20130200400 | PCB HAVING INDIVIDUAL REFLECTIVE STRUCTURE AND METHOD FOR MANUFACTURING LIGHT EMITTING DIODE PACKAGE USING THE SAME - A printed circuit board (PCB) having an individual reflective structure and a method for manufacturing a light emitting diode (LED) package using the same, which can prevent reabsorption of light between LED chips by providing an individual reflective structure between the LED chips when the LED package is configured using two or more LED chips. The PCB includes a PCB; a wiring pattern-forming material layer formed on the PCB with an insulating layer interposed therebetween; dams formed on the wiring pattern-forming layer around chip mounting areas of the PCB; and a light reabsorption prevention dam formed on the wiring pattern-forming material layer between the chip mounting areas where LED chips are mounted. | 08-08-2013 |
20130133932 | METAL PCB HAVING HOLE REFLECTIVE SURFACE AND METHOD FOR MANUFACTURING THE SAME - A metal printed circuit board (PCB) having a hole reflective surface and a method for manufacturing the same, in which a process of forming a reflective surface by performing surface treatment on a metal plate and a process of bonding a PCB having a hole are performed as a single process, thus simplifying the manufacturing process and increasing the applicability of a product. The metal PCB includes a metal plate having a first reflective surface formed on a chip bonding area by surface treatment; a PCB layer stacked on the metal plate and having a hole and a wiring pattern which are formed in the chip bonding area; a second reflective surface formed on the inner side of the hole of the PCB layer; and a dam formed around the hole on the PCB layer. | 05-30-2013 |
20130037830 | LIGHT EMITTING DIODE PACKAGE AND METHOD FOR MANUFACTURING THE SAME - A light emitting diode package includes a heat-dissipating substrate including a reflective groove having a lower bottom surface, an upper opening having a width greater than the lower bottom surface, and an inclined surface formed between the upper opening and the lower bottom surface and mounting grooves, each formed in the reflective groove and having a lower bottom surface, an upper opening having a width greater than the lower bottom surface, and an inclined surface formed between the upper opening and the lower bottom surface; an insulating layer selectively formed on the heat-dissipating substrate; wiring pattern layers formed on the insulating layer and extending to bottom surfaces of the mounting grooves to be selectively formed thereon; a light emitting diode chip mounted in each of the mounting grooves; and a molding layer formed around the light emitting diode chip. | 02-14-2013 |
