Description

Technical Field

[0001] This application relates to the technical field of lamps, and specifically to a rotatable adjustment structure for downlights. Background Art

[0002] A downlight refers to a lamp with a screw base lamp holder that can directly install incandescent lamps or energy-saving lamps. A downlight is a type of recessed ceiling lighting fixture that projects light downward. This recessed fixture inside the ceiling has all the light projected downward, belonging to direct light distribution. Different reflectors, lenses, louvers, and bulbs can be used to achieve different lighting effects. Downlights do not take up space and can add a soft atmosphere to the space. If you want to create a warm feeling, you can try installing multiple downlights to reduce the sense of space compression. They are generally used more in hotels, homes, and cafes.

[0003] When installing a downlight, in order to change the lighting angle, the structure of the downlight needs to be adjusted to change the lighting position. The existing adjustment methods mostly involve swinging the lamp left and right to change the angle between the lamp and the radiator on the lamp. This adjustment method will cause a large angular gap at the connection between the lamp and the radiator, making it easy for external debris or mosquitoes to enter the ventilation interior, and there are certain deficiencies.

[0004] Therefore, this application provides a rotatable adjustment structure for downlights to solve the above problems. Utility Model Content

[0005] This application provides a rotatable adjustment structure for downlights, aiming to solve the problems in the background art that the existing adjustment methods for downlights mostly involve swinging the lamp left and right to change the angle between the lamp and the radiator on the lamp. This adjustment method will cause a large angular gap at the connection between the lamp and the radiator, making it easy for external debris or mosquitoes to enter the ventilation interior, and there are certain deficiencies.

[0006] To achieve the above object, this application provides the following technical solution: A rotatable adjustment structure for downlights, including a radiator and a lamp fixedly installed inside the radiator, and a rotatable adjustment mechanism adapted to the radiator is installed on the lamp:

[0007] The rotation adjustment mechanism includes a support base movably installed on the lamp at the opposite end of the radiator and inserted into the radiator. At the end of the support base away from the lamp, an adjustment base is rotatably installed. On the surface of the support base opposite to the adjustment base, an upper adjustment ring is fixedly installed. On the surface of the upper adjustment ring opposite to the adjustment base, a retaining ring arranged in a slope is fixedly installed. On the surface of the adjustment base opposite to the support base, a lower adjustment ring is fixedly installed. On the adjustment base and on the lower adjustment ring, a slot adapted to the retaining ring is provided. In this way, when installing the downlight, rotate the radiator. The radiator drives the lamp and the support base to rotate on the adjustment base. Since the retaining ring is arranged in a slope, when the radiator rotates, it will rotate along the path of the slot arranged in the slope of the retaining ring. On the premise that the horizontal direction of the adjustment base remains horizontal and consistent with the ceiling gypsum board ceiling, the radiator will drive the lamp to rotate in an inclined manner, so as to complete the adjustment of the irradiation angle of the lamp while ensuring that the interface between the radiator and the support base is completely sealed. The operation is convenient and fast. Compared with the existing open-adjustment downlights, it is not easy for mosquitoes and impurities to enter the interior, can reduce the damage of the downlight, and improve the service life of the equipment.

[0008] Preferably, in order to fix the lamp, a fixing base is installed on the upper buckle of the lamp, and an installation hole for fixedly connecting with the interior of the radiator is provided on the fixing base. This enables the irradiation angle of the lamp to be changed when the angle of the radiator is adjusted.

[0009] Preferably, in order to fix the radiator and the support base, two symmetrically arranged pins are fixedly installed on the support base, and two jacks adapted to the pins are symmetrically provided in the radiator. Thus, the support base, the lamp on the support base, and the radiator are integrated, which is convenient for adjustment and installation.

[0010] Preferably, in order to focus the light, a lamp cup adapted to the lamp is fixedly installed in the adjustment base. It can also change the light color, and the adjustment is flexible and convenient.

[0011] Preferably, in order to fix the adjustment base, the adjustment structure further includes a connection mechanism. The connection mechanism includes two symmetrically arranged elastic pieces fixedly installed on the outer side wall of the adjustment base and a pressing ring fixedly installed on the adjustment base for fitting against the outer wall surface of the ceiling. The elastic pieces clamp the preset hole in the ceiling, and the pressing ring presses against the ceiling gypsum board ceiling from the bottom, which is convenient for disassembly and assembly.

[0012] Preferably, in order to stabilize the adjustment base, a number of anti-slip teeth are evenly provided on the two elastic pieces. The anti-slip teeth are frictionally engaged with the side of the ceiling gypsum board, making it more stable.

[0013] For this adjustment structure, when installing the downlight, rotate the radiator. The radiator drives the lamp and the support base to rotate on the adjustment base. Since the retaining ring is set with a slope, when the radiator rotates, it will rotate along the slot path set on the slope of the retaining ring. On the premise that the horizontal direction of the adjustment base remains level with the ceiling gypsum board ceiling, the radiator will drive the lamp to rotate in an inclined manner, so as to complete the adjustment of the irradiation angle of the lamp while ensuring that the interface between the radiator and the support base is completely sealed. The operation is convenient and fast. Compared with the existing open-adjustable downlights, it is not easy for mosquitoes and impurities to enter the interior, which can reduce the damage of the downlights and improve the service life of the equipment.

[0014] For this adjustment structure, after inserting the radiator and the adjustment base into the ceiling, the elastic piece clamps the preset hole in the ceiling, and the abutting ring abuts against the ceiling gypsum board ceiling from the bottom, so that the downlight is completely and flatly clamped into the preset hole, with good fixing effect, without damaging the gypsum board structure, and is convenient for disassembly and assembly.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Embodiment 1

[0023] This embodiment provides a rotatable adjustment structure for a downlight, as Figures 1-4 shown. The adjustment structure includes a radiator 1 and a lamp 2 fixedly installed in the radiator 1. A rotatable adjustment mechanism 3 adapted to the radiator 1 is installed on the lamp 2:

[0024] The rotatable adjustment mechanism 3 includes a support base 31 movably installed on the lamp 2 at the opposite end of the radiator 1 and inserted into the radiator 1. A regulating base 32 is rotatably installed at the end of the support base 31 away from the lamp 2. An upper adjustment ring 33 is fixedly installed on the opposite surface of the support base 31 to the regulating base 32. A clamping ring 34 arranged in a slope is fixedly installed on the opposite surface of the upper adjustment ring 33 to the regulating base 32. A lower adjustment ring 35 is fixedly installed on the opposite surface of the regulating base 32 to the support base 31. A slot 36 adapted to the clamping ring 34 is opened on the regulating base 32 on the lower adjustment ring 35.

[0025] During use, when installing the downlight, rotate the radiator 1. The radiator 1 drives the lamp 2 and the support base 31 to rotate on the regulating base 32. Since the clamping ring 34 is arranged in a slope, when the radiator 1 rotates, it will rotate along the path of the slot 36 arranged along the slope of the clamping ring 34. On the premise that the horizontal direction of the regulating base 32 remains horizontal and consistent with the ceiling gypsum board ceiling, the radiator 1 will drive the lamp 2 to perform an inclined rotation, so as to complete the adjustment of the irradiation angle of the lamp 2 while ensuring the completely sealed state at the interface between the radiator 1 and the support base 31. The operation is convenient and fast. Compared with the existing open-adjustment downlights, it is not easy for mosquitoes and impurities to enter the interior, which can reduce the damage of the downlight and improve the service life of the equipment.

[0026] Specifically, a fixing base 37 is installed on the upper buckle of the lamp 2, and an installation hole 38 for fixedly connecting with the interior of the radiator 1 is opened on the fixing base 37. During use, insert the fixing base 37 into the radiator 1 and align the installation hole 38 thereon, and then fix it with screws. Subsequently, rotate and buckle the lamp 2 on the fixing base 37 to complete the fixation of the lamp 2, so that the irradiation angle of the lamp 2 can be changed when the angle of the radiator 1 is adjusted.

[0027] More specifically, two symmetrically arranged pins 39 are fixedly installed on the support base 31, and two jacks 310 adapted to the pins 39 are symmetrically opened in the radiator 1. During use, push the support base 31 upward, align the pins 39 with the jacks 310 in the radiator 1 and insert them, so that the support base 31, the lamp 2 on the support base 31 and the radiator 1 become an integral body, which is convenient for adjustment and installation.

[0028] Furthermore, a lamp cup 4 adapted to the lamp 2 is fixedly installed in the regulating base 32. During use, the lamp 2 emits light, and the lamp cup 4 focuses the light, thus playing a role in concentrating the light. And by changing the color of the lamp cup 4, the color of the light can also be changed, and the adjustment is flexible and convenient.

[0029] Embodiment 2

[0030] Different from Embodiment 1, when installing the downlight into the preset hole in the gypsum board ceiling, connecting by screws will damage the strength of the gypsum board. Therefore, the adjusting structure further includes a connecting mechanism 5. The connecting mechanism 5 includes two elastic pieces 51 fixedly installed on the outer side wall of the adjusting seat 32 and arranged symmetrically, and a resisting ring 52 fixedly installed on the adjusting seat 32 for fitting against the outer wall surface of the ceiling. During use, after the radiator 1 and the adjusting seat 32 are inserted into the ceiling, the elastic pieces 51 catch the preset hole in the ceiling, and the resisting ring 52 abuts against the gypsum board ceiling of the ceiling from the bottom, so that the downlight is completely and flatly clamped into the preset hole, with good fixing effect, without damaging the gypsum board structure, and is convenient for disassembly and assembly.

[0031] Specifically, a number of anti-slip teeth 53 are evenly formed on the two elastic pieces 51. During use, after the radiator 1 and the adjusting seat 32 are inserted into the ceiling, the elastic pieces 51 catch the preset hole in the ceiling, and the anti-slip teeth 53 on the elastic pieces 51 are frictionally engaged with the side of the gypsum board of the ceiling, making it more stable.

[0032] As described above, only the preferred specific embodiments of the present application are provided, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application, according to the technical solutions and concepts of the present application, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present application.
