Abstract: A panel lamp includes a lamp frame, light bars, an upper light diffusing plate, an upper light guiding plate, a lower light guiding plate, a lower light diffusing plate and a middle optical isolation element. The lamp frame includes at least three frame bars successively connected, each provided with an installation groove. Each installation groove is internally provided with one lamp bar, each light bar is provided with an upper lamp body and a lower lamp body. The upper light diffusing plate, upper light guiding plate, middle optical isolation element, lower light guiding plate and lower light diffusing plate are snap-fitted in the installation grooves. The upper lamp body faces a side edge of the upper light guiding plate, and the lower lamp body faces a side edge of the lower light guiding plate. The middle optical isolation element is between the upper lamp body and the lower lamp body.
