IMPROVEMENTS IN OR RELATING TO LIGHT ASSEMBLIES

摘要

The present invention relates to a method for forming a light beam, and to a light assembly comprising at least one light source placed in conjunction with a fixed reflector, which reflector forms a beam of light into light forming means, which light assembly comprises a front lens, where the light forming means at least comprise a light deflecting means for changing the light angle of the light beam after passing through the front lens. The object of the invention is to achieve a light assembly, where major optical components are mechanically fixed in relation to a housing for achieving a light assembly, the mass centre of which changes only slightly during operation. This can be achieved, if the front lens has a central part that differs from the surrounding parts of the front lens, and where the light deflecting means in a first position concentrates the light beam into the central part of the front lens to generate a wide-angle light beam, and where the light deflecting means in a second position distributes the light beam over the entire front lens to generate a narrow-angle light beam, because of the internal light deflecting means, the front lens does not have to be movable with respect to the housing.
