摘要

An LED controller (11) judges whether a temperature sensor (21) is normal in accordance with measured temperature data and controls luminance of an LED (32) measured by an abnormal temperature sensor (21) in accordance with alternative temperature data instead of the temperature data measured by the abnormal temperature sensor (21).
