Abstract: In an electronic flash apparatus having a flash tube (2) which is disposed inside a reflector (3), having a storage capacitor (5) which can be discharged via the flash tube having a d.c. voltage converter (7) which is fed by a d.c. voltage source, preferably a battery (6), and by means of which the storage capacitor (5) can be recharged to its operating voltage following each discharge, and having a control circuit (8) which switches the d.c. voltage converter (7) on or off as a function of the voltage at the storage capacitor (5), overheating of the reflector (3) and/or its front elements (4) is prevented by a protective circuit (12) which influences the flash light emission in such a way that the temperature of the reflector (3) and/or its front elements (4) does not exceed a predetermined maximum value.
