摘要：
A flat LED lighting device may include a flat LED light source (1) having a plurality of light emitting diodes (LED) devices (10), a diffuser (3) for scattering a light from the LED devices (10), a glare preventive member (5) for preventing as a side glare, and an intermediate layer provided between the diffuser (3) and the glare preventive member (5). The intermediary layer may have a different refractive index than the diffuser (3). The glare preventive member (5) may include a transparent plate (54) and a plurality of micro-lenses (52) on the transparent plate for changing a distribution of the light.
