Abstract:
1. A light emitting device comprising: a light source; an optical component including a light incident surface, the light incident surface facing the light source; and a wavelength conversion member to convert a wavelength of at least a portion of light emitted from the light source from a first wavelength to a second wavelength which is different from the first wavelength, said wavelength conversion member being provided between the light source and the light incident surface, the wavelength conversion member crossing a first region and extending to a second region outside the first region, the first region being surrounded by the light incident surface and light paths of light that is emitted from the light source and enters edges of the light incident surface, the light source is a blue light source, and the wavelength conversion member is configured to convert the wavelength of at least the portion of the blue light emitted from the blue light source from the first wavelength which corresponds to the blue light to the second wavelength which corresponds to either red light or green light, so as to convert the blue light into either the red light or the green light.
