Title: Daylight actuated light switch control circuit - has triac and delay device between two comparators, with one comparator connected to switch at other comparator
IPC: H05B39/08
Filed: 1980-03-05
Abstract: The lighting control circuit for e.g. an office is designed to operate under different lighting conditions but includes a delay so that the lights are not switched off and on too frequently on e.g. a cloudy day. A comparator (K1) is preceded by a junction (1) to which actual value and nominal value voltages are applied. This gives a positive output when the actual value is greater than the nominal value. This is followed by two resistances (R3, R4) and a capacitor (C1) forming a delay device. The delay device is connected to a second comparator (K2) followed by a trial stage (TR). The output of the second comparator is also connected by a second line (2) to a switch (S1) which operates hysteresis dependent on the of the two coupling resistances (R1, R2) at the input of the first comparator. A diode (D1) is in parallel with the second resistance (R4) of the delay device so that negative signals pass through without delay.
