For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example:

[0031] like Figures 1 to 6As shown, a reflective structure comprises: a plurality of reflective members 1, wherein the plurality of reflective members 1 are connected to form a chain structure, wherein the reflective member 1 comprises a first reflective surface 2, a second reflective surface 3 and a third reflective surface 4, wherein one side of the second reflective surface 3 and one side of the third reflective surface 4 are respectively arranged at two ends of the first reflective surface 2, one side of the second reflective surface 3 of the reflective member 1 is connected to one side of the third reflective surface 4 of the adjacent reflective member 1, an angle is formed between the second reflective surface 3 and the third reflective surface 4 of the reflective member 1, a light outlet 5 is formed on the side of the second reflective surface 3 and the third reflective surface 4 away from the first reflective surface 2, and an angle is formed between the second reflective surface 3 of the reflective member 1 and the third reflective surface 4 of the adjacent reflective member 1.

[0032] The distance between the second reflecting surface 3 and the third reflecting surface 4 increases as they are away from the first reflecting surface 2 .

[0033] The first reflecting surface 2 is convex in a direction away from the light outlet 5 in a vertical plane and in a horizontal plane respectively.

[0034] The first reflecting surface 2 is a parabola, the second reflecting surface 3 and the third reflecting surface 4 are planes, and the angles formed between the first reflecting surface 2 and the second reflecting surface 3 and the third reflecting surface 4 are respectively greater than 95°, which is suitable for reflecting the light projected onto the first reflecting surface 2 to form parallel light. After the light is reflected by the second reflecting surface 3 and the third reflecting surface 4, the refraction angle of the light is expanded in the horizontal direction, thereby increasing the lighting range of the light.

[0035] The first reflecting surface 2 is provided with patterns or leather grains, and the second reflecting surface 3 and the third reflecting surface 4 are provided with patterns, which can further improve the final lighting uniformity.

[0036] It also has a light source 9, which is arranged just above the first reflecting surface 2. In the present embodiment, the light source 9 is a single LED. The light emitted by the light source 9 is divided into a first light group 6, a second light group 7 and a third light group. The color of the LED light source 9 includes but is not limited to red, white and yellow. The surface of the reflecting member 1 can be aluminum-plated or made of white reflecting material.

[0037] The first light group 6 is directly emitted from the light outlet 5 after being reflected by the first reflection surface 2; the second light group 7 is projected to the second reflection surface 3 after being reflected by the first reflection surface 2, and is emitted from the light outlet 5 after being reflected by the second reflection surface 3; the third light group 8 is projected to the third reflection surface 4 after being reflected by the first reflection surface 2, and is emitted from the light outlet 5 after being reflected by the third reflection surface 4 for the second time.

[0038] That is to say, the first light group 6 can form collimated outgoing light after one reflection, and the second light group 7 and the third light group 8 can form collimated outgoing light after two reflections respectively.

[0039] This embodiment uses one or more reflections in the system so that when each viewing angle is illuminated, there is little difference in brightness, and ultimately a uniform emitted light is formed, thereby rationally utilizing light efficiency and evenly distributing light, thereby achieving the purpose of improving lighting uniformity. In addition, this solution uses the mutual cooperation between the first reflection surface 2, the second reflection surface 3 and the third reflection surface 4 so that the controllable area of ​​a single LED is at least 1.2 times the controllable area of ​​the prior art, thereby saving LEDs, and a single LED can achieve the same or even larger lighting area as the prior art, thereby achieving the purpose of cost reduction.

[0040] In summary, based on the above-mentioned ideal embodiment of the utility model, through the above-mentioned description, relevant staff can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of the utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
