The retaining thread is passable through the through hole of the mounting arm by threadingly passing the retaining thread through the inner thread of the through hole of the mounting arm whereupon the fastener remains preassembled in the through hole. | 09-29-2011 |
20110235280 | HEAT DISSIPATION APPARATUS AND ELECTRONIC ASSEMBLY WITH SAME - A heat dissipation apparatus includes a heat sink and fasteners. The heat sink defines a plurality of through holes therein. An inner thread is formed on an inner surface of each through hole. Each fastener includes a bolt and a spring around the bolt. The bolt includes a main post, a cap formed on a top of the main post, and a engaging portion formed on a bottom of the main post. A retaining thread is formed on an outer surface of the main post near the engaging portion. The retaining thread matches the inner thread of the through hole. The retaining thread of the main post is configured to pass through the through hole by threading the retaining thread though the inner thread of the through hole. After the retaining thread has passed through the through hole, the retaining thread abuts a bottom surface of the heat sink. | 09-29-2011 |
20110234113 | LED LAMP - An LED lamp includes two LED modules and a control module. The LED modules emit lights with different color temperatures. The lights are mixed in the LED lamp and form an output light with another color temperature. The control module controls the brightness levels of the lights emitted from the two LED modules to thereby control the color temperature of the output light. | 09-29-2011 |
20110232874 | HEAT DISSIPATION APPARATUS WITH HEAT PIPE - A heat dissipation apparatus includes an evaporator receiving heat from a heat source, a condenser releasing the heat of the heat source, and a pipeline inter connecting the evaporator and the condenser. The condenser defines a flat rectangular chamber therein. A working fluid is contained in the evaporator. The working fluid vaporizes upon receiving the heat of the heat source. The pipeline conducts the vaporized working fluid from the evaporator to the condenser. The vaporized working fluid condenses upon releasing the heat in the chamber. | 09-29-2011 |
20110228523 | SOLAR LED LAMP - A solar LED lamp includes a housing, a light emitting module, a solar panel, and a light collective member. A circumference of the housing defines a plurality of windows. A light emitting module is received in the housing. Light rays emitted by the emitting module travel out of the housing via the plurality of windows. The solar panel absorbs solar energy and transfers the solar energy into electrical energy for the light emitting module. The light collective member is located over the solar panel and directs sunlight toward the solar panel. | 09-22-2011 |
