[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] Reference Figure 1-4 A parallel displacement dimmable lamp, comprising a lamp body 1 and a lamp board 3 detachably mounted on the lamp body 1, a lens 6 capable of position adjustment detachably mounted on the lamp body 1, at least two positioning holes are provided on both sides of the lamp body 1 and the lens 6, and the lens 6 can be mounted at a corresponding position on the lamp body 1 by embedding a positioning column 5 in the positioning hole;

[0030] The middle area of ​​the lens 6 is composed of a plurality of optically designed light-emitting surface structures, and the light-emitting surface includes a total reflection surface and a free-form surface.

[0031] The positioning holes on both sides of the lamp body 1 are first positioning holes 4 arranged vertically, and the positioning holes on both sides of the lens 6 are second positioning holes 7 arranged vertically. The first positioning holes 4 and the second positioning holes 7 are preferably provided in three configurations. The optical design of the lens 6 is a three-in-one design of T2, T3, and T4. When the relative position of the lens 6 relative to the LED particles of the lamp board 3 moves forward and backward by 1.5 mm, the light output is switched from one light type to another light type.

[0032] The structural design is as follows: three first positioning holes 4 are set on the lamp body 1, and the hole spacing is X mm; three fixing holes are set on the lamp board 3, and the hole spacing is X mm; three corresponding second positioning holes 7 are set on the lens 6, and the hole spacing is X-1.5mm.

[0033] Each positioning hole corresponds to a different light type (same logo); the positioning column 5 connects the lamp body 1, the lamp board 3, and the lens 6, and is assembled into different positioning holes corresponding to the required light type;

[0034] It should be noted that the three first positioning holes 4 on the lamp body 1 each correspond to a different light type, namely T2, T3, and T4 in sequence. Similarly, the three second positioning holes 7 on the lens 6 each correspond to a different light type, namely T2, T3, and T4 in sequence.

[0035] The lamp body 1 is also provided with a lens pressing plate 2 for positioning the lens 6 on the lamp body 1. The lens 6 can also be positioned on the lamp body 1 by screws. The diameter of the positioning column 5 is set to match the inner diameter of the first positioning hole 4 and the inner diameter of the lens 6. When assembling, first install the positioning column 5 into the light pattern corresponding to the lamp body 1, then align the three fixing holes of the lamp board 3 with the first positioning hole 4 on the lamp body 1, fix it with screws, put the corresponding second positioning hole 7 on the lens 6 onto the positioning column 5, fix it with the lens pressing plate 2 or screws, and the assembly is completed;

[0036] When switching the light type, open the lens pressing plate 2 or the screw, remove the lens 6, take out the positioning column 5 and put it back into the required light type positioning hole, put the lens 6 back, and install the lens 6 with the lens pressing plate 2 or the screw, and the light type switching is completed;

[0037] By moving the lens 6 to change the relative position between the lens 6 and the LED particles of the light board 3, the purpose of switching different light types is achieved, which is not limited to any lamp or the illustrated structure.

[0038] like Figure 5 and Figure 6 , design a street lamp polarizing lens 6 to deflect the light to one side of the road. At the same time, as the position of lens 6 moves, the size of the polarization angle can be adjusted. The light-emitting surface of lens 6 adopts a peanut-shaped free-form surface, and there is also a total reflection surface that reduces the light behind the pole; one side of each small area on lens 6 is a total reflection surface, and the curved surface shape conforms to the law of total reflection. When the light emitted from the LED hits the total reflection surface, the light will be reflected to one side of the road, and the other side is a peanut-shaped free-form surface. The surface shape of the free-form surface is designed according to the law of refraction to refract the light to one side of the road.

[0039] Embodiment 1: Figure 7 , design a polarized lens. When the LED is at the center, the polarization angle of lens 6 is 60 degrees. The street light distribution type corresponding to 60 degrees is T3 light type;

[0040] Embodiment 2: Figure 8 , after the position of lens 6 moves 1.5mm to one side, the polarization angle of lens 6 becomes larger, and the polarization angle increases to 70 degrees. The street light distribution type corresponding to 70 degrees is T4 light type;

[0041] Embodiment 3: Fig. 9 After the position of lens 6 moves 1.5 mm to the other side, the polarization angle of lens 6 becomes smaller, and the polarization angle is reduced to 45 degrees. The street lamp light distribution type corresponding to 45 degrees is T2 light type.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
