Abstract: The present invention provides a photographic lighting apparatus for illuminating a photographic object in taking the object with a camera such as a television camera or an 8 mm movie camera. The photographic lighting apparatus is capable of illuminating the object practically at a fixed intensity of illumination regardless of the variation of the distance between the object and the lamp thereof by reducing the brightness of the lamp when the object is located near to the lamp and increasing the same when the object is located remotely. The brightness of the lamp is regulated by controlling the conduction angle of a thyristor connected to the lamp according to the output signal of a photometric circuit which measures the intensity of illumination of the object.

Abstract: A computer type electronic photoflash consisting of a main photoflash unit having photoflash emission and photoflash light volume control functions and a plurality of adapters connectable thereto. Each of said adapters is used with a photographic camera for which an electronic photoflash of special make and design is to be used exclusively. Each adapter serves for relaying electrical signals between the camera and the main photoflash unit and has an electric circuit adapted for this purpose. Thus, the number of the adapters is selected to be equal to the number of different descriptions of the photographic cameras for which respective electronic photoflashes of special make and design are to be used exclusively.
