<P>PROBLEM TO BE SOLVED: To provide an illumination apparatus, in which an illumination direction of light of a lighting body can be changed, and heat can be conducted from a high temperature part of the lighting body to a heat dissipating member. <P>SOLUTION: The illumination apparatus 1 includes: the lighting body 2 having a cylindrical outer frame 22 accommodating an LED package 21; an attachment member 5 provided with a tubular rotation drum 51 extended vertical with respect to a ceiling surface 6; the heat dissipating member 3 having fins formed by good heat conductors, and rotatably attached to the rotation drum 51; and an arm 7 attached to the heat dissipating member 3. A cooling part 42 at one end of a heat transmitting body 4 composed of a heat pipe is inserted to the heat dissipating member 3, and the heat transmitting body 4 integrally rotates with the heat dissipating member 3. A heat receiving part 41 at the other end of the heat transmitting body 4 is extended in the horizontal direction of the ceiling surface 6, and the heat receiving part 41 is attached with the lighting body 2 capable of rotating by a bearing part provided in the outer frame 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
