A lighting control device controls a turn-on state and a turn-off state of a lighting apparatus in a room where an air-conditioning apparatus is provided. In the lighting control device, a temperature sensing section is provided in the air-conditioning apparatus and senses temperature of the room to allow the air-conditioning apparatus to perform air-conditioning control such that the sensed temperature of the room lies within a preset temperature range. A temperature acquisition section acquires the sensed temperature. A determination section determines that a switching condition for switching the lighting apparatus has been met, when the acquired sensed temperature coincides, within a preset tolerance range, with a criterion temperature which is set separately from the preset temperature range on the basis of a body temperature of a person. A switching section switches the lighting apparatus between the turn-on state and the turn-off state, when determined that the switching condition has been met.
