DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is any conflict, the embodiments and features in the embodiments described below can be combined with each other in any manner.

[0036] Many different implementations or examples are provided below to implement the structure of the present invention.

[0037] See also Figures 1-9, a lamp according to an embodiment of the present invention can be a downlight, a spotlight or a downlight, the lamp includes a radiator 1, the radiator 1 is generally made of aluminum to improve its structural strength and heat dissipation effect, the radiator 1 has a cavity; a light source 2, the light source 2 can be an LED lamp bead, the light source 2 is arranged in the cavity of the radiator 1, the specific fixing method is a well-known technology, which will not be elaborated here; a lens 3 is arranged above the light source 2 and opposite to the light source 2, the lens 3 is used to optimize the light output angle after the LED lamp bead emits light, in other embodiments, a small reflective cup can also be used to replace the lens to achieve the purpose of optimizing the light output angle; a reflective cup 4 is connected to the radiator 1, the specific connection structure is a well-known technology, a plug-in piece 5 is provided on the side wall of the reflective cup 4, the plug-in piece 5 can be integrally formed with the reflective cup 4; a face ring 6, a slot 61 is provided on the face ring 6, the slot 61 is plugged into the plug-in piece 5, and the face ring 6 is fixed to the reflective cup 4 through the plug-in connection. For details, see Figure 1-Figure 3 as well as Figure 9 As shown, in some embodiments of the present invention, a retaining spring 7 is further included. The retaining spring 7 has an insert plate 71 that is inserted into the slot 61 to secure the retaining spring 7. During assembly, after the reflector 4 is mounted on the heat sink 1, the slot 61 is aligned with the insert plate 5 and then pushed in, so that the insert plate 5 is inserted into the slot 61. At this point, the face ring 6 is installed. The insert plate 71 is then aligned with the slot 61 and inserted into the face ring 6 to complete the installation and fixation of the retaining spring 7 to the face ring 6. This is convenient and quick, and can be completed manually by workers without the need for tools. This significantly improves assembly efficiency and eliminates the prior art method of installing the face ring and retaining spring by screws or rivets. This eliminates the rivet or screw connection process, thereby improving assembly efficiency and reducing production costs. Since the face ring is connected to the insert plate on the reflector and the insert plate on the retaining spring through the slot on it, the plug-in structure is not exposed, and there is no exposed screws or rivets as in the prior art structure. This improves the integrity and appearance of the lamp, thereby helping to avoid lamp homogeneity and enhance the market competitiveness of the lamp. In order to ensure the reliability of the installation of the face ring 6 on the reflective cup 4 and to ensure uniform force, in this embodiment, there are two groups of the plug-in pieces 5 and the slots 61 , which are arranged at 180° relative to each other.

[0038] See Figure 5-Figure 8 As shown, in some embodiments of the present invention, the plug-in piece 5 is connected to the reflective cup 4 through a connecting column 51, and a first avoidance notch 62 is provided on the groove wall of the slot 61 to avoid the connecting column 51. As a result, the plug-in piece 5 can be inserted more deeply into the slot 61, and the height of the face ring 6 can be fully utilized to set the slot 61, so that the connection of the face ring 6 to the reflective cup 4 is more reliable.

[0039] See Figure 5-Figure 8 As shown, in some embodiments of the present invention, the plug-in piece 5 includes a root 52 connected to the connecting column 51, and a cantilever 53 connected to the root 52, and the root 52 abuts against the groove wall of the slot 61, so that the connecting column 51 will not detach from the first avoidance gap 62 along its axial direction, and the thickness of the cantilever 53 is smaller than the groove width of the slot 61, so that the cantilever 53 can be deformed in the slot 61, and a protrusion 54 is provided on the cantilever 53, and a plurality of teeth 63 are provided on the groove wall of the slot 61. When the face ring 6 is rotated, the protrusion 54 can switch between different teeth 63. The root 52 and the slot 61 can be clamped to avoid looseness or shaking between the plug-in piece 5 and the slot 61; the arrangement of the cantilever 53, the protrusion 54 and the plurality of tooth grooves 63 makes it possible for some lamps to adjust the light output angle of the lamp by rotating the face ring 6 (the face rotates around the connecting column 51). When the face ring 6 rotates relative to the reflective cup 4, when the protrusion 54 is in the tooth protrusion position, the cantilever 53 can be deformed, thereby allowing the protrusion 54 to pass over the tooth protrusion and enter the next tooth groove 63. In addition, such a structure can achieve a clicking sound when the face ring 6 rotates, thereby improving the high-end feel and operating feel of the lamp. At the same time, when the face ring angle is adjusted to the right position, the cooperation between the protrusion 54 and the tooth groove 63 can lock the face ring position.

[0040] In some embodiments of the present invention, see Figure 9 As shown, the insert plate 71 is provided with a second relief notch 72 that avoids the root portion 52. This allows the insert plate 71 to be inserted deeper into the slot 61, increasing the contact area between the insert plate and the slot, thereby improving connection reliability. Furthermore, when the insert plate 71 is fixed in the slot 61, the insert plate 71 forms a vertical limit for the root portion 52, making it more difficult for the plug-in piece 5 to loosen in the vertical direction and even fall out of the slot 61.

[0041] See Figure 9 As shown, in order to facilitate the insertion of the plug-in board 71, in some embodiments of the present invention, guide oblique walls 73 are provided on both sides of the plug-in board 71, and the guide oblique walls 73 are tightly matched with the groove walls of the slot 61. The guide oblique walls 73 have a guiding function, which facilitates the quick insertion of the plug-in board 71 into the slot 61 in a blind plugging manner. A sharp portion 74 is provided on the oblique wall 73, and the sharp portion 74 abuts against the groove wall of the slot 61. The plug-in board 71 is generally made of metal materials such as stainless steel. During assembly, the plug-in board 71 is knocked into the slot 61, and the sharp portion 74 can pierce the groove wall of the slot 61, making the connection of the plug-in board 71 in the slot 61 more reliable.

[0042] See Figure 3As shown, in some embodiments of the present invention, the face ring 6 is provided with an inclined surface 64 at the light outlet, and the inclined surface 64 connects with the reflective concave surface of the reflector cup 4. In the prior art, the mouth of the reflector cup 4 is substantially flush with the upper end surface of the face ring, so that the connection between the reflector cup 4 and the face ring 6 is directly exposed on the end surface on the light outlet side of the lamp (that is, in the prior art, the inclined surface 64 is part of the reflector cup 4), affecting the integrity and aesthetics of the lamp. However, the structure described in this embodiment allows the connection between the reflector cup 4 and the face ring 6 to be retracted, improving the aesthetics of the lamp.

[0043] like Figure 1 As shown, in some embodiments of the present invention, the cross section of the heat sink 1 is triangular, and the corners of the triangle are arc-shaped transitions, so that the lamp has a stronger three-dimensional layering and a better appearance.

[0044] See Figure 1 As shown, in some embodiments of the present invention, a wire hole 11 is provided on the radiator 1, and the wire hole 11 is provided on the side wall of the radiator 1. A back cover 12 is provided on the radiator 1, thereby making the back cover 12 a universal part, and the back cover 12 can be suitable for more styles of lamps.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
