Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and more particularly to a ceiling downlight. Background Technology

[0002] In recent years, the performance of LED lights has been continuously improving. Compared with traditional light sources, they have advantages in terms of lifespan, start-up time, stability, safety, and environmental friendliness. LED lights have gradually replaced traditional lighting fixtures. LED lights are classified into two types based on whether the projection direction can be adjusted: fixed LED lights and adjustable LED lights. Adjustable LED lights mainly rely on angle adjustment devices added to the fixture, allowing the lighting angle to be adjusted in multiple directions to meet users' specific lighting needs. Ceiling downlights are a type of LED light, providing ample illumination for products to achieve a good visual effect. However, as they are recessed fixtures, they have certain limitations in angle adjustment. Furthermore, to avoid light leakage, light shields are often required, resulting in a significant increase in installation space occupied by the ceiling downlights. Additionally, the light shields cannot adjust with changes in angle, preventing the full utilization of light. Summary of the Invention

[0003] The purpose of this application is to provide a ceiling downlight that can solve the above-mentioned problems existing in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On one hand, a ceiling downlight is provided, comprising: a front frame, a rotating frame, a swing frame, a light shield, and a lamp body assembly. The rotating frame is movably mounted on the front frame and can rotate relative to the front frame. The outer side of the light shield is provided with a first protrusion that engages with the inner wall of the rotating frame, and the inner side of the light shield is provided with a second protrusion that engages with the outer wall of the swing frame. The light shield is connected to the swing frame and the rotating frame respectively, so that the swing frame is installed at intervals inside the rotating frame, and the swing frame can swing relative to the rotating frame in the vertical direction through the gap between it and the rotating frame. The lamp body assembly is mounted on the swing frame.

[0006] Optionally, the swing frame has a first clearance position for the installation of the light-shielding component, and the rotating frame has a second clearance position on the side of the swing direction relative to the swing frame.

[0007] Optionally, the outer wall of the swing frame is provided with a first groove that engages with the first protrusion. The first groove is in the shape of a vertically arranged strip, and the first protrusion can move within the first groove.

[0008] Optionally, the inner wall of the rotating frame is provided with a second groove that engages with the second protrusion. The second groove is in the shape of an inclined strip, and the second protrusion can move within the second groove.

[0009] Optionally, at least two elastic buckles are provided on the outer wall of the rotating frame, and a slot is provided on the inner wall of the front frame to engage with the elastic buckles.

[0010] Optionally, the elastic buckle includes a first latching portion located outside the rotating frame and a second latching portion located inside the rotating frame, wherein the first latching portion and the second latching portion flip up and down with the rotating frame as a fulcrum.

[0011] Optionally, it also includes a pull ring, which is slidably installed on the inner wall of the rotating frame and abuts against the second locking part. When the pull ring moves downward, it abuts against the second locking part and flips downward, thereby causing the first locking part to flip upward. The first locking part flips upward until it is flush with the outer wall of the rotating frame, and the front frame disengages from the rotating frame.

[0012] Optionally, a first locking member is provided on the outer wall of the rotating frame, and a plurality of first echo grooves corresponding to the first locking member are provided on the inner wall of the front frame. When the rotating frame rotates to the point where the first locking member corresponds to the first echo groove, the first locking member engages in the first echo groove, and the first locking member impacts the side wall of the first echo groove to generate a popping sound; and / or, a second locking member is provided on the outer wall of the swing frame, and a second echo groove corresponding to the swing trajectory of the swing frame is provided on the inner wall of the rotating frame. When the swing frame swings to the point where the second locking member corresponds to the second echo groove, the second locking member engages in the second echo groove, and the second locking member impacts the side wall of the second echo groove to generate a popping sound.

[0013] Optionally, the angle at which the rotating frame rotates relative to the front frame is a, and the angle at which the swing frame swings relative to the rotating frame is b, where 0 < a ≤ 355° and 0 < b ≤ 35°.

[0014] Optionally, it also includes a front cover, which is snapped onto the bottom of the rotating frame, and the lamp body assembly is snapped onto the swing frame.

[0015] The beneficial effects of this application are as follows: Compared with the prior art, no angle adjustment mechanism is set. The up and down swing of the swing frame is achieved by the light shield, which saves the installation space inside the lamp. Moreover, the two protrusions set on the inner and outer walls of the light shield respectively engage the rotating frame and the swing frame. The light shield has both angle adjustment and light shielding functions. At the same time, it can ensure that when the swing frame swings up and down relative to the rotating frame, the light shield swings synchronously with the swing frame to achieve a light shielding effect without dead angles. In addition, the second groove is set as an inclined strip shape to guide the swing trajectory and angle of the swing frame. The first groove is set as a vertical strip shape to provide a range of motion for the first protrusion. In this way, after the swing frame swings, it can further move by the cooperation of the first protrusion and the first groove to increase the distance between the bottom edge of the swing frame and the inner wall of the rotating frame, thereby increasing the swing angle of the swing frame and realizing more swing angle adjustments.

[0029] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] like Figures 1-11As shown, this embodiment provides a ceiling downlight, including: a front frame 1, a rotating frame 2, a swing frame 3, a light-shielding member 4, and a lamp body assembly 5. The rotating frame 2 is movably mounted on the front frame 1 and can rotate relative to the front frame 1. The outer side of the light-shielding member 4 is provided with a first protrusion 401 that engages with the inner wall of the rotating frame 2, and the inner side of the light-shielding member 4 is provided with a second protrusion 402 that engages with the outer wall of the swing frame 3. The light-shielding member 4 is connected to the swing frame 3 and the rotating frame 2 respectively, so that the swing frame 3 is installed at intervals inside the rotating frame 2, and the swing frame 3 can swing relative to the rotating frame 2 in the vertical direction through the gap between it and the rotating frame 2. The lamp body assembly 5 is mounted on the swing frame 3.

[0033] Based on the above scheme, the light-shielding component 4 is arc-shaped and embedded between the swing frame 3 and the rotating frame 2. This is equivalent to connecting the swing frame 3 and the rotating frame 2 with a gap between them. The gap between the swing frame 3 and the rotating frame 2 ensures that the swing frame 3 can swing relative to each other. The size of the swing angle depends on the size of the gap between the swing frame 3 and the rotating frame 2. Therefore, the gap between the swing frame 3 and the rotating frame 2 can be adjusted by adjusting the thickness of the light-shielding component 4, thereby adjusting the size of the swing angle of the swing frame 3. The light-shielding component 4 has a first protrusion 401 symmetrically arranged on both sides of its outer surface, and a second protrusion 402 symmetrically arranged at both ends of its inner surface. To facilitate the vertically embedded assembly of the rotating frame 2 and the swing frame 3, the second protrusion 402 and the first protrusion 401 are arranged vertically, with the second protrusion 402 positioned above the first protrusion 401. This arrangement is based on the fact that the swing frame 3 is mounted on top of the rotating frame 2. The symmetrical arrangement of the two protrusions 401 and 402 ensures the stability of the connection and the smoothness of the swinging process. The light-shielding component 4 uses a double-protrusion connection to connect the swing frame 3 and the rotating frame 2, allowing it to swing along with the swing frame 3, ensuring that the light-shielding effect of the light-shielding component 4 meets the requirements and achieves a complete light-shielding effect. In this design, the light-shielding component 4, while ensuring its light-shielding effect, also functions as a connector between the swing frame 3 and the rotating frame 2. This eliminates the need for an additional angle adjustment mechanism, saving installation space for the lamp, facilitating the installation of other components, and effectively reducing manufacturing costs.

[0034] like Figure 4As shown, to ensure smoother swinging of the swing frame 3, a first clearance position is provided on the swing frame 3 for the installation of the light-shielding component 4. A second clearance position is provided on the side of the rotating frame 2 relative to the swinging direction of the swing frame 3. The first and second clearance positions are located on the same side. The first clearance position opens downwards, while the second clearance position opens upwards. The light-shielding component 4 is located between the two clearance positions. This ensures that the installation of the light-shielding component 4 is not affected by the structure of the swing frame 3 and the rotating frame 2, making installation and connection more convenient. Besides facilitating the installation of the light-shielding component 4, the main purpose of setting two clearance positions is to provide a misaligned space when the swing frame 3 swings, so that the swing frame 3 is not restricted by the inner wall of the rotating frame 2, and the adjustable range is also larger.

[0035] The first clearance position should be opened as large as possible while ensuring the structural strength of the swing frame 3. This will achieve better results for both the installation of the light shield 4 and the clearance of the swing frame 3. The second clearance position should be opened at the bottom upper part of the rotating frame 2 to ensure that the bottom of the rotating frame 2 has enough area to connect with the front frame 1.

[0036] Preferably, the outer wall of the swing frame 3 has a first groove 301 that engages with the first protrusion 401. The first groove 301 is a vertically arranged strip shape, and the first protrusion 401 can move within the first groove 301. The inner wall of the rotating frame 2 has a second groove 201 that engages with the second protrusion 402. The second groove 201 is an inclined strip shape, and the second protrusion 402 can move within the second groove 201. The first groove 301 and the second groove 201 can be used individually or together. The first example is their use individually. When only a vertical strip-shaped first groove 301 is formed on the outer wall of the swing frame 3, the initial position of the first protrusion 401 is at the bottom of the first groove 301. After the swing frame 3 swings at a certain angle, the bottom edge of the swing frame 3 abuts against the inner wall of the rotating frame 2, thus limiting the swing angle. The swing frame 3 can be dragged so that the first protrusion 401 moves upward from the bottom of the first groove 301. During the movement, a gap gradually forms between the bottom edge of the swing frame 3 and the inner wall of the rotating frame 2, allowing the swing frame 3 to swing further with a larger swing angle. The swing angle can also be adjusted by adjusting the length of the first groove 301.

[0037] When an inclined strip-shaped second groove 201 is opened only on the inner wall of the rotating frame 2, the second protrusion 402 moves within the second groove 201 when the swing frame 3 swings. The second groove 201 provides a guiding function for the second protrusion 402, and the inclination of the second groove 201 also determines the swing angle of the swing frame 3. Therefore, different inclinations of the second groove 201 can be designed to create ceiling spotlights with different swing angles. Initially, the second protrusion 402 is located at the upper end of the second groove 201. After the swing frame 3 swings, the second protrusion 402 gradually moves from the upper end to the lower end of the second groove 201. When the second protrusion 402 moves to the lower end of the second groove 201, the bottom edge of the swing frame 3 abuts against the inner wall of the rotating frame 2. The second protrusion 402 is abutted by the upper and lower inner walls of the second groove 201, which can effectively prevent the swing frame 3 from swinging in the opposite direction.

[0038] The following explanation addresses the combined use of the first groove 301 and the second groove 201. The second groove 201, in conjunction with the second protrusion 402, limits the swing trajectory and angle of the swing frame 3. After the swing of the swing frame 3 is restricted, the swing frame 3 can be further swinged a second time by the cooperation of the first groove 301 and the first protrusion 401, thereby expanding the swing angle of the swing frame 3.

[0039] In some embodiments, the two ends of the swing frame 3 extend downward to form abutment portions 302, the first groove 301 is formed on the abutment portions 302, and the inner wall of the rotating frame 2 is provided with a support portion 202 that can support the abutment portions 302. The abutment surfaces of the support portion 202 and the abutment portions 302 are both arc-shaped.

[0040] To ensure the stability of the swing frame 3 during the swing process, a locking component is added between the swing frame 3 and the rotating frame 2. Whether in the initial state or the swing state, the relative position between the swing frame 3 and the rotating frame 2 can be locked by the locking component, so as to avoid relative displacement between the swing frame 3 and the rotating frame 2 under any circumstances, thus ensuring the stable illumination effect of the ceiling downlight.

[0041] Optionally, at least two elastic buckles 203 are provided on the outer wall of the rotating frame 2, and a slot is provided on the inner wall of the front frame 1 to engage with the elastic buckles 203. The slot on the inner wall of the front frame 1 is an annular slot, so that when the rotating frame 2 rotates relative to the front frame 1, the elastic buckles 203 can engage with the slot, thereby ensuring the stable connection between the front frame 1 and the rotating frame 2.

[0042] To further improve the locking stability of the rotating frame 2 and the front frame 1, three elastic buckles 203 are provided and are evenly distributed on the outside of the rotating frame 2. The three elastic buckles 203 are triangularly distributed on the plane. The reason for preferably providing three elastic buckles 203 is that the triangular locking is more stable and reliable.

[0043] Specifically, such as Figure 7 As shown, the elastic buckle 203 includes a first latching part 2031 located on the outside of the rotating frame 2 and a second latching part 2032 located on the inside of the rotating frame 2. The first latching part 2031 and the second latching part 2032 rotate up and down with the rotating frame 2 as the fulcrum. A through hole is opened on the rotating frame 2, through which part of the elastic buckle 203 can pass. The lower wall of the through hole is the fulcrum for the rotation of the elastic buckle 203. In the installed state, the first latching part 2031 is downward and the second latching part 2032 is upward. At this time, the first latching part 2031 is engaged in the slot of the front frame 1, so that the rotating frame 2 is locked on the front frame 1. When it is necessary to disassemble, by moving the second latching part 2032 downward, the first latching part 2031 is rotated upward until it disengages from the slot, and then the rotating frame 2 is removed.

[0044] In some embodiments, such as Figure 6 As shown, it also includes a pull ring 8, which is slidably installed on the inner wall of the rotating frame 2 and abuts against the second locking part 2032. When the pull ring 8 moves downward, it abuts against the second locking part 2032 and flips downward, thereby causing the first locking part 2031 to flip upward. The first locking part 2031 flips upward until it is flush with the outer wall of the rotating frame 2, and the front frame 1 disengages from the rotating frame 2. An abutment hole is provided on the pull ring 8, which is fitted onto the second locking part 2032. When the pull ring 8 is pulled downward, it abuts against the second locking part 2032 through the abutment hole and flips downward, thereby causing the first locking part 2031 to flip upward. After the pull ring 8 moves into place, the first locking part 2031 is completely in the through hole, and the front frame 1 can disengage from the rotating frame 2. When the pull ring 8 is released, the elastic buckle 203 will return to its original state under its own elastic force.

[0045] To facilitate pulling the pull ring 8, a pull hole of finger size is provided on the pull ring 8. The pull ring 8 can be pulled by placing the finger against the pull hole.

[0046] Two symmetrical track sections 9 are provided on the inner wall of the rotating frame 2. Track grooves are provided on opposite sides of the track sections 9. The pull ring 8 is located between the two track sections 9. Both sides of the pull ring 8 are provided with sliding pieces that cooperate with the track grooves. The sliding direction of the pull ring 8 is limited by the cooperation between the sliding pieces and the track grooves. In addition, a limiting part can be provided at the bottom of the rotating frame 2 to limit the sliding of the pull ring 8 and prevent the pull ring 8 from sliding beyond the preset range.

[0047] In the above-mentioned ceiling downlight, a pull ring 8 can be set to complete the disassembly of the front frame 1 and the rotating frame 2. Pulling the pull ring 8 will cause one of the elastic clips 203 of the rotating frame 2 to disengage from the slot of the front frame 1, and the front frame 1 will be partially disengaged from the rotating frame 2. Then, the positions of the other clips can be adjusted to complete the disassembly.

[0048] Alternatively, a linkage can be set up. Taking three elastic buckles 203 as an example, the linkage abuts against the three second snap-fit ​​parts 2032 respectively and is connected to the pull ring 8. When the pull ring 8 is pulled down, the linkage simultaneously abuts against the three second snap-fit ​​parts 2032 and flips them down. The three first snap-fit ​​parts 2031 flip up accordingly, so that the three elastic buckles 203 can be disengaged from the slot at the same time. In this way, the front frame 1 can be moved horizontally and disengaged from the rotating frame 2.

[0049] To enhance the sense of ceremony during the rotation and swaying of the ceiling spotlights, a first locking member 205 is provided on the outer wall of the rotating frame 2, and a plurality of first echo grooves 101 corresponding to the first locking member 205 are provided on the inner wall of the front frame 1. When the rotating frame 2 rotates to the point where the first locking member 205 corresponds to the first echo groove 101, the first locking member 205 is engaged in the first echo groove 101, and the first locking member 205 impacts the side wall of the first echo groove 101 to create a popping sound. A second locking member 303 is provided on the outer wall of the swing frame 3, and a second echo groove 204 corresponding to the swing trajectory of the swing frame 3 is provided on the inner wall of the rotating frame 2. When the swing frame 3 swings to the point where the second locking member 303 corresponds to the second echo groove 204, the second locking member 303 is engaged in the second echo groove 204, and the second locking member 303 impacts the side wall of the second echo groove 204 to create a popping sound. In this design, when the rotating frame 2 rotates, the first locking piece 205 collides with the first echo groove 101 and makes a popping sound. When the swing frame 3 swings, the second locking piece 303 collides with the second echo groove 204 and makes a popping sound. In this way, whether rotating or swinging, a relative popping sound will be generated to remind the user that the rotation or swing is effective, and at the same time, it can enhance the sense of ritual of use.

[0050] It is worth mentioning that the second echo groove 204 and the second locking component 303 are designed to produce a popping sound during the swinging process. Therefore, the second echo groove 204 needs to be adapted to the swinging trajectory of the swing frame 3. In other words, the second echo groove 204 is arc-shaped. Moreover, considering that the swing frame 3 can further adjust the swing angle, the second echo groove 204 needs to increase its slotting area in the vertical direction to ensure that the swing frame 3 can still produce a popping sound after a second swing.

[0051] As one specific solution in this embodiment, such as Figure 8As shown, the rotating frame 2 rotates at an angle 'a' relative to the front frame 1, and the swinging frame 3 swings at an angle 'b' relative to the rotating frame 2, where 0 < a ≤ 355° and 0 < b ≤ 35°. Specifically, the rotation angle 'a' = 355° and the swinging angle 'b' = 35°; or, depending on different design requirements, the rotation angle 'a' = 180° and the swinging angle is 30°.

[0052] Optionally, such as Figure 10 As shown, the ceiling downlight also includes a front cover 7, which is snapped onto the bottom of the rotating frame 2, and the lamp body assembly 5 is snapped onto the swing frame 3.

[0053] like Figure 9 As shown, in order to ensure the heat dissipation effect of the lamp body assembly 5, a heat sink 6 is also provided. The heat sink 6 is located on the top of the lamp body assembly 5 and is exposed outside the swing frame 3.

[0054] All components of the ceiling downlight described in this embodiment are standard modular structures, and the components are connected by snap-fit, enabling quick installation and replacement of parts.
