Examples of these embodiments are shown in the accompanying 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 accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] The supplementary light of this utility model embodiment refers to... Figures 1 to 4 The system includes a lamp holder and multiple LED lights 400. The lamp holder comprises a frame 100, a mounting plate 200, and a first light-transmitting plate 300. The frame 100 has an internal cavity 101 for housing an electric drive unit (not shown in the figure), which drives the LED lights to emit light. The mounting plate 200 is fixedly connected to the cavity 101 and has multiple light-emitting slots 210 arranged in a matrix. Each light-emitting slot 210 is bowl-shaped. The mounting plate 200 is made of a light-transmitting material. The surface of the mounting plate 200 and the inner side of the light-emitting groove 210 are both frosted. The first light-transmitting plate 300 is fixed in the frame 100 and covers the mounting plate 200. The multiple LED lights 400 and the multiple light-emitting grooves 210 correspond one-to-one. The LED lights 400 are built into the light-emitting grooves 210, and the light-emitting side of the LED lights 400 is correspondingly arranged with the first light-transmitting plate 300.

[0034] The light emitted by the LED light enters the corresponding bowl-shaped light-emitting groove 210. Within the light-emitting groove 210, the light is softened and diffused by the diffuse reflection of the frosted inner surface, spreading outwards. The light then passes through the mounting plate 200, made of translucent material with a frosted surface, where it undergoes further diffuse reflection, making the light more uniform. Finally, the light illuminates the first translucent plate 300 and is emitted to the outside. In summary, the structure of the bowl-shaped light-emitting groove 210 reflects and converges the light, expanding the illumination range; the frosted surface causes diffuse reflection, dispersing the concentrated light and softening it; the mounting plate 200 and the first translucent plate 300, made of translucent material, allow light to pass through while further scattering and homogenizing it. Based on the principles of light reflection, diffuse reflection, and transmission, the light is processed. The light emitted through the first translucent plate 300 effectively improves the display case's lighting effect. The secondary processing of the light during transmission avoids glare while ensuring lighting efficiency.

[0035] In some embodiments, refer to Figure 2 The first light-transmitting plate 300 is provided with a plurality of light-transmitting grooves 310, each of which is spherical. Each light-transmitting groove 310 corresponds one-to-one with a light-emitting groove 210, and the light-transmitting groove 210 covers the top of the light-transmitting groove 310. The light emitted by the LED lamp is softened and amplified within the light-emitting groove 210 before propagating upwards to the spherical light-transmitting groove 310 of the first light-transmitting plate 300. Within the light-transmitting groove 310, the light undergoes reflection and refraction by the spherical surface, further adjusting the direction of light propagation and making the light emitted more evenly to the outside.

[0036] In some embodiments, refer to Figure 1The frame 100 includes a main body 110 and a plug 120. The main body 110 is elongated. The receiving cavity 101 is disposed in the main body 110. On the cross-section of the main body 110, the two inner sides of the upper end of the receiving cavity 101 are provided with slots 111. The two sides of the first light-transmitting plate 300 are respectively embedded in the slots 111 on both sides. The plug 120 is fixedly connected to both ends of the main body 110. The plug 120 is sleeved on the main body 110 so that the mounting plate 200 and the first light-transmitting plate 300 are constrained in the main body 110. When installing the frame 100, firstly, the two sides of the first light-transmitting plate 300 are embedded into the slots 111 on the inner side of the upper end of the receiving cavity 101 of the main body 110. Then, the mounting plate 200 is placed in a suitable position within the receiving cavity 101. Finally, the plugs 120 are fixed to both ends of the main body 110. By fitting the plugs 120 onto the main body 110, the mounting plate 200 and the first light-transmitting plate 300 are tightly constrained within the main body 110, forming a complete frame 100 structure. This structural design makes the assembly of the frame 100 more convenient and faster. The slots 111 are used to position and initially fix the first light-transmitting plate 300. The connection between the plugs 120 and the main body 110 constrains the mounting plate 200 and the first light-transmitting plate 300. By utilizing the fastening principle of the mechanical structure, the stable installation of each component is achieved, ensuring the overall structural strength of the frame 100.

[0037] In some embodiments, refer to Figure 1 The frame 100 is rotatably connected to both ends with swing arms 130, and a connecting part 131 is provided at the end of the swing arm 130 away from the frame 100. The connecting part 131 is used to connect to the display case and fix the entire supplementary light. Specifically, the rotatable connection of the swing arm 130 allows the supplementary light to be flexibly adjusted in angle and position to adapt to the installation requirements and lighting angle requirements of different display cases.

[0038] Preferably, a synchronous connecting rod 132 is fixedly connected between the two swing arms 130. The synchronous connecting rod 132 ensures the synchronous movement of the two swing arms 130, making the frame 100 more stable and balanced when adjusting the angle, and avoiding the displacement of the supplementary light position or structural instability caused by the inconsistent rotation of the swing arms 130.

[0039] In some embodiments, a heat dissipation rib 140 is provided on the side of the frame 100 away from the first light-transmitting plate 300. The heat dissipation rib 140 has a large surface area and can exchange heat with the surrounding air, dissipating heat into the air, thereby reducing the temperature of the frame 100 and its internal components.

[0040] In some embodiments, the LED lamp 400 includes a lamp housing 410, a mounting base 420, an aluminum substrate 430, and an end cap 440. The lamp housing 410 has an internal cavity. In the cross-section of the lamp housing 410, the diameter of the cavity gradually increases from bottom to top. The sidewalls of the cavity are arc-shaped. A lamp head 411 is provided at the top of the lamp housing 410, and the upper end of the lamp housing 410 is open. The mounting base 420 is located within the cavity. The mounting base 420 is disc-shaped and coaxial with the lamp housing 410. The edge of the base 420 is bent upward to form a first connecting section 421, and the edge of the first connecting section 421 is bent outward to form a second connecting section 422. The second connecting section 422 abuts against the inner sidewall of the cavity. An aluminum substrate 430 is fixed to the bottom surface of the mounting base 420, and a plurality of lamp beads 431 are laid on the surface of the aluminum substrate 430. An end cap 440 is provided with a second light-transmitting plate 441, and the end cap 440 is fixed to the opening at the upper end of the lamp housing 410. A heat-conducting hole 442 is provided through the end cap 440. The LED bead 431 emits light on the aluminum substrate 430. The light propagates upward through the space around the mounting base 420. After being reflected and guided by the arc-shaped sidewall of the lamp housing 410, the light converges towards the top of the lamp housing 410 and is then emitted through the second light-transmitting plate 441 on the end cover 440. At the same time, the heat generated by the aluminum substrate 430 is transferred to the cavity sidewall of the lamp housing 410 through the mounting base 420 and then dissipated to the outside through the heat conduction hole 442 on the end cover 440. The heat can be transferred to the frame 100 and finally dissipated into the air through the heat dissipation ribs 140.

[0041] In some embodiments, multiple heat-conducting holes 442 are provided, and the multiple heat-conducting holes 442 are equidistantly spaced around the center of the end cover 440. The multiple equidistant heat-conducting holes 442 increase the heat dissipation channels, allowing heat to be dissipated more quickly and evenly, avoiding local overheating of the end cover 440, further improving the heat dissipation performance of the LED lamp, and ensuring its stable operation.

[0042] In some embodiments, a gap 443 is provided between the second light-transmitting plate 441 and the aluminum substrate 430. The gap 443 provides a space for light diffusion, making the light softer based on the principle of light scattering; the air channel formed by the gap 443 promotes airflow using the principle of heat convection, helping to dissipate the heat generated by the aluminum substrate 430 and the lamp beads 431.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
