Abstract
An angle-adjustable recessed lamp structure comprises: a lamp bulb, a lamp holder, a rotatory carrier, and a mounting base. The rotatory carrier is securely screwed onto a track frame, which has a hollow sliding slot on the center of the arc-shaped body. The track frame is securely screwed on the fixing base via a fixing plate that locates on the rearward of the track frame. The fixing plate has two holding notches extending downward from both ends thereof for holding and positioning a rotation shaft. The rotation shaft is securely coupled with the coupling portion to enable the lamp holder to be rotatable by using pivotal connection between the rotatory carrier and the lamp holder. The lamp holder is upwards/downwards rotatable along the sliding slot within approximate 70 angles.
