<P>PROBLEM TO BE SOLVED: To provide a luminescent module which can raise a light retrieving efficiency from a mold coating a light emitting element chip, and which can hence obtain a higher luminance. <P>SOLUTION: The luminescent module 1 includes the light emitting element chip 20 having a luminescent layer 24 made of a laminate of compound semiconductor layers, and the mold 60 having light transmission properties to an emitting light luminous flux from the luminescent layer 24. The mold 60 has a first mold layer 10 in which a refractive index of the light emitting element chip 20 in an ambient space is 1.45 or more, and is smaller than the refractive index of a compound semiconductor for forming the uppermost layer of the light emitting element chip 20, and a second mold layer 11 made of a fluororesin in which a refractive index is 1.0 to less than 1.45 at the outside of the first mold layer 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
