A light-emitting component and a lamp

Abstract

This utility model discloses a light-emitting component and a lamp, including a reflector cup and a biconvex lens. A reflective surface is provided on the inner side of the reflector cup, forming a reflective channel. One end of the reflective channel has a light inlet, and the other end has a light outlet. The biconvex lens is disposed on the reflector cup and covers the light outlet. The biconvex lens has an inner protrusion and an outer protrusion. The inner protrusion faces the reflective channel, and the outer protrusion faces away from the reflective channel. The light-emitting component uses a reflector cup and a biconvex lens. When in use, the biconvex lens can also narrow the range of the secondary light spot, resulting in a more uniform transition between the main and secondary light spots, a clear and rounded outer edge of the light spot, and good overall brightness. Furthermore, the inner protrusion of the biconvex lens faces into the reflective channel, while the outer protrusion faces away from the reflective channel, reducing the outward convexity of the biconvex lens relative to the reflector cup. This makes the structure of the light-emitting component more compact and improves its versatility in assembly.

Description

Technical Field

[0001] This utility model relates to lighting fixtures, and more particularly to a light-emitting component and a lighting fixture. Background Technology

[0002] Some existing lighting fixtures, including light-emitting elements and light-emitting assemblies, use a combination of a reflector and a single convex lens for the light-emitting assembly. The single convex lens covers the light outlet of the reflector, protruding towards the side opposite to the reflector. The light-emitting element is located at the light inlet of the reflector. The single convex lens can narrow the range of the secondary light spot, resulting in a more uniform transition between the main and secondary light spots emitted by the fixture, a clear and rounded outer edge of the light spot, and good overall brightness. However, because the single convex lens protrudes significantly towards the side opposite to the reflector, this type of light-emitting assembly affects the assembly space of other fixture components, making it difficult to match the light-emitting assembly with other parts, thus lacking sufficient universal assemblability.

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.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0035] 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.

[0036] Some existing luminaires emit light from the light-emitting element 300, which is then oriented through a light-emitting element to adjust the light path before being emitted. In some luminaires, the light-emitting element is a reflector 100. The light emitted from the reflector 100 has a clear distinction between the main and secondary light spots, and the secondary light spot is relatively large, resulting in insufficient illumination. In other luminaires, the light-emitting element is a complex optical lens. The light emitted from the optical lens has a relatively uniform transition between the main and secondary light spots and better brightness. However, due to the small cavity between the optical lens and the light-emitting element 300, heat dissipation at the light-emitting element 300 is poor.

[0037] Reference Figures 1 to 8 The light-emitting component of this utility model includes a reflector cup 100 and a biconvex lens 200. A reflective surface 110 is provided on the inner side of the reflector cup 100, forming a reflective channel 120. One end of the reflective channel 120 has a light inlet 130, and the other end has a light outlet 140. The biconvex lens 200 is disposed on the reflector cup 100 and covers the light outlet 140. The biconvex lens 200 has an inner protrusion 210 and an outer protrusion 220. The inner protrusion 210 faces the reflective channel 120, and the outer protrusion 220 faces away from the reflective channel 120.

[0038] The light-emitting assembly uses a reflector cup 100 and a biconvex lens 200. When the light-emitting assembly is in use, the biconvex lens 200 can also narrow the range of the secondary light spot, making the transition between the main and secondary light spots more uniform, the outer edge of the light spot clear and rounded, and the overall brightness of the light spot better. In addition, the inner protrusion 210 of the biconvex lens 200 protrudes into the reflective channel 120, while the outer protrusion 220 protrudes away from the reflective channel 120, which reduces the degree of outward convexity of the biconvex lens 200 relative to the reflector cup 100, thereby making the structure of the light-emitting assembly more compact and improving the versatility of the light-emitting assembly.

[0039] In the embodiments, reference is made to Figure 3 and Figure 7The height of the outer protrusion 220 is greater than the height of the inner protrusion 210. Since the height of the inner protrusion 210 is less than the height of the outer protrusion 220, the height of the biconvex lens 200 protruding into the reflective channel 120 can be reduced, so that the reflector cup 100 has sufficient cavity to supply heat dissipation for the light-emitting element 300, and can reduce interference with the reflective surface 110 of the reflector cup 100.

[0040] In the embodiments, reference is made to Figure 3 and Figure 7 The height of the inner protrusion 210 of the biconvex lens 200 increases with the increase of the diameter of the biconvex lens 200; the height of the outer protrusion 220 of the biconvex lens 200 increases with the increase of the diameter of the biconvex lens 200.

[0041] The light-emitting assembly comes in various sizes. As the diameter of the biconvex lens 200 increases, the height of the inner protrusion 210 and the outer protrusion 220 gradually increases, enabling the biconvex lens 200 to meet the requirements for light refraction. This allows biconvex lenses 200 of different sizes to effectively narrow the secondary light spot, resulting in a more uniform transition between the primary and secondary light spots, a clear and rounded outer edge of the light spot, and good overall brightness.

[0042] In the embodiments, reference is made to Figure 3 and Figure 7 The surface of the biconvex lens 200 is provided with a frosted surface. The frosted surface can make the light passing through the biconvex lens 200 more uniform, reduce the risk of glare for the user, and diffuse the light, reduce contrast, thereby slowing down the progression of myopia.

[0043] In the embodiments, reference is made to Figure 3 and Figure 7 The inner protrusion 210 has a frosted surface, while the outer protrusion 220 has a smooth surface. The frosted surface on the inner protrusion 210 provides better diffuse reflection of light, which helps improve the uniformity of light emitted through the biconvex lens 200.

[0044] Specifically, a frosted surface can be formed through beading or texturing processes.

[0045] It is conceivable that in other embodiments, the outer protrusion 220 of the biconvex lens 200 may be provided with a frosted surface, while the inner protrusion 210 may be provided with a smooth surface; or both the outer protrusion 220 and the inner protrusion 210 may be provided with frosted surfaces. Those skilled in the art can arrange them in a specific manner according to actual needs.

[0046] Preferably, when the light-emitting element 300 emits light in two colors or mixed colors, or when the light spot imaging or light mixing performance is poor, or when there is stray light or dispersion, the biconvex lens 200 is preferably provided with a frosted surface.

[0047] Optionally, the inner protrusion 210 of the biconvex lens 200 can also be provided with protrusions arranged in a Fermat spiral pattern, forming a pattern.

[0048] In the embodiments, reference is made to Figure 3 and Figure 7 The reflective surface 110 of the reflector cup 100 is uneven, which can enhance the light reflection effect, change the light scattering mode and achieve different beam angle effects, thereby improving the lighting effect.

[0049] In the first embodiment, referring to Figure 2 The biconvex lens 200 has a connector block 230 on its outer periphery, and the reflector 100 has a connector slot 150. The connector block 230 and the connector slot 150 are connected and engaged. The biconvex lens 200 and the reflector 100 are positioned by the connector, which ensures a good positioning effect between them. The assembly method is simple and reliable, and the light-emitting components are not prone to relative loosening during use, thus maintaining stable light output quality.

[0050] Specifically, the biconvex lens 200 is provided with a plurality of plug-in blocks 230 around the light outlet 140, and the reflector is provided with the same number of plug-in slots 150 around the light outlet 140 as the plug-in blocks 230. The plug-in blocks 230 and the plug-in slots 150 are plugged in one to one.

[0051] Specifically, when the diameter of the biconvex lens 200 is small, the biconvex lens 200 and the reflector cup 100 can be positioned and connected by a plug-in connection.

[0052] In the second embodiment, refer to Figure 6 The outer periphery of the biconvex lens 200 is snapped into place with the reflector cup 100. The biconvex lens 200 is snapped into the light outlet 140 of the reflector cup 100. The assembly structure between the biconvex lens 200 and the reflector cup 100 is relatively simple and reliable.

[0053] In the second embodiment, refer to Figure 6 The outer periphery of the biconvex lens 200 is provided with an annular mounting part 240, and the reflector cup 100 is provided with an annular groove 160. The annular groove 160 is located around the light outlet 140. The annular mounting part 240 is embedded in the annular groove 160. Three locking blocks 170 are provided on the side wall of the annular groove 160. The locking blocks 170 and the bottom wall of the groove clamp the annular mounting part 240. All the locking blocks 170 are evenly arranged along the outer periphery of the biconvex lens 200.

[0054] When assembling the reflector cup 100 and the biconvex lens 200, the biconvex lens 200 moves toward the annular groove 160. The annular mounting part 240 abuts against the locking block 170, causing a slight elastic deformation of the reflector cup 100. This allows the annular mounting part 240 to pass over the locking block 170 and enter between the locking block 170 and the bottom wall of the annular groove 160. At this time, the locking block 170 and the bottom wall of the annular groove 160 clamp and fix the biconvex lens 200, thus realizing the assembly of the reflector cup 100 and the biconvex lens 200. With the above-described snap-fit ​​structure, the assembly of the biconvex lens 200 and the reflector cup 100 is relatively simple and easy to implement.

[0055] It is conceivable that the number of card blocks could be three or more, and those skilled in the art can choose according to actual needs.

[0056] It is conceivable that the biconvex lens 200 can also be equipped with a hook and a slot in the reflector cup 100, with the hook and slot engaging to achieve assembly and connection between the two.

[0057] It is conceivable that the biconvex lens 200 can also be connected to the reflector cup 100 by means of adhesive or other methods, which is not limited here.

[0058] Specifically, the reflector cup 100 has a process hole on its outer side, which extends to the side wall of the annular groove 160, making it convenient to form the card block 170 located in the annular groove 160.

[0059] This utility model also discloses a lamp fixture that employs the aforementioned light-emitting assembly and light-emitting element 300. The light-emitting element 300 is disposed on one side of the light-emitting assembly, and has a light-emitting side facing the light inlet 130. Due to the adoption of the aforementioned light-emitting assembly, the lamp fixture has a more compact structure and is easier to assemble.

[0060] Specifically, the light-emitting element 300 can be a substrate with LED chips installed, etc. The light emitted by the light-emitting element 300 enters the reflector cup 100 through the light inlet 130. Some of the light is directly emitted through the biconvex lens 200, and some of the light is reflected by the reflective surface 110 on the inner side of the reflector cup 100 and then emitted through the biconvex lens 200.

[0061] Specifically, the luminaire can also have an anti-glare tube installed on one side of the light outlet 140 of the light-emitting component to improve the anti-glare effect of the luminaire. Conventional luminaires have a larger light spot and usually use a shorter anti-glare tube to reduce the impact on the light emission effect. Since the biconvex lens 200 in this embodiment narrows the secondary light spot, that is, the light spot diameter is reduced, the luminaire can be used with a longer anti-glare tube, which has a better anti-glare effect and forms a near-cross-light emission effect.

[0062] Specifically, the reflector cup 100 can be made of high-temperature resistant materials to improve the heat resistance performance of the light-emitting components.
