Patent number: 10045421Abstract: The disclosure is directed at a system, power supplied to a solid state lighting (SSL) device when an operational fault condition is sensed such as when the power level being supplied to the device is sensed to be meeting or higher than an expected or predetermined level. The system, method and apparatus provide a recovery aspect which means that the SSL device will not be automatically shut down (or power being supplied to the SSL device will not be immediately stopped) upon the discovery of the operational fault condition but will enter a recovery mode.Type: GrantFiled: January 24, 2017Date of Patent: August 7, 2018Assignee: LUMASTREAM CANADA ULCInventors: David Tikkanen, Kyle Hathaway
