<P>PROBLEM TO BE SOLVED: To provide a new cooling means in a lighting device using an LED element, which enables downsizing, weight reduction, and cost reduction while aiming at a higher output. <P>SOLUTION: In the lighting device 1 using an LED element 2 having a cathode terminal 22 and an anode terminal 23 on a light-emitting body 21, the cathode terminal 22 and the anode terminal 23 are thermally and electrically connected with a terminal heat-dissipating body 15, and the terminal radiator 15 is connected with a feed line. The light-emitting body 21 is thermally connected with a body heat-dissipating body 14 which is electrically isolated against the terminal heat-dissipating body 15, and the lighting device 1 is supported by the body heat-dissipating body 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
