Abstract
An all-around reflector for retroreflection of beams which comprises, as reflectors, triple prisms with round light entrance surfaces, wherein the triple prisms are arranged in a housing in such a way that their light entrance surfaces are part of the circumferential surfaces of the housing. The triple prisms are arranged in the housing in such a way that adjacent triple prisms contact, or almost contact, at a point inside the housing. The tips (corners) of the triple prisms lie in a plane extending vertical to the light entrance surfaces of the triple prisms wherein the axes of the triple prisms which intersect at a point are also located in this plane. Triple prisms which are located next to one another are oriented relative to one another so as to be rotated about their axes by 60°.
Claims8
A 360-degree all-around reflector for retroreflection of beams, comprising:
- a housing;
- triple prisms, as reflectors, with round light entrance surfaces, wherein the triple prisms are arranged in said housing in such a way that their light entrance surfaces are part of circumferential surfaces of the housing;
- said triple prisms being arranged in said housing in such a way that adjacent triple prisms contact at a point, or almost so contact, inside the housing;
- said triple prisms having tips or covers which lie in a plane extending perpendicular to the light entrance surfaces of the triple prisms;
- said triple prisms having axes and wherein the axes of the triple prisms which intersect at a point are also located in this plane;
- and
- triple prisms which are located next to one another being oriented relative to one another so as to be rotated about their axes by an angle of 60°.
