Light emitting system, transmitting apparatus for use in light emitting system, and receiving apparatus for use in light emitting system

摘要

The invention relates to a light emitting system and transmitting apparatus and receiving apparatus to be used in the light emitting system. The transmitting apparatus has a first transmitting circuit that transmits a light emission data signal for setting a light emission condition by a signal other than light on a wireless basis and a second transmitting circuit that transmits a light emission start signal for starting light emission by light on a wireless basis. The receiving apparatus is either adapted to be connected to an illuminating apparatus that emits illuminating light or having such an illuminating apparatus. The receiving apparatus has a first receiving circuit that receives the light emission data signal by the signal other than light on a wireless basis, a second receiving circuit that receives the light emission start signal by light on a wireless basis, and a control circuit that performs a light emission preparation operation of the illuminating apparatus based on an output of the first receiving circuit that has received said light emission data signal and causes the illuminating apparatus to emit light based on an output of the second receiving circuit that has received the light emission start signal.
