Optical semiconductor lighting apparatus

Abstract

A optical semiconductor lighting apparatus includes: a board; a drive IC which is disposed in a central portion of the board; a plurality of semiconductor optical devices which is disposed adjacent to and around the drive IC in the board in a grid shape in one or more rows and columns; a non-insulating heat sink in which the board is disposed; an insulating housing which accommodates the heat sink and protects the drive IC and the plurality of semiconductor optical devices from withstand voltages; and a first optical member which faces the plurality of semiconductor optical devices, transmits or reflects light irradiated from the semiconductor optical devices, and forms a vertical vent hole corresponding to the drive IC; and a second optical member which is connected to an upper side of the housing and forms light distribution by refracting light transmitted or reflected from the first optical member.
