Abstract: An embedded lamp comprises a base, an embedded bracket, a lamp socket, and a decorative plate, wherein a flange is formed on the internal periphery of a rotatable bracket of the embedded bracket for coupling with the decorative plate. A protrudent ring having at least a pair of buckling means having a pair of protrudent elastic buckles is mounted on the internal periphery of the decorative plate. When the decorative plate is inserted into the rotatable bracket, the protrudent elastic buckles are bounded to buckle the flange and to be positioned thereon. By means of the above-mentioned structure, the decorative plates with different internal diameter dimensions can be replaced with one another according to the diameter dimensions of various light bulbs without detaching the base and the embedded bracket. Accordingly, it facilitates the replacement of the light bulbs without need of high maintenance technique.

Abstract: A safety switch control structure for a lamp device, including outer mask shell for lamp device, lamp mask, fixing rack and interlock, wherein the fixing rack installed underneath the lamp device outer mask shell is equipped with interlock, the interlock is underneath the socket, above the interlock is installed with a spring piece, and a switch is underneath the spring piece, and the spring piece lock of interlock is underneath one of the spring clips; furthermore, the spring piece protruding part is underneath the clip part of the spring clip end. When the lamp mask is combined with the socket, the open spring clip on the socket lets the interlock contact socket and forms a conducting channel. When the lamp mask is separated from the socket, the spring clip goes back to its original shape and no longer contacts the spring piece of the interlock; no electricity is passing.
