Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a front-adjustable downlight. Background Technology

[0002] A downlight is a light fixture embedded in a ceiling or other mounting surface. Existing downlights include a face ring, a heat sink, and a light source. The face ring is rotatably connected to the heat sink and has a light-emitting cavity. The light source is located within the heat sink and partially housed within the light-emitting cavity. An adjustment mechanism is located at the outer connection between the face ring and the heat sink, used to adjust the rotation angle of the heat sink, thereby adjusting the light-emitting angle of the light source. Because most of the downlight's main body is hidden within the ceiling, and the adjustment mechanism is located at the outer connection between the face ring and the heat sink, adjusting the light-emitting angle requires removing the entire downlight from the ceiling, adjusting it, and then reinstalling it, which is very inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a front-mounted adjustable downlight to solve the problem that the adjustment structure of existing downlights is located at the connection between the face ring and the heat sink, and the entire downlight needs to be removed from the ceiling when the light emission angle of the light source needs to be adjusted, which is very inconvenient.

[0004] This utility model is achieved through the following technical solution:

[0005] A front-mounted adjustable downlight includes a face ring assembly, a heat dissipation assembly, and a light source. The face ring assembly is rotatably connected to the heat dissipation assembly and has a light emission cavity. The light source is disposed on the heat dissipation assembly and partially housed within the light emission cavity. The light emission cavity is provided with a toggle member rotatably connected to the heat dissipation assembly. The toggle member can move relative to the face ring assembly, causing the heat dissipation assembly to rotate relative to the face ring assembly.

[0006] Furthermore, the face ring assembly is provided with a toggle groove extending along its axial direction, the toggle member is slidably connected in the toggle groove and partially extends into the light emission cavity, and when the toggle member moves along the toggle groove, it drives the heat dissipation assembly to rotate relative to the face ring assembly.

[0007] Furthermore, the heat dissipation assembly includes a first-diameter heat dissipation component and a second-diameter heat dissipation component. The first-diameter heat dissipation component is rotatably connected to the face ring assembly and rotatably connected to the actuating component. The second-diameter heat dissipation component is movable relative to the first-diameter heat dissipation component in the radial direction of the heat dissipation assembly. The light source component is disposed on the second-diameter heat dissipation component.

[0008] Furthermore, one of the first-diameter heat sink and the second-diameter heat sink is provided with a limiting hole, and the other of the two is provided with a limiting ball that is inserted and engaged with the limiting hole. There are several limiting holes, which are spaced apart in the moving direction of the second-diameter heat sink. When the second-diameter heat sink moves relative to the first-diameter heat sink, the limiting ball can move from one limiting hole into an adjacent limiting hole.

[0009] Furthermore, one of the first-diameter heat sink and the second-diameter heat sink is provided with a guide groove, and the other of the two is provided with a guide block that slides with the guide groove, and the guide groove extends in the moving direction of the second-diameter heat sink.

[0010] Furthermore, the face ring assembly includes an inner ring and an outer ring, the outer ring being disposed outside the inner ring, the inner ring having the light-emitting cavity and an exposed hole communicating with the light-emitting cavity, an outer abutment block partially extending out of the exposed hole being rotatably connected to the inner ring, and an inner abutment block for pushing the outer abutment block being provided on the inner side of the outer ring, the inner abutment block being able to drive the outer abutment block to swing from one end of the exposed hole to the other end of the exposed hole when the outer ring rotates relative to the inner ring.

[0011] Furthermore, the face ring assembly and the heat dissipation assembly together form a clearance hole, the clearance hole and the toggle member are arranged opposite each other in the radial direction of the face ring assembly, and a light-shielding member is provided in the light-emitting cavity, the light-shielding member can move relative to the face ring assembly to open and close the clearance hole.

[0012] Furthermore, the face ring assembly is provided with a light-shielding groove extending along its axial direction, the light-shielding member is slidably connected in the light-shielding groove and partially extends into the light-emitting cavity, and the light-shielding member opens and closes the clearance hole when it moves along the light-shielding groove.

[0013] The advantage of this technical solution lies in that, by configuring the face ring assembly to be rotatably connected to the heat dissipation assembly, and by placing a toggle component within the light emission cavity that can move up and down relative to the face ring assembly and is rotatably connected to the heat dissipation assembly, the up-and-down movement of the toggle component relative to the face ring assembly causes the heat dissipation assembly to swing left and right, thereby adjusting the light emission angle of the light source. Since the toggle component is located within the light emission cavity, when it is necessary to adjust the light emission angle of the light source, one only needs to insert a hand into the light emission cavity and push the toggle component up and down; there is no need to disassemble the entire downlight, making operation simple and convenient.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Figures 1-11 As shown, the front-mounted adjustable downlight includes a face ring assembly 1, a heat dissipation assembly 2, and a light source 3. The face ring assembly 1 is rotatably connected to the heat dissipation assembly 2 and has a light emission cavity 101. The light source 3 is disposed on the heat dissipation assembly 2 and partially housed within the light emission cavity 101. A toggle member 4, rotatably connected to the heat dissipation assembly 2, is provided within the light emission cavity 101. The toggle member 4 can move relative to the face ring assembly 1, causing the heat dissipation assembly 2 to rotate relative to the face ring assembly 1. The axial direction of the face ring assembly 1 is defined as the up-down direction. The toggle member 4 can move up and down relative to the face ring assembly 1. When the toggle member 4 moves up and down relative to the face ring assembly 1, it causes the heat dissipation assembly 2 to swing left and right relative to the face ring assembly 1, thereby adjusting the light emission angle of the light source 3.

[0029] This embodiment provides a front-mounted adjustable downlight to solve the problem that existing downlights have their adjustment structure located at the connection between the face ring component and the heat sink component. This necessitates removing the entire downlight from the ceiling to adjust the light emission angle of the light source, which is extremely inconvenient. The solution is achieved by configuring the face ring component 1 to be rotatably connected to the heat sink component 2, and by placing a toggle member 4 within the light emission cavity 101 that can move up and down relative to the face ring component 1 and is rotatably connected to the heat sink component 2. Therefore, when the toggle member 4 moves up and down relative to the face ring component 1, it causes the heat sink component 2 to swing left and right, thereby adjusting the light emission angle of the light source component 3. Since the toggle member 4 is located within the light emission cavity 101, adjusting the light emission angle of the light source component 3 only requires inserting a hand into the light emission cavity 101 to push the toggle member 4 up and down, without needing to remove the entire downlight, making the operation simple and convenient.

[0030] In this embodiment of the invention, the wall of the light-emitting cavity 101 is provided with several markings (not shown in the figure) on one side of the actuating member 4. These markings are spaced apart in the moving direction of the actuating member 4. The markings are used to indicate the angle of rotation of the heat dissipation assembly 2 relative to the face ring assembly 1 when the actuating member 4 moves to that position. The markings can be, but are not limited to, 10°, 20°, 30°, etc. The above arrangement facilitates intuitive operation and precise adjustment by the user.

[0031] In this embodiment of the invention, the face ring assembly 1 is provided with a toggle groove 102 extending along its axial direction. The toggle member 4 is slidably connected within the toggle groove 102 and partially extends into the light emission cavity 101. When the toggle member 4 moves along the toggle groove 102, it drives the heat dissipation assembly 2 to rotate relative to the face ring assembly 1. The above arrangement, by configuring the toggle groove 102 on the face ring assembly 1 to slide with the toggle member 4, ensures stable assembly and smooth movement of the toggle member 4 and the face ring assembly 1.

[0032] In this embodiment of the present invention, the heat dissipation assembly 2 includes a first-radius heat dissipation component 201 and a second-radius heat dissipation component 202. The first-radius heat dissipation component 201 is rotatably connected to the face ring assembly 1 and rotatably connected to the actuating component 4. The second-radius heat dissipation component 202 can move relative to the first-radius heat dissipation component 201 in the radial direction of the heat dissipation assembly 2. The light source component 3 is disposed on the second-radius heat dissipation component 202. By configuring the heat dissipation assembly 2 with the first-radius heat dissipation component 201 and the second-radius heat dissipation component 202 that can move relative to each other in the radial direction, the position of the light source component 3 can be adjusted by moving the second-radius heat dissipation component 202, thus preventing the light from the light source component 3 from hitting the cavity wall of the light emission cavity 101, and giving the light source component 3 a good light emission effect.

[0033] In this embodiment of the invention, the second-diameter heat sink 202 is provided with a limiting hole 203, and the first-diameter heat sink 201 is provided with a limiting ball 204 that engages with the limiting hole 203. There are several limiting holes 203, spaced apart in the moving direction of the second-diameter heat sink 202. When the second-diameter heat sink 202 moves relative to the first-diameter heat sink 201, the limiting ball 204 can move from one limiting hole 203 into an adjacent limiting hole 203. This arrangement, by configuring the limiting hole 203 on the second-diameter heat sink 202 and the limiting ball 204 on the first-diameter heat sink 201, ensures a stable connection between the second-diameter heat sink 202 and the first-diameter heat sink 201 after the second-diameter heat sink 202 has moved into position.

[0034] In other embodiments, the limiting hole 203 is disposed on the first diameter heat sink 201, and the limiting ball 204 is disposed on the second diameter heat sink 202.

[0035] In this embodiment of the invention, the second-diameter heat sink 202 is provided with a guide groove 205 extending in its moving direction, and the first-diameter heat sink 201 is provided with a guide block 206 that slides with the guide groove 205. This arrangement, by configuring the guide groove 205 on the second-diameter heat sink 202 and the guide block 206 on the first-diameter heat sink 201, ensures stable and smooth movement of the second-diameter heat sink 202.

[0036] In other embodiments, the guide groove 205 is disposed on the first diameter heat sink 201, and the guide block 206 is disposed on the second diameter heat sink 202.

[0037] In this embodiment of the utility model, the second diameter heat sink 202 and the first diameter heat sink 201 abut against each other vertically, and the limiting hole 203 is provided on the side where the second diameter heat sink 202 and the first diameter heat sink 201 abut against each other and is located on the side of the guide groove 205.

[0038] In this embodiment of the present invention, the face ring assembly 1 includes an inner ring 103 and an outer ring 104. The outer ring 104 is disposed around the inner ring 103. The inner ring 103 is rotatably connected to a heat sink 201. The inner ring 103 has a light-emitting cavity 101 and an exposed hole 105 communicating with the light-emitting cavity 101. An outer abutment 106 is rotatably connected to the inner ring 103, extending out of the exposed hole 105. An inner abutment 107 is provided on the inner side of the outer ring 104 for pushing the outer abutment 106. When the outer ring 104 rotates relative to the inner ring 103, the inner abutment 107 can drive the outer abutment 106 to swing from one end of the exposed hole 105 to the other end of the exposed hole 105. In this design, the inner abutment block 107 drives the outer abutment block 106 to swing from one end of the exposed hole 105 to the other end. The inner abutment block 107 and the outer abutment block 106 then abut against each other, restricting the relative rotation of the inner ring 103 and the outer ring 104. At this time, the outer ring 104 can only rotate in the opposite direction. When the outer ring 104 rotates in the opposite direction, causing the inner abutment block 107 to abut against the outer abutment block 106 again, the inner abutment block 107 again drives the outer abutment block 106 to swing from one end of the exposed hole 105 to the other end. Because the inner abutment block 107 can drive the outer abutment block 106 to swing from one end of the exposed hole 105 to the other end when the outer ring 104 rotates relative to the inner ring 103, the outer ring 104 can rotate 360° or slightly more than 360° relative to the inner ring 103. This provides a wide range of rotation and excellent adjustment. Simultaneously, it prevents the outer ring 104 from continuously rotating in the same direction, thus avoiding wire entanglement.

[0039] In this embodiment of the invention, the face ring assembly 1 and the heat dissipation assembly 2 together form a clearance hole 5. The clearance hole 5 and the actuating member 4 are arranged opposite each other in the radial direction of the face ring assembly 1. A light-shielding member 6 is provided in the light-emitting cavity 101. The light-shielding member 6 can move relative to the face ring assembly 1 to open and close the clearance hole 5. The clearance hole 5 is configured to prevent interference and collision between the heat dissipation assembly 2 and the face ring assembly 1 when the assembly rotates, while the light-shielding member 6 is configured to prevent light leakage.

[0040] In this embodiment of the invention, the face ring assembly 1 is provided with a light-shielding groove 108 extending along its axial direction. The light-shielding member 6 is slidably connected within the light-shielding groove 108 and partially extends into the light-emitting cavity 101. When the light-shielding member 6 moves along the light-shielding groove 108, it opens and closes the clearance hole 5. The above arrangement, by configuring the light-shielding groove 108 on the face ring assembly 1 to slide with the light-shielding member 6, ensures a stable connection and smooth movement between the light-shielding member 6 and the face ring assembly 1.
