A lighting device includes a thermal sensor, power converter circuits and a control circuit. The thermal sensor is configured to measure an internal temperature of a case. The power converter circuits are housed in the case and configured to be connected with different types of light sources, respectively. The control circuit is housed in the case and has priorities that are provided with respect to the different types of light sources according to their respective types. The control circuit is configured to, when the internal temperature is greater than a threshold, control the respective outputs of the power converter circuits so as to preferentially decrease an output for a light source corresponding to a first priority.
