Abstract

The light has an elongated housing symmetrical wrt. a vertical plane, transparent for downward light emanation and open at the top. Two light tubes (28) are mounted in the housing at equal distances on both sides of the centre plane. At least one reflector (30) is mounted in the housing near each light tube to deflect the light at least partly upwards. Each reflector is a holed plate with a vertical section (32) on one side of the light tube, an approximately horizontal section (34) above the tube and a third section (36) inclined upwards from the centre plane.
