PROBLEM TO BE SOLVED: To provide a light generating module which realizes both of positioning of a lens for directing light from a semiconductor light emitting device and satisfactory radiation from the semiconductor light emitting device. SOLUTION: A light module 80 comprises a housing 82, the semiconductor light emitting device 84, a first mounting face 86, a second mounting face 88, and a lens 90. The housing 82 comprises a base 83 and an optical window 92. The base 83 is made from material exhibiting a first thermal conductivity. The first mounting face 86 mounts the lens 90. The second mounting face 88 mounts the semiconductor light emitting device 84. The lens 90 has an installation face 90a mounted on the first mounting face 86, and is used to direct light from the semiconductor light emitting device 84 toward the optical window 92. In the light module 80, the first mounting face 86 is made from material exhibiting thermal conductivity which is not lower than the first thermal conductivity of the base 83. The second mounting face 88 is made from material exhibiting thermal conductivity which is not lower than the first thermal conductivity. COPYRIGHT: (C)2006,JPO&NCIPI
