| 20100271821 | REFLECTOR AND LED LIGHT-EMITTING UNIT USING THE SAME - An LED light-emitting unit comprises an LED element having an optical axis and a reflector covering the LED element. The reflector comprises a light-reflecting unit recessed downwardly from a top surface of a top wall of the reflector and located corresponding to the LED element. The light-reflecting unit has a reflecting face comprising two curved faces intersecting with each other at two lines. The curved faces have axes intersecting with each other. A distance between two intersecting points of the two lines with a cross section of the reflector which is parallel to the top surface of the top wall of the reflector is larger than that between any other two intersecting points of the reflecting face intersecting with the cross section of the reflector. | 10-28-2010 |
| 20100271784 | HEAT SINK ASSEMBLY HAVING A CLIP - A heat sink assembly includes a heat sink adapted for thermally contacting an electronic component of a printed circuit board, and a clip pressing the heat sink and engaging with the printed circuit board. The clip includes a pressing portion pressing the heat sink, two arms extending slantwise and upwardly from opposite ends of the pressing portion, two connecting portions extending outwardly from the two arms, two securing portions engaging with the printed circuit board, and two operating portions. When the two operating portion are operated, the connecting portions are rotated and the securing portions rotate with the connecting portions to engage with the printed circuit board. | 10-28-2010 |
