OPTICAL SEMICONDUCTOR LIGHTING APPARATUS

摘要

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.
