An illumination apparatus comprises: a long LED unit provided, on one surface side in the thickness direction thereof, with light emitting devices using LED chips; a reflector plate held by the apparatus body; a lighting device for turning on the LED unit; and a heat dissipation block for dissipating the heat generated by the LED unit, the heat dissipation block being disposed on the other surface side of the LED unit and having the LED unit interchangeably attached thereto. An embedding section in which the LED unit is embedded is formed in the reflector plate, and the heat radiation block is held by the reflector plate. A flat surface portion from the portions of the LED unit, the portions being those from which the light from the light emitting devices is extracted, and a portion of the reflecting surface of the reflector plate, the portion being located in the periphery of the embedding section, are made to be flush with each other. |
