Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an entrance lighting system equipped with an outside light and a white light.

(Prior Art) In an entrance lighting system, a manual switch is provided on a wall or the like inside the entrance, and the outside entrance light and the inside entrance light are turned on and off by turning on and off the manual switch. However, operating such a manual switch is cumbersome, and power is often wasted due to forgetting to turn off the switch.

On the other hand, a system has been developed that uses a human sensor such as an infrared sensor to turn on a lighting fixture when a person is present within the detection area, and automatically turns off the light when the person is no longer present.

(Problem to be solved by the invention) It is possible to apply the above automatically controlled lighting system to the entrance. When controlled independently, there are the following drawbacks.

For example, when a visitor arrives near the entrance, the outside lights are first turned on based on a human body detection signal from a human sensor placed outside the entrance. However, the white lights remain off until visitors enter the entrance, giving a cold impression to visitors. Furthermore, when a visitor leaves, the white light is turned on first, but the outside light remains off until the visitor leaves the front door, causing anxiety to the visitor.

(Means for solving the problems) The present invention has been made to solve the above problems,
The gist of this is that an outside entrance light, an inside entrance light, a first human body detection means having a detection area outside the entrance, a second human body detection means having a detection area inside the entrance, and a first human body detection means having a detection area inside the entrance. The entrance lighting system is characterized by comprising a control means for lighting both an outside entrance light and an inside entrance light when a human body detection signal is received from any of the second human body detection means.

(Function) When a person enters the detection area of the first human body detection means outside the entrance, the control means turns on the outside light at the entrance and also turns on the inside light at the entrance. Similarly, when a person enters the detection area of the second human body detection means in the entrance, the control means turns on the light inside the entrance and also turns on the light outside the entrance.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

As shown in FIG. 2, an outdoor light 10 is installed outside the entrance, and a white light 20 is installed inside the entrance. The entrance light 10 is supported by a housing 11 attached to the outer surface of the wall via a bracket 11a. The entrance light 20 is
It is supported by the lower surface of a housing 21 attached to the ceiling.

A human sensor 12 (first human body detection means) and an illuminance sensor 13 are installed on the lower side of the housing 11 outside the entrance. The detection areas of these sensors 12 and 13 are approximately equal and are indicated by A in the figure.

A human sensor 22 (second human body detection means) and an illuminance sensor 23 are installed on the lower surface of one side of the housing 21 in the entrance. The detection areas of these sensors 22 and 23 are approximately equal and are indicated by B in the figure.

The human sensors 12 and 22 are equipped with a filter and a thermopile that selectively pass infrared rays, and have a detection area A.
Alternatively, convert the infrared rays from B into voltage, compare this voltage with a reference level using a comparator, and when it exceeds the reference level, it is determined that a person has entered the detection area, and an H level human body detection signal is output. do.

The illuminance sensors 13 and 23 receive visible light from the detection area A or B, convert it into a voltage, compare this voltage with a reference level using a comparator, and when it is below the reference level, it is determined that it is dark enough to require illumination. It is determined that there is a low illuminance detection signal and outputs an H level low illuminance detection signal.

Inside the housing 11 is a first
A second control unit 25 for controlling the white light 20 is housed in the housing 21 .

=4- As shown in FIG.
2 and an AND circuit 30 connected to the output side of the illuminance sensor 13. The set terminal S of the seventeenth lip 70 tube 31 is connected to the output side of the AND circuit 30. Further, the output side of the human sensor 12 is connected to the reset terminal R of the seventeenth lip 70 knob 31 via the inverter 32.

The output terminal Q of the 17th lip 70 tube 31 has an OR
A dimming control circuit 35 is connected via a circuit 33 and a timer 34. In this dimming control circuit 35, the output terminal Q
When an H level signal is received from the outside entrance light 10, it is turned on at high brightness, and when it receives an L level signal, it is turned on at low brightness. In this dimming control circuit 35, the brightness level when the light is turned on at low brightness can be adjusted by operating the volume. Note that the brightness level when lighting at high brightness may also be adjusted.

On the other hand, the output side of the illuminance sensor 13 is connected to the set terminal S of the twenty-seventh lip 70 knob 36.

Further, the output side of the illuminance sensor 13 and the output side of the timer 34 are connected to a reset terminal R of a twenty-seventh wamp-flop 36 via a NOR circuit 37. The output terminal Q of the twenty-seventh lip 70 tube 36 is connected to an on/off control circuit 38 consisting of a relay circuit or the like.

The exterior entrance light 10, the dimming control circuit 35, and the on/off control circuit 38 are connected in series via a power supply line AC.

Since the second control section 25 has the same configuration as the first control section 15, the same reference numerals are given to the constituent parts in the figure, and detailed explanation thereof will be omitted.

1st. The second control units 15 and 25 are configured to send and receive control signals to and from each other via the transmission means 40.

The transmission means 40 includes a transmitting circuit 41 and a receiving circuit 42 installed in the housing 11 outside the entrance, and a transmitting circuit 43 and a receiving circuit 44 installed in the housing 21 inside the entrance.

The transmitting circuit 41 outside the entrance emits weak radio waves based on the pulse signal from the AND circuit 30 of the first control section 15, which is received by the receiving circuit 44 inside the entrance and converted into a pulse signal again to perform the second control. The signal is sent to the OR circuit 33 of the section 25. Moreover, on the contrary, the transmitting circuit 43 inside the entrance is
A weak radio wave is emitted based on the pulse signal from the AND circuit 30 of the second control section 25, received by the reception circuit 44 outside the entrance, converted into a pulse signal again, and then ORed by the first control section 15.
It is sent to circuit 33.

The transmitting means 40 and the first. Second control unit 15.25
The control means 45 is constituted by.

In the above-mentioned configuration, automatic control of the entrance light 10 will be explained first. When the illuminance of the detection area A is low and the surrounding area is dark enough to require illumination, the illuminance sensor 13 outputs a low illuminance detection signal of H level. This low illuminance detection signal becomes a set signal for the 27th lip 70 knob 36, so the output from the output terminal Q of the 27th lip 70 knob 36 is high.
level, and the on/off control circuit 38 turns on. As a result, the power supply circuit consisting of the power supply line AC is closed.
The entrance light 10 is turned on.

The lighting state of the entrance outdoor light 10 is selected by the dimming control circuit 35 as either high brightness or low brightness. That is, even if the illuminance sensor 13 outputs an H-level low-illuminance detection signal, if there is no person in the detection area A, the human sensor 12 will not output an H-level human body detection signal, so the AND circuit 30 No set signal is output from the 17th lip-flop 31, and its Q output remains at the L level. Therefore, the dimming control circuit 35 puts the entrance outdoor light 10 into a low-intensity lighting state based on this L-level signal.

By the way, the detection area A of the illuminance sensor 13 is the entrance outdoor light 10.
Since the illumination area overlaps with the illumination area of The detection output from 13 remains at H level.

As shown above, if the surrounding area remains dark, a person can
Since the human sensor 12 also outputs an H level human body detection signal, the AND circuit 30 outputs an H level set signal to the 17th lip 70 knob 31. As a result, the output terminal Q of the 17th lip 70 tube 31
The output becomes H level, and the dimming control circuit 35 turns the entrance outdoor light 10 into a high-intensity lighting state based on this H level signal.

By the way, the detection area A of the illuminance sensor 13 is the entrance outdoor light 10.
Since the illumination area A overlaps with the illumination area A, the moment the outside entrance light 10 is turned on, the illuminance of this detection area A becomes high and the detection output from the illuminance sensor 13 becomes L level. However, in the seventeenth lip 70 tube 31, the output from the output terminal Q remains at the H level unless a reset signal, which will be described later, is input.

Furthermore, since the output from the output terminal Q of the 17th lip 70 tube 31 remains at H level, the output from the timer 34 also remains at H level, and therefore, the NOR circuit 37
In this case, even if an L level signal is received from the illuminance sensor 13, the reset signal is not output to the 27th flip-flop 36, and the output from the output terminal Q of the 27th flip-flop 36 remains at the H level.

As a result, the on/off control circuit 38 remains in the on state, and the dimming control circuit 35 maintains the entrance outdoor light 10 in a high brightness lighting state.

In the above-mentioned high-brightness lighting state, when there is no person in the detection area A, the output of the human sensor 12 becomes L level, which is inverted by the inverter 32 to become an H level reset signal, which resets the 17th lip-flop 31. Input to terminal R. As a result, the output of the 17th lip 70 tube 31 becomes L level. However, this L level signal is delayed by the timer 34 and reaches the dimming control circuit 35, so even after the person is gone from the detection area A, the entrance outdoor light 10
continues to maintain the high brightness lighting state for the time set by the timer 34, and then switches to the low brightness lighting state. Therefore, it is possible to prevent inconveniences such as switching to low brightness as soon as the light exits the detection area A, giving people a sense of discomfort and anxiety.

The output from the timer 34 becomes L level and the entrance light 10 is turned on.
When the surrounding area becomes bright while the lamp is in a low brightness lighting state, the NOR circuit 37 receives L level signals from both the illuminance sensor 13 and the timer 34, so the second
A reset signal is output to the 7 lip-flop 36. As a result, the output of the $27 flip-flop 36 becomes L level, the on/off control circuit 38 is turned off, the power supply circuit is opened, and the entrance light 10 is turned off.

The entrance light 20 also has a human sensor 22 and an illuminance sensor 23.
The second control section 25 similarly controls the detection signal from the second control section 25.

The exterior entrance light 10 and the interior entrance light 20 are interlocked.

More specifically, when a person reaches the detection area A in a dark environment, the output of the AND circuit 30 becomes an H level pulse as described above. As mentioned above, this pulse signal is sent to the 17th lip 70 knob 31 and becomes a control signal to turn on the outside entrance light 10, and is also sent to the transmitting circuit 41, where it is converted into a weak radio wave and is received by the entrance. circuit 44
Here, the signal is converted to an H level pulse again and inputted to the timer 34 via the OR circuit 33 of the second control section 25. After receiving this pulse, the timer 34 outputs an H level signal to the dimming control circuit 35 for a set period of time, so the entrance light 20 remains in a high-intensity lighting state for only this period.

Thus, for example, when a visitor arrives outside the front door,
Since not only the outside entrance light 10 but also the inside entrance light 20 are lit with high brightness, visitors will not be given a cold impression or feel uneasy.

On the other hand, when a person reaches the entrance from the hallway and is about to go out, the entrance light 10 is turned on under the control of the second control section 25, and the pulse from the AND circuit 30 of the second control section 25 is turned on. It is sent to the transmitting circuit 43 inside the entrance and converted into a weak radio wave, which is received by the receiving circuit 42 outside the entrance and converted into a pulse, and this pulse is sent to the OR circuit 3 of the first control section 25.
3, the outside entrance light 10 is also turned on.

This invention is not limited to the above-mentioned embodiments, and various embodiments are possible. For example, the lighting system of the present invention may also be controlled by a manual switch.

Further, when a person enters the detection area of the human body detection means outside the entrance, the outside entrance light may be turned on immediately, and the inside entrance light may be turned on with a delay of several seconds.

Further, when the outside entrance light is turned on at high brightness, the inside entrance light may be turned on at low brightness from the off state.

1st. The second control section may be configured by a microcomputer.

The transmission means may perform signal transmission using infrared rays. Alternatively, it may be simply composed of electric wires for signal transmission.

(Effects of the Invention) As explained above, in this invention, by linking the outside entrance light and the inside entrance light, it is possible to give a good impression to visitors and the like.
