Title:
SIGNAL INDICATOR LAMP SYSTEM AND SIGNAL INDICATOR LAMP THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/078771
Kind Code:
A1
Abstract:
Multiple signal indicator lamps 1A-1E are communicably connected via a network 3. Each of the signal indicator lamps 1A-1E is provided with a display part 12 that is capable of performing variable display. In addition to having the display part 12 perform variable display in response to an input signal inputted from input signal lines 8A-8E, the signal indicator lamps 1A-1E are capable of performing a mirroring operation as well. For example, the signal indicator lamp 1A is capable of simulating a display state of the signal indicator lamp 1E. In that case, when the input signal inputted from the input signal line 8E changes, the signal indicator lamp 1E transmits input information corresponding to the changed input signal to the signal indicator lamp 1A via the network 3. Further, every time a predetermined standby time elapses, the signal indicator lamp 1E periodically transmits input information corresponding to the latest input signal to the signal indicator lamp 1A. The signal indicator lamp 1A performs display that corresponds to the received input state.
