<P>PROBLEM TO BE SOLVED: To provide a high quality light emitting device, its mounting method, a lighting apparatus and a display for simply realizing highly efficient heat radiation with a small space, for stabilizing the output or light emission wavelength of a light emitting element, for improving the reliability of the light emitting element, and for lengthening the life of the light emitting element. <P>SOLUTION: In a light emitting device where the die bonding and wire bonding of a plurality of light emitting elements 20 is carried out on a substrate 10; a plurality of recesses 11 are formed on a substrate upper face 10b, the die bonding and wire bonding of each light emitting element 20 is carried out in each recess 11, and a groove 12 for heat radiation is formed on a substrate back face 10b. A heat pipe 30 is formed so as to be butted in each groove 12. The cross-section of the heat pipe 30 is formed so as to be shaped like an ellipse. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
