20090284968 | LIGHT EMITTING DIODE LAMP - A light emitting diode (LED) lamp includes a lampshade, a light guide pole and a plurality of LEDs. The light guide pole is of light permeable material and received in the lampshade. A plurality of irregular elements is formed on an outer surface of the light guide pole. A distribution density of the irregular elements decreases gradually from two ends of the light guide pole towards a middle of the light guide pole. The LEDs are mounted at the two ends of the light guide pole. Light emitted by the light emitting diodes falls incident into the light guide pole and exits the light guide pole from the outer surface thereof. | 11-19-2009 |
20090294786 | LIGHT EMITTING DIODE DEVICE - A light emitting diode device includes a substrate, a plurality of light emitting diode chips mounted on the substrate and arranged in a plurality of lines and a frame located on the substrate. The frame includes a plurality of first plates each extending along a first direction of the substrate, a plurality of second plates each extending along a second direction of the substrate and a plurality of reflecting plates. The first plates and the second plates cooperatively form a plurality of receiving rooms for receiving the light emitting diode chips therein. Each reflecting plate is located above a corresponding line of light emitting diode chips and inclined with respect to the substrate. | 12-03-2009 |
20100139888 | HEAT SPREADER AND HEAT DISSIPATION DEVICE USING SAME - A heat dissipation fan includes a fan frame, a bearing assembly, a stator and a rotor. The fan frame includes a base and a central tube. The central tube includes an open top end and an open bottom end. The base defines a receiving concave at a bottom surface thereof. The receiving concave communicates with the central hole. A top wall is formed by the base over the concave. A sidewall is formed between the top wall and the bottom surface of the base and surrounds the concave. A plurality of first locking units extend from the top wall into the receiving concave. The bearing assembly includes an oil sealing cover for sealing the open bottom end of the central tube. The oil sealing cover includes a plurality of second locking units which are detachably interlocked with the first locking units to mount the oil sealing cover to the base. | 06-10-2010 |
20100157605 | LIGHT EMITTING DIODE LAMP - A light emitting diode lamp includes a lampshade and a light source. The lampshade is a portion of a hollow ellipsoid with one focus of the ellipsoid located therein. The lampshade is symmetric to a major axis of the ellipsoid. The lampshade has a vertex located on the major axis and defines a light extraction opening at one end thereof opposite to the vertex. A reflecting layer is formed on an inner surface of the lampshade. The light source is received in the lampshade and localized at the one focus of the ellipsoid. The light source includes a plurality of light emitting diodes facing the inner surface of the lampshade and the light extraction opening, respectively. | 06-24-2010 |
