Abstract
The present invention relates to a LED panel lighting device, comprising: a back framework, an assembled housing, at least two circuit layer, a plurality of LED chips, a light guide plate, a bottom reflective member, and an optical diffusion member, wherein the assembled housing is consisted of a plurality of housing edges, and the circuit layers are disposed in the housing edges via a thermal conductive and electric insulating member, so as to be disposed with the LED chips. In the present invention, it mainly disposes the circuit layers with the LED chips into the housing edges by the thermal conductive and electric insulating member, without using any MCPCBs. Therefore, comparing to the conventional LED panel lighting device, this LED panel lighting device would not produce any heat accumulation issue because the MCPCB does not used in this LED panel lighting device.
