Abstract (en)
[origin: EP1643473A1] The optical element for an alternating traffic sign comprises a longitudinal housing (5,15) in which there is a least one light source (3) around which at least two lenses (9,13) are arranged over one another in the longitudinal direction of the housing. The lenses regulate the rays' direction. The housing comprises a first housing section in which the light source and the collector lens (9) are fixed and a second housing section in which the stabilising lens (13) is fixed and is where the mounting of the element is achieved. The second housing section is mounted on to the first housing section, with the first housing section having a hollow chamber (31) in which the second housing section is fixed such as to achieve a stable fixture.
