  • Patent number: 8410509
    Abstract: A light emitting diode module for a line light source includes a circuit board having a wire pattern formed thereon and a plurality of LED chips directly mounted and disposed in a longitudinal direction on the circuit board and electrically connected to the wire pattern. The module also includes a reflecting wall installed on the circuit board to surround the plurality of LED chips, reflecting light from the LED chips. The module further includes a heat sink plate underlying the circuit board to radiate heat generated from the LED chip.

  • Publication number: 20090166664
    Abstract: There is provided a high power LED package and a method of manufacturing the same. The method includes: forming at least one chip mounting part and at least one through hole in a metal plate; forming an insulating layer of a predetermined thickness on an entire outer surface of the metal plate; forming an electrode part to be electrically connected to a light emitting chip mounted on the chip mounting part; and cutting the metal plate along a trimming line to separate the package. The LED package is free from thermal impact resulting from different thermal coefficients among components, thus ensuring stable heat radiation characteristics in a high temperature atmosphere. Also, the LED package is minimized in optical loss to improve optical characteristics. In addition, the LED package is simplified in a manufacturing and assembly process and thus can be manufactured in mass production at a lower cost.

  • Publication number: 20080048193
    Abstract: A white LED module includes a circuit board, a blue LED chip disposed on the circuit board, a green light source of an LED chip or phosphor disposed on the circuit board, and a red light source of an LED chip or phosphor disposed on the circuit board. At least one of the green and red light sources is a phosphor, which is excited by the blue LED chip to radiate. The blue LED chip emits light in a triangular region defined by color coordinates (0.0123, 0.5346), (0.0676, 0.4633) and (0.17319, 0.0048), the green light source emits light in a triangular region defined by color coordinates (0.025, 0.5203), (0.4479, 0.541) and (0.0722, 0.7894), and the red light source emits light in a triangular region defined by color coordinates (0.556, 0.4408), (0.6253, 0.3741) and (0.7346, 0.2654).
