Abstract

An elongated luminaire for illuminating objects in front of the luminaire, comprising a plurality of side emitting LEDs (1) in only one straight array mounted on an elongated base plate (2). The base plate (2) carries two elongated reflectors (3) extending on either side of the array of LEDs (1) and parallel to the array of LEDs (1). Each reflector (3) has a reflecting surface (4) directed towards the array of LEDs (1).
