Acoustic resonances are observed in high-pressure discharge lamps operated with ac input modulated power frequencies in the kilohertz range. This paper describes an optical resonance detection method for high-intensity ...

This paper is based on the application of stochastic differential equations in simulating the active power consumption in street lamp operation, both in transient and steady state. The method worked as follows. Firstly, a ...

In a homemade UV-Ozone generator, different ignition tubes extracted from HID mercury vapor lamps were investigated, namely: 80, 125, 250 and 400 watts. The performance of the generator in function of the type of the ...

This work presents and analyzes a new family of electronic ballasts to supply metal halide lamps applied to interior lighting systems. These lamps present the best light quality among the high intensity discharge lamps, ...

The Dielectric Barrier Discharge (DBD) Excimer Ultra-Violet (UV) lamps are a promising technology offering several advantages over other sources of UV light. In particular, the application of this type of lamps for drinking ...

The widespread use of discharge lamps and solid-state lighting is justified by its high-energy efficiency. However, the massive use causes degradation of power quality provided. In this context, the objective was the ...
