Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic delay extinguishing circuit that turns off a lighting load after a certain period of time, and its purpose is to turn on the lighting load 100% by operating a switch, and turn it off after a certain period of time. There is provided an automatic delay turn-off circuit that turns off the light or turns on the light at an arbitrary lighting rate depending on the light state.

Embodiments of the present invention will be described in detail below with reference to the drawings. In Figure 1
o92 diagram is shown. In the figure, 111 is an AC power supply, and this power supply (

1 is connected in parallel to the series circuit of the sub-light 5 (3) and the switch 14). Figure 112 shows a specific circuit diagram, - the optical device ill is the aforementioned tri-hook TRt, the tri-ac DIA that provides a trigger pulse to the gate of the triac TRs, and the 52-diac DIAK volume that provides a breakover voltage at an arbitrary phase. It consists of VR+ etc. The automatic light-off switch circuit 111) is

It is composed of a triac TR3, etc. Automatic light-off switch circuit (output end 171 tl of 61) #-j
, which is connected in parallel to the series circuit of the switch +41 and the sub-optical device I11, also serves as an input terminal for driving the internal circuit. In the N@ri neon rush, the automatic light-off switch circuit (61 indicates that power is applied without operating. Also, switch 1-
A terminal 1101 ill is provided in parallel with 1, and this terminal 11

Now, under normal conditions, switch 14+ is on.
[Then, by adjusting the volume vR1 of light -1l+, set the lighting load 12) to the desired dimming level.
You can adjust the brightness. Next, the switch 141 is opened, and when the automatic light-off switch circuit (switch III of 61 is pressed to turn it on), the contact closes and current flows through the current transformation transformer CT.The current on the secondary side of the current transformation transformer CT The bridge rectifier gDBtK flows and is rectified, and the capacitor Cs is charged via the resistor Rm and the diode D1.The charge #i charged in the capacitor Cm starts to be discharged by the value of the volume vR1.Then, the transistor T

T is turned on, and the switch pre-clevel current of the thyristor T set by the resistor Ri flows to the gate of the thyristor T.

Then, when thyristor T is turned on, bridge rectifier DBI
The current flowing through keeps the triac TRm on,
When the discharge ends, no current flows to the gate of the triac TRs, turning off the triac TRs. Here, when the triac TRs is turned on, the automatic light-off switch circuit (61 output terminal 1?1ill will be short-circuited, and the power supply 1111 lighting load 1!l and output terminal 17) (8+
A closed loop is formed, and as shown in FIG. 3, the lighting load 1!1l-t100\ is lit at time t1.

After the capacitor CI has finished discharging, the trier lift T
When R1 is turned off, the output terminal 17111%1 is opened and the lighting load turns off at time t3. Time T1 is the delay time of the automatic full moon switch circuit (6). Also, the switch 141 is closed. Then, when V is set to operate the dimmer 131, as shown in Figure 3, from time 1 onwards, the dimmer lights one lighting load at the dimming level set in '41. You can perform this operation in another location or

A diode to ensure the reverse bias of the diode/dancer C1, a resistor Rm and a gate current limiter 1 for the thyristor T, a resistor 4 for limiting the anode current of the thyristor T, and a resistor Rs to limit the anode current of the thyristor T. This is the bias of the thyristor T and the diode Ds.

After a certain period of time has elapsed, it can be used as a night light by turning on the light using a dimmer, for example, and can be used as a night light by turning off the first switch during the day. Since it is possible to add an additional switch in parallel to the switch, you can add an additional switch to another location by simply connecting it in parallel with the second switch, and the effect is that it can operate in the same way as the second switch. play.
