LIGHTING APPARATUS AND LIGHTING SYSTEM

摘要

A lighting apparatus which is one of a plurality of lighting apparatuses each capable of performing wireless communication with a control device. The lighting apparatus includes: a light emitting unit; a controller which controls turn-on of the light emitting unit; and a communication unit configured to perform wireless communication with the control device to obtain correction time from the control device, the correction time being based on communication delay between the control device and each lighting apparatus. The communication unit further obtains a turn-on instruction for turning on the light emitting unit from the control device, and transmits a response to the turn-on instruction to the control device upon obtainment of the turn-on instruction. The controller turns on the light emitting unit after passage of a time period from when the response is transmitted to the device, the time period being calculated by subtracting communication latency from the correction time.
