Abstract

A light device comprises an elongated light guide () and a LED source () seated in the light guide entry part () for emitting the light beam into the light guide (). The entry part of the light guide comprises mutually intersecting parts of at least two ellipsoids () arranged with their main axes () next to each other. The LED light sources are fitted in the first focuses () of the ellipsoids for emission of light beams and their reflection from the elliptic walls () thereof to the second focuses () thereof, laying inside the light guide in different distances from the first focuses. The distance between the first focus () and the second focus () of the first ellipsoid () preferably equals at least 1.5 times the distance between the first focus () and the second focus () of the second ellipsoid ().
