The lamp unit has an elongate lamp housing (14) which is symmetrical to its vertical longitudinal centre plane (26), which screens the greater part of the downwards directed light. A pair of light tubes (28) lie on either side of the vertical longitudinal centre plane, with associated reflectors (30) angled upwards relative to the centre plane from a point (32) in the upper half of the light tube periphery. Pref. each reflector has a convex curvature on the side facing the vertical centre plane and a concave curvature on the side facing the light tube, with a lipped top edge (36) bent in the direction of the light tube. |
