AN ELECTRICAL CIRCUIT AND A METHOD FOR MEASURING THE POWER CONSUMPTION OF AN LED LIGHTING DEVICE

摘要

Embodiments consistent with the present disclosure provide an electrical circuit and a method for measuring the power and power consumption of an LED lighting device in real time. The circuit includes a controlling unit configured to process data; a display unit configured to display data received from the controlling unit and other components; a power supply and driving unit configured to supply power; an LED light source; and a RF unit configured to send data to remote terminals. The electrical circuit further includes an input power sampling unit, an output voltage sampling unit, and an output current sampling unit, which are configured to capture the real time input voltage, output voltage, and output current data respectively. Further, the controlling unit may determine the power and power consumption of the LED lighting device by using the received real time voltage and current data measurements, and referring to the stored input voltage-efficiency curves.
