Luminaire element for an inspection tunnel, luminaire strip, and inspection tunnel

A luminaire element for checking glossy surfaces, in particular painted surfaces, the luminaire element comprising at least two stripe-like arrangements of light sources in a luminaire housing, the luminaire housing having at least two edge regions lying opposite one another along a longitudinal extent of the luminaire housing,

• wherein first and second stripe-like arrangements of the light sources extend along the longitudinal extent at the opposing edge regions, the first and second stripe-like arrangements separated by a center region having a reflector positioned between the first and second stripe-like arrangements, wherein the separation of the first and second stripe-like arrangements and light reflected from the first and second stripe-like arrangements via the reflector define a luminance profile with a lower radiant intensity in a central region separating first and second radiant intensity peaks, and wherein the luminance profile includes first and second external regions on opposite sides of the radiant intensity peaks, the external region having a lower radiant intensity than the central region.
