Abstract
A light source module includes a light guide plate, a reflecting film, and a plurality of edge-type light emitting diode (LED) units. Grooves are defined in a lower surface of the light guide plate. The reflecting film is below the lower surface and covers the entire lower surface and the grooves. An air gap is defined between the reflecting film and the lower surface. The edge-type LED units are located in the grooves. Each edge-type LED unit includes an LED chip, a wavelength converting layer, and a light reflecting layer. Light emitted is converted by the wavelength converting layer, reflected towards sidewalls of the wavelength converting layer, and transmitted to the lower surface. The reflecting film reflects light that enters the air gap towards an upper surface of the light guide plate, enabling uniform emission of light from the upper surface.
