Description

  The present invention relates to a security light installed mainly around a building or a garden.

  As outdoor lamps installed for crime prevention purposes such as at the entrance of a building or outside of a building, those that automatically turn on by detecting the approach of a human body with a human sensor are widely used (for example, Patent Document 1). etc.).

In addition, as a crime prevention facility to which a function for preventing the intrusion of a suspicious person is added, a crime prevention system in which a surveillance security camera and an imaging device are combined with a lighting fixture has been proposed (for example, Patent Documents 2 and 3). .

  An outdoor light equipped with a human sensor has a certain threatening effect against the intrusion of a suspicious person, but is not expected to have a sufficient deterrent effect against arson crimes that have been increasing in recent years. Security systems equipped with security cameras and imaging devices are also useful for investigating after the occurrence of crimes, but unless they are very conspicuous, the effects of preventing crimes are low, especially for arson crimes. There is a problem that it doesn't make much sense to operate the system after the arson has actually occurred.

  As equipment for preventing the occurrence and spread of fire, fire detection / notification equipment for detecting an alarm by detecting heat or smoke, and automatic fire extinguishing equipment such as a sprinkler are common. However, this type of equipment is mainly for public facilities and apartment buildings, and it becomes a complicated structure that constitutes a single disaster prevention system in the entire building. Not very popular. Moreover, since it is difficult to detect the occurrence of a fire outdoors where heat and smoke are likely to diffuse, it is almost defenseless against fire from outside the building.

  In recent years, human damage caused by house fires has been increasing, and in response to this, a law amending the Fire Service Act was promulgated on June 2, 2004 (enforced on June 1, 2006). As a result of this revision of the Fire Service Law, it is now mandatory to install fire alarms for all new and remodeled homes in private homes. Although this law revision is expected to increase the installation rate of fire alarms in ordinary houses and reduce the damage caused by fires occurring inside the house, Thus, effective measures have not yet been established, and further measures are desired.

  Therefore, in order to minimize damage caused by arson from outside the building as much as possible, the present invention pays attention to a crime prevention light installed around the building or a garden, and provides a new fire prevention measure using the crime prevention light. It is.

  In order to achieve the above-described object, the security light of the present invention includes a lamp body having a light source, human body detecting means for automatically detecting the approach of a human body by a human sensor and automatically turning on the light source, and an ultraviolet flame sensor. It has a fire detection means for detecting occurrence and sounding an alarm, and is configured so that it can be installed alone.

  This security light detects a suspicious person with a human sensor and automatically turns on the light source, thereby exerting a threatening effect on the suspicious person. First, when a lighter is ignited, the flame is immediately detected by an ultraviolet flame sensor and an alarm is sounded. Since an ultraviolet flame sensor that reacts with flames is used as a fire detection means, it is possible to reliably detect the occurrence of a fire even outdoors where heat and smoke are likely to diffuse. The configuration of the ultraviolet flame sensor itself may be a known conventional technique.

  In the present invention, "can be installed alone" is not a lighting facility that constitutes a part of a complex disaster prevention system, or a lighting facility that operates in cooperation with other facilities, as a single lamp, It means that it can be connected to an appropriate commercial power source (a household AC power source, a solar battery for outdoor lighting equipment, etc.). However, it is assumed that the minimum necessary ON / OFF switch is installed at an appropriate place and is electrically connected to the lamp body even if the lamp is installed alone. In this way, if the lamp can be installed alone by combining the human body detection means and flame detection means, the installation cost will be reduced, and replacement with existing outdoor lights will be easy, so an increase in the number of installations is expected. can do.

  Furthermore, the crime prevention light of the present invention is characterized in that the human body detection means and the fire detection means are each unitized and formed so as to be detachable from the lamp body. If the human body detection means and the fire detection means are unitized so that they can be attached to and detached from the lamp within a necessary range according to the installation location, the manufacturing cost and installation cost of the lamp and each unit can be reduced.

  The crime prevention light of the present invention configured as described above has an intimidating effect on the suspicious person by detecting the approach of the suspicious person with the human sensor and automatically turning on the light source, and has approached. If a suspicious person ignites a lighter or the like, the ultraviolet flame sensor immediately detects the flame and sounds an alarm, so it is highly effective in preventing the fire from being fired. Even if implemented, early fire fighting can minimize damage.

  Furthermore, the security light of the present invention is not intended to cooperate with a complicated and expensive disaster prevention system, but is configured so that the lamp, the human body detection means, and the flame detection means can be combined and installed alone. . Therefore, the degree of freedom regarding the installation location and the lamp configuration is great, the installation cost is low, the installation can be easily performed, and the replacement with the existing outdoor lamp becomes easy. Thereby, the spread in a private house etc. can be promoted and it can contribute to the crime prevention improvement in the whole area.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show a schematic configuration of a security light according to an embodiment of the present invention.

  The illustrated security light 1 is a so-called bracket-type lamp, and can be turned to the mounting seat 2 attached to the outer wall surface, the arm 3 projecting from the mounting seat 2, and the tip of the arm 3. A lamp body is configured by the light projecting unit 4 attached in this manner, and a lamp 5 serving as a light source is mounted on the light projecting unit 4. A control circuit unit (not shown) is housed inside the mounting seat unit 2, and power from a commercial power source wired on the wall surface is supplied to the control circuit unit. The control circuit unit is connected to a wall switch (not shown) installed at an appropriate location, and the lamp 5 is turned on and off by operating the wall switch.

  A human sensor unit 6 constituting a human body detecting means and a flame sensor unit 7 constituting a fire detecting means are attached to the mounting seat portion 2. Both sensor units 6 and 7 are housed in a box-shaped case unified in design, and are detachable from the mounting seat 2, and are attached to the mounting seat 2, respectively. And are electrically connected.

  The human sensor unit 6 includes a human sensor 61 that senses infrared rays emitted from the human body. As shown in FIG. 2, when a person enters the monitoring area, the human sensor unit 6 sends a detection signal to the control circuit unit. The control circuit unit turns on the lamp 5 immediately after receiving the human detection signal. When no one is present from the predetermined area, the lamp 5 is turned off after a predetermined time set by the timer has elapsed.

  In the present invention, the detailed specifications of the human sensor 61, the monitoring area setting method, and the like are not particularly limited. In addition, by combining an illuminance sensor with the human sensor unit 6, a control system is adopted in which the lamp 5 automatically turns into a half-light state when the surroundings become dim, and the lamp 5 turns into a full-light state when a person enters. May be.

  The flame sensor unit 7 includes, for example, an ultraviolet flame sensor 71 using a photovoltaic element having a strong sensitivity to ultraviolet rays in a wavelength range not included in sunlight, and detects the occurrence of flame in the monitoring area. As shown in FIG. 3, when a flame occurs in the monitoring area, the flame sensor unit 7 sends the detection signal to the control circuit unit, and the control circuit unit immediately sounds the alarm device 72. In recent years, ultraviolet flame sensors that have been put to practical use are very sensitive and can detect a small flame of lighter ignition momentarily from a position several meters away, so that the occurrence of a fire can be detected early.

  Normally, when a person enters the monitoring area, it is assumed that the human sensor 61 detects this and the lamp 5 is turned on. However, the occurrence of a flame was detected in a state where no human intrusion was detected. In this case, the lamp 5 may be set to light up simultaneously with the sounding of the alarm device 72. Further, the monitoring area of the human sensor unit 6 and the monitoring area of the flame sensor unit 7 may coincide with each other, and may slightly vary depending on the flow of people around the installation site, the state of arrangement of combustible articles, and the like. It may be shifted.

  By installing such a crime prevention light 1, it is possible to threaten a suspicious person who has entered the surveillance area with light, and if an intruding suspicious person generates a flame, immediately sound an alarm. This can prevent arson. Even if arson is executed, it is possible to minimize damage by early fire extinguishing.

  The present invention is not limited to the bracket-type lamps illustrated above, for example, a lamp of a type directly attached to the bottom of a fence or eaves, a pole-type lamp standing independently in a garden, a fence or a stairs It can also be applied to a stand-type lamp that is installed.

It is a figure which shows schematic structure of the crime prevention light which concerns on embodiment of this invention. It is a figure which shows the operating state of a security light when a person invades. It is a figure which shows the operating state of a security light when a flame generate | occur | produces.
