Product Description Po170 is a photoelectric integrated sensor with a typical incident wavelength of λp=520nm, built-in dual-sensitive receiver, visible light rangeHighly sensitive, the output current varies linearly with illumination. Suitable for TVs, LCD backlights, digital products, instrumentation, industrial equipment, etc.Multi-domain energy-saving control, automatic sensitization, and adaptive control.Electrical characteristicsLow dark current, low illumination response, high sensitivity, and linear change with increasing illuminance;Built-in dual sensitive element, automatically attenuates near infrared, and the spectral response is close to the human eye function curve;Built-in micro-signal CMOS amplifier, high-precision voltage source and correction circuit, large output current, wide operating voltage range, stable temperatureGood sex;Optional optical nano material package, visible light transmission, UV cut-off, near-infrared relative attenuation, enhanced optical filtering effect;Conforms to EU RoHS Directive, lead-free and cadmium free;Above for optical streetlights during the day, street lamp extinguishes circuit automatically litlamps at night. Figure, capacitance C1, C2, R3 and diode D1 and regulator tube DW,composition simple capacitance step-down, switch on the power rectifier circuit for the DCvoltage 12V or so. Transistor BG, environmental light detectors and bidirectionalthyristor, photoelectric switch circuit composed.During the day, environmental light detectors by light show low resistance, BGpipe base potential fell, the BG deadlines, no voltage output resistance R1, so bidirectionalthyristor SCR at shutoff state, bulb technologies not bright.When night falls, environmental light detectors because there is no light its darkresistance increases, make BG base potential rise and conductivity, the output voltage triggeron R1 conduction, streetlights SCR silicon to electric light. Adjust potentiometer W, adjustableheight, namely BG base potential adjust the sensitivity of the mastery of light.
