摘要

The lighting device has lens array and a high speed light emitting diode chip (2) with multiple microlight emitting diodes (1). A microlens array (4) is attached on the light emitting diode chip to a distance of 0.1 millimeter to 0.5 millimeter. The microlens array is made of combination lenses (3) that are arranged with each other, where the combination lenses are directly assigned to the micro light emitting diodes.
