Abstract
A device (1) for the exposure of photographic recording material (6) comprises an exposure system (2) incorporating a multitude of light emitting diodes (12a-12n, . . . , 20a-20n; 40a-40n, . . . , 50a-50n). These light emitting diodes (12a-12n, . . . , 20a-20n; 40a-40n, . . . , 50a-50n) are connected in a combination of at least one series circuit and at least one parallel circuit. This enables a large number of light emitting diodes to be provided in the exposure system (2), permitting a high light intensity and, accordingly, short exposure times. The voltages and currents required to operate the device (1) are therefore modest and do not necessitate a high technical expenditure for their generation.
