direct light emitted by the LED light source, with a scattering angle of up to 140°. The V-shaped structure of the first light-transmitting cover 4 has a tilt angle of 120°, and its inner surface is coated with a nano-soft light coating containing silica particles with a particle size of 50nm, which modulates the scattered light secondaryly through the principle of diffuse reflection. An air gap of 10-20mm is maintained between the two light-transmitting covers, forming a dual-stage light path refraction channel. The radius of curvature of the arc-shaped transition structure 41 is set according to the air gap between the two light-transmitting covers, so that the arc-shaped transition structure 41 and the second light-transmitting cover 5 form a parallel gap, which can eliminate the light concentration phenomenon at the sharp corner of the traditional V-shaped cover.

[0048] In an alternative implementation, the microprism array can be replaced with a diffusion texture formed by laser etching, with a surface roughness of Ra 1.8 μm; the soft-light coating can be made of zirconium oxide, with a refractive index increased to 1.52 but adhesion reduced to 3B level.

[0049] 3. Quick-release mechanical structure

[0050] The dovetail guide rails 311 on both sides of the lamp holder 3 are designed with guide slopes. When they mate with the dovetail guide rail grooves 312 on the edge of the second light-transmitting cover 5, quick installation can be achieved simply by sliding the second light-transmitting cover 5 into the lamp holder 3 from one end. The LED light board 8 is mounted on the lamp holder 3 via the light board mounting base 81. The LED light board 8 can be bonded to the surface of the light board mounting base 81 with thermally conductive silicone, and its wiring channel is hidden inside the slot. The light board mounting base 81 can be stamped from 1050 aluminum alloy to enhance heat dissipation. The light board mounting base 81 has mounting flanges 811 extending along the length direction on both sides. The lamp holder 3 has corresponding through mounting slots 34, and the light board mounting base 81 can be inserted into the mounting slots 34 from one end of the lamp holder 3. The driver power supply box 6 is detachably mounted on the back of the lamp board mounting base 81 via a snap-fit ​​structure. The sidewalls of the driver power supply box 6 are machined with parallel heat dissipation fins spaced 2mm apart and 8mm high. A 0.5mm thick corrugated copper heat pipe is embedded in the top, filled with paraffin / graphene composite phase change material. To facilitate quick assembly and disassembly of the driver power supply box 6, an opening 33 is provided on the lamp holder 3 corresponding to the position of the driver power supply box 6, allowing for rapid assembly and disassembly. The controller 10 of the LED lamp board 8 can be fixed to the back of the lamp board mounting base 81 using M2.5 stainless steel bolts. In other embodiments, the sliding groove connection structure between the lamp board mounting base 81 and the lamp holder 3 can be replaced with a magnetic guide rail, using a samarium cobalt magnetic strip with a magnetic flux density of 0.8T.

[0051] A threaded mounting hole is provided inside the lamp cover 7. A locking bolt 71 secures the first light-transmitting cover 4 to the lamp cover 7. To precisely control the gap between the first light-transmitting cover 4 and the second light-transmitting cover 5, a positioning element 72 is arranged between them. The locking bolt 71 passes through the positioning element 72 and is then screwed into the threaded mounting hole of the lamp cover 7. The gap between the first light-transmitting cover 4 and the second light-transmitting cover 5 is controlled by the length of the positioning element 11. An outer cover 73 is also provided on the outside of the lamp cover 7 to conceal the internal connection structure and improve aesthetics.

[0052] 4. Installation Mechanism Details

[0053] Mounting plate 1 is made of 1.2mm thick 304 stainless steel sheet, stamped and formed, with a sandblasted anti-glare surface. It features three types of mounting holes: circular mounting holes 12 include three specifications strictly designed according to international standards: Φ6mm (Chinese GB standard), Φ8mm (European EN standard), and Φ10mm (American UL standard), with the center-to-center spacing controlled at 50.0mm ± 0.05mm; arc-shaped mounting holes 13 are designed as arc channels with a central angle of 30°, a depth of 6.0mm, an entrance width of 6.0mm, a locking end width of 5.0mm, and an edge with a 1.5mm high anti-detachment flange. A 0.3mm thick silicone damping layer with a damping coefficient of 0.6 can be adhered to the inner wall of the locking end, providing a pull-out resistance of 180N. The base 2 can be fixed to the back of the lamp holder 3 using four sets of M4 stainless steel bolts, while the mounting plate 1 is laser-welded to the base 2 to form a single unit.

[0054] In other embodiments, the anti-detachment flange can be designed as a spring steel sheet structure; the silicone damping layer can be replaced with polyurethane material, with the thickness increased to 0.5 mm to improve damping performance.

[0055] The working principle of this invention is as follows: When the LED light panel 8 is powered on and emits light, the light first penetrates the second light-transmitting cover 5. The micro-prism array on its inner surface decomposes the direct light into multi-directional scattered light, with the scattering angle extending to 140°. These scattered light rays undergo natural light mixing when passing through the air layer, and then collide with the nano-soft light coating (42) on the inner wall of the first light-transmitting cover 4. The V-shaped tilt design causes the light to refract in a specific direction, and the smooth transition structure 41 eliminates abrupt changes in edge light spots, ultimately outputting a surface light source with UGR≤13 and uniformity>92%. In terms of mechanical operation, during installation, simply align the wall hook with the circular hanging hole 12 or the entrance of the arc-shaped hanging hole 13 on the mounting plate 1, press down on the lamp body to make the hook slide along a 30° arc trajectory to the locking end, and rotate 15° to cause the silicone damping layer to deform and lock. During maintenance, first remove the outer cover 9, then insert and remove the second light-transmitting cover 5 through the sliding groove structure to disengage it from the dovetail guide rail 311 to remove the optical components. The drive power box 6 can be vertically inserted and removed through the power box opening 33 for quick replacement.

[0056] The vanity light product of this invention is particularly suitable for three types of harsh environments:

[0057] 1. Home Bathroom: IP54 protection rating can withstand continuous water mist corrosion, V-shaped light-transmitting cover tilt design can effectively suppress mirror reflection glare, and silicone damping layer maintains stable damping performance in humid environments.

[0058] 2. Professional Makeup Room: The dual-level optical system provides high color rendering illumination with Ra>90, and the 98.6% mounting hole compatibility allows it to be adapted to the installation system of various luxury makeup mirrors.

[0059] 3. Hotel bathroom: The quick-release structure allows the power supply replacement time to be controlled within 30 seconds, and the phase change material inside the corrugated heat-conducting copper pipe can ensure the long-term stable operation of the drive power supply at an ambient temperature of 40℃.

[0060] In extreme environment testing, when the ambient humidity reaches 95%RH, the anti-corrosion coating of the magnetic ring results in a magnetic force attenuation rate of <3%; after 100,000 insertion and removal tests, the wear of the dovetail guide rail 311 is only 0.05mm (based on GB / T 10125-2021 salt spray test and GB / T 2423.55 mechanical durability test).
