Researchers Submit Patent Application, "LED Illuminating Device", for Approval

June 18, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventor Lin, Tai-Chiang (Surrey, CA), filed on November 26, 2012, was made available online on June 5, 2014.

No assignee for this patent application has been made.

News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to an LED illuminating device and, more particularly, to an LED illuminating device providing a larger illumination area and a heat dissipating effect.

"Conventional illuminating light sources including bulbs, fluorescent lamps or mercury lamps have disadvantages, such as poor illumination efficiency, large power consumption, liability to damage, and short service lives.

"Light-emitting diode (LED) devices provide advantages of excellent illumination efficiency, low power consumption, and long service lives. However, the high temperature resulting from conversion between electricity and light must be dissipated to avoid disadvantages including reduced illuminating effect, shortened service lives and luminous depreciation.

"However, the LEDs are mounted in a small area of the currently available LED devices and, thus, provide limited illumination. Furthermore, the high temperature generated by the LEDs can not be conducted rapidly, resulting in poor heat dissipating effect and a low heat dissipating speed, causing the above disadvantages."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "An objective of the present invention is to provide an LED illuminating device providing a larger illumination area, enhanced illumination effect, and a longer service life while providing excellent heat dissipating efficiency and a high heat dissipating speed.

"An LED illuminating device according to the present invention includes a heat-dissipating lamp seat having a top side and a bottom side opposite to the top side. A plurality of fins is provided on the top side. The bottom side includes a recessed portion. A fixing seat is mounted to the top side of the heat-dissipating lamp seat. The fixing seat includes a channel having two ends. First and second end caps are mounted to the ends of the channel. The fixing seat has a width smaller than a width of the heat-dissipating lamp seat. A power supply unit is mounted in the channel of the fixing seat. The power supply unit includes a substrate, a power supply fixed to the substrate, and a connecting assembly fixed to the substrate and electrically connected to the power supply. A light-emitting diode (LED) assembly is fixed in the recessed portion of the heat-dissipating lamp seat. The LED assembly includes a plurality of circuit boards and a power cord. A plurality of LEDs is electrically connected to a bottom face of each of the plurality of circuit boards and electrically connected to the connecting assembly. A diffuser is fixed to the bottom side of the heat-dissipating lamp seat and covers the LED lamp assembly. Light beams generated by each of the plurality of LEDs are adapted to transmit downward through the diffuser.

"Preferably, the fixing seat includes a bottom mounted to an intermediate portion of the top side of the heat-dissipating lamp seat, and the width of the heat-dissipating lamp seat is three to five times of the width of the fixing seat.

"Preferably, the bottom of the fixing seat is connected by a connecting rib to the intermediate portion of the top side of the heat-dissipating lamp seat.

"Preferably, the heat-dissipating lamp seat, the plurality of fins, and the fixing seat have an identical length.

"Preferably, the power supply includes an input end connected to a power wire. The heat-dissipating lamp seat includes a through-hole in communication with the channel. The power cord of the LED assembly is extended through the through-hole into the channel and electrically connected to the connecting assembly.

"Preferably, the channel of the fixing seat includes two lateral grooves, and the substrate includes two lateral edges received in the lateral grooves.

"Preferably, the substrate includes an end having a tab with at least one fixing hole. The first end cap includes at least one through-hole. At least one bolt extends through the at least one through-hole into the at least one fixing hole of the tab.

"Preferably, a frame is mounted around the diffuser and includes a plurality of through-holes. The bottom side of the heat-dissipating lamp seat includes a plurality of screw holes. A bolt is extended through each of a plurality of through-holes of the frame into one of the plurality of screw holes. The frame includes an inner periphery having four sides. A gasket is mounted to each of the four sides of the inner periphery of the frame. Each gasket includes an engagement groove receiving one of the four sides of the diffuser.

"The present invention will become clearer in light of the following detailed description of illustrative embodiments of this invention described in connection with the drawings.

DESCRIPTION OF THE DRAWINGS
