Inspection area and luminaire for same

摘要

A luminaire (20) to illuminate an article to be visually inspected for surface defects includes a housing (22) having an opening in a forward face thereof. At least one elongate light source is accommodated by the housing. At least one linear reflector (70) is also accommodated by the housing. The at least one linear reflector has at least one forwardly directed, angled reflective surface (90) that directs light emitted by the at least one elongate light source such that the luminaire projects light onto a specular surface of an article being inspected resulting in a plurality of laterally, spaced images of the at least one elongate source being reflected by the specular surface.
