The invention discloses an embedded LED panel lamp. The embedded LED panel lamp comprises an LED panel lamp body, two fixing mechanisms and a shielding plate, the two fixing mechanisms are correspondingly arranged at the upper ends of two corresponding border proximate matters of a frame of the LED panel lamp body, the frame of the LED panel lamp body is sleeved with the shielding plate connectedwith the two fixing mechanisms, the shielding plate is used for preventing a gap between the LED panel lamp body and a reserved installing hole in a ceiling, each fixing mechanism comprises a seat body, a clamping plate, an anti-segregation body, a threaded hole, a first sliding body, a sliding groove, an adjusting bolt, a fastening bolt, a second sliding body and a connecting base, and each seatbody is arranged at the upper end of the corresponding border proximate matter of the frame of the LED panel lamp body. Compared with the prior art, the embedded LED panel lamp is advantageous in thatdismounting and mounting can be convenient, site environmental pollution caused by welding is avoided, the fixing reliability is good, and the embedded LED panel lamp is suitable for ceilings with different thicknesses.
