| 20110070098 | FAN CONTROL SYSTEM - The present invention relates to a fan control system. The fan control system includes a first micro controller, a second micro controller and a first logic circuit. The first micro controller provides at least one first control signal. The second micro controller is connected to the first micro controller. The second micro controller detects operational status of the first micro controller, and provides at least one second control signal. The first logic circuit receives the first control signal and the second control signal to process logic operation and to generate at least one driving signal to fan. The fan control system of the invention utilizes two micro controllers, when one of the two micro controllers malfunctions, the first logic circuit allows the other micro controller to continue proper operation of the fan, thereby preventing the problem of insufficient heat dissipation that results from malfunction of the single micro controller of a conventional fan control system. | 03-24-2011 |

| 20090052054 | LENS BARREL - A lens barrel includes a lens group having an optical axis associated therewith, a fixed barrel and a rotatable barrel receives the fixed barrel. The fixed barrel has the lens group received therein and has a plurality of projections extending radially from the outer surface of the fixed barrel. The rotatable barrel rotatable relative to the fixed barrel about the optical axis has an inner latching groove and a number of insertion cutouts. The latching groove is defined in the inner surface of the rotatable barrel. The insertion cutouts are defined in a distal edge of the rotatable barrel with the inner latching groove and communicating with the latching groove. The insertion cutouts is insertable in the insertion cutouts and can engage in the latching groove for preventing the rotatable barrel to move axially relative to the fixed barrel. | 02-26-2009 |

| 20080246185 | COMPOSITION OF LED FRAME BODY AND MANUFACTURING METHOD THEREOF - A lamp body is an enclosing structure that encloses a blue light-emitting crystal to form a LED structure. In a method of manufacturing frame body of the LED, resin, titanium, and fluorescent powder are mixed uniformly to constitute a composition of frame body, then the composing materials being placed into a mould for processing a thermally pressing procedure to thus form a frame body. By the blue light emitted from the blue light-emitting crystal, the fluorescent powder of the frame body may be excited to emit uniform yellow light, which may be further mixed with the blue light to become white light. | 10-09-2008 |
| 20080246397 | MANUFACTURING METHOD OF WHITE LIGHT LED AND STRUCTURE THEREOF - A manufacturing method of white light LED and a structure thereof include first, a substrate being prepared to be formed as a consecutively connected holder, on a first electrode of which non-conductive fluorescent glue is coated to form a fluorescent layer, on which a blue light chip is fixed; second, two conducting wires being welded onto the chip and electrically connected to both the first electrode and the second electrode of the holder respectively, finally, glue body encapsulating the holder, the fluorescent layer, the chip, and the two conducting wires to form a photic zone, over which a frame body encloses; furthermore, a window being formed on the frame body and provided for making the photic zone exposed. When blue light chip is excited to generate blue light, which will further excite the fluorescent layer to emit yellow light, then both blue light and yellow light will be dispersed through the photic zone to generate a uniform light source, which may output light longitudinally and collectively, making the output power promoted notably and the lightness enhanced significantly. | 10-09-2008 |
