[0002] In outdoor lighting products, when the light emitted by the product shows the light-sensitive contour of the building at night, in addition to the light landscape design of the product, the overall close-range visual sense of many outdoor lighting modules is very uncomfortable when people approach, causing light pollution. The lighting module cannot adjust the light angle on-site to avoid the discomfort of people at close range, such as glare, or the emission surface of special colors is too wide, resulting in a glare, etc. Colors such as red, blue, and even strongly dazzling wavelengths are further harmful to the human body.

[0003] The utility model with the publication number of CN218820032U discloses a wall lamp, which includes a fixing plate and a lamp installed on the fixing plate. The lamp includes a connecting pipe, a lamp tube, and an LED light strip. A notch corresponding to the length of the LED light strip is opened at the bottom of the lamp tube, and a light-transmitting lamp cover is embedded in the notch. A layer of crystal-like substance is attached to the inner wall surface of the light-transmitting lamp cover and a part of the inner wall surface of the lamp tube. The connecting pipe and the fixing plate are connected by screws and nuts, and the installation angle between the connecting pipe and the fixing plate can be adjusted according to the installation requirements. After the light emitted by the LED light strip is refracted and / or reflected by the crystal-like substance, it is then projected through the light-transmitting lamp cover. This structure is simple, easy to install, the layout of the lamp tube structure has high aesthetic property, and the light is relatively soft and uniform after being refracted by the crystal-like substance and then projected through the light-transmitting lamp cover, so it will not be dazzling, has a strong sense of modernity, meets the aesthetic requirements of young consumers, can also meet the installation angle requirements of customers, has a reasonable structure layout, and improves the product competitiveness.

[0004] The invention with the publication number of CN113090987B discloses an assembled hyperbolic light strip and a construction method at the arc-shaped edge of a floor slab. The invention includes a clamping bracket arranged at the edge of the floor slab and a lamp assembly arranged along the entire length of the edge of the floor slab. The lamp assembly is formed by arranging lamp units in sequence along the edge of the floor slab. The lamp unit is a hyperboloid with a uniform thickness, suspended outside and below the floor slab, and the top is not lower than the floor slab. The top and bottom ends of the lamp unit are respectively connected and fixed to the clamping bracket through connecting components. This invention has high rigidity and has good lighting effects and decorative effects.

[0005] The invention with the publication number of CN114060744A discloses an LED outdoor directional lighting device with a self-anti-glare feature for a partial light beam angle, which includes an LED lamp body and a plurality of LED lenses. The LED lens includes a reflecting cup with an upward opening and a refracting lens arranged at the opening of the reflecting cup. An LED lamp is vertically and upwardly installed at the center of the bottom inside the reflecting cup, and the inner side wall of the reflecting cup is used to reflect the light of the LED lamp to the refracting lens. Among them, the refracting lens includes an inclined surface or a plurality of inclined surfaces arranged side by side. The inclined surface is parallel to the length direction of the LED lamp body and forms an angle with the center line of the LED lamp. Each inclined surface refracts the light reflected onto it to form light rays deviating to the same side of the LED lamp body. This invention has no glare, high luminous uniformity, low cost, simple structure, light weight of the whole lamp, and is easy to assemble.

[0006] In actual use, when an arc-shaped lamp irradiates an arc-shaped surface, it is easy to appear a half-section black shadow on the arc-shaped surface. For specific reference, see Figure 1 , because the arc-shaped surface has an arc curvature, it will change the light path again, resulting in low light utilization rate and a half-section black shadow on the arc-shaped surface.

[0055] An arc-shaped directional polarized light projection arc surface lamp, comprising a light-transmitting lamp cover 101 and a light-emitting strip 102. The inner wall of the light-transmitting lamp cover 101 has a first card slot 103 and a second card slot 104. The first card slot 103 and the second card slot 104 are collinear, and the first card slot 103 and the second card slot 104 are inclined. The light-emitting strip 102 is placed in the light-transmitting lamp cover 101, and both ends of the light-emitting strip 102 are respectively located in the first card slot 103 and the second card slot 104. After the light-emitting strip 102 is fixedly arranged in the light-transmitting lamp cover 101, the light-emitting strip 102 forms an angle of 4-8° with the horizontal plane;

[0056] The lower end of the light-transmitting lamp cover 101 is an arc-shaped structure, which is made of a light-transmitting material. The inner side and the outer side of the arc-shaped structure are an arc-shaped convex surface 105 and an arc-shaped concave surface 106 with different curvature radii.

[0065] The height H3 from the top position of the arc-shaped convex surface 105 to the center of the arc-shaped concave surface 106 is 19.3 ± 2 mm;

[0066] The distance between the highest points of the arc-shaped convex surface 105 and the arc-shaped concave surface 106 is 3.41 ± 2 mm.

[0067] Furthermore, in this embodiment, the radius of curvature of the arc-shaped concave surface 106: R1 = 15.91 mm;

[0068] The radius of curvature of the arc-shaped convex surface 105: R2 = 15.02 mm;

[0069] The centers of the arc-shaped concave surface 106 and the arc-shaped convex surface 105 are located on the center line of the transparent lamp cover 101, and the distance between the center of the arc-shaped concave surface 106 and the center of the arc-shaped convex surface 105 is 4.25 mm;

[0070] The overall width L1 of the arc-shaped convex surface 105 is 18.81 mm;

[0071] The overall width L2 of the arc-shaped concave surface 106 is 15.95 mm;

[0075] The distance between the highest points of the arc-shaped convex surface 105 and the arc-shaped concave surface 106 is 3.41 mm.

[0076] In actual use, the transparent lamp cover 101 is a plastic or flexible material transparent lamp cover, which can adjust the shape of the transparent lamp cover 101 according to the installation environment, making the product flexible and variable. It can be a straight bar structure or a special-shaped structure, and is installed along the fixed back frame by attachment during use, making the operation more convenient.

[0077] The transparent lampshade 101 is made of atomized frosted or transparent material and can be folded into any amplitude or straight strip shape as required. The lampshade is composed of multiple colors or is a semi-fog transparent milky white diffusing lampshade. In actual use, the lampshade has two or more colors.

[0078] In actual use, the light transmittance at the arc-shaped structure is greater than that of the other structures of the transparent lampshade 101.

[0079] The light-emitting strip 102 can be a red light strip, a yellow light strip, a blue light strip, etc. in actual use, and the specific color can be set according to needs. After the light-emitting strip 102 is installed in the transparent lampshade 101, the light-emitting angle of the light-emitting strip 102 is greater than 120°.

Since the two sides of the lens 107 are respectively an arc-shaped convex surface 105 and an arc-shaped concave surface 106, and the curvature radius of the arc-shaped concave surface 106 is greater than that of the arc-shaped convex surface 105, the light is refracted twice when it irradiates the lens 107, realizing the directional polarized light projection of the light onto the arc surface, achieving uniform and shadowless lighting on the arc surface lamp, as Figure 3 shown.

[0081] In actual use, the transparent lampshade 101 is formed by extrusion of optical materials and forms unequal arc surfaces. The arc surface protrusion and the concave surface are non-concentric circular arcs. The arc-shaped protrusion part is an annular body. The orientation of one concave surface and convex surface with the main light path of the light-emitting strip 102 is as follows Figure 4 shown. The annular body of the arc-shaped protrusion part is a convex lens, and a part of the convex surface refracts the light, realizing uniform and shadowless lighting on the arc surface lamp.

[0082] As Figure 5 shown, it is an optical simulation diagram of the lamp projection on the arc surface in the prior art. The optical simulation diagram of the lamp projection on the arc surface described in this application is as Figure 6 shown. According to Figure 5 and Figure 6 shown, the lamp structure shown in this application projects light onto the arc surface and does not form a shadow at the bottom.

Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications that fall within the scope of the present utility model.
