Abstract
A recessed lamp structure comprises: a lamp bulb, a lamp holder, a rotatory carrier and an outer mounting base. The rotatory carrier is securely screwed onto a track frame, which has a hollow sliding slot on the center of the bended body thereof. The track frame is securely positioned on the axially connecting base of the rotatory carrier via two axial plates that locate on the rearward of the track frame. The lamp holder is rotatably coupled with the rotatory carrier by two bolts. The bolts are mounted in the limited connection space between the lamp holder and the rotatory carrier. Besides, the lamp holder is shiftable along the sliding slot for adjusting the lighting angle within approximate 70 degrees. Consequently, the recessed lamp structure of the present invention has simplified components and is easy to practice.
