Description

Technical Field

[0001] This utility model relates to the field of ceiling downlight technology, specifically an anti-glare ceiling downlight. Background Technology

[0002] Ceiling downlights, as commonly used lighting fixtures in indoor lighting, are widely used in residential, commercial, and office spaces. Their core requirement is to provide uniform and comfortable lighting effects, while also being suitable for concealment and decorative purposes when installed on ceilings. With increasing demands for lighting quality, glare control, heat dissipation, and lighting flexibility have become key issues restricting the further development of traditional ceiling downlights. Specific technical challenges are as follows:

[0003] Traditional ceiling downlights often employ a single reflector structure, where the reflected light from LED sources easily creates direct, intense glare or localized bright spots. On one hand, some fixtures, in pursuit of high brightness, fail to optimize the light propagation path, resulting in glare when the light shines directly into the eyes, causing eye strain, especially in spaces where people spend long periods, such as offices and bedrooms. On the other hand, existing anti-glare solutions often rely on a single method, which, while reducing glare to some extent, comes with reduced light utilization or limited illumination range, making it difficult to simultaneously meet the dual requirements of anti-glare and highly uniform lighting. Furthermore, most fixtures rely solely on natural heat dissipation from the outer casing, lacking dedicated heat dissipation channels for the LED light source, causing heat to accumulate inside the fixture and hindering rapid heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide an anti-glare ceiling downlight to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-glare ceiling downlight, comprising an outer shell and a metal panel, wherein heat dissipation fins are uniformly arranged on the surface of the outer shell, and a reflective sphere is installed on the inner side of the outer shell through a support ring, and a mirror coating and a diffuse reflection coating are provided on both sides of the reflective sphere, and an inner bowl is provided on the inner wall of the outer shell outside the reflective sphere, and a nano light guide plate is provided on the inner wall of the inner bowl;

[0006] A metal panel is provided at the opening of the outer shell. A hole is provided in the center of the metal panel. A light-transmitting lens is installed inside the hole. An annular groove is provided on the inner wall of the metal panel outside the hole. An LED light ring is installed inside the annular groove through thermally conductive double-sided adhesive.

[0007] Preferably, a slot is provided at the center of the top of the outer shell, and an adjusting wheel is installed on the inner side of the slot via a rotating shaft, and the outer wall of the adjusting wheel abuts against the side wall of the reflective sphere.

[0008] Preferably, both sides of the outer shell are bolted with memory metal clips, and the top of each of the two memory metal clips is provided with a fixing card.

[0009] Preferably, the outer shell has a fixing frame for mounting the support ring inside, the fixing frame has evenly arranged mating grooves with threaded holes, and the outer side of the support ring has evenly arranged mating bait blocks that match the mating grooves, and the center of the mating bait block has a fixing hole.

[0010] Preferably, a convex ring platform for supporting the light-transmitting lens is provided on the inner side of the hole, and a sealing ring is provided on the outer side of the light-transmitting lens.

[0011] Preferably, the inner surface of the light-transmitting lens facing the reflective sphere is provided with a nanoscale microstructure array, which is composed of hemispherical pits and uniformly covers the inner surface of the light-transmitting lens.

[0012] This utility model provides an anti-glare ceiling downlight, which has significant advantages over existing technologies, as detailed below:

[0013] 1. This invention, by setting a mirror coating and a diffuse reflection coating on both sides of the reflective sphere, allows for flexible adjustment of the light reflection mode according to actual needs. The adjustment wheel design allows the reflective sphere to rotate freely, and users can adjust the orientation of the mirror coating or the diffuse reflection coating as needed, thereby achieving precise control of light. The nanoscale microstructure array on the inner surface of the light-transmitting lens consists of hemispherical pits. This microstructure can diffuse light a second time, effectively weakening the intensity of direct light and further reducing glare. Through this multi-layered light processing mechanism, this invention can significantly improve the anti-glare effect and provide a more comfortable light environment.

[0014] 2. The evenly distributed heat dissipation fins on the outer casing increase the heat dissipation area and improve heat dissipation efficiency. Simultaneously, the metal panel is connected to the LED light ring via thermally conductive double-sided adhesive, forming a structure for simultaneous heat dissipation from top to bottom. This not only ensures the heat dissipation requirements of the LED light ring but also extends the lifespan of the lamp and reduces performance degradation caused by high temperatures.

[0015] 3. The reflector sphere is connected to the outer casing via an adjusting wheel. The outer wall of the adjusting wheel abuts against the side wall of the reflector sphere. Users can easily adjust the position of the reflector sphere by rotating the adjusting wheel, thereby changing the angle of light reflection. This not only makes operation simple but also meets the lighting needs of different scenarios, improving the applicability and flexibility of the lamp.

[0016] 4. The nano-light guide plate installed on the inner wall of the bowl effectively refracts the light emitted by the LED ring, distributing it evenly across the coating of the reflective sphere. This not only improves light utilization but also ensures light uniformity, enhancing the overall lighting effect. Attached Figure Description

[0030] The surface of the outer shell 1 is uniformly provided with heat dissipation fins 3. The heat dissipation fins 3 are elongated and extend outward along the radial direction of the outer shell 1 to form multiple parallel fin structures, which can effectively increase the heat dissipation area and improve the heat dissipation efficiency.

[0031] A reflective sphere 8 is mounted on the inner side of the outer casing 1 via a support ring 13. The support ring 13 is fixed to the inner wall of the outer casing 1 by bolts to ensure its stability.

[0032] A slot 25 is provided at the center of the top of the outer casing 1. An adjusting wheel 16 is mounted on the inner side of the slot 25 via a rotating shaft 15. The two ends of the rotating shaft 15 are fixed to the two side walls of the slot 25 respectively, using a bearing structure to ensure that the adjusting wheel 16 can rotate flexibly. The outer wall of the adjusting wheel 16 abuts against the side wall of the reflector 8. When it is necessary to adjust the position of the reflector 8, the user can manually rotate the adjusting wheel 16. The outer wall of the adjusting wheel 16 contacts the side wall of the reflector 8, and the reflector 8 is rotated by friction.

[0033] The outer casing 1 has a fixing frame 2 for mounting the support ring 13. The fixing frame 2 is evenly provided with mating grooves 4 with threaded holes, and the outer side of the support ring 13 is evenly provided with mating bait blocks 12 that match the mating grooves 4. The center of the mating bait block 12 is provided with a fixing hole 14.

[0034] The fixing frame 2 is located inside the outer shell 1 and is mainly used for the installation of the support ring 13. The fixing frame 2 is also made of high-strength material to ensure the stability of the overall structure. The shape of the fixing frame 2 is designed according to the inner cavity shape of the outer shell 1 to ensure that it can be firmly fixed inside the outer shell 1.

[0035] Several mating grooves 4 are evenly arranged on the fixed frame 2, and each mating groove 4 has a threaded hole. The design of the mating grooves 4 allows the support ring 13 to be tightly connected to it through the mating bait block 12. The design of the threaded hole makes it easy to fix the mating bait block 12 in the mating groove 4 with fasteners such as bolts, thereby ensuring the stability of the support ring 13.

[0036] The support ring 13 is located above the fixed frame 2, and docking bait blocks 12 that match the docking groove 4 are evenly arranged on its outer side. The support ring 13 is made of a material with good elasticity and wear resistance to ensure that it is not easily deformed or worn during use.

[0037] The docking bait block 12 has a fixing hole 14 at its center. The fixing hole 14 allows the docking bait block 12 to be aligned with the threaded hole in the docking groove 4 and fixed with fasteners such as bolts. The shape and size design of the docking bait block 12 enable it to fit tightly with the docking groove 4, ensuring the stability of the support ring 13.

[0038] The fixing hole 14 is located at the center of the mating block 12, and its diameter matches the diameter of fasteners such as bolts. The design of the fixing hole 14 allows the fasteners to pass through smoothly and be tightened into the threaded holes in the mating groove 4, thereby achieving a firm connection between the support ring 13 and the fixing frame 2.

[0039] The reflective sphere 8 has a mirror coating 17 and a diffuse reflection coating 20 on both sides. The outer shell 1 of the reflective sphere 8 has an inner bowl 7 on its inner wall, and the inner wall of the inner bowl 7 has a nano light guide plate 18.

[0040] Reflective sphere 8: The reflective sphere 8 is made of high-purity optical-grade materials to ensure the light reflection efficiency. It is coated with a mirror coating 17 and a diffuse reflection coating 20 on both sides. The mirror coating 17 is made of high-reflectivity materials, such as aluminum or silver, and is uniformly coated by vacuum coating technology to ensure efficient light reflection. The diffuse reflection coating 20 is made of materials with scattering properties, such as silicon dioxide or zinc oxide, and is uniformly coated by spraying process to make light scatter uniformly.

[0041] Inner bowl 7: The inner bowl 7 is fixed to the inner wall of the outer shell 1 and is made of the same material as the outer shell 1 to ensure the stability of the overall structure. Its inner wall is designed to be concave to better accommodate and guide light.

[0042] Nano light guide plate 18: The nano light guide plate 18 is set on the inner wall of the inner bowl 7 and is made of nano-level light guide material, which has excellent light guiding and uniform distribution characteristics.

[0043] A metal panel 10 is provided at the opening of the outer casing 1. A hole 19 is provided in the center of the metal panel 10. A light-transmitting lens 11 is installed inside the hole 19. An annular groove 22 is provided on the inner wall of the metal panel 10 outside the hole 19. An LED light ring 9 is installed inside the annular groove 22 through a thermally conductive double-sided adhesive 21.

[0044] Metal panel 10: The metal panel 10 is located at the opening of the housing 1 and is made of aluminum alloy or other metal materials with good thermal conductivity. A hole 19 is provided in the center of the metal panel 10. The diameter of the hole 19 is designed according to actual needs to ensure the installation of the light-transmitting lens 11 and the light transmission effect.

[0045] Transparent lens 11: The transparent lens 11 is installed inside the hole 19 and is made of a high light transmittance material such as acrylic or glass. The edge of the transparent lens 11 is tightly fitted to the inner wall of the hole 19 to ensure that light can pass through evenly.

[0046] Annular groove 22: An annular groove 22 is provided on the inner wall of the metal panel 10 outside the hole 19. The depth and width of the annular groove 22 are designed according to the size of the LED light ring 9 to ensure the stable installation of the LED light ring 9.

[0047] Thermally conductive double-sided adhesive 21: Thermally conductive double-sided adhesive 21 is installed inside the annular groove 22 to fix the LED ring 9. Thermally conductive double-sided adhesive 21 not only has an adhesive function, but also effectively conducts the heat generated by the LED ring 9, improving heat dissipation efficiency.

[0048] LED Light Ring 9: The LED light ring 9 is mounted in the annular groove 22 using thermally conductive double-sided adhesive 21, and multiple LED beads are evenly distributed on the light ring. The power cord of the LED light ring 9 is led out through the wiring groove inside the housing 1 and connected to an external power source.

[0049] The inner side of the hole 19 is provided with a convex ring platform 24 for supporting the light-transmitting lens 11, and the outer side of the light-transmitting lens 11 is provided with a sealing ring 23.

[0050] The inner surface of the light-transmitting lens 11 facing the reflective sphere 8 is provided with a nanoscale microstructure array 26, which is composed of hemispherical pits and uniformly covers the inner surface of the light-transmitting lens 11.

[0051] The nanoscale microstructure array 26 is composed of hemispherical pits. The nanoscale microstructure array 26 uniformly covers the inner surface of the light-transmitting lens 11, ensuring that the reflection loss can be effectively reduced and the utilization rate of light can be improved during the reflection and transmission process between the light-transmitting lens 11 and the reflective sphere 8.

[0052] A convex annular platform 24 for supporting the light-transmitting lens 11 is provided on the inner side of the hole 19. The height of the convex annular platform 24 is 0.5 mm to 1.5 mm, and the width is 1 mm to 3 mm. The material is the same as or similar to that of the light-transmitting lens 11 to ensure the consistency of the coefficient of thermal expansion and prevent stress concentration caused by temperature changes. The outer diameter of the convex annular platform 24 is slightly smaller than the inner diameter of the hole 19 to facilitate the installation and fixation of the light-transmitting lens 11.

[0053] A sealing ring 23 is provided on the outer side of the light-transmitting lens 11. The sealing ring 23 is made of an elastic material, such as silicone rubber or fluororubber. The cross-section of the sealing ring 23 is circular or elliptical, and its diameter is slightly larger than the outer diameter of the light-transmitting lens 11 to ensure a sealing effect. The function of the sealing ring 23 is to prevent external dust and moisture from entering the space between the light-transmitting lens 11 and the reflective sphere 8, ensuring the long-term stable operation of the device.

[0054] In this embodiment, the coating orientation of the reflective sphere 8 is adjusted according to actual lighting needs. A hand is inserted into the slot 25 at the top of the outer casing 1, and the adjusting wheel 16, mounted on the inner side of the slot 25 via the rotating shaft 15, is rotated. Since the outer wall of the adjusting wheel 16 contacts the side wall of the reflective sphere 8, the rotating wheel 16 causes the reflective sphere 8 to rotate due to friction. When strong direct lighting is needed, the side of the reflective sphere 8 with the mirror coating 17 is turned towards the direction of light incidence from the LED ring 9. The mirror coating 17 efficiently reflects the light, which is then emitted through the light-transmitting lens 11. When soft, diffused lighting is needed to avoid glare, the side of the reflective sphere 8 with the diffuse reflection coating 20 is turned towards the direction of light incidence. The diffuse reflection coating 20 evenly scatters the light, which is then diffused a second time by the nanoscale microstructure array 26 on the inner surface of the light-transmitting lens 11 before being emitted, further reducing glare.

[0055] The power cord of the LED ring 9 is led out from the wiring groove inside the outer shell 1 and connected to the external mains power line in accordance with electrical specifications. After the connection is completed, the power switch is turned on, the LED ring 9 is powered on and emits light. The light initially shines on the nano light guide plate 18 on the inner wall of the inner bowl 7. After being uniformly distributed by the nano light guide plate 18, the light is conducted to the surface of the reflective sphere 8.

[0056] Holding the outer casing 1, gently press the two memory metal clips 6 inwards, then align the outer casing 1 with the mounting hole on the ceiling and push it in; once the outer casing 1 is fully embedded in the mounting hole, release the memory metal clips 6, which will return to their original shape under the effect of memory performance, and the fixing clip 5 at the top will lock into the edge of the ceiling opening, thus fixing the outer casing 1 in the ceiling. Finally, gently pull the outer casing 1 to confirm that it is firmly fixed and to prevent it from loosening.

[0057] In daily use, the heat dissipation fins 3 on the surface of the outer casing 1 will naturally dissipate the heat transferred by the LED ring 9, and the metal panel 10 will also conduct the heat of the LED ring 9 through the thermally conductive double-sided adhesive 21.
