[0002] A lens is an optical system used to change the light field distribution of an LED. When the light from an LED passes through a lens, it is refracted or reflected, thus concentrating the light and enhancing its efficiency and luminous efficacy.

[0003] Using a polarizing lens can not only improve the uniformity of the light spot formation, but also effectively increase the coverage distance of the light spot. For example, the prior patent with authorization announcement number CN209688744U discloses a polarizing lens for installation on a wall washer light, including: a light guide structure with a light-transmitting wall on the upper side; a first polarizing structure composed of multiple polarizing units arranged in a row; the polarizing unit has a first incident surface and a first exit surface; the first incident surface is attached to the upper surface of the light-transmitting wall; the orientation of the first exit surface forms a first preset angle with the upper surface of the light-transmitting wall; wherein, the light emitted by the wall washer light enters the first incident surface from the upper surface of the light-transmitting wall, is refracted by the polarizing unit, and exits the polarizing unit from the orientation of the first exit surface.

[0004] In the existing technology, polarization is achieved through refraction of each polarizing unit. However, the light mixing effect of the light spot formed by the lens is not good, and the uniformity of the light spot is insufficient, which affects the presentation effect of the light spot.

[0024] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0025] A mixed-light polarizing wall washer lens includes a lens body 1, which is used to receive light. The lens body 1 includes a freeform surface 15, a polarizing region 16, a reflecting surface 11, a first polarizing surface 13, a second polarizing surface 14, and a refractive surface 12. The reflecting surface 11 is used to reflect light to the polarizing region 16, and the refractive surface 12 is used to refract light to the polarizing region 16 or the freeform surface 15. The first polarizing surface 13 and the second polarizing surface 14 are respectively used to refract light to the freeform surface 15, and the refraction angles of the first polarizing surface 13 and the second polarizing surface 14 are arranged inconsistently. The polarizing region 16 and the freeform surface 15 are respectively used to converge light and project it outward to form a light spot.

[0026] In the aforementioned mixed-light polarizing wall washer lens, when in use, the light source emits light to the reflecting surface 11, the first polarizing surface 13, the second polarizing surface 14, and the refractive surface 12. The reflecting surface 11 reflects the light to the polarizing area 16, and the refractive surface 12 refracts the light to the polarizing area 16 or the freeform surface 15. The first polarizing surface 13 and the second polarizing surface 14 refract the light to the freeform surface 15. Finally, the light is converged by the polarizing area 16 and the freeform surface 15 and projected outward to form a light spot. With the combined effect of the polarizing area 16 and the freeform surface 15, it has a greater light output effect and helps to increase the light output distance, meeting the needs of wall washer lights. Furthermore, under the action of the first polarizing surface 13 and the second polarizing surface 14, the light mixing effect is enhanced, thereby improving the presentation effect of the light spot.

[0027] The first polarizing surface 13 and the second polarizing surface 14 are respectively arranged in an arched curved shape along the direction away from the light source, and the first polarizing surface 13 and the second polarizing surface 14 are respectively arranged in an oblique direction relative to the light source; in this way, it is convenient to realize the polarization of light, realize long-distance polarization, and meet the long-distance requirements of wall washer lights.

[0028] The refractive surface 12 is arranged in an arched curved shape along the direction towards the light source to improve the light focusing effect.

[0029] The refractive surface 12, the first polarizing surface 13, and the second polarizing surface 14 are arranged in sequence to reduce light loss and improve the formation effect and intensity of the light spot.

[0030] The first polarizing surface 13 and the second polarizing surface 14 are respectively provided with a sand-like layer, which is used to provide a light mixing effect; thus, the light mixing effect is improved under the action of the sand-like layer.

[0031] The mixed-light polarizing wall washer lens includes a third polarizing surface. The first polarizing surface 13, the second polarizing surface 14 and the third polarizing surface are arranged in sequence. The third polarizing surface is used to refract light to the freeform surface 15. The first polarizing surface 13, the second polarizing surface 14 and the third polarizing surface refract light in a mixed-light state.

[0032] In this way, the combined effect of the first polarizing surface 13, the second polarizing surface 14 and the third polarizing surface enhances the refraction area and direction of light, and improves the light mixing effect.

[0033] The mixed-light polarizing wall washer lens includes a fourth polarizing surface. The first polarizing surface 13, the second polarizing surface 14, the third polarizing surface and the fourth polarizing surface are arranged in sequence. The fourth polarizing surface is used to refract light to the freeform surface 15. The first polarizing surface 13, the second polarizing surface 14, the third polarizing surface and the fourth polarizing surface refract light in a mixed light state.

[0034] In this way, the combined effect of the first polarizing surface 13, the second polarizing surface 14, the third polarizing surface and the fourth polarizing surface enhance the refraction area and direction of light, and improve the light mixing effect.

[0035] The polarization zone 16 includes multiple polarizers 161, which are arranged in sequence. Each polarizer 161 is used to refract light and polarize light projection. Each polarizer 161 is arranged at an angle. Under the action of each polarizer 161, the wall washing surface is illuminated and the wall washing spot formed on the entire wall washing surface is more uniform.

[0036] The tilt angles of each polarizer 161 are arranged in a consistent manner, and the polarization is synchronized in different zones, so that the polarization angle difference of the overall polarization surface 121 is small, further improving the uniformity of the wall washing light spot.

[0037] Alternatively, the tilt angles of the various polarizers 161 are arranged in a different manner, which can play a role in light compensation for the wall washing surface, making the wall washing light spot formed on the entire wall washing surface more uniform.

[0038] The outer surface of the freeform surface 15 is provided with microstructures arranged in a scale-like pattern. In this way, the scale-like microstructures refract light along different regions and directions, thereby improving the light mixing effect.

[0039] Alternatively, the microstructure can be matte to improve the light mixing effect.

[0040] Alternatively, the outer surface of the freeform surface 15 can be arranged in a smooth manner to facilitate light transmission and improve light efficiency.

[0041] The lens body 1 includes a waterproof part 2, and a waterproof cavity is formed inside the waterproof part 2. The reflective surface 11, the first polarizing surface 13, the second polarizing surface 14 and the refractive surface 12 are all located in the waterproof cavity. Under the action of the waterproof part 2, it plays a waterproof role, preventing water vapor from entering the lens body 1 and ensuring the normal use of the lens body 11.

[0042] The waterproof part 2 is provided with two assembly columns, which are arranged at intervals and extend vertically in the direction away from the waterproof part. The assembly columns are used to assemble with external parts. In this way, the two assembly columns facilitate the assembly with the base and play a limiting role after assembly, thereby improving the assembly stability of the lens body 1.

[0043] The waterproof part 2 has three light-shielding surfaces 17, which are arranged sequentially and correspondingly along the outer periphery of the reflective surface 11. The three light-shielding surfaces 17 are fully corresponding to the reflective surface 11, and the light-shielding surfaces 17 are arranged to be opaque. Under the action of the light-shielding surfaces 17, the light is blocked, preventing light leakage and improving the performance of the lens body 1.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
