<P>PROBLEM TO BE SOLVED: To restrain temperature rise of a light source through sufficient cooling of the light source with air flow using a blower or the like, and also to restrain temperature rise of a power source substrate incorporated inside a case of the lighting device. <P>SOLUTION: A vortex flow fan 17 forms first air flow 40 evacuating air which is flowed into a first space S1 with an LED support body 2 arranged from outside of the lighting device 100, from the first space S1 to outside of the lighting device 100. A casing 16 separates between the first space S1 and a second space S2, and also prevents air flowing into the first space S1 from outside from flowing into the second space S2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
