Patent ID: 8207548

Claim:
A semiconductor light emitting device comprising: a base substrate; a multilayer epitaxial structure that (i) includes a first conductive layer, a second conductive layer and a light emitting layer that is formed between the first conductive layer and the second conductive layer, (ii) has a shape of a cylinder with a substantially circular or N-sided polygonal cross-section, where N is an integer equal to or larger than five, (iii) is formed on the base substrate in such a manner that the first conductive layer is positioned closer to the base substrate than the second conductive layer is, and (iv) is divided into a plurality of portions which are a plurality of independent light emitting elements, the plurality of portions being formed by (a) equiangularly spaced division grooves radially extending from a center of the cylinder and dividing the cylinder into sector forms and (b) division grooves dividing the sector forms in a circumferential direction of the cylinder, the light emitting layer included in each independent light emitting element having a substantially same area; and a phosphor film that covers a main surface of the multiplayer epitaxial structure which faces away from the base substrate, and every side surface of the multilayer epitaxial structure from a layer including the main surface to include at least the light emitting layer.
