Abstract
An aiming device for track lighting includes an elbow member rotatively mounting a lamp housing to a vertical extension tube. The elbow member has an upper end connected to a lower end of the extension tube for rotation in a horizontal plane through 355 and a lower, transverse end formed with an annulus of locking teeth and an internal rotation limiting rib. The lamp housing has a lateral mounting plate with a connecting turret with a rim of locking teeth, a hub formed with a screw socket and a pair of radially extending rotation preventing members enclosing between them a lead receiving aperture within the turret. A clamping screw can be manually adjusted between a locking position clamping the mounting plate immovably to the elbow by locking engagement of respective teeth and a release position permitting vertical rotation of the lamp housing limited by engagement of the rotation limiting rib and rotation preventing members.
