Claim Text:
1. A light emitting apparatus comprising: a light source member having a plurality of light source parts each with one or more light sources that output light of an arbitrary wavelength ranging from 20 nm to 1 mm under external power supply; and a light guide member having input surfaces through which the light from the light source member is input and other end surfaces through which the input light is output, wherein: the adjacent light source parts of the light source member output light of different wavelengths; the light guide member includes a recess formed at an upper position with respect to the light source member and between the respective input surfaces through which the light from the corresponding light source parts is input, the recess having a recess upper horizontal surface and a recess side surface substantially vertical with respect to the recess upper horizontal surface that reflects at least some of the light input through the input surfaces, a plurality of extension parts that respectively guide mainly the light input through the input surfaces from the corresponding light source parts, and a cutout portion formed between the extension parts, and the recess is formed at the opposite side of the light guide member from the cutout portion with a portion of the light guide member between the recess and the cutout portion, and the recess and the cutout portion are disposed such that the light from the light source parts does not pass directly through the portion of the light guide member between the recess and the cutout portion.
