Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dimmer control system for controlling a lighting load by a radio signal, a radio transmission unit, and a radio dimmer.

[0002]

2. Description of the Related Art Conventionally, in indoor and outdoor lighting facilities such as a gymnasium, a concert hall, and a temporary event venue, a lighting dimmer is used to design a lighting intensity, and a signal input from the dimming desk via a signal line on a master unit is transmitted. A dimmer control system that controls a plurality of dimmers by converting a wireless signal into a wireless signal at a wireless master device and transmitting the wireless signal to a plurality of wireless slave devices has been put to practical use.

FIG. 8 is an explanatory diagram showing the operation of a conventional dimmer control system.

In FIG. 8, a light control console sequentially supplies simultaneous control signals to the light control units 1, 2, 3, and 4 as control data signals to a wireless master device. The wireless master device converts the simultaneous control signals from the light console to the light controllers 1, 2, 3, and 4 into wireless signals in the order in which they are supplied, and transmits the wireless signals to the wireless slave devices. The wireless slaves sequentially demodulate the simultaneous control signals addressed to the dimmers 1, 2, 3, and 4 from the wireless signal from the wireless master, and supply the demodulated signals to the dimmers 1, 2, 3, and 4. As a result, the dimmers 1, 2, 3, and 4 control the first to fourth lighting loads, for example, control the brightness of the first to fourth lighting lamps. Thus, by operating the light control console, it is possible to control the four light control devices arranged at a distance almost simultaneously in a human sense.

However, in such a conventional dimmer control system, there is no problem when the number of dimmers is small, but when controlling a large number (for example, 50) of dimmers, the control data signal is first transmitted. There is a time lag between the transmitting dimmer and the dimmer that finally transmits the control data signal, which can be clearly confirmed by human senses before the control data signal is transmitted. The effect of the effect using was reduced.

Further, in the conventional dimmer control system, the reception state between the wireless master unit and the wireless slave unit cannot be determined without actually turning on the lighting equipment which is a lighting load. In addition, it took time to determine the installation position of the antenna of the wireless handset.

Further, in the conventional dimmer control system, when one antenna is used for the wireless master unit, the position of the antenna of the master unit and the antenna of the slave unit and the influence of surrounding humans cause the influence of the surroundings. In many cases, the wireless signal transmitted from the slave cannot be received by the slave unit. In response to this, a wireless master device in which a plurality of transmitting antennas are attached to a wireless transmitting unit has been developed.

FIG. 9 is a block diagram showing a conventional wireless master unit provided with a plurality of transmitting antennas.

[0009] Referring to FIG.
Is composed of a control data receiving unit 302, a control unit 303, a wireless transmission unit, and N wireless transmission units 304-1 to 304-N.

[0010] Input terminal 305 of wireless transmission unit 301
, A control data signal is input from the control console via the parent device side signal line. The control data signal input from the input terminal 305 is received by the control data receiving unit 302, changed to a predetermined format, and supplied to the control unit 303. The control unit 303 includes N wireless transmission units 304-1 to 304-
N is selected one by one in order and a control data signal is output. The output sides of the N wireless transmission units 304-1 to 304-N are connected to a plurality of transmission antennas 307-1 to 307-N via a plurality of output terminals 306-1 to 306-N, respectively. When the control data signal is supplied from the control unit 303, the wireless transmission units 304-1 to 304-N perform modulation and amplification for wireless communication, and transmit the modulated signals to the transmission antennas 307-1 to 307-N, respectively. To output as a wireless signal.

According to such a radio transmission unit, a plurality of antennas can be selected and a control data signal can be transmitted as a radio signal. However, in order to modulate and amplify the control data signal, a plurality of transmission antennas are required. The same number of wireless transmission units are required, increasing the manufacturing cost.

Further, in the conventional dimmer control system,
A cable is used to connect the wireless slave unit and the dimmer, which are separate bodies, but when the luminaire is placed on the ceiling, it takes time to install the cable. This was more noticeable when lighting fixtures were added later.

[0013]

In the above-mentioned conventional dimmer control system, there is no problem when the number of dimmers is small, but when a large number of dimmers are controlled, a control data signal is transmitted first. Between the dimmer and the dimmer that finally sends the control data signal, there is a time difference that can be clearly confirmed by human senses before the control data signal is sent, and such lighting was used. The effect was reduced. In addition, the reception state between the wireless master device and the wireless slave device does not have to be turned on without actually turning on the lighting equipment that is the lighting load, and is used to determine the installation positions of the antennas of the wireless master device and the wireless slave device. It took time. Further, when a plurality of transmission antennas are provided in the wireless master device, the same number of wireless transmission units as the plurality of transmission antennas are required, which increases the manufacturing cost. Furthermore, a cable is connected between the separate wireless slave unit and the dimmer, but when the lighting equipment is arranged on the ceiling, it takes time and effort to install the cable.

Accordingly, an object of the present invention is to provide a dimmer control system capable of controlling a large number of dimmers simultaneously. It is another object of the present invention to provide a dimmer control system capable of easily confirming a reception state between a wireless master device and a wireless slave device. It is another object of the present invention to provide a wireless transmission unit in which a single wireless transmission unit can use a plurality of transmission antennas for transmission.
