PROBLEM TO BE SOLVED: To provide an LED lighting device which lowers heat transfer resistance of a substrate support supporting an LED substrate and thereby achieves high heat radiation performance. ! SOLUTION: An LED lighting device includes: an LED substrate serving as a light source; and a substrate support, which supports the LED substrate, in a body. The substrate support is formed into a block shape and is disposed in the body so as to match with a radiation direction of the LED substrate. ! COPYRIGHT: (C)2014,JPO&INPIT |
