Also, a first feature "on," "above," and "over" a second feature may mean that the first feature is directly above or obliquely above the second feature, or that only the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Referring to fig. 1-8, the present invention discloses an adjustable wall washer lamp, which comprises a lamp body assembly 100, wherein end caps 200 are disposed at two ends of the lamp body assembly 100, the end caps 200 are rotatably connected to a support arm 300, and the support arm 300 is connected to a track joint 400; the end cap 200 comprises an outer cap body 210 and an inner cap body 220, a cavity is arranged inside the end cap 200, a circular arc-shaped limiting groove 211 is formed in the outer cap body 210, the support arm 300 is used for being connected with a connecting hole formed in one end of the outer cap body 210, the limiting screw 500 penetrates through the limiting groove 211 and then is inserted into the connecting hole, and the outer cap body 210 is located between a nut of the limiting screw 500 and the support arm 300.

Thus, the end caps 200 at the two ends of the lamp body assembly 100 are rotatably connected with the support arm 300, and the rotatable connection structure can be completed simply by using the limit screw 500 through the connection hole on the support arm 300 and the structure of the end caps 200, so that the structure is simple and easy to produce; the light emitting angle of the wall washer can be adjusted by directly rotating the lamp body assembly 100, and the adjustment is convenient; in addition, the lamp body assembly 100 is coupled to the rail joint 400, so that the lamp body assembly 100 can be moved to adjust the light emitting position.

Specifically, referring to fig. 2, 3 and 4, the outer cover 210 is provided with two arc-shaped limiting grooves 211 which are oppositely arranged, the number of connecting holes on each support arm 300 is two, the number of the limiting screws 500 corresponds to the number of the connecting holes, and the connecting holes are in threaded fit with the limiting screws 500. A stop washer 600 is arranged between the outer cover body 210 and the nut of the limit screw 500, two convex columns 610 are arranged on the stop washer 600, the two convex columns 610 are respectively inserted into the two limit grooves 211, threaded holes are arranged on the convex columns 610, and the limit screw 500 passes through the threaded holes of the convex columns 610; a flat gasket 700 is arranged between the stop gasket 600 and the nut of the limit screw 500, a flat gasket 700 is also arranged between the outer cover body 210 and the connecting hole, and a positioning hole 710 corresponding to the limit screw 500 is arranged on the flat gasket 700. In practical implementation, when the lamp body assembly 100 is rotated, the support arm 300 and the limit screw 500 are fixed relatively, and the lamp body assembly 100 is rotated; during the rotation process, the limiting groove 211 on the outer cover 210 of the end cap 200 moves along the limiting screw 500, and the arc length of the arc-shaped limiting groove 211 affects the rotatable angle of the lamp body assembly 100; it should be noted that, the convex column 610 on the stop washer 600 contacts with the groove wall of the limit groove 211, so as to prevent the external thread on the limit screw 500 from scratching the limit groove 211; in addition, by providing the flat gasket 700, friction between the end cap 200 and the support arm 300 and the nut of the limit bolt is increased, so that the lamp body assembly 100 can be fixed at the rotated position after rotating the lamp body assembly 100.
