Description

Technical Field

[0001] This utility model relates to the field of downlight technology, specifically an anti-glare downlight with a movable light-emitting surface. Background Technology

[0002] In modern architectural lighting, downlights, as recessed lighting fixtures, are widely used in various scenarios such as homes, offices, and commercial spaces due to their convenient installation and simple appearance. Traditional downlights typically consist of a lamp body, reflector, LED light source, and lens, and their core function is to illuminate a specific area through a fixed beam angle.

[0003] However, existing downlights have many limitations in practical applications, mainly in the following aspects: The luminous surface angle (such as beam angle) of traditional downlights is directly determined by the structure of the reflector and lens. After production, the angle is fixed and cannot be adjusted, and the beam projection direction forms a fixed straight-line angle with the lamp body. This design cannot adjust the beam direction according to the installation environment when facing special ceiling structures (such as recessed ceilings, concealed ceilings, and irregularly shaped ceilings with a higher front and lower back), easily leading to blind spots, uneven light distribution, or projection position deviations, making it difficult to meet personalized lighting needs. Furthermore, due to the fixed angle, the same traditional downlight is difficult to adapt to various installation scenarios. For example, when oblique supplemental lighting is needed in irregularly shaped ceilings, additional lamps with specific angles must be purchased; in recessed or concealed installations, compatible models must be changed. This not only increases the user's procurement costs and inventory pressure but also reduces the versatility and installation efficiency of the lamps. Utility Model Content

[0004] The purpose of this invention is to provide an anti-glare downlight with a movable light-emitting surface 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 downlight with a movable light-emitting surface, comprising a front housing, a middle connecting frame, and a rear housing. The front housing and the rear housing are respectively provided with an inner ring of the front housing and an inner ring of the rear housing. A rotating ring is provided on the outer edge of the inner ring of the front housing. A support ring matching the rotating ring is provided inside the front housing. The front housing and the rear housing are connected by the middle connecting frame, and the two ends of the middle connecting frame extend into the interior of the front housing and the rear housing and are respectively connected to the inner ring of the front housing and the inner ring of the rear housing.

[0006] Bait blocks are symmetrically arranged at both ends of the support bowl on one side of the inner ring of the rear housing. Fixing holes are provided on the side wall of the middle connecting frame at the positions of the two bait blocks. The fixing holes are provided with a rotating shaft for connecting the bait blocks and the middle connecting frame. Limiting shafts are provided on the inner ring of the rear housing on one side of the two bait blocks through the docking holes. An angle limiting hole is provided on the support edge on one side of the inner ring of the rear housing at the position of the limiting shaft.

[0007] Preferably, a nano-electroplated anti-glare reflective bowl is installed inside the support bowl via a bowl sleeve, and an LED light panel is provided on the inner side of the nano-electroplated anti-glare reflective bowl.

[0008] Preferably, one side of the support edge is provided with a notch for angle adjustment.

[0009] Preferably, the angle limiting hole is composed of multiple holes connected in series, the inner diameter of each hole is larger than the outer diameter of the limiting shaft, and the opening between each hole is slightly smaller than the diameter of the limiting shaft.

[0010] Preferably, anti-slip limiting plates are provided on both sides of the front housing of the lamp body, and the top of each anti-slip limiting plate is provided with a connecting piece through a memory elastic sheet, and the connecting piece is connected and fixed to the connecting hole provided on the side wall of the front housing of the lamp body by screws.

[0011] Preferably, a support panel is provided at the opening of the front housing of the lamp body, and the diameter of the support panel is larger than the diameter of the front housing of the lamp body.

[0012] Preferably, a lens is provided at the front end of the inner ring of the front housing, and snap-fit ​​blocks are evenly provided on the side of the inner ring of the front housing facing the intermediate connecting frame, and snap-fit ​​holes are provided on the side wall of the intermediate connecting frame at the positions corresponding to the snap-fit ​​blocks.

[0013] Preferably, the back of the rear housing is provided with heat dissipation holes in the shape of a trademark pattern.

[0014] This invention provides an anti-glare downlight with a movable light-emitting surface, which has the following significant advantages compared to the prior art:

[0015] 1. By setting a rotating ring on the outer edge of the inner ring of the front housing, and matching it with the support ring inside the front housing of the lamp body, the inner ring of the front housing can rotate 0-360° inside the front housing of the lamp body. This greatly improves the adjustment flexibility of the light-emitting surface, allowing users to freely adjust the light-emitting direction according to actual needs, thereby achieving a multi-angle, blind-spot-free projection effect.

[0016] The symmetrically arranged blocks at both ends of the support bowl on one side of the inner ring of the rear housing, along with the corresponding fixing holes and rotating shaft design on the side wall of the intermediate connecting frame, allow the angle between the rear housing and the intermediate connecting frame to be adjusted from 0-30°. Combined with the limiting function of the limiting shaft and angle limiting holes, the position of the light-emitting surface can be flexibly adjusted according to different ceiling structures, ensuring that light can be accurately projected onto the desired area, avoiding the blind spots caused by the fixed angle of traditional downlights.

[0017] 2. Because this utility model has a flexible light-emitting surface adjustment function, the same lamp can be used for various lighting scenarios, such as the needs of different environments like living rooms, bedrooms, and offices. This multi-purpose design not only simplifies the user's purchasing process but also reduces the purchase and maintenance costs of lamps and improves usage efficiency.

[0018] With multi-angle adjustment, this utility model can meet the lighting needs of different heights. Whether it is a low ceiling or a high space, it can achieve the ideal lighting effect and greatly expand the application range of the lamp.

[0019] 3. The nano-electroplated anti-glare reflector used in this utility model can effectively improve light reflection efficiency and reduce light energy loss, thereby achieving energy-saving effects. At the same time, the nano-electroplating layer also has an anti-glare function, reducing glare stimulation to the eyes and providing a more comfortable lighting environment.

[0020] The logo-shaped ventilation holes on the back of the housing not only enhance brand recognition but also effectively improve heat dissipation efficiency and extend the lifespan of the lamp.

[0021] This invention enables 0-30° tilt adjustment and 0-360° rotation adjustment of the luminous surface. It can precisely adjust the beam projection direction according to special structures such as recessed ceilings, hidden ceilings, and irregularly shaped ceilings with a high front and low back, so as to meet the personalized lighting needs of users in different scenarios and improve the overall user experience.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-5 The present invention provides an embodiment of an anti-glare downlight with a movable light-emitting surface, comprising a front housing 1, a middle connecting frame 2, and a rear housing 5. Anti-slip limiting plates 3 are provided on both sides of the front housing 1. The top of each of the two anti-slip limiting plates 3 is provided with a connecting piece 13 through a memory elastic sheet 12, and the connecting piece 13 is connected and fixed to the connecting hole 10 provided on the side wall of the front housing 1 by screws 11.

[0031] A support panel 9 is provided at the opening of the front housing 1 of the lamp body, and the diameter of the support panel 9 is larger than the diameter of the front housing 1 of the lamp body.

[0032] The front housing 1 of the lamp body is made of high-strength plastic or metal and is cylindrical in shape with a circular opening for mounting the support panel 9. Multiple connection holes 10 are provided on the side wall of the front housing 1 for fixing the connecting piece 13 with screws 11.

[0033] Anti-slip limiting plates 3 are installed on both sides of the front housing 1 of the lamp body and are made of anti-slip material to ensure that the lamp body will not slide during use. The top of the anti-slip limiting plate 3 is connected to the connecting piece 13 through a memory elastic sheet 12. The memory elastic sheet 12 has good elasticity and memory function and can return to its original position after the connecting piece 13 moves.

[0034] The connecting piece 13 is connected and fixed to the connecting hole 10 on the side wall of the front housing 1 of the lamp body by screws 11, ensuring that the anti-slip limiting plate 3 is firmly fixed on the front housing 1 of the lamp body. The connecting piece 13 is made of high-strength metal and has good corrosion resistance and mechanical strength.

[0035] The support panel 9 is located at the opening of the front housing 1 of the lamp body, and its diameter is larger than that of the front housing 1 of the lamp body, so as to ensure that the light-emitting surface can be fully supported and protected.

[0036] When installation is required, press the anti-slip limiting plate 3. Under the action of the memory elastic sheet 12, the distance between the two anti-slip limiting plates 3 decreases, making it easier to insert into the installation hole. Release the anti-slip limiting plate 3. Due to the action of the memory elastic sheet 12, the anti-slip limiting plate 3 can automatically return to its original position after being moved, fixing the position of the downlight in the installation hole and ensuring the stability and safety of the lamp body.

[0037] The front housing 1 and the rear housing 5 of the lamp body are respectively provided with inner rings 21 of the front housing 1 and the rear housing 5, and the back of the rear housing 5 is provided with heat dissipation holes 6 in the shape of trademark pattern.

[0038] The main functions of the front housing inner ring 15 and the rear housing inner ring 21 are to enhance the structural strength of the housing and provide a mounting base for other components.

[0039] The back of the rear housing 5 features ventilation holes 6 shaped like the trademark pattern. These ventilation holes 6 not only serve a heat dissipation function but also act as decorative elements, increasing product recognizability. The design of the ventilation holes 6 should ensure airflow to improve heat dissipation efficiency.

[0040] A rotating ring 28 is provided on the outer edge of the inner ring 15 of the front housing. A support ring 29 matching the rotating ring 28 is provided inside the front housing 1 of the lamp body. The front housing 1 and the rear housing 5 of the lamp body are connected by an intermediate connecting frame 2. The two ends of the intermediate connecting frame 2 extend into the interior of the front housing 1 and the rear housing 5 of the lamp body, respectively, and are connected to the inner ring 15 of the front housing and the inner ring 21 of the rear housing, respectively.

[0041] A lens 8 is provided at the front end of the inner ring 15 of the front housing. The inner ring 15 of the front housing is provided with snap-fit ​​blocks 14 evenly on the side facing the intermediate connecting frame 2, and snap-fit ​​holes 16 are provided on the side wall of the intermediate connecting frame 2 at the positions corresponding to the snap-fit ​​blocks 14.

[0042] A rotating ring 28 is provided on the outer edge of the inner ring 15 of the front housing. The rotating ring 28 is designed to rotate around the inner ring 15 of the front housing, thereby realizing the adjustment function of the lamp. A support ring 29 matching the rotating ring 28 is provided inside the front housing 1 of the lamp body. The function of the support ring 29 is to fix the rotating ring 28 and ensure its stability and reliability during rotation.

[0043] The front housing 1 and the rear housing 5 of the lamp body are connected by an intermediate connecting bracket 2. Both ends of the intermediate connecting bracket 2 extend into the interior of the front housing 1 and the rear housing 5, respectively, and are connected to the inner ring 15 of the front housing and the inner ring 21 of the rear housing. This connection method not only improves the overall stability of the lamp but also facilitates the installation and disassembly of various components.

[0044] A lens 8 is provided at the front end of the inner ring 15 of the front housing. The function of the lens 8 is to focus and scatter light, thereby adjusting the distribution and intensity of the light. The lens 8 should be made of a material with good light transmission properties to ensure the efficiency of light transmission.

[0045] The inner ring 15 of the front housing is provided with snap-fit ​​blocks 14 evenly on the side facing the intermediate connecting frame 2. The side wall of the intermediate connecting frame 2 is provided with snap-fit ​​holes 16 at the positions of the snap-fit ​​blocks 14. The design of the snap-fit ​​blocks 14 and the snap-fit ​​holes 16 enables the inner ring 15 of the front housing and the intermediate connecting frame 2 to be firmly connected by snap-fit, ensuring the stability of the lamp structure.

[0046] The support bowl 26 on one side of the inner ring 21 of the rear shell is symmetrically equipped with bait blocks 20 at both ends. The support bowl 26 is equipped with a nano-electroplated anti-glare reflective bowl 23 through a bowl sleeve 22, and an LED light panel 27 is provided on the inner side of the nano-electroplated anti-glare reflective bowl 23.

[0047] The function of the sleeve 22 is to ensure that the nano-electroplated anti-glare reflective bowl 23 is stable and centered within the support bowl 26. An LED light panel 27 is provided on the inner side of the nano-electroplated anti-glare reflective bowl 23. The LED light panel 27 is connected to a power supply via a circuit to provide illumination.

[0048] Fixing holes 17 are provided on the side wall of the intermediate connecting frame 2 at the positions corresponding to the two bait blocks 20, and the inside of the fixing holes 17 is provided with a rotating shaft 18 for connecting the bait block 20 and the intermediate connecting frame 2. The inner ring 21 of the rear housing on one side of the two bait blocks 20 is provided with a limiting shaft 19 through the docking hole 24, and the support edge 25 on one side of the inner ring 21 of the rear housing is provided with an angle limiting hole 4 at the position corresponding to the limiting shaft 19.

[0049] A notch 7 for angle adjustment is provided on one side of the support edge 25.

[0050] The angle limiting hole 4 is composed of multiple holes connected in series. The inner diameter of each hole is larger than the outer diameter of the limiting shaft 19, and the opening between each hole is slightly smaller than the diameter of the limiting shaft 19.

[0051] The intermediate connecting frame 2 has two fixing holes 17 on its side wall, the inner diameter of which matches the outer diameter of the rotating shaft 18. One end of the rotating shaft 18 is inserted into the fixing hole 17, and the other end is inserted into the corresponding hole in the bait block 20, thereby connecting the bait block 20 to the intermediate connecting frame 2. The rotating shaft 18 is designed to rotate freely within the fixing hole 17, allowing the bait block 20 to rotate around the rotating shaft 18.

[0052] An angle limiting hole 4 is provided on the support edge 25 on one side of the inner ring 21 of the rear housing. The angle limiting hole 4 is composed of multiple holes connected in series. The inner diameter of each hole is slightly larger than the outer diameter of the limiting shaft 19 to ensure that the limiting shaft 19 can be smoothly inserted. The opening between each hole is slightly smaller than the diameter of the limiting shaft 19. This design is so that when the bait block 20 rotates to different angles, the limiting shaft 19 can be engaged in the corresponding hole, thereby realizing the angle limiting function.

[0053] The limiting shaft 19 is fixed to one side of the bait block 20 through the docking hole 24 to ensure that it will not fall off during use. A notch 7 is provided on one side of the support edge 25, and the design of the notch 7 provides sufficient space for angle adjustment.

[0054] In this embodiment of the application, when the anti-slip limiting plates 3 on both sides of the front housing 1 of the lamp body are pressed, the distance between the two anti-slip limiting plates 3 is reduced under the action of the memory elastic sheet 12, and the front housing 1 of the lamp body is aligned with the mounting hole on the ceiling and inserted; when the anti-slip limiting plates 3 are released, the memory elastic sheet 12 drives the anti-slip limiting plates 3 to automatically return to their original position, so that the downlight is fixed in the mounting hole, and the support panel 9 is in contact with the ceiling surface to ensure the stability of the lamp body.

[0055] When the left and right direction of the light-emitting surface needs to be adjusted, hold the inner ring 15 of the front housing and use the cooperation between the rotating ring 28 on its outer edge and the support ring 29 inside the front housing 1 of the lamp body to make the inner ring 15 of the front housing rotate 0-360° around the support ring 29 until the desired horizontal projection direction is achieved.

[0056] When the up and down angle of the light-emitting surface needs to be adjusted, the inner ring 21 of the rear housing is rotated by means of the connection structure between the bait blocks 20 at both ends of the support bowl 26 on one side of the inner ring 21 of the rear housing and the rotating shaft 18 in the fixing hole 17 on the side wall of the intermediate connecting frame 2. This allows the limiting shaft 19 to move within the angle limiting hole 4 of the support side 25. The notch 7 on one side of the support side 25 provides space for adjustment. When the limiting shaft 19 is inserted into the hole of the corresponding angle in the angle limiting hole 4 (because the opening between the holes is slightly smaller than the diameter of the limiting shaft 19, positioning can be achieved), the pitch angle fixation within the range of 0-30° is completed.

[0057] When the power is turned on, the LED light panel 27 emits light. The light is reflected by the nano-electroplated anti-glare reflector bowl 23 and projected out after being adjusted by the lens 8. The heat dissipation holes 6 with the trademark pattern on the back of the rear housing 5 dissipate heat to ensure stable operation of the lamp.
