Description

Anti-glare structure and flexible lamp strip TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible lamp strips, and in particular to an anti-glare structure and a flexible lamp strip. BACKGROUND

[0002] In related technologies, a bare board lamp strip is an important light-emitting component of a lamp strip. In order to protect the bare board lamp strip or to make the light emitted by the bare board lamp strip more uniform, a gel is wrapped around the periphery of the bare board lamp strip to make a flexible lamp strip. The light emitted by the light-emitting surface of the flexible lamp strip illuminates the surrounding environment, and at the same time, the light directly irradiates the eyes of a person to cause discomfort due to 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 lamp strip, the operation of additionally installing a light-transmitting structure is complicated, the production efficiency is low, and the cost is high. In addition, due to process limitations, the light-transmitting structure can only cover a certain length of lamp strip and cannot adapt to different lengths of lamp strip. Furthermore, the light-transmitting structure (including a horizontal and vertical light-shielding plate) will block a large amount of light, resulting in a decrease in light output and insufficient brightness.

[0029] In the related art, the bare board light strip is an important light emitting component of the light bar. In order to protect the bare board light strip or make the light emitted by the bare board light strip more uniform, a gel is wrapped around the periphery of the bare board light strip to make a flexible light strip. The light emitted by the light emitting surface of the flexible light strip illuminates the surrounding environment, and at the same time, the light directly shines into the eyes of people, causing discomfort of glare. At present, there are light transmission structures on the market that can reduce glare by installing a grating plate, an anti-glare plate or a diffusion plate. However, for the flexible light strip, the operation of the additionally installed light transmission structure is complicated, the production efficiency is low and the cost is high. Secondly, due to process limitations, such light transmission structure can only cover a certain length of light strip and cannot adapt to different light strip lengths. Moreover, such light transmission structure (including horizontal and vertical light shielding plates) will block a large amount of light, resulting in a decrease in light output and insufficient brightness.

[0030] To solve the above problems, with reference to Figure 1, in the embodiment of the first aspect of the present application, a glare-proof structure is provided, comprising a lamp body 100, the lamp body 100 comprising a shell 101, the shell 101 comprising an inner cavity 108, the shell 101 having an opening 109 allowing light to exit, a light source being arranged in the inner cavity 108, the light source comprising a lamp bead 103, a circuit board 102 being fixed to the bottom wall of the inner cavity 108, a light-transmitting piece 104 being arranged in the inner cavity 108 and covering the light source, the light-transmitting piece 104 being located on the opening 109, an outer wall 110 of the light-transmitting piece 104 opposite to the light source being provided with a plurality of light-shielding plates 106, a channel 107 for light to exit being formed between two adjacent light-shielding plates 106, and a plurality of channels 107 being arranged along the width direction of the lamp body 100. It can be understood that the light is emitted from the lamp bead 103, transmitted through the light-transmitting piece 104 on the opening 109, and guided by the light-shielding plates 106 to exit from the channels 107 to the outside, thereby achieving the lighting effect. It can be understood that when the light-shielding plates 106 are not arranged, the light scatters in all directions after exiting the light-transmitting piece 104, and the illumination angle is large. When a person views the lamp body 100, the light will directly enter the eyes and cause discomfort. After the light-shielding plates 106 are arranged, the radiation angle of the light can be reduced. When a person views the light-transmitting side of the lamp body 100, the light directly entering the eyes is reduced, thereby achieving the effect of reducing glare. It can be understood that the light-shielding plates 106 can be made of non-light-transmitting material, thereby reducing the angle of the light after exiting the light-transmitting piece 104, and reducing the glare effect. In other embodiments, the light-shielding plates 106 can also be made of light-transmitting material, which can also shield part of the light or change the angle of the light directly entering, thereby achieving the effect of reducing glare.

[0031] Specifically, referring to FIG. 2, the minimum distance between the end of the light shield 106 facing away from the lamp body 100 and the light-transmitting member 104 is defined as H1, and the length of the light shield 106 extending along its axis in the direction away from the lamp body 100 is defined as H2, where H1 = H2, that is, the extension direction of the light shield 106 along its axis is perpendicular to the outer wall 110 of the light-transmitting member 104 (as shown in FIG. 4), and the illumination area is divided into A, B, C and D zones at this time, the A zone is a direct light area with higher brightness, and the width of the A zone is smaller than the maximum width of the light-transmitting member 104; the light emission direction of the B zone has a certain angle, i.e., a first angle, with the emission direction of the A zone, and the size of the first angle can be defined by the height of the light shield 106, the width of the channel 107 and the inclination angle of the light shield 106, the illumination brightness of the B zone is slightly weaker than that of the A zone, and the eye can reduce the glare when directly looking at it; the light emission direction of the C zone has a larger angle, i.e., a second angle, with the emission direction of the A zone, and the size of the second angle can be defined by the height of the light shield 106, the width of the channel 107 and the inclination angle of the light shield 106, the illumination brightness of the C zone is weaker than that of the B zone, and the glare effect can be significantly reduced. The D zone is a non-light area without light emission, and the area of the non-light area increases after the light shield 106 is set. Therefore, after the light shield 106 is set, the direct light range of the light can be effectively reduced, thereby reducing the glare effect when a person directly looks at the light.

[0032] Alternatively, H1 < H2 can be set, that is, the minimum distance between the end of the light shield 106 facing away from the lamp body 100 and the light-transmitting member 104 is smaller than the length of the light shield 106 extending along its axis in the direction away from the lamp body 100, that is, the extension direction of the light shield 106 has an inclination angle with the outer wall 110 of the light-transmitting member 104. Referring to FIG. 2, the inclination angle can be defined as an angle γ, and it can be understood that the angle γ can be set as an acute angle or an obtuse angle not equal to 90°, and the light shields 106 are parallel to each other. At this time, the width of the direct light area A zone of the light is reduced, the light emission direction is changed, and anti-glare areas with different sizes are formed on both sides of the lamp body 100, thereby realizing the control of the size and position of the anti-glare area of the lamp body.

[0033] It can be understood that the plurality of light shielding plates 106 can be parallel to each other, that is, the plurality of light shielding plates 106 can be perpendicular to the outer wall 110 of the light-transmitting piece 104 or keep the same angle γ with the outer wall 110 of the light-transmitting piece 104 along the extension direction away from the lamp body 100, at this time, the cross-sectional shapes of the adjacent two channels 107 are the same, and the light emission range can be uniformly controlled. In other embodiments, referring to FIG. 5, the extension direction of at least two adjacent light shielding plates 106 and the outer wall 110 of the light-transmitting piece 104 have different inclination angles, that is, the plurality of light shielding plates 106 are not parallel to each other along the extension direction away from the lamp body 100, at this time, at least two of the plurality of light shielding plates 106 keep different angles γ with the outer wall 110 of the light-transmitting piece 104, resulting in that the cross-sectional shapes of at least two adjacent channels 107 are different, or the cross-sectional shapes of each channel 107 are different, and the effect of reducing glare can also be achieved.

[0034] Further, the plurality of light shielding plates 106 have the same cross-sectional shape, such as quadrilateral, triangle or trapezoid, and the effect of reducing glare by shielding light and controlling light scattering can also be achieved. In other embodiments, the plurality of light shielding plates 106 have different cross-sectional shapes, so that the cross-sectional shapes of at least two adjacent channels 107 are different, or the cross-sectional shapes of each channel 107 are different.

[0035] Further, the inner cavity 108 is also provided with a reflecting piece 105, which is located on both sides of the light source along the width direction of the lamp body 100. It can be understood that the reflecting piece 105 has a side wall surface inclined to the bottom wall of the inner cavity 108, which is beneficial to increase the effective reflection of light and reduce the reflection times of light, so that more light is incident on the light-transmitting piece 104, thereby achieving the effect of improving light efficiency.

[0036] Referring to FIG. 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 shell 101, the light-transmitting piece 104, the light-shielding plate 106 and the light-reflecting piece 105 are integrally extruded, that is, the length direction of the light-shielding plate 106 is parallel to the length direction of the lamp body 100, and in the process of multi-color extrusion, the shell 101, the light-transmitting piece 104, the light-shielding plate 106 and the light-reflecting piece 105 can be extruded at the same time or gradually extruded through different steps, for example, the shell 101, the light-transmitting piece 104 and the light-reflecting piece 105 are extruded first, and then the light-shielding plate 106 is extruded on the outer wall 110 of the light-transmitting piece 104 through secondary extrusion, without additional installation steps, the production efficiency is effectively improved. Moreover, when the lamp body 100 is formed, the length of the light-shielding plate 106 is consistent with the length of the lamp body 100, the light-shielding plate 106 of any length can be extruded according to different product requirements, the length of the light-shielding plate 106 is not limited, so as to adapt to different product requirements. It can be understood that after the lamp body 100 is extruded, 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 area of the light-emitting region is large, compared with the structure of the assembled grating or honeycomb type anti-dazzle plate (which includes light-blocking plates extending along the length direction and the width direction), the light can be reduced, the light output can be effectively improved during illumination, so as to maintain good illumination effect.

[0037] According to the embodiments of the second aspect of the present application, a flexible lamp strip is provided, comprising the anti-dazzle structure. It can be understood that the flexible lamp strip comprises all the technical features of the anti-dazzle structure, and therefore the flexible lamp strip also has all the beneficial effects of the anti-dazzle structure.

[0038] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
