Abstract
Various light sources are applied for signaling (traffic lights, information boards and advertising boards). Mainly, there are halogen reflectors, light emitting diodes (LED) and standard sources of laser light. Light intensity measurements were performed as emitted from 1mm2 of source area. It enables easier evaluation and comparison in terms of best matching of particular light sources to fiber optic technology.
