形成されるのである。 Now, when it gets dark, the impedance of the photoelectric conversion element 5 increases and turns on the transistor Tr1 . As a result, a constant current flows through the resistor R1 to the light emitting element 8a of the photocoupler 8, and the light receiving element 8b
impedance decreases and triggers the thyristor 3. At this time, the trigger level of the thyristor 3 can be set by controlling the current flowing through the light emitting element 8a to the resistor R1 , and the load 2 is lit at a constant illuminance. That is, the photoelectric conversion element 5 and the transistor
A first level setting section is formed by Tr 1 and resistor R 1 . Next, when the operation switch 7 is turned on, the switching element S is turned on, and the base current of the transistor Tr 2 flows through the capacitor C 1 and the resistor R 2 , and the transistor Tr 2 is turned on. As a result, current flows through the resistor R 3 to the light emitting element 8a of the photocoupler 8, the impedance of the light receiving element 8b further decreases, the trigger level of the thyristor 3 changes, and the load 2 reaches its maximum illuminance.
When capacitor C 1 finishes charging, transistor Tr 2
is turned off, the current flowing through the light emitting element 8a also returns to its previous state, and the illuminance of the load 2 also returns to its original state. Furthermore, the holding current no longer flows in the switching element S, so that it is turned off, and the charge in the capacitor C1 is discharged through the resistors R4 , R5 and the diode D1 .
That is, the transistor Tr 2 and the resistor R 3 form a second level setting section. Also,
Since the series circuit of transistor Tr 1 and resistor R 1 and the series circuit of transistor Tr 2 and resistor R 3 are connected in parallel with each other, the setting state of the second level setting section is the setting state of the first level setting section. This parallel circuit forms a control order setting section.

ることもできる。 In this way, when the surroundings become dark, the load 2 lights up dimly, and when the operation switch 7 is turned on, it becomes bright for a certain period of time, then returns to the original state, and when the surroundings become bright, it can be turned off automatically. Lighting is necessary for nighttime security, but it is turned on with less power consumption to save resources, and can be turned on at maximum brightness only when people are passing by. Furthermore, the illuminance when the lamp is always on can be changed by changing the resistor R1 to a variable resistor, and can also be adjusted depending on the installation location.

When the light is turned on and the operating switch 7 is turned on, the thyristor 3 is turned on in all cycles via the full-wave rectifier D, and the load 2 is turned on in full-wave mode to change the illuminance, which simplifies the circuit configuration. can.
