When the lamp is turned on and off in a short time, the lamp La is turned off for a short time T _{1 as} shown in FIG. 2B, but there is a time delay until the illuminance sensor 3 newly detects an illuminance change. When the operation switch 1 is turned on, the illuminance level of the unit 4 is the illuminance level at the dimming level L ₀ immediately before the light is turned off. Therefore, the main control unit 4 turns the control signal S _{1 on} and off. It is output to the unit 5, and the power supply opening / closing unit 5 is fully conducted. Therefore, the electric power supplied to the lamp La becomes approximately 100% of the rated value, and the lamp La is fully turned on.

(Third Embodiment) FIG. 14 shows a circuit block diagram of a third embodiment of the present invention. Since the basic structure is the same as that of the first embodiment, the same symbols are assigned to the common portions. The description will be omitted, and only the characteristic parts of this embodiment will be described. The present embodiment is characterized in that it is provided with a human body detection sensor 7 for detecting the presence of a human body and that the operation switch 1 is eliminated so that the commercial power supply AC constantly supplies power. As the human body detection sensor 7, a pyroelectric type (PIR type) sensor that detects heat rays emitted from the human body is used, but the present invention is not limited to this. When the human body detection sensor 7 detects the presence of a human body within the detection range, it outputs an ON detection signal to the main controller 4.

Next, the operation of the circuit of this embodiment will be described. When the human body detection sensor 7 now detects a human body and outputs an ON detection signal to the main control unit 4, the main control unit 4 determines that the illuminance L detected by the illuminance sensor 3 before the ON detection signal is input is the determination value L.
₁ above determines whether or not there, as long as luminance L as shown in FIG. 2 (a) the determination value L ₁ or more, to the power switching unit 5 sends control signals S ₁ to the power switching unit 5 are full energization . Therefore, the electric power supplied to the lamp La becomes approximately 100% of the rated value, and the lamp La is fully turned on. After that, as shown in FIG. 2B, when the human body detection sensor 7 no longer detects the human body and the human body detection sensor does not output the ON detection signal,
The main control unit 4 turns off the control signal S ₁ and turns off the power supply opening / closing unit 5. When the power supply opening / closing unit 5 is turned off, the lamp La
Will turn off.

Next, when the human body detection sensor 7 outputs an ON detection signal when the ambient illuminance is lower than the determination value L ₁ , the main control unit 4 detects the illuminance sensor 3 before the ON detection signal is input. Since the illuminance L that was being used is lower than the judgment value L ₁ ,
The control signal S ₂ is output to the dimming control unit 6. Dimming control unit 6
When the control signal S ₂ is received, outputs a phase control signal to the power supply opening / closing unit 5. In this case, the generation phase of the trigger signal which is the phase control signal is gradually changed. The phase of the power supply opening / closing unit 5 is controlled according to the generation phase of the trigger signal, and the lamp La
The power supply of is increased at a predetermined rate. Therefore, the illuminance of the lamp La increases at a predetermined rate as shown in FIG. The dimming control unit 6 determines that the generation phase of the trigger signal is the lamp L.
When the illuminance level of "a" reaches a predetermined level of dimming level L ₀ , the generated phase is maintained and a trigger signal is output thereafter. Therefore, the illuminance of the lamp La is maintained at the dimming level L ₀ . In other words, the period from when the human body detection sensor 7 detects the human body until the lamp La is turned on and the illuminance of the human body reaches the dimming level L ₀ is the fade-on period T ₀ , which does not cause the user to feel dazzling and can be seen from the eyes. It is possible to prevent the person from being awakened by the stimulation of and not being able to sleep again. Further, the fade lighting and the dimming lighting alleviate the fear of waking up another person sleeping in the same room.

After that, when the human body detection sensor 7 no longer detects the human body and the ON detection signal is not output, the main control section 4 turns off the control signal S ₁ and turns off the power supply opening / closing section 5. When the power supply opening / closing unit 5 is turned off, the lamp La
Will turn off. By the way, in the present embodiment, the illuminance at the dimming level L ₀ is set to be higher than the determination value L _1, so that the human body detection sensor 7 outputs the light with the lamp La lit at the dimming level L _0. When the ON detection signal of is interrupted in a short time, the lamp La is turned off for a short time T _{1 as} shown in FIG. 2B, but there is a time delay until the illuminance sensor 3 newly detects an illuminance change. When the main control unit 4 receives an ON detection signal indicating an ON operation, the illuminance level taken in from the illuminance sensor 3 is the dimming level L immediately before the light is turned off.
_Since the illuminance level is ₀ , the main control unit 4 outputs the control signal S ₁ to the power source opening / closing unit 5 to make the power source opening / closing unit 5 fully conductive. Therefore, the power supplied to the lamp La is approximately rated 1
It becomes 00%, and all the lamps La are turned on.
