Description

  The present invention relates to a remote-control lighting system in which a lighting fixture is remotely controlled by a signal transmitted from a slave unit incorporating a human sensor.

  Conventionally, lighting fixtures that are turned on by detecting a person with a human sensor only when there is a person in the vicinity of the lighting fixture and turned off when the person is no longer in the vicinity are widely used from the viewpoint of energy saving (for example, Patent Document 1).

  In addition, if the lighting fixture is located in a different location with respect to the area to be detected by the motion sensor, the motion sensor is mounted at a different position from the lighting fixture and wired between the motion sensor and the lighting fixture. Is done. However, in this case, wiring is necessary, and when it is desired to change the position of the human sensor or the location of the corresponding lighting fixture, it is necessary to change the wiring each time, which is very inconvenient. Therefore, a remote control type illumination system is used in which a human sensor is attached to the child device and wirelessly communicates between the human sensor and the lighting fixture. However, in such a remote control type illumination system, since a communication time is required between the slave unit and the luminaire, the time for which the lamp of the luminaire is lit is delayed by the communication time.

  Further, when the lamp as a light source is a discharge lamp such as a fluorescent lamp, in order to light the lamp, the filament of the electrode is preheated first, and then a high voltage for starting discharge is applied to start the discharge, and the lamp is turned on. It is common to light up. This preheating time takes about 0.5 to 1 second.

The operation of a conventional remote-control lighting system that wirelessly communicates between the human sensor and the lighting fixture will be described with reference to FIG. The child device detects a person with a human sensor and transmits a signal for remotely controlling the lighting apparatus. The lighting fixture receives the signal, and if the signal is a lighting signal to the fixture, the lighting fixture is turned on to start preheating. After the preheating time, the lighting fixture turns on the lighting circuit to light the lamp. The communication time for transmitting and receiving signals varies depending on the communication method and procedure, but it takes 0.5 to 1 second. Further, when the lamp of the luminaire is a fluorescent lamp, the preheating time until the lamp is turned on. Take it. For this reason, it may take up to about 2 seconds from when the human sensor detects a person until the lamp is finally turned on. In this case, it may be assumed that the lamp is turned on after a person passes through the irradiation area of the luminaire and does not make sense for the luminaire.

The lighting circuit 12 and the preheating circuit 15 may be configured such that the lighting circuit 12 also serves as a preheating circuit as an integrated circuit configuration. Electric power is supplied from the power supply 16 to the lighting fixture 10.

  When the control unit 13 receives the signal 24 transmitted from the slave unit 20 by the receiving unit 14, the control unit 13 starts preheating the discharge lamp 11. The signal 24 is transmitted as a communication signal from the transmission unit 23 of the slave unit 20 to the reception unit 14 of the lighting fixture 10. The communication means for transmitting the signal 24 may be any communication means as long as it performs wirelessly such as radio waves and infrared rays.

  The preheating start of the remote control lighting system 1 will be described with reference to FIG. The human sensor 21 of the child device 20 generates a detection signal when detecting a person. The subunit control unit 22 processes the detection signal of the human sensor 21, and the transmission unit 23 transmits the signal 24 processed by the subunit control unit 22.
