Abstract (en)
[origin: EP1873449A1] The ceiling light has a heat radiating light source provided under a glass dome (3) of a base plate (1). An air inlet connecting piece (7) is guided into an interior of the ceiling light. An admission region (8) is formed in a heat storing manner and an end region (9) is formed in a heat rejecting manner proximate to a smoke detector (10) and/or a smoke sensor for causing a temperature difference along the air inlet connecting piece for a chimney effect, where the admission region faces a room that is to be monitored.
