▎ 摘　　要

NOVELTY - The luminaire (1) has luminaire housing (2) and an illuminant element (3) that is provided with an illuminant (4). The illuminant element is partially accommodated in the luminaire housing and is movable relative to the luminaire housing to change a light emission direction of the illuminant. A heat conducting element (5) is provided to thermally couple the illuminant to the luminaire housing in each movement position of the illuminant element relative to the luminaire housing. A first coupling area (6) of the heat conducting element is flatly coupled to the luminaire housing. A second coupling area (7) of the heat conducting element is flatly coupled to the illuminant element. The heat conducting element is made of material that comprises copper or carbon, graphene or graphite or carbon nanotubes in combination with plastic. USE - Luminaire such as recessed luminaire, surface-mounted luminaire or pendant luminaire. ADVANTAGE - The thermal coupling to the luminaire housing enables reliable heat dissipation through the luminaire housing. The temperature increase within the luminaire housing is avoided or significantly reduced, which enables sufficient cooling of the light source and increases the range of uses of the luminaire, since the appearance of the luminaire to the viewer is essentially independent of the orientation of the lamp element due to the lamp element which is partially accommodated in the luminaire housing. The optimized cooling of the luminaire increases the service life and reliability, and reduces the maintenance effort for the entire luminaire. The mechanical coupling of the heat-conducting element enables safe and effective heat transfer to be achieved. The assembly effort and number of components used are reduced. The luminaire housing is inexpensive and easy to manufacture. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of the luminaire.
