[0046] The following embodiments of the utility model disclose a downlight, which provides a softer, more uniform and easy-to-install night light function while maintaining a slim design of the downlight.

[0047] The principle and implementation of a downlight of this embodiment will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the downlight of this embodiment without creative work.

[0048] See also Figure 1 As shown, this embodiment provides a downlight, which includes a back cover 1, an LED light board 2, a hollow surface ring 3, and a diffusion plate 4.

[0049] The bottom and side walls of the rear cover 1 form a cylindrical accommodating space; an opening is formed at one end of the side wall away from the bottom.

[0050] In some embodiments, the diameter of the cylindrical cross section gradually decreases from an end close to the hollow surface ring 3 to an end close to the bottom.

[0051] Specifically, as the cross-sectional diameter decreases, the light will be better focused and diffused when passing through the hollow surface ring 3 and the diffuser plate 4. At one end close to the hollow surface ring 3, the light is more effectively guided and controlled, forming a more concentrated lighting effect; while at the end close to the bottom, the light is evenly spread through the diffuser plate 4, forming a soft and uniform lighting. Secondly, this structural design can also improve the installation stability and safety of the downlight. The smaller diameter at the bottom makes it easier to embed the downlight into ceiling openings of different sizes, and it can be fixed in place more firmly, reducing the risk of the lamp falling off due to improper installation.

[0052] The hollow surface ring 3 is arranged at the opening of the rear cover; the hollow surface ring 3 includes an inner ring side wall 35 extending along the axial direction, and the inner ring side wall 35 is made of a light-transmitting material to allow the light of the LED light board to pass through.

[0053] Specifically, the hollow face ring 3 is arranged at the opening of the downlight back cover 1, and includes an inner ring side wall 35 extending in the axial direction. The inner ring side wall 35 is made of a light-transmitting material, so that the light of the LED light board can be efficiently transmitted, thereby forming a luminous circle illumination effect. This design not only provides balanced and comfortable lighting for the space, but also meets the aesthetic requirements of modern consumers for lighting products.

[0054] In some embodiments, the hollow surface ring 3 further includes an outer ring side wall 36 extending in the axial direction, and the outer ring side wall 36 is made of a light-transmitting material to allow the light of the LED light panel to pass through.

[0055] Specifically, in addition to the inner ring sidewall extending in the axial direction, the hollow face ring also includes an outer ring sidewall extending in the axial direction, which is also made of a light-transmitting material. When light passes through the inner ring sidewall 35 and the outer ring sidewall 36, each sidewall will form an independent light-emitting circle, which cooperate with each other to produce a unique visual and optical effect. This effect makes the downlight not just a single light source point, but a lighting device with multiple light levels.

[0056] Furthermore, the hollow surface ring 3 is a two-layer structure, including a lower panel 31 and an upper panel 32 , wherein the lower panel 31 is integrally formed with the outer ring side wall 36 and the inner ring side wall 35 of the hollow surface ring 3 , and the upper panel 32 is fixed on the lower panel 31 .

[0057] To enhance the fixation and alignment between the two panels, such as Figure 2As shown, a schematic diagram of the structure of the lower panel 31 and the upper panel 32 is shown. The lower panel 31 is evenly provided with a plurality of limiting holes 33 along its circumference, and the upper panel 32 is correspondingly provided with a plurality of protrusions 34. The limiting holes 33 cooperate with the protrusions 34 to ensure that the upper panel 32 and the lower panel 31 can be accurately aligned and firmly fixed during the assembly process.

[0058] At the same time, it also prevents the components from moving or falling off due to vibration or other external forces during use, thereby ensuring the long-term stability and safety of the lamp. In addition, this way of fixing the upper and lower panels also takes into account the convenience of maintenance and disassembly of the lamp, so that the lamp can be quickly and easily disassembled when the bulb needs to be replaced or maintenance is required.

[0059] In some embodiments, the lower panel 31 of the hollow outer ring 3 is designed to be very thin and made of a light-transmitting material. This thin design reduces the weight of the lamp.

[0060] The upper panel 32 can be made of non-light-transmitting material or light-transmitting material according to different lighting requirements.

[0061] Specifically, Figure 3 As shown in the figure, an exploded view of a downlight with an upper panel made of non-light-transmitting material is shown. In this embodiment, the downlight can present a visual effect of a double light ring. This design can effectively scatter light, thereby providing a uniform and soft lighting effect, significantly reducing glare, and is suitable for creating a warm and comfortable environment, such as homes, hotels, or hospital wards. In order to better illustrate the structure of the downlight at this time, as shown in the figure, Figure 4 As shown, a cross-sectional view of a downlight is shown.

[0062] Back to Figure 1 , showing an exploded view of a downlight with an upper panel made of translucent material. In this embodiment, since the lower panel 31 and the upper panel 32 are both made of translucent materials, the entire hollow surface ring 3 remains transparent, which has little effect on the color and intensity of the light. Therefore, the original light characteristics of the LED lamp beads can be maintained, so that the entire surface ring 3 emits uniform light. This design allows more light to pass directly through, creating a brighter lighting effect, and is suitable for occasions that require higher illumination and clear light, such as offices, shopping malls or exhibition halls. In order to better illustrate the structure of the downlight at this time, as shown in Figure 5 As shown, a cross-sectional view of a downlight is shown.

[0063] Furthermore, in order to simplify the production process and reduce the number of assembly steps, in some embodiments, the lower panel 31 and the upper panel 32 are integrally injection molded.

[0064] The diffusion plate 4 is disposed in the hollow portion of the hollow surface ring 3 .

[0065] Specifically, the main function of the diffuser plate 4 is to evenly disperse the light emitted from the LED light board 2. Since the light emitted by LED lamp beads is usually a point light source, direct irradiation may produce glare or uneven lighting effects. The diffuser plate 4 can refract, reflect and scatter light when passing through it through the microstructure or material properties of its surface, thereby achieving the purpose of softening the light, reducing shadows and improving the uniformity of lighting. In terms of material selection, the diffuser plate 4 is usually made of highly light-transmitting plastic or glass materials, which not only have good optical properties, but also ensure long-term durability and stability.

[0066] In addition, in this embodiment, the diffuser plate 4 is fixed to the hollow part of the hollow face ring 3, that is, it and the face ring 3 together seal the accommodating space, which can prevent dust and insects from entering the interior of the lamp, thereby protecting the LED lamp board 2 from pollution and damage.

[0067] The LED light board 2 is arranged at the bottom of the back cover 1 , and a plurality of night light beads 21 and a plurality of main light beads 22 are mounted on the LED light board 2 .

[0068] In some embodiments, the night light beads 21 are located on the LED light board 2 in a projection area corresponding to the hollow surface ring 3 ; the main light beads 22 are located on the LED light board 2 in a projection area corresponding to the diffuser plate 4 .

[0069] This partition design enables the night light beads 21 and the main light beads 22 to respectively assume different lighting roles. The night light beads 21 are responsible for providing auxiliary lighting, while the main light beads 22 are responsible for providing main lighting.

[0070] In order to optimize the lighting effect, the night light beads 21 and the main light beads 22 can be arranged according to a preset pattern.

[0071] For example, Figure 3 As shown, the night light beads 21 can be arranged into at least two concentric rings, and the night light beads 21 in each ring are evenly distributed. Similarly, the main light beads 22 can also be arranged into at least two concentric rings, and the main light beads 22 in each ring are evenly distributed.

[0072] In some embodiments, in order to achieve effective partitioning of the night light and the main light and optimize the propagation of light, a reflective cup 5 is further provided between the LED light board 2 and the hollow surface ring 3. The main function of the reflective cup 5 is to focus and guide the light emitted from the LED light board 2, reduce the scattering and loss of light, and thus improve the efficiency of light use. It is usually made of a material with high reflectivity, such as metal or high reflectivity plastic, to ensure that the light can be effectively reflected.

[0073] For example, Figure 6 As shown, the reflective cup 5 is provided with a buckle 51 , and the inner ring side wall of the hollow surface ring 3 is provided with a clamping point 52 corresponding to the buckle 51 . The buckle 51 and the clamping point 52 cooperate with each other to fix the reflective cup 5 and the hollow surface ring 3 .

[0074] like Figure 7 As shown, this fixing method of the buckle 51 and the clamping point 52 simplifies the assembly process of the downlight, so that the reflector cup 5 can be quickly and conveniently installed on the face ring 3. In addition, this fixing method has good reversibility, which is convenient for the maintenance and replacement of the lamp.

[0075] In summary, the utility model relates to a downlight, which can present one or two luminous apertures by selecting a light-transmitting material to make the side wall of the hollow surface ring. At the same time, by selecting the upper panel material of the hollow surface ring, the hollow surface ring can emit light on the entire surface or only on the two side walls, meeting different lighting needs and aesthetic preferences. In addition, the night light beads and the main light beads are mounted on an LED light board to simplify the circuit structure. In addition, the light guide outer ring, inner ring and reflective cup adopt a snap-on design to improve assembly efficiency and stability. The slim design of the light guide outer ring ensures the aesthetics after installation and the comfort of the indoor space.
