Abstract:
1. An appliance having a cooktop, comprising: a light emitting device located proximate to a burner assembly of the cooktop, the burner assembly comprising one or more burners, the light emitting device configured to emit light at a light intensity level; and a controller configured to receive a signal indicative of a temperature in a region proximate the light emitting device, wherein the controller is configured to adjust a driver signal supplied to the light emitting device based on the signal indicative of the temperature in the region proximate to the light emitting device using pulse width modulation of the driver signal; wherein the signal indicative of the temperature in the region proximate to the light emitting device is based on an anticipated temperature profile of the light emitting device, wherein the anticipated temperature profile of the light emitting device is determined based on a transfer function correlating temperature to a selected power level for the burner assembly and a time period the burner assembly is ignited.
