The lighting fixture includes at least one ballast configured to receive a dimming test signal. The diagnostic device includes a controller module configured to trigger a test sequence when the ballast receives the dimming test signal. An output current of the ballast is adjusted in accordance with...

Case study: Lighting Ballast Evaluation In most facilities, lighting is a major element of operating cost. Part of that cost is due to energy, and part is due to maintenance. Power quality Article Case study: The Malfunctioning Medical Machine This case history is a classic example of the imp...
LEDs are powered by a DC line generated by a switching power source. For theDC power analysis, a data acquisition system with high bandwidthand a high sampling rateare necessary due to the high switching frequencies of the ballast units or switching regulators in fluorescent lighting and LEDs. ...
A focus of this paper is on lamp-electronic ballast compatibility testing with ceramic discharge metal halide lamps that are used in applications ranging from specialty store lighting to gas station canopy lighting. Testing guidelines are discussed in this paper for low frequency (LF) electronic ...
