Abstract： |
A surface light source module based on a light emitting diode characterizes in including a light emitting diode and a light plate diffusing the light emitted from the diode to a main exit surface distributed with several extended light emitting leading structures on it projecting over the main exit surface and approximately the arc state, said arc is any kind of line, a line or a curve taking the projecting image point of the diode light source on the main exit surface as the approximate center. The main surface facing the liquid crystal layer in a LCD or the plane for illumination in an illuminator is the main exit surface. |
