[0029] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0030] See also Figure 1-Figure 10 The utility model provides a square wall washer lamp, a back plate 2 and a shell 1, the back plate 2 is in sheet shape, which can be installed on the wall. It can be installed on the wall by screws or by a mounting base. Therefore, a circular mounting groove 20 is provided on the back of the back plate 2, and a card hole is opened on the side wall of the mounting groove for carding on the mounting base on the wall.

[0031] The shell 1 is the lamp body, which can be installed on the back plate 2. In this embodiment, the cross-sections of the back plate 2 and the shell 1 are of the same shape and size, and can form an integrated structure after installation, with high installation reliability and good aesthetics; in this embodiment, the cross-section of the shell 1 is rectangular, preferably square, and a rounded rectangle, with a compact and beautiful appearance, a small thickness, and a flat structure, which improves the fit with the wall and does not produce an abrupt effect. A recess 10 is provided on the side wall of the shell 1, and the recess can be multiple and can be set on different side walls of the shell to achieve different wall beautification effects; the cross-section of the recess is a rectangular or trapezoidal structure, and the open end of the recess Facing the wall, an LED lamp 3 and a dimming board 4 are provided in the recess 10. The LED lamp 3 includes a substrate and LED lamp beads arranged on the substrate. Specifically, an installation opening is provided on the inner wall 11 of the recess (away from the open end), and strip grooves are provided on both sides of the installation opening. The two ends of the substrate are clamped in the strip grooves to achieve installation and fixation. In order to improve the sealing and prevent the entry of water vapor and dust, thereby extending the service life, a sealing gasket is provided between the substrate and the installation opening to achieve sealed installation; the LED lamp 3 is electrically connected to the circuit board 5 in the shell, and the light-emitting surface of the LED lamp 3 is perpendicular to the installation surface (bottom surface) of the shell 1, that is, after installation, the substrate is perpendicular to the wall.

[0032] For easy installation, the housing 1 is detachably mounted on the back plate 2 through a slot, see Figure 5-Figure 7 A strip-shaped slot 14 is provided on both sides of the back side of the shell 1, and the slot includes a first slot body 141 and a second slot body 142 which are connected to each other. The first slot body is located at the upper end of the second slot body, and its width is greater than the width of the second slot body; at the same time, a buckle 21 corresponding to the slot is provided on the back plate, and the buckle can be inserted from the first slot body, slide downward and enter the second slot body, thereby realizing a fixed connection; when disassembling, the shell is moved up to move the buckle 21 from the second slot body to the first slot body. At this time, the buckle can be pulled out of the first slot body, which can realize quick installation and disassembly of the shell.

[0033] There are two dimming plates 4, which are rectangular plates (sheets). The plane where they are located is perpendicular to the bottom surface of the shell, and they are rotatably installed on both sides of the LED lamp 3. The rotation axis of the dimming plate 4 is perpendicular to the installation surface (bottom surface) of the shell 1, that is, after installation, its rotation axis is perpendicular to the wall. The dimming plate 4 acts as a baffle to block the light. The light output angle of the LED lamp can be adjusted by rotating the dimming plate 4.

[0034] When the two dimming plates are rotated to the outermost end, the LED light has the largest light output angle, forming a fan-shaped light emitting area. Figure 8 .

[0035] When the two dimming plates are rotated to the innermost end, the light output angle of the LED lamp is the smallest, forming a linear light emitting area. Fig. 9 .

[0036] When the two dimming plates rotate in the same direction, the light output direction and sector angle of the LED lamp can be adjusted. Fig.10 .

[0037] In the present application, the sum of the widths b of the two dimming plates 4 is greater than the distance L between the two dimming plates 4. The dimming plate includes a rotating shaft 41 and a plate body fixed on the rotating shaft 41. The distance between the two dimming plates is the distance between the two rotating shafts 41; and the light output angle between the two dimming plates is greater than 0 degrees and less than or equal to 100 degrees, which can achieve adjustment of different light output angles and directions, and has high flexibility in use; at the same time, the distance h between the rotating shaft of the dimming plate 4 and the open end of the recess is greater than or equal to the width b of the dimming plate, which can improve the overall aesthetics and avoid exposure of the dimming plate.

[0038] At the same time, damping is provided between the dimming plate 4 and the shell. Specifically, damping is provided between the rotating shaft 41 and the shell. The damping has frictional force, which can improve the reliability of the dimming plate and avoid free flipping due to gravity or other influences. The above damping is achieved by the contact between the rubber contact piece or the plastic contact piece and the rotating shaft.

[0039] By rotating the two dimming plates, the LED lights can form light-emitting areas in different directions and angles, thereby forming different wall decoration effects. When multiple lights are used simultaneously (combined), various different patterns can be formed. It has high flexibility in use and greatly improves the aesthetic effect of the wall.

[0040] At the same time, a toggle switch 6 and an induction switch 51 are provided on the shell 1, which are electrically connected to the circuit board 5 and are used to control the working state of the LED lamp 3. Specifically, a groove 100 is provided on the installation surface (back side) of the shell 1, and the toggle switch 6 is installed in the groove 100. The toggle switch is used to switch the working state of the LED lamp, and its working state includes turning on, off and induction turning on the LED lamp; the induction switch 51 is installed on the top surface of the shell 1, and is used to turn on when sensing the human body, or automatically turn on when the light reaches a certain value.

[0041] In this embodiment, an installation area 1a and a battery area located at the outer edge of the installation area are provided in the shell 1, and the circuit board 5 is installed in the installation area 1a. One or more battery compartments 12 are provided in the battery area, and the battery compartments are electrically connected to the circuit board 5.
