Description

Technical Field

[0001] This utility model belongs to the field of LED lens technology, specifically relating to a wide-angle wall washer corridor light lens and lamp. Background Technology

[0002] An LED lens is an optical system used in conjunction with LEDs. Its core function is to adjust the light field distribution of the light source, improve luminous efficiency and focusing performance, and it is widely used in automotive lighting, electronic equipment and commercial lighting.

[0003] LED lenses are used in wall washer lights to illuminate walls, allowing the light to wash over the wall like water. They are commonly used to illuminate interior walls or building facades. Currently, wall washer lenses typically require an array of strip or textured structures on the light-emitting surface to deflect the light and achieve the wall-washing effect. However, current structures can only deflect the light in a specific direction and cannot achieve lateral illumination. In scenarios requiring wide-angle lighting adjustment, such as corridors, the illuminance range of conventional LED wall washer lenses cannot meet the needs. Utility Model Content

[0004] To address the shortcomings of existing technologies, a wide-angle wall washer corridor light lens and fixture are provided to solve the problem that conventional wall washer lights do not provide sufficient illumination range.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wide-angle wall washer lens, comprising: The light-incident structure has a bottom surface that is the light-incident surface. A light-emitting structure is disposed on top of the light-incident structure. The top of the light-emitting structure is provided with a conical light-emitting surface to emit light through the conical light-emitting surface to the center of the target area. The top of the light-emitting structure is located on both sides of the conical light-emitting surface, and two arc-shaped light-emitting surfaces are symmetrically arranged along the first direction to emit light through the arc-shaped light-emitting surfaces to both sides of the target area.

[0006] Compared with existing technologies, the above technical solutions have the following beneficial effects: The cone-shaped light-emitting surface at the top center diffuses and homogenizes the excess light directly from the light source structure, illuminating the center of the target area. The arc-shaped light-emitting surfaces on both sides refract the light to diffuse to both sides, creating a wall-washing effect on both sides of the target area, thus meeting the usage requirements.

[0007] Based on the above technical solution, the embodiments of this application can be further improved as follows: In one embodiment, the conical light-emitting surface is a strip-shaped conical light-emitting surface extending along a second direction perpendicular to the first direction, and the two arc-shaped light-emitting surfaces are symmetrically arranged on both sides of the strip-shaped conical light-emitting surface.

[0008] By setting the light-emitting surface in this way, the light emitted to the central area can be formed into a long strip of light along the first direction, which is suitable for use in passageways.

[0009] In one embodiment, the light-incident structure is a frustum-shaped structure with its top end tapering inwards, and the frustum-shaped structure is used to inwardly refract light rays to the arc-shaped light-exiting surface.

[0010] In one embodiment, at least two conical light-emitting surfaces are symmetrically arranged along a first direction, and the total width of the two conical light-emitting surfaces corresponds to the width of the top of the light-incident structure. The conical light-emitting surfaces are used to emit light rays passing through the interior of the light-incident structure.

[0011] In one embodiment, the conical light-emitting surface and the arc-shaped light-emitting surface are sequentially provided with arc-shaped stripes along the second direction, and the arc-shaped stripes are used to deflect and diffuse the light towards both sides along the first direction.

[0012] In one embodiment, the spacing between the arc-shaped stripes is 1.0 mm ± 0.1 mm, and the R value of the arc-shaped stripes is 0.8-1.0 mm [1].

[0013] In one embodiment, the top periphery of the light-emitting structure is provided with a stepped edge that surrounds the conical light-emitting surface and the arc-shaped light-emitting surface, and the stepped edge is provided with a textured surface.

[0014] In one embodiment, the light-receiving surface is provided with a textured surface.

[0015] In one embodiment, the step is provided with buckles or slots at intervals along its upper circumferential direction.

[0016] This embodiment also discloses a lighting fixture, which includes the wide-angle wall washer lens as described above. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Example 1 like Figure 1-4 As shown, the wide-angle wall washer lens provided by this utility model includes: light-incident structure 1 and light-outcident structure 2, which are integrally formed.

[0028] The bottom surface of the light-incident structure 1 is the light-incident surface 9. Setting the entire bottom surface of the light-incident structure 1 as the light-incident surface 9 increases the amount of light entering the light-incident surface 9. The light-exiting structure 2 is located on top of the light-incident structure 1. A conical light-exiting surface 3 is convexly arranged on the top of the light-exiting structure 2. The conical light-exiting surface 3 is located on top of the light-exiting structure 2 to direct the light passing through the conical light-exiting surface 3 to the center of the target area. In operation, the center of the target area is illuminated in the aisle. Two arc-shaped light-exiting surfaces 4 are symmetrically arranged on both sides of the conical light-exiting surface 3 at the top of the light-exiting structure 2, along a first direction, to direct the light passing through the arc-shaped light-exiting surfaces 4 to both sides of the target area. Specifically, the arc-shaped light-exiting surfaces 4 are convex arc-shaped light-exiting surfaces 4, allowing the light passing through these surfaces to deflect and diffuse to both sides. The two sides of the target area are illuminated on the walls or shelves on both sides of the aisle. The first direction is the direction along the interval between the two arc-shaped light-exiting surfaces 4. Figure 3 The horizontal direction in the middle.

[0029] The cone-shaped light-emitting surface 3 at the top center can diffuse and homogenize the excessive light emitted directly from the light-incident structure 1, illuminating the center of the target area. The arc-shaped light-emitting surfaces 4 on both sides refract the light to diffuse to both sides, illuminating both sides of the target area to form a wall-washing effect, thereby meeting the usage requirements.

[0030] In one embodiment, the conical light-emitting surface 3 is a strip-shaped conical light-emitting surface 3 extending along a second direction perpendicular to the first direction. Two arc-shaped light-emitting surfaces 4 are symmetrically arranged on both sides of the strip-shaped conical light-emitting surface 3. The second direction is a horizontal direction perpendicular to the first direction. Figure 4 In the horizontal direction, by specifically setting the conical light-emitting surface 3 as a conical strip, with the strip extending in the second direction, the light emitted to the central area can form a long strip of light spot along the first direction, which can be adapted to the passageway.

[0031] like Figure 3 As shown, to improve light utilization, the light-incident structure 1 is a frustum-shaped structure with its top end tapering inward. The frustum-shaped structure is used to inwardly refract light to the arc-shaped light-emitting surface 4. Compared with the bowl-shaped refraction structure, the frustum-shaped structure can better collect light, thereby improving light utilization. Since the bottom surface of the light-incident structure 1 is the entire light-incident surface 9, the frustum-shaped structure enhances the inward tapering effect, ensuring that all light can enter the light-emitting structure 2 and diffuse to both sides through the arc-shaped light-emitting surface 4, ensuring that the light enters the light-emitting surface and diffuses to both sides to achieve the lighting effect. The top surface of the frustum structure is smaller than the top surface of the light-emitting structure 2. Specifically, the top of the frustum structure and the bottom center of the light-emitting structure 2 are integrally formed. Light rays refracted from the side of the frustum structure first enter the bottom of the light-emitting structure 2. At this time, the bottom of the light-emitting structure 2 is a convex bowl-shaped structure, which can gather the incoming light rays to the light-emitting surface. Then, the light rays are deflected and diffused to both sides through the arc-shaped light-emitting surfaces 4 on both sides of the top of the light-emitting structure 2. The light rays passing through the top of the frustum structure directly enter the light-emitting structure 2 and are then homogenized and emitted through the conical light-emitting surface 3 at the top center of the light-emitting structure 2.

[0032] In this embodiment, at least two conical light-emitting surfaces 3 are symmetrically arranged along the first direction. Having two protruding conical light-emitting surfaces 3 allows for better uniformity of light emitted from these surfaces. The total width of the two conical light-emitting surfaces 3 corresponds to the width of the top of the light-incident structure 1. Specifically, as shown... Figure 3 As shown, the total width of the conical light-emitting surface 3 is W, and the corresponding width of the top of the light-incident structure 1 is w. The width w is basically consistent with the width W, so that the conical light-emitting surface 3 can be used to emit light rays passing through the interior of the light-incident structure 1, so that the excess light emitted from the central region entering from the light-incident structure 1 can be diffused by the two conical light-emitting surfaces 3, resulting in a uniform central illumination effect.

[0033] like Figure 4 As shown, the conical light-emitting surface 3 and the arc-shaped light-emitting surface 4 are sequentially provided with arc-shaped stripes 5 along the second direction. The arc-shaped stripes 5 are used to deflect and diffuse the light to both sides along the first direction. The flatly arranged arc-shaped stripes 5 can not only homogenize and diffuse the light, but also make the light diffuse along the second direction, thereby achieving a superimposed and coordinated effect with the diffused light of the next lamp.

[0034] Specifically, the spacing of the arc-shaped stripes 5 is 1.0mm ± 0.1mm, and the R value of the arc-shaped stripes 5 is 0.8-1.0mm[2].

[0035] The top periphery of the light-emitting structure 2 is provided with a stepped edge 6 that surrounds the conical light-emitting surface 3 and the arc-shaped light-emitting surface 4. The stepped edge 6 is provided with a textured surface, which can evenly distribute a small portion of the light emitted through the surface.

[0036] In this embodiment, the light-incident surface 9 is provided with a textured surface to uniformly allow light to enter the light-incident structure 1.

[0037] To facilitate direct assembly, the step 6 is provided with buckles 7 or slots 8 at intervals along its circumference, which can be used to directly install and fix the lens to the external lamp cover or other structures.

[0038] Example 2 This embodiment also discloses a lamp that includes a wide-angle wall washer lens as described in Embodiment 1 above.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
