[Problems to be Solved by the Invention] In the above-mentioned conventional example, due to the heat generation of the phase control triac, the body dimensions are the standard module dimensions of general wiring equipment, and three modules, that is, the serial module dimension or the double module dimension It had to be made larger. 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 that requires wall mounting from the dimmer unit, so that the dimmer unit can be integrated into the dimmer unit. An object of the present invention is to provide an incandescent lamp dimmer that is free from size constraints, allows for increased load control capacity by improving heat dissipation efficiency, and makes it possible to downsize an operating section that requires wall mounting.

[0005]

[Means for Solving the Problems] To achieve the above object, the invention according to claim 1 provides a dimmer unit equipped with a phase control circuit inserted in series between an incandescent lamp load and an AC power source. and an operation section equipped with a dimming setting means for setting the degree of dimming of the dimmer unit and a power supply operating means for turning on/off the power supply to the dimmer unit, and the dimmer unit is connected to the lighting equipment. Alternatively, it may be installed on the ceiling, the operating section may be provided on the wall, and a system may be provided for sending setting signals from the dimming setting means and operation signals from the power supply operating means to the dimmer unit from the operating section.

[0006] It is preferable that the body size of the operating section is formed to have one module size, which is the standard module size for general wiring devices, and that the body is provided with locking attachment means compatible with the mounting frame for mounting the switch box.

[0007]

[Operation] According to the present invention, the dimmer unit and
By installing the dimmer unit separately from the control unit and installing it in the ceiling, where heat dissipation efficiency is higher than installing it inside the wall, or in the lighting equipment, it is possible to reduce the temperature rise of the device when it is 100% lit. 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.

The diac 23 becomes conductive. This conduction of the diac 23 causes the triac 22 to conduct, causing current to flow through the incandescent lamp load L and lighting it. The conduction phase angle of this triac 22 can be set by the variable resistor 10 that constitutes a time constant, and the lamp current of the incandescent lamp load L is controlled according to the conduction phase angle, so that the incandescent lamp load L changes from 100% lighting to , the lights can be dimmed between a predetermined percentage. The degree of dimming can be known from the display provided around the operating knob 17 and the degree of rotation of the operating knob 17.

While the triac 22 is conducting, current flows to the primary side of the current transformer CT via the power switch SW, and the light emitting diode LED lights up at the secondary side output, indicating that it is on. be done. Furthermore, TRIAC 22
