[0001] The present invention relates to a wall washer lamp with a beam angle adjustment function, belonging to the technical field of beam angle adjustment of wall washer lamps for lighting. Background Art

[0002] In the current lighting field, especially in the application of lamps such as wall washer lamps, the diverse demand for beam angles is increasing day by day. The traditional method is to achieve it through mechanical light transmission angle adjustment, which has the situation of mechanical damage.

[0003] Currently, there is also a method of using an angle lens and an angle film to achieve different angle adjustments. However, this method has many drawbacks: on the one hand, during the process of adjusting the angle, light will be lost to varying degrees, resulting in a reduction in lighting efficiency; on the other hand, its structure realizes the adjustment by selecting different angle films, which not only increases the assembly man-hours but also raises the component cost, and is not conducive to the large-scale production and market promotion of products.

[0004] Therefore, researching and developing a technical solution that can effectively avoid the above problems and achieve efficient, low-cost, and flexible adjustment of the beam angle has become an urgent problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies of the above-mentioned existing technologies. Aiming at the problem that the beam angle cannot be flexibly adjusted in traditional technologies, a wall washer lamp with a beam angle adjustment function is proposed.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows: A wall washer lamp with a beam angle adjustment function, including a lamp holder plate connected to a power supply, a lamp group arranged on the lamp holder plate, and a control unit electrically connected to the lamp group; The lamp group includes a first LED lamp and two second LED lamps respectively arranged on both sides of the first LED lamp, and the first LED lamp and the two LED lamps are linearly and evenly spaced; The beam angle of the first LED lamp is 11°, and the beam angle of the second LED lamp is 11° * 55°; The control unit includes a first current controller for adjusting the working current of the first LED lamp and communicatively connected to the first LED lamp, and a second current controller for synchronously adjusting the working current of the second LED lamps and communicatively connected to the two second LED lamps; In the state where the control unit differentially adjusts the working currents of the first LED lamp and the second LED lamps, the wall washer lamp has a stepless regulation range of the beam angle between 11° and 55°.

[0007] Preferably, the beam angle of the second LED lamp includes a first beam angle of 11° and a second beam angle of 55°, and the first direction of the first beam angle is perpendicular to the second direction of the second beam angle; The first directions of the first beam angles of the two second LED lamps are parallel.

[0008] Preferably, the first LED lamp includes a first lens for beam angle limitation, and the second LED lamp includes a second lens for beam angle limitation.

[0009] Preferably, the operating current adjustment range of the first LED lamp and the second LED lamp is 0 mA to 500 mA.

[0010] Preferably, the wall washer lamp has at least three fixed current cooperation control points for quickly determining the beam angle.

[0011] Preferably, the wall washer lamp includes a first current cooperation control point, a second current cooperation control point, and a third current cooperation control point; At the first current cooperation control point, the operating current of the first LED lamp is 100 mA, the operating current of the second LED lamp is 500 mA, and the beam angle is 11° * 55°; At the second current cooperation control point, the operating current of the first LED lamp is 250 mA, the operating current of the second LED lamp is 250 mA, and the beam angle is 11° * 36.3°; At the third current cooperation control point, the operating current of the first LED lamp is 500 mA, the operating current of the second LED lamp is 100 mA, and the beam angle is 11° * 24.6°.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The following further elaborates on the present application with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant invention and not for limiting the invention. Additionally, it should be noted that for the sake of description, only parts related to the relevant invention are shown in the drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] The present invention provides a wall - washing lamp with a beam angle adjustment function, as Figure 1 shown, including a lamp base plate 1 connected to a power source, a lamp group 2 arranged on the lamp base plate, and a control unit 3 electrically connected to the lamp group.

[0025] The lamp set 2 includes a first LED lamp 21 and two second LED lamps 22 respectively arranged on both sides of the first LED lamp. The first LED lamp and the two LED lamps are linearly and evenly spaced.

[0026] The beam angle of the first LED lamp is 11°, and the beam angle of the second LED lamp is 11° * 55°.

[0027] The control unit includes a first current controller for adjusting the working current of the first LED lamp and communicatively connected to the first LED lamp, and a second current controller for synchronously adjusting the working currents of the two second LED lamps and communicatively connected to the two second LED lamps.

[0028] In the state where the control unit differentially adjusts the working currents of the first LED lamp and the second LED lamp, the wall washer lamp has a stepless regulation range with a beam angle between 11° and 55°.

[0029] Specifically, the first LED lamp has a fixed-angle beam angle, while the second LED lamp has vertically and horizontally different beam angles. Through the two second LED lamps and the first LED lamp, a mutually influencing light illumination cooperation is achieved, so as to meet the flexible adjustment requirements of the beam angle.

[0030] Specifically, the beam angle and beam intensity of the second LED lamp itself can be adjusted by the magnitude of the working current of the second LED lamp, and the beam intensity of the first LED lamp itself can be adjusted by the magnitude of the working current of the first LED lamp. By combining the beam angles and beam intensities of the two, a differential beam angle adjustment can be achieved, and at the same time, its light energy will not be additionally lost.

[0031] In a specific embodiment, the beam angle of the second LED lamp includes a first-direction beam angle of 11° and a second-direction beam angle of 55°. The first direction of the first-direction beam angle is perpendicular to the second direction of the second-direction beam angle; the first directions of the first-direction beam angles of the two second LED lamps are parallel.

[0032] That is, the second LED lamp has vertically and horizontally beam angles, so that it can achieve uniform cooperative cooperation with the first LED lamp in the middle, thereby forming a relatively uniform lighting effect.

[0033] In a specific embodiment, the first LED lamp includes a first lens for beam angle limitation, and the second LED lamp includes a second lens for beam angle limitation.

[0034] That is, the beam angle adjustment of the lamp itself is achieved through the lens, meeting the optical adjustment requirements.

[0035] The operating current adjustment range of the first LED lamp and the second LED lamp is 0 mA to 500 mA. That is, it can meet the demand for stepless adjustment of the operating current.

[0036] In a specific embodiment, the wall washer lamp has at least three fixed current coordination control points for quickly determining the beam angle.

[0037] Specifically, during the response adjustment process, the operating current is generally adjusted step by step. For example, the first LED lamp emits a beam with a small angle, while the second LED lamp emits a dispersed beam with a large angle. When adjusting the adaptable beam, rapid positioning can be achieved through the fixed current coordination control points. Based on this control point, the operating current of the first or second LED lamp can be gradually increased or decreased. In this way, the response is relatively efficient.

[0038] In a specific embodiment, the wall washer lamp includes a first current coordination control point, a second current coordination control point, and a third current coordination control point.

[0039] Embodiment 1 As Figure 2 shown, the operating current of the first LED lamp is 0 mA, the operating current of the second LED lamp is 500 mA, and the beam angle is 11° * 55°.

[0040] Embodiment 2 As Figure 3 shown, the operating current of the first LED lamp is 500 mA, the operating current of the second LED lamp is 0 mA, and the beam angle is 11°.

[0041] Embodiment 3 As Figure 4 shown, at the first current coordination control point, the operating current of the first LED lamp is 100 mA, the operating current of the second LED lamp is 500 mA, and the beam angle is 11° * 55°.

[0042] Embodiment 4 As Figure 5 shown, at the second current coordination control point, the operating current of the first LED lamp is 250 mA, the operating current of the second LED lamp is 250 mA, and the beam angle is 11° * 36.3°; Embodiment 5 As Figure 6 shown, at the third current coordination control point, the operating current of the first LED lamp is 500 mA, the operating current of the second LED lamp is 100 mA, and the beam angle is 11° * 24.6°.

[0043] As can be seen from the above embodiments, by adjusting the working current, the flexible adjustment requirement of the overall beam angle can be met for the coordinated operation of three LED lamps based on the original beam angle.

[0044] From the above description, it can be found that by designing the initial beam angle and adjusting the working current in cooperation with the middle LED lamp by the two side LED lamps, the stepless control requirement of the beam angle of the wall washing lamp can be met. The adjustment is simple and convenient, and the lighting effect is relatively rich. There are current coordination control points, which can quickly adjust the fixed points according to the requirements of the lighting effect and then make fine adjustments of increasing or decreasing one by one, and the response to the required lighting effect is more efficient.

[0045] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, so that a process, method, article or device / equipment comprising a series of elements includes not only those elements but also other elements not explicitly listed, or also elements inherent in these processes, methods, articles or devices / equipment.

[0046] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
