PURPOSE: To provide the lighting system with a heat exchanger, which warms water, and works for energy saving, by providing a plurality of pipelines and connecting pipes, in which heat exchanging medium is circulated, for the upper part of a luminaire frame to which floodlights are mounted. CONSTITUTION: The luminaire 1A is made up of floodlights 1, an equipment frame 8, pipelines 4, and of a reflection plate 2, connecting pipelines 5 are connected to the pipelines 4 so as to be formed into one pipe, and according to circumstances, they are connected to those of the another lighting system. Power supply voltage is applied to the floodlights 1 by electric cables 3, the floodlights emit illuminating light, and concurrently, are running heat, so that heat exchanging medium, that is, water circulated in the insides of the pipelines 4 which are laid via the reflection plate 2 and the frame 8, and excellent in thermal conductivity, is thereby warmed up. Water thus warmed up can effectively be utilized for building equipment, so that it can work for energy saving. |
