Abstract: A luminaire (100) comprises an elongate support member (101) which carries at least one light source (102). The elongate support member extends lengthways between opposing end portions. Spacer elements (103) respectively extend from the opposing end portions and support a reflector canopy (104) which extends over the elongate support member. The at least one light source faces the reflector canopy. The reflector canopy is foldable in a direction normal to the lengthways extension of the elongate support member and/or is foldable in the lengthways direction together with the support member. Further provided is a modular ceiling comprising at least one said luminaire.

Abstract: Disclosed is a luminaire (100) comprising: a heatsink (10) comprising a rim (20) 5 having a first rim section (21), a second rim section (22) and an intermediate rim section (23) in between the first rim section and the second rim section; a first heatsink region comprising a mounting region (40) and a plurality of first fins (31, 32) extending from the mounting region to at least one of the first rim section and the second rim section; and a second heatsink region comprising a plurality of second fins (33) looping from the 10 intermediate rim section; a light module (110) mounted in the mounting region (40) and thermally coupled to the first heatsink region, the light module comprising at least one light engine (120) and a controller (140) for the at least one light engine; and a sensor (50) mounted on the second heatsink region, the sensor being communicatively coupled to the controller, the controller being adapted to control the at least one light engine in 15 response to a sensor signal from the sensor.
