Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection type lighting apparatus wiring system in which a plurality of lighting apparatuses each having a plurality of fluorescent lamps are connected in a column and connected to each other by connecting power supply lines of the lighting apparatuses adjacent to each other. It is about.

[0002]

2. Description of the Related Art Conventionally, as a lighting facility for a large store or office, a large number of luminaires each having a plurality of (for example, two) fluorescent lamps are installed in a column, and the power supply lines of the luminaires adjacent to each other are respectively installed. It is known that power is supplied (so-called feed wiring) to each column by connecting them, and a required number of the same components are arranged and illuminated. However, in such lighting equipment, if you try to selectively turn off a part of the lighting in order to adjust the illuminance and save energy, you must turn off all the lighting fixtures installed in a column, which is the minimum unit of the power supply system. Since it is necessary to obtain a uniform illuminance distribution,
In addition, there is a drawback that many stepwise lighting patterns cannot be created.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned drawbacks of the conventional device, and to create many stepwise lighting patterns when selectively turning off a part of the illumination. It is an object of the present invention to provide a wiring system for a connection type lighting fixture that can achieve a uniform illuminance distribution.

[0004]

In order to solve the above-mentioned problems, the wiring system of the connecting type lighting apparatus of the present invention is such that a plurality of fluorescent lamps each having a plurality of fluorescent lamps installed in parallel are connected in series. Installed, and connect the power supply lines of the fluorescent lamps arranged in columns of adjacent lighting fixtures to each other so that each column of all fluorescent lamps arranged in a column has an independent power supply system. ing.

[0005]

Since it is possible to control the lighting of each of the fluorescent lamps arranged in tandem, in order to selectively turn off a part of the whole illumination, for example, one in five rows and one in four rows. Many stepwise lighting patterns such as one row in one row or three rows can be created, and rows of fluorescent lamps to be turned off can be finely dispersed, so that a uniform illuminance distribution can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wiring system for a connection type lighting apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view in which a plurality of connection type lighting fixtures are connected in a column and installed.
FIG. 2 is a perspective view of each of the connection type lighting fixtures. The connection-type lighting fixture 1 has two fluorescent lamps 2a and 2b installed in parallel on the lower surface thereof, and includes terminal blocks 3a and 3b to which the sockets of the fluorescent lamps 2a and 2b are connected, respectively. Wirings for connection are led out from 3b toward the front and the rear, respectively. A large number (for example, ten) of the same type of concatenation type lighting fixtures 1 are installed in series so that all the fluorescent lamps 2a are arranged in a row, and all the fluorescent lamps 2b are arranged in a row. Has become. Then, a plurality of the same connection type lighting fixtures 1 connected in a column and installed in parallel are installed in parallel.

Connectors 4a and 5a are provided at the tips of the two connecting wires that are led out from the terminal block 3a to the front (to the left front side in the figure) and to the back (to the back right side in the figure), respectively. The connector 4a provided on the front side is the terminal block 3a of the lighting fixture 1 adjacent to the front side.
Connector 5 for connection wiring that is led out from the rear
In addition, the connector 5a provided on the rear side a is connected to the connector 4a of the connecting wiring that is led out forward from the lighting fixture 1 adjacent to the rear side. Further, connectors 4b and 5b are similarly provided at the tips of the two connecting wires that are led out from the terminal block 3b toward the front and the rear, respectively, and the terminal blocks of the lighting fixtures 1 adjacent to each other in the front and rear are also provided. Connectors 5b and 4 for connecting wirings, which are respectively led out to the rear and the front from 3b
b respectively.

The connector 4a for connecting wiring, which is led out forward from the terminal block 3a of the foremost lighting fixture 1, is connected to the power feeding inverter 6a of the "a" system, and its terminal block 3b.
The connecting wiring connectors 4b derived from the front are connected to the power feeding inverters 6b of the "b" system, respectively, and all the fluorescent lamps 2a arranged in a line are fed by the power feeding inverter 6a and all arranged in a line. Fluorescent light 2
b is fed by the power feeding inverter 6b. Therefore, if the operation of the power feeding inverter 6a is stopped, all the fluorescent lamps 2a of the "a" system are turned off, and similarly, if the operation of the power feeding inverter 6b is stopped, all the fluorescent lights of the "b" system are fluorescent. The lamp 2b is turned off.

For example, when it is desired to perform lighting control so as to save energy by 20%, one out of every four rows of the fluorescent lamps 2a and 2b of the connection type lighting apparatus 1 arranged side by side. It is only necessary to turn off the light, and to save energy by 25%, it is sufficient to turn off every third row every three rows. In addition, although the said Example demonstrated the case where each lighting fixture 1 was equipped with two fluorescent lamps, it is not restricted to this, For example, three fluorescent lamps, four, ... The same is true even when installed in.

[0010]

As described above, according to the wiring system of the connection type lighting apparatus of the present invention, since the lighting control can be performed for each row of the fluorescent lamps arranged in the vertical row, many stepwise lighting patterns are provided. Since it can be created and the rows of the fluorescent lamps to be turned off can be dispersed, it is possible to obtain a uniform illuminance distribution.
