Transcript
We opened the back end of the fixture to expose the AC wiring. Power to circuit board Ground Positive Neutral Positive Ground Neutral On/Off switch For our experimentation purposes we broke out the wiring in order to measure voltage and current. 120V, 60Hz, 4.2A UL listing Positive to lights Neutral to lights Power to circuit board Added wiring from power supply on back of circuit board to manual toggle switch This is the sensor circuit board. Infrared light impinges the sensor through a diffuser lens. Changes are interpreted as motion. Timer circuitry Photo resistor Infrared motion sensor Controller Capacitors Wiring added to power supply for on/off toggle Relay With our breakout box we can measure differences between incandescent, CFL and LED bulb performance. 116.5 volts 232 mA current 14W - .23A (listed on bulb)
