Document Type and Number:
Japanese Patent JP5367898
Kind Code:
B2
Abstract:
An optical semiconductor lighting apparatus with enhanced heat dissipating efficiency and dust-proof efficiency is disclosed. The optical semiconductor lighting apparatus comprises a housing which is open at a side thereof, a light source module disposed in the housing and having at least of a light source, a fan disposed adjacent to the light source module and blowing air to the light source module, and a reflector reflecting the light generated from the light source module to determine an illumination scope of the light. In the housing, a moving path discharging, through the light source module, at least a portion of the air drawn by the fan is formed. Since at least a portion of the air blown to the light source module by the fan is discharged through the moving path inside the housing, thus, external dusts can be prevented from moving toward the light source module.
