Light frame (100) for use with a visor (200), which light frame comprises a rigid frame part (110) arranged to be mounted about the periphery of a sight glass (210) of the visor, which frame part comprises at least three directed light sources (131-138,141-144), with respective light cones (131a-138a,141a-144a), arranged to illuminate the area in front of the sight glass during use, which light frame further comprises a voltage source arranged to power the light sources. The invention is characterised in that said light sources comprise at least two fixedly directed primary light sources (131-138), whose light cones (131a-138a) are directed towards one and the same point (139a, 139b) arranged between 20 and 80 cm in front of the sight glass during use, and in that said light sources further comprise at least one fixedly directed secondary light source (141-144), whose light cone (141a-144a) during use is not directed towards the said point.
