Abstract (en)
[origin: EP0828112A1] The warning lights use a parabolic segmented mirror to produce bands of light (21,23) which then enter a dividing element (12). The dividing element (12) consists of alternate segments (18,20) each having a curved forward face to cause convergence to focal points (F) in a plane (P). A colouring element (22) is situated in the plane (P) and consists of alternate colour filters (28,30) which are respectively narrow and wide and coloured green and red. After passing through the filters the light is divergent and recombines to form white light as required by regulation.
