Abstract: The illuminants arrangement includes a plurality of LED-based light sources that are encased in a water-tight manner by way of one or more encasings, wherein the light sources are, at least in a group-wise manner, operationally interconnected by way of electrical connection leads. The connection leads include voltage supply leads. The illuminants arrangement as a protection of the one or more encasings and the light sources from mechanical damage includes at least one protective overlay for being placed onto the one or more encasings, so that light emitted by the light sources can be emitted through the at least one protective overlay. The illuminants arrangement can include a heating device. Each of the light sources can be suitable for emitting light of a variable color, wherein the color of each of the light sources can be individually selected by way of a control unit.
