Abstract: The present invention discloses a backlight structure having embedded light emitting diodes (LEDs) and a fabrication method thereof. The backlight structure comprises a PCB having a plurality of arc-shaped pits and necessary circuitry implemented thereon; a nanometer-thick gold layer sputtered on surfaces of said PCB and said plurality of arc-shaped pits; and an LED die embedded in each one of said plurality of arc-shaped pits, wherein said LED die is fused and fixed to the center of said arc-shaped pit by high frequency wave; said LED die is covered with a phosphor molding compound made by mixing phosphor and silica gel; and each one of said plurality of arc-shaped pits and its neighboring portion of PCB is covered by a window layer formed by transparent silica gel.

Abstract: The background light module for LCD utilizes LED as its light source, a single light generating LED die is grouped in an arcuately shaped oval lens to form an LED light source unit, and several LED light source units constructed as such are combined to form a background light module on a support arm to illuminate the LCD so as to create a brilliant and comfortable lighting effect.

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: 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.
