20120091894 | LED DRIVING DEVICE - An LED (Light-Emitting Diode) driving device is electrically connectable with an alternating current (AC) power supply and includes an electronic converter received in the driving device and a first connector, which is formed on an end of the driving device to connect with the AC power supply and in electrical connection with the electronic converter, and a second connector, which is formed on another end of the driving device for connection with an LED lighting module. When the first connector is set in electrical connection with the AC power supply, the above arrangement allows for conversion of electrical current and voltage to those applicable to an LED lighting module within 10 W rating. | 04-19-2012 |
20120092862 | STRUCTURE OF LIGHT-EMITTING DIODE (LED) HAVING HIGH COLOR RENDERING INDEX - Disclosed is a structure of light-emitting diode (LED) having high color rendering index, including a substrate on which at least one light emission element, at least one red light emission element, and at least one green light emission element are mounted. The light emission element emits blue light that is also applied to excite a fluorescent powder coated outside the light emission element to generate white light, which when mixed with red and green lights from the red and green light emission elements, form a light source of improved color rendering property. With the addition of the red and green light emission elements, the light projecting from the LED structure provides a color performance close to the natural light, allowing for perfect reproduction of the original color of an object and thereby improving conformableness and coordination of human perception without causing any lose of color genuineness of an object. | 04-19-2012 |

20150300585 | LED LAMP - An LED lamp is connected to a pair of connecting elements and includes at least one lamp tube and two end caps. One end cap includes a power supply element and is electrically connected to an LED module, and the other end cap is connected to the lamp tube and includes a power conversion element. The end cap has an electric wire and a plug connected to the power supply element through the electric wire and connected to a socket for power supply. The lamp tube has a backlight surface, a light exit surface, and first latch portions disposed at both ends of the lamp tube, and the two end caps have at least one second latch portion and a fixing portion with a first through hole each, so that the connecting elements can be fixed to the two end caps through the first through holes. | 10-22-2015 |

20120274486 | HUFFMAN DECODER AND DECODING METHOD THEREOF - A Huffman decoder includes a storage module, a receiving module, and a determining module. The storage module stores a target path corresponding to a rare path. The receiving module receives a codeword in a source data stream and acquires corresponding path data for the codeword. The determining module compares the path data and the target path, and determines the codeword as the rare code when the path data and the target path are the same. | 11-01-2012 |
