Primary light converter for converting primary light into secondary light

摘要

The invention relates to a primary light converter (1) for converting primary light (3) into secondary light (4). An electrical light conversion unit (2) converts at least a part of the primary light (3) into the secondary light (4), and an energy converter (5) converts at least a part of the primary light (3) into electrical energy, wherein the electrical light conversion unit (2) is adapted to be driven by the electrical energy from the energy converter (5). The invention relates further to a lighting apparatus comprising one or several of the primary light converters. It is not necessary to electrically connect the one or several primary light converters via a wire to an external power supply. This reduces the space required for the primary light converter and the lighting apparatus and increases the variability of possible arrangements of the one or several primary light converters and lighting systems comprising such primary light converters.
