Abstract
The problematics concerning the illuminating applications of optical fibers and transparent insulations have been examined in this research. The experimental installations of the research have given information about the practical adaptability of fiber optic lighting and transparent insulation in different usages. In illuminating engineering optical fibers are given demands which partly differ from communications technology. According to this research the importance of the coupling efficiency must especially be emphasized. Step index multimode fibers with large numerical apartures are most applicable for transferring the visible spectrum of light. Perhaps the most important feature of fiber optic lighting is the absence of electrical current and heat in the light transmitted through a light guide e.g. a fiber bundle. The light can be supplied by fiber bundles into the hazardous operating conditions while the light sources are being positioned in a separate room. The waste heat generated by centralized light sources can be either disposed or used in the heating system. The centralized positioning of light sources also facilitates the maintenance. Both energy losses and overheating problems of conventional windows can be reduced by using transparent insulation in light apertures. The insulation is also able to prevent rooms from disturbing direct sunlight and

However, windows in the working rooms can not be replaced by the transparent insulation materials, because the important visual contact outside will be lost.}
