20120320591 | LIGHT BULB - The instant disclosure relates to a light bulb, which includes a base, a conducting cap arranged on one end of the base, a heat-dissipating member disposed on the opposite end of the base, and a lamp cover. The heat-dissipating member has a wedged structure, and a plurality of inclined surfaces are formed adjacently thereon. A plurality of LEDs is disposed on the inclined surfaces, and the lamp cover is arranged over the wedged structure and the LEDs. The instant disclosure uses the LEDs to replace tungsten filament as the light sources, and arranging the LEDs on the wedged structure of the heat-dissipating member. Thereby, the light bulb can have higher heat-dissipating rate. | 12-20-2012 |

20110303143 | METHOD OF MANUFACTURING CRYSTALLINE SILICON INGOT - An approach is provided for a method to manufacture a crystalline silicon ingot. The method comprises providing a mold formed for melting and cooling a silicon feedstock by using a directional solidification process, disposing a barrier layer inside the mold, disposing one or more silicon crystal seeds on the barrier layer, loading the silicon feedstock on the silicon crystal seeds, heating the mold to obtain a silicon melt, and cooling the mold by the directional solidification process to solidify the silicon melt into a silicon ingot. The mold is heated until the silicon feedstock is fully melted and the silicon crystal seeds are at least partially melted. | 12-15-2011 |
