  Recently, theft and injuries tend to increase and become a social problem. For example, so-called security systems that perform night illumination with LED lighting or monitor an intruder or suspicious person day and night with a surveillance camera have attracted attention.

  By the way, about LED illumination, generating with a solar panel in a daytime, charging a storage battery, and lighting LED by the electric power of a storage battery at night is performed (patent document 1).

  When the above-described security system is installed, not only the LED lighting device but also the surveillance camera can be operated with the power generated by the solar panel as a power source in a place where it is difficult to draw in the commercial power source.

  However, if the power generated by the solar panel is used to activate the LED lighting at night and the surveillance camera that should operate day and night, the function needs to be maintained more than the LED lighting function if the power supply voltage is insufficient depending on the weather conditions. There is a possibility that a trouble of so-called monitoring function stop, which causes the monitoring camera to stop functioning, may occur. Of course, if the solar panel or the storage battery is enlarged, troubles of stopping the monitoring function can be reduced, but the apparatus is increased in size and cost.

  In view of such problems, the present invention has an object to provide an independent power source for an LED lighting device with a monitoring camera control function that reduces the trouble of stopping the monitoring function without increasing the size and cost. And

  The independent power supply for the LED lighting device with the monitoring camera control function according to the present invention is a visible light LED module that performs night illumination while a monitoring camera is installed outside the lamp, and a motion sensor module that detects an object moving in the monitoring area An infrared LED module for ensuring the visibility of a night surveillance camera, and an LED illumination device with a surveillance camera control function that is mounted in a lamp, and a solar panel that receives sunlight to generate power, and the solar A storage battery for charging the panel power, the power of the storage battery as a power source, and driving the monitoring camera, motion sensor module and infrared LED module until reaching the lower limit voltage of the storage battery, the monitoring camera and motion sensor being less than the lower limit voltage The module and the infrared LED module are stopped, and the visible light LED module is It is bright until it reaches the first set voltage that is less than the full charge voltage of the battery, and it is the minimum between the first set voltage and the second set voltage that is less than the first set voltage and greater than or equal to the lower limit voltage of the storage battery. And a power supply control device that is driven to achieve brightness and stops the operation of the visible light LED module when the voltage is lower than a second set voltage.

  One of the features of the present invention is that only the monitoring camera function is operated up to the lower limit voltage of the storage battery. Thereby, when the monitoring is necessary, the trouble of the monitoring function can be reduced and the operation of the monitoring function can be guaranteed.

  The second feature of the present invention is that the visible light LED module is bright until it reaches a first set voltage that is less than or equal to full charge, and the minimum brightness is between the first set voltage and the second set voltage. And the operation of the visible light LED module is stopped at a voltage equal to or lower than the second set voltage. Thereby, according to the voltage of a storage battery, night illumination can be performed efficiently with at least the minimum brightness, and the power consumption of the storage battery can be reduced as much as possible.

  According to the present invention, when the battery voltage becomes lower than the lower limit voltage of the storage battery, the monitoring camera function is also stopped, thereby preventing a storage battery exhaustion failure.

  It is desirable to appropriately set the monitoring area by the monitoring camera according to the situation. Therefore, the motion sensor module and the infrared LED module are mounted on a separate lamp (secondary lamp) from the lamp mounted with the visible light LED module, and the separate lamp can set the infrared irradiation range arbitrarily. It is good to make it.

The infrared irradiation area of the module 21 and the detection area of the motion sensor module 22 can be arbitrarily set.

  The visible light LED module 20 performs night illumination by the light of the LED. The motion sensor module 22 detects the movement of a person or the like and drives the infrared LED module 21 and the monitoring camera 23. The infrared LED module 21 Infrared rays are emitted to the imaging area of the surveillance camera.

Then, a charge / discharge controller having a function of stopping the discharge output of the storage battery 101, 103 is a detection unit that detects the voltage of the storage battery that detects the voltage of the storage battery 101, and 104 is a comparison result of comparing the voltage of the storage battery 101 with a reference voltage. A / D converter / A / D converter 105, A / D converted current control signal 106, power source controller 106, 106 A current to the visible light LED module 107 according to the voltage of the storage battery 101 The power source unit of the visible light LED that controls the value, 106B is the infrared LED module 10 up to the lower limit voltage of the storage battery 101 And the infrared LED module power supply unit that drives the motion sensor module 109 to stop the infrared LED module 108 and the motion sensor module 109 at a voltage lower than the lower limit voltage of the storage battery 101, and 106C is in a state where the surveillance camera and the data logger 110 can be operated day and night. This is a camera drive power supply unit.

  In FIG. 4, 100 is a solar panel, 101 is a storage battery, 150 is a charge / discharge controller that controls charging and discharging, CMP1 to 3 are the voltage of the storage battery 150, the lower limit voltage of the storage battery 101, and the second and first set values (lower limit). First to third comparators 151 for comparing voltage <second set value <first set value), 151 has two inputs of the output signal of the second comparator CMP2 and the NOT signal of the output of the solar panel 100. A NAND circuit, 152 is an AND circuit having two inputs of the output signal of the third comparator CMP3 and the output of the solar panel 100, 153 is an N-type MOSFET in which the output of the NAND circuit 151 is connected to the gate, 154 The output of the third comparator CMP3 is connected to the gate, and the source / drain is connected between the resistance on the cathode side of the visible light LED and the ground. MOSFET, LM5002 is a step-up DC / DC converter IC for lighting the visible light LED.

  The charge / discharge controller 150, the first to third comparators CMP1 to CMP3, the NAND circuit 151, the AND circuit 151, and the N-type MOSFET 153 constitute the power supply control device 160. The power supply control device 160 is the power of the storage battery 101. Is used as a power source, and the monitoring camera 23, the motion sensor module 22 and the infrared LED module 21 are driven until reaching the lower limit voltage of the storage battery 101, and the monitoring camera 23, the motion sensor module 22 and the infrared LED module 21 are stopped below the lower limit voltage. The visible light LED module 20 is bright until it reaches a first set voltage that is less than or equal to the full charge voltage of the storage battery 101, and is a second value that is less than the first set voltage and greater than or equal to the lower limit voltage of the storage battery. Drive to the minimum brightness until the set voltage of And it is adapted to stop the operation of the visible light LED module 20 is less than the set voltage.

  Next, the operation will be described. In the daytime, the solar panel 100 and the storage battery 101 are connected by the charge / discharge controller 150. The solar panel 100 receives sunlight to generate power, and the storage battery 101 is charged with the power.

  The output of the charge / discharge controller 150 is in the day / night output state, and the voltage of the storage battery 101 divided by the resistors R6 and R7 is applied to the first to third comparators CMP1 to CMP3. The first to third comparators CMP1 to CMP3 are supplied with a voltage obtained by dividing the power supply voltage Vdd by the resistors R4 to R1 as a reference voltage.

  When the voltage of the storage battery 101 is equal to or higher than the lower limit voltage, the output of the first comparator CMP1 becomes “H”, an operation permission signal (Camera Enable) is output to the monitoring camera 23, and the monitoring camera 23 is in an operable state. Therefore, when the voltage of the storage battery 101 is equal to or higher than the lower limit voltage, the monitoring camera 23 is maintained in an operable state regardless of day and night. On the other hand, since the NOT signal output from the solar panel 100 is input to the NAND circuit 151 and the AND circuit 152, the visible light LED module 20, the motion sensor module 22, and the infrared LED module 21 stop operating.

  At night, the discharge controller 150 blocks the path between the solar panel 100 and the storage battery 101.

  When the voltage of the storage battery 101 is the first set voltage (first set value) equal to or lower than the full charge voltage, the outputs of the first, second, and third comparators CMP1 to CMP3 are all “H”. At night, the surveillance camera 23 is maintained in an operable state, while the AND circuit 152 receives an “H” signal from the first comparator CMP1 and an “H” signal that is a NOT signal from the solar panel 101. Since the operation permission signal (IR-LED / Motion-sensor Enable) is given from the AND circuit 152 to the motion sensor module 22 and the infrared LED module 21, when the motion sensor module 22 detects an infrared ray emitted from a human or the like. Since the infrared LED module 21 irradiates the monitoring area with infrared rays, a video of a suspicious person or an intruder is captured by the monitoring camera 23.

  The NAND circuit 151 receives the “H” signal of the second comparator CMP 2 and the “H” signal, which is the NOT signal of the solar panel 101, and the “L” signal is input to the gate of the N-type MOSFET 151. Thus, the N-type MOSFET 151 is turned OFF, the voltage of the main power supply is input to the Vin terminal of the boost DC / DC converter IC · LM5001, and the RT terminal and ground are connected to the SW terminal of the boost DC / DC converter IC · LM5001. An ON / OFF signal having a frequency determined by the resistance between them is output, a high voltage is induced in the inductor L, and applied to the visible light LED.

  On the other hand, the “H” signal of the third comparator CMP3 is given to the gate of the N-type MOSFET 154, the N-type MOSFET 154 is turned on, and the magnitude of the resistance between the cathode of the visible light LED and the ground is mutually The combined resistance value of the resistor R4 and the resistor R5 connected in parallel is obtained, and the visible light LED emits light and performs illumination.

  When the voltage of the storage battery 101 drops to a voltage between the first set value and the second set value (lower limit voltage <second set value <first set value), this time, the gate of the N-type MOSFET 154 3 is supplied with the “L” signal, the N-type MOSFET 154 is turned OFF, the resistance between the cathode of the visible light LED and the ground becomes the resistance value of the resistor R5, and the visible light LED has the minimum brightness. Now emit light and illuminate.

  At this time, the surveillance camera 23, the motion sensor module 22, and the infrared LED module 21 are maintained in an operable state.

  When the voltage of the storage battery 101 decreases to a voltage level between the second set value and the lower limit voltage of the storage battery 101, the NAND circuit 151 receives the “L” signal of the second comparator CMP2 and inputs the NAND circuit. The signal 151 is “H”, the N-type MOSFET 153 is turned ON, and the input voltage at the Vin terminal of the boost DC / DC converter IC · LM5001 is lower than the set value. The boost DC / DC converter IC · LM5001 Since the operation is stopped, the visible light LED stops operating. At this time, the surveillance camera 23, the motion sensor module 22, and the infrared LED module 21 are maintained in an operable state.

  When the voltage of the storage battery 101 falls below the lower limit voltage of the storage location 101, the AND circuit 152 receives the “L” signal of the first comparator CMP1 and the “H” signal that is the NOT signal of the solar panel 101, Since the signal of the AND circuit 152 becomes “L”, the motion sensor module 22 and the infrared LED module 21 stop operating, and the visible light LED also stops operating, so that a depletion failure of the storage battery 101 can be prevented.

  For example, when a 12V rated product is adopted for the storage battery, the full charge voltage is about 14V, and it can be said that the remaining amount is sufficient up to 12.6V. When the power consumption of the storage battery advances and becomes less than 11.5V, it means that the remaining amount is small (insufficient charging), and it is preferable to stop discharging at less than 11V.

  Therefore, the reference voltage of the first comparator CMP1 is 11V (lower limit voltage of the storage battery), the reference voltage of the second comparator CMP2 is 11.5V (second set value), and the reference voltage of the third comparator CMP3. Is set to 12.6V (first setting value), the FB terminal voltage of the booster type DC / DC converter IC · LM5001 is clamped to 1.26V, and the resistance R4 = 1Ω and the resistance R5 = 10Ω. When the voltage value of the storage battery is sufficient, the current of the visible light LED is 1.26 V / 0.909Ω = 1.4 A, and when the voltage is less than the second set voltage, the current of the visible light LED is 1 .26V / 10Ω = 0.126A.

Generally, in outdoor lighting having a crime prevention function, the function can be satisfied if the minimum illuminance is secured to about 1 to 3 lux. On the other hand, since several tens of lux is required for comfortable brightness in night illumination, it is usually desirable to ensure several tens of lux.
In the present invention, when the battery voltage is sufficient, the illumination is bright, and only when the battery voltage is significantly consumed, the brightness of the illumination is ensured to the minimum that can be prevented.

Further, when the voltage of the storage battery is between full charge voltage and 12.6 V, the current of the visible light LED is 1.4 A, and the monitoring camera function can be operated.
When the voltage of the storage battery is between 12.6 V and 11.5 V, the current of the visible light LED is 0.126 A, and the monitoring camera function can be activated.
When the voltage of the storage battery is between 11.5 V and the lower limit value, the visible light LED stops operating and the monitoring camera function can be activated.
When the voltage of the storage battery is less than the lower limit value, both the visible light LED and the monitoring camera function are stopped.
