Abstract
A large-angle rotating recessed lamp comprises a lamp seat and a lamp cap which is rotatablely arranged inside the lamp seat. The large-angle rotating recessed lamp is characterized in that the lamp seat is provided with a concave spherical surface, the bottom of the lamp cap is a convex spherical surface which is rotatablely matched with the concave spherical surface of the lamp seat, and a sliding groove is arranged on the concave spherical surface along the radial direction. A slide block device is placed on the bottom of the lamp cap, and the slide block device is capable of moving along the sliding groove and achieving the rotatable positioning. Compared with the prior art, the large-angle rotating recessed lamp has the advantages that the cooperation between the sliding groove on the lamp seat and the slide block device on the lamp cap enables the lamp cap to be pulled outwards to the outside of a rotating spherical surface of the lamp seat. The large-angle rotating recessed lamp is simple in structure and convenient to operate. On the premise that the insert depth of the lamp seat is not changed, the rotating angle of the lamp cap in a large range is achieved, and good lighting effects and a large irradiation range can be obtained.
