Abstract (en)
[origin: EP2226551A2] The optical element (2) has two longitudinal side reflectors (4) and transverse reflectors (5) arranged between the side reflectors. The distance of the transverse reflectors corresponds to the distance of two neighboring light emitting diodes (3) or light emitting diode cluster. The transverse reflectors are formed in V-shape. An independent claim is also included for a light delivery arrangement.
