Abstract

A light-emitting diode array is disclosed which has two light-emitting diodes which are connected in antiparallel with one another, and a power supply which is suitable for energizing the light-emitting diodes independently of one another in the forward direction. In addition, an optical recording apparatus and a method for the pulsed operation of a light-emitting diode are disclosed.
