20090091946 | Light-guiding structure - A light-guiding structure includes a light-guiding plate, and an LED set matched with the light-guiding plate. The characteristic is that the light-guiding plate has a light-entering surface, and there are a plurality of ditches on the light-entering surface. A light-entering interface is formed between two adjacent ditches. The LED set corresponds to the light-entering surface of the light-guiding plate, and each of the LEDs of the LED set corresponds to one light-entering interface. By utilizing the light-entering interface and the ditches, the light is uniformly spread. The light is uniformly spread at the light-entering surface of the light-guiding plate so that the bright point does not occur. The light is uniformly emitted from the light-emitting surface and the illumination is enhanced. | 04-09-2009 |
20110249448 | LIGHT-GUIDING MODULE - A light-guiding module includes a casing, a light-guiding body, a light source, and a light-abating element. The casing has an accommodating space and a light-emerging surface. The light-guiding body is received in the accommodating space of the casing and has a light-entering surface and a light-emerging surface. The light-emerging surface is located to correspond to the light-emerging surface of the casing. The light source is located to correspond to the light-entering surface of the light-guiding body. The light-abating element is located to correspond to the light-emerging surface of the light-guiding body, and the light-abating element may be located close to the light source. The light-abating element may be provided at a position which the light-guiding body is close to the light source, thereby making the light emerging from the light-guiding body to become more uniform and thus overcoming the problem that the brightness of light is uneven. | 10-13-2011 |
