Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, specifically to a lighting fixture that combines focusing and angle adjustment. Background Technology
[0002] In the field of modern lighting, recessed ceiling lights are commonly used embedded lighting devices in homes, commercial spaces, and industrial areas. Their focus and angle adjustment functions are crucial for meeting the lighting needs of different scenarios. Whether it's creating ambiance in a living room, displaying goods in a shopping mall, or providing accent lighting in a conference room, recessed ceiling lights need to be able to flexibly adjust the range and direction of light according to the actual situation.
[0003] In existing technologies, the focusing mechanism of ceiling downlights generally adopts a vertical adjustment method. For example, some ceiling downlights expand the illumination range by extending the lens outward or narrowing the illumination range by moving the lens cover backward. While this adjustment method can achieve focusing to a certain extent, it has significant limitations. From the perspective of ease of operation, since ceiling downlights are installed inside the ceiling, the adjustment process often requires tools and both hands, making it very inconvenient. Moreover, the adjustment precision is difficult to control, easily leading to over- or under-adjustment. More importantly, this vertical adjustment method causes the lens to protrude outward. For ceiling downlights, a protruding lens disrupts the overall flatness and aesthetics of the ceiling, clashing with the ceiling's decorative style. Simultaneously, a protruding lens is prone to dust accumulation, increasing cleaning difficulty, and is susceptible to accidental bumps and scratches during daily use, increasing the risk of lens damage and shortening the lifespan of the ceiling downlight.
[0004] Furthermore, existing ceiling downlights offer limited adjustment functions, mostly only allowing for either focus or angle adjustment. Even those that claim to offer both functions simultaneously have very limited angle adjustment ranges, failing to meet the lighting needs of large exhibition halls, conference rooms, and other venues requiring illumination from different areas and angles. In these spaces, where ceiling downlights need to illuminate a wider area and at more angles, this limitation of existing ceiling downlights becomes particularly pronounced, making it difficult to meet diverse lighting requirements.
[0005] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content
[0006] This invention overcomes the shortcomings of the above-mentioned technologies and provides a lamp that combines focusing and angle adjustment.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A lamp with both focusing and angle adjustment functions includes an outer cover and a lamp body rotatably connected within the outer cover. The lamp body comprises a heat sink housing, a mounting bracket movably connected vertically to the lower end of the heat sink housing, a lens assembly rotatably connected within the mounting bracket, and an outer frame hinged to the lower end of the mounting bracket. The outer frame is rotatably connected within the outer cover. A blocking structure is provided between the outer frame and the outer cover to fix them circumferentially after they have rotated to their respective positions. The heat sink housing is vertically connected to the upper end of the lens assembly via a limiting and guiding structure. The lower end of the lens assembly is rotatably disposed within the outer frame and extends downwards into the outer cover. Rotating the lens assembly drives the heat sink housing to move vertically relative to the mounting bracket, the outer frame, and the lens assembly. Driving the mounting bracket causes the lens assembly to swing relative to the outer frame. The mounting bracket, the heat sink housing, and the outer frame are circumferentially fixed.
[0008] Furthermore, the blocking structure includes a first baffle plate disposed on the outer side wall of the lower end of the outer frame and a second baffle plate disposed on the inner wall of the outer cover for blocking and limiting cooperation with the first baffle plate.
[0009] Furthermore, the limiting guide structure includes an internal thread provided on the inner wall of the radiator housing and an external thread provided on the lens assembly for threaded connection with the internal thread.
[0010] Furthermore, the mounting bracket includes an upwardly extending guide strip, and the outer side of the radiator housing is provided with a guide groove. The guide strip can be movably inserted into the guide groove to fix the mounting bracket and the radiator housing circumferentially.
[0011] Furthermore, the guide strip is provided with a first hook, the guide groove is provided with a second hook for engaging with the first hook, the outer wall of the radiator housing is also provided with a first blocking surface, and the mounting bracket is provided with a second blocking surface.
[0012] Furthermore, the mounting bracket is symmetrically provided with a first connecting ear at its lower end, and a connecting shaft is provided on the first connecting ear. The outer frame is provided with a second connecting ear, and a connecting hole with an upper opening is provided on the second connecting ear. The connecting shaft is rotatably connected to the connecting hole.
[0013] Furthermore, the mounting bracket includes symmetrically arranged third hooks, and the lens assembly includes an annular groove into which the third hooks engage and move.
[0014] Furthermore, the outer cover is provided with an inner ring, and the outer frame includes a fourth hook and an outer ring disposed at the lower end of the fourth hook. The fourth hook abuts against the upper wall of the inner ring, and the outer ring abuts against the lower wall of the inner ring. The diameter of the outer ring is larger than the diameter of the inner ring.
[0015] Furthermore, the lens assembly includes a connecting cylinder, a lens installed inside the connecting cylinder, and a lens element located at the lower end of the lens and installed inside the connecting cylinder.
[0016] Furthermore, the lower end of the connecting cylinder is provided with a grip portion, and the grip portion is provided with anti-slip stripes.
[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. Since ceiling spotlights are typically installed inside the ceiling or on stage supports at a high location, their heat sink housings are all positioned upwards, concealed within the ceiling or facing the top of the stage support. This design provides a light fixture that combines focusing and angle adjustment. By incorporating a limiting guide structure, the user can directly rotate the lens assembly from inside the housing to drive the heat sink housing up and down for focusing. During focusing, the lens assembly does not protrude relative to the housing, thus preserving the flatness of the ceiling and effectively avoiding the risk of lens exposure, damage, and dust accumulation, while also maintaining the overall aesthetics of the ceiling.
[0018] 2. The main body of the lamp in this case can rotate relative to the outer cover, and in conjunction with the mounting bracket, it drives the lens assembly to swing relative to the outer frame within the cover, achieving a large-angle, wide-range, and all-around adjustment of the illumination angle. For ceiling downlights, this adjustment method can meet the lighting needs of different areas, easily achieving whether illuminating wall decorations or highlighting a specific area.

[0028] It should be noted that the lighting fixture described in this case is a ceiling downlight, which has a cylindrical structure common in the art. The focus of protection sought in this case is the structure for focusing and adjusting the beam angle. Therefore, circuit boards, LEDs, and other related components not mentioned are not shown in the accompanying drawings. However, the lighting fixture in this case includes all the components that a ceiling downlight should have. For other corresponding components required by the lighting fixture in this case, those skilled in the art can design and implement them by referring to the corresponding structures in the prior art, so they will not be described in detail.
[0029] like Figures 1 to 8As shown, this invention provides a luminaire that combines focusing and angle adjustment, including an outer cover 100 and a luminaire body 200 rotatably connected within the outer cover 100. Specifically, the outer cover 100 has torsion spring connecting ears on both sides for easy installation and disassembly of the luminaire. The luminaire body 200 includes a heat sink housing 1, a mounting bracket 2 vertically connected to the lower end of the heat sink housing 1, a lens assembly 3 rotatably connected within the mounting bracket 2, and an outer frame 4 hinged to the lower end of the mounting bracket 2. Considering cost and ease of production, while ensuring a certain degree of elasticity in the components, the mounting bracket 2 and the outer frame 4 are integrally injection molded from plastic material. The mounting bracket 2 is used to install and support the lens assembly 3, while the outer frame 4 rotatably engages with the outer cover 100 and is hinged to the mounting bracket 2. That is, a wide range of illumination angle adjustment for the lens assembly 3 can be achieved through a combination of swinging and rotating movements. The outer frame 4 is rotatably connected to the outer cover 100. A blocking structure is provided between the outer frame 4 and the outer cover 100 to fix them circumferentially after they have rotated to their respective positions. This ensures that when the outer frame 4 is rotated relative to the outer cover 100, the outer frame 4 and the outer cover are circumferentially fixed by the blocking structure, allowing the lens assembly 3 to rotate relative to the outer frame 4. The radiator housing 1 is connected to the upper end of the lens assembly 3 via a limiting guide structure, enabling the focusing of the lamp. The lower end of the lens assembly 3 is rotatably disposed within the outer frame 4 and extends downwards into the outer cover 100. Rotating the lens assembly 3 drives the radiator housing 1 to move up and down relative to the mounting bracket 2, the outer frame 4, and the lens assembly 3, thereby enabling the focusing of the lamp. Driving the mounting bracket 2 causes the lens assembly 3 to swing relative to the outer frame 4, thereby adjusting the illumination angle of the lamp. Specifically, the mounting bracket 2, the radiator housing 1, and the outer frame 4 are circumferentially fixed. The circumferential fixation mentioned in this case refers to two or more objects being relatively fixed in the circumferential direction, that is, rotating synchronously when rotating.
[0030] As described above, this invention, by setting a limiting and guiding structure, allows the user to directly rotate the lens assembly 3 from inside the outer cover 100, thereby driving the heat sink housing 1 to move up and down relative to the mounting bracket 2, the outer frame 4, and the lens assembly 3. That is, the mounting bracket 2, the outer frame 4, the lens assembly 3, and the heat sink housing 1 are relatively fixed in the vertical direction. When the user rotates the lens assembly 3 in one direction—clockwise or counterclockwise, preferably clockwise in this invention—after the lens assembly 3 drives the outer frame 4 to rotate relative to the outer cover 100 to its position, the outer frame 4 and the outer cover 100 are circumferentially fixed by the limiting structure. Continuing to rotate the lens assembly 3 at this point can drive the heat sink housing 1 to move upwards, thereby achieving focusing of the lamp. Conversely, rotating the lens assembly 3 in the other direction, i.e., counterclockwise, can drive the heat sink housing 1 to move downwards to reset, achieving focusing. The lighting fixture with this structure does not change the appearance between the lens assembly and the outer cover after focusing. That is, the lens assembly 3 will not extend downward relative to the outer cover 100, because the heat sink end is generally hidden in the ceiling or bracket, so it does not affect the aesthetics.
[0031] Secondly, by rotating the main body 200 relative to the outer cover 100, that is, when the user does not focus the lamp or needs to adjust the illumination angle after focusing, under normal circumstances, the mounting bracket 2, the heat sink shell 1, the outer frame 4, and the lens assembly 3 are circumferentially fixed and can be regarded as a whole. The main body 200 can rotate relative to the outer cover 200. By rotating the main body 200, and at the same time cooperating with the mounting bracket 2 to drive the lens assembly 3 to swing relative to the outer frame 4 within the outer cover 100, the illumination angle can be adjusted, that is, physically adjusted. Through the cooperation of the two, a large-angle, wide-range, all-round illumination angle adjustment can be achieved, with an angle adjustment range of nearly 360 degrees, which can meet all-round lighting needs. The lamp in this case not only achieves convenient and stable focusing function, but also flexibly adjusts the illumination angle, while avoiding the drawbacks of lens protrusion, improving the practicality and aesthetics of the ceiling downlight, and making it more suitable for the ceiling installation environment.
[0032] like Figures 1-3 , Figure 5 , Figure 6As shown, specifically, the blocking structure includes a first baffle 41 disposed on the lower outer wall of the outer frame 4 and a second baffle 101 disposed on the inner wall of the outer cover 100 for blocking and limiting cooperation with the first baffle 41. When the outer frame 4 rotates relative to the outer cover 100, the first baffle 41 rotates with the outer frame 4. When the first baffle 41 rotates to contact the second baffle 101, the two block each other, limiting the outer frame 4 from further rotation, thus achieving circumferential fixation between the outer frame 4 and the outer cover 100. This simple blocking structure achieves limiting through the blocking cooperation of the first baffle 41 and the second baffle 101, which is convenient for manufacturing. In specific implementation, to maximize the range of rotation, the size of the first baffle 41 and the second baffle 101 can be minimized, making the rotation of the outer frame 4 relative to the outer cover 100 closer to 360 degrees, thereby improving the flexibility of the lamp angle adjustment and better adapting to different lighting needs. At the same time, this small baffle structure occupies little space in the limited internal space of the lamp and will not affect the installation and operation of other components.
[0033] Specifically, refer to Figures 1-4 ,、 Figure 7 As shown, the limiting and guiding structure of this invention includes an internal thread 11 on the inner wall of the radiator housing 1 and an external thread 311 on the lens assembly 3 for threaded connection with the internal thread 11. This threaded connection makes the focusing adjustment process convenient and stable, and can accurately control the vertical movement distance of the radiator housing 1, ensuring the accuracy of focusing and meeting the precise requirements of the lamp for different illumination ranges. Secondly, the structure is simple, requiring no complex parts, reducing production costs, and is suitable for mass production of ceiling downlights. At the same time, the threaded structure has self-locking properties, and can be stably maintained in the adjusted position after focusing, without changing due to external vibration or lamp shaking. When the lens assembly 3 is rotated, the external thread 311 on the lens assembly 3 interacts with the internal thread 11 on the inner side of the radiator housing 1. Since the radiator housing 1 is circumferentially fixed to the mounting bracket 2 and the outer frame 4, and the lens assembly 3 can rotate relative to the mounting bracket 2 and the outer frame 4, the rotation of the lens assembly 3 is converted into the vertical movement of the radiator housing 1, thereby achieving focusing.
[0034] Reference Figures 1-4 , Figure 8 As shown, the mounting bracket 2 further includes an upwardly extending guide strip 21, and a guide groove 12 is provided on the outer side of the radiator housing 1. The guide strip 21 is movably inserted into the guide groove 12 to fix the mounting bracket 2 and the radiator housing 1 circumferentially. Simultaneously, when the radiator housing 1 moves up and down relative to the mounting bracket 2, the guide strip 21 slides along the guide groove 12, providing guidance for the relative movement of the two, ensuring the stability of the adjustment, avoiding deviation or jamming during movement, and making the focusing operation of the lamp more smooth. The guiding structure of this invention is simple and compact, suitable for the limited installation space of the lamp.
[0035] Furthermore, continue to refer to Figures 1-4 , Figure 8 As shown, a first hook 211 is provided on the guide strip 21, and a second hook 121 for engaging with the first hook 211 is provided in the guide groove 12. Simultaneously, a first blocking surface 13 is provided on the outer wall of the radiator housing 1, and a second blocking surface 22 is provided on the mounting bracket 2. This design effectively limits the maximum upward movement of the radiator housing 1 through the engagement of the first hook 211 and the second hook 121, preventing damage caused by over-adjustment and avoiding detachment, thus ensuring the stability of the internal structure of the lamp. Furthermore, the engagement of the first blocking surface 13 and the second blocking surface 22 limits the maximum downward movement of the radiator housing 1, further preventing over-adjustment, ensuring the lifespan of the lamp and the safety of adjustment, and avoiding impact on lighting effects due to over-adjustment. When the radiator housing 1 moves upward, the first hook 211 and the second hook 121 gradually approach each other. When the movement reaches its maximum stroke, the first hook 211 and the second hook 121 engage, restricting the radiator housing 1 from continuing to move upward. When the radiator housing 1 moves downward toward the mounting bracket 2, the first blocking surface 13 and the second blocking surface 22 gradually approach each other. When the movement reaches its maximum stroke, the two surfaces block each other, restricting the radiator housing 1 from continuing to move downward. This limiting structure can prevent damage to components due to over-focusing and can also effectively prevent the radiator housing 1 from becoming loose.
[0036] Reference Figures 1-3 , Figure 5 , Figure 8 As shown, this is the preferred hinge structure of the mounting bracket 2 and the outer frame 4 in this case. A first connecting ear 23 is symmetrically arranged at the lower end of the mounting bracket 2, and a connecting shaft 231 is provided on the first connecting ear 23. A second connecting ear 42 is provided on the outer frame 4, and a connecting hole 421 with an open upper end is provided on the second connecting ear 42. The connecting shaft 231 is rotatably connected to the connecting hole 421, thereby realizing the swing connection between the mounting bracket 2 and the outer frame 4, that is, realizing the swing of the lens module 3 to adjust the illumination angle of the lamp. In specific implementation, the positions of the first connecting ear 23 and the second connecting ear 42 are interchangeable; that is, the first connecting ear 23 can be located on the outer frame 4, and the second connecting ear 42 can be located on the mounting bracket 2, both achieving the same hinge effect. In specific implementation, the second connecting ear 42 is preferably made of an elastically deformable material, such as plastic, and the upper end of the connecting hole 421 is open to facilitate the assembly and disassembly between the outer frame 4 and the mounting bracket 2.
[0037] Reference Figures 1-3 , Figure 5 , Figure 7As shown, the mounting bracket 2 includes symmetrically arranged third hooks 24, and the lens assembly 3 includes an annular groove 312 into which the third hooks 24 engage and move. The engagement of the third hooks 24 and the annular groove 312 enables a detachable connection between the mounting bracket 2 and the lens assembly 3. When the lens assembly 3 rotates relative to the mounting bracket 2, the third hooks 24 slide within the annular groove 312, ensuring the stability of their relative rotation. This connection structure ensures the stability of the lens assembly 3 during rotational focusing, making the focusing operation smoother and more precise.
[0038] Reference Figures 1-3 , Figure 5 , Figure 6 As shown, further, an annular inner ring 102 is provided inside the outer cover 100. The outer frame 4 includes a fourth hook 43 and an annular outer ring 44 disposed at the lower end of the fourth hook 43. The fourth hook 43 abuts against the upper wall surface of the annular inner ring 102, and the annular outer ring 44 abuts against the lower wall surface of the annular inner ring 102. The diameter of the annular outer ring 44 is larger than the diameter of the annular inner ring 102. The fourth hook 43 and the annular outer ring 44 abut against the upper and lower walls of the annular inner ring 102 respectively, realizing the connection and fixation between the outer frame 4 and the outer cover 100 in the longitudinal direction, preventing the outer frame 4 from falling out of the outer cover 100, and ensuring the overall structural stability of the lamp. At the same time, the outer frame 4 can rotate relative to the outer cover 100, and the fourth hook 43 and the annular outer ring 44 rotate together with the outer frame 4 to ensure the stability of the rotation process. In specific implementation, in order to improve the stability of the connection between the outer frame 4 and the outer cover 100 and the stability during rotation, preferably, at least two fourth hooks 43 are provided.
[0039] Furthermore, referring to Figures 1-4 , Figure 7 As shown, the lens assembly 3 of this invention includes a connecting cylinder 31, a lens 32 installed within the connecting cylinder 31, and a lens element 33 located at the lower end of the lens 32 and installed within the connecting cylinder 31. The connecting cylinder 31 serves as the main structure of the lens assembly 3, providing a mounting carrier for the lens 32 and lens element 33. In this embodiment, external threads 311 and annular grooves 312 are both provided on the connecting cylinder 31. Integrating the external threads 311 and annular grooves 312 onto the connecting cylinder 31 makes the lens assembly 3 structure more compact, facilitates cooperation with other components, and helps save internal space in the lamp, reducing the overall volume.
[0040] Furthermore, a grip 313 is provided at the lower end of the connecting cylinder 31, and the grip 313 is provided with anti-slip stripes 3131. Since ceiling downlights are generally installed on the ceiling or stage supports, users need to look up and reach out to adjust the lights. By gripping the grip 313, they rotate the connecting cylinder 31, which in turn rotates the lens assembly 3 to achieve focusing. The anti-slip stripes 3131 increase the friction between the hand and the grip 313, preventing slippage during rotation in confined spaces.
[0041] As stated above, this case protects a lighting fixture that combines focusing and angle adjustment, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
