Abstract: An optical semiconductor illuminating apparatus includes a light emitting module including semiconductor optical elements, a casing part disposed over the light emitting module and having a switching mode power supply (SMPS) embedded therein, a first airtightness part including a packing frame fixed to an outer side of an edge of a communication slot penetrating through a side surface of the casing part, and a second airtightness part provided to an upper side of the casing part.

Abstract: An optical semiconductor lighting apparatus including a housing with a first end portion and a second end portion that is open, a light source module disposed in the housing, a fan disposed adjacent to the light source module in the housing, the fan rotating in a first direction to blow air toward the light source module, and a reflector disposed adjacent to the second end portion of the housing, the reflector enhancing an illumination scope. A moving path, in which at least a portion of the air drawn into the housing by the fan externally flows through the light source module, is formed in the housing.

Abstract: An optical semiconductor based illuminating apparatus including a housing having an opening portion, a lighting unit disposed adjacent to the housing that includes at least one optical semiconductor, a power supply mounted within the housing that supplies power to the lighting unit, and a gate unit connected to the opening part that opens and shuts the inner housing.

Abstract: An optical semiconductor lighting apparatus having at least one or more clamping units are formed along a longitudinal direction of a race way. A first sealing unit finishes both ends of a housing attached to or detached from the clamping unit. A second sealing unit surrounds upper and lower portions of both edges of an optical member disposed on the bottom surface of the housing. A wireless communication unit receives a dimming signal through a wireless communication network, and outputs the received dimming signal to a power supply unit. The power supply unit supplies a DC voltage to the light emitting module to control the illuminance of the light emitting module according to the dimming signal input from the wireless communication unit.
