| 20100253199 | LED LIGHTING TUBE - The LED lighting tube of the present invention utilizes a tubular heat dispersing structure and arranges the LED module in a light-tube manner, characterized in that the tubular heat dispersing structure can produce the airflow to increase the heat dispersing effect, and also, the closed structure thereof can prevent dust accumulation, so as to protect the LED module and extend the lifetime of the LED module. Besides, the present invention also employs plural electric controllers to control LED bulbs in multiple LED modules so as to achieve a section control of LED bulbs of different positions or different colors and satisfy multiple illumination requirements. | 10-07-2010 |
| 20090213583 | LED Module - The present invention discloses an LED (Light Emitting Diode) module, which comprises: a plurality of LED lamps, baseplates, heat-conduction blocks, heat-conduction elements, and fixing elements. The LED lamp has an electrode plate on one side and an LED on the other side. One face of the electrode plate has two electrodes respectively arranged in two edges. A protection ring annularly surrounds the LED. The baseplate is a printed circuit board having a plurality of through-holes and cascade circuits on one side. The heat-conduction block is a metal block having an appropriate thickness and a high thermal conductivity and is attached to one side of the electrode plate to dissipate the heat generated by the LED lamps. The heat-conduction block has a plurality of fixing holes. The fixing elements are fastened into the fixing holes to join together the heat-conduction block and the baseplate. The heat-conduction element is a heat-conduction body attached to the other side of the heat-conduction block. | 08-27-2009 |
