Claim Text:
1. An illumination unit comprising: one or more light sources each including a solid-state light-emitting device including a package and at least one chip mounted on the package, each chip configured to emit a light beam as a light-emitting spot; and an optical member having a minor axis and a major axis, and allowing incident light from the solid-state light-emitting device to pass therethrough, wherein a total of at least three of the light-emitting spots are provided within the whole of the one or more light sources, to allow the whole of one or more light sources to emit light beams in two or more wavelength bands different from one another, wherein the solid-state light emitting device in a first one of the light sources includes a plurality of the chips mounted on the same package, each of the chips emitting light in the same wavelength band, wherein at least one chip of at least one of the light sources includes a laser diode, wherein a second one of the light sources includes a plurality of light-emitting spots and includes a chip including the laser diode, and wherein the second light source is configured to emit light beams of two or more different wavelengths, and wherein directions of major axes of the far field patterns of the light beams of two or more different wavelengths are substantially aligned with each other.
