THE COMPARISON OF PRACTICAL AND ECONOMICAL ASPECTS OF UTILIZATION OF VARIOUS LIGHT SOURCES
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2012, Vol 59, Issue 259
Abstract
The diversity of the properties of available light sources, such as: the energy consumption, expected lifetime and the price, can be a problem in terms of selection process of the most suitable product. In order to obtain reliable information allowing to make the right choice, the long term tests are the best way, as one can verify the reliability and observe the properties change in terms of the time of duty and number of power on/off cycles. In this work we present the results of the observation of the lifetime and its impact on the economical analysis of such light bulbs: LED – based, halogen, compact fluorescent lamp and traditional ones. The results of the investigation of the degradation process related to the time of work and power on/off cycles will be presented. Acquired data allowed to observe specific effects related to various light sources. Additionally, the comparison was referred to various price-groups and related reliability expectations.
