Comprehensive view of LED products in luminaires

Nowadays, the LED technology is still more and more forthcoming technology. LED luminaires slowly replace traditional luminaires because their energy consuming in comparison with light output expressed by means of luminous efficacy lm/W increase to higher values what certainly save electrical energy consumption. At the present the popular way traditional light sources are replaced by LED retrofit lamps which has socket as traditional fluorescent lamps or light bulbs which can be easily mounted into traditional luminaires. The users are requested by LEDs, and they often do not realize the impact of exchange in a conventional lamp. The paper deals with electrical and photometric characteristics of LED retrofits, which are intended as a replacement for linear fluorescent sources. The above is a detailed analysis of the electrical wiring and also is shown the difference in SPD of individual light sources.
