Abstract

The invention relates to a lighting device (1; 1′; 1″; 101; 101′) with a lamp housing (2; 2′; 2″; 102; 102′) and a lighting unit (3; 3′; 3″; 103; 103′). The lamp housing has a light emission area (7; 7′; 7″; 107; 107′) on a light output side (5; 5′; 5″; 105; 105′) thereof and on a side (11; 11′) facing away from the light output side (11; 11′; 11″; 111; 111′) thereof has a curved, dome-shaped rear wall (13; 13′; 13″; 113; 113′). The lighting unit is set up to emit light on the light output side (17; 17′; 17″; 117; 117′) thereof in order to emit the light through the light emission area of the lamp housing. The lighting unit has at least one device (23; 23′; 23″) on a rear side (19; 19′; 19″; 119; 119′) facing away from the light output side (17; 17′; 17″; 117; 117′); 123; 123′) which can be used to attach the lighting unit in a selectable location on the rear wall (13; 13′; 13″; 113; 113′) of the lamp housing using a magnetic force, thereby enabling adjustment of the beam direction (A) of the lighting unit in relation to the lamp housing.

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″).
