Description

Technical Field

[0001] The present invention relates to the technical field of lighting, and in particular to a downlight with adjustable irradiation angle and an assembly method thereof. Background Art

[0002] A downlight is a common lighting tool. A traditional downlight has a screw socket lamp holder, and it can usually be directly installed with an incandescent lamp or an energy-saving lamp. Most downlights are installed in the ceiling and illuminate in a downward light-emitting manner. Its advantages are as follows: it can maintain the overall unity and perfection of architectural decoration, and will not damage the perfect unity of the ceiling art due to the placement of the lamp. Moreover, the downlight does not occupy space and can increase the soft atmosphere of the space. However, the irradiation angle of a traditional downlight is usually difficult to adjust after installation, while in some occasions, it is usually necessary to adjust the irradiation angle of the lamp to meet the scene requirements.

[0003] In the prior art, there are also some downlights that can adjust the angle. For example, the patent document with the publication number CN215446209U discloses a downlight with a rotary angle adjustment function, which includes a face frame, an inner frame and a heat dissipation cover. The bottom end of the inner frame is sleeved in the face frame and pivotally connected to the side walls of the face frame on both sides. An adjustment groove is provided on the outer wall of the top end of the inner frame. The adjustment groove includes a horizontal section arranged along the circumferential direction and a vertical section arranged along the axial direction. The top end of the vertical section is open. The heat dissipation cover is sleeved outside the inner frame and its bottom end abuts against the top surface of the face frame. An adjustment block matching the adjustment groove is provided on the inner wall of the heat dissipation cover. The distance from the adjustment block to the bottom surface of the heat dissipation cover is greater than the distance from the adjustment groove to the top surface of the face frame. When it works, in the initial state, the adjustment block of the heat dissipation cover is located in the vertical section of the adjustment groove, and the heat dissipation cover is stuck by the clamping block of the inner frame. At this time, the inner frame is in a horizontal state; rotating the heat dissipation cover makes the adjustment block enter the horizontal section of the adjustment groove, and the adjustment block will lift one side of the inner frame to make it tilt. After the adjustment block enters the end of the horizontal section, the clamping block is engaged with the clamping groove, thereby locking the angle of the inner frame.

[0004] However, the defect of the above-mentioned downlight with a rotary angle adjustment function is that since the angle of the inner frame is locked after the clamping block is engaged with the clamping groove, the downlight can usually only adjust one angle and is difficult to adapt to different occasions. At the same time, there is a situation where the luminous effect is poor after the irradiation angle of the above-mentioned downlight is adjusted. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems in the above technologies to some extent. For this reason, an object of the present invention is to provide a downlight with adjustable irradiation angle, which is convenient to adjust the irradiation angle and can adjust multiple irradiation angles.

[0006] A second object of the present invention is to provide an assembly method of a downlight, which is convenient to assemble the downlight, convenient to adjust the irradiation angle after assembly, and can adjust multiple irradiation angles.

[0007] To achieve the above-mentioned object, an embodiment of the present invention provides a downlight with adjustable illumination angle, comprising a main body and a reflector cup;

[0008] A light-emitting component is provided in the body, and a first adjusting member is provided on the body;

[0009] A reflective surface for reflecting light emitted by the light-emitting component is provided in the reflective cup. The reflective cup can be rotatably mounted on the main body at multiple angles. A notch is formed on the side of the reflective cup for rotation of the reflective cup. A second adjustment member that cooperates with the first adjustment member is provided on the reflective cup. A limiting structure for limiting the rotation of the reflective cup is provided between the second adjustment member and the first adjustment member. The limiting structure limits the reflective cup to one of the multiple angles.

[0010] According to an embodiment of the present invention, a downlight with adjustable illumination angle, after installation, can rotate the reflector cup to multiple angles, thereby adjusting the angle of the reflective surface within the reflector cup, thereby changing the direction of the light and achieving a better reflective effect. To adjust the illumination angle, force is applied to the reflector cup to rotate it to one of the multiple angles. The force is then released, and the reflector cup stops rotating. At this time, a retaining structure constrains the reflector cup to the specified angle, thereby positioning the reflector cup at that angle, effectively preventing the reflector cup from rotating without external force, thereby maintaining the direction of the light. To adjust the angle again, force is applied to the reflector cup to rotate it to another of the multiple angles. The force is then released, and the reflector cup stops rotating. The retaining structure constrains the reflector cup to the specified angle, thereby completing the angle adjustment. After the adjustment is completed, the reflector cup is again prevented from rotating without external force, maintaining the direction of the light. Therefore, the present invention facilitates adjustment of the illumination angle and can adjust multiple illumination angles.

[0011] In addition, the downlight with adjustable illumination angle according to the above embodiment of the present invention may also have the following additional technical features:

[0012] Furthermore, a first limiting groove is provided on the first adjusting member, and a first limiting block is provided on the main body, and the first limiting block is snapped into the first limiting groove and fixed.

[0015] Furthermore, the tooth patterns are arranged in an arc shape.

[0016] Furthermore, a rotation hole is provided on the first limit block, a first perforation is provided on the first adjustment member, a second perforation is provided on the second adjustment member, and a third perforation is provided on the reflective cup; the downlight also includes a connecting member, which passes through the third perforation, the second perforation, the first perforation and the rotation hole in sequence to rotatably set the reflective cup on the main body.

[0017] Furthermore, a second limiting groove is provided on the reflective cup, and the second adjusting member is a second limiting block, which is fixed by being snapped into the second limiting groove.

[0018] Furthermore, the second limiting groove is a second dovetail groove, and the second limiting block is configured as a second dovetail block that cooperates with the second dovetail groove.

[0019] Furthermore, the second adjusting member protrudes to form an elastic rod, and the end of the elastic rod forms the elastic tooth block.

[0020] Furthermore, there are at least two tooth grooves, and when the elastic tooth block is engaged from one tooth groove into another adjacent tooth groove, the reflective cup rotates at least 5°.

[0021] Furthermore, the number of tooth grooves is six, and when the elastic tooth block is engaged from one tooth groove to another adjacent tooth groove, the reflective cup rotates 5 degrees.

[0022] Furthermore, a fixing hole is provided on the first limit block, and a fourth through-hole is provided on the first adjusting member; the downlight also includes a connecting member, which passes through the third through-hole, the second through-hole, the fourth through-hole and the fixing hole in sequence to set the reflective cup on the main body, and the side of the elastic tooth block abuts against the side of the tooth pattern to prevent the reflective cup from rotating.

[0023] Furthermore, the reflecting surface is curved, and the height of the reflecting surface gradually increases from a direction close to the clearance notch to a direction away from the clearance notch.

[0024] To achieve the above-mentioned object, a second aspect of an embodiment of the present invention provides a method for assembling a downlight, comprising the following steps:

[0025] Step 1: Align the first limiting groove of the first adjusting member with the first limiting block of the main body, and insert the first limiting groove along the first limiting block;

[0026] Step 2: Align the second limiting block of the second adjusting member with the second limiting groove of the reflective cup, and insert the second limiting block along the second limiting groove;

[0027] Step 3: Place the reflector on the main body so that the third through-hole on the reflector, the second through-hole on the second adjusting member, the first through-hole on the first adjusting member, and the rotating hole on the main body are in a straight line;

[0028] Step 4: Use a connecting piece to pass through the third through hole, the second through hole, the first through hole and the rotating hole in sequence so that the reflective cup can be rotatably mounted on the main body.

At the same time, after assembling, the elastic tooth block is snapped into a tooth groove, which can apply force to the reflector cup, causing the elastic tooth block to deform, so that the elastic tooth block snaps from one tooth groove into another tooth groove. After rotating to a suitable angle, stop applying force, and the elastic tooth block is snapped into this tooth groove, thereby positioning the reflector cup and effectively preventing the reflector cup from rotating without external force.

[0044] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0045] As Figures 1 to 8 shown, a downlight with an adjustable irradiation angle according to an embodiment of the present invention includes a main body 1 and a reflector cup 2; a light-emitting component is arranged in the main body 1. Among them, the light-emitting component can be a lamp bead capable of emitting light, and the lamp bead can cooperate with a lens to improve the irradiation effect. A first adjusting member 3 is arranged on the main body 1. A reflecting surface for reflecting the light emitted by the light-emitting component is arranged in the reflector cup 2. The reflector cup 2 can be rotatably arranged on the main body 1 from multiple angles. A relief notch 21 for the rotation of the reflector cup 2 is formed on the side of the reflector cup 2. A second adjusting member 4 cooperating with the first adjusting member 3 is arranged on the reflector cup 2. A limiting structure 5 for restricting the rotation of the reflector cup 2 is arranged between the second adjusting member 4 and the first adjusting member 3. The limiting structure 5 restricts the reflector cup 2 to one of multiple angles.

[0046] After installing the downlight, the reflector cup 2 can be rotated from multiple angles, so as to adjust the angle of the reflecting surface inside the reflector cup 2, thereby changing the light direction, and the reflecting effect of the reflecting surface is good. When it is necessary to adjust the light emitting angle, apply force to the reflector cup 2 to rotate the reflector cup 2 to one of multiple angles, and then stop applying force. The reflector cup 2 stops rotating. At this time, the limiting structure 5 restricts the reflector cup 2 to this angle, thereby positioning the reflector cup 2 at this angle, effectively preventing the reflector cup 2 from rotating under the action of non-external force, so that the light direction will not change. When it is necessary to adjust the angle, apply force to the reflector cup 2 again to rotate the reflector cup 2 to another angle among multiple angles, and then stop applying force and the reflector cup 2 stops rotating. At this time, the limiting structure 5 restricts the reflector cup 2 to this other angle, thereby completing the angle adjustment, and preventing the reflector cup 2 from rotating under the action of non-external force again after the adjustment is completed, and the light direction will not change. Therefore, the present invention is convenient for adjusting the irradiation angle, can adjust multiple irradiation angles, and after the adjustment, the limiting structure 5 of the reflector cup 2 limits the reflector cup 2, making the reflector cup 2 not easy to rotate.

[0047] Optionally, a first limiting groove 31 is provided on the first adjusting member 3, and a first limiting block 11 is provided on the body 1. The first limiting block 11 is fixed by being snapped into the first limiting groove 31. Among them, the first limiting groove 31 can be a first dovetail groove, and the first limiting block 11 can be provided with a first dovetail block that cooperates with the first dovetail groove. During assembly, directly align the first limiting block 11 of the body 1 with the first limiting groove 31 of the first adjusting member 3, so that the first dovetail block is inserted into the first dovetail groove, and the first adjusting member 3 can be assembled on the body 1. The assembly efficiency is fast and the assembly is extremely convenient. At the same time, the cooperation between the first dovetail block and the first dovetail groove can prevent the first adjusting member 3 from shaking, and the stability is high.

[0048] Optionally, a tooth pattern 51 is formed on the first adjusting member 3. The tooth pattern 51 has a plurality of saw teeth 511, and a tooth groove 512 is formed between adjacent saw teeth 511. An elastic tooth block 52 that is snapped into the tooth groove 512 is provided on the second adjusting member 4. That is to say, the limiting structure 5 is a mutually cooperating structure of the tooth groove 512 and the elastic tooth block 52. When it is necessary to adjust the light angle, apply force to the reflector cup 2 to make the elastic tooth block 52 snap from one tooth groove 512 into another tooth groove 512, and then stop applying force. Another tooth groove 512 restricts the rotation of the elastic tooth block 52, thereby adjusting the light to another angle. When it is necessary to adjust the light angle in the present invention, only apply force to the reflector cup 2 to make the elastic tooth block 52 snap from one tooth groove 512 into another tooth groove 512. After adjusting to a suitable angle, the tooth groove 512 restricts the rotation of the elastic tooth block 52, so that the reflector cup 2 of the downlight will not rotate under non-external force. Therefore, the present invention is extremely convenient for switching the light angle, and the reflector cup 2 will not rotate after switching.

[0049] In this example, the tooth pattern 51 is arranged in an arc. Among them, the center of the circle corresponding to the arc coincides with the rotation center of the second adjusting member 4, so that the elastic tooth block 52 can effectively engage in the tooth groove 512. That is, when rotating, the elastic tooth block 52 can easily engage from one tooth groove 512 into another tooth groove 512, and the elastic tooth block 52 will not jam.

[0050] Among them, the longitudinal section of the elastic tooth block 52 is triangular, and the tooth groove 512 is V-shaped, and the elastic tooth block 52 just fits into the V-shaped tooth groove. Since the V-shaped tooth groove has a first inclined surface and a second inclined surface opposite to the first inclined surface, it is convenient for the elastic tooth block 52 to slide out along the first inclined surface or the second inclined surface, making it extremely convenient when the irradiation angle needs to be rotated.

[0051] In some examples, a rotation hole 111 is provided on the first limiting block 11, a first through hole 32 is provided on the first adjusting member 3, a second through hole 41 is provided on the second adjusting member 4, and a third through hole 22 is provided on the reflector 2. The downlight further includes a connecting member, and the connecting member sequentially passes through the third through hole 22, the second through hole 41, the first through hole 32 and the rotation hole 111 to rotatably arrange the reflector 2 on the main body 1. The connecting member can be a bolt or a rotating shaft. After the bolt or the rotating shaft passes through the third through hole 22, the second through hole 41, the first through hole 32 and the rotation hole 111, the reflector 2 can be rotatably arranged on the main body 1 along the rotating member. The tooth groove 512 and the elastic tooth block 52 in the limiting structure 5 limit the rotation of the reflector 2, so that the reflector 2 will not rotate without external force. When the light angle needs to be adjusted, a force is applied to the reflector 2 to make the elastic tooth block 52 engage from one tooth groove 512 into another tooth groove 512, making a clicking sound. After the force is stopped, another tooth groove 512 restricts the rotation of the reflector 2.

[0052] As an example, a second limiting groove 23 is provided on the reflector 2, and a second limiting block 42 is provided on the second adjusting member 4. The second limiting block 42 is engaged in the second limiting groove 23 for fixation. The second limiting groove 23 in this example is a second dovetail groove, and the second limiting block 42 is arranged as a second dovetail block that cooperates with the second dovetail groove. During assembly, directly align the second limiting block 42 of the second adjusting member 4 with the second limiting groove 23 of the reflector 2, so that the second dovetail block can be inserted into the second dovetail groove to complete the assembly of the second adjusting member 4 on the reflector 2. The assembly efficiency is high and the assembly is extremely convenient. At the same time, the cooperation between the second dovetail block and the second dovetail groove can prevent the second adjusting member 4 from shaking, and the stability is high.

[0053] As an example, two second dovetail grooves are provided on the reflector cup 2, one of the second dovetail grooves is located on one side of the reflector cup 2, and the other second dovetail groove is located on the other side of the reflector cup 2. The second adjusting members 4 are provided in two, and the two second adjusting members 4 are symmetrically arranged. The second dovetail block of one of the second adjusting members 4 is inserted into one second dovetail groove, and the second dovetail block of the other second adjusting member 4 is inserted into the other second dovetail groove. Two first dovetail grooves are provided on the body 1, one of the first dovetail grooves is located on one side of the body 1, and the other first dovetail groove is located on the other side of the body 1. The first adjusting members 3 are provided in two, and the two first adjusting members 3 are symmetrically arranged. The first dovetail block of one of the first adjusting members 3 is inserted into one first dovetail groove, and the first dovetail block of the other first adjusting member 3 is inserted into the other first dovetail groove.

[0054] After the two second adjusting members 4 are assembled on both sides of the reflector cup 2 and the two first adjusting members 3 are assembled on both sides of the body 1, the reflector cup 2 is mounted on the body 1. Then, bolts or a rotating shaft are sequentially passed through the third through hole 22, the second through hole 41, the first through hole 32, and the rotating hole 111, so that the reflector cup 2 can be rotatably arranged on the body 1 along the rotating member.

[0055] In some examples, the second adjusting member 4 protrudes to form an elastic rod 43, and the end of the elastic rod 43 forms the elastic tooth block 52. When the elastic tooth block 52 is snapped from one tooth groove 512 into another tooth groove 512, the elastic rod 43 deforms, thereby facilitating the snapping of the elastic tooth block 52 into the tooth groove 512.

[0056] Among them, the tooth grooves 512 can be provided in at least two. When the elastic tooth block 52 is snapped from one tooth groove 512 into another adjacent tooth groove 512, the reflector cup 2 rotates by at least 5°. In this example, as Figure 6 shown, the tooth grooves 512 are provided in six. When the elastic tooth block 52 is snapped from one tooth groove 512 into another adjacent tooth groove 512, the reflector cup 2 rotates by 5°. That is to say, the maximum rotation angle of the reflector cup 2 is 25°, that is, it is divided into six grades, which are 0°, 5°, 10°, 15°, 20°, and 25° in sequence, and the corresponding angle can be selected according to the actual scenario. Of course, the number of the tooth grooves 512 can be set to other numbers according to specific situations, and there is no limit here.

[0057] When the tooth grooves 512 are provided in six, as Figure 6As shown in the figure, from right to left are the first tooth groove, the second tooth groove, the third tooth groove, the fourth tooth groove, the fifth tooth groove and the sixth tooth groove. When the elastic tooth block 52 is located in the first tooth groove, the axial center line of the reflector cup 2 is parallel to the axial center line of the body 1. When the elastic tooth block 52 moves from the first tooth groove to the second tooth groove, the included angle between the axial center line of the reflector cup 2 and the axial center line of the body 1 is 5°. When the elastic tooth block 52 moves from the second tooth groove to the third tooth groove, the included angle between the axial center line of the reflector cup 2 and the axial center line of the body 1 is 10°. When the elastic tooth block 52 moves from the third tooth groove to the fourth tooth groove, the included angle between the axial center line of the reflector cup 2 and the axial center line of the body 1 is 15°. When the elastic tooth block 52 moves from the fourth tooth groove to the fifth tooth groove, the included angle between the axial center line of the reflector cup 2 and the axial center line of the body 1 is 20°. When the elastic tooth block 52 moves from the fifth tooth groove to the sixth tooth groove, the included angle between the axial center line of the reflector cup 2 and the axial center line of the body 1 is 25°.

[0058] As an example, the reflecting surface is curved, and the height of the reflecting surface gradually increases from the direction close to the relief notch 21 to the direction away from the relief notch 21. That is to say, the height of the reflecting surface at the position close to the relief notch 21 is less than the height of the reflecting surface at the position away from the relief notch 21, so as to adapt to the reflector cup 2 with the relief notch 21. At the same time, after the reflector cup 2 rotates, the reflecting surface rotates accordingly, so that the light emitted by the light-emitting component can be effectively reflected by the reflecting surface, and the reflection effect is good. In this example, a heat dissipation housing 12 is provided on the body 1 to improve the heat dissipation performance.

[0059] In some examples, a fixing hole 112 is provided on the first limiting block 11, a fourth through hole 33 is provided on the first adjusting member 3, and the connecting member sequentially passes through the third through hole 22, the second through hole 41, the fourth through hole 33 and the fixing hole 112 to set the reflector cup 2 on the body 1. The side of the elastic tooth block 52 abuts against the side of the tooth pattern 51 to prevent the reflector cup 2 from rotating. That is to say, in this example, the fixing hole 112 or the rotating hole 111 can be selected according to different needs. When the rotating hole 111 is selected, the reflector cup 2 can rotate, and the limiting structure 5 restricts its rotation, and the reflector cup 2 can be driven to rotate only under the action of an external force. When the fixing hole 112 is selected, at this time, the axial center line of the body 1 is consistent with the axial center line of the reflector cup 2, the side of the elastic tooth block 52 abuts against the side of the tooth pattern 51, and the reflector cup 2 does not rotate under the action of an external force, so that the downlight has multiple functions.

[0060] The embodiment of the present invention also provides an assembly method for a downlight, including the following steps:

[0061] Step 1: Align the first limiting groove 31 of the first adjusting member 3 with the first limiting block 11 of the main body 1, and insert the first limiting groove 31 along the first limiting block 11, thus completing the assembly of the first adjusting member 3 on the main body 1. The assembly efficiency is high and the assembly is simple. At the same time, the cooperation between the first limiting groove 31 and the first limiting block 11 prevents the first adjusting member 3 from shaking and improves stability.

[0062] Step 2: Align the second limiting block 42 of the second adjusting member 4 with the second limiting groove 23 of the reflector cup 2, and insert the second limiting block 42 along the second limiting groove 23, thus completing the assembly of the second adjusting member 4 on the reflector cup 2. The assembly efficiency is high and the assembly is simple. At the same time, the cooperation between the second limiting groove 23 and the second limiting block 42 prevents the second adjusting member 4 from shaking and improves stability.

[0063] Step 3: Place the reflector cup 2 on the main body 1 so that the third through hole 22 on the reflector cup 2, the second through hole 41 on the second adjusting member 4, the first through hole 32 on the first adjusting member 3, and the rotation hole 111 on the main body 1 are on the same straight line.

[0064] Step 4: Use a connecting member to sequentially pass through the third through hole 22, the second through hole 41, the first through hole 32, and the rotation hole 111 to rotatably arrange the reflector cup 2 on the main body 1. Among them, the connecting member can be a bolt or a rotating shaft.

[0065] When assembling the downlight, first align the first limiting groove 31 of the first adjusting member 3 with the first limiting block 11 of the main body 1, and insert the first limiting groove 31 along the first limiting block 11. Align the second limiting block 42 of the second adjusting member 4 with the second limiting groove 23 of the reflector cup 2, and insert the second limiting block 42 along the second limiting groove 23. Then place the reflector cup 2 on the main body 1 so that the third through hole 22 on the reflector cup 2, the second through hole 41 on the second adjusting member 4, the first through hole 32 on the first adjusting member 3, and the rotation hole 111 on the main body 1 are on the same straight line. Finally, use a connecting member to sequentially pass through the third through hole 22, the second through hole 41, the first through hole 32, and the rotation hole 111 to rotatably arrange the reflector cup 2 on the main body 1. At this time, the elastic tooth block 52 snaps into a tooth groove 512. Therefore, the downlight assembly method of the present invention is simple, the assembly efficiency is high. At the same time, after assembly, the elastic tooth block 52 snaps into a tooth groove 512, which can apply force to the reflector cup 2, causing the elastic tooth block 52 to deform, so that the elastic tooth block 52 snaps from one tooth groove 512 into another tooth groove 512. After rotating to a suitable angle, stop applying force, and the elastic tooth block 52 snaps into this tooth groove 512, thereby positioning the reflector cup 2 and effectively preventing the reflector cup 2 from rotating without external force.

[0066] Optionally, the first limiting groove 31 may be a first dovetail groove, and the first limiting block 11 may be provided with a first dovetail block that cooperates with the first dovetail groove. During assembly, directly align the first limiting block 11 of the body 1 with the first limiting groove 31 of the first adjusting member 3, so that the first dovetail block is inserted into the first dovetail groove, and the first adjusting member 3 can be assembled on the body 1. The assembly efficiency is high and the assembly is extremely convenient. At the same time, the cooperation between the first dovetail block and the first dovetail groove can prevent the first adjusting member 3 from shaking, and the stability is high. The second limiting groove 23 is a second dovetail groove, and the second limiting block 42 is provided as a second dovetail block that cooperates with the second dovetail groove. During assembly, directly align the second limiting block 42 of the second adjusting member 4 with the second limiting groove 23 of the reflector 2, so that the second dovetail block is inserted into the second dovetail groove, and the second adjusting member 4 can be assembled on the reflector 2. The assembly efficiency is high and the assembly is extremely convenient. At the same time, the cooperation between the second dovetail block and the second dovetail groove can prevent the second adjusting member 4 from shaking, and the stability is high.

[0067] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
