Description

Technical Field

[0001] This utility model belongs to the technical field of lighting devices, specifically relating to an installation structure and a lamp. Background Technology

[0002] Downlights or spotlights, which use direct (or angled) lighting, generally consist of a lamp body, a light source, and optical components. The optical components further include a lens, a lens holder, and a face ring. The face ring, also known as an anti-glare ring, is used to adjust the light output and reduce glare.

[0003] Existing methods for fixing anti-glare rings generally include the following: (1) Clip fixing: a slot is set in the anti-glare ring, the lamp body is made of plastic and has protrusions molded on the inside, the protrusions are engaged and connected to the slot, which can meet the requirement of screwless structure. However, this clip structure only relies on clip locking and has no anti-locking pressing structure, which has the problem of insufficient locking strength and the risk of anti-glare ring slippage. (2) Screw fixing: screw holes and screws are used for connection. This installation structure has good stability, but the screws are exposed on the outside of the lamp body, which will affect the overall appearance and does not conform to the current trend of screwless lamps. In addition, the above structures are all based on the anti-glare ring being fixed and installed, and then the lens is pressed by the anti-glare ring to lock it. (3) Non-removable ultrasonic welding or high-frequency welding: these installation structures require the use of external welding / welding equipment, which is not convenient for the installation of anti-glare rings.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0052] Example 1

[0053] refer to Figures 1-5 This embodiment provides a mounting structure 100 for mounting optical components of lamps such as downlights, spotlights, or ceiling lights. The mounting structure 100 includes a bracket 1 and a face ring 2, the face ring 2 being non-removably mounted on the bracket 1. The bracket 1 is an injection-molded plastic part, including a first mounting portion 11, a second mounting portion 12, and a bracket body 13. The first mounting portion 11 and the second mounting portion 12 are respectively disposed at both ends of the bracket body 13, with the second mounting portion 12 fixedly connected to the lamp body. The first mounting portion 11 includes a first ring body 111 and a second ring body 112. The bracket body 13 has a bowl-shaped structure, with the first ring body 111 and the second ring body 112 disposed at the light-emitting end of the bracket body 13, and the second ring body 112 located outside the first ring body 111. The second ring body 112 is provided with a slot 113, and the first ring body 111 is provided with a limiting member 114, the limiting member 114 extending arcuately toward the slot 113.

[0054] The face ring 2 has an anti-glare function and can adjust the emitted light. The face ring 2 includes a light-emitting part 21 and a locking part 22 for connecting with the bracket 1. The locking part 22 is used to connect with the bracket 1. The locking part 22 includes a spring arm 221 and a protrusion 222, with the protrusion 222 located on the outer side of the spring arm 221. The locking part 22 is engaged in the slot 113, at which time the protrusion 222 abuts against the second ring body 112, and the limiting member 114 abuts against the inner sidewall of the spring arm 221. Through the snap-fit ​​connection between the locking part 22 and the slot 113, and the elastic abutment of the limiting member 114 against the spring arm, the face ring 2 is locked to the bracket 1. This locking connection structure is non-removable, so the face ring 2 will not easily fall off the bracket 1, greatly reducing the risk of the face ring falling off.

[0055] In some embodiments, the limiting member 114 extends obliquely downward in an arc shape from the top of the first ring body 111 toward the slot 113, and the limiting member 114 is provided with a limiting arc surface 115; correspondingly, the spring arm 221 is provided with a first stop surface 2211 on its inner sidewall. When the limiting member 114 and the spring arm 221 are in an interference fit, the limiting arc surface 115 abuts against the first stop surface 2211 in the radial direction X.

[0056] In some embodiments, the bracket 1 is provided with three arc-shaped extending limiting members 114, and correspondingly, three elastic arms 221 are also provided on the face ring 2. The three limiting members 114 and the three elastic arms 221 cooperate with each other to form a stable triangular connection structure. The limiting members 114 are resilient arc-shaped elastic rib structures, and will not break due to interference fit when the limiting members 114 abut against the elastic arms 221.

[0057] Furthermore, the second ring body 112 is provided with an outer perimeter 116 extending outward, the perimeter 116 including an upper edge 1161 and a lower edge 1162. In the spring arm 221, the protrusion 222 includes a guide surface 2221 and a second stop surface 2222. During the installation of the face ring 2 to the bracket 1, the protrusion 222 is engaged in the slot 113 through the guide surface 2221, and then the lower edge 1162 abuts against the second stop surface 2222 in the height direction Y.

[0058] After the face ring 2 is snapped onto the bracket 1, in the radial direction X, the limiting arc surface 115 abuts against the first stop surface 2211 of the spring arm 221; in the height direction Y, the lower edge 1162 of the circumference 116 abuts against the second stop surface 2222 of the spring arm 221. In this way, through the engaging snap connection between the locking part 22 and the first ring body 111 and the second ring body 1112, a "locked" installation structure is formed, and the face ring 2 is locked in the bracket 1 from all directions, achieving a non-removable fixed connection between the face ring 2 and the bracket 1, preventing the face ring 2 from falling out of the bracket 1.

[0059] Reference Figure 3 and Figure 4The rim 116 protrudes outward and also includes an inner rim wall 1163 disposed between the upper edge 1161 and the lower edge 1162. In the radial direction X, the distance between the upper edge 1161 and the first ring body 111 is greater than the distance between the lower edge 1162 and the first ring body 111. It can be understood that from the upper edge 1161 to the lower edge 1162, the inner rim wall 1163 extends obliquely downward, thereby engaging with the guide surface 2221 of the protrusion 222, allowing the protrusion 222 to slide into the slot 113 along the gradually narrowing inner rim wall 1163.

[0060] To ensure the effective limiting and locking effect of the arc-shaped limiting member 114 on the spring arm 221, the top end of the first ring body 111, i.e., the initial extension end of the limiting member 114, is not lower than the lower edge 1162 of the surrounding edge 116. In this embodiment, the top end of the first ring body 111 is higher than or flush with the lower edge 1162, so that the limiting member 114 and the spring arm 221 are in radial interference fit without any offset or loosening in the height direction.

[0061] It should be noted that the bracket 1 has an arc-shaped groove 117 between the first ring 111 and the second ring 112, and the arc-shaped groove 117 is adjacent to the slot 113. Correspondingly, the face ring 2 is provided with a positioning part 23, which is located outside the light-emitting part 21. When the face ring 2 is installed on the bracket 1, the positioning part 23 is inserted into the arc-shaped groove 117 to achieve positioning and limiting functions.

[0062] The main body 13 of the bracket has a receiving cavity 130, and a lens 200 is installed in the receiving cavity 130. The lens 200 is first installed into the receiving cavity 130 of the bracket 1, and the face ring 2 is snapped onto the top of the bracket 1. At this time, the lower end of the light-emitting part 21 of the face ring 2 abuts against the lens 200 to ensure the stable installation position of the lens 200. An anti-glare ring 24 is provided on the inner side of the light-emitting part 21 of the face ring 2. The anti-glare ring is arranged in a stepped manner to reduce or eliminate glare.

[0063] The installation structure provided in this embodiment uses a snap-fit ​​method to install the face ring into the bracket. The bracket is equipped with an arc-shaped bending limiting component that is interference-fitted with the inner side of the elastic arm of the face ring, so that the face ring is locked to the bracket and cannot move, thus making it difficult to remove and reducing the risk of the face ring falling off.

[0064] Example 2

[0065] exist Figures 1-5 Based on reference Figures 6-8 This embodiment provides a lamp, including a lens 200, a lamp body 300, a light source assembly 400, and the mounting structure 100 of Embodiment 1. A receiving groove 121 is provided in the second mounting portion 12 of the bracket 1. The bracket 1 is fixedly connected to the lamp body 300 through the second mounting portion 12, and the light source assembly 400 is installed in the receiving groove 121.

[0066] Specifically, the lens 200 has a raised edge 201 at its upper end, and the support body 13 has a support platform 131 at its upper end, with the raised edge 201 positioned on the support platform 131. The support body 13 also has a groove 132, and correspondingly, the lens 200 has a positioning block. When the lens 200 is installed onto the support body 13, the positioning block is embedded in the groove 132. The face ring 2 is installed onto the support 1, and thus the face ring 2 abuts against the lens 200.

[0067] Furthermore, the second mounting part 12 is provided with a positioning post 122 facing the lamp body 300, and the lamp body 300 is provided with a corresponding mounting hole 301. The positioning post 122 is inserted into the mounting hole 301 for positioning and installation.

[0068] In some embodiments, the second mounting part 12 is further provided with a through hole 123, through which fasteners such as screws are fixedly installed in the fixing screw hole (not shown in the figure) provided in the lamp body after passing through the through hole 123, so as to realize the fixed connection between the bracket 1 and even the mounting structure 100 and the lamp body 300, making the whole lamp stable and reliable.

[0069] The lighting fixture in this embodiment can be assembled in the following manner:

[0070] Fix the light source assembly 400 on the base surface of the lamp body 300; install the bracket 1 on the lamp body 300, align the positioning post 122 and insert it into the mounting hole 301, and pass the fastener through the through hole 123 and lock it in the fixing screw hole, thereby fixing the bracket 1 to the lamp body 300.

[0071] The lens 200 is installed into the receiving cavity 130 of the bracket body 13, and the positioning block of the lens is embedded into the groove 132 of the bracket body to restrict the circumferential rotation of the lens 200.

[0072] The face ring 2 is installed into the bracket 1. The protrusion 222 at the end of the spring arm 221 engages with the guide surface 2221 and the inner wall 1163 of the surrounding edge, thereby locking into the slot 113. In the radial direction X, the limiting arc surface 115 of the limiting member 114 abuts against the first stop surface 2211 of the spring arm 221; in the height direction Y, the lower edge 1162 of the surrounding edge 116 abuts against the second stop surface 2222 of the spring arm 221. In this way, the locking part 22 is engaged with the first ring body 111 and the second ring body 1112 to form a "locked" installation structure. The face ring 2 is locked in the bracket 1 from all directions, and the face ring 2 and the bracket 1 are fixedly connected in a non-removable manner, preventing the face ring 2 from falling out of the bracket 1. The lower end of the face ring 2 also abuts against the upper end of the lens 200, restricting the up and down movement of the lens 200 and fixing the lens in place.

[0073] Example 3

[0074] exist Figures 1-8Based on, refer to Figure 9 This embodiment provides a lamp, including a lens 200, a lamp body 300, a light source assembly 400, a diffuser plate 500, and the mounting structure 100 of Embodiment 1. The lamp structure of this embodiment is basically the same as that of Embodiment 2, except that the lamp of this embodiment also includes a diffuser plate 500. The face ring 2 of this embodiment has a pre-reserved mounting groove 25 for mounting the diffuser plate 500. The diffuser plate 500 is mounted above the lens 200 and is located in the mounting groove 25 on the inner side of the lower end of the face ring 2, and is fixed by the face ring 2.

[0075] In the lamp provided in this embodiment, after the face ring is locked and installed onto the bracket, the face ring abuts against the lens, further locking the lens to prevent it from shifting and improving the installation stability of the optical components.

[0076] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
