As can be seen from the perspective view of FIG. 2, the light source 20 has a translucent cover 20 a that covers the plurality of LEDs 1 to 4. A reflective cover 21 is provided along the edge of the translucent cover 20 a so as to surround the light source 20. A collar 21 a is provided at the tip of the reflection cover 21. A changeover switch 9 is provided in the collar portion 21a.

  In the first embodiment, the image sensor 7 is attached to a place different from the lighting fixture 10, and therefore the image sensor 7 is not shown in FIG. The image sensor 7 is installed at a position where the type of the irradiation object 6 stored in a product case or the like can be detected and determined. For example, the image sensor 7 may be attached to any place of the product case, or may be attached to another structure outside the product case. Various known imaging elements can be used for the image sensor 7. Although there is no particular limitation on the structure, the image sensor 7 includes, for example, a light receiving element, a signal processing unit, and a transmission unit. The image sensor 7 causes the light receiving element to image the irradiation object 6 on the light receiving surface of the sensor, the signal processing unit performs signal processing to photoelectrically convert the brightness and darkness of the image into a charge amount, and detects the detection information of the irradiation object 6 The signal including the signal is transmitted to the microcomputer 51 (see FIG. 4 described later) of the lighting device 5 by the transmission unit. By using the image sensor 7, it is possible to specifically and accurately detect what the irradiation object 6 is irradiated by the lighting fixture 10.

  The luminaire 10 comprises connectors 11, 12, 13. An electric wire for supplying power to the lighting device 5 is connected to the connector 11. An electric wire for inputting a signal from the image sensor 7 to the lighting device 5 is connected to the connector 12.

Further, an output signal from the microcomputer 51 on the internal substrate of the lighting device 5 is transmitted to the management terminal 8 via the connector 13.

  A signal from the image sensor 7 may be transmitted to the lighting device 5 by wireless communication, or a signal from the lighting device 5 may be transmitted to the management terminal 8 by wireless communication. Thus, when exchanging by wireless communication, the connector 12 and the connector 13 may be omitted. Furthermore, the changeover switch 9 may also be installed at a position different from the lighting fixture 10 as a wireless communication switch. The microcomputer 51 may realize the switch switching operation by the wireless terminal as the switch 9 performing wireless communication with the lighting device 5.

  FIG. 3 is an overview diagram illustrating an example of the selector switch according to the first embodiment of the present invention. The changeover switch 9 according to the present embodiment is, for example, a five-step slide type switch for designating one of "pan", "meat", "vegetable", "fresh fish" and "automatic". Depending on whether the slide position of the changeover switch 9 is "pan", "meat", "vegetable", or "fresh fish", the lighting state of the LED 1 to LED 4 is a plurality of predetermined LED lighting / non-lighting Switch between combination patterns. On the other hand, when “automatic” is set, automatic lighting control using the image sensor 7 is performed.

  FIG. 4 is a circuit diagram according to the first embodiment of the present invention. The lighting device 5 includes a rectifier circuit DB, a DC-DC converter, a smoothing circuit, switching elements Q1 to Q4, and a microcomputer 51. The rectifier circuit DB is composed of a diode bridge that rectifies an input commercial power supply (AC voltage) AC. The DC-DC converter is connected to the rectifier circuit DB and steps down the pulsating voltage output from the rectifier circuit DB. The DC-DC converter is not particularly limited because various known circuit methods can be adopted. For example, FIG. 4 shows a flyback converter as an isolated DC-DC converter including the transformer TR. As shown in FIG. 4, a transformer TR having a primary winding and a secondary winding, a switching element Q0 connected in series to the primary winding, a diode having an anode connected to one end of the secondary winding, and a switching element Q0 It includes a control IC to control. Since the circuit configuration and operation of the flyback converter are known, detailed description thereof is omitted. The smoothing circuit is a smoothing capacitor connected in parallel to the DC-DC converter, and specifically, one end thereof is connected to the cathode of the diode and the other end is connected to the other end of the secondary winding of the transformer TR It is a smoothing capacitor. The voltage output from the DC-DC converter can be smoothed by the smoothing circuit, and direct-current power can be supplied to the connected LEDs 1 to 4. The switching elements Q1 to Q4 are connected in parallel with the LEDs 1 to LED4, respectively. That is, the switching element Q1 can be connected in parallel to the anode end and the cathode end of the LED 1 to switch between conduction and interruption at both ends, and the switching element Q2 can be connected in parallel to the anode end and the cathode end of the LED 2 to Switching between conduction and interruption is possible, switching element Q3 is connected in parallel to the anode end and cathode end of LED 3, and switching between conduction and interruption at both ends is possible, and switching element Q4 is the anode end and cathode end of LED 4 It is possible to switch between conduction and interruption at both ends by connecting in parallel. The cathode end of LED1 and the anode end of LED2 are connected, and the cathode end of LED3 and the anode end of LED4 are connected. When the number of LEDs is further increased, the number of switching elements connected in parallel to the added LEDs may be increased and controlled by the microcomputer 51. Here, by appropriately turning off the switching elements Q1 to Q4 desired to be turned off by the OFF signal from the microcomputer 51, the LED1 to LED4 corresponding to the turned off switching elements Q1 to Q4 discharge the electric charge from the smoothing circuit to be lit. be able to. At this time, for the switching elements Q1 to Q4 selectively turned on by the on signal from the microcomputer 51, a current flows between the drain and the source, and thus the LEDs 1 to LED4 corresponding to the turned on switching elements Q1 to Q4 are not lighted Can be

  The microcomputer 51 receives a signal from the image sensor 7 and a signal from the changeover switch 9. The microcomputer 51 is separately connected to the control signals of the switching elements Q1 to Q4, and can individually control on / off of the switching elements Q1 to Q4. The microcomputer 51 can also perform control of the control IC and signal transmission to the management terminal 8.

  The microcomputer 51 includes a storage unit such as a RAM and a ROM, an arithmetic unit that performs arithmetic processing, an input / output port for performing data input / output, and the like. In the storage unit, as shown in Table 2 to be described later, information in which appropriate illuminance and color temperature are determined corresponding to each of a plurality of types of irradiation objects 6 (for example, bread, meat, vegetables, fresh fish, etc.) is stored in advance. Keep it.

  Table 1 below is a table summarizing the color temperatures of the emission colors of the LEDs 1 to 4. Table 2 below shows an example of a table stored in advance in the storage unit of the microcomputer 51.

  If the type of object is different, the appropriate illuminance and color temperature of the light emitted by the light source 20 will be different. "Lighting control content" is preset. Specifically, the lighting control content includes the on / off switching pattern of each of the switching elements Q1 to Q4 and the output current value to be generated for flowing to the light source 20. In Table 2, it is set as an example how many times the DC-DC converter should generate the output current with respect to the basic set current value IF. The microcomputer 51 controls the control IC and the switching element as shown in Table 2 to change the color temperature and illuminance of the light emitted from the light source 20.

  In the table shown in Table 2 above, the LEDs connected in parallel to the switching elements that are “OFF” among the switching elements Q1 to Q4 are lit. On the other hand, the LEDs connected in parallel to the switching elements that are “ON” among the switching elements Q1 to Q4 do not light up. For example, in the table shown in Table 2 above, in the case of “pan”, the switching elements Q1 and Q3 are turned off, so that the LEDs 1 and 3 are turned on. In this case, an average color temperature of LED1 and LED3, that is, a color temperature of (3000k + 3500k) / 2 = 3250k can be realized.

(Automatic lighting control using image sensor 7)
The case of automatically controlling the irradiation light using the image sensor 7 will be described. When the signal transmitted from the image sensor 7 is received, the microcomputer 51 first acquires detection information of the irradiation target 6 from the received signal (step S100). The storage unit of the microcomputer 51 stores “object information” in which the correspondence between the output signal of the image sensor 7 and the irradiation object 6 is predetermined. In step S100, the microcomputer 51 compares and collates the reception signal from the image sensor 7 with the above object information, and specifies whether the object detected by the image sensor 7 is bread, meat, fruit or fresh fish. Be done.

  Next, the microcomputer 51 reads lighting control information from a table such as Table 2 stored in the storage unit of the microcomputer 51 based on the detection information in step S100 (step S102). For example, when the object is "pan", the microcomputer 51 refers to the table in Table 2 to read the lighting control content in which the switching elements Q1 and Q3 are turned off and the switching elements Q2 and Q4 are turned on. For the output current, the set value "IF x 1" is read. Thereby, the lighting control content required in order to implement | achieve the illumination intensity and color temperature which adapt to this irradiation target object 6 is acquirable. According to the acquired lighting control content, the LEDs 1 and LED3 corresponding to the switching elements Q1 and Q3 turned off are turned on. Since the switching elements Q2 and Q4 are turned on and current flows between the source and drain of each of the switching elements Q2 and Q4, no current flows in the LEDs 2 and LED 4 corresponding to the switching elements Q2 and Q4. As a result, LED2 and LED4 Does not light.

  Next, the microcomputer 51 operates the lighting device 5 according to the lighting control content and the output current setting value read in step S102 (step S104). That is, for example, when the irradiation target 6 is "pan", the microcomputer 51 turns off the switching elements Q1 and Q3 and turns on the switching elements Q2 and Q4. On the other hand, for example, when the irradiation object 6 is “meat”, the microcomputer 51 turns off the switching elements Q2 and Q3 connected in parallel with the LED2 and LED3, respectively, and switches the switching elements Q1 and Q3 connected in parallel with the LED1 and LED4, respectively. Turn on Q4. Therefore, when the irradiation object 6 is “meat”, the LED 2 and the LED 3 are lit, and the LED 1 and the LED 4 are not lit.

  In the first embodiment, as a preferable mode, the microcomputer 51 gives a control signal to the control IC of the DC-DC converter in accordance with the value set in the right end column of Table 2, It also performs output adjustment. Thereby, control regarding the output current (IF column in Table 2) to be supplied to the light source 20 is also performed. Specifically, the control IC is configured to control the ON time of the switching element Q0 of the DC-DC converter based on a control signal from the microcomputer 51. For example, when the irradiation object 6 is "meat" or "fruit", the microcomputer 51 outputs twice the output current "IF × 2" according to Table 2, that is, twice that of "bread" and "fresh fish" A control signal is applied to the control IC so that the current is generated by the DC-DC converter. Thereby, the supply current with respect to LED1-LED4 is increased / decreased, and illumination intensity (brightness) can also be adjusted. In addition, since various dimming control techniques for adjusting the switching control of the switching power supply based on the dimming signal (PWM signal) from the dimmer are well known for adjusting the illuminance, the irradiation targets in Table 2 described above The dimming rate for each object 6 may be determined.

  As described above, according to the lighting device 100 according to the first embodiment, individual currents are supplied to the four types of LEDs 1 to 4 based on the information read from the storage unit of the microcomputer 51, and the LED 1 is generated. -The LED 4 can emit light, and the light can be irradiated to the irradiation object 6 with light of suitable illuminance and color temperature by mixing the respective lights. For example, when the irradiation target 6 is "pan", the LED 1 (color temperature 3000 k) and the LED 3 (color temperature 3500 k) are turned on, so these lights are mixed to realize the target color temperature 3250 k. can do.

(Manual switching by changeover switch 9)
The case where the irradiation light to the irradiation object 6 is changed using the changeover switch 9 will be described. When the switch signal is switched, the changeover switch 9 sends a signal to the microcomputer 51 in response to the switch to notify the microcomputer 51 of the switch setting position. When the switch setting position is set to other than "automatic", the microcomputer 51 performs lighting control predetermined for each switch setting position.

  For example, when four types of bread, meat, vegetables, and fresh fish are assumed as the irradiation object 6, five types of modes including an automatic mode are set in addition to the mode of each of the four types. By sliding the changeover switch 9, these five modes can be switched. When the changeover switch 9 is set to the leftmost end (the left end of the drawing in FIG. 3), panning is performed. If you slide to the opposite side from here, the mode switches in the order of meat, vegetables, and fresh fish. When it is set to the opposite end (the right side end in the drawing of FIG. 3), the manual selection function (that is, non-automatic control) by the changeover switch 9 becomes invalid, and automatic control by the image sensor 7 is performed.

  The manual control by the changeover switch 9 can be used when the image sensor 7 is not used, that is, when the automatic control is not necessary, or can be used to cancel the automatic control when the image sensor 7 does not operate properly. it can.

  For example, in a store that handles food, the changeover switch 9 preferably has marks such as bread, meat, vegetables, and fresh fish. For example, when "panning" is designated by moving the changeover switch 9, a signal including "pan designation information" indicating the "pan" is transmitted from the changeover switch 9 to the microcomputer 51. The signal including “pan designation information” may be generated by the changeover switch 9 or may be generated by the lighting device 5.

  In the storage unit of the microcomputer 51, suitable illuminance and color temperature corresponding to each of the plurality of types of irradiation objects 6, and lighting control content for realizing the same are stored in advance. When a signal including information indicating pan is transmitted from the change-over switch 9 to the microcomputer 51, the microcomputer 51 reads the illuminance and color temperature appropriate for "pan" from the storage unit, and the pan being the irradiation object 6 to be irradiated On the other hand, the lighting device 5 is operated so that appropriate light control can be performed. In the present embodiment, the microcomputer 51 supplies individual currents to the four types of LEDs 1 to 4 to emit light based on the appropriate illuminance and color temperature corresponding to the pan read from the storage unit. By mixing each light color, it is possible to irradiate light having an illuminance and color temperature suitable for the pan, which is the irradiation object 6 to be irradiated.

  As described above, according to the lighting apparatus 100 according to the first embodiment, the use of the image sensor 7 detects and determines what the irradiation target 6 the lighting device 10 is irradiating, and Appropriate light can be applied to the irradiation object 6.

  Further, according to the illumination device 100 according to the first embodiment, even when the product is replaced, the irradiation light can be changed manually by the changeover switch 9 or automatically by the image sensor 7. Therefore, it is not necessary to replace the lighting fixture 10.

(Detection of suspicious object / object absence by image sensor)
In the first embodiment, as an example of a preferred embodiment, when the image sensor 7 recognizes a suspicious thing that is not stored in the microcomputer 51 mounted on the lighting device 5, the microcomputer 51 of the lighting device 5 stores the information. The suspicious object recognition signal including is transmitted to the management terminal 8. The suspicious object may be recognized by, for example, collating an image of an object to be a suspicious object with detection information of the image sensor 7, for example, an image sensor for any of the registered images of the irradiation object 6. If the detection information of 7 does not match, it may be determined as a suspicious object. The management terminal 8 having received the suspicious object recognition signal notifies the administrator by displaying the information on the terminal screen. This makes it possible to detect suspicious objects early and accurately.

  In the first embodiment, as another example of the preferable embodiment, when the image sensor 7 can not recognize the irradiation target 6, the lighting device 5 transmits an object absence signal including the information to the management terminal 8 . In the determination of the absence of an object, for example, when the detection information of the image sensor 7 does not match any of the images of the irradiation objects 6 registered, it is determined as an absence (no product) and an absence of an object is determined. It may be something. Further, the detection information of the image sensor 7 may be compared and collated with “a predetermined determination condition determined in advance to determine that the object is absent”. The predetermined determination condition may be, for example, an image when the inside of each product case is imaged when the product is empty, when it is small, or when it is large. The management terminal 8 that has received the object absence signal notifies the administrator by displaying information that the irradiation object 6 cannot be recognized on the terminal screen. This makes it possible to detect sold-out products early and accurately. Thereby, the convenience of merchandise management can be improved.

  In the embodiment described above, the light source 20 has four LEDs, and the four LEDs 1 to 4 emit light of different types, that is, different color temperatures. However, the present invention is not limited to this.

The light source 20 may be provided with a plurality of LEDs having at least two different color temperatures. The color temperature may be at least two, and may be more or less than four.

  In addition, although the example in which the changeover switch 9 was installed, for example in the instrument case lower surface (the collar part 21a) was shown, the attachment position of the changeover switch 9 is not limited to this. For example, it may be configured to be installed on a wall hanging switch capable of lighting on / off or dimming, or may be installed on a remote control having the same function as this wall hanging switch. In addition, as the switch structure of the changeover switch 9, various types of switches that can receive an operation can be used, and the system and structure are not limited. For example, as a touch panel type, DIP switch type, push button type, or rotary type It is also good. When the changeover switch 9 is configured as a wireless terminal, this wireless terminal may be a dedicated terminal (remote control), and a control application program is installed in a general-purpose terminal (portable terminal, mobile phone, etc.) It is also good.

  In the above-described embodiment, bread, meat, fruit, or fresh fish is given as a specific example of the irradiation object 6. However, the present invention is not limited to this.
