Abstract

PROBLEM TO BE SOLVED: To provide an automatic photoelectric type ON-OFF switch which makes the lighting illuminance easy to set in accordance with the installation environment and the application. SOLUTION: This is equipped with set switches 4a to 4c and this is operational from outside and equipped with an input part 4 to switch the lighting illuminance or input the light-out time. When the set switch 4a is press-operated, operation signals are input from the input part 4 into the control part 1 and the control part 1 turns to a lighting iluminance set mode. When the lighting illuminance set signals are input from the input part 4 into the control part 1 by the set switch 4b press-operated in the lighting illuminance set mode, the control section 1 memorizes the detection level of the peripheral illuminance input from the illuminance detection part 3 at that point of time. Accordingly, by the set switch 46 being press-operated with the operation mode in the lighting illuminance set mode, the lighting illuminance can be easily set in accordance with the installation environment and application.

[0002]

2. Description of the Related Art Conventionally, when the ambient illuminance is detected and the illumination illuminance falls below a predetermined lighting illuminance, a power supply path from an external power supply (commercial power supply) to the illumination load is closed to illuminate the illumination load. When the turn-off time is reached, a photoelectric automatic blinker for stopping the supply of power from the external power supply to the lighting load and turning off the lighting load has been provided (Japanese Utility Model Laid-Open No. 62-121839, Japanese Unexamined Patent Publication No.

When the present embodiment constructed as described above is mounted on a wall, the waterproof packing 40 provided with an opening 41 corresponding to the terminal block 12 is led out from the wall with the waterproof packing 40 interposed between the terminal block 12 and the wall. A screw insertion hole (not shown) provided substantially at the center of both ends in the longitudinal direction of the body 20 with respect to the mounting frame 50 disposed on the wall surface by inserting a power supply line and a load line through the opening window 51.

It is fixed to the wall by screwing it into a screw hole 52 provided substantially at the center of both ends in the longitudinal direction.

When the present embodiment configured as described above is used, the operation mode is first set by the setting switch 4a. That is, when the setting switch 4a is pressed, an operation signal is input from the input unit 4 to the control unit 1, and the control unit 1 enters the lighting illuminance setting mode. At this time, the control unit 1 controls the light emitting diodes LD1, LD1 corresponding to the setting switches 4a, 4b.
The LD 2 is turned on to indicate that the mode is the lighting illuminance setting mode. In this lighting illuminance setting mode, when the setting switch 4b is pressed and a lighting illuminance setting signal is input from the input unit 4 to the control unit 1, the control unit 1 transmits the ambient illuminance input from the illuminance detecting unit 3 at that time. Is stored in the built-in memory as the lighting illuminance. At this time, the stored lighting illuminance may be displayed on the indicators 8a and 8b. Therefore, by pressing the setting switch 4b while the operation mode is set to the lighting illuminance setting mode, the lighting illuminance can be easily set in accordance with the installation environment and use.

When the setting switch 4c is pressed in the lighting illuminance setting mode, a lighting illuminance switching signal is input from the input unit 4 to the control unit 1. When a lighting illuminance switching signal is input, the control unit 1 alternately sets a plurality of predetermined lighting illuminances (for example, 10 to 40 lx and 100 to 350 lx). At this time, the control unit 1 turns on the light emitting diodes LD1 and LD3 corresponding to the setting switches 4a and 4c. Also in this case, the set lighting illuminance (or a number corresponding to each lighting illuminance) may be displayed on the indicators 8a and 8b. Therefore, the lighting illuminance can be set more easily according to the installation environment and use than setting the detection level of the surrounding illuminance to the lighting illuminance as described above. The control unit 1 automatically stores the illuminance, which is about five times the set illuminance, as the unlit illuminance in the built-in memory.

Next, when the setting switch 4a is pressed again, an operation signal is input from the input unit 4 to the control unit 1, and the control unit 1 is set to the light-off time setting mode. At this time, the control unit 1
Is a light emitting diode L corresponding to the setting switches 4a to 4c.
D1 to LD3 are turned on to indicate that the mode is the turning-off time setting mode. Here, the current times (hours and minutes) counted by the normal timer unit 5 are displayed for 24 hours on the indicators 8a and 8b. However, in the light-off time setting mode, the light-off time set (light-off time is not set). "-" For setting
In this extinguishing time setting mode, the extinguishing time (hour and minute) is set using the setting switches 4b and 4c. That is, every time the setting switch 4b is pressed, "0" is displayed on the display 8a. To "23" are sequentially displayed. Every time the setting switch 4c is pressed, "00" to "23" are displayed on the display 8b.
A number 59 "is sequentially displayed. Then, the setting switch 4a is pressed and operated from the input unit 4 to the control unit 1 while the turning-off time to be set is displayed on the indicators 8a and 8b.
When the operation signal is input to the control unit 1, the control unit 1 sets the time as the light-off time in the timer unit 5, switches the operation mode to the normal mode, and displays the current time on the indicators 8a and 8b. Therefore, conventionally, when the setting switch is operated, the time is set as the light-off time, and the desired light-off time cannot be set immediately at the time of construction, and moreover, it is set. Although the light-off time could not be confirmed, in this embodiment, as described above, any time can be set to the light-off time by using the setting switches 4b and 4c in the light-off time setting mode. Is easy to use, and the turning-off time set by the indicators 8a and 8b can be confirmed, thereby facilitating the setting operation.

When the setting of the lighting illuminance and the turning-off time is completed, the setting switch 4a is pressed to set the control unit 1 in the normal mode. At this time, the control unit 1 controls the light emitting diodes LD1 to LD
D3 is turned off to indicate that the mode is the normal mode. In the normal mode, the control unit 1 outputs a control signal to the relay drive unit 6 when the detection level of the illuminance detection unit 3 falls below the lighting illuminance stored in the built-in memory. The relay contact r is closed. When the relay contact r is closed, the external power supply AC → the power supply terminal T1 → the relay contact r → the load terminal T2 → the lighting load L → the common terminal T3.
→ The power supply path of the external power supply AC is formed, and the illumination load L is turned on. Then, the timer unit 5 outputs a timer signal to the control unit 1 when the current time matches the turn-off time. When the timer signal is input, the control unit 1 outputs a control signal to the relay drive unit 6 and causes the relay drive unit 6 to open the relay contact r of the relay 2. When the relay contact r is opened, the power supply path is not formed, and the power supply from the external power supply AC to the lighting load L is stopped, and the lighting load L is turned off.

By the way, the external power supply AC
When the power failure is detected, the control unit 1, the timer unit 5, and the like receive the power supply from the backup power supply 11 and hold the current time count and the data of the set lighting illuminance and the set off time.
