| 摘要 |
The present invention relates to an optical semiconductor illuminating apparatus which includes a housing which receives a heat sink; a substrate arranged in the heat sink; semiconductor optical devices which have a driving IC arranged in the center of the substrate and are adjacent around the driving IC; a first optical member which faces the semiconductor optical devices and transmits and reflects light emitted from the semiconductor optical devices, and has a vent hole which is vertically penetrated by corresponding to the driving IC; and a second optical member which is combined with the upper side of the housing and refracts light which transmits or is reflected from the first optical member and distributes it. The present invention relates to an optical semiconductor illuminating apparatus which uses semiconductor optical devices as a light source by using limited space and area to correspond to a single lens and also performs uniform and smooth heat dissipation. |
