Automatic adjustment device for reducing dazzle |
摘要 |
An electronic incident light level evaluation circuit comprises a photosensitive element (1) coupled to one input of a comparator (2) controlling a power transistor (4) for energising and setting an electromagnet (5). The comparator (2) employs an integrated operational amplifier and a polarisation stage with a variable resistance for adjustment of the circuit threshold.
