In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0032] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0033] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0034] Reference Figure 1-3 The present invention provides an anti-glare LED light trough, which is used to alleviate the direct light from hitting the human eyes and improve the comfort of use. The LED light trough includes a lamp body 1, a lampshade 2 and an LED light source 3. The lampshade 2 is fixed inside the lamp body 1, and the lampshade 2 and the lamp body 1 are combined to form a receiving groove. The LED light source 3 is fixed in the receiving groove. The light emitting direction of the LED light source 3 is toward the lampshade 2. When emitting light, the light can be transmitted from the lampshade 2.

[0035] The lamp body 1 includes a frame-shaped lamp body 1 made of aluminum alloy, and the lamp body 1 includes a closed side 11 and an open side 12 arranged opposite to each other, and the lampshade 2 enters and is fixed in the lamp body 1 through the open side 12. The lamp body 1 has two sides provided with card slots 13, and the card slots 13 can facilitate the card connection and fixing of the lampshade 2 in the lamp body 1. The lamp body 1 made of aluminum alloy has good heat dissipation effect and strength, and can improve the working stability and structural strength of the LED light trough.

[0036] The lampshade 2 includes a lens portion 21 and a reflective portion 22, and the lens portion 21 and the reflective portion 22 are integrally formed PC material lampshades 2. The PC material lampshade 2 can provide a better light transmission effect. Two reflective portions 22 are provided, and the two reflective portions 22 are respectively fixed to the lens portion 21. The two reflective portions 22 are symmetrically arranged relative to the middle of the lampshade 2, and the side of the two reflective portions 22 away from the lens portion 21 is connected to the inside of the lamp body 1, so that the lens portion 21 is mounted and fixed inside the lamp body 1.

[0037] The lens includes a first surface 211 and a second surface 212 that are arranged opposite to each other. The first surface 211 is arranged close to the LED light source 3. The first surface 211 is a concave surface, and the second surface 212 is a convex surface. In the prior art, the light-emitting surface of the lampshade 2 is a plane mirror. The light emitted by the LED light source 3 directly enters the human eye, which is serious and easy to cause glare. However, the lens portion 21 of the present application is a convex mirror. The light emitted by the LED light source 3 is transmitted to the first surface 211. Under the refraction of the first surface 211 and the second surface 212, the light emitted by the LED light source 3 will not be emitted directly, but will be emitted toward both sides of the inside of the lamp body 1, hiding the direct strong light inside the lamp body 1. The light reaches the human eye from the side through one reflection, achieving the effect of having brightness but not being able to directly see the strong light, so that the human eye cannot see the light source of the lamp within a certain angle range, achieving the anti-glare effect, and protecting the human eye.

[0038] When the lampshade 2 is fixed to the lamp body 1, the reflective portion 22 is located on the side of the lens portion 21 away from the LED light source 3, and the two reflective portions 22 are arranged obliquely, and the side of the reflective portion 22 away from the lens portion 21 tends to be inclined in a direction away from each other. Through this structural setting, it is possible to prevent the light emitted from the lens portion 21 from being directly transmitted to the lamp body 1, and the lamp body 1 made of aluminum alloy will absorb part of the light, resulting in energy waste. The light emitted from the lens portion 21 can be incident on the reflective portion 22, and the reflectivity can be improved by passing through the reflective portion 22, so that the light energy can be used efficiently.

[0039] As an embodiment, the two reflective parts 22 are both fixed with a first clamping protrusion 221 on the side away from each other, and the first clamping protrusion 221 can be clamped in the clamping groove 13. When fixing the lampshade 2, the elasticity of the materials of the lampshade 2 and the lamp body 1 can be used to push the lampshade 2 from the opening side 12, and the first clamping protrusion 221 is clamped in the clamping groove 13, so as to fix the lampshade 2. Further, the lamp body 1 is provided with a strip groove 14 at the position corresponding to the opening side 12, and the side of the reflective part 22 away from the lens part 21 is provided with a second clamping protrusion 222, and the second clamping protrusion 222 can be placed in the strip groove 14, and the side wall of the second clamping protrusion 222 abuts against the strip groove 14. The cooperation between the second clamping protrusion 222 and the strip groove 14 can improve the stability of the connection between the lampshade 2 and the lamp body 1.

[0040] As an embodiment, the reflective portion 22 and the lens portion 21 can be different colors, so that the lampshade 2 has a two-color structure, and the lampshade 2 is extruded and formed in one piece by a two-color plastic extrusion mold. The PC material lampshade 2 is easy to form a reflective portion 22 and a lens portion 21 of different colors during production. The reflective portion 22 and the lens portion 21 are set to different colors. On the one hand, it can adapt to more light distribution designs. On the other hand, the reflective portion 22 can be made of opaque white material, and the lens portion 21 can be made of a highly transparent light-transmitting material to enhance the reflection and diffusion effect.

[0041] As an embodiment, the distance between the LED light source 3 and the opening is D1, and the distance between the LED light source 3 and the second surface 212 is D2, wherein 1 / 3D1<D2<2 / 3D1, preferably, D2=1 / 2D1. If the lens portion 21 is arranged too close to the closed side 11, the brightness of the light groove will be too low, and if the emitting surface of the lens portion 21 is arranged too far outward, the anti-glare effect cannot be achieved. In this embodiment, the lens portion 21 is located within a certain range of the lamp body 1, so that the brightness can be within a suitable range, and at the same time, the anti-glare effect can be achieved, and there can be enough space for the reflector 22 and the lamp body 1 to be connected and fixed.

[0042] The implementation principle of the present invention is as follows: the lens portion 21 of the present application is a convex mirror, and the light emitted by the LED light source 3 is transmitted to the first surface 211. Under the refraction of the first surface 211 and the second surface 212, the light emitted by the LED light source 3 will not be emitted directly, but will be emitted toward both sides of the inside of the lamp body 1, hiding the strong light inside the lamp body 1, achieving the effect of having brightness but not being able to directly see the strong light, so that the human eye cannot see the light source of the lamp within a certain angle range, achieving the effect of anti-glare, and protecting the human eye.

[0043] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0044] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will all be included in the scope of the claims of the present invention.
