Reliable Energy Strategy Based on Incandescent Lighting

摘要

The artificial lighting used today in home and workplace have confirmed capability to induce skin problems, DNA damage, tumor formation as well as worsening arthritis, migraine and visual fatigue by longer exposure of ultraviolet radiation from discharge lighting sources. In this paper an ignition-angle controller (IAC) is used to demonstrate the reliability of incandescent lamps (ILs) in comparison with discharge lighting feed by switching-mode supplies. Analysis of harmonic of the line-current flow consumed by the ignition-angle controller (IAC) circuit has shown that production of distorted rms currents does not produce hazard, because single harmonic distortion (SHD) values are keeping lower to 50%. As energy policy, the modern artificial lighting must be replaced by economical, stable and nonhazardous incandescent lamps (ILs).
