Technical Field

[0001] The utility model relates to the technical field of flexible light strips, in particular to an anti-glare structure and a flexible light strip. Background Art

[0002] In the related art, a bare board light strip is an important light-emitting component of a light bar. For the protection of the bare board light strip or to make the light emitted by the bare board light strip more uniform, a colloid is wrapped around the periphery of the bare board light strip to make a flexible light strip. When the light emitted from the light-emitting surface of the flexible light strip illuminates the surrounding environment, the light will directly shine into people's eyes and cause the discomfort of glare. At present, there are light-transmitting structures on the market that can reduce glare by installing a grating plate, an anti-glare plate or a diffusion plate. However, for a flexible light strip, the additionally installed light-transmitting structure is cumbersome to operate, has low production efficiency and high cost; secondly, due to process limitations, this light-transmitting structure can only cover a certain length of the light strip and cannot adapt to different light strip lengths; moreover, this light-transmitting structure (including the light-shielding plates in the horizontal and vertical directions) will block a lot of light, resulting in a decrease in the light output and insufficient brightness.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0030] In the related art, the bare board light strip is an important light-emitting component of the light bar. For the protection of the bare board light strip or to make the light emitted by the bare board light strip more uniform, a colloid is wrapped around the periphery of the bare board light strip to make a flexible light strip. While the light emitted from the light-emitting surface of the flexible light strip illuminates the surrounding environment, the light will directly shine into people's eyes and cause the discomfort of glare. At present, there are light-transmitting structures on the market that can reduce glare by installing a grating plate, an anti-glare plate or a diffusion plate. However, for a flexible light strip, the additional installed light-transmitting structure is cumbersome to operate, has low production efficiency and high cost. Secondly, due to process limitations, this light-transmitting structure can only cover a certain length of the light strip and cannot adapt to different light strip lengths. Moreover, this light-transmitting structure (including the lateral and longitudinal light-shielding plates) will block more light, resulting in a reduction in the light output and insufficient brightness.

[0031] To solve the above problems, referring to Figure 1, in the embodiment of the first aspect of the present utility model, a glare-proof structure is provided, which includes a lamp body 100. The lamp body 100 has a housing 101, and the housing 101 has an inner cavity 108. There is an opening on the housing 101 that allows light to emit. A light source is provided in the inner cavity 108. The light source includes a circuit board 102 and lamp beads 103. The circuit board 102 is fixed in the bottom wall of the inner cavity 108. A light-transmitting member 104 covering the light source is provided in the inner cavity 108. The light-transmitting member 104 is located on the opening. A plurality of light-shielding plates 106 are provided on the outer wall of the light-transmitting member 104 facing away from the light source. A channel 107 for emitting light is formed between two adjacent light-shielding plates 106. The plurality of channels 107 are arranged along the width direction of the lamp body 100. It can be understood that light is emitted from the lamp beads 103, passes through the light-transmitting member 104 on the opening, and is emitted to the outside through the channels 107 under the guidance of the light-shielding plates 106 to achieve the lighting effect. It can be understood that when the light-shielding plates 106 are not provided, the light scatters around after leaving the light-transmitting member 104, and the lighting angle is relatively large. When a person looks directly at the lamp body 100, the light will directly shine into the eyes and cause discomfort. After the light-shielding plates 106 are provided, the radiation angle of the light can be reduced. When a person looks at the light-transmitting side of the lamp body 100, the light directly shining into the eyes becomes less, thereby achieving the effect of reducing glare. It can be understood that the light-shielding plates 106 can be made of light-impermeable materials to reduce the angle of the light emitted from the light-transmitting member 104 and thus reduce the glare effect. In some other embodiments, the light-shielding plates 106 can also be made of light-transmitting materials, which can also block part of the light or change the angle of the directly incident light, thereby achieving the effect of reducing the glare effect.

[0032] Specifically, referring to Figure 2 , the minimum distance between the end of the light-shielding plate 106 facing away from the lamp body 100 and the light-transmitting member 104 is defined as H1, and the length of the light-shielding plate 106 extending in the direction away from the lamp body 100 along its axis is H2, where: H1 = H2, that is, the extension direction of the light-shielding plate 106 along its axis is perpendicular to the outer wall surface of the light-transmitting member 104 (as Figure 4As shown in the figure, the lighting area is divided into area A, area B, area C, and area D at this time. Area A is the area directly irradiated by light, with a higher brightness, and the width of area A is less than the maximum width of the light-transmitting member 104; the light-emitting direction of area B has a certain angle with the light-emitting direction of area A, and the size of the angle can be defined by the height of the light-shielding plate 106, the width of the channel 107, and the inclination angle of the light-shielding plate 106. The lighting brightness here is slightly weaker, and the glare can be reduced when viewed directly with the naked eye; the light-emitting direction of area C has a larger angle with the light-emitting direction of area A, and moreover, the size of this angle can be defined by the height of the light-shielding plate 106, the width of the channel 107, and the inclination angle of the light-shielding plate 106. The lighting brightness here is even weaker, and the glare can be significantly reduced. Area D is a lightless area where no light is emitted. After setting the light-shielding plate 106, the area of the lightless area increases. Therefore, after setting the light-shielding plate 106, the direct irradiation range of the light can be effectively reduced, thereby reducing the glare and the dazzling effect when people look directly at the light.

[0033] Furthermore, it can be set that H1 < H2. The minimum distance between the end of the light-shielding plate 106 facing away from the lamp body 100 and the light-transmitting member 104 is less than the length of the light-shielding plate 106 extending along its axis in the direction away from the lamp body 100, that is, there is an inclination angle between the extending direction of the light-shielding plate 106 and the outer wall of the light-transmitting member 104. Refer to Figure 2 , the inclination angle can be defined as the included angle γ. It can be understood that the included angle γ can be set as an acute angle or an obtuse angle not equal to 90°. At this time, the width of the direct irradiation area A of the light becomes smaller, and the light-emitting direction is changed, forming anti-glare areas with different sizes on both sides of the lamp body 100, so as to control the size and position of the anti-glare area of the lamp body.

[0034] It can be understood that several light-shielding plates 106 can be parallel to each other, that is, multiple light-shielding plates 106 can be perpendicular to the outer wall of the light-transmitting member 104 or maintain the same included angle γ with the outer wall of the light-transmitting member 104 along the extending direction away from the lamp body 100. At this time, the cross-sectional shapes of adjacent two channels 107 are the same, and the light-emitting range can be uniformly controlled. In some other embodiments, refer to Figure 5 , there are different inclination angles between the extending directions of adjacent two light-shielding plates 106 and the outer wall of the light-transmitting member 104, that is, several light-shielding plates 106 are not parallel to each other along the extending direction away from the lamp body 100. At this time, multiple light-shielding plates 106 maintain different included angles γ with the outer wall of the light-transmitting member 104, resulting in different cross-sectional shapes of adjacent two channels 107, or different cross-sectional shapes of each channel 107, and the effect of reducing glare can also be achieved.

[0035] Furthermore, several light-shielding plates 106 have the same cross-sectional shape, such as quadrilateral, triangular, or trapezoidal, etc., and can also achieve the functions of light shielding, controlling light scattering, and reducing the glare effect. In some other embodiments, several light-shielding plates 106 have different cross-sectional shapes, and at the same time, the cross-sectional shapes of two adjacent channels 107 are different, or the cross-sectional shapes of each channel 107 are all different.

[0036] Furthermore, a reflector 105 is also provided in the inner cavity 108. Along the width direction of the lamp body 100, the reflector 105 is located on both sides of the light source. It can be understood that the reflector 105 has a side wall surface inclined to the bottom wall of the inner cavity 108, which is beneficial to increasing the effective reflection of light, reducing the number of light reflections, and allowing more light to be incident on the light-transmitting member 104, thereby achieving the effect of improving the light efficiency.

[0037] Referring to Figure 3 , it can be understood that the length direction of the channel 107 is parallel to the length direction of the lamp body 100. The housing 101, the light-transmitting member 104, the light-shielding plate 106, and the reflector 105 are integrally extrusion-molded, that is, the length direction of the light-shielding plate 106 is parallel to the length direction of the lamp body 100. During the multi-color extrusion molding process, the housing 101, the light-transmitting member 104, the light-shielding plate 106, and the reflector 105 can be simultaneously extruded and molded, or gradually extrusion-molded through multiple different steps. For example, first extrude the housing 101, the light-transmitting member 104, and the reflector 105, and then through secondary extrusion, the light-shielding plate 106 is extrusion-molded on the outer wall of the light-transmitting member 104, without additional installation steps, effectively improving the production efficiency. Moreover, when the lamp body 100 is molded, the length of the light-shielding plate 106 is consistent with the length of the lamp body 100, and any length can be extruded according to different product requirements. The length of the light-shielding plate 106 is not restricted, so as to be able to adapt to different product requirements. It can be understood that after the lamp body 100 is extrusion-molded, the channel 107 extends along the length direction of the lamp body 100, and the channel 107 penetrates along the length direction of the lamp body 100. The light-emitting area is relatively large. Compared with the current structure of assembling a grating or a honeycomb anti-glare plate (which includes light-shielding plates extending along the length and width directions), it can reduce the light shielding, effectively improve the light output during lighting, and thus maintain a good lighting effect.

[0038] According to an embodiment of the second aspect of the present invention, a flexible light strip is provided, including the above anti-glare structure. It can be understood that the flexible light strip includes all the technical features of an anti-glare structure, so the flexible light strip also has all the beneficial effects of an anti-glare structure.

[0039] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant art.
