DN05066/D - LED Failure Detector and Backup LED Design Circuit for Critical Lighting Applications
Projekt referencyjny przez: onsemi
DN05066/D - LED failure detector and backup LED design note uses HBL5006 LED shunt to serve multiple purposes. LED1 is the primary LED. This is the LED which operates from the time the lighting module is manufactured until the LED itself fails. When LED1 does fail, either as an open or a short, the circuit detects this and immediately switches in a backup LED, which is LED2. The logic of the HBL5006 device makes this near perfect continuity of the light output possible
