A wireless communication device includes: a wired communication circuit which receives, through a wired connection, an operation signal for controlling each of luminaires from a management device which controls an operation of each of the luminaires; a radio communication circuit which converts the operation signal received by the wired communication circuit and transmits the converted operation signal to each of the luminaires over a radio wave; an infrared ray receiver which receives an infrared ray signal transmitted from outside; and a controller. When the wired communication circuit receives a signal having a predetermined pattern from the management device, the controller transitions to a state for receiving the infrared ray signal, and, based on the infrared ray signal transmitted from outside, transmits a signal relating to communication setting between the radio communication circuit and each of the luminaires to each of the plurality of luminaires via the radio communication circuit.

A controller included in a lighting control device causes a transmitter to transmit a dimming rate which is determined by schedule information stored in a storage when power saving is not instructed via a power saving instruction signal. When power saving is instructed via the power saving instruction signal, the controller calculates a dimming rate for causing a luminaire to emit light at a brightness lower than in the case of the dimming rate determined by the schedule information. When the calculated dimming rate is a dimming rate which causes the luminaire to emit light at a brightness lower than a predetermined dimming rate, the controller causes the transmitter to transmit the predetermined dimming rate.

A lighting control device that controls a lighting device includes: a brightness sensor that obtains brightness information indicating the current brightness of an illuminated surface illuminated by the lighting device; a controller that obtains the brightness information from the brightness sensor; and a transmitter that wirelessly transmits, to the lighting device, a control signal generated by the controller for controlling the lighting device. The controller determines a waiting time based on the brightness information and transmits the control signal to the lighting device via the transmitter after elapse of the waiting time from a predetermined time.

A lighting control device that controls a lighting device includes: a brightness sensor that obtains brightness information indicating a current brightness of an illuminated surface; a storage that stores a brightness target value for the illuminated surface; a controller; a receiver via which the controller receives an energy-saving signal; and a transmitter that transmits, to the lighting device, a control signal generated by the controller. When the energy-saving signal is not being received, the controller determines a dimming rate for the lighting device based on the brightness target value and the brightness information. When the energy-saving signal is being received, the controller determines an energy-saving brightness target value smaller than the brightness target value by multiplying the brightness target value by a predetermined rate and determines an energy-saving dimming rate for the lighting device based on the energy-saving brightness target value and the brightness information.

An automated roadway marker system that illuminates and provides warning and lane demarcation under poor visibility conditions utilizing IR beam-break transceivers where no deployment considerations need to be made for the first in a sequence, because each marker operationally establishes its linkage condition in an intermittently activated asynchronous pseudo-network. The devices are designed for extremely low power consumption, so that solar energy can be utilized as a power source. The markers can additionally be linked through radio frequency signals, and to provide a warning to mobile and stationary radio frequency receivers. Additionally, the markers can be illuminated via transmissions from mobile and stationary transmitters.
