Description of the Invention: [Technical Field] The present invention relates to a light homogenizer and a backlight module including the same, particularly a modularized homogenizer and a backlight including the same Module. [Prior Art] V Reference Figure h shows a top view of a conventional backlight module disclosed in U.S. Patent No. 2,5,5,259,195, Al, with the diffusion layer omitted. Referring to Figure 2', a cross-sectional view of Figure 1 is shown. The conventional backlight module includes a diffusion layer Φ (Diffuser) (not shown), a reflector (Refiect〇r) 1〇, and a plurality of Packaged Light Guide Blocks 20. The light guiding blocks 20 are arranged in an array and are fixed on the reflecting plate 1 ’. The light guiding blocks 20 are appropriately spaced from each other. Each of the light guiding blocks 2 includes a light guiding body 21, an accommodating space 22 and four LEDs 23, 24, 25, 26. The material of the light guiding body 21 is an acrylate resin which is permeable to light, and the light guiding body 21 has a cylindrical ring shape to form the accommodating space 22 therein. The accommodating space 22 is an air layer that houses the LEDs 23, Lu 24, 25, 26. The LED 23 is a red LED for emitting red light; the 'LED 24 is a green LED for emitting green light; the LED 25 is a *green LED' for emitting green light; The LED 26 is a blue LED for emitting blue light. With the above structure, the light emitted by the LEDs 23, 24, 25, 26 can be mixed into a white light in the air layer of the accommodating space 22 and then emitted outward. However, since the LEDs 23, 24, 25, 26 are naturally mixed in the air, the light mixing efficiency is not high, and the thickness of the conventional backlight module is not effectively reduced by 122427.doc 1364565; Knowing the number of LEDs required for the backlight module cannot be effectively reduced. 'It not only consumes electricity but also reduces manufacturing costs. Therefore, it is necessary to provide an innovative and progressive sentence detector and a backlight module including the same to solve the above problem.
