Abstract:
1. A light emitting semiconductor, comprising: a base substrate; a light emitting semiconductor element including a crystal growth basis and provided on the base substrate so that the crystal growth basis faces in an opposite direction to the base substrate; a first transparent sealing medium which seals the light emitting semiconductor element on the base substrate and includes a first ceiling portion which is positioned over the light emitting semiconductor element, a first taper portion which includes a first slantingly inclined side wall and is provided so as to continue from the first ceiling portion, and a first R portion which includes a first curve and connects between the first ceiling portion and the first taper portion by the first curve; and a second sealing medium which comprises a phosphor and seals the light emitting semiconductor element over the first sealing medium and includes a second ceiling portion which is positioned over the first ceiling portion and includes a recess which dents toward the first ceiling, a second taper portion which includes a second slantingly inclined side wall and is provided so as to continue from the second ceiling portion, and a second R portion which includes a second curve and connects between the second ceiling portion and the second taper portion by the second curve, wherein an inclination angle of the second slantingly inclined side wall is more than an inclination angle of the first slantingly inclined side wall.
