[0002] At present, most of the existing wall washers on the market rely on mechanical adjustment methods for angle adjustment, that is, the angle is changed by physically rotating the lamp body or reflector. However, this traditional adjustment method has many disadvantages. On the one hand, its adjustment range is relatively limited, which makes it difficult to meet diverse lighting needs; on the other hand, after long-term use, mechanical parts are prone to wear, which leads to structural seal failure, which not only affects the service life of the lamp, but also may cause safety hazards. In addition, during the adjustment process, there are often problems with uneven light spots or inconsistent brightness, which seriously affects the lighting effect and fails to provide users with a high-quality lighting experience.

[0003] To address this situation, a combination solution of matching LED lamps with corresponding lenses has emerged, that is, multi-level beam angle adjustment can be achieved through differentiated selection switches of LED lamps. However, the traditional solution can only achieve graded adjustment, and the distribution structure of LED lamps occupies a large space and cannot meet the needs of light intensity and uniformity adjustment. Summary of the invention

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the relevant inventions are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0019] The present invention provides an LED wall washer light angle adjustment system based on optical zoom, such as Figure 1 and Figure 2 As shown, it includes a lamp base 1 connected to a power module, on which is disposed an LED matrix module 2, an optical lens 3 covering the LED matrix module, and a control unit 4 electrically connected to the LED matrix module.

[0020] The LED matrix module includes at least two coaxially arranged LED light circles 20 with different diameters, and any LED light circle has a plurality of LED lamp beads evenly distributed in the circumferential direction.

[0021] The optical lens 3 comprises a conical lens barrel 31 and an end wall cover 32 arranged on the side of the conical lens barrel away from the LED matrix module. The diameter of the port of the conical lens barrel on the LED matrix module side is smaller than the diameter of the port of the conical lens barrel on the end wall cover side.

[0022] The control unit 4 includes a plurality of aperture controllers 40 which are arranged in one-to-one correspondence with the LED light apertures and are used to adjust the brightness of the LED lights.

[0023] Under the differentiated brightness adjustment states of several aperture controllers of the control unit, the LED matrix module has an infinitely adjustable range of the beam angle through the optical lens.

[0024] Specific implementation process and principle description: Generally, the beam angle corresponding to the inner circle LED light ring 20 is smaller, while the beam angle corresponding to the outer circle LED light ring 20 is larger. When only the inner circle is controlled to illuminate, its general beam angle is less than 15°, and when only the outer circle is controlled to illuminate, its general beam angle is greater than 30°.

[0025] Through the secondary optical design of the conical lens barrel, the inner and outer rings are coordinated with each other, and the beam angle can be infinitely adjusted within a certain range by controlling them separately according to the brightness.

[0026] In a specific embodiment, the number of LED lamp beads in any LED light ring is an even number, and the LED light ring has a first spacing aperture 21 and a second spacing aperture 22 formed by the LED lamp beads spaced apart from each other.

[0027] The aperture controller includes a first control module 41 matched with the first interval aperture for adjusting the brightness of the LED lamp beads in the first interval aperture, and a second control module 42 matched with the second interval aperture for adjusting the brightness of the LED lamp beads in the second interval aperture.

[0028] Specifically, the light beam is generally converged by the light beams of multiple LED lamp beads, and the light angle can be adjusted through the conical lens barrel to achieve beam angle adjustment. When adjusting the beam angle, there is also a need to adjust the uniformity of the halo illumination. Through the differentiated adjustment of the first interval aperture and the second interval aperture, the differentiated intensity uniformity adjustment needs under different beam angle states are met, making the lighting effect richer.

[0029] In a specific embodiment, the color temperatures of the LED lamp beads of the first interval aperture and the LED lamp beads of the second interval aperture are different. Specifically, the LED lamp beads of the first interval aperture can adopt a lower color temperature, such as 2000K~3000K, and the LED lamp beads of the second interval aperture can adopt a higher color temperature, such as 5000K~6000K, so that the lighting effect can be made more stable and rich by adjusting the color temperature of the interval lamp beads.

[0030] In a specific embodiment, Figures 1 to 3As shown, the LED matrix module includes a first LED light circle, a second LED light circle, and a third LED light circle arranged in a direction of increasing diameter, wherein the number of LED lamp beads in the second LED light circle is twice the number of LED lamp beads in the first LED light circle, and the number of LED lamp beads in the third LED light circle is twice the number of LED lamp beads in the second LED light circle.

[0031] Reference Figure 3 As shown, through differentiated control of the lamp beads of the first LED light circle, the second LED light circle, and the third LED light circle, differentiated beam angle adjustment requirements can be achieved, and light intensity adjustment can be achieved at the same time.

[0032] In a specific embodiment, the conical lens barrel has a first conical ring wall that cooperates with the first LED light circle, a second conical ring wall that cooperates with the second LED light circle, and a third conical ring wall that cooperates with the third LED light circle; conical ring transition sections are respectively provided between the second conical ring wall and the first conical ring wall and the third conical ring wall.

[0033] That is, a differentiated conical lens barrel design can be performed according to the required secondary optical design of the lens to meet the lighting effect requirements of smooth transition or aperture effect.

[0034] In a specific embodiment, the beam angle range of the LED matrix module through the optical lens is 11° to 36.8°.

[0035] Embodiment 1 The brightness of the first LED light circle is 100%, and the brightness of the second and third LED light circles are both 0. At this time, the beam angle is 11°.

[0036] Embodiment 2 The brightness of the first LED light circle is 100%, the brightness of the second LED light circle is 20%, and the brightness of the third LED light circle is 0. At this time, the beam angle is 16°.

[0037] Embodiment 3 The brightness of the first LED light circle is 0, the brightness of the second LED light circle is 100%, and the brightness of the third LED light circle is 0. At this time, the beam angle is 24.6° Embodiment 4 The brightness of the first LED light circle is 0, the brightness of the second LED light circle is 0, and the brightness of the third LED light circle is 100%. At this time, the beam angle is 36.8°.

[0038] Embodiment 5 The brightness of the first LED light circle is 100%, the brightness of the second LED light circle is 100%, and the brightness of the third LED light circle is 100%. At this time, the beam angle is 36.8°. At this time, there are strong light boundary light shadows of 11° and 24.6° on the wall.

[0039] Embodiment 6 The brightness of the first interval aperture of the first LED light circle is 50%, and the brightness of the second interval aperture is 0. The brightness of the first interval aperture of the second LED light circle is 50%, and the brightness of the second interval aperture is 0. The brightness of the third LED light circle is 100%. At this time, the beam angle is 36.8°. At this time, the outer side of the beam angle is uniform and the inner boundary of the angle is blurred, and the overall line beam is relatively uniform.

[0040] Through the solutions of Example 1 to Example 6, a control scheme for infinitely adjusting the angle of the light beam is realized, and at the same time, the light intensity coordination control function between adjacent LED light circles is provided, so that the lighting effect is richer.

[0041] In addition, while adjusting the light intensity, the color temperature of the LED lights can be adjusted at intervals to make the adjustment effect richer.

[0042] From the above description, we can find that the infinite adjustment of the beam angle can be achieved, breaking through the grading limitation of traditional mechanical adjustment, and preventing mechanical wear from affecting the service life. While satisfying the beam angle adjustment, the differentiated control of the phase-spaced lamp beads is achieved, making the light spot brightness control more abundant, satisfying the rich lighting effects of differentiated light intensity. Through the differentiated adjustment of brightness and color temperature, it is convenient to achieve targeted regulation in large-scale building lighting, landscape lighting and dynamic lighting scenes, and the adjustment response is fast.
