<P>PROBLEM TO BE SOLVED: To solve a problem with respect to an illuminating apparatus using a plurality of light-emitting-diode light sources that it is apt to be high in manufacturing cost since one or a set of a few lenses out of a plurality kinds of lenses need to be used for each light source module because a light distribution desired of each light source module is different from that of the other. <P>SOLUTION: A plurality of light source modules are used, in each of which resin including a scattering material is arranged between a semiconductor light-emitting device and a lens. And, in applying a point that a light distribution changes in accordance with a concentration of the scattering material contained, resins having different scattering-material concentrations are used depending on angles of arrangement of the light source modules. Only by adjusting concentrations of the scattering material contained, the light source module having various light distributions can be actualized with only one kind of the lens. As a result, there is an effect of reducing the manufacturing cost of the illuminating apparatus. <P>COPYRIGHT: (C)2011,JPO&INPIT |
