Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to a lighting component and a lighting fixture. Background Art

[0002] As a lighting fixture, lamps play an important role in our daily lives. Among them, the simplification of lamp structure and diversification of functions can bring a better experience to consumers and also play an important role in reducing production costs.

[0003] Currently, reflectors that combine heat dissipation and shading functions have appeared on the market, in order to achieve good lighting effects while reducing costs, achieving the goal of balancing lighting and energy conservation and environmental protection. However, in the current lighting assemblies composed of reflectors and light source components, the light-emitting units of the light source components are centrally arranged, and a single reflector is used to jointly shade and dissipate heat for the concentrated light source components, resulting in the reflector's role not being fully utilized. If the light source components are further dispersed according to the traditional arrangement in order to improve the function of the reflector, the size of the aluminum substrate will become larger, increasing the production cost of the lighting assembly. In order to ensure the lighting effect, the size of the lens or diffuser used to control the light of the light source component will also become larger, further increasing the overall volume and production cost of the lighting assembly.

[0004] Therefore, how to provide a lighting structure that is low-cost and has good heat dissipation effect is an urgent problem to be solved by people in the current related technical fields. Utility Model Content

[0029] 1. The utility model provides a lighting assembly, which realizes a simplified structure while having low cost and high heat dissipation effect by arranging the light source, lens and reflector into a structure in which the main body extends along the Archimedean spiral. Specifically, the uniform distribution of the light-emitting units along the Archimedean spiral can realize the uniform dispersion of the light-emitting units, so that the light-emitting units located at the center of the light source and the light-emitting units located at the edge have good heat dissipation space, narrowing the gap in heat dissipation effect between the center and the edge of the light source, thereby improving the heat dissipation effect of the lighting assembly.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] Example 1:

[0049] Please see the attached Figure 1-5 This embodiment provides a lighting assembly 100, including a light source 1, a lens 2, and a reflector 3. By optimizing the light source 1, the lens 2, and the reflector 3, the lighting assembly 100 simplifies the overall structure, improves heat dissipation, and reduces production costs.

[0050] Figure 1 An exploded schematic diagram of the lighting assembly 100 is provided. Figure 2 A schematic diagram of the structure of the light source 1 is given. Figure 1 and Figure 2 The lighting assembly 100 includes a light source 1, a lens 2 and a reflector 3. The light source 1 includes a base 4 formed by extending along the Archimedean spiral and light-emitting units 11 provided on the base 4. The light-emitting units 11 are evenly distributed along the Archimedean spiral. In the direction of the Archimedean spiral curve, the spacing between adjacent light-emitting units 11 is the same; in the direction of the radius of the circle formed by extending along the Archimedean spiral coil layer, the spacing between the light-emitting units 11 of adjacent circles is the same, so the light-emitting units 11 in the lighting assembly 100 have a uniform dispersion feature. Each light-emitting unit 11 has a similar heat dissipation space, which is conducive to achieving uniform heat dissipation and avoiding the situation where the heat dissipation effect of the center of the light source 1 and the edge of the light source 1 is too different, thereby further improving the heat dissipation effect of each light-emitting unit 11 of the lighting assembly 100.

[0051] The lighting assembly 100 further includes a lens 2 covering the light emitting unit 11. Figure 3 A top view of the lighting assembly is given. Figure 4Given Figure 3 Partial cross-sectional view of the lighting assembly 100 along line AA. Figure 4 As shown, the lens 2 includes a light control body 21 and a light entrance cavity 22. The light-emitting unit 11 is located in the light entrance cavity 22, and the light emitted by the light-emitting unit 11 enters the light control body 21 through the light entrance cavity 22. The light is processed by the light control body 21 and then emitted from the lens 2. The light control body 21 in the lens 2 can be an independent structure distributed along the Archimedean spiral and adapted to each light-emitting unit 11.

[0052] In this embodiment, the lens 2 is preferably an integral injection-molded structure formed by continuously extending the light-control body 21 along the Archimedean spiral. The lens 2 covers all the light-emitting units 11 along the Archimedean spiral, and finely controls the light emitted by the light-emitting units 11. Compared with a lens of the same size that uniformly controls the light emitted by the centrally arranged light-emitting units, the lens 2 extending along the Archimedean spiral can save about 2 / 3 of the material. Accordingly, in the process of manufacturing the lens 2, through reasonable production planning, it is possible to simultaneously prepare multiple lenses 2 with Archimedean spiral extensions on a unit area of ​​the lens 2 raw material, thereby effectively improving the utilization rate of the raw material of the lens 2, saving the material of the lens 2, reducing the production cost and improving production efficiency.

[0053] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 A reflector 3 is also provided on the outside of the lens 2. The reflector 3 comprises a reflective body 31 extending along an Archimedean spiral and a reflective groove 32 defined within the body 31. The light source 1 and lens 2 are positioned within the reflective groove 32, allowing the reflective body 31 to control light emitted from the side of the light source 1 and provide an anti-glare effect. Light emitted from the light source 1 passes through the lens 2 and the reflector 3 before exiting.

[0054] Specifically, the light incident cavity 22 is provided with a light incident port 23 disposed toward the base 4 , and the reflective groove 32 is provided with a light exit port 33 disposed away from the base 4 .

[0055] The light source 1 is fixedly connected to the reflective body 31 via the base 4. The lens 2 covers the periphery of the light-emitting unit 11, positioning the light-emitting unit 11 at the light entrance 23 of the lens 2. The reflective body 31 is positioned entirely outside the light source 1 and lens 2. Light emitted by the light source 1 passes through the lens 2 before exiting. Some of the light emitted from the lens 2 is reflected by the inner surface of the reflective body 31 before exiting the light exit 33. Some of the light passes directly through the reflective groove 32 and exits the light exit 33.

[0056] In this embodiment, the reflective body 31 includes a sidewall 35 and a first end 311 and a second end 312, respectively, disposed at either end of the sidewall 35. The first end 311 is located adjacent to the light-emitting surface of the light-emitting unit 11, and a light outlet 33 is provided at the first end 311 of the reflective body 31. The second end 312 of the reflective body 31 is provided with a base plate 315 for connection and fixation with the light source 1. The base plate 315 is connected to the sidewall 35. In a cross section passing through the center of the lighting assembly 100 and perpendicular to the plane of the base plate 315, the reflective body 31 exhibits a trapezoidal cross-section in a single circle. Specifically, the first end 311 is wider than the second end 312. Light emitted from the side of the lens 2 is reflected by the inner surface of the sidewall 35 and then emitted from the light outlet 33, thereby reducing glare generated by the lighting assembly 100 and improving the lighting effect of the lighting assembly 100.

[0057] In particular, traditional lighting components typically use a single reflector and uniformly perform shading, anti-glare, and heat dissipation functions on all light sources concentrated within the reflector. The reflector 3 in this embodiment, however, uses a reflective body 31 extending along the same path as the light-emitting unit 11. Compared to traditional reflectors, the reflector 3 in this embodiment can achieve refined shading, anti-glare, and heat dissipation effects on the light-emitting unit 11. While ensuring a good lighting effect, the height of the reflective body 31 can also be reduced, giving the reflector 3 a flattened characteristic. This helps reduce the use of heat dissipation materials, helps reduce packaging materials, and thus reduces transportation costs. At the same time, the reflective body 31 extending along the Archimedean spiral can promptly conduct heat to the light-emitting unit 11, thereby improving heat dissipation efficiency.

[0058] Furthermore, because the light-emitting units 11 are evenly dispersed and provide excellent heat dissipation, the heat dissipation area required by the reflective body 31 can be reduced accordingly, thereby reducing the heat dissipation material required for the reflector 3 and further reducing production costs. Furthermore, the design of the light-emitting units 11 and the reflective body 31 extending along the Archimedean spiral as a whole also provides better heat dissipation than traditional lighting components.

[0059] It should be noted that to ensure that the reflector 3 has good light-shielding and anti-glare effects, the height of the reflective body 31 is adapted to the height of the lens 2. That is, in the overall direction of light emission, the light-emitting vertex of the lens 2 does not protrude beyond the light-emitting port 33, ensuring that the reflective body 31 fully regulates the light emitted from the side of the lens 2. The light-emitting vertex refers to the position of the reflector 21 away from the vertex of the light-emitting unit 11.

[0060] In some embodiments, the reflector 3 further includes a connecting body 34. The reflector body 31 extends along an Archimedean spiral, and the connecting body 34 is used to connect the reflector bodies 31 of adjacent layers. When assembling the lighting assembly 100, screws or glue can be added to the connecting body 34 to secure the reflector 3. In other embodiments, the reflector body 31 can be formed by a protrusion or depression on the connecting body 34.

[0061] In particular, in order to obtain a good lighting effect, this embodiment further defines the structures of the light source 1, lens 2 and reflector 3. Figure 6 In this embodiment, the lighting assembly 100 is arranged as a whole along the Archimedean spiral, with the plane where the bottom plate 315 is located as the base plane, and the projection point of the center of the lighting assembly 100 on the base plane as the origin O;

[0062] The horizontal axis passing through the origin O is the X-axis, and the vertical axis passing through the origin O is the Y-axis. Any point A on the extension path of the lighting assembly 100 along the Archimedean spiral has coordinates (x, y). The coordinates of point A have the following relationship:

[0063] x=a*(t*sin(t)+cos(t))

[0064] y=a*(sin(t)-t*cos(t));

[0065] Where a is a constant of the lighting assembly size, which is related to the maximum width of the lighting assembly 100 and is greater than 0; t is the number of revolutions of the Archimedean spiral of the lighting assembly 100. To achieve excellent lighting and heat dissipation effects, the value of a is preferably in the range of 20-30.

[0066] In some embodiments, along the distribution path of the light-emitting units 11 on the substrate 4 , the spacing between adjacent light-emitting units is preferably 8-25 mm to obtain good lighting and heat dissipation effects.

[0067] In particular, similar to the lens 2, multiple substrates 4 with extended Archimedean spirals can be prepared simultaneously on a unit area of ​​the substrate 4 raw material, thereby effectively improving the utilization rate of the substrate 4 raw material, which is beneficial to saving the material of the substrate 4, reducing production costs and improving production efficiency.

[0068] In this embodiment, the substrate 4 may be an aluminum substrate 4 .

[0069] Example 2:

[0070] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the lighting assembly 100. For the similarities, please refer to embodiment 1. The improvements are further described below.

[0071] Please refer to Figure 7 In this embodiment, the sidewalls 35 of the reflective body 31 include a first sidewall 351 and a second sidewall 352, which are respectively provided on either side of the lens 2. The first sidewall 351 and the second sidewall 352 both extend along an Archimedean spiral. The first sidewall 351 and the second sidewall 352 can be planar or curved.

[0072] In this embodiment, the first side wall 351 and the second side wall 352 are curved structures that protrude toward the interior of the reflective groove 32 to ensure sufficient light control. It is understood that in some embodiments, the first side wall 351 and the second side wall 352 can also be curved structures that protrude toward the exterior of the reflective groove 32.

[0073] It should be noted that the starting end and the terminal end of the reflective body 31 extending along the Archimedean spiral may be a closed structure to further improve the anti-glare effect.

[0074] Example 3:

[0075] This embodiment provides a lamp based on the above embodiment. The lamp can be a downlight, a flat panel light, or a ceiling light, etc. This embodiment uses a ceiling light as an example for description. For similarities, please refer to Embodiment 1 or Embodiment 2.

[0076] A lamp comprises a lamp body and a lighting assembly 100 installed inside the lamp body. The lighting assembly 100 comprises a light source 1 extending along an Archimedean spiral, a lens 2 covering the light source 1, and a reflector 3 for preventing glare. The light-emitting units 11 evenly distributed along the Archimedean spiral make the heat dissipation effect at the center and edge of the light source 1 similar, further improving the overall heat dissipation effect of the lighting assembly 100. At the same time, the reflective body 31 extending along the Archimedean spiral cooperates with the light-emitting units 11 of the light source 1 to achieve refined control of light, thereby obtaining a good lighting effect and further improving the heat dissipation effect. In addition, compared with traditional reflectors, the reflective body 31 extending along the Archimedean spiral is miniature and flat, which effectively reduces the use of heat dissipation materials, thereby reducing costs.

[0077] Therefore, the lamp achieves a good lighting effect by providing the lighting assembly 100 , while also simplifying the structure and reducing the cost of the overall structure.

[0078] The above content is merely an example and illustration of the structure of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these obvious alternative forms are all within the scope of protection of the present invention.
