Abstract:
1. A outdoor lamp with projection range adjustment, comprising: a lamp, an upper half of said lamp being obliquely covered by a shell body with a predetermined tilt angle defined by the angle between two parallel bottom edges of said shell body and two bottom edges on two corresponding lateral walls of said lamp, a left edge and a right edge of a front surface of said lamp being each provided with a guide groove, two lateral surfaces of said lamp being each provided with an arced angle adjustment tooth row; and a lampshade covering a lower half of said lamp and pivotally mounted on a rear portion of said lamp just under the shell body, whereby said lampshade can rotate about said rear portion of said lamp within an angular range defined by the angle between said bottom edges of said shell body and said bottom edges on said lateral walls of said lamp, two lateral edges of an inner wall of a front surface of said lampshade being each provided with an elongated rib for engaging a corresponding one of said guide grooves and thereby stabilizing the rotation of said lampshade; whereby the angular position of said lampshade with respect to said lamp is adjustable for enlarging and shrinking the light projection range of said lamp, and thus light pollution is controllable.
