<P>PROBLEM TO BE SOLVED: To provide an LED package capable of highly efficient heat radiation and ensuring stable color conversion and transmitted light quantity. <P>SOLUTION: A refrigerant R is sealed in the inside of a case member 30 covering an LED chip 20. A phosphor P is diffused in the refrigerant R. According to this configuration, heat exchange occurs between the heat-generating LED chip 20 and the refrigerant R therearound, and heat convection occurs in the refrigerant R. The heat is transmitted by the heat convection to the case member 30, and is radiated in the ambient air via the case member 30. In this way, highly efficient heat radiation can be possible. Further, since the heat convection causes uniformity of diffusion in the refrigerant R of the phosphor P, the stable color conversion and transmitted light quantity can be ensured. Still further, since no special countermeasure is required for uniform diffusion of the phosphor P in manufacturing steps, the manufacturing steps can be simplified. <P>COPYRIGHT: (C)2008,JPO&INPIT |
