摘要:
A luminaire for illuminating a space underneath a ceiling or a canopy (1) to which the luminaire (2,3) is attached. The luminaire (2,3) comprises a plurality of LEDs (31) positioned in a straight array, and an elongated convergent lens (30) which extends parallel to the array of LEDs (30). The array of LEDs (30) is located at a distance (D) from the plane of symmetry (33) of the elongated lens (30).
