PURPOSE: A LED lighting device compulsorily sends inflow air from an air inlet to a power supply unit, and thus increases efficiency of heat dissipation. CONSTITUTION: An optical source section (110) comprises a light emitting surface. The light emitting surface is mounted with LED emitting light to the front A heat sink portion (120) emits heat of the optical source section. A blower (150) ejects air flowed in from an air inlet through an air diffuser. A housing forms an installation space of the blower and the heat sink portion. |
