A back-lit LED panel consists of an array of LEDs mounted on a horizontal plate and illuminated vertically downwards through a diffuser into the space to be illuminated. Back-lit LED panel lights are sometimes referred to as direct-lit panels.
The light from the matrix of LED chips in the back light LED panel only passes through the thickness of the diffusing material. The lower light loss in the backlit LED panel light luminaire means a higher lumen output.
