Abstract

A light source module including an optical film and at least one light source unit is provided. The light source unit and the optical film enclose a space. The light source unit includes a reflecting device, at least one light bar, and a collimated unit. The reflecting device is disposed under the optical film. The light bar includes a plurality of light-emitting elements arranged along a third direction. The collimated unit extends along a direction parallel to the third direction and includes an upper reflective portion and a lower reflective portion. A shortest distance between one end of the lower reflective portion located adjacent to the reflecting device and the optical axis of the light-emitting elements along a second direction is defined as a first half light-emitting width, which is gradually increased along the third direction from a center portion of the collimated unit towards two sides thereof.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of China application serial no. 201410180679.7, filed on Apr. 30, 2014. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND[0002]1. Technical Field[0003]The invention relates to a light source module, and particularly relates to a light source module adapted for a display device.[0004]2. Related Art[0005]In recent years, along with enhancement of light-emitting efficiency and prolonging of service life of light-emitting diodes (LEDs), and due to characteristics and advantages of low power consumption, low pollution, high efficiency, high response speed, small volume, light weight and capable of being disposed on various surfaces, the LEDs are widely applied in various optical fields. Generally, the LEDs can be applied to various illumination devices and various planar displays in daily life, for exampl...
