Abstract
Description
Technical Field
[0001] This utility model relates to the field of wall washer light technology, and in particular to a polarizing lens and a wall washer light. Background Technology
[0002] Wall washer lights use LEDs as the light source. The light emitted by the wall washer lights shines on the wall to present a water-washing-like lighting effect. Wall washer lights are mainly used for architectural decorative lighting and to outline the contours of large buildings.
[0003] Currently, common wall washer lights on the market consist of a long, narrow light body, a light source board, and a glass panel. The light source board has multiple circular lenses covering it, which control the light emitted from the light source board so that most of the light exits through the glass panel. However, the polarization effect of the lenses in existing technology is poor, making it difficult to meet customer needs for the light projection range.
[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a polarizing lens and a wall washer light, which aims to solve the technical problems of poor polarization effect and the inability of the light projection range to meet customer needs in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A polarizing lens includes a lens body extending along its length. The lens body includes a first light-incident surface, a second light-incident surface, a total reflection surface, and a light-exiting surface. The light-exiting surface is located at the top of the lens body and is curved. The first light-incident surface and the second light-incident surface are located at the bottom of the lens body and have an included angle. The total reflection surface is located close to the second light-incident surface and is used to totally reflect light rays incident from the second light-incident surface to the light-exiting surface. The first light-incident surface refracts incident light rays to the light-exiting surface.
[0008] Furthermore, the light-emitting surface includes a light-emitting plane and a light-emitting curved surface. The light-emitting plane is located close to the total reflection surface, and the light-emitting curved surface is an arc surface that protrudes outward toward the lens body.
[0009] Furthermore, the first light-incident surface is an arc-shaped surface protruding outwards from the lens body; the second light-incident surface is a plane.
[0010] Furthermore, the lens body is provided with several legs, and multiple legs are used to mount the lens onto the light source board.
[0011] A wall washer light includes a lamp body, a light source board, a cover plate, end caps, and a polarizing lens. The light source board includes a substrate disposed in the lamp body and a plurality of LED beads soldered on the substrate. The polarizing lens is disposed on the substrate, and the LED beads are located below the included angle. The cover plate is disposed on the top of the lamp body, and two end caps are respectively disposed at the two ends of the lamp body.
[0012] Furthermore, there are multiple polarizing lenses, which are arranged sequentially along the length of the light source plate.
[0013] Furthermore, the bottom of the lamp body is provided with a mounting groove, and the light source board is disposed in the mounting groove.
[0014] Furthermore, the top of the lamp body is provided with two symmetrical stepped sections, and the cover plate is located on the two stepped sections.
[0015] Beneficial effects:
[0016] This invention provides a polarizing lens and a wall washer light. The lens body is provided with a first light-incident surface, a second light-incident surface, a total reflection surface, and a light-emitting surface, with an angle between the first and second light-incident surfaces. LED beads on the light source board are located below this angle. Part of the light emitted by the LED beads is refracted through the first light-incident surface to the light-emitting surface, while the other part passes through the second light-incident surface and directly enters the total reflection surface. The total reflection surface reflects this part of the light back to the light-emitting surface. The light source achieves a large-angle polarization effect after being controlled by the polarizing lens, ensuring that the light projection range meets customer needs. Furthermore, the various colors of light emitted by the LED beads are refracted and reflected before exiting through the light-emitting surface, achieving a uniform, non-separated multi-color light mixing effect.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0025] Please see Figures 1 to 2 As shown, this utility model provides a polarizing lens, including a lens body 1 that extends along its length. The lens body 1 includes a first light-incident surface 11, a second light-incident surface 12, a total reflection surface 13, and a light-exiting surface 14. The light-exiting surface 14 is located at the top of the lens body 1 and is curved. The first light-incident surface 11 and the second light-incident surface 12 are located at the bottom of the lens body 1, and there is an included angle 15 between the first light-incident surface 11 and the second light-incident surface 12. The total reflection surface 13 is located close to the second light-incident surface 12 and is used to completely reflect the light rays incident from the second light-incident surface 12 to the light-exiting surface 14. The first light-incident surface 11 refracts the incident light rays to the light-exiting surface 14.
[0026] A polarizing lens covers the light source plate 3 to control the light emitted from the light source plate 3, achieving a polarized light effect. During the light emission process, part of the light emitted from the light source plate 3 enters the lens body 1 through the first light-incident surface 11, is refracted, and is emitted from the light-out surface 14. Since the light-out surface 14 is curved and close to the first light-incident surface 11, the refracted light is emitted uniformly. The other part of the light enters the total reflection surface 13 through the second light-incident surface 12. This part of the light is completely refracted by the total reflection surface 13 and is emitted from the light-out surface 14. Under the action of the first light-incident surface 11 and the total reflection surface 13, a large-angle polarization effect is achieved, so that the projection range can meet the customer's needs. In addition, when the light source 3 is a multi-color light source, the emitted light of each color is refracted and reflected before being emitted from the light-out surface, achieving a uniform multi-color mixing effect without color separation.
[0027] In the above, the light-emitting surface 14 is a curved surface, which can increase the light-emitting area compared to when the light-emitting surface 14 is a flat surface, so as to achieve a large area light-emitting effect.
[0028] In a preferred embodiment, see [reference] Figure 2 , 5 The light-emitting surface 14 includes a light-emitting plane 141 and a light-emitting curved surface 142. The light-emitting plane 141 is located close to the total internal reflection surface 13, and the light-emitting curved surface 142 is an arc surface protruding outward from the lens body 1. By setting the outwardly protruding light-emitting curved surface 142, the distance between the light source plate 3 and the light-emitting curved surface 142 is increased, improving the uniformity of light emission from the light-emitting curved surface 142, thereby making the light emission from the light-emitting surface 14 more uniform. By setting the light-emitting plane 141, the height of the lens body 1 can be reduced, thereby effectively reducing the height of the wall washer light.
[0029] In a preferred embodiment, see [reference] Figure 2 , 5 The first light-incident surface 11 is an arc surface that protrudes outward toward the lens body 1, so that the light from the light source plate 3 is focused as much as possible onto the light-emitting curved surface 142 under the refraction of the first light-incident surface 11, so that more light is focused on the side to be polarized, so as to achieve a better polarization effect; the second light-incident surface 12 is a plane, which allows light to pass through the second light-incident surface 12 and directly reach the total reflection surface 13 for total reflection.
[0030] In the above, the total reflection surface 13 is a parabolic surface that reflects light in total, so that the light rays that reach the total reflection surface 13 from the second light-incident surface 12 can achieve total reflection. At the same time, the light rays after total reflection are emitted from the light-out surface 14.
[0031] In a preferred embodiment, see [reference] Figure 2 , 4The lens body 1 is provided with a plurality of legs 16, which are used to mount the lens body 1 on the light source plate 3. Through the above arrangement, the lens body 1 can be stably mounted on the light source plate 3.
[0032] In summary, by setting a first light-incident surface 11 and a second light-incident surface 12, with an included angle of 15 between the first light-incident surface 11 and the second light-incident surface 12, part of the light emitted from the light source plate 3 is refracted after passing through the first light-incident surface 11 and reaches the light-emitting surface 14 for emission, while the other part of the light passes through the second light-incident surface 12 and enters the total reflection surface 13. This part of the light undergoes total reflection after passing through the total reflection surface 13 and is finally emitted from the light-emitting surface 14, thus achieving a large-angle polarization effect of the lens body 1, so that the projection range of the light meets the customer's needs.
[0033] Please see Figures 1 to 5 As shown, this utility model provides a wall washer light, including a lamp body 2, a light source board 3, a cover plate 4, end caps 5, and the polarizing lens. The light source board 3 includes a substrate 31 disposed inside the lamp body 2 and a plurality of LED beads 32 soldered on the substrate 31. The polarizing lens is disposed on the substrate 31, and the LED beads 32 are located below the included angle 15. The cover plate 4 is disposed on the top of the lamp body 2, and the two end caps 5 are respectively disposed at the two ends of the lamp body 2.
[0034] The light emitted by the LED bead 32 is polarized after being controlled by a polarizing lens, thus ensuring that the projection range of the light meets customer needs. When the LED bead 32 is a two-color, three-color, or four-color light source, the emitted light of each color is refracted by the polarizing lens to achieve a mixed light effect, and the mixed light is uniform and does not separate colors. The light-emitting surface 14 is located below the cover plate 4 so that most of the controlled light can pass through the cover plate 4 and be emitted into the environment.
[0035] In this embodiment, see Figure 5 The light-emitting plane 141 is parallel to the cover plate 4. By reducing the height of the polarizing lens, the height of the lamp body 2 is effectively reduced.
[0036] In this embodiment, see Figure 4 The substrate 31 is provided with a plurality of mounting holes 33 corresponding one-to-one with the support 16. The support 16 is inserted into the mounting holes 33, realizing the rapid installation of the polarizing lens.
[0037] Specifically, each support leg 16 has two symmetrically arranged locking feet 161 at its bottom, with a gap between the two locking feet 161, and the outer diameter of the two locking feet 161 matches the mounting hole 33, so that after the two locking feet 161 are inserted into the mounting hole 33, the mounting hole 33 can lock the two locking feet 161 to improve the stability of the polarizing lens.
[0038] In a preferred embodiment, see [reference] Figure 3 The polarizing lens comprises multiple lenses arranged sequentially along the length of the light source plate 3. The ends of these lenses are joined together to form a continuous lens. Combining different numbers of polarizing lenses allows for compatibility with light source plates 3 of varying lengths, offering high installation flexibility. Furthermore, a shorter length for the polarizing lenses helps reduce production costs and facilitates better quality control.
[0039] As mentioned above, the lamp body 2 is an integrally extruded aluminum profile. Aluminum profiles are lightweight, easy to dissipate heat, and have relatively low production costs, making them suitable for use in various environmental conditions.
[0040] In a preferred embodiment, see [reference] Figure 4 The lamp body 2 has a mounting groove 21 at its bottom, and the light source plate 3 is located in the mounting groove 21. Specifically, the light source plate 3 is fixed in the mounting groove 21 by adhesive, so that the bottom of the light source plate 3 is in contact with the bottom of the lamp body 2, which facilitates heat exchange between the light source plate 3 and the lamp body 2, thereby improving the heat dissipation efficiency of the light source plate 3.
[0041] In a preferred embodiment, see [reference] Figure 4 The lamp body 2 has two symmetrical stepped portions 22 on its top, and the cover plate 4 is located on the two stepped portions 22. Specifically, the stepped portion 22 has a downwardly recessed portion 23, which is used to fill glue to stably install the glass panel on the two stepped portions 22.
[0042] In a preferred embodiment, see [reference] Figure 3 , 4 The lamp body 2 has circular grooves 24 on both sides. The end caps 5 are connected to the circular grooves 24 by screws 51, so as to stably install the end caps 5 at the ends of the lamp body 2. The two end caps 5 cooperate to seal the lamp body 2, so as to achieve the function of dustproof and waterproof. In addition, a bracket can be slidably connected to the circular grooves 24, and the lamp body 2 can be stably fixed to the mounting wall by the bracket. The bracket is not shown in the attached drawings.
