Abstract
A LED lighting device includes a temperature sensitive component having a temperature limit. A driver controls current delivered to the at least one LED and includes a temperature sensor for determining a temperature of the driver. A controller stores a correlated temperature limit of the driver, the controller controls the driver to reduce the current delivered to the LEDs when the correlated temperature limit is reached. The correlated temperature limit is the temperature of the driver when the temperature of the temperature sensitive component reaches its temperature limit.
