Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, specifically relating to a lens and a lighting fixture equipped with the lens. Background Technology

[0002] Existing lighting equipment, such as shelf lights, often suffers from insufficient beam angles in their lens designs. The light emitted from the lamp source, after passing through the lens, can only cover a relatively small area, failing to achieve wide-area, uniform illumination. Due to the limited illumination range of existing lenses, a large number of lamps are often required to achieve the desired lighting effect. This not only increases the procurement cost of the lamps but also makes the installation work complex and cumbersome, requiring more manpower, resources, and time for installation and wiring.

[0003] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0005] A lens, used in conjunction with a light source, includes a connecting part and lens parts disposed on both sides of the connecting part. The lens parts are located within the illumination range defined by the beam angle of the light source. The inner surface of the lens part facing the light source is concave, and the outer surface facing the external environment is convex. This structural design effectively utilizes the light emitted by the light source. Through the combined action of the two sets of lens parts, it expands the illumination range, overcomes the problem of insufficient beam angle in existing products, meets the application needs of shelf lights and other applications requiring large-area illumination, reduces the number of light fixtures required to a certain extent, achieves the lighting effect of two light fixtures with one fixture, and reduces costs and installation complexity.

[0006] In a preferred embodiment, the concave surface is generally V-shaped. This shape facilitates the convergence and reflection of light emitted from the lamp source, guiding the light to the outer surface of the lens at a specific angle and direction, increasing the light emission angle, further expanding the beam angle, and enabling the light to cover a wider area.

[0007] In a preferred embodiment, the concave surface has a rounded corner transition at the bottom of the generally V-shaped area. This design avoids excessive refraction or reflection of light at the sharp bottom of the V-shape, reducing light energy loss and uneven light spots.

[0008] In a preferred embodiment, the convex surface is generally arc-shaped. This shape allows light refracted from the inner surface to be refracted and diffused again, resulting in a more even distribution of light into the external environment, avoiding obvious uneven areas of light and shadow, and making the lighting effect more uniform and softer.

[0009] In a preferred embodiment, both the inner surface of the connecting portion facing the light source and the outer surface facing the external environment are planar. A planar surface can uniformly reflect and refract light, avoiding uneven light spots caused by changes in surface curvature, and preventing the central area from being darker than the sides within the defined illumination range of the beam angle.

[0010] A lighting fixture includes a housing and the aforementioned lens. The lens has a snap-fit ​​mechanism, and the housing has a groove for engaging the snap-fit. This snap-fit ​​and groove mechanism makes the installation and removal of the lens from the housing convenient and quick, requiring no additional complex tools or cumbersome procedures, thus improving assembly efficiency and reducing production costs and maintenance difficulty.

[0011] In a preferred embodiment, the latch is located on the upper surface of the lens portion away from the connecting portion. Symmetrically arranged latches enhance the connection strength between the lens and the housing, ensuring that the lens will not easily loosen or fall off during use, thus improving the reliability and safety of the luminaire.

[0012] In a preferred embodiment, the lateral surface of the lens portion away from the connecting portion is flush with the side surface of the housing. This makes the overall appearance of the lamp more concise and aesthetically pleasing.

[0013] Compared with the prior art, this application has the following beneficial technical effects: through the combined action of the two lens parts, the illumination range of the light is expanded, realizing large-angle lighting applications, reducing the number of lamps used to a certain extent, and reducing costs and installation complexity.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] In the following embodiments, the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] refer to Figures 1 to 3 A lens 10, used in conjunction with a light source, includes a connecting portion 11 and lens portions 12 disposed on both sides of the connecting portion 11. The lens portions 12 are located within the illumination range defined by the beam angle of the light source. The inner surface of the lens portion 12 facing the light source is concave 13, and the outer surface facing the external environment is convex 14. This structural design effectively utilizes the light emitted by the light source. Through the combined action of the two sets of lens portions 12, the illumination range of the light is expanded, overcoming the problem of insufficient beam angle in existing products. This meets the application requirements of shelf lights and other applications requiring large-area illumination, and to a certain extent reduces the number of light fixtures used, achieving the advantage of one light fixture achieving the lighting effect of two light fixtures, thus reducing costs and installation complexity.

[0026] Furthermore, the concave surface 13 is approximately V-shaped. This shape facilitates the convergence and reflection of light emitted from the lamp source, guiding the light at a specific angle and direction to the outer surface of the lens portion 12, increasing the light emission angle, further expanding the beam angle, and enabling the light to cover a wider area. The bottom of the V-shape is rounded. This design avoids excessive refraction or reflection concentration of light at the sharp bottom of the V-shape, reducing light energy loss and uneven light spots. The convex surface 14 is approximately arc-shaped. This shape allows for further refraction and diffusion of light refracted from the inner surface, resulting in a more even distribution of light in the external environment, avoiding obvious uneven areas of light and shadow, and making the lighting effect more uniform and softer.

[0027] In this application, both the inner surface of the connecting part 11 facing the light source and the outer surface facing the external environment are planar. A planar surface can uniformly reflect and refract light, avoiding uneven light spots caused by changes in surface curvature, and preventing the central area from being darker than the sides within the illumination range determined by the beam angle.

[0028] As another embodiment, this application proposes a lamp, with reference to Figure 4 and Figure 5 The assembly includes a housing 20 and a lens 10. The lens 10 is provided with a buckle 15, and the housing 20 is provided with a groove 21 that mates with the buckle 15. This mating structure of the buckle 15 and the groove 21 makes the installation and removal of the lens 10 and the housing 20 convenient and quick, without the need for additional complicated tools and cumbersome procedures, thereby improving assembly efficiency and reducing production costs and maintenance difficulty.

[0029] Furthermore, the latch 15 is located on the upper surface 16 of the lens portion 12 on the side away from the connecting portion 11. The symmetrically arranged latches 15 enhance the connection strength between the lens 10 and the housing 20, ensuring that the lens 10 will not easily loosen or fall off during use, thus improving the reliability and safety of the luminaire. The lateral surface 17 of the lens portion 12 on the side away from the connecting portion 11 is flush with the side surface 22 of the housing 20, making the overall appearance of the luminaire simpler and more aesthetically pleasing.
