Description

Technical Field

[0001] This utility model patent relates to the technical field of low-glare lenses, and specifically to a low-glare lamp with a small hole light output. Background Art

[0002] TIR lenses are widely used in commercial lighting due to their high luminous efficiency, uniform light spot, and simple optical path. However, there are some problems with TIR lenses. When looking directly into a lamp with a TIR lens, the light is very dazzling. This dazzling light is called glare. Glare is a major cause of visual fatigue and is a common problem.

[0003] The light from the TIR lens is mainly divided into two parts, one is the side reflected light, and the other is the middle refracted light. Since the optical path of the middle refracted light is short and not as divergent as the side reflected light, the glare problem of the middle direct light is the most serious.

[0004] For example, the prior patent with authorization announcement number CN220601307U discloses a physical anti-glare lens, comprising a lens body (1), wherein a bottom groove (11) is provided at the bottom of the lens body (1), the inner wall of the bottom groove (11) is a first reflection surface (12), and the top of the bottom groove (11) is a convex lens structure, the periphery of the lens body (1) is a total reflection surface (13), and the upper surface of the lens body (1) is provided with a plurality of surface dots (14) for light diffuse scattering, characterized in that it also comprises: a one-piece bracket (2), wherein the one-piece bracket (2) is sleeved on the outside of the lens body (1) and is used to support the lens body (1); an LED light source (3), wherein the LED light source (3) is installed at an opening opened at the center bottom of the one-piece bracket (2); and a plug (4), wherein a groove (17) is provided at the center of the surface of the lens body (1), and the plug (4) is installed at the groove (17), and the plug (4) is used to block part of the light source.

[0005] In the prior art, the intermediate refracted light of the TIR lens is shielded to achieve low glare of the TIR lens. However, shielding the light will reduce the light efficiency of the lens, resulting in poor light efficiency of the TIR lens. Utility Model Content

[0006] The purpose of the utility model is to provide a low-glare lamp with a small hole light output, aiming to solve the problem of poor light efficiency of low-glare lenses in the prior art.

[0007] The present invention is achieved in this way: a low-glare lamp with a small hole light output type includes a bracket, a lens body, a mesh cup member and a front cover member, the lens body is located inside the bracket, and the lens body and the bracket are assembled, and the mesh cup member and the front cover member are assembled; the mesh cup member has a draft portion, and the front cover member has a small hole portion, along the direction away from the lens body, the draft portion and the small hole portion are arranged to correspond to and be connected, and the diameter of the draft portion is arranged to gradually increase, and the diameter of the small hole portion is smaller than the diameter of the draft portion, and the light emitted by the light source is projected outward through the lens body, the draft portion and the small hole portion in sequence.

[0008] Furthermore, the draft portion has a draft surface, which is arranged in a direction away from the lens body, and the draft surface is arranged corresponding to the light-emitting surface of the lens body. The small hole portion has an inner hole surface close to the draft portion, and the inner hole surface is arranged to overlap with the draft surface, and the inner hole surface is used to allow light to pass through.

[0009] Furthermore, the diameters of the small holes are arranged to gradually increase in a direction away from the inner hole surface.

[0010] Furthermore, the lens body has a light-emitting surface, the demolding portion has a die-entry surface, the light-emitting surface, the die-entry surface and the inner hole surface are arranged in sequence, and the center of the light-emitting surface, the center of the die-entry surface and the center of the inner hole surface are arranged opposite each other along a straight line.

[0011] Furthermore, the cross-sectional area of the light-emitting surface is smaller than the cross-sectional area of the die-entry surface, and the cross-sectional area of the die-entry surface is larger than the cross-sectional area of the inner hole surface.

[0012] Furthermore, the mesh cup member includes a mirror ring portion, which is used for embedding the end portion of the lens body. The lens body has a light-emitting surface, and the light-emitting surface is arranged inside the mirror ring portion.

[0013] Furthermore, the mirror ring portion forms a mirror ring surface, and the mirror ring surface is arranged to overlap with the draft surface, and light enters the draft portion through the light emitting surface and the draft surface in sequence.

[0017] Compared with the prior art, the present invention provides a low-glare lamp with a small hole light output. When in use, the light emitted by the light source passes through the lens body, the draft part and the small hole part and is projected outward. Under the action of the small hole part, most of the scattered glare is blocked. At the same time, the small hole part allows the cross light from the side and the parallel light in the middle to pass through, forming a uniform light spot with cross light as the main part and parallel light as the auxiliary part, increasing the number of small holes for light output and maximizing the light effect of the small hole light output. In addition, the draft part adjusts the light path of the glare originally reflected from the side wall of the lamp and limits the diffusion angle of the light beam. Under the coordinated action of the draft part and the small hole part, not only the diffusion angle of the light beam is limited, but also the refracted light in the middle of the lens body is converged, and the refracted light with more severe deflection is blocked by the small hole, forming a low-glare spot with reflected light as the main part and parallel light as the auxiliary part, thereby reducing the discomfort caused by glare and achieving low glare.

[0028] Reference Figure 1-7 The figure shows a preferred embodiment of the present invention.

[0029] A pinhole-light-emitting low-glare lamp comprises a bracket 1, a lens body 2, a mesh cup 3 and a front cover 4. The lens body 2 is located inside the bracket 1, and the lens body 2 and the bracket 1 are assembled, and the mesh cup 3 and the front cover 4 are assembled; the mesh cup 3 has a draft portion 31, and the front cover 4 has a small hole portion 41. Along the direction away from the lens body 2, the draft portion 31 and the small hole portion 41 are arranged to correspond to and be connected, and the diameter of the draft portion 31 is arranged to gradually increase, and the diameter of the small hole portion 41 is smaller than the diameter of the draft portion 31. Light emitted by the light source is projected outward through the lens body 2, the draft portion 31 and the small hole portion 41 in sequence.

[0030] When the above-mentioned low-glare lamp with small hole light output is in use, the light source emits light and is projected outward after passing through the lens body 2, the draft portion 31 and the small hole portion 41. Under the action of the small hole portion 41, most of the scattered glare is blocked. At the same time, the small hole portion 41 allows the cross light from the side and the parallel light in the middle to pass through, forming a uniform light spot with cross light as the main component and parallel light as the auxiliary component, thereby increasing the number of small holes for light output and maximizing the light effect of the small hole light output. In addition, the draft portion 31 adjusts the light path of the glare originally reflected from the side wall of the lamp and limits the diffusion angle of the light beam. Under the coordinated action of the draft portion 31 and the small hole portion 41, not only the diffusion angle of the light beam is limited, but the refracted light in the middle of the lens body 2 is converged, and the refracted light with more severe deflection is blocked by the small hole, forming a low-glare light spot with reflected light as the main component and parallel light as the auxiliary component, thereby reducing the discomfort caused by glare and achieving low glare.

[0031] The draft portion 31 has a draft surface 32, which is arranged in a direction away from the lens body 2. The draft surface 32 is arranged corresponding to the light-emitting surface of the lens body 2. The small hole portion 41 has an inner hole surface 42 close to the draft portion 31, and the inner hole surface 42 is arranged to overlap with the draft surface 32. The inner hole surface 42 is used to allow light to pass through.

[0032] In this way, the light enters the small hole portion 41 through the draft portion 31, and the draft surface 32 adjusts the optical path of the glare originally reflected from the side wall of the lamp, so that the light can only diffuse outward through the inner hole surface 42. The diffusion angle of the light beam is limited by the inner hole surface 42, forming a low-glare spot with reflected light as the main part and parallel light as the auxiliary part, thereby reducing the discomfort caused by glare and achieving low glare.

[0033] The aperture of the small hole portion 41 is arranged to gradually increase in the direction away from the inner hole surface 42; the light passing through the inner hole surface 42 is guided by the small hole portion 41, which facilitates the formation of a light spot. At the same time, the number of lights exiting the small hole portion 41 is increased, and the light effect of the off-track light of the small hole portion 41 is maximized.

[0034] The lens body 2 has a light-emitting surface, and the draft portion 31 has a die-entry surface 33. The light-emitting surface, the die-entry surface 33 and the inner hole surface 42 are arranged in sequence, and the center of the light-emitting surface, the center of the die-entry surface 33 and the center of the inner hole surface 42 are arranged opposite each other along a straight line; in this way, the light spot formed is more uniform and the light controllability is stronger.

[0035] The cross-sectional area of the light-emitting surface is smaller than the cross-sectional area of the die-entry surface 33 , so that all light passing through the light-emitting surface can enter the die-entry surface 33 , thereby ensuring the light efficiency.

[0036] The cross-sectional area of the die surface 33 is larger than the cross-sectional area of the inner hole surface 42; the inner hole surface 42 limits the diffusion angle of the light beam, forming a low-glare spot with reflected light as the main component and parallel light as the auxiliary component, thereby reducing the discomfort caused by glare and achieving low glare.

[0037] The mesh cup member 3 includes a lens ring portion, and the lens ring portion is used for embedding and arranging the end portion of the lens body 2 to achieve assembly of the lens body 2 and the mesh cup member 3 .

[0038] The lens body 2 has a light emitting surface, which is arranged inside the mirror ring portion; the mirror ring portion prevents light leakage and facilitates light to enter the mesh cup 3 through the lens body 2.

[0039] The mirror ring portion forms a mirror ring surface, which is arranged to overlap with the draft surface 32 , and light enters the draft portion 31 through the light-emitting surface and the draft surface 32 in sequence, facilitating the entry of light.

[0040] The bracket 1 includes a mirror frame portion 11 and a lamp frame portion 12. The mirror frame portion 11 and the lamp frame portion 12 are assembled. The lamp frame portion 12 is used to assemble the light source to realize the assembly and fixation of the light source. The mirror frame portion 11 is used to assemble the lens body 2 to realize the assembly and fixation of the lens body 2. The mirror frame portion 11 is embedded with a mirror ring portion to effectively avoid light leakage and ensure light efficiency.

[0041] The net cup member 3 includes a net ring portion, the draft portion 31 and the net ring portion are butted against each other, and the net ring portion is used for embedding the front cover member 4 , thereby improving the assembly effect of the net cup member 3 and the front cover member 4 .

[0042] The mesh cup member 3 and the front cover member 4 are integrally formed, which is convenient for production and assembly; the small hole portion 41 extends to the outside of the mesh cup member 3, maximizing the light effect of the small hole light output, and at the same time limiting the diffusion angle of the light beam, forming a low-glare spot with reflected light as the main component and parallel light as the auxiliary component, thereby reducing the discomfort caused by glare and achieving low glare.

[0043] The pinhole-light low-glare lamps include a variety of different specifications. For details, please see the attached manual. Figure 2-4 .

[0044] Compared with traditional lamps, the low-glare lamp with a small hole light output provided by the present application has a significantly reduced UGR (glare index).

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
