Abstract
A light emitting device including a light source and a light transforming 101 member containing a fluorescent substance for absorbing at least a part of a light emitted from the light source and for emitting a light having a different wavelength. The light source includes a plurality of semiconductor light emitting units 104, at least a part of which are covered with the light transforming member 101. A shielding member 102 between a first semiconductor light emitting unit 104a covered with the light transforming member 101 and a second semiconductor light emitting unit 104b which is adjacent to the semiconductor light emitting unit 104a.
