Abstract: A lamp, which has a light source having several light-emitting elements, in particular in the form of LEDs. The lamp has first passage openings on a first side next to the light source and second passage openings on a second side next to the light source. The passage openings are designed for an air flow for cooling the light source. The lamp also has a first air-conducting surface on the first side next to the first passage openings and below the light source and a second air-conducting surface on the second side next to the second passage openings and below the light source, wherein the two air-conducting surfaces are designed in such a way that the two air-conducting surfaces form an air incidence region that expands away from the light source.

Abstract: A support rail for holding and supplying power to a plurality of lighting modules. The support rail has first conductors for forming a first power supply circuit and second conductors for forming a second power supply circuit. The support rail additionally has a converter unit for electrically coupling the second power supply circuit to the first power supply circuit. The second power supply circuit also has a first coupling element for electrically connecting a first lighting module and a second coupling element for electrically connecting a second lighting module. The result of this design of the second power supply circuit is that a single converter unit is sufficient for converting a voltage for supplying power to the two lighting modules. In this way a particularly cost-effective and compact construction of the support rail becomes possible.
