D, the resistor R1, the optical sensor 29 and the thyristor S are connected in parallel, and the gate of the thyristor S is connected between the resistor R1 and the optical sensor 29 via the resistor R2.

When the amount of light received by the optical sensor 29 is high during the daytime, the resistance of the optical sensor 29 is low, the thyristor S is off, and the lamp 39 is off. On the other hand, when the amount of light received by the optical sensor 29 decreases at night or the like, the resistance of the optical sensor 29 increases, the thyristor S turns on, and the lamp is activated by half-wave output.
39 is dimmed.

Next, the operation of this embodiment will be described.

First, the body of the blinker 1 is assembled into a case body.
The board 51 is inserted and arranged in the terminal 11, and the terminal 61, the lock terminal 62 and the release button 63 are inserted and arranged in the terminal housing portion 15, and the terminal 61 is connected to the power input section of the board 51.

The lamp 39 is screwed into the cylindrical socket 32 of the cover body 12, the lamp cover 34 is attached, and the cover body 12 is fitted and mounted on the front surface of the case body 11.

c is connected to the terminal board 55, and the terminal board 56 is attached to the side of the base 39a.
Are connected.

Next, in the construction, the power supply line is drawn into the wiring box 2, and the power supply line is inserted into the wire insertion hole on the back surface of the blinker body 1 and connected to the terminal 61.

A standard support 3 is attached around the large rectangular portion 23 of the blinker body 1, the blinker body 1 is inserted and housed in the wiring box 2, and the upper and lower edges of the standard support 3 are placed in the wiring box 2.
Then, a set screw (not shown) is screwed into and fixed to the screw hole of the wiring box 2 through the mounting hole 83 of the standard support 3.

The standard plate 4 is attached to the front surface of the blinker main body 1, and the large square portion 23 is fitted in the window hole 91 of the standard plate 4.

The automatic blinker thus constructed is shown in FIG.
As shown in, the large rectangular portion 23 fits into the window hole 91 of the standard plate 4, and the sensor portion 24 and the lamp portion 25 project.

Then, for example, the lamp 39 is turned off when the amount of light received by the light sensor 29 in the daytime is high, and the lamp 39 is automatically turned off when the amount of light received by the light sensor 29 decreases due to darkness during the transition from daytime to night. When the light is turned on and becomes bright at the time of transition from night to morning and the amount of light received by the optical sensor 29 is increased, the lamp 39 is automatically turned off.

In the present embodiment, the upper part of the main body is described as the ramp section 25 and the lower part is described as the sensor section 24.
The support mounting claws 42 are provided symmetrically on the center of the main body 12 so that the main body can be mounted upside down.By placing the sensor part 24 at the top of the main body, the lamp blinking illuminance can be reduced. Can be changed. This is because the amount of light received by the optical sensor 29 differs in the vertical direction due to the difference in illuminance between the floor surface and the ceiling surface.

As described above, the standard plate 4 and the standard support 3 can be used by providing the blinker main body 1 in the size applicable to the large rectangular standard of the wiring device.

Further, since the ramp portion 25 is projected from the large rectangular portion 23, it is possible to illuminate a desired direction such as the upper direction or the wall surface 73. Moreover, since the sensor part 24 is also projected and the shielding plate 28 is provided between the sensor part 24 and the lamp part 25, the optical sensor 29 is attached in an oblique direction opposite to the lamp part 25.
It is possible to prevent the sensor unit 24 from malfunctioning under the influence of the light of the lamp unit 25.

The light-receiving cover 26 is attached to the cover body 12 of the blinker main body 1.
By integrally forming the and the cylindrical socket 32, the number of parts can be reduced.

The board 51 is arranged along the direction substantially perpendicular to the front surface of the blinker main body 1 and the cylindrical socket 32 is provided, and a part of the electric parts 54 mounted on the board 51 is partially inserted into the cylindrical socket.
By arranging them in the space portions a on both sides of 32 (shown in FIG. 4), they can be efficiently arranged and stored. In addition, a terminal storage portion 15 is provided adjacent to the board 51, and the terminal storage portion 15 is provided.
By connecting the terminal 31 housed in the board to the board 51, the terminals are efficiently arranged and housed.

The light receiving window 27 provided on the light receiving cover 26 may be left open or may be closed by a light transmitting cover. Alternatively, the light-receiving cover 26 may be formed to have a thin wall without an opening so as to have a light-transmitting property.

Further, since a 100V general electric bulb is used as the lamp 39 in the lamp section 25 and the dimming lighting is performed by the half-wave output by the thyristor S, a high illuminance output can be obtained with a simple configuration without using a step-down transformer or the like. In addition, the amount of heat generated is small and the size can be reduced.
