ABSTRACT:
An outdoor lamp with projection range adjustment having a freely adjustable lampshade for restricting light projection range of the lamp, thereby controlling light pollution, comprises a lamp partially covered by a shell body and a lampshade pivotally mounted on the lamp. Two parallel bottom edges of the shell body extend on two corresponding lateral walls of the lamp with a predetermined angle, so that the lampshade can freely rotate about a rear portion of the lamp in a range of the predetermined angle. Further, two lateral surfaces of the lamp are each provided with an arced angle adjustment tooth row, and two lateral inner walls of the lampshade are each provided with a projected dot for engaging a corresponding angle adjustment tooth row, whereby a stepless angle adjustment can be realized.
