Common Fault Handling Methods For Solar Street Lights

Common Fault Handling Methods For Solar Street Lights

many solar street lamps use dot matrix led light sources. in addition to the quality problems of the led light sources themselves, some lamp beads will cause this situation. the solution is to replace the corresponding lamp bead, solder it firmly or replace the entire lamp head.

Detecting And Managing Faults In Led Lighting Electronic

managing faults first requires their detection, the most basic step for maintenance of lighting system functionality. with leds, voltage is the most easily measured parameter for detecting an individual led s status. used for fault sensing, the on state led voltage serves to detect either open or shorted leds.
