[0002] Wall washer lights are a common type of lighting fixture. In addition to their downward vertical illumination function, they also have the ability to deflect at a certain angle to both sides to achieve angle adjustment. For example, CN202321905217.8 describes an angle-adjustable wall washer downlight, which provides a built-in precise adjustment scheme to facilitate wall washer angle adjustment without disassembling the lamp body. This includes a lamp body assembly, an inner ring frame, a face frame assembly, an anti-glare cover, and an angle adjustment assembly. The angle adjustment assembly includes an adjustment knob, a first transmission assembly, and a second transmission assembly. The adjustment knob is located on the inner ring frame. When the adjustment knob is rotated, the first transmission assembly drives the lamp body assembly to move left and right. When the lamp body assembly moves, the second transmission assembly drives the lamp body assembly to tilt.

[0003] While it can meet general usage needs, it lacks a corresponding counterweight structure, which affects the overall weight of the wall washer downlight and thus its stability. Furthermore, due to its structural limitations, it cannot effectively assemble a counterweight structure or ensure heat dissipation performance, thus limiting its applicability and making it difficult to meet market demands.
