Abstract
The present invention provides an illumination module, and a display and a general lighting apparatus using the same. Said illumination module includes a plurality of light guiding strips arranged in juxtaposition with a predefined distance; a plurality of light sources, disposed on at least one end of said light guiding strips respectively for providing the light into said light guiding strips; and a plurality of light reflecting units, disposed between said light guiding strips for reflecting the light from said light guiding strips. The light reflecting units according to the present invention can guide the light from the sides of light guiding strips or other light not toward the right side of the illumination module back to the right side of the illumination module, and thus improving the light output efficiency and uniformity.
