20080253107 | LIGHT EMITTING MODULE - A light emitting module includes a transparent substrate and a plurality of light emitting diodes (LEDs). The transparent substrate has a first surface, a second surface disposed opposite to the first surface and a patterned conductive layer disposed on the first surface of the transparent substrate. The LEDs are disposed on a lateral side of the first surface and are electrically connected with the patterned conductive layer. Light outputted from the LEDs is guided by the transparent substrate and is outputted from the first surface or the second surface. | 10-16-2008 |
20090021935 | LIGHT-EMITTING MODULE, DIFFUSION UNIT AND DIFFUSION SHEET - A diffusion unit of a light-emitting module is disposed adjacent to at least one light source. The light source emits a light beam. The diffusion unit includes a first diffusion sheet and a second diffusion sheet. The thickness of the first diffusion sheet is less than 1 mm, and the thickness of the second diffusion sheet is also less than 1 mm. The second diffusion sheet is disposed adjacent to the first diffusion sheet. The light beam is directly emitted from the light source directly to the first diffusion sheet. A light-emitting module and a diffusion sheet are also disclosed. | 01-22-2009 |
20100085771 | LIGHT GUIDING PLATE - A light guiding plate includes a light guiding plate body and a plurality of total internal reflection destruction materials.
