Abstract
An LED illumination apparatus includes at least one connector and a lighting drive circuit. The connector is connected to an insertable and removable card-type LED illumination source, which includes multiple LEDs that have been mounted on one surface of a substrate. The lighting drive circuit is electrically connected to the card-type LED illumination source by way of the connector. The card-type LED illumination source preferably includes a metal base substrate and the multiple LEDs that have been mounted on one surface of the metal base substrate. The back surface of the metal base substrate, including no LEDs thereon, thermally contacts with a portion of the illumination apparatus. A feeder terminal to be electrically connected to the connector is provided on the surface of the metal base substrate on which the LEDs are provided.
