DEVICE FOR THE ECPOAURE OF PHOTOGRAPHIC RECORDING MATERIAL
A device ( 1 ) for the exposure of photographic recording material ( 6 ) comprises an exposure system ( 2 ) incorporating a multitude of light emitting diodes ( 12 a - 12 n, . . . , 20 a - 20 n; 40 a - 40 n, . . . , 50 a - 50 n ). These light emitting diodes ( 12 a - 12 n, . . . , 20 a - 20 n; 40 a...

) 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. |
