Description

  The present invention relates to a security lighting system.

Conventionally, a lighting device with a crime prevention function having a crime prevention function is known (see, for example, Patent Document 1).
As shown in FIG. 8, in the lighting device 100 with the crime prevention function described in Patent Document 1, a human sensor unit 101 that detects a person, a brightness sensor unit 102 that detects ambient illuminance, and a timer that measures various times Unit 103, lighting control means 104 that controls the entire appliance including these units 101 to 103, and illumination load unit 105 that outputs light.

  Therefore, when the human sensor unit 101 detects a person, the lighting control unit 104 changes the quality of light output from the illumination load unit 105 according to the ambient brightness detected by the brightness sensor unit 102. Is switched between execution and non-execution. Thereby, when the human sensor unit 101 detects a person, it is possible to switch the operation mode according to the ambient brightness, for example, whether to light normally or to perform a flashing operation for crime prevention.

Further, when the resident of the house operates the key by operating the door key as a component device within a certain time (for example, 10 seconds) after the human sensor unit 101 detects the person, The security operation can be prevented from being performed.

  However, in the lighting apparatus 100 described in Patent Document 1 described above, the mode is implemented unless a key is operated within a predetermined time, so that even a resident of the house may be threatened. It was.

  The present invention was made in order to solve the conventional problems, and an object of the present invention is to provide a security lighting system that can stop the implementation of the security mode for a certain period of time if it is a resident of the house. And

  The crime prevention lighting system of the present invention has a lighting fixture having a crime prevention function and a transmitter that emits a signal for canceling the crime prevention function, and the lighting fixture receives a signal from the transmitter and receives the crime prevention function. It has the structure which has a switch which maintains the cancellation state of the said crime prevention function for a fixed time by operating in the state canceled.

  With this configuration, when the transmitter sends a signal that is a resident of the house and approaches the entrance, the crime prevention function is canceled and does not operate, and the switch provided on the lighting fixture during this cancellation By operating, the cancel state can be continued for a certain time. Thus, the crime prevention mode can be stopped while the resident of the house opens the entrance key or performs work such as opening the key and putting the luggage.

  In the present invention, when the transmitter emits a signal that is a resident of the house and approaches the entrance or the like, the crime prevention function is canceled and does not operate, and a switch provided in the lighting fixture is canceled during the cancellation. By operating, the cancel state can be continued for a certain time. As a result, the crime prevention lighting system has an effect that the crime prevention mode can be stopped while the resident of the house opens the entrance key or performs work such as opening the key and putting the luggage. Can be provided.

Hereinafter, a crime prevention lighting system according to an embodiment of the present invention will be described with reference to the drawings.

Is a block diagram showing the configuration of the transmitter, FIG. 6 is an explanatory diagram showing the operation in the normal mode, and FIG. 7 is an explanatory diagram showing the operation in the security mode.

  In FIG. 1, a security lighting system 10 according to the present invention includes a lighting device 20 with a security function and, for example, a card key type transmitter 30 that emits a specific signal that illuminates that it is a resident.

  As shown in FIG. 1, the illuminating instrument 20 with a crime prevention function has an instrument body 20a attached to the wall 11 and the like, and a lamp body 20b attached to the instrument body 20a and having a light source 21 inside. As shown also in FIG. 2, the instrument main body 20 a includes a detection block 22, a communication unit 23 that receives a specific signal emitted by a person from the transmitter 30, and a sound output unit that can emit a sound such as an alarm sound. And a control unit 25 for controlling the above-described units 21 to 24. The appliance body 20a is provided with a crime prevention mode release switch 28 as a switch for holding the crime prevention mode canceled by a signal from the transmitter 30 for a certain period of time. When a certain time has elapsed after the crime prevention mode release switch 28 is pressed, the crime prevention mode is resumed.

The detection block 22 includes a human sensor 22a including a pyroelectric element that detects a person in a predetermined detection area, and a brightness sensor 22b including a phototransistor that detects ambient brightness. This detection block 22 is provided exposed on the lower outer surface of the instrument body, and the surface is covered with a milky white cover. This cover is formed in a lens shape and determines the detection area of the human sensor 22a.
The sound output unit 24 and the communication unit 23 are provided by cutting out the lower surface of the instrument body 20a.

  A plurality of (for example, four) setting knobs 26 are provided on the front surface of the control unit 25. As shown in FIG. 3, the lighting holding time knob 26a sets a time (lighting holding time) for turning on the light source 21 when the human sensor 22a detects a person. The brightness adjustment knob 26b adjusts the ambient brightness when the light source 21 is turned on based on the brightness detected by the brightness sensor 22b. The pick-up time knob 26c sets a pick-up time to be described later. The blinking time knob 26d sets a time (flashing start time) from when a person is detected until the light source 21 starts blinking. The setting knob 26 is provided inside the instrument body 20a and can be operated by removing a cover 27 provided in front of the setting knob 26 (see FIG. 1).

  As shown in FIGS. 4 and 5, the transmitter 30 includes an antenna 31, a battery 32, a setting unit 33, and a control unit 34, and a signal from the control unit 34 is transmitted through the antenna 31 to the instrument body 20 a. To the communication unit 23. Moreover, the setting part 33 is provided in the surface of the transmitter 30, and has the crime prevention mode switch 33a, the normal mode switch 33b, and the continuous lighting switch 33c. Using these switches 33a to 33c, a normal mode, a security mode, and a continuous lighting mode, which will be described later, can be set.

  The operation of canceling the crime prevention function using the transmitter 30 described above will be described. When the communication unit 23 of the lighting apparatus 10 receives the ID signal R from the transmitter 30 when the crime prevention mode is set, the control unit 25 collates the received ID signal R with the registered ID signal. When the received ID signal R coincides with one of the registered ID signals, the crime prevention function does not operate for a predetermined time (for example, 1 minute). Therefore, when a person other than the resident of the house enters the detection area, the crime prevention function works. However, when a resident with the transmitter 30 enters the detection area, the crime prevention mode is canceled without operating the transmitter 30.

  The communicable area of the transmitter 30 is set wider than the human detection area so that the ID signal R is received first, so that the crime prevention mode does not work for the residents of the house. Can be. Further, the transmitter 30 can emit a specific signal only by holding it without holding it over the lighting fixture 20.

  Alternatively, even when the human sensor 22a detects a person, the human sensor 22a detects the person before the resident issues a specific signal by enabling the crime prevention function to operate after a predetermined time has elapsed since the detection. However, if the communication unit 23 receives the specific signal before the predetermined time elapses, the crime prevention function can be prevented from being activated.

  As described above, the cancellation of the security mode by the ID signal R from the transmitter 30 is limited to a certain time, and returns to the security mode again after a certain time has elapsed. For this reason, in order to extend the cancellation state of the crime prevention mode, the resident pushes the crime prevention mode release switch 28 provided in the fixture body 20a of the lighting fixture 20 while the cancellation state continues. Thereby, the cancellation state of the crime prevention mode continues for a certain time.

  Next, the operation in each mode will be described.

(Normal mode)
In normal mode, it does not light in the daytime when the surroundings are bright. As shown in FIG. 6A, when the brightness sensor 22b detects that the surroundings are darker than the set brightness, the light source 21 of the lighting fixture 20 is lightly greeted with a brightness of, for example, 20%. Let In this state, as shown in FIG. 6 (B), when the person M approaches and is detected by the human sensor 22a, the light source 21 is turned on with 100% brightness, and as shown in FIG. 6 (C). When the person leaves and is no longer detected by the human sensor 22a, the light is again greeted again. Then, as shown in FIG. 6 (D), the lights are turned off when the welcome end time is reached. Thereafter, when the human sensor 22a detects a person, the light source 21 is turned on with 100% brightness to notify that the person has been detected.
By adjusting the welcome end time, the welcome lighting can be continued for a while until the morning.

(Security mode)
In the daytime when the surroundings are determined to be bright by the brightness sensor 22b, as shown in FIG. 7A, when the human sensor 22a detects a person, the light source 21 passes after a predetermined time (for example, 10 to 30 seconds). At the same time, the sound output unit 24 generates an alarm sound and intimidates the person. Thereafter, when no person is detected, the light source 21 is turned off and the alarm sound is also stopped.

  On the other hand, at night when the surroundings are determined to be dark by the brightness sensor 22b, as shown in FIG. 7C, when the brightness sensor 22b detects that the surroundings are darker than the set brightness, the light source of the luminaire 20 21 is greeted and lighted, for example, with a brightness of 20%. In this state, as shown in FIG. 7D, when a person approaches and is detected by the human sensor 22a, the light source 21 is turned on with 100% brightness. As shown in FIG. 7E, when the human sensor 22a continuously detects a person for a predetermined time, the light source 21 flashes and the sound output unit 24 emits an alarm sound. Thereafter, as shown in FIG. 7F, the alarm sound is stopped and the light source 21 is turned on at 100%.

  Then, as shown in FIG. 7 (G), when a person leaves and is not detected by the human sensor 22a, the light is greeted slightly again. Thereafter, as shown in FIG. 7 (H), the light source 21 is turned off at the end of the meeting, but when the human sensor 22a detects a person as shown in FIG. 7 (I), the light source 21 is turned off. It is lit at 100% brightness to notify that a person has been detected, and goes off when no person is detected.

  Such a crime prevention mode does not function when the crime prevention function cancel operation using the transmitter 30 is performed as described above. That is, when a person is emitting an ID signal R that is a specific signal from the transmitter 30, lighting or the like is performed according to the normal mode described above. Then, after a predetermined time has elapsed since the communication unit 23 received the specific signal, the security function returns to the operable state. Thereby, after a resident etc. disappears, it can return to a crime prevention function operation possible state reliably. If the crime prevention mode cancel switch 28 provided in the lighting fixture 20 is pressed while the crime prevention mode is cancelled, the crime prevention mode is canceled for a certain time.

(Continuous lighting mode)
When the brightness sensor 22b detects that the surrounding is darker than the predetermined brightness, the light source 21 is continuously turned on at the predetermined brightness, and the brightness sensor 22b detects that the surrounding has become bright. In the case of failure, the light source 21 is turned off.

  As described above, according to the crime prevention lighting system 10 according to the present invention described above, when the transmitter 30 emits an ID signal as a resident of the house and approaches the entrance, the crime prevention function is canceled and does not operate. By operating the crime prevention mode release switch 28 provided in the lighting fixture 20 during the cancellation, the canceled state can be continued for a certain period of time. Thus, the crime prevention mode can be stopped while the resident of the house opens the entrance key or performs work such as opening the key and putting the luggage.

The crime prevention lighting system of the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.
For example, the normal mode and the crime prevention mode shown in the above-described embodiments are examples, and various forms can be adopted.
