Abstract

A LED sunken lamp includes a case and a lighting assembly. The case includes a lamp shade and a case seat. The lamp shade is wedged in the case seat. The lighting assembly also is wedged in the case seat and includes at least a LED lamp and a circuit board that are electrically connected. The case seat can be disassembled to facilitate wedging of the lamp shade and the lighting assembly in the case seat. The case seat also has a plurality of radiation fins to disperse heat energy generated by the LED lamp when in use to increase the life span of the LED lamp.

Claims

1. A LED sunken lamp comprising a case and a lighting assembly, the case including a lamp shade and a case seat, the lighting assembly including at least a LED lamp and a circuit board that are electrically connected;

wherein the case seat is allowed to be disassembled and has a housing groove and a plurality of heating dissipating fins, the lamp shade and the lighting assembly being wedged in the housing groove and installed on the case seat.

2. The LED sunken lamp of claim 1, wherein the case seat is coupled with a relay assembly which has a second thread structure, the case seat having a first thread structure corresponding to and engageable with the second thread structure.

3. The LED sunken lamp of claim 2, wherein the relay assembly, the LED lamp and the circuit board are electrically connected.

4. The LED sunken lamp of claim 1, wherein the case seat has corresponding bolting structures to be fastened through a bolt.
