【Example】

 An embodiment of the present invention will be described with reference to FIGS. In this embodiment, a light receiving element that detects the ambient illuminance, a control unit that controls the supply of power to the lighting load according to the ambient illuminance detected by the light receiving element to control the operation of the lighting load, and a circuit unit. The integrated circuit unit consists of a power supply that supplies power to the unit.

In this embodiment, the phototransistor PT is used as the light receiving element, and the triac TR is used as the switching element of the control unit. That is, ON / OFF or conduction angle of the triac TR is controlled according to the ambient illuminance detected by the phototransistor PT, and lighting control, lighting control, or dimming control of the lighting load is performed. The circuit components of the control unit including the phototransistor PT and the triac TR, and the circuit components of the power supply unit are mounted on the printed board 1. Here, since the TRIAC TR generates a large amount of heat, the radiating plate 3 is used to radiate heat.

A plug blade 2 for power input and load control output is integrally attached to the printed circuit board 1. Here, there are three blades 2, and the negative electrode line of the power source and the load control output are commonly connected to one blade 2. Further, the printed circuit board 1 is provided with a connector CN for connecting a timer (not shown), and by connecting the timer, the operation of the lighting load can be controlled even according to the set time by the timer. It

The case 4 for accommodating the circuit block is made of synthetic resin, and is formed in a box shape having an open upper surface. The lower ends of both side surfaces are curved so as to have a rounded lower end. . The position corresponding to the light-receiving surface of the phototransistor PT on the lower surface of the case 4 is made to have a light-transmitting property to serve as a daylighting window portion 4a. Further, an insertion window 4b for inserting the timer side connector is formed at a position corresponding to the connector CN.

A door that can be opened and closed is attached to the insertion window 4b. The door is composed of a vinyl chloride thin plate-like closing plate 6 and a slide knob 5 for driving the closing plate 6. In this door, the slide knobs 5 are formed by inserting the slide pieces 5a formed on both ends into the slide grooves 4c formed on both sides of the daylighting window 4b, and by inserting the slide pieces 5a into the insertion holes 6a of the closing plate 6 to be welded. It is formed. The closing plate 6 has an opening 6b formed at one end thereof and having the same size as the insertion window 4b.

To open and close the door, hold the knob portion 5b of the slide knob 5 and slide the slide knob 5 to align the position of the opening 6b with the position of the insertion window 6, as shown in FIG. 2 (b). , The insertion window 4b is opened. On the contrary, if the positions of the insertion window 6 and the opening 6b are completely displaced, the insertion window 4b is closed as shown in FIG. The side surface of the case 4 is curved as described above so that the flexible closing plate 6 can slide along the inner surface of the case 4 as shown in FIG. .

A thick holder 7 having an insertion hole 7 a through which the blade 2 is inserted is attached to the upper opening of the case 4. A protrusion 7b is formed on the side surface of the holder 7, and the holder 7 is fixed to the case 4 by press-fitting the protrusion 7b into the press-fitting hole 4d of the case 4. Further, as shown in FIG. 2A, the locking claw 2a is locked to the holder 7 with the locking claw 2a formed on the base of the blade 2 and the holder 7 attached to the upper opening of the case 4. Thus, it functions to firmly fix the holder 7 and to prevent the holder 7 from coming off.

If the circuit unit is unitized as in this embodiment and can be connected to the pedestal by a so-called plug-in method, the circuit unit can be commonly used regardless of the intended use. In other words, if a blade receiving part that receives the blade 2 of the circuit unit and is connected to the load control line and the power supply line is provided on the side of the pedestal that is attached to the outer wall of the house, telephone pole, or pole, the pedestal The circuit unit can be used in common by only changing the structure on the side. Therefore, it is possible to eliminate the waste and trouble of completely redesigning according to the intended use. Moreover, since a timer can be connected, it can be used in combination with a timer.

Moreover, by making the circuit unit detachable in this way, in the case of a circuit abnormality, it can be dealt with by exchanging the circuit unit, and the maintenance becomes easy. Also, if several types of circuit units are created in a characteristic manner, there is an advantage that the user's request can be met by simply replacing the circuit units.
