Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illuminating device having the features of both an ordinary illuminating device and a crime prevention and intimidating illuminating device by applying a human sensor and a timer.

[0002]

2. Description of the Related Art Recently, security has been worsening in Japan as well, and in particular, a special tool called picking is used to unlock the door of the entrance door of a house and the number of burglary damage that illegally enters the house increases dramatically. is doing. Under such circumstances, many lighting fixtures having a crime prevention effect have been devised in the field of residential lighting fixtures.

First, as Conventional Example 1, a most common sensor-equipped residential lighting fixture will be described.

As shown in the explanatory views of FIGS. 10, 11, and 12, the human sensor section 10, the brightness sensor section 11, and the timer section 12
Is a sensor lighting fixture 15 having a lighting control means 13
When a human detection signal is input from the human sensor unit 10 and the brightness sensor unit 11 outputs a dark signal at that time, the lighting load (light source unit 14) is turned on. Then, while the human sensor unit 10 is detecting a person, the lighting state is maintained and the light is turned off after a predetermined time set in advance after the detection signal of the human sensor unit 10 is not input.

In this case, since the surroundings are dark at night, the lighting load 14 is turned on when the thief comes near the lighting equipment 15, so it is considered that there is a temporary threatening effect and crime prevention effect. However, this lighting device 15 is not intended for crime prevention, but for the purpose of improving energy saving and convenience by automatically turning on / off the light by the human sensor unit 10. Even if an ordinary person comes to the front door, a thief or other malicious person may Even if the person who holds it comes to the front door, the lighting will be exactly the same, so in that sense, this lighting fixture has the problem that the crime prevention effect is still insufficient. Further, depending on the setting state of the brightness sensor unit 11, there remains a serious problem that the lighting load 14 does not light up even if a person is detected in the bright daytime.

[0006] From the above, a lighting apparatus having a higher crime prevention effect has been devised. It has been commercialized by Matsushita Electric Works (Matsushita Electric Works part number LW86710T: product name "Hitoukun").

As Conventional Example 2, an explanatory view of this luminaire is shown in FIGS. This lighting fixture 16 has a human sensor unit 10, a brightness sensor unit 11, and a timer unit 12 mounted on the lighting control means 13. In order to enhance the crime prevention effect as compared with general sensor lighting fixtures, the brightness sensor unit 11 has If a detection signal is input from the human sensor unit 10 while outputting a dark signal, the lighting load 14 has a flash function of repeatedly blinking in a short period instead of lighting. However, in this case, since the crime prevention function is prioritized, if the detection signal of the human sensor unit 10 is input, the flashing always starts immediately, so even if the detected person is a thief,
Even the resident of the house will blink. Moreover, even if the resident of the house just passes through the front door, the person sensor unit 10 detects the person and the person blinks instead of lighting, which poses a serious problem that it cannot be used as a normal lighting fixture.

For this reason, even if the human sensor detects a person, the quality of the light output from the lighting load section is not changed immediately (hereinafter, referred to as "reporting"). An alarm device has been devised to issue a crime prevention signal for the first time when a human sensor detection signal is input a predetermined number of times or more within a predetermined time after first detecting a person (JP-A-9-
178548).

The prior art example 3 disclosed in the publication has a human sensor and a brightness sensor, and the control signal output section includes a lighting output section for a lighting load and a crime prevention output section for a crime prevention system.
It has a system control signal output section. In this conventional example, when a detection signal of a human sensor is input, a lighting load control signal is output from the lighting output unit. Then, if a human sensor detection signal is input a predetermined number of times or more within a predetermined time, or if a human sensor detection signal is input for a predetermined time, a crime prevention system control signal is output from the crime prevention output unit after the predetermined time. Is output. However, this device is originally intended for large-scale systems such as office buildings, and for the threatening action for crime prevention and alarm transmission, a crime prevention system that performs a predetermined operation after receiving a crime prevention signal output is connected separately. There is a need to. In addition, even with this system, if there is a detection input from a human sensor for a certain period of time or more, a warning signal will always be issued and a crime prevention signal will be output, so not only people targeted for crime prevention such as burglary thieves but also general people If the user stays within the detection range of the human sensor for a time, the system will start the crime prevention operation.

From the above, in the residential field, a lighting device which is completed with a lighting device and has a simple structure and which can provide the effects of a normal lighting device and can also provide a certain effect for crime prevention, It is desired to devise a lighting device that can easily switch between a normal operation mode and a crime prevention operation mode.

[0011]

The residential luminaire having a crime prevention function, which has been commercialized in the past, is a luminaire with a human sensor as in the conventional example 1, and the human sensor simply illuminates a person. In many cases, if it is detected, it lights up for a predetermined time. In this case, the function as a lighting fixture is fulfilled, but there is a problem that the effect in terms of crime prevention is not so great.

On the other hand, as a luminaire having a higher crime prevention effect, there is a similar luminaire with a human sensor, in which the illuminating load flickers (flashes) from the time when the human sensor detects a person as in the conventional example 2. Exists. However, in this luminaire, when the human sensor detects a person, the blinking always starts from that moment, so the crime prevention effect is sufficient, but the function cannot be satisfied as a general usage of the luminaire. For example, if a resident of the house where this luminaire is installed passes by near this luminaire, it will start flashing (flash) as if it were a crime victim such as a burglar thief. , I feel very uncomfortable and cannot say that it functions as a general lighting fixture.

Further, in the one having the control signal output section of two systems, that is, the illumination output section and the crime prevention output section as in the conventional example 3,
It is necessary to connect a security system separately, and it is used as a device for office buildings and large-scale systems, and is not suitable for general housing.

Therefore, an object of the present invention is to provide an illuminating device which has a function as an ordinary illuminating device and can obtain a high effect as a crime prevention illuminating device.

[0015]

In order to solve the above-mentioned problems, a lighting device according to claim 1 of the present invention is a human sensor section for detecting a person, a lighting load section for outputting light, and the human sensor section. And a lighting control means for controlling the entire apparatus including the above, and if the human sensor section detects a person, the lighting control means can implement a crime prevention function of changing the quality of light output from the lighting load section. In the lighting device described above, the lighting control means performs switching of whether or not to perform the crime prevention function according to the brightness in the vicinity of the lighting device.

In this way, the lighting control means switches whether or not to implement the crime prevention function in accordance with the brightness in the vicinity of the lighting device. Therefore, when the human sensor section detects it, for example, it normally lights. It is possible to change the operation mode such as whether to perform the crime prevention flashing operation according to the ambient brightness. That is, when the detection signal of the human sensor unit is input, it is possible to easily switch between the crime prevention operation mode in which a crime prevention / intimidation effect is generated and the normal operation mode as a simple sensor lighting fixture, and thus a simple configuration is possible. Nevertheless, there is provided a lighting device that has the highest crime prevention effect under each of the circumstances and that also sufficiently functions as a normal lighting fixture.

An illumination device according to a second aspect of the present invention comprises a human sensor section for detecting a person, an illumination load section for outputting light, and a lighting control means for controlling the entire apparatus including the human sensor section. A lighting device capable of performing a crime prevention function of changing the quality of light output from the lighting load unit by the lighting control unit when the human sensor unit detects a person, wherein the lighting control unit is the crime prevention unit. The function is switched on or off according to the time zone.

In this way, the lighting control means switches whether or not to perform the crime prevention function according to the time of day. Therefore, when the human sensor detects, for example, the normal lighting or the crime prevention function is performed. Switching of the operation mode, such as whether to perform the blinking operation, can be made variable according to the time zone. That is, when a detection signal from the human sensor unit is input, a crime prevention operation mode in which a crime prevention / intimidation effect is generated,
Since it is possible to easily switch the normal operation mode as a mere sensor lighting fixture, despite the simple configuration, it is the most effective crime prevention under each situation, and it is a normal lighting fixture. There is provided a lighting device that sufficiently fulfills the function of.

An illumination device according to a third aspect of the present invention includes a person sensor section for detecting a person, an illumination load section for outputting light, and a lighting control means for controlling the entire apparatus including the person sensor section. A lighting device capable of performing a crime prevention function of changing the quality of light output from the lighting load unit by the lighting control unit when the human sensor unit detects a person, wherein the lighting control unit is the crime prevention unit. The function is switched on or off according to the operation of the external device.

In this way, the lighting control means switches whether or not the crime prevention function is carried out according to the operation of the external device. Therefore, when the human sensor section detects, for example, whether or not the lighting is normally carried out, Switching of operation modes, such as whether or not a crime prevention flashing operation is performed, can be made variable according to the operation of an external device. That is, when the detection signal of the human sensor unit is input, it is possible to easily switch between the crime prevention operation mode which produces a crime prevention / intimidation effect and the normal operation mode as a simple sensor lighting fixture.
Despite the simple structure, there is provided a lighting device which has the highest crime prevention effect under each of the circumstances and also sufficiently functions as a normal lighting fixture.

A lighting device according to a fourth aspect is the lighting device according to the third aspect, wherein the external device is a key of a door of a house. In this way, since the external device is the door key of the house, the operation mode can be switched depending on the opening / closing operation of the door key. For this reason, it is possible to switch the optimal operation mode when going out, at home, operating a key, etc., without being particularly conscious of it.
