Abstract
A lighting device, such as a light-emitting diode (LED) light source, may operate in an interim operable state to avoid and/or prevent undesirable characteristics in the light emitted by the lighting device (e.g., strobing and/or flickering of a brightness of the light and/or shifting or change of a color of the light). When operating in a normal state, the control circuit may determine if a measured value of a first operational characteristic (e.g., a forward voltage of an emitter of the lighting device) is outside of a range and operate in the interim operable state if the measured value of the first operational characteristic is outside of the range. When operating in the interim operable state, the control circuit may adjust a drive current for the emitter in response to a measured value of a second operational characteristic (e.g., a forward voltage of a detector of the lighting device).
