Abstract: A heat sink structure for light-emitting diode (LED) based streetlamps is disclosed, which comprises an upper cover, on which heat sink fins are integrally formed, and a lower cover. The heat energy generated by the LEDs mounted within the upper cover and the lower cover can be removed through the heat sink fins, achieving the effect of rapid removal of the heat energy.

Abstract: Disclosed is a LCD back light module structure comprising one or more than one LED arrayed along an electric conducting stick which being equipped with conductor blades on its surface. The conductor blade is used for connecting the conducting stick to a driving circuit. A blind hole is formed on the conducting stick and the light spot of the Led die is buried in the blind hold and the electric connection is extended from the light spot to the adjacent two conductor blades. After being completed connection for each LED die, the epoxy resin is infused around the blind hole to form a transparent lens. The high crowned configuration of the lens enables the LED to uniformly emit the light therefrom therefore each LED forms a uniformly brilliant lighting surface on the LCD back light module structure.

Abstract: A tapered prism illumination apparatus for LCD backlight consists of an LCD, a plurality of LEDs and a heat dissipation base. The plurality of LEDs consists of high power LEDs mounted in the back of the LCD, wherein each of the LEDs includes a light emitting point that is packaged exteriorly with a transparent covering body and, on the light emitting path of the LED, a tapered prism is disposed. In the periphery of the LED a thermally conducting substrate is disposed, while the heat dissipation base is mounted in the rear of the LEDs and has reflecting faces in the periphery of each of the LEDs. When light is generated at the light emitting point, it can be projected onto the tapered prism, by which it is bent by 90°, and then projected onto the LCD via the reflecting faces. The heat generated by the high power LEDs is conducted by the thermally conducting substrate to the heat dissipation base to be removed.

Abstract: A LED decorative lighting structure comprises a plurality of LEDS. Each LED has two electric conductor blades which being directly made by cutting down from a strip of the same material. Each of the two conductor blades is equipped with a terminal which further includes a holding strip and an electric conducting strip. The holding strip is for fixing an outer insulation sheath of a conductor by pressing on it; while the conducting strip is for fixing and making connection with the metallic stranded core wires of the conductor. The holding strips and the electric conducting strips in both conductor blades are disposed in different height with each other so as to avoid shortcircuiting by accidental contact. The plurality of LED constructed as such can be arranged in series/parallel connection thereby forming a desired configuration of the LED decorative lighting structure according to the present invention.

Abstract: A lighting and flashing Christmas tree structure apparatus employs a low power control circuit to control the flashing sequence of LED light strings, capable of randomly altering distribution of the light strings with free choice of colors. A plug-free magnetic power system supplies electrical power to a cuboidal body where each of the four sides thereon has an electrical power receptacle free for user selection. With a LED device controller, a magnificent blinking is emitting from the LED light source to delight Christmas atmosphere. The electrical power offered by the present invention is limited below 24 V, which is within the safety range of the electrical properties code for body contact, therefore being free of safety concerns.
