A Case Study on Different Lighting Systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Techno-economic performance comparison of Compact Fluorescent Lamps (CFL) with Light Emitting Diodes (LED), fluorescent tubes, incandescent bulbs was carried out in view of worsening power and energy crisis. However, tubes, LED, CFL and External Electrode fluorescent lamps (EEFL) lamps worsen electric power quality of low voltage networks due to high current harmonic distortions (THD) and poor power factors (PF). Expenses of low THD and high PF CFL, incandescent lamps and LED lamps may be four to eight times higher that poor THD and deteriorating PF lamps. Selection of a lighting source hinge on THD, operating PF, shelf life, energy expenditure, power consumption, efficacy, colour rendering index (CRI) and associated physical effects. This paper recommends designing consumer based novelties to avoid low operating power factor. LEDs are the future for lighting in industrial, commercial and residential purposes. Government and commercial buildings may consider full spectrum hybrid thermal photovoltaic and solar fiber optic illumination systems.
