Embodiments of the invention provide an optical semiconductor illuminating apparatus, which includes a heat dissipating base; a light emitting module comprising at least one semiconductor light emitting device and mounted on a lower side of the heat dissipating base; and a plurality of heat dissipating fins each having opposite edges protruding from opposite sides of the heat dissipating base and being mounted on an upper surface of the heat dissipating base.

Optical semiconductor illuminating apparatus

A first heat sinking path formed in a forming direction of a heat sink unit disposed radially in a housing where a light emitting module is mounted. A second heat sinking path is formed along an edge of the light emitting module. By providing a light engine concept in which a light emitting module, an optical member, and a heat sink unit are included and a bottom surface is gradually widened from one side to the other side, an optical semiconductor lighting apparatus can reduce a total weight of a product, can further improve heat dissipation efficiency by inducing natural convection, is simple in the product assembly and installation, and is easy in maintenance, and can provide products with high reliability by increasing the arrangement efficiency of semiconductor optical devices per unit area.
