Abstract: Light emitted from a plurality of LED light sources can be introduced into a light guide and inwardly reflected (totally reflected) at a first reflective surface formed on the light guide to form a substantially collimated light. The substantially collimated light can then be inwardly reflected (totally reflected) at a second reflective surface and a third reflective surface. The light can then be led out of the light guide and emitted in a direction of illumination of the lamp. An increased amount of light provides a bright lamp. An arrangement of LEDs emitting different colored lights enables the different colored lights to be emitted at the same time or with time delays.

Abstract: In a method for maintaining a combined-cycle power station at readiness, an supplemental firing (44) with a fresh air supply fan (46) and, preferably, the feed and supply pumps (21, 23, 31, 38) are operated continuously or intermittently when the combined-cycle power station is not in use, in order to maintain specific states and media flows in the two-phase circuit of the combined-cycle power station. In one embodiment of the invention, the media in the two-phase circuit are prevented from freezing by means of the supplemental firing. Furthermore, media states which prevent air from entering while the power station is not in use and which thus prevent corrosion damage can also be maintained. In addition to this protective maintenance of readiness, the supplemental firing is also used when the combined-cycle power station is not in use, in order to produce and maintain conditions which allow the combined-cycle power station to be started and loaded quickly.
