  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an external view showing an entrance lamp to which a lighting device according to an embodiment of the present invention is applied.

  In FIG. 1, the entrance lamp includes a main body chassis 1, a front cover 2 attached to the main body chassis 1, two light sources 3 and 4 disposed in the main body chassis 1, and the light sources 3 and 4. A drive circuit mounting wiring board 5, a human sensor 6, and a sunset sensor 7 are provided.

  The main body chassis 1 is formed into a box shape with a front wall open, for example, of resin or metal material, and is attached to a wall near the entrance by a fixing means such as a screw. In the main body chassis 1, predetermined socket portions (not shown) corresponding to the light sources 3 and 4 are arranged.

  The front cover 2 has translucency and is attached to the opening of the main body chassis 1 and is formed in a square shape corresponding to the shape of the main body chassis 1 with translucent milky white resin, for example. ing. The front cover 2 covers the two light sources 3 and 4 from the front of both the light sources 3 and 4 in a shared state.

  Of the two light sources 3 and 4, one light source 3 emits light for normal illumination in the normal mode, and a fluorescent lamp is used, for example. Of course, incandescent bulbs, halogen lamps, xenon lamps, light emitting diodes (LEDs), and the like can also be used.

  The other light source 4 is a light source that emits red light for intimidation in a warning mode, and for example, a red light emitting LED is used. The number of LEDs is not particular, but it is preferable to use a plurality of LEDs together. Of course, the threatening light source 4 is not limited to an LED, and any light source can be used as long as it is a light emitting body that emits red light.

  The human sensor 6 detects a person who enters a certain area near the light sources 3 and 4, and an infrared sensor or the like is used, for example.

  The sunset sensor 7 detects that the brightness of the surroundings has fallen below a certain level as the sun goes down. For example, an illuminance sensor is used.

  FIG. 2 is a block diagram showing an electrical configuration of the entrance lamp.

  In FIG. 2, the entrance lamp includes a light source driving circuit 8 mounted on the wiring board 5 in addition to the sensors 6 and 7.

  The light source drive circuit 8 includes, for example, a control unit 21, a light control unit 22, a blinking transmission unit 23, a switching unit 24, and a timer unit 25.

  The control unit 21 receives the detection signals from the human sensor 6 and the sunset sensor 7 and drives and controls the light sources 3 and 4 according to the normal time mode and the warning mode. Specifically, when the sunset sensor 7 detects sunset, in the normal time mode, the normal illumination light source 3 is driven to turn on, and after a certain time has elapsed since sunset, the normal time mode is switched to the warning mode. In this state, when the human sensor 6 detects a suspicious person who has entered a certain area, the threatening light source 4 is controlled to blink.

  For example, when the sunset sensor 7 detects that the brightness of the surroundings has fallen below a certain level after sunset, the light control unit 22 turns on the light source 3 for normal illumination in the normal mode, for example, 50 When the human sensor 6 detects the intrusion of the person in that state, the dimming is performed at 100%, for example, so that the main light is emitted. .

  The blinking transmission unit 23 causes the threatening light source 4 to blink in the alert mode when the human sensor 6 detects the intrusion of a person.

  The switching unit 24 automatically switches between a normal mode and a warning mode according to the control of the control unit 21.

  The timer unit 25 measures the lapse of a fixed time after the sunset sensor 7 detects sunset. For example, the timer unit 25 operates the switching of the switching unit 24 when the time elapses 6 hours.

  Next, the operation of the illumination device having the above configuration will be described.

  When the sun goes down and the ambient brightness is below a certain level, the sunset sensor 7 is activated. When the sunset sensor 7 detects sunset, the control unit 21 in the light source driving circuit 8 controls the switching unit 24 to switch to the normal mode, and the dimming unit 22 reduces the normal illumination light source 3 to 50% or less. The light is adjusted to enter a standby light emission state.

  In this normal mode standby light emitting state, when a person enters a certain area, the human sensor 6 detects the intruder, and accordingly, the light source 3 for normal illumination is dimmed 100% by the dimmer 22. Will be lit.

  Specifically, especially in the time zone that does not require vigilance from evening to midnight, as a normal time mode, the normal illumination light source 3 is lit with a dimming degree of 50% or less and the human sensor 6 When a person who has entered the area is detected, the normal illumination light source 3 is switched to 100% dimming. Thereby, the front of the entrance is brightly illuminated with the normal illumination light source 3 in the regular lighting state, and it is possible to satisfactorily cope with the visit of a guest or the return of a householder.

  It should be noted that, for example, if a guest leaves from a certain area until a certain time, for example, 6 hours elapses after the sunset, the human sensor 6 detects the guest and accordingly the light source for normal illumination. 3 is switched to 50% or less dimming by the dimmer 22 and returns to the standby light emission state.

  With the sunset detection of the sunset sensor 7, the timer unit 25 starts a time measuring operation, and the time is up when the predetermined time has elapsed. Since the time falls into the night time zone that requires caution, the control unit 21 switches from the normal mode to the caution mode via the switching unit 24.

  In this alert mode, when a person enters a certain area, the human sensor 6 detects it, and accordingly, the threat light source 4 is driven to flash and emit light.

  When a person illegally enters the certain area, the intimidating light source 4 is turned on suddenly from the lighting state in the normal mode, and the intimidating person can be intimidated by flashing light emission. In other words, this flashing light emission has a high effect of destabilizing the mental state, and has a crime prevention effect such that it cannot be committed by a normal mind.

  In particular, since the threatening light source 4 blinks red and emits light, a threatening effect against illegal intruders is effectively exhibited.

  By the way, with respect to the intimidating effect of red light emission, there is a configuration in which the red hood is illuminated through the red hood, for example, like a police car light. It can be predicted, and even if the light source flashes, it is inferior to the threat.

  On the other hand, the threatening light source 4 is always covered with the same front cover 2 as the normal illumination light source 3 as in this example, so its presence cannot be detected in advance, and illegal intrusion can be prevented from the situation. If detected, the red light flashes instantly, so that the threatening effect is high and reliable crime prevention is guaranteed.

  The blinking light emission of the threatening light source 4 may be in a constant state, but it is preferable to change the blinking. For example, if it is repeated with a blinking pattern of 0% → 100% → 0% → 100%..., The threatening effect is enhanced by increasing the anxiety toward the suspicious person. The blinking switching is preferably set to about 0.25 seconds, for example.

  Since the intimidating light source 4 is covered with the same front cover 2 as the normal illumination light source 3, it does not give an uncomfortable feeling during the daytime, and protects both the light sources 3 and 4.

  Moreover, although the control part 21 controlled the switching part 24 to automatically switch between the normal mode and the warning mode in the above embodiment, the switching part 24 is a manual type, and sunset detection is performed. It is also possible to manually switch from the normal mode to the alert mode when a certain time has passed.

  In the above embodiment, the human sensor 6 and the sunset sensor 7 are both provided in the illumination main body provided with the normal illumination light source 3 and the threatening light source 4. Without being limited thereto, as shown in FIG. 3, the human sensor 6 and the sunset sensor 7 are separate from the illumination main body 40 including the normal illumination light source 3 and the threatening light source 4. It is also possible to adopt the configuration provided in the above.
