DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0054] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0055] Please refer to Figure 1 This embodiment provides a lamp 010, which may refer to an LED downlight; of course, in other embodiments, the lamp 010 may also refer to a desk lamp, etc., which is not specifically limited here.

[0056] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The lamp 010 includes a reflector cup assembly 100 and a light source mechanism 200. The reflector cup assembly 100 is provided with a rotating shaft 113. The light source mechanism 200 is provided with a rotating portion 211. The rotating portion 211 includes a slot 212 and a hollow structure 213 distributed on the periphery of the slot 212. The rotating shaft 113 and the slot 212 are rotatably plugged in and matched. The hollow structure 213 is used to make the groove wall of the slot 212 elastically deform. The light emitted by the light source mechanism 200 can be reflected and emitted through the reflector cup assembly 100.

[0057] By plugging and fitting the rotating shaft 113 and the slot 212, the light source mechanism 200 and the reflector cup assembly 100 can rotate relative to each other to adjust the direction of light emission, and a hollow structure 213 is provided on the periphery of the slot 212 so that the slot wall of the slot 212 can be elastically deformed when squeezed by an external force to form an avoidance effect, thereby ensuring that when one of the reflector cup assembly 100 and the light source mechanism 200 is subjected to force and rotates relative to the other, the force applied is uniform, thereby ensuring the smoothness of the relative rotation; moreover, through the design of the hollow structure 213, the shrinkage deformation problem caused by the thickness of the injection molding glue can be improved during injection molding.

[0058] Of course, in other embodiments, the light source mechanism 200 is provided with a rotating shaft 113 , and the reflective cup assembly 100 is provided with a rotating portion 211 .

[0059] Furthermore, the wall of the slot 212 is closely attached to the outer periphery of the shaft 113 to form an interference fit; for example, the diameter of the shaft 113 is 4 mm, and the diameter of the slot 212 is 3.9 mm. This arrangement can improve the stability of the light source mechanism 200 and the reflector cup assembly 100 being assembled together through the shaft 113 and the slot 212.

[0060] Of course, in other embodiments, the rotating portion 211 may not be provided with the hollow structure 213; or, in other embodiments, the reflective cup assembly 100 and the light source mechanism 200 may be fixedly connected in a non-rotatable manner.

[0061] The structure of the reflector cup assembly 100 is set as required; please refer to Figure 6 and Figure 7In this embodiment, the reflector cup assembly 100 includes a reflector cup 110, and the reflector cup 110 includes a reflector cup body 111 and a connector 112. The first end of the connector 112 is connected to the reflector cup body 111, and the second end of the connector 112 is connected to a rotating shaft 113. A hollow portion 114 is provided between the first end and the second end of the connector 112. The reflector cup body 111 is trumpet-shaped, and its inner diameter gradually decreases along its axial direction. The end with a smaller inner diameter of the reflector cup body 111 is a constricted end, and the end with a larger inner diameter is an expanded end. The first end of the connector 112 is connected to the expanded end, and the second end of the connector 112 extends toward the constricted end along the axial direction of the reflector cup body 111. Since the hollow portion 114 is provided between the first end and the second end of the connector 112, so that the connector 112 forms a suspended structural design, the problem of shrinkage deformation caused by a thicker thickness can be improved when the reflector cup 110 is injected.

[0062] For further information, please refer to Figure 8 The connecting piece 112 is integrally injection molded with the reflector cup body 111; the connecting piece 112 has a side facing the reflector cup body 111 and a side away from the reflector cup body 111, and there is a gap between the side of the connecting piece 112 facing the reflector cup body 111 and the reflector cup body 111, and the hollow portion 114 provided on the connecting piece 112 is relatively distributed with the outer side wall of the reflector cup body 111. Such arrangement ensures that only the position where the first end of the connecting piece 112 is connected to the reflector cup body 111 is in contact with the reflector cup body 111, and the other positions are equivalent to being suspended. No other structures are required to be arranged on the reflector cup body 111, which is beneficial to improving the quality and stability of injection molding. That is, the connecting piece 112 is in contact with the reflector cup body 111 only at the position where it is connected to the reflector cup body 111, and the other positions are suspended relative to the reflector cup body 111. Therefore, other structures on the reflector cup body 111 are reduced. When the reflector cup 110 is injection molded, the corresponding position of the reflector cup body 111 can ensure that the flow of the rubber is not hindered by other structures due to the reduction of the presence of other components, thereby improving the fluidity of the rubber, which is beneficial to improving the appearance of the reflector cup with defects such as flow lines and stratification, and improving the quality and stability of the injection molding of the reflector cup 110.

[0063] Optionally, see Figure 6 , Figure 7 and Figure 8 The reflector cup 110 further includes a reinforcing rib 115, and the reinforcing rib 115 is connected between the rotating shaft 113 and the connecting member 112. The provision of the reinforcing rib 115 can improve the stability of the connection between the rotating shaft 113 and the connecting member 112, improve the problem of fracture and deformation of the rotating shaft 113, and further improve the stability of the assembly of the reflector cup assembly 100 and the light source mechanism 200.

[0064] Optionally, see Figure 6 and Fig. 9The reflector cup assembly 100 further includes an elastic member 130, which has a connecting end and a free end. The connecting end is plugged into the second end of the connector 112, and the free end is used to cooperate with the installation position of the lamp 010. By setting the elastic member 130, the lamp 010 can be assembled on the installation position such as the ceiling without using fasteners such as bolts.

[0065] For further information, please refer to Figure 6 and Fig.10 The elastic member 130 includes a torsion spring 131, a first connecting arm 132, a second connecting arm 133 and a matching member 134. The matching member 134 is connected to the torsion spring 131 through the first connecting arm 132, and one end of the second connecting arm 133 is connected to the matching member 134; the second end is connected to the plug-in arm 117, and the plug-in arm 117 is provided with a limiting groove 118. The torsion spring 131 is plugged and matched with the plug-in arm 117, and the other end of the second connecting arm 133 is plugged and matched with the limiting groove 118; specifically, the connecting end of the first connecting arm 132 is respectively connected to the matching member 134 and one of the torsion arms of the torsion spring 131, and the other torsion arm of the torsion spring 131 The second connecting arm 133 can be connected (e.g., abutted) or distributed with a gap with the second end of the connecting member 112. One end of the second connecting arm 133 is connected to the matching member 134, and the other end is bent and extends into the through hole of the torsion spring 131, so that when the torsion spring 131 is plugged and matched with the plug-in arm 117, it is ensured that the end of the second connecting arm 133 away from the matching member 134 can be reliably plugged with the limiting groove 118, and can rotate in the limiting groove 118, so as to achieve reliable limiting, and improve the problem of displacement and jamming of the second connecting arm 133 when rotating under the action of external force, so as to improve the reliability and smoothness of assembling the lamp 010 using the elastic member 130. In this way, it can be ensured that the matching member 134 can reliably match with the installation position of the lamp 010 under the action of the torsion spring 131, so as to ensure the reliability of the lamp 010 being assembled in the corresponding installation position.

[0066] Optionally, two plug-in arms 117 are connected to the second end of the connector 112, and the two plug-in arms 117 are spaced apart so that the gaps between the rotating shaft 113 and the two plug-in arms 117 are relatively distributed; one of the plug-in arms 117 is provided with a limiting groove 118, and the two plug-in arms 117 are respectively plugged into the torsion spring 131 from both ends of the through hole of the torsion spring 131. In this way, on the one hand, the easy assembly of the torsion spring 131 can be ensured, and on the other hand, the stability of the assembly of the torsion spring 131 to the connector 112 can be ensured, that is, the stability of the assembly of the elastic member 130 to the connector 112 can be ensured.

[0067] The number of elastic members 130 can be selected as needed. The lamp 010 of this embodiment includes two relatively distributed elastic members 130. Of course, in other embodiments, the number of elastic members 130 can also be one, three, four, etc., which is not specifically limited here.

[0068] Optionally, see Figure 6 and Figure 7 The reflector cup assembly 100 further includes a face ring 120, which has a mounting portion, the reflector cup body 111 and the connector 112 are both plugged into the mounting portion, and the connector 112 is snap-fitted with the face ring 120. The face ring 120 can hide most of the connector 112, which improves the aesthetics on the one hand, improves the problem of the connector 112 being easily damaged on the other hand, and improves the problem of the rotation shaft 113 provided on the connector 112 being plugged into the slot 212, thereby ensuring the stability and reliability of the light source mechanism 200 and the reflector cup assembly 100 being assembled together.

[0069] Furthermore, the second end of the connector 112 is provided with a latch 119, and when the connector 112 and the reflector cup body 111 are both plugged into the mounting portion, the second end of the connector 112 extends out of the mounting portion so that the latch 119 is engaged with the end of the face ring 120. In this way, easy assembly and stability after assembly can be ensured.

[0070] Further, please refer to Figure 6 , Figure 7 and Fig. 9 The plug arm 117 extends out of the mounting portion so that the elastic member 130 is distributed outside the cover. In this way, the lamp 010 can be easily assembled at the corresponding mounting position using the elastic member 130.

[0071] Optionally, the mounting portion of the face ring 120 is a through-hole structure.

[0072] Of course, in other embodiments, at least one of the reflector cup body 111 and the connector 112 may also be bonded to the face ring 120 , etc., which is not specifically limited here.

[0073] Optionally, see Figure 6 and Figure 7 The connecting member 112 is provided with a guide groove 116, and the face ring 120 is provided with a guide rib 121, and the guide rib 121 is plugged into the guide groove 116; specifically, the connecting member 112 is provided with a guide groove 116 on a side away from the reflector cup body 111, and the hole wall of the mounting portion is provided with a guide rib 121. The cooperation between the guide groove 116 and the guide rib 121 can improve the accuracy and efficiency of assembly.

[0074] Of course, in other embodiments, the face ring 120 is provided with a guide groove 116, and the connecting piece 112 is provided with a guide rib 121, and the guide rib 121 is plugged into the guide groove 116; or, in other embodiments, the guide rib 121 or the guide groove 116 can also be provided on the reflector cup body 111.

[0075] The structure of the light source mechanism 200 can be set as required; please refer to Fig.11 and Fig.12 The light source mechanism 200 of the present embodiment includes a lens ring 210, and the lens ring 210 is provided with a limiting rib 215 and a rotating part 211. The limiting rib 215 abuts against the connecting member 112 to prevent the connecting member 112 from shrinking inwards toward the central axis of the reflector cup body 111. In this way, the limiting rib 215 can be used to ensure the relative position stability of the rotating shaft 113 connected to the connecting member 112, and thus ensure the stability of the assembly of the rotating shaft 113 and the slot 212, that is, to improve the problem that the connecting member 112 is easily deformed and causes the displacement of the rotating shaft 113, thereby ensuring the relative rotation stability and assembly stability between the light source mechanism 200 and the reflector cup assembly 100, and also improve the problem that the connecting member 112 shrinks and breaks, thereby further improving the connection reliability of the connecting member 112 and the lens ring 210.

[0076] Optionally, see Fig.11 The hollow structure 213 includes a hollow hole 214 provided in the lens ring 210 , and the shape of the hollow hole 214 can be adapted to the shape of the slot 212 , so as to ensure the reliability of elastic deformation of the slot wall 212 under the action of external force.

[0077] The number of hollow holes 214 can be selected as needed; please refer to Fig.11 and Fig.13 In this embodiment, the rotating part 211 further includes a support rib 240 and two elastic arms 241. The support rib 240 is connected to the lens ring 210. One end of the two elastic arms 241 is connected to the support rib 240. The other ends of the two elastic arms 241 extend away from the support rib 240. The support rib 240 and the two elastic arms 241 together form a slot 212. The side of the elastic arm 241 away from the slot 212 has a hollow structure 213. The support rib 240 can provide certain support to the elastic slot wall of the slot 212 to ensure the reliability of the rotation shaft 113 plugged into the slot 212.

[0078] Furthermore, the rotating portion 211 also includes a connecting rib 242, which is roughly U-shaped.
