Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting system and a lighting fixture used in this system, and more particularly to wirelessly controlling a lighting fixture connected to a wiring duct.

[0002]

2. Description of the Related Art Conventionally, it is known to directly and wirelessly control a plurality of lighting devices connected to a wiring duct.

[0003]

However, in the prior art, since commercial AC power is directly supplied to the wiring duct,
Each lighting fixture connected to the wiring duct requires a step-down transformer or a rectifier that generates a DC power source to be supplied to the control unit for wireless control, and the lighting fixture becomes large in size, which is extremely disadvantageous in terms of cost. A lighting system using a wiring duct is mainly used for store lighting and requires a large number of spotlight type lighting fixtures, and it is fatal to increase the size of such lighting fixtures.

Therefore, the present invention solves the above problems and
An object of the present invention is to provide a small and inexpensive lighting system for wirelessly controlling a lighting device connected to a wiring duct, and a lighting device used in this system.

[0005]

Means for Solving the Problems The present invention includes the following (1)-
It is configured as in (5).

(1) A direct current power source, a wiring duct connected to the direct current power source, a controller connected to the wiring duct and operated by the direct current power source, including a receiver for a wireless remote control signal, and a lamp. A lighting system including a lighting fixture.

(2) A DC power supply, a wiring duct connected to the DC power supply, an adapter connected to the DC power supply and operated by the DC power supply, and having a control unit including a wireless remote control signal receiving unit, A lighting system having a lamp connected to the adapter and having a lamp controlled by the control unit.

(3) The illumination system according to (1) or (2), wherein the DC power supply has an overcurrent limiting function.

(4) A lighting device which is connected to a wiring duct to which DC power is supplied and is operated by the DC power, and which includes a control unit including a wireless remote control signal receiving unit and a lamp.

(5) An adapter which is connected to a wiring duct to which a DC power source is supplied and is operated by the DC power source and which has a control unit including a wireless remote control signal receiving unit is required. A luminaire with a lamp controlled by the department.

[0011]

According to the present invention, since the DC power is supplied to the wiring duct, the step-down transformer and the rectifier are unnecessary for each lighting fixture or each adapter connected to the wiring duct. That is, the control unit including the wireless remote control signal receiving unit of the lighting fixture or the adapter can be operated by the DC power supply provided collectively.

When an incandescent lamp is used as the lamp, a large inrush current flows when the power is turned on and a large current flows due to arc discharge of the filament even at the end of the life. Therefore, the lamp opening / closing means included in the control unit. However, since it is easy to provide the DC power supply with the current limiting function, the opening / closing means may have a relatively small capacity.

[0013]

Embodiments of the present invention will be described with reference to the drawings.

1 and 2, a DC power supply 1 and a DC power supply 1
Illumination including a wiring duct 2 connected to the wiring duct 2 and a lighting unit 7 connected to the wiring duct 2 and operated by a DC power source 1 and including a control unit 5 including a receiving unit 4 of a wireless remote control signal 3 and a lamp 6. The system is shown.

More specifically, a commercial AC power supply (not shown) is input to the DC power supply 1, which is converted into a low voltage DC of, for example, DC 12V by a step-down transformer or a rectifier and is supplied to the wiring duct 2 all together. The lighting fixture 7 includes a plug 8 connected to the wiring duct 2, a main body 9, a hood 10, and a lamp 6, and the main body 9 includes a wireless remote control signal 3
The control unit 5 including the receiving unit 4 of the
Facing the outside. The DC power supply 1 and the wiring duct 2 are fixed to the ceiling 11, and the lighting fixture 7 is detachably connected to the wiring duct 2 with a plug 8.

The control section 5 will be described in detail. The DC voltage of 12V DC supplied from the wiring duct 2 to the lighting fixture 7 through the plug 8 is stepped down to 5V DC by the constant voltage circuit 12 such as a Zener diode and controlled. It is supplied to the part 5. Of course, if the voltage required for the control unit 5 and the voltage of the wiring duct 2 are equal, the constant voltage circuit 12 is not necessary. In the control unit 5, the wireless remote control signal 3 received by the reception unit 4 is input to the CPU 14 via the detection amplification unit 13 and signal processed, and the lamp 6 is blinked or dimmed by the opening / closing means 15 such as a transistor. .. Channel SW1
6 is provided so as to be operable from the outer surface of the lighting fixture 7, and the wireless remote control signal code that can be received when the switch is switched is different. Accordingly, if the channels SW16 of the luminaires 7 provided in large numbers are appropriately set to be switched and set, the luminaires 7 provided in large numbers can be selected and controlled, and switching of illumination scenes can be finely and easily handled.

The wireless remote control transmitter 17 shown in FIG.
Is a channel SW18 corresponding to the channel SW16 on the side of the lighting fixture 7, a dimming operation unit 19, a scene selection unit 20,
A blinking operation unit 21 and the like are provided, and during normal use, the scene selection unit 20 can be operated to control the illumination scene by each lighting fixture 7 to the set scene pattern.

Next, another embodiment of the present invention will be described with reference to FIG. 4. The wiring duct 2 connected to the DC power source 1 and the DC power source 1 connected to the wiring duct 2 are operated. And the adapter 22 having the above-mentioned control unit 5 including the receiving unit 4 for the wireless remote control signal 3, and the adapter 22.
And a luminaire 23 with a lamp 6 connected to and controlled by the control unit 5 is shown.

More specifically, the adapter 22 includes a plug 8 connected to the wiring duct 2 and the above-mentioned control section 5 including the receiving section 4 for the wireless remote control signal 3 and the channel SW16. Lighting equipment 2
The plug 24 of No. 3 is detachably connected.

According to the configuration described above, since the DC power supply 1 is supplied to the wiring duct 2, the step-down transformer and the rectifier are unnecessary for each lighting fixture 7 or each adapter 22 connected to the wiring duct 2. That is, the control unit 5 including the receiving unit 4 for the wireless remote control signal 3 can be operated by the DC power supply 1 provided collectively. Thereby, the lighting fixture 7 or the adapter 22 can be provided in a small size and at low cost.

When the lamp 6 is an incandescent lamp,
Since a large inrush current flows when the power is turned on and a large current flows due to arc discharge of the filament even at the end of life, a large-capacity opening / closing means 15 for the lamp 6 included in the control unit 5 is required. Since it is easy to give the DC power source 1 a current limiting function, the opening / closing means 15 may have a relatively small capacity.

[0022]

As described above, according to the present invention, it is possible to provide a lighting system for wirelessly controlling a lighting device connected to a wiring duct and a lighting device used for this system in a small size and at a low cost. It has the effect of being very useful for lighting in stores.
