LIGHT-EMITTING MODULE DEVICE, LIGHT-EMITTING MODULES USED IN SAID DEVICE, AND LIGHTING FIXTURE PROVIDED WITH SAID DEVICE

摘要

Disclosed is a light-emitting module device (1) provided with: a power line (3) that feeds power to light-emitting modules (2); and a signal-generating circuit (43) that generates a control signal. The power line (3) is shared among a plurality of light-emitting modules (2) and has switches (31, 32) that turn the flow of power to each light-emitting module (2) on and off. The signal-generating circuit (43) controls the switches (31, 32) individually. Said control consists of on periods when the light-emitting modules (2) are turned on and off periods when the light-emitting modules are turned off (2), during which, when there is a control signal to be sent, said control signal is superimposed on the supplied power. Since control signals are superimposed on the power supplied to each light-emitting module (2), the light-emitting modules (2) can be controlled individually. The power line (3) can also double as a communication line, and furthermore, since the power line (3) is shared among a plurality of light-emitting modules (2), it is possible to reduce the amount of wiring.
