1. Lighting A lighting device (1″) with a lamp housing (2″) and a lighting unit (3″),
wherein the lamp housing (2″) on a light output side (5″) thereof has a light emission area (7″) and the lamp housing (2″) on a side (11″) thereof opposite to the light output side (5″) has a curved, dome-shaped rear wall (13″);
wherein the lamp housing (2″) further includes a cylindrical wall section (52″, 56″) between the curved, dome-shaped rear wall (13″) and the light output side (5″) of the lamp housing (2″);
wherein the lighting unit (3″) is set up to emit light on a light output side (17″) thereof in order to transmit the light through the light emission area (7″) of the lamp housing (2″);
wherein the lighting unit (3″) comprises a heat sink (18″);
wherein the lighting unit (3″) on a rear side (19″) facing away from the light output side (17″) thereof has at least one device (23″), which is used to attach the lighting unit (3″) to a selectable point on the rear wall (13″) of the lamp housing (2″) by means of a magnetic force, as a result of which a beam direction (A) of the lighting unit (3″) can be adjusted in relation to the lamp housing (2″);
wherein the beam direction (A) of the lighting unit (3″) is adjusted by moving the rear side (19″) of the lighting unit (3″) along the curved, dome-shaped rear wall (13″) of the lamp housing (2″);
wherein the lamp housing (2″) has a cover element (26″), which is formed with the light emission area (7″) and is positioned to cover an opening (59″) in the lamp housing (2″) on the light output side (5″) which enables the lighting unit (3″) to be inserted into an internal space (12″) of the lamp housing (2″) through the opening (59″);
wherein the cover element (26″) for covering the opening (59″) is magnetically attachable;
wherein the cover element (26″) is configured to be fitted into the opening (59″) and has a central access opening that serves as a light emission opening (8″), the light emission area (7″) being formed with the light emission opening (8″); and
wherein the light emission opening (8″) is smaller than a maximum radial dimension of the lighting unit (3″), in a manner preventing the lighting unit (3″) from being introduced into the internal space (12″) and attached to the rear wall (13″) through the light emission opening (8″).
