Abstract: The present disclosure relates to a luminaire having a light generation device, a heat sink, a reflector and an intermediate element. The heat sink is pivotably coupled to the reflector about a pivot axis relative to said reflector. Light can be emitted into an inner space of the reflector by the light generation device. The intermediate element is mounted on the heat sink so that it can be moved relative to said heat sink and has a first section provided with a tooth system. The reflector has at least one second section provided with a tooth system. Engagement of the tooth systems of the first and second sections into one another counteracts pivoting of the heat sink relative to the reflector about the pivot axis. To pivot the heat sink relative to the reflector about the pivot axis, the tooth systems of the first and second sections can be disengaged.

Abstract: A modular system comprising track-mounted fixtures and track is described. In some embodiments, fixtures access electrical power through electrified railings recessed within a relatively narrow power slot of the track. Primary mechanical support of the fixture weight is optionally provided from a magnetic mounting surface surrounding the power slot. The track cross-section optionally provides mounting surface area on mounting wings, allowing a narrower slot housing. Optionally, secondary mechanical support provided within the slot comprises a deployable anchoring element which laterally expands into a receiving area. Optionally, deployment comprises rotation of the anchoring element. The anchoring element, in some embodiments, acts as a secondary mechanical support, preventing, for example, accidental detachment of the fixture from the slot, without preventing repositioning movements of the fixture along the slot, even when fully deployed.
