  • Patent number: 10477670
    Abstract: A flexible circuit board assembly for an LED lamp of the present disclosure comprises: a resin layer having a strip shape; a conductive signal line layer formed from a predetermined pattern provided on the upper part of the resin layer; and a radiation layer provided on the lower part of the resin layer, having a thickness relatively thicker than that of the conductive signal line layer, and radiating the heat generated from an LED mounted on the signal line layer, wherein the signal line layer and the radiation layer are made from one material from among copper, aluminum, copper alloy and an aluminum alloy.
    Type: Grant

  • Patent number: 8648379
    Abstract: Provided is a light emitting diode (LED) lamp assembly having an increased light incidence angle by fixing unit LED lamps fixed on a substrate at various angles. The LED lamp assembly includes a substrate having a socket portion and an LED mounting portion, first unit LED modules installed on both surfaces of the substrate and irradiating light onto the both surfaces of the substrate in a frontward direction, and second unit LED modules irradiating light onto the both surface of the substrate in directions other than the frontward direction. In the LED lamp assembly, since first and second unit LED modules having light irradiation units formed at different positions are installed on both surfaces of a single substrate, light can be irradiated in a radial direction.
