Optical semiconductor based illuminating apparatus

摘要

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.

主权项

1. An optical semiconductor illuminating apparatus, comprising:
a heat sink comprising a light emitting module disposed on a lower side thereof, the light emitting module comprising at least one semiconductor optical element; a fixed unit disposed at one side of the heat sink and configured to be fixed to a ceiling structure; a power supply disposed on an upper side of the heat sink; and a bracket assembly having the power supply embedded therein and mounted at the upper side of the heat sink, wherein: the bracket assembly comprises:
a lower body mounted at the upper side of the heat sink and supporting the power supply; andan upper body, coupled to the lower body, enclosing the power supply over the power supply and coupled to the upper side of the heat sink; the heat sink comprises:
a heat radiation plate having the light emitting module disposed on a lower surface thereof;a hole penetrating through the heat radiation plate; andheat radiation fins protruding radially from an upper surface of the heat radiation plate; the lower body electrically connects the power supply and the light emitting module to each other through the hole; and the lower body comprises:
a lower case opened at an upper side thereof to allow the power supply to be seated thereon and having the upper body coupled to the upper side thereof; anda tube body extended from a lower surface of the lower case and configured to allow a cable for power connection to pass from the power supply to the light emitting module through the hole.
