Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic lighting control system for a house.

[0002]

2. Description of the Related Art An automatic lighting / extinguishing device for a house uses a human body detection sensor. When a person enters the detection area of the human body detection sensor, the human body detection sensor generates a human body detection signal and tries to enter the person. The controller of the illuminating lamp in the room or space receives the human body detection signal to turn on the illuminating lamp, and the timer is set. When this timer times out, the controller turns off the illumination lamp.

However, in the case where the above-mentioned illumination light is, for example, a stairway light, it is dangerous if the surroundings become dark in the evening. Therefore, the stairway light should be turned on halfway from the evening to the next morning. Have control. In this case, an illuminance sensor that outputs when the ambient illuminance is less than or equal to the set illuminance is provided, and while the illuminance sensor is outputting, the stairway lights are lit halfway and the human body detection sensor outputs a human body detection signal during this half-lighting. When it occurs, all lights are turned on for a predetermined time. When the ambient illuminance is equal to or higher than the set illuminance, the staircase light is not turned on even if the human body detection sensor generates a human body detection signal.

When this system is adopted as a front light, etc., when a person comes to the front of the front door, the front light is suddenly turned on all the way from the half-lighted state, so there is a slight crime prevention effect.

[0005]

When a system for lighting the stairs half-time during the night is adopted as the stairway light, there is an advantage that it is not necessary to go up and down the stairs by feeling, but almost all stairs after going to bed are not available. Even when not in use, the staircase lights are half-lit, which is uneconomical.

Further, since the illuminance sensor continues to output until the ambient illuminance reaches the set illuminance, even when the illumination becomes a brightness where it becomes unnecessary, the semi-lighting state continues and full lighting occurs.

Of course, when a switch is provided and the brightness becomes a level where illumination is not required, the switch output with the switch turned on may be used to disable half lighting or full lighting.
When you need lighting, you have to operate this switch, and if you forget to operate it, even if the surroundings become dark,
The lighting does not come on.

According to the present invention, not only can the crime prevention function more effective than conventional ones be exhibited by utilizing the above-mentioned system, but also waste of electricity due to continuation of the half-lighted state can be prevented without inconvenience. It is an object of the present invention to provide an automatic lighting control device for a house capable of performing the above.

It is an object to provide an automatic lighting control device for a house.

[0010]

In order to achieve the above object, the present invention comprises a human body detection sensor, an illuminance sensor that outputs when ambient illuminance is below a set illuminance, and a dimmer.
The dimming device puts an illumination lamp into a dimming state when the output of the illuminance sensor is input, and when the human body detection sensor generates a human body detection signal, all the illumination lamps are provided on condition that the illuminance sensor is outputting. An automatic lighting control device for a house that is switched to a lighting state has a mode switch, and when the mode switch is turned on, the input of the output of the illuminance sensor to the light control device is blocked and the light control is performed. The device, when the human body detection sensor generates a human body detection signal,
The illumination lamp is lit in a crime prevention condition on condition that the mode switch is turned on.

[0011]

In the present invention, when the mode switch is turned on,
Since the output of the illuminance sensor to the dimming device is blocked, it is possible to prevent continuation of the dimming state such as half-lighting of the illumination lamp, if necessary.

Further, since the crime prevention light is turned on when a person comes in after the mode switch is turned on at night or the like, the crime prevention function can be enhanced as compared with the conventional case.

[0013]

First Embodiment One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 is a pyroelectric sensor having an entrance as a detection area, 2 is an amplifier circuit, 3 is a level judging device (comparator), and 1 to 3 are human body detecting sensors A.
Reference numeral 4 is a timer having a set time T. Reference numeral 5 is an illuminance detector, 6 is a level determiner (comparator), 7A and 7B are one-shot multi, 8 is a flip-flop, and 4 to 8 constitute an illuminance sensor B. 9A, 9B and 9C are gate circuits, 1
Reference numeral 0 is a light control device for a front light, and 11 is a front light.

Further, 12 is a mode switch, 13 is a one-shot multi, and 14 is a flip-flop.

In this configuration, when it is evening and the surroundings are dark, the output of the level determiner 6 changes from "L" to "H", and the one-shot multi 7A generates a pulse at the rising edge of the flip-flop 8. Is set and the timer 4 is enabled. At this time, since the set output of the flip-flop 14 is "L", the gate circuit 9A
Outputs a signal of level "H". This signal is a "half-lighting instruction", and the light control device 10 that has received this signal turns on the front light 11 by half.

In this state, when a person stands at the front door and the human body detection sensor A outputs a human body detection signal, the timer 4 outputs and at the same time starts counting. The output of the timer 4 is the "all lighting command" and is input to the gate circuit 9B.

The gate circuit 9B outputs an "H" signal when it receives the output of the timer 4 when the set output of the flip-flop 14 is "L" (when the mode switch 12 is not held). Upon receiving this signal, the light control device fully turns on the entrance lamp 11 for a predetermined time T.

When the mode switch 12 is turned on, the one-shot multi 13 generates a pulse at the rising edge of the switch output, and the flip-flop 14 is set. As a result, the set output of the flip-flop 14 changes from "L" to "H", so that the "half-lighting instruction" output from the gate circuit 9A disappears.

When the surroundings become bright in the morning, the output of the level determiner 6 changes from "H" to "L", and the flip-flops 8 and 14 are reset in synchronization with the fall. Therefore, neither the "half-lighting command" nor the "full-lighting command" is generated.

The gate circuit 9B outputs a signal of "H" when receiving the output of the timer 4 when the set output of the flip-flop 14 is "H". This "H" signal is an "alarm command", and the light control device that has received this signal turns on the front light 11 for crime prevention lighting (for example, flashing lighting) for a certain time T.

As described above, in this embodiment, the half-lighted state can be eliminated by turning on the mode switch 12, so the mode switch 12 is turned off before going to bed.
If you operate N, the waste of electricity by half lighting will disappear until the next morning, and during that time, if a person stands at the front door, all the front lights 11 will automatically light up, so it is inconvenient. Absent.

Before going to bed, turn the mode switch 12 to O.
If N is operated, when a person stands at the front door, the front light 11 turns on the crime prevention light, so that the person who comes to the front door is fully threatened,
A crime prevention effect can be obtained.

In the above embodiment, the entrance light has been described as an example, but the present invention can be applied to other illumination lights such as a stairway light to obtain the same effect.

[0025]

As described above, the present invention is provided with a switch for stopping the dimming such as half-lighting by the light control device as necessary, and all lighting is possible, which causes inconvenience. However, for example, it is possible to eliminate useless power consumption while sleeping, and since the crime prevention light is turned on when a person invades while all lights are off, the crime prevention function can be enhanced as compared with the conventional case.
