Abstract (en)
[origin: WO2011009423A1] A light-emitting element (1) is equipped with a large number of light-emitting diodes (3, 4, 5, 6) which are arranged in a housing (2) and serve as light-emitting means. Said light-emitting diodes run anti-parallel to one another, to be precise preferably in units (7, 8), which each have two diode pairs (9, 10) that run anti-parallel to one another.
