LED news and insight from our technology editor Steve Bush, who has been messing with LED lighting for more years than he would care to remember.
Power measurements on LED lights
Just a quick post to flag a Test & Measurement article that touches on LEDs – Testing for energy efficiency
Guest columnist Clive Davis of Yokogawa Europe describes how measuring technologies play their part in the drive to design more energy efficient systems and products, both from the point of view of ensuring optimum energy efficiency and meeting the compliance targets of international standards and the related legislation.
Power measurements on fluorescent and LED lights are another key application. Since the switching frequency of fluorescent lights can be tens of kilohertz, a wide range power measurement is required. In addition, dimming control using PWM modulation circuit is used with LED lights.
The new analyser provides a wide range from DC to up to 5MHz to allow the resultant harmonic signals to be evaluated.
