A backlit LED panel light is a low profile troffer light which employes a planar LED module to pump light directly through the optical diffuser. This configuration is designed to address the downsides of edge-lit devices. The proven benefits of edge-lit LED panel lights are well-known. These surface emission devices are capable of delivering soft, homogeneous illumination across the entire surface of the light emission surface (LES). The edge-lit technology uses a light guide panel (LGP) to uniformly distribute and direct downward the light emitted by the side-firing LEDs. While the revolutionary edge-lit LED architecture enables an extremely uniform light distribution and low profile design, the use of the LGP poses is a reliability issue.
