<P>PROBLEM TO BE SOLVED: To provide a light-emitting device which has a large current supply amount and a long lifetime, and to provide a heat release method of the light-emitting device. <P>SOLUTION: On the inner periphery side of a cylindrical tube 1 which has translucency, a transparent anode layer 12b, an organic layer OL, and a cathode layer 12g are formed in order. Sealing members 110a and 110b are fitted to the cylindrical tube 1 so as to airtightly seal a region including an organic EL (Electro Luminescence) element 12. A heat pipe 21 is arranged extending from an inner periphery side of the cathode layer 12g to the sealing members 110a and 110b in an airtightly sealed space, and configured to conduct heat occurring in the organic EL element 12 to the sealing members 110a and 110b. <P>COPYRIGHT: (C)2011,JPO&INPIT |
