The invention provides a light driving plate and panel illuminating apparatus. The light driving plate has up and down two layer structure, the down layer comprises at least one light incidence panel used to receive the light from the light source and a back-light panel on the bottom panel; the up layer comprises a base plate with a light exit panel on the surface of the upper panel and the bump arrange-formed on the bottom panel near the down layer of the light driving plate on the base plate. The panel illuminating apparatus adopts the light driving plate to evenly eject the light from the light exit panel of the light driving plate. It arranges the ladder structure on the up layer bottom panel of the light driving plate which can control the light exit angle of the light exit panel. |
