Abstract (en)
[origin: EP1538059A1] The signal unit consists of a lamp and a first optical system (3), and a second optical system (6) between the two. The focal point (9) of the second system mainly coincides with the light entry-sided focal point of the first system. The lamp is an LED unit, e.g. single LED with a focusing lens to form the second optical system, or an LED matrix (7) with a number of mainly similar LED modules (8), which define a mainly circular light surface.
