| 20100060132 | LED ILLUMINATING DEVICE - An LED illuminating device includes an optical part having a light source therein, an electrical part and a heat dissipation part. The electrical part includes a rear shell and a circuit board electrically connecting with the light source. The heat dissipation part includes a hollow front shell having a rear end secured with the rear shell, a heat sink and a cooling fan arranged in the front shell. The front shell defines a plurality of first and second air holes. The heat sink includes a solid base and a plurality of fins. The light source is thermally connected with the base. An airflow produced by the cooling fan is introduced into the front shell via the first air holes. The airflow flows then towards the heat sink and finally flows out of the front shell via the second air holes. | 03-11-2010 |
| 20100264799 | LED LAMP - An LED lamp includes a hollow lamp housing, a front optical part, a rear electrical part provided with a circuit board, and a middle heat dissipation part. The heat dissipation part includes a heat sink, and a mounting seat located in front of and thermally connected to the heat sink. The lamp housing defines a plurality of air exchanging holes therein. The mounting seat is in the form of a polyhedron, and has a polyhedral rear end surface and a plurality of heat absorbing surface. The optical part includes a plurality of light sources respectively arranged on the heat absorbing surfaces, a light reflector located between the heat sink and the light sources, and an optical lens located in front of the light reflector. The heat absorbing surfaces extend forwardly from a peripheral edge of the rear end surface towards the optical lens and facing the optical lens. | 10-21-2010 |
| 20110044042 | LED ILLUMINATION DEVICE - An LED illumination device includes a heat dissipation part, an optical part and an electric part. The optical part includes an LED module attached on the heat dissipation part and an envelope mounted on the heat dissipation part and covering the LED module. The electric part includes a casing and a lamp cap. The casing is cup-shaped. The lamp cap includes a sleeve electrode and a spring electrode attached at a bottom of the sleeve electrode. The sleeve electrode and the spring electrode electrically power the LED module. One end of the casing along an axis thereof is mounted on bottom ends of the heat dissipation part and the optical part. The sleeve electrode is disposed around the other end of the casing. The spring electrode is resiliently deformable along an axis of the sleeve electrode. | 02-24-2011 |

| 20090208204 | PASSIVE OPTICAL NETWORK SYSTEM - A passive optical network system according to the present invention includes an optical network unit and an optical line terminal connected to a plurality of optical network units. The optical line terminal has: an interface which receives from the optical network unit, a logical link assignment request message containing a communication priority for deciding a priority of a communication flow between a source terminal and a destination terminal, from the destination; and a control unit which assigns a logical link identifier for identifying a communication flow to the logical link assignment request message received from the interface and controls the interface so as to communicate with the optical network unit by using the communication priority. | 08-20-2009 |
| 20100119227 | Storage function method and apparatus in a passive optical network - A method and an apparatus for implementing a storage function in a passive optical network (PON) system. On the basis of a LINK ID held by the data, data requiring storage, e.g. data making exclusive use of a wide bandwidth such as audiovisual data and large-volume data packages, are determined among all the data sent to an optical network unit. These data requiring storage are stored in a storage device installed in the optical network unit. In case the user requests data stored in the storage device, the stored data are transferred directly to the user, without any need to request and send these data for the second time via an IPTV server and the core network. It is possible to avoid duplicate transfers of data, and in particular to avoid duplicate transfers of data making exclusive use of a comparatively wide bandwidth such as audiovisual data and large-volume data packages, to improve the utilization factor of the downlink bandwidth, and to reduce flow congestion and data delays. | 05-13-2010 |
