Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the first embodiment. In this figure, the lighting device 1 is installed on the ceiling of a car or a room. The light emitting means 11, the light emission control means 12 for controlling the light emission amount and the light emission time of the light emitting means 11, and the light emitting means 11 emit light. There are several patterns, such as a light emission pattern that functions as a normal room lamp when the door of a car or room opens when not on alert, or a light emission pattern that functions as a strobe light when the door opens during warning The light emission pattern storage means 13 for setting and storing the light emission pattern, and the light emission pattern selection means 14 for selecting a predetermined light emission pattern from a plurality of light emission patterns stored in the light emission pattern storage means 13. It consists of and.

  Further, the door opening switch 2 that detects whether or not the door of the car or the room is open and transmits a predetermined signal to the light emission pattern selection means 14 when the door is opened, and the level of warning, that is, whether or not the warning is in progress. And a warning mode setting means 3 for detecting whether or not and issuing a signal at the time of warning.

FIG. 2 is a block diagram showing a detailed configuration when the lighting device 1 shown in FIG. 1 has a room lamp function and a strobe light function for suspicious person threatening.
In this figure, the same or corresponding parts as in FIG.
The light emitting means 11 uses a bright high-intensity LED (light emitting diode) with the highest brightness to realize the strobe light function, and the light emission control means 12 is used as a shift register 12A and a signal from the shift register 12A. The shift register 12A, the light emission pattern storage means 13, and the light emission pattern selection means 14 are constituted by the microcomputer 15, and the light emission pattern read from the light emission pattern storage means 13 is shifted to the shift register. 12A is sequentially output.

  The light emitting means 11 may use a light bulb or other light emitting means instead of the LED, and the shift register 12A may be realized by software, a peripheral device with a built-in microcomputer, or the like. The transistor 12B can also be configured using an FET or other amplification means. Furthermore, the warning mode setting means 3 is connected to a door lock system of a car or a room, for example, and issues a warning mode signal in response to locking of the door.

  In addition, a lamp switch 20 is provided that can switch the lighting state of the lamp between three states of ON, OFF, and AUTO, and a signal corresponding to the lighting state is transmitted to the light emission pattern selection means 14 and an object inside or outside the car or the room. And a radio wave sensor 21 for transmitting the distance information to the light emission pattern selecting means 14, and detecting the vibration of the window glass or the vibration of the car body and transmitting the corresponding signal to the light emission pattern selecting means 14. In addition, a vibration sensor 22 constituting a detection device for a suspicious person is provided together with the radio wave sensor 21 and the like. The radio wave sensor 21 and the vibration sensor 22 may be provided in the lighting device 1 as shown in FIG. 2, but may be provided outside as necessary. Another sensor such as an infrared sensor may be used.

Next, the light emission pattern selection operation according to this embodiment will be described with reference to the flowchart shown in FIG.
First, in step S1, it is determined whether or not a warning is being made based on a signal from the warning mode setting means 3. If it is not alerting, it will progress to step S2, if it is alerting, it will progress to step S4. In step S2, the state of the lamp switch 20 is determined. If AUTO, the process proceeds to step S3. If ON, the process proceeds to step S6. If OFF, the process proceeds to step S5.

  In step S3, a signal from the door opening switch 2 is received to determine whether or not the door is open. If the door is open, the process proceeds to step S6, the light emission pattern 1 is selected, and for example, the room lamp is lit to continuously emit light with low luminance. If the door is not open, the process proceeds to step S5, and a pattern without light emission is selected. The pattern without light emission is turned off, and this pattern is selected during standby.

If the alert is in step S1, whether or not there is a suspicious person is detected based on the distance information from the radio wave sensor 21 and the presence / absence of vibration information from the vibration sensor 22 in step S4.
If a suspicious person is detected here, the process proceeds to step S7, the light emission pattern 2 is selected, and the flashlight blinks with high brightness to threaten the suspicious person and prevent crimes.
If no suspicious person is detected, the light emission pattern 3 is selected in step S8, and the LED blinks to indicate that it is on alert. If the flashing light is emitted, the suspicious person knows that he / she is on the alert, which has the effect of preventing crime.

FIG. 4 specifically shows the blinking state of the LED in each light emission pattern stored in the light emission pattern storage means 13, where the vertical axis indicates the light emission luminance and the horizontal axis indicates the time.
In the figure, (a) shows the light emission pattern 1 shown in FIG. 3, which is a pattern for realizing the room lamp function, and light emission pulses having a predetermined luminance are continued at regular time intervals.
The brightness can be arbitrarily set by PWM (Pulse Width Modulation).
For example, when setting to 1/10 of the maximum brightness of the light emitting means, ON time / OFF time = 1/10.

  FIG. 3B shows the light emission pattern 2 shown in FIG. 3, which is a pattern for realizing the strobe light function, and is set to turn on for 50 ms at the maximum brightness and then turn off for 1 second. (C) shows the light emission pattern 3, which is a blinking light emission pattern, and is set to blink at low luminance. (D) is a pattern without light emission, which is a pattern for turning off the light, and is always set to OFF.

The first embodiment is configured as described above, and the function of the room lamp is the light emission pattern 1 that always lights with low brightness. For example, the light emission pattern that gradually becomes dark when the door is closed, etc. Other light emission patterns may be set.
Further, the function of the strobe light is the light emission pattern 2 for threatening when a suspicious person is detected, but the number of times of light emission may be repeated a plurality of times as necessary.
Further, the flashing light emission pattern 3 which is a flashing light emission pattern indicates a warning, but when the warning mode is changed by a keyless entry or the like, it may be used to confirm whether or not the operation is surely performed. Good. Moreover, although this illuminating device shall be installed in a ceiling, the same effect can be expected even if it installs in another place, such as a step. In that case, it can be used not as a room lamp but as a foot lamp or a map lamp.
Since LEDs are used as the light emitting means, various light emission patterns can be easily realized, and the reliability is high and the structure can be made small.

  With such a configuration, it is possible to provide a security function at a low cost by using one kind of light emitting means without deteriorating the design of the room lamp or the map lamp.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a block diagram showing a configuration of the second embodiment. In this figure, the same or corresponding parts as in FIG. The difference from FIG. 1 is that the illuminating device 1 is provided with an image pickup means 16 for receiving a signal from the light emission pattern selection means 14 and photographing the inside of the vehicle or the room.
In this embodiment, when a suspicious person is detected, the light emission pattern 2 that emits strobe light is selected, and at the same time, the shutter of the image pickup means 16 is released to take a clear image in the vehicle or the room. Can be realized.

  The light emitting means 11 uses a visible light high-intensity LED or the like in order to realize a room lamp function, but may also include an infrared light LED at the same time. If the infrared LED is turned on at the same time as taking a picture, it is possible to take a picture without being noticed by a suspicious person even in the dark, and a night vision camera function can be realized.

FIG. 6 specifically shows a configuration including both the visible light LED 11 </ b> A and the infrared light LED 11 </ b> B as the light emitting means 11.
In this figure, reference numerals 12B and 12C denote transistors, which amplify the light emission pattern signal output from the shift register 12A. Reference numeral 16 denotes a camera as imaging means.
The shift register 12A is the same as that of FIG. 2 in that it sequentially outputs the light emission patterns read from the light emission pattern storage means 13, but for the visible light LED 11A, the infrared light LED 11B, and the camera 16. 2 differs from that of FIG. 2 in that a plurality of signals are output simultaneously. Similarly, each of the light emission patterns 21 to 25 stored in the light emission pattern storage unit 13 stores a plurality of signals, as will be described later. Other configurations are the same as those in FIG.

  Next, the operation of the second embodiment will be described. By the light emission pattern selection means 14, the warning mode from the warning mode setting means 3, the setting state from the lamp switch 20, the presence or absence of a suspicious person obtained from the radio wave sensor 21 and the vibration sensor 22, and the door opening from the door opening switch 2. As in the first embodiment, the light emission pattern corresponding to the situation is selected from the state.

  Here, the plurality of light emission patterns stored in the light emission pattern storage means 13 will be described in more detail with reference to FIG. (A) shows a pattern for realizing the room lamp function as the light emission pattern 21 and includes patterns for the visible light LED 11A, the infrared light LED 11B, and the shutter of the camera 16, but only the visible light LED 11A is included. It always emits light with low brightness. (B) shows a light emission pattern 22 for realizing a flash photographing function, which is set so that the visible light LED 11A emits light with high luminance and at the same time the shutter of the camera 16 is operated.

  (C) is a light emission pattern 23, which is a pattern for realizing a night vision camera function, and is set to operate the shutter of the camera 16 at the same time as the infrared LED 11B emits light. (D) is a light emission pattern 24, which is a pattern for realizing the functions of both the night vision camera and the room lamp. The infrared light LED 11B is continuously lit at a low luminance while the visible light LED 11A is continuously lit. And the shutter operation of the camera 16 are set to be performed simultaneously. (E) is a light emission pattern 25, which indicates a light-off pattern, and is set so that none of the LEDs emit light and the shutter of the camera 16 does not operate.

FIG. 8 is a flowchart for explaining the pattern selection function executed by the CPU in the microcomputer 15.
In step S11, it is determined based on a signal from the alert mode setting means 3 whether or not alert is being performed. If it is during alerting, it will progress to step S12, and if not alerting, it will progress to light emission pattern selection table S14. In step S12, if a suspicious person is detected from the distance information from the radio wave sensor 21 and the vibration information from the vibration sensor 22, the process proceeds to step S13, and if not detected, the process proceeds to the light emission pattern selection table S14. In step S13, the light emission pattern 22 is selected and flash photography is performed.

In the light emission pattern selection table S14, any one of the light emission patterns 21, 23, 24, and 25 is selected from the setting state of the lamp switch 20 and the door state signal of the door open switch 2.
In other words, when the door is closed, the function of turning off the light emission pattern 25 is selected when the lamp switch 20 is OFF or AUTO, and the room lamp function of the light emission pattern 21 is selected when the lamp switch 20 is ON. When the door is open, the night vision camera function of the light emission pattern 23 is selected when the lamp switch 20 is OFF, and the night vision camera + room lamp function of the light emission pattern 24 is selected when AUTO or ON. The

  With the above configuration and operation, in addition to the normal room lamp function, when a suspicious person is detected during monitoring, a suspicious person can be threatened by flash photography and a clear image can be taken. Even if the door is opened, it is possible to check the situation when an abnormality is found by photographing with the night vision camera function when the door is opened.
