For this reason, when it is not in the crime prevention mode, it can be used as a lighting fixture without a sense of incongruity by using the light bulb color or white color that has been used conventionally, and in the crime prevention mode, the detected suspicious person can be threatened It is possible to provide a lighting device with a crime prevention function having an effect that a threatening effect can be increased by blinking a color or the like.

Hereinafter, a lighting apparatus with a crime prevention function according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a lighting device with a crime prevention function according to an embodiment of the present invention, FIG. 2 is an explanatory diagram showing an operation when not in the security mode, and FIG. 3 is an explanatory diagram showing an operation in the security mode.

  As shown in FIG. 1, a lighting device 10 with a crime prevention function according to the present invention is used by being attached to, for example, an entrance wall 11 or the like. The lighting fixture 10 is provided with a human sensor 13 for detecting a person and a brightness sensor 14 for detecting ambient brightness on the outside of a bottomed cylindrical fixture body 12, for example. Also, inside the fixture main body 12, three color light sources of the red LED 15R, the green LED 15G, and the blue LED 15B constituting the main light source 15 are attached in a replaceable manner, and a control unit 17 that controls the entire lighting fixture 10 is provided. Is provided.

  Note that when the crime prevention mode is turned on / off by a remote controller (not shown), a remote controller receiver 18 is provided. A cover 19 is detachably provided on the front surface of the instrument body 12.

  Therefore, by adjusting the output (brightness) of the red LED 15R, the green LED 15G, and the blue LED 15B that are the three color light sources under the control of the control unit 17, the color of the illumination emitted as the lighting fixture 10 is set to an arbitrary color. can do. Moreover, the main light source 15 can be blinked by blinking each LED15R, 15G, 15B. Alternatively, any of the LEDs 15R, 15G, and 15B can be turned on, and any of the LEDs 15R, 15G, and 15B can be blinked.

  Next, the operation in each mode will be described.

(Normal mode)
In the normal mode that is not the crime prevention mode, as shown in FIG. 2A, the brightness sensor 14 of the lighting fixture 10 detects that the surrounding is brighter than the predetermined brightness (that is, it is daytime). In the meantime, the LEDs 15R, 15G, and 15B that are the main light sources 15 are turned off. Then, as shown in FIG. 2B, when the brightness sensor 14 detects that the surrounding area is darker than the predetermined brightness, the control unit 17 turns on the LEDs 15R, 15G, and 15B with the predetermined brightness. The main light source 15 is turned on. At this time, when the color of the main light source 15 is set to the light bulb color or white, there is no uncomfortable feeling as illumination. When the turn-off time is set, as shown in FIG. 2C, the main light source 15 is turned off by turning off the LEDs 15R, 15G, and 15B after a predetermined time has elapsed.

  As shown in FIG. 2D, when the human sensor 13 detects the person M while the main light source 15 is turned off, the control unit 17 turns on the LEDs 15R, 15G, and 15B with a predetermined brightness. Then, the main light source 15 is turned on with a light bulb color or the like, and as shown in FIG. 2E, when the person M disappears, the LEDs 15R, 15G, and 15B are turned off and the main light source 15 is turned off. Even if the turn-off time is not set, as shown in FIG. 2 (F), when the brightness sensor 14 detects that it is brighter than the predetermined brightness and has become in the morning, the main light source 15 is turned off.

(Security mode)
The state before the crime prevention mode is set is the same as the normal mode described above. That is, as shown in FIG. 3A, when the brightness sensor 14 detects that the surroundings are bright daytime, the main light source 15 is turned off. As shown in FIG. 3B, when the brightness sensor detects that the brightness becomes darker than the predetermined brightness, the main light source 15 is turned on with a light bulb color or the like.

  On the other hand, for example, when the crime prevention mode is set by a remote controller (not shown), the main light source 15 is turned off at the set time as shown in FIG. As shown in FIG. 3D, when the human sensor 13 detects the person M, the control unit 17 turns on the LEDs 15R, 15G, and 15B with a light bulb color or the like, and the human sensor 13 keeps the human sensor 13 for a certain period of time. When the person M is detected as described above, the control unit 17 turns on the LEDs 15R, 15G, and 15B at a predetermined ratio, thereby blinking with light of any color, and threatens the person M.

  When the person M disappears, the main light source 15 is turned off as shown in FIG. Thereafter, when the human sensor 13 detects a person again, the above-described FIG. 3D is repeated. When the brightness sensor 14 detects that the brightness is higher than the predetermined brightness (that is, in the morning), the main light source 15 is turned off thereafter, as shown in FIG.

  As described above, according to the lighting device 10 with a crime prevention function according to the present invention described above, the three color light sources of the red LED 15R, the green LED 15G, and the blue LED 15B are provided as the main light source 15, and therefore light of any color can be emitted. it can. For this reason, when it is not a crime prevention mode, it can be used as the lighting fixture 10 without a sense of incongruity by making it the light bulb color and white used conventionally, and can detect the suspicious person M detected at the crime prevention mode. The threatening effect can be further increased by blinking such a color.

In addition, the lighting fixture with a crime prevention function of this invention is not limited to embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.
For example, in the above-described embodiment, the description has been given of the case where the security mode is operated after the surroundings are darker than the predetermined brightness and the normal lighting is performed for the set time. It may be set to operate even in the daytime brighter than the brightness. In this case, the combination of the red LED 15R, the green LED 15G, and the blue LED 15B emits light of a color that clearly shows blinking or the like even in the daytime, thereby enhancing the threatening effect.
