Patent number: 7993046Abstract: A flexible light-emitting apparatus including a side light-emitting flexible light guide rod, two light emitting diodes, and two lenses is provided. The side light-emitting flexible light guide rod has a first end, a second end opposite to the first end, and a light-emitting surface connecting the first and the second ends. The LEDs are respectively disposed beside the first end and the second end and adapted for emitting light beams toward the side light-emitting flexible light guide rod, respectively. One of the lenses is located between the first end and the LED disposed beside the first end, and the other lens is located between the second end and the LED disposed beside the second end. Each of the light beams enters the side light-emitting flexible light guide rod through the corresponding lens and is transmitted to the outside of the side light-emitting flexible light guide rod through the light-emitting surface.Type: GrantFiled: April 21, 2009Date of Patent: August 9, 2011Assignee: United Lighting Opto-Electronic Inc.Inventors: Chiang-Ching Wang, Chi-Wen Kuo, Jun-Zhou Chen, Chien-Hua Wu, Tsung-Hsien Chou, Chia-Hung Hsu

Publication number: 20100085730Abstract: An illuminating device for machining tools is disclosed. A machining tool is installed with an illuminating device that uses a single LED prepared using the multi chip single module technique to provide high-power light. This elongates the lifetime of the illuminating device and has the advantages of power-saving and low temperature. The light thus produced does not have UV and IR components. In addition to no radiation injury to human bodies, the invention also avoids overlapped shadows in the case of multiple LED sources. Such a design of the cold and single light source can effectively bad influences on the precision of objects 31 being processed.Type: ApplicationFiled: October 7, 2008Publication date: April 8, 2010Applicants: Avex-SG Technology Inc., Leaps & Bounds Technology Co., LTD., Shyh Tah ChernInventors: Kimble J.

Publication number: 20090052127Abstract: This invention provides an electrical appliance housing comprising a main body and a lid. At least one magnetic controlling assembly is provided on the housing, comprising a sliding key that shifts in a sliding groove. The sliding key further includes a pair of controlling magnets with opposing magnetic polarity. An actuating magnet is installed inside of the housing and corresponds to a specific controlling key of the electrical appliance. Shifting the sliding key will produce a magnetic force relative to the actuating magnet, and this force in turn activates the controlling key of the electrical appliance. In addition, at least one functional device is installed on the lid that corresponds to the specific functional key of the electrical appliance, comprising a pair of blind holes situated so to correspond with one another. An actuating magnet is installed in the inner hole and a controlling magnet is fixed on the bottom of the sliding key which has the same magnetic polarity with said actuating magnet.Type: ApplicationFiled: August 25, 2007Publication date: February 26, 2009Inventor: CHI-WEN KUO
