[0002] The wall washing lamp can be installed near the corner of the ceiling, and the light is used for flood lighting on the wall. In order to avoid causing glare, the LED lamp bead is retracted in the reflector of the lamp, and is not exposed. Since the LED lamp bead is retracted in the shell of the lamp, the lateral light emission of the LED lamp bead is blocked by the shell, so that the area of the wall surface close to the ceiling forms a dark area, which affects the lighting effect. SUMMARY
[0003] The utility model discloses a linear wall washing lamp without dark area, which can avoid the dark area of the wall surface close to the ceiling, and make the light spot transition natural, soft and uniform.

[0006] Specifically, the first reflector is arranged at the shell slot, the front reflection concave surface is arranged on the front wall of the first reflector, the front reflection concave surface intersects with the top edge of the front wall of the first reflector, so that the edge profile of the front reflection concave surface is in the shape of D pointing downward, and the front reflection concave surface is below the light emitting surface of the LED module.
[0007] Specifically, the rear wall of the first reflector is provided with a rear buckle, the rear wall of the inner cavity of the shell is provided with a rear clamping groove, and the rear buckle is connected with the rear clamping groove.
[0008] Specifically, the reflection arc surface is below the light emitting surface of the LED module, the reflection arc surface gradually deviates from the LED module from top to bottom, the convex strip is along the upward and downward direction, and the convex strip gradually deviates from the LED module from top to bottom.
[0009] Specifically, the cross section profile of the convex strip is in the shape of C.
[0010] Specifically, a second reflector is provided at the slot of the housing. The second reflector includes a front plate and several reflectors. The several reflectors are fixed to the rear wall of the front plate. The rear end of the reflector abuts against the front wall of the first reflector. A positioning rod is provided at the rear end of the reflector. A positioning hole is provided on the front wall of the first reflector. The positioning rod is inserted into the positioning hole.

[0015] To avoid areas where the walls are close to the ceiling ( Figure 6 Area A (in the middle) is a dark area due to lack of light. A first reflector is installed at the slot of the housing, and the front wall of the first reflector has a front reflective concave surface. The side light emitted from the light-emitting surface of the LED module shines on the front reflective concave surface and is reflected back to area A, thus preventing the dark area in area A from occurring. The front reflective concave surface is matte silver (near mirror), which has both specular reflection and diffuse reflection effects, thereby creating a certain scattering and mixing effect, making the light spot transition in area A natural and soft, and the illumination uniform.
[0016] The reflective arc surface and multiple convex strips can further enhance the uniformity of light mixing within the second reflector, while also increasing the amount of light projected onto the front reflective concave surface. This allows the front reflective concave surface to project more already mixed light onto area A, ensuring a smooth transition of the light spot in area A, with no color separation and uniform illumination.
[0017] The reflective curved surface and multiple raised strips can be glossy black or light black chrome for better anti-glare effect. The reflective curved surface and multiple raised strips can also be matte silver (near mirror finish), which will make the light spot effect in area A more uniform and softer.

[0041] The working principle of the utility model is as follows:

The side light emitted from the light-emitting surface of the LED module 2 shines on the front reflective concave surface 31 and is reflected to area A, thus avoiding the dark area in area A. The front reflective concave surface 31 is matte silver (near mirror), which has both specular reflection and diffuse reflection effects, thus forming a certain light scattering and mixing effect, making the light spot transition in area A natural and soft, and the illumination uniform.
