Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a lighting control system that collectively performs dimming control, fade-in, fade-out control, on/off control, etc. of multiple lighting loads of different types or with different dimming characteristics. .

0002

2. Description of the Related Art A conventional lighting control system of this type is shown in FIG. This lighting control system connects a base device 1 and a plurality of terminal devices 2 to which unique addresses are set using a transmission line 4, connects a plurality of lighting loads 3 to the terminal device 2, and uses the base device 1 to control the lighting. It performs operation control such as dimming control, fade-in/fade-out control, or on/off control of the load 3.

When the base unit 1 controls the operation of the lighting load 3, the base unit 1 sets the unique address of the terminal unit 2 that accesses the address data of the transmission signal, and
Send control data for operation control individually to the The terminal device 2 that receives this control data converts the control data into a control signal for the lighting load 3 and controls the operation of the lighting load 3. Here, in the case of this embodiment, since a plurality of lighting loads 3 are connected to each terminal device 2, the base device 1 can collectively control the operation of the plurality of lighting loads 3 via the terminal device 2. become.

[0004] In this lighting control system, power is supplied to each terminal device 2 and lighting load 3 from a power supply line 5, and each terminal device 2 sends a control signal for controlling the power phase in the lighting load 3. By giving the lighting load 3
Performs dimming control or fade-in/fade-out control. Further, a terminal device 6 is provided on the power supply line, and the terminal device 6 controls the supply of power to the terminal device 2 so that all the loads 3 can be turned on and off at once.

By the way, in this type of lighting control system, when lighting loads 3 of different types or having different dimming characteristics are connected to one terminal 2, there is a problem that the operation of each lighting load 3 cannot be controlled in the same state. there were. For example, connect a fluorescent lamp and an incandescent lamp as the lighting load 3,
A case where the lighting load 3 is dimmed will be explained. Here, the relationship between the phase control state (ignition angle) and light output of fluorescent lamps and incandescent lamps is shown in Figure 4, where A indicates the characteristics of the fluorescent lamp and B indicates the characteristics of the incandescent lamp. show. Now, if the light output of each lighting load 3 is set to 75%, as is clear from FIG. 4, it must be set to 2π/5 for fluorescent lamps and π/3 for incandescent lamps. However, in the case of this type of lighting control system, it is not considered that lighting loads 3 of different types or with different dimming characteristics are connected. However, it was not possible to control the light output to the same level.

Here, as shown in FIG. 5, there is a conventional lighting device in which a fluorescent lamp 13 and an incandescent lamp 14 are dimmed at the same time using the same operation unit (volume, etc.) 15. In the case of this lighting device, the dimmer 10 controls the lighting circuit 12 of the fluorescent lamp 13 to dim the light in response to a dimming signal from the operation unit 15, and the dimmer 11 dims and lights the incandescent lamp 15. However, even in the case of this lighting device, since the fluorescent lamp 13 and the incandescent lamp 14 have different dimming characteristics as shown in FIG. It was not possible to match the dimming levels of the lights 14.

[0007] Therefore, a lighting control system that has improved the above-mentioned problems has been proposed in Japanese Patent Laid-Open No. 164191/1981. In this lighting control system, the terminal device 2 has a function (for example, the light output of each lighting load 3 is
5%, the lighting angle is converted to a control signal of 2π/5 for fluorescent lamps and π/3 for incandescent lamps, and the dimming level is the same for both fluorescent lamps and incandescent lamps. function), and the lighting load 3 of the terminal 2 is set by setting means such as a switch.
The control data is converted accordingly.

[0008]

[Problems to be Solved by the Invention] However, in the case of this lighting control system, settings are required using a setting means according to the type of lighting load 3, and the setting is troublesome, and it is difficult to control the operation of various lighting loads 3. In this case, the terminal device 2 needed to store a large amount of data in order to convert control data into control signals. Moreover, in the case of this lighting control system, there is a problem that different types of lighting loads 3 or lighting loads 3 having different dimming characteristics cannot be connected to each terminal device 2. However, in this lighting control system, it is possible to use different types of lighting loads 3 or lighting loads 3 with different dimming characteristics as the lighting loads 3 connected to each terminal device 2, but in this case, the above problem becomes even more noticeable. Become.

The present invention has been made in view of the above-mentioned points, and its purpose is to control lighting loads of different types or with different dimming characteristics by using the same control data. It is an object of the present invention to provide a lighting control system that can control operations in the same way, does not require setting, and does not require storing a large amount of data in a terminal device.

0010

[Means for Solving the Problems] In order to achieve the above object, the present invention provides dimming control of lighting loads, fade-in control,
A base unit that performs operation control such as fade-out control or on/off control, a plurality of first terminal devices connected to the base unit via transmission lines and receiving control data from the base unit, and these first terminal devices. and a plurality of second terminal devices to which the lighting loads are individually connected and which receive control data from the first terminal device and convert the control data into control signals for the lighting loads, The second terminal device is formed integrally with the lighting circuit of the lighting load.

[0011]

[Operation] By configuring the present invention as described above,
Even if the same control data is sent from the main unit, the second terminal installed separately for each lighting load converts it into a control signal according to each lighting load and gives it to each lighting load. By providing a second terminal device for each lighting load, there is no need to configure settings to perform appropriate operation control for each lighting load, and the second terminal device is provided for each lighting load. The terminal device only needs to store data for operation control according to the corresponding lighting load.

0012

Embodiment FIGS. 1 and 2 show an embodiment of the present invention. In the lighting control system of this embodiment, the terminal device 2 of the conventional example shown in FIG.
The terminal device 2a is used for receiving control data from the base device 1 in the terminal device 2, and a plurality of second terminal devices 2b are provided for each lighting load 3, and the terminal device 2b is used to receive control data for the lighting load 3. is converted into a control signal. The second terminal device 2b is formed integrally with the lighting circuit 8 of the lighting load 3 (including the case where it is a single ballast). Note that the second terminal device 2b may be mounted on the same printed circuit board as the lighting circuit 8, or may be housed integrally in the same case. Also,
9 in the figure indicates a lamp such as a fluorescent lamp or an incandescent lamp. Furthermore, the other configurations are the same as those in FIG. 3.

[0013] The operation of this embodiment will be described below in the case where the lighting loads 3 connected to the respective terminals 2a are of different types or have different dimming characteristics, and the lighting loads 3 are controlled to dim. . For example, when an operation switch (not shown) for dimming control is operated, a transmission signal including dimming data is transmitted from the base unit 1 via the transmission line 4. The first terminal device 2a receives the transmission signal, and outputs dimming data to each second terminal device 2b when the address data of the transmission signal matches its own address. The second terminal 2b converts this dimming data into a control signal and supplies it to the lighting circuit 8 to dim the lamp 9. Here, in this embodiment, in the first terminal device 2a, the transmission processing section 21 shown in FIG. 2(a)
However, as shown in FIG. 2(b), a signal conversion section 22 is provided at the next stage of the transmission processing section 21, and the dimming data is converted into a DC signal. etc., and may be provided to the second terminal device 2b.

In the case of this embodiment, since the second terminal device 2b is provided for each lighting load 3, there is no need for setting to perform appropriate operation control for each lighting load 3, and each terminal device 2b is provided for each lighting load 3. The device 2b only needs to store data for operation control according to the corresponding lighting load 3, making it possible to perform extremely fine operation control that is suitable for each lighting load 3. Moreover, the first terminal device 2
When an output corresponding to the control data is obtained from a, each second terminal device 2b controls the operation of the lighting loads 3 all at once in parallel processing, so that the operation of each lighting load 3 can be controlled simultaneously. Although the above explanation deals with dimming control, it is possible to perform fade-in and fade-out control in the same way, and if the function of the terminal device 6 in FIG. 3 is provided in the second terminal device 2b. , on/off control is also possible.

By the way, in the above case, since addresses are individually set for each first terminal device 2a, signal transmission between the base unit 1 and the first terminal device 2a is performed in chronological order. , it may not be possible to control the operation of each lighting load 3 all at once. Therefore, in order to improve this point, if the address of the first terminal device 2a is made single and the control data can be sent from the main device 1 to each terminal device 2a at once, it is possible to The operations of the loads 3 can be controlled simultaneously.
