Also, even if the module is manufactured with the above dimensions, there is a limit to its size to accommodate the switch box, and since it is attached to the switch box, there is a limit to its heat dissipation ability, so when it is 100% lit. There was a problem that the entire vessel became hot.

Furthermore, since the operating section and the light control section are integrated, and there are restrictions on the dimensions of the device as described above, there is a limit to the load control capacity. The present invention has been made in view of the above-mentioned problems, and its purpose is to separate the operation section, which requires wall mounting, from the dimmer unit, so that the dimmer unit can be integrated into the dimmer unit. In addition to being free from body size constraints, by installing the dimmer unit inside an electrical installation panel, etc., it is possible to improve heat dissipation efficiency and increase load control capacity, and it also requires wall mounting. An object of the present invention is to provide an incandescent lamp dimmer whose operation part can be downsized.

The dimmer unit is equipped with a system for sending a setting signal of the dimming setting means and an operation signal of the power supply operation means from the operation section.

[0006]The installation dimensions of the dimmer unit are set to dimensions that correspond to the dimensions standard for the internal device installed in the panel,
It is preferable that the body size of the operation part is formed to have one module size, which is the standard module size of a general wiring device, and that the body is provided with locking attachment means compatible with a mounting frame for mounting a switch box.

[0007]

[Operation] According to the present invention, the dimmer unit and
By installing the dimmer unit separately from the control panel and installing it inside a panel such as an electrical equipment panel, which has higher heat dissipation efficiency than installing it inside the wall, it is possible to reduce the temperature rise of the device when it is turned on at 100%. The light control unit can be freed from constraints on the dimensions of the device, and the heat dissipation efficiency can be improved depending on the installation location, making it possible to increase the load control capacity.

Furthermore, since the operating section can be manufactured independently, it is possible to downsize the operating section, thereby reducing the space required for mounting it on a wall. This is particularly advantageous in saving installation space when multiple dimmers are operated together. In addition, the operation part is formed of a single module with standard module dimensions for general wiring equipment, and the body is equipped with locking mounting means compatible with the mounting frame for mounting a switch box. Similarly, installation can be done using advance wiring.

Control terminals 421 are provided which read the control data CD of the time division multiplexed transmission signal Vs when the addresses match, and individually control the load relays RY11 in accordance with the control data CD.

For example, relay contact r1 of one of the load relays RY1 of the control terminal 421 is connected to the dimmer unit 2.
The incandescent lamp L in the dimming state can be turned on and off by turning on and off the relay contact r1 of this load relay RY1.

In the shape, signal line 41
When a current mode interrupt signal Vi due to a short circuit is sent from a monitoring terminal, for example 43, the transmission unit 4
0 sequentially accesses the monitoring terminals in groups according to the group address set in each group, and the monitoring terminal 43 that has caused the interruption transmits its own address data as a reply signal when the group to which it belongs is accessed. This reply signal is transmitted to the transmission unit 40 as a current mode signal due to the short circuit of the signal line 41 during the reply waiting period WT set in the time division multiplex transmission signal Vs. The transmission unit 40 transmits a time division multiplex transmission signal Vs for accessing the monitoring terminal 43 based on this address data, and causes the monitoring terminal 43 to send back monitoring information of the switch operation as a reply signal.

Based on this reply signal, the transmission unit 4
0 accesses the corresponding control terminal device, in this case 421, and transmits a time division multiplexed transmission signal Vs having control data CD for reversing the operation of the load relay RY1. The control terminal device 421 reverses the operation of the load relay RY11 based on the control data CD of the time division multiplexed transmission signal Vs, and turns on or off the relay contact r1. The power supply to the dimming unit 2 can be turned on and off by this on/off operation. Furthermore, CS in Figure 7
