Description

Adapter for track mounted luminaire system and lighting arrangement Technical Field The present invention relates to the field of lighting arrangements, in particular for lighting purposes of buildings (e.g. the interiors thereof). The invention relates in particular to the field of track mounted luminaire systems. The present invention relates to an adapter for a track mounted luminaire system and a lighting arrangement comprising such an adapter. Background Various embodiments of track systems for lighting purposes are known. For example, systems have been proposed that integrate electrical conductors into rail profiles to provide a supply voltage. Such track mounted luminaire systems may, for example, comprise various types of luminaire inserts, such as spot light or linear luminaire inserts, wherein these inserts may also be combined. Adapters are known which can be introduced into the rail, take up operating currents and control signals via longitudinally extending conductors and serve to operate electrically connected functional elements, in particular lamp/lamp inserts. Such an adapter is described, for example, in AT 527 716 A1. The known adapters can be introduced into selectable positions along the track and the means of these adapters provided for this purpose can be brought into a detachable contact position, thereby ensuring a fixed electrical and mechanical connection. The requirements for the contact mechanism of such an adapter may, for example, relate to reliable contact, space-saving construction in a limited adapter body, ease of use, reduced number of required parts, avoidance of wear in long-term use, easy breaking capability, etc. In many cases, various known designs selectively take into account only a portion of the above aspects. For example, EP 3,544,127 A1 describes an adapter having movably arranged electrical contact elements which project by rotating a single camshaft, wherein the individual contact elements are each pushed into their projecting position by a cam. For example, WO 2021,939 A1 and EP 4,518,047 A2 describe a connection device for a lighting system with a charged track, in which an operating device with a slide and a rod performing a translational movement is provided. The displacement of the slider causes a translation of the rod and thus a rotation of the rotatably arranged body. The displacement of the slider exposes the electrical contact from the housing. AT 526,097A2 also describes an adapter for a track-mounted luminaire system, wherein the contact element can be moved between the contact position and the non-contact position by means of a movably arranged operating element. This patent describes that the contact element is arranged on a carrier rotatably mounted in the adapter housing and that a rotational movement of the carrier is caused by a displacement movement of the operating element. The linear, linear displaceability of the operating element, as in AT 526 a 097 A2, for example, has proven to be advantageous for the operability of the adapter. For example, such an operating element can be operated by an operator conveniently and without tools and enables reliable contact with the electrical conductor provided in the track. However, it has been found that relatively many individual components are required to convert linear sliding motion into rotational motion, which also entails considerable effort in assembling such an adapter. DE 2 210,516A describes another adapter for conductor tracks, which has retractable and extendable contact and holding members. The adapter has a movable slide with a driver for controlling retraction and extension of the contact and holding member. Disclosure of Invention Against this background, it is an object of the invention to provide an adapter which enables a detachable and reliable contacting of rail conductor means, which is easy to handle and at the same time can be produced with less effort and at lower costs. Accordingly, an improved lighting arrangement is also presented. According to the invention, this object is achieved by an adapter having the features of claim 1 and/or by a lighting arrangement having the features of claim 22. Accordingly, an adapter for a track mounted luminaire system is presented. The adapter is embodied for insertion into a track of a track mounted luminaire system. The track has conductor means with conductors, the adapter has contact elements, and in the inserted state of the adapter the individual conductors or selected conductors can be contacted by the contact elements. Each contact element has a contact portion that is movable to a contact position in which the contact portion protrudes from the adapter to electrically contact an associated one of the conductors, and a non-contact position in which the electrical contact of the contact element with the associated conductor is interrupted. In the adapter of the invention, each contact element has an elongated shape. The individual
