<P>PROBLEM TO BE SOLVED: To carry out efficient heat transport (heat radiation) of a light source such as an LED, with the use of a heat pipe of high rigidity and with a cross-section shape hardly deformable. <P>SOLUTION: The heat pipe 4 has an outer shape of a cross section vertical to its length direction to be an open shape partly equipped with a symmetrical concave shape 4i, and the light source 2 is arranged with an interposition of a light-source setting block 3 at a position toward a side of the outer shape of the symmetrical concave shape 4i of the heat pipe 4, with a given distance x from the concave shape 4i on the center line O of the symmetrical concave shape 4i. <P>COPYRIGHT: (C)2010,JPO&INPIT |
