Abstract
Systems and methods for detecting an incorrect load and preventing powering of that load, until a load change is detected, are disclosed. An incorrect load can be removed and a newly attached valid load can be operated without requiring a reset. A power supply or driver system for a lighting system including one or more solid state light sources includes the systems and methods. The power supply or driver system includes a processor and memory arrangement configured to detect whether a load is operable or non-operable while still being responsive to a new load being attached at any time, and to prevent the system from checking the same load more than once. These may be used in conjunction with features like auto-recovery, restart after faults, and load-hot-plug capability, while perhaps simultaneously reducing cyclical flashing of light output.
