An optical semiconductor illuminating apparatus capable of being simply installed and built, easily detecting a fault generation point, being simply repaired and replaced, and being compactly implemented. A bracket assembly having a power supply embedded therein is mounted at an upper side of a heat sink including a fixed unit, the power supply is seated on the heat sink including the fixed unit, a plurality of heat radiation fins protrude from an inner surface of the heat sink, and an upper surface of the power supply is disposed at a position higher than or equal to that of an edge of an upper end portion of the heat sink. |
