RELIABLE LIGHTING SYSTEM

摘要

A lighting system (1) and its applications are described that are suitable especially in the realm of lighting systems (1) with high power light emitting diodes (LEDs). The lighting system (1) comprises a control circuit (3) with a memory device (4) and a refresh circuit (10), and the refresh circuit (10) is adapted to prevent data loss of the memory device (4) due to the reduction of the retention time of the memory device (4) caused by the high operation temperature of the LEDs.
