Optical semiconductor lighting apparatus

摘要

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.

主权项

1. An optical semiconductor lighting apparatus, comprising:
a housing comprising a first end portion and a second end portion, wherein the first and second end portions comprise two separate pieces forming a plurality of outer vents therebetween; a light source module disposed inside the housing, the light source module comprising a plurality of optical semiconductor elements; a reflector forming at least a portion of the second end portion of the housing, wherein:
the reflector comprises a first surface configured to reflect light emitted from the light source module and a second surface formed opposite to the first surface;the second surface is exposed to ambient air; andthe reflector is coupled to a plurality of end portion supports disposed on the second end portion, each of the end portion supports being separated from one another by the plurality of outer vents, respectively; a fan disposed inside the housing adjacent to the light source module, wherein:
the fan is disposed above the plurality of outer vents with respect to air flow from the fan;the fan is configured to rotate in a first direction whereby air is blown through the plurality of outer vents towards the light source module and is ejected over the second surface of the reflector; an inner vent disposed in a base plate along an axis that is at an acute angle with respect to a vertical line, the inner vent being disposed between the light source module and the outer vent.
