Abstract
An LED module includes an LED, a light guiding plate and a lens. The light guiding plate includes a light incident face confronting the LED, a light diffusion face and a light emerging face. The lens includes an aspheric light incident face and an aspheric light emerging face opposite to the aspheric light incident face. Light emitted from the LED is diffused by the light guiding plate and diverged by the lens to have a wide illumination area.
