  The present invention relates to a lighting control device that controls lighting and a vending machine including the same.

  In recent vending machines, as the main body of the vending machine increases in size, the product sample display section provided on the front of the vending machine also becomes larger, and the power consumption of lighting in the product sample display section has increased. Yes. Therefore, the human body detection sensor detects whether or not there is a person near the vending machine.

  The lighting control device for the conventional vending machine shown in FIG. 11 turns off the illumination of the product sample display section when there is no person near the vending machine, and the illumination of the product sample display section when a person approaches the vending machine. Therefore, the power consumption of the illumination of the product sample display unit can be reduced as compared with the case where the illumination of the product sample display unit is always lit.

  However, the lighting control device of the conventional vending machine shown in FIG. 11 operates when the vending machine is viewed from a distance because the product sample display section is turned off when there is no person near the vending machine. There was a risk that a person with a willingness to purchase would find another vending machine, and a person with a willingness to purchase could be missed.

  In view of the above situation, the present invention provides an illumination control device that can reduce power consumption and can easily recognize that it is operating even from a distance, and a vending machine including the same. The purpose is to do.

  In order to achieve the above object, an illumination control device according to the present invention includes an illumination unit and a human body detection sensor that detects the presence or absence of a person within a predetermined detection range, and the human body detection sensor detects a person. Control to turn on the illumination unit at a predetermined illuminance level when the human body detection sensor does not detect a person, and control to turn on the illumination unit at an illuminance level lower than the predetermined illuminance level. To do. In this configuration, the human body detection sensor has a hysteresis characteristic for switching between the case where the human body detection sensor detects a person and the case where the human body detection sensor does not detect a person, for example, the human body detection sensor When the person is continuously detected for a predetermined time of 1, the illumination unit is controlled to be lit at a predetermined illuminance level, and the human body detection sensor continuously detects the person for the second predetermined time. In some cases, the lighting unit is controlled to light at an illuminance level lower than the predetermined illuminance level.

  According to such a configuration, since the illuminance level of the illumination unit when the human body detection sensor is not detecting a person is lower than when the human body detection sensor is detecting a person, the power consumption is reduced. In addition, since the illumination unit is turned on even when the human body detection sensor does not detect a person, it can be easily recognized that it is operating from a distance.

  For example, a plurality of fluorescent lamps are used as the light source of the illuminating unit, and the number of fluorescent lamps to be lighted when the human body detection sensor does not detect a person is reduced as compared with the case where the human body detection sensor detects a person. Although a configuration for performing control is conceivable, a configuration using a plurality of LEDs (Light Emitting Diodes) as a light source of the illumination source is desirable in order to reduce the cost, size, and life of the illumination.

  Further, in the illumination control device having the above-described configuration, a plurality of LEDs are used as the light source of the illumination source, and a triac that switches electrical connection / disconnection between the AC power source and the illumination unit and the detection result of the human body detection sensor are used. A controller that controls the triac, a part of the plurality of LEDs and the rest of the plurality of LEDs are connected to each other bidirectionally, and the controller detects the person by the human body detection sensor. In the case where a predetermined gate voltage is applied to the gate of the triac both in a period in which the output voltage of the AC power supply is positive and in a negative period, and the human body detection sensor does not detect a person, A predetermined gate voltage may be applied to the gate of the triac in either one of the period in which the output voltage of the AC power supply is positive and the period in which the output voltage is negative. There. This simplifies the circuit configuration. Furthermore, when the human body detection sensor is not detecting a person, a control for applying a predetermined gate voltage to the gate of the triac during a period when the output voltage of the AC power supply is positive, and the output voltage of the AC power supply is It is desirable to switch the control to apply a predetermined gate voltage to the gate of the triac in a negative period at regular intervals. Thereby, leveling of the life can be achieved in a part of the plurality of LEDs and the rest of the plurality of LEDs.

  Further, in the illumination control device having the above-described configuration, a plurality of LEDs are used as the light source of the illumination source, and a triac that switches electrical connection / disconnection between the AC power source and the illumination unit and the detection result of the human body detection sensor are used. A controller that controls the triac, a part of the plurality of LEDs and the rest of the plurality of LEDs are connected to each other bidirectionally, and the controller detects the person by the human body detection sensor. In the case where a predetermined gate voltage is applied to the gate of the triac both in a period in which the output voltage of the AC power supply is positive and in a negative period, and the human body detection sensor does not detect a person, A predetermined gate voltage may be applied to the gate of the triac both during a part of the period when the output voltage of the AC power supply is positive and a part of the period when it is negative. . As a result, the circuit configuration is simplified, and the life can be leveled in a part of the plurality of LEDs and the rest of the plurality of LEDs.

  In the illumination control device having the above configuration, a plurality of LEDs are used as the light source of the illumination source, and a full-wave rectifier circuit that full-wave rectifies the output voltage of the AC power supply, A thyristor or triac that switches between automatic connection / disconnection and a control unit that controls the thyristor or triac according to a detection result of the human body detection sensor, and the control unit detects the person by the human body detection sensor. In the case where a predetermined gate voltage is applied to the gate of the thyristor or the triac in both the period in which the output voltage of the AC power supply is positive and the period in which it is negative, and the human body detection sensor does not detect a person In addition, in any one of a period in which the output voltage of the AC power supply is positive and a period in which the output voltage is negative, a predetermined gate voltage is applied to the thyristor or transistor. It may be applied to the acknowledgment of the gate. This simplifies the circuit configuration.

  In the illumination control device having the above configuration, a plurality of LEDs are used as the light source of the illumination source, and a full-wave rectifier circuit that full-wave rectifies the output voltage of the AC power supply, A thyristor or triac that switches between automatic connection / disconnection and a control unit that controls the thyristor or triac according to a detection result of the human body detection sensor, and the control unit detects the person by the human body detection sensor. In the case where a predetermined gate voltage is applied to the gate of the thyristor or the triac in both the period in which the output voltage of the AC power supply is positive and the period in which it is negative, and the human body detection sensor does not detect a person In addition, a predetermined gate voltage is applied to the thyristor or trie in both of a part of a period in which the output voltage of the AC power supply is positive and a part of a period in which the output voltage is negative. It may be applied to the gate of the click. This simplifies the circuit configuration.

  In the illumination control device having each configuration described above, an illuminance level lower than the predetermined illuminance level when the human body detection sensor is not detecting a person may be half of the predetermined illuminance level.

  Further, the illumination control device having each configuration described above includes an illuminance sensor that detects illuminance within a predetermined detection range, and when the illuminance detected by the illuminance sensor is equal to or higher than a predetermined level, the detection result of the human body detection sensor Regardless of the control, the illumination unit may be turned off. According to such a configuration, further energy saving can be achieved.

  Moreover, in order to achieve the said objective, it is good to use the illumination control apparatus of one of the said structures as an illumination control apparatus of the vending machine which controls the illumination of the goods sample display part provided in the front surface of a vending machine.

  According to the present invention, since the illuminance level of the illumination unit when the human body detection sensor is not detecting a person is lower than when the human body detection sensor is detecting a person, the power consumption can be reduced. In addition, since the illumination unit is turned on even when the human body detection sensor does not detect a person, it can be easily recognized that it is operating from a distance.

  Embodiments of the present invention will be described below with reference to the drawings. One structural example of the illumination control apparatus according to the present invention is shown in FIG.

  The lighting control device according to the present invention shown in FIG. 1 includes a triac 2, an LED array 3, a current limiting resistor 4, a human body detection sensor 5 that detects the presence or absence of a person within a predetermined detection range, and a human body. And a control unit 6 that controls the triac 2 in accordance with the output of the detection sensor 5. A triac 2, an LED array 3, and a current limiting resistor 4 are connected to the AC power source 1 in series. The LED array 3 includes a plurality of LED rows in which a plurality of LEDs are connected in series, and a half of all the LED rows are arranged so that the anode side is connected to the triac 2 and the cathode side is connected to the current limiting resistor 4. The other half of all the LED strings are arranged so that the anode side is connected to the current limiting resistor 4 and the cathode side is connected to the triac 2, and the number of LEDs connected in series is the same in all the LED strings.

The control unit 6 has a zero-cross detection unit (not shown) that detects a zero-cross of the output voltage of the AC power supply 1 (hereinafter also referred to as the power supply voltage V ₁ ).

When the human body detection sensor 5 detects a person, the control unit 6 always applies a predetermined gate voltage to the gate of the triac 2. Thus, when the power supply voltage V ₁ is positive, the absolute value of the power supply voltage V ₁ is equal to or greater than the total value of the forward voltages of the plurality of LEDs constituting the LED array (here, triac 2). The on-state resistance and the current limiting resistor 4 are ignored.), A current flows through the TRIAC 2, the LED row in which the anode side is connected to the TRIAC 2 and the cathode side is connected to the current limiting resistor 4 is lit, and the power supply voltage V ₁ Is negative when the absolute value of the power supply voltage V ₁ is equal to or greater than the sum of the forward voltages of the plurality of LEDs constituting the LED array (here, the ON resistance and current limiting resistance of the triac 2) 4 is ignored), a current flows through the triac 2, and the LED string in which the anode side is connected to the current limiting resistor 4 and the cathode side is connected to the triac 2 is lit. In this case, the waveforms of the current I ₂ flowing through the triac 2 and the voltage V ₂ across the triac 2 are as shown in FIG.

On the other hand, if the human body detection sensor 5 does not detect the person, the control unit 6, a period from the time of detecting the rising zero cross of the power supply voltages V ₁ to the fall time of detecting the zero crossing of the power supply voltages V _1, namely, A predetermined gate voltage is applied to the gate of the triac 2 while the power supply voltage V ₁ is positive. Accordingly, when the absolute value of the power supply voltage V ₁ is equal to or greater than the sum of the forward voltages of the plurality of LEDs constituting the LED array in the period in which the power supply voltage V ₁ is positive (here, triac 2 The on-resistance and the current limiting resistor 4 are neglected.), The LED row in which the anode side is connected to the triac 2 and the cathode side is connected to the current limiting resistor 4 is lit. In this case, the waveforms of the current I ₂ flowing through the triac 2 and the voltage V ₂ across the triac 2 are as shown in FIG. In the case where the person detecting sensor 5 does not detect the person, the control unit 6, a period from the time of detecting the rising zero cross of the power supply voltages V ₁ to the fall time of detecting the zero crossing of the power supply voltages V _1, namely, period the power supply voltage V ₁ is is positive, a control to apply a predetermined gate voltage to the gate of the triac 2, from the point of detecting the falling zero crossing of the supply voltages V ₁ to the point of detecting the rising zero cross of the power supply voltages V ₁ In this period, that is, during the period when the power supply voltage V ₁ is negative, the control to apply a predetermined gate voltage to the gate of the triac 2 is switched every certain time (for example, 1 hour) so that the anode side changes to the triac 2 The life of the LED string in which the cathode side is connected to the current limiting resistor 4 and the anode side to the current limiting resistor 4 and the cathode side to the triac 2 It is desirable to achieve equalization of the life of the LED string are connected.

The control unit 6 may include a phase detection unit (not shown) that detects the phase of the power supply voltage V ₁ instead of the zero cross detection unit, and may perform the following control.

When the human body detection sensor 5 detects a person, the control unit 6 always applies a predetermined gate voltage to the gate of the triac 2. Thus, when the power supply voltage V ₁ is positive, the absolute value of the power supply voltage V ₁ is equal to or greater than the total value of the forward voltages of the plurality of LEDs constituting the LED array (here, triac 2). The on-state resistance and the current limiting resistor 4 are ignored.), A current flows through the TRIAC 2, the LED row in which the anode side is connected to the TRIAC 2 and the cathode side is connected to the current limiting resistor 4 is lit, and the power supply voltage V ₁ Is negative when the absolute value of the power supply voltage V ₁ is equal to or greater than the sum of the forward voltages of the plurality of LEDs constituting the LED array (here, the ON resistance and current limiting resistance of the triac 2) 4 is ignored), a current flows through the triac 2, and the LED string in which the anode side is connected to the current limiting resistor 4 and the cathode side is connected to the triac 2 is lit. In this case, the waveforms of the current I ₂ flowing through the triac 2 and the voltage V ₂ across the triac 2 are as shown in FIG.

On the other hand, when the human body detection sensor 5 does not detect a person, the controller 6 determines that the phase of the power supply voltage V ₁ is π / 2 to π and the phase of the power supply voltage V ₁ is 3π / 2 to 2π. In a certain period, a predetermined gate voltage is applied to the gate of the triac 2. Thus, when the phase of the power supply voltage V ₁ is π / 2 to π, the absolute value of the power supply voltage V ₁ is equal to or greater than the sum of the forward voltages of the plurality of LEDs constituting the LED array. (Here, the on-resistance of the triac 2 and the current limiting resistor 4 are ignored), the LED string in which the anode side is connected to the triac 2 and the cathode side is connected to the current limiting resistor 4 is lit, and the power supply voltage V ₁ When the phase is 3π / 2 to 2π, when the absolute value of the power supply voltage V ₁ is equal to or greater than the sum of the forward voltages of the plurality of LEDs constituting the LED array (here, the triac 2 is turned on) The resistor and the current limiting resistor 4 are ignored.), The LED row in which the anode side is connected to the current limiting resistor 4 and the cathode side is connected to the triac 2 is lit. In this case, the waveforms of the current I ₂ flowing through the triac 2 and the voltage V ₂ across the triac 2 are as shown in FIG. As is apparent from FIG. 4, the lifetime of the LED string in which the anode side is connected to the triac 2 and the cathode side is connected to the current limiting resistor 4, and the lifetime of the LED string in which the anode side is connected to the current limiting resistor 4 and the cathode side is connected to the triac 2 Leveling can be achieved.

  The illumination control device according to the present invention shown in FIG. 1 reduces the illuminance of the LED array 3 when the human body detection sensor 5 is not detecting a person as compared with the case where the human body detection sensor 5 is detecting a person. Therefore, the power consumption of the LED array 3 can be reduced, and the LED array 3 is lit even when the human body detection sensor 5 is not detecting a person, so that the LED array 3 is operating even from a distance. It can be easily recognized.

  In addition, the lighting control device according to the present invention shown in FIG. 1 uses an AC power source for driving the LED array 3 instead of a general DC power source as an LED driving power source. The drive circuit has a simple configuration.

  Next, another configuration example of the illumination control device according to the present invention is shown in FIG. 5 that are the same as those in FIG. 1 are denoted by the same reference numerals.

  The lighting control device according to the present invention shown in FIG. 5 includes a thyristor 2A, an LED array 3A, a current limiting resistor 4, a human body detection sensor 5 that detects the presence or absence of a person within a predetermined detection range, and a human body. A control unit 6A for controlling the thyristor 2A according to the output of the detection sensor 5 and a diode bridge 7 are provided. The input side of the diode bridge 7 is connected to the AC power source 1, and the thyristor 2 </ b> A, the LED array 3 </ b> A, and the current limiting resistor 4 are connected in series to the output side of the diode bridge 7. The LED array 3A has a plurality of LEDs connected in series, arranged in parallel, and all LED arrays are arranged in such a way that the anode side is connected to the thyristor 2A and the cathode side is connected to the current limiting resistor 4, and connected in series. In this configuration, the number of LEDs that are used is the same in all LED rows.

Controller 6A includes zero crossing detector for detecting the zero crossing of the supply voltages V ₁ (not shown).

When the human body detection sensor 5 detects a person, the control unit 6A always applies a predetermined gate voltage to the gate of the thyristor 2A. As a result, during the period when the power supply voltage V ₁ is positive and the period when the power supply voltage V ₁ is negative, the output voltage V ₇ of the diode bridge 7 is the sum of the forward voltages of the plurality of LEDs constituting the LED array. When the value is greater than or equal to the value (here, the on-resistance of the thyristor 2A and the current limiting resistor 4 are ignored), a current flows through the thyristor 2A, and all the LED columns of the LED array 3A are lit. In this case, the waveforms of the current I _2A flowing through the thyristor 2A and the voltage V _2A across the thyristor 2A are as shown in FIG.

On the other hand, if the human body detection sensor 5 does not detect the person, the control section 6A, the period from the time of detecting the rising zero cross of the power supply voltages V ₁ to the fall time of detecting the zero crossing of the power supply voltages V _1, namely, A predetermined gate voltage is applied to the gate of the triac 2 while the power supply voltage V ₁ is positive. Thus, when the power supply voltage V ₁ is positive, the output voltage V ₇ of the diode bridge 7 is equal to or greater than the sum of the forward voltages of the plurality of LEDs constituting the LED array (here, the thyristor). 2A on-resistance and current limiting resistor 4 are ignored.), A current flows through thyristor 2A, and all LED rows of LED array 3A are lit. In this case, the waveforms of the current I _2A flowing through the thyristor 2A and the voltage V _2A across the thyristor 2A are as shown in FIG.

Further, the control unit 6A may include a phase detection unit (not shown) that detects the phase of the power supply voltage V ₁ instead of the zero cross detection unit, and may perform the following control.

When the human body detection sensor 5 detects a person, the control unit 6A always applies a predetermined gate voltage to the gate of the thyristor 2A. As a result, during the period when the power supply voltage V ₁ is positive and the period when the power supply voltage V ₁ is negative, the output voltage V ₇ of the diode bridge 7 is the sum of the forward voltages of the plurality of LEDs constituting the LED array. When the value is greater than or equal to the value (here, the on-resistance of the thyristor 2A and the current limiting resistor 4 are ignored), a current flows through the thyristor 2A, and all the LED columns of the LED array 3A are lit. In this case, the waveforms of the current I _2A flowing through the thyristor 2A and the voltage V _2A across the thyristor 2A are as shown in FIG.

On the other hand, if the human body detection sensor 5 does not detect the person, the control section 6A, and duration the phase of the supply voltage V ₁ is a π / 2~π, the phase of the power supply voltage V ₁ is at 3π / 2~2π In a certain period, a predetermined gate voltage is applied to the gate of the thyristor 2A. As a result, the output voltage V ₇ of the diode bridge 7 constitutes an LED string during the period in which the phase of the power supply voltage V ₁ is π / 2 to π and the period in which the phase of the power supply voltage V ₁ is 3π / 2 to 2π. When the forward voltage of the plurality of LEDs is equal to or greater than the total value (here, the on-resistance and the current limiting resistor 4 of the thyristor 2A are ignored), a current flows through the thyristor 2A, and the LED array 3A All LED rows are turned on. In this case, the waveforms of the current I _2A flowing through the thyristor 2A and the voltage V _2A across the thyristor 2A are as shown in FIG.

  The illumination control device according to the present invention shown in FIG. 5 reduces the illuminance of the LED array 3A when the human body detection sensor 5 is not detecting a person as compared with the case where the human body detection sensor 5 is detecting a person. Therefore, the power consumption of the LED array 3A can be reduced, and the LED array 3A is lit even when the human body detection sensor 5 is not detecting a person, so that it can be operated even from a distance. It can be easily recognized.

  In addition, the illumination control device according to the present invention shown in FIG. 5 uses an AC power source for driving the LED array 3A instead of a general DC power source as an LED driving power source. The drive circuit has a simple configuration.

  Next, still another configuration example of the illumination control apparatus according to the present invention is shown in FIG. In FIG. 9, the same parts as those in FIG.

  The illumination control device according to the present invention shown in FIG. 9 has an illuminance sensor 8 that detects illuminance within a predetermined detection range in the illumination control device according to the present invention shown in FIG. 1 in order to further save energy. Is added, and the control unit 6 is replaced with the control unit 6B.

  When the illuminance detected by the illuminance sensor 8 is equal to or higher than a predetermined level, the control unit 6B does not apply a predetermined gate voltage to the gate of the triac 2 regardless of the detection result of the human body detection sensor 5. Thus, when the illuminance detected by the illuminance sensor 8 is equal to or higher than a predetermined level, the LED array 3 is turned off regardless of the detection result of the human body detection sensor 5. On the other hand, when the illuminance detected by the illuminance sensor 8 is less than a predetermined level, the control unit 6B performs the same control as the control unit 6. For example, the illuminance detected by the illuminance sensor 8 is greater than or equal to a predetermined level at daytime or the like, and the illuminance detected by the illuminance sensor 8 is less than the predetermined level at night or the like.

  The same configuration change as the configuration change from the illumination control device according to the present invention shown in FIG. 1 to the illumination control device according to the present invention shown in FIG. 9 is applied to the illumination control device according to the present invention shown in FIG. You may go.

  Further, in the above-described embodiment, the hysteresis switching is not provided in the switching of control between the case where the human body detection sensor 5 detects a person and the case where the human body detection sensor 5 does not detect a person. You may make it have. For example, when the human body detection sensor 5 continues to detect a person for a first predetermined time, the LED array is controlled to be lit at a predetermined illuminance level. When no person is detected continuously, the LED array may be controlled to be lit at an illuminance level lower than the predetermined illuminance level.
