Abstract
Abstract An electronic flash unit assembly having an electronic flash module separate from a power and control module. An assembly of articulated flash arms supports the flash module spaced from a camera. A power cord interconnects the power and control module with the flash module so that power is transmitted to the electronic flash tube from the power and control module when the power and control module is triggered. Preferably, a power cord connects the power and control module to the camera so that triggering of the module occurs upon movement of a shutter release member of the camera. The power and control module is connected to the tripod socket of the camera and supports the flash arm assembly. Alternatively, a mounting plate is connected to the tripod socket of the camera and supports the flash arm assembly, with the power and control module being in a separate unit.
