| 20090080205 | LED LAMP HAVING HEAT DISSIPATION STRUCTURE - An LED lamp for lighting purpose includes a lamp base, a heat sink, a plurality of LED modules and a blower. The lamp base encloses an inner space and defines a plurality of vents therein. The vents communicate the inner space with a surrounding atmosphere. The heat sink comprises a cylinder at a centre thereof. The cylinder has a through hole therein, which communicates with the inner space and vents of the lamp base and cooperates therewith to form an air passage. The LED modules are attached to a periphery of the heat sink. The blower generates an airflow circulating through the air passage to thereby dissipate heat generated by the LED modules. | 03-26-2009 |
| 20100014287 | ILLUMINATING DEVICE WITH HEAT DISSIPATING ELEMENT - An exemplary illuminating device includes a circuit board, a plurality of light sources, a thermal interface material, and a plurality of stretched resilient elements. The circuit board has a first surface and a second surface at an opposite side of the circuit board to the first surface. The plurality of light sources is electrically mounted on the first surface of the circuit board. The heat dissipating device is attached on the second surface of the circuit board. The thermal interface material is applied between the second surface of the circuit board and the heat dissipating device. The plurality of resilient elements are configured for connecting the circuit board with the heat dissipating device and providing a pulling force therebetween. | 01-21-2010 |
| 20100117113 | LIGHT EMITTING DIODE AND LIGHT SOURCE MODULE HAVING SAME - An exemplary light emitting diode includes a substrate, a metal material and a light emitting diode chip. The substrate has a first surface and a first through hole defined in the first surface. The first through hole is filled with the metal material. The light emitting diode chip is mounted on the first surface contacting the metal material in the first through hole. | 05-13-2010 |
| 20100151122 | METHOD FOR FORMING PHOSPHOR COATING - An exemplary method for forming phosphor coating includes: providing a substrate; forming a first hydrophilic film on the substrate, the first film being soluble in water; forming a second lipophilic film on the first film, the second film comprised of a phosphor material; submerging the substrate having the first film and the second film formed thereon into water, so that the first film is dissolved in water and the second film is floated on surface of the water; and dipping a light source into the second film to forming a phosphor coating on the light source. | 06-17-2010 |
| 20100163097 | SOLAR CELL MODULE WITH CONCAVITY SURFACE - An exemplary solar cell module includes a main body, a number of solar cells, and a reflective layer. The main body defines a concavity surface defined thereon. The solar cells are positioned at the concavity surface and generally symmetrically arranged with respect to a central axis of the concavity surface, configured for converting sunlight to electricity. The reflective layer is positioned on the concavity surface, with the solar cells exposed to an exterior of the main body corresponding to the concavity surface. | 07-01-2010 |
| 20100290223 | LIGHT SOURCE HOLDER AND BULB USING SAME - A light source holder includes a spherical surface and a number of recessed portions. The recessed portions are defined in the spherical surface and arranged substantially evenly over the spherical surface. Each of the recessed portions comprises a plurality of inner surfaces. The inner surface of each recessed portion comprises a bottom surface and a lateral reflective surface. The bottom surface is capable of having a solid-state light source arranged thereon. The lateral reflective surface is adjacent to the bottom surface and configured for reflecting light emitted from the solid-state light source and outputting the light from the recessed portion. | 11-18-2010 |
| 20100327750 | LED ILLUMINATING APPARATUS - An LED illuminating apparatus includes a lampshade, a cover engaged with the lampshade, a heat dissipation module received in a hollow tube cooperatively formed by the engaged lampshade and cover, a light source engaged on the heat dissipation module, and two connectors secured at opposite ends of the lampshade and the cover. The lampshade defines a plurality of vents therein. The light source faces the cover and light emitted from the light source radiates out of the LED illuminating apparatus through the cover. | 12-30-2010 |
| 20110291542 | LED BULB - An LED bulb includes a connector for electrically connecting with a power supply, a heat sink disposed on the connector, and a plurality of LEDs mounted the heat sink. The heat sink includes a base, a tube extending downwardly from a first face of the base, and a plurality of fins extending outwardly from an outer circumference of the tube. The LEDs are attached on a second face of the base. The base defines a plurality of through tunnels extending through the base from the first face to the second face of the base. | 12-01-2011 |
