Abstract
An oven for cooking with light having wavelengths in the visible, near visible, and infra-red spectral ranges cooks food items for periods that are predetermined for given food items. When prolonged use of the oven increases the oven temperature, a thermistor detects the temperature increases and delivers a signal representing the increase to a microprocessor. The microprocessor is programmed to compensate for increases in the oven temperature by lowering the cooking time for a given food item below the predetermined period. Some of the heated air that accumulates in the oven is withdrawn by an evacuation device.
