AI Technical Summary
Traditional narrow-beam-angle wall washer lights cause brightness decay at the top of the wall and overexposure at the bottom as the projection distance increases, resulting in severe light spot fragmentation, especially in low-mounted environments where brightness imbalance is obvious.
By employing a refractive lens design, the angle between the inclined surface of the prism microstructure and the light-emitting surface decreases from top to bottom. Combined with a collimating lens and adjustment components, it achieves differentiated refraction of light and adjustment of the projection angle, enhancing the brightness at the top and suppressing overexposure at the bottom.
It improves the vertical uniformity of light distribution on the wall, avoids stray light, and enhances the uniformity of lighting effects and the ability to project light over long distances.

Abstract
Description
Technical Field
[0001] This application relates to the field of illumination device technology, specifically to an outdoor intelligent dimming lighting lamp. Background Technology
[0002] As a professional architectural lighting fixture, wall washer lights' core function is to achieve uniform illumination of building facades through directional projection, creating a continuous, dark-area-free visual effect. In landscape lighting, commercial complex lighting, and historical building lighting, the uniformity of wall lighting directly affects the final aesthetic performance. Traditional narrow-beam-angle wall washer lights have a small beam diffusion angle, concentrating the light in the near-field area of the fixture. This results in excessively high illuminance at the bottom of the wall, while the illuminance at the top decreases exponentially with increasing projection distance, creating a noticeable "bright bottom, dark top" light patch. In scenarios with low installation bases (such as the ground or low walls), narrow beam angles require extremely long projection distances to cover the wall height. However, in actual construction, space constraints often force close-range installation, further exacerbating the brightness imbalance. Utility Model Content
[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an outdoor intelligent dimming lighting fixture that improves brightness uniformity, and the technical solution adopted includes:
[0004] An outdoor intelligent dimming lighting fixture, comprising:
[0005] The lamp housing has a light-emitting section on the front that faces the wall;
[0006] A light source assembly is disposed inside the lamp housing, and a plurality of LED beads are provided on the front side of the light source assembly;
[0007] A refractive lens is disposed on the front side of the light source assembly. The rear side of the refractive lens is the light-incident surface, and the front side is the light-exit surface. A prism microstructure is provided on the light-exit surface. The bottom surface of the prism microstructure faces upward and the inclined surface faces downward. The angle between the inclined surface of the prism microstructure and the light-exit surface of the refractive lens decreases from top to bottom.
[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the light-emitting surface of the refractive lens is divided into multiple parts from top to bottom, and the angle between the inclined surface of the prism microstructure of each part and the light-emitting surface of the refractive lens is the same. The angle between the inclined surface of the prism microstructure of the multiple parts and the light-emitting surface of the refractive lens decreases linearly or non-linearly from top to bottom.
[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: it further includes a collimating lens disposed in the refracting lens and the light source assembly bracket.
[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the collimating lens is a Fresnel lens.
[0011] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the collimating lens is an aspherical Fresnel lens.
[0012] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: it further includes an adjustment component, the lamp housing is mounted on the adjustment component, and the adjustment component is used to adjust the orientation of the light-emitting part.
[0013] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the adjustment component includes a housing and a control board and a drive motor disposed in the housing. The control board is communicatively connected to the drive motor and is also communicatively connected to a mobile terminal through a wireless communication module. The two ends of the lamp housing are rotatably mounted on the housing through a rotating shaft, and one end of the rotating shaft extends into the housing. The drive motor is connected to one of the rotating shafts through a worm gear assembly.
[0014] The beneficial effects of this utility model are as follows: The outdoor intelligent dimming lighting lamp of this application reduces the angle between the inclined surface of the prism microstructure on the refractive lens and the light-emitting surface from top to bottom, so that the light undergoes differential refraction when passing through the refractive lens. In the top area of the refractive lens, the refraction angle of the refractive lens is larger, which enhances the light intensity at the top of the wall and compensates for the brightness attenuation at the top of the wall. In the bottom area of the refractive lens, the refraction angle of the light is smaller, which suppresses excessive downward light emission, avoids overexposure at the bottom of the wall, and improves the uniformity of the light distribution on the wall in the vertical direction.
[0015] Furthermore, the refractive lens described in this application only adjusts the vertical light distribution of the narrow beam without changing the horizontal beam angle, thus avoiding the generation of stray light. Attached Figure Description

[0025] Reference Figures 1-4 This application presents an embodiment of an outdoor intelligent dimming lighting lamp, which includes...
[0026] The lamp housing 10 has a light-emitting part 11 facing the wall on the front side; the light-emitting part 11 faces forward and towards the wall.
[0027] A light source assembly 20 is disposed inside the lamp housing 10, and a plurality of LED beads 30 are provided on the front side of the light source assembly 20;
[0028] A refractive lens 40 is disposed on the front side of the light source assembly 20. The rear side of the refractive lens 40 is the light-incident surface, and the front side is the light-exit surface, with the light-exit surface facing the light-exiting part 11. A prism microstructure 41 is provided on the light-exit surface. (Refer to the attached drawing.) Figure 4As shown, the bottom surface 411 of the prism microstructure 41 on the refractive lens 40 faces upward, the inclined surface 412 faces downward, and the angle between the inclined surface 412 of the prism microstructure 41 and the light-emitting surface of the refractive lens 40 decreases from top to bottom.
[0029] When light shines on the inclined surface 412 of the lens microstructure 41, the light is deflected towards the bottom surface 411 of the prism microstructure 41. The outdoor intelligent dimming lighting in this application reduces the angle between the inclined surface 412 of the prism microstructure 41 and the light-emitting surface from top to bottom, causing differentiated refraction of light as it passes through the refraction lens 40. The prism microstructure 41, with its different angle to the light-emitting surface of the refraction lens 40, exhibits different refraction effects on light, such as... Figure 3 As shown, in the top region of the refractive lens 40, the refractive lens 40 has a larger refraction angle for light, which enhances the light intensity at the top of the wall and compensates for the brightness attenuation at the top of the wall. In the bottom region of the refractive lens 40, the refraction angle for light is smaller, which suppresses excessive downward light emission, avoids overexposure at the bottom of the wall, and improves the uniformity of the light distribution on the wall in the vertical direction.
[0030] Furthermore, the refractive lens 40 described in this application only adjusts the vertical light distribution of the narrow beam without changing the horizontal beam angle, thus avoiding the generation of stray light.
[0031] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the light-emitting surface of the refractive lens 40 is divided into multiple parts from top to bottom, and the angle between the inclined surface 412 of the prism microstructure 41 of each part and the light-emitting surface of the refractive lens 40 is the same, and the angle between the inclined surface 412 of the prism microstructure 41 of the multiple parts and the light-emitting surface of the refractive lens 40 gradually decreases from top to bottom.
[0032] See attached document Figure 3 As shown, in this embodiment, the light-emitting surface of the refractive lens 40 is divided into three parts. The angles between the three parts and the light-emitting surface are α1, α2 and α3 from top to bottom. α1, α2 and α3 gradually decrease to reduce the processing accuracy requirements during production.
[0033] The technical solution adopted by one embodiment of the present invention to solve its technical problem is: it further includes a collimating lens 50 disposed in the bracket of the refracting lens 40 and the light source assembly 20.
[0034] The Fresnel lens converts the Lambertian divergent light emitted by the LED into near-parallel light, reducing the incident angle deviation of the light at the interface of the prism microstructure 41. This makes the refraction control of the light by the refracting lens 40 more precise, further narrowing the beam angle, reducing the total internal reflection loss on the surface of the prism microstructure 41, and enhancing the long-distance projection capability.
[0035] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the collimating lens 50 is an aspherical Fresnel lens. An aspherical Fresnel lens can suppress zonal diffraction, reduce diffraction efficiency, and ensure light uniformity.
[0036] In this embodiment, the lamp housing 10 is provided with a boss, and the collimating lens 50 and the refractive lens 40 are respectively placed on the boss and engaged with the boss by a locking arm.
[0037] Preferably, the lamp housing 10 is also included as an adjustment component 60, which is mounted on the adjustment component 60. The adjustment component 60 is used to rotate the lamp housing 10 to adjust the orientation of the light-emitting part 11, so as to ensure that the light is projected onto the wall.
[0038] Based on the above, the adjustment component 60 includes a housing 61 and a control board 62 and a drive motor 63 disposed within the housing 61. The control board 62 is communicatively connected to the drive motor 63 and is also communicatively connected to a mobile terminal via a wireless communication module. The lamp housing 10 is rotatably mounted on the housing 61 at both ends via rotating shafts 64, with one end of the rotating shafts 64 extending into the housing 61. The drive motor 63 is connected to one of the rotating shafts 64 via a worm gear assembly 65.
[0039] The control board 62 can respond to the signal from the mobile terminal and start the drive motor 63. The drive motor 63 drives the rotating shaft 64 to rotate through the worm gear, thereby adjusting the projection angle of the light-emitting part 11 of the lamp housing 10. After the adjustment is completed, the lamp housing 10 self-locks under the action of the worm gear assembly, realizing intelligent control of the projection light angle of the light-emitting part 11 of the lamp housing 10.
[0040] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
