The entire store is normally lit with the lighting load 3 in a stepped dimming state using a conduction angle determined by the phase shift circuit 13. When a visitor comes, the SCR 9 is driven by the output of the receiver 7 using the carrier signal of the transmitter, and the lighting load 3 is turned on 100%. here,
The present invention provides a plurality of resistors 11a, 1 with different resistance values.
By switching between 1b and 11c using a switch 15, the following features are achieved. That is, the resistance value is changed depending on the internal impedance of the lighting load 3, so that a constant dimming state is always maintained even for lighting loads 3 having different capacities. That is, for example, when dimming by half to 50% lighting, the dimming rate differs depending on the capacity (wattage) of the lighting load 3 (for example, an incandescent lamp), so each resistor 11a, 11b, 11c is inserted and connected by the switch 15. In this way, for example, modes such as 75W, 100W, and 150W can be provided, and the light attenuation rate of each capacity can be matched. Therefore, by setting the switch 15 according to the capacity of the lighting load 3, the resistors 11a and 11
By selecting the resistance values of b and 11c, the light attenuation rate can be changed. In this way, the phase shift circuit 1
3, the lighting load 3 is normally dimmed in steps, and when a visitor is detected, a carrier signal is transmitted through the power line 6, and the output of the receiver 7 is used to directly connect the triax 4 without going through the phase shift circuit 13. The lighting load 3 is turned on so that 100% of the lighting load 3 is lit.

る効果を奏するものである。 As mentioned above, the present invention consists of a main circuit consisting of a power supply, a lighting load, and a triac, and a first circuit that is driven by a carrier signal superimposed on a power line and supplies a signal current to the gate of the triac to fully light up the lighting load.
A signal is sent to the gate of the triac through a gate circuit, a phase shift circuit consisting of a plurality of resistors and capacitors having different resistance values, each of which is switched by a switch, and a trigger element that is turned on by the output of the phase shift circuit. Since it has a second gate circuit that supplies current and dims the lighting load in stages, the triax is normally dimmed via the second gate circuit at a conduction angle determined by the phase shift circuit. The lighting load is then turned on in a stepwise dimming state, and when a visitor comes, etc., the first gate circuit drives a triac using a carrier signal superimposed on the power line.
A dimming circuit that has a power saving effect when the lighting load is turned on at 100% and is in the normal stage dimming state, and also allows guests to switch from the dimming state to 100% lighting, so there is less discomfort for visitors. is obtained. In addition, a phase shift circuit is provided to dim the lighting load in steps, which is made up of multiple resistors and capacitors that have different resistance values and are each switched by a switch. During half-reduced dimming (lighting), the lighting load (e.g. incandescent lamps)
The dimming rate differs depending on the capacity (wattage) of the lamp, but by switching the switch to match the resistance value to the appropriate resistance value, in other words, changing the resistance value depending on the internal impedance of the lighting load, Even when the lighting load is dimmed in steps, the dimming rate of each capacitor can be matched, and therefore even lighting loads with different capacities can always maintain a constant step-by-step dimming state.
