It relates to an intelligent LED luminaire capable of communication equipped with one sensor.

Currently, many electric wires are installed in the sky, and many electric power outlets that install electric wires underground are being installed in the form of tunnels, and these underground electric power outlets use fluorescent lamps as lighting equipment to illuminate the underground space of the electric power district. In addition, these fluorescent lamps consume a lot of power and have a short lifespan, and thus economic and use efficiency are deteriorating.

In addition, since the underground space in the power ward is installed at least several tens of meters underground, it is impossible to remove moisture, so a waterproof fluorescent lamp that is resistant to moisture is used, and this waterproof fluorescent lamp is a structure that is divided into a junction box and a fluorescent lamp. Since the wires of each junction box and fluorescent lighting fixtures must be connected together, the wiring work is very difficult and takes a long time because it is done by hand.

In addition, since these LED luminaires always have a ballast that is supplied with power, they always have a state of supplying power, so there is a problem that power is consumed even though they are not used, and each LED luminaire is connected with a wire. Since many are installed in a row, there is a problem that a lot of cost and effort are required for installation.

The present invention was devised to solve the above problems, and it is possible to accurately detect the presence or absence of a human body in normal times to adjust the brightness, and at the same time prevent malfunction of the sensor due to an increase in attention temperature, vibration by wind, and other light sources.

The intelligent LED luminaire capable of communication equipped with a sensor according to the present invention provides a power supply unit 110 receiving and rectifying commercial power and supplying the rectified power through the power supply unit 110, as shown in FIG. An LED lighting unit 120 that is supplied and turned on, a human body sensing unit 130 that detects the presence or absence of a human body, a light measurement unit 140 that measures light around the LED lighting unit 120, and the surrounding environment Accordingly, a setting value receiving unit 150 for adjusting the sensing distance of the human body sensing unit 130, whether or not the light measuring unit 140 is used, adjusting the brightness of the LED lighting unit 120, and adjusting ON/OFF time from the outside, and , Manually adjusting the sensing distance of the human body sensing unit 130 from the outside according to the surrounding environment, whether the light measuring unit 140 is used, adjusting the brightness of the LED lighting unit 120, and manually adjusting the ON/OFF time A setting unit 160, a temperature sensing unit 170 for sensing the temperature around the LED lighting unit 120, the human body sensing unit 130, a light measuring unit 140, a setting value receiving unit 150, By receiving the control signal of the manual setting unit 160 and the ambient temperature of the temperature sensing unit 170, the standby power flowing from the power supply unit 110 to the LED lighting unit 120 is reduced, and the LED lighting unit 120 ), an integrated control unit 180 that selectively turns ON/OFF the power supplied to the LED and controls the driving and brightness of the LED lighting unit 120, and a communication transmission/reception unit connected to the integrated control unit 180 and capable of transmitting and receiving externally. (200), a plurality of sub-gateways 210 that can transmit and receive from the communication transceiving unit 200 and are configured in an adjacent area to transmit and receive from the outside, and each sub-gateway 210 includes the communication transceiving unit 200 ) And transmission/reception is possible, and it is configured in an adjacent area so that transmission/reception is possible from the outside, and by using a plurality of sub-gateways 210 configured in a conset part of the room, communication with the LED luminaires grouped into a plurality of groups is set without communication obstacles. LED lights Management and control.

In addition, a main gateway 220 capable of transmitting and receiving with the plurality of sub-gateways 210 and transmitting a control signal to the sub-gateway 210 or transmitting a signal received from the sub-gateway 210 to the outside, and the main It is possible to transmit/receive with the gateway 220 and transmit a control signal to the sub-gateway 210 through the main gateway 220 or receive a signal received through the sub-gateway 210 to manage the LED lamp 120 And it comprises a management server 230 to control.

On the other hand, in the embodiment of the present invention, the LED luminaire may use any one of an LED downlight, an LED indoor luminaire, an LED tunnel luminaire, an LED floodlight, and an LED street luminaire.

The power supply unit 110 is divided into a primary power supply and a secondary power supply.

The primary-side power source includes a commercial power source 111, a filter unit 112, a rectifier 113, a power stabilization unit 114, and an AC/DC conversion unit 115.

Here, the commercial power supply 11 is AC power, and the filter unit 112 receives the AC power and filters AC power noise to output AC power.

The rectifier 113 is a bridge rectification circuit, receives commercial power filtered by the filter 112, converts it into a DC voltage, and outputs it.

For example, when an input voltage of 220V and 60Hz is input, the rectifier 113 may rectify and output a full-wave rectified pulsating wave form of peak 300V.

The power stabilization unit 114 receives and smoothes the input voltage rectified by the rectification unit 113 to stabilize the power to supply stable power to the LED lighting unit 120. At this time, the power stabilization unit 114 is composed of a capacitor of 2.2 ㎌ or more. As the capacitance of the capacitor increases, the power factor decreases as the voltage shifts in phase.

The AC/DC conversion unit 115 converts the power stabilized by the power stabilization unit 114 into DC power and outputs the converted power.

The secondary-side power source includes an AC/DC conversion unit 190. The AC/DC conversion unit 190 converts and outputs DC power to the LED lighting unit 120.

The LED lighting unit 120 may be a single LED lighting module or a plurality of LED lighting modules. Alternatively, it may be a group of a plurality of LED lighting devices installed in an indoor space.

The human body sensing unit 130 is a malfunction caused by sunlight/play, that is, there is light in a band detectable by the PIR sensor and the microwave sensor in the sunlight, and the light is in motion. By converting the size of the signal frequency component to the vibration caused by the vibration, the vibration caused by the movement of the person upstairs, and the vibration caused by the wind, a signal other than the human body detection value can be selected, and the magnitude of the signal frequency component for the vibration that always occurs is analyzed.

Meanwhile, a human body detection sensor may malfunction due to a sudden change in ambient temperature and a low frequency output generated from a moving object. The human body sensing unit 130 selects a signal other than a human body detection value by converting the size of the signal frequency component. The heat fluctuation according to the surrounding situation changes slowly (temperature change according to the change of time, etc.), and the fluctuation of heat according to the surrounding situation does not repeat rapidly (the temperature change rapidly fluctuates due to ventilation, etc.).

For example, LED luminaires are often exposed to the outside in common areas in apartments. In the case of a human body sensor, a change in ambient temperature can be mistaken as a human being. Therefore, the human body sensing unit 130 employs a malfunction prevention technology that detects only the movement of the human body and the vehicle by analyzing and selecting the inherent frequency of each element to be measured.

An abnormal pulse removal unit 131 for removing abnormal pulses included in the human body detection signal by receiving a human body detection signal after sensing a human body by the human body sensing unit 130, and an abnormal pulse from the abnormal pulse removal unit 131 And a signal amplifying unit 132 amplifying and outputting the removed human body detection signal.

The abnormal pulse removing part 131 uses a ferrite bead and an LC type peel. In this case, when the ferrite bead is used, the carrier frequency impedance may be insufficient depending on the self-resonant frequency, and there is an inconvenience of having to change the time constant every time a PCB is designed.

Therefore, the LC-type fill has a high magnetic flux density HM2A T0803 that maintains a high L value even with a small number of turns of the common mode filter, and the winding is configured in a symmetrical type of 10 turns. RESISTANCE Max 21mΩ is configured so that noise level is significantly removed.

The signal amplifying unit 132 is an interface between a sensor and a signal amplifying unit, which is the most sensitive component in the signal line. The signal in this section outputs a very low signal. Accordingly, the signal amplification unit 132 is amplified through the first amplification and the second amplification, and then an analog level is output. At this time, the output width generally has a pulse width of 100ms ~ 600ms when detected once. Also, it must go through the stabilization time of the amplifier, and it has a stabilization time of about 4 to 10 seconds after power is applied.

The human body sensing unit 130 often generates a low-frequency output from an object moving within the sensor range. The frequency of the human body response signal depends on the moving speed of the object, and the amplitude varies depending on the distance, reflectance, and size. That is, the human body sensitization signal operates in proportion to the object's frequency fd and the object velocity v, and the angle of the moving object reduces the frequency of the human body sensitization sensor.

Therefore, the present invention does not discriminate only with a simple amplification level, but in order to accurately discriminate three factors, the frequency fd of the object is the object velocity v and the time t, the amplification degree and RF noise immunity are enhanced.

On the other hand, a low pass filter (not shown) is configured at the output terminal of the signal amplifying unit 132 to reduce the influence of the open gain deviation of the signal amplifying unit 132. That is, distortion of the abnormality detection signal can be suppressed.

In this way, the human body sensing unit 130 detects the movement of the human body, removes the abnormal pulse of the input signal (RF signal and power noise), and amplifies the signal (the human sensitization signal is the frequency fd of the object is the speed of the object v and the time t). It is amplified with 3 element discrimination signals)

The integrated control unit 180 determines whether to calculate the PRI index according to the human body detection signal, temperature coefficient, and ambient brightness by selecting the human body detection signal frequency, and calculates the human body detection index (PRI).

At this time, if it is determined that the PRI is greater than 70%, data is transmitted through Bluetooth (Ble) or Wi-Fi communication so that the LED luminaires enclosed in a group can be turned ON and DIM.

That is, the sensor measurement information and the current state are transmitted to Bluetooth (Ble) + Wi-Fi, mobile phone (Hand phone), etc. when requesting data from Bluetooth through the communication transmission/reception unit 200.

And if the PRI is greater than 70%, the LED luminaire is turned ON and DIM is performed. When 70%> PRI> 35% is determined, the additional signal and frequency analysis are re-produced to recalculate the PRI index, and when PRI <35% is determined, the previous The PRI index is erased and human movement is detected again to recalculate the PRI index.

The light measuring unit 140 is configured to replace a CdS cell that has been widely used for automatic dimming of LED lighting according to ambient brightness or switching of a surveillance camera at night.

The light measuring unit 140 uses a photo transistor, and the photo transistor is mounted on a general frit substrate.

The light measuring unit 140 is equipped with a filter function to block infrared light, and the peak sensitivity is about 560 nm. In general, when a white light-emitting diode is irradiated at an illuminance of 100 GHz, the light current is a standard 33 ㎂. The maximum dark current is 0.1㎂, and the standard angle is ±20 degrees at half-value angle (the angle at which the photocurrent is reduced in half).

The light measuring unit 140 is a shell-type illuminance sensor whose spectral sensitivity is close to that of a human field of view, and compared with the conventional technology, the difference in photocurrent due to the type of light source is small and the spectral sensitivity can be adjusted while relatively lowering the manufacturing cost. have.

For example, when irradiating an incandescent lamp and a fluorescent lamp, the ratio of the photocurrent is usually about 1.7, but the light measuring unit 140 tends to be as low as 1.4.

In addition, it is also characterized by less change in spectral sensitivity due to the incident angle of light. The filter serves to selectively transmit a part of the spectrum and block the rest.

When the light measuring unit 140 measures the ambient illuminance of the LED lighting unit 120 and supplies it to the integrated control unit 180, the integrated control unit 180 measures the illuminance value measured by the light measuring unit 140 When the illuminance value is greater than the set value by comparing with the set value, the LED lighting unit 120 is turned off or dimmed to maintain a constant illuminance.

On the other hand, when the measured illuminance value is smaller than the set value, the LED lighting unit 120 is turned on or dimmed to maintain a constant illuminance.

The setting value receiving unit 150 is installed at a height of 2 to 6M indoors, and 3 to 12M for outdoor LED luminaires according to the present invention. That is, in order to change the setting value once installed, the setting is possible only by using the equipment, and in this case, a lot of cost is incurred.

Therefore, the setting value receiver 150 is applied to the product in order to change the setting value of the installed product from the default value for the LED luminaire, that is, a remote control, Bluetooth + gateway, Bluetooth + zigbee, Bluetooth + at a distance from the LED luminaire. Settings can be changed with Wi-Fi, Bluetooth + RS485, or mobile phone.

It is possible to remotely control the sensing distance according to the surrounding environment in which the LED luminaire is installed, whether or not to use a light sensor, to set the minimum and maximum brightness values, to set ON/OFF time, brightness maintenance time, and whether or not to use communication.

The manual setting unit 160 adjusts the sensing distance according to the surrounding environment in which the LED luminaire is installed, when the setting value receiving unit 150 is unable to perform communication, whether or not an optical sensor is used, minimum, maximum. You can manually set the brightness value setting, ON/OFF time, brightness maintenance time, whether or not to use communication.

On the other hand, since the intelligent LED luminaire capable of communication equipped with the sensor of the present invention is not limited to any one product, it is possible to mass-produce and immediately manually change the setting according to various LED luminaires to increase the applicability of the product.

In addition, the manual setting unit 160 is used when manual setting is required due to loss of a wireless device for operating the setting receiving unit 150.

The temperature sensing unit 170 measures a change in an internal resistance value of the ambient temperature, calculates the current temperature according to the temperature coefficient of resistance, and transmits the change to the integrated control unit 180.

The temperature sensing unit 170 measures to correct a temperature zero error and a temperature span error of the sensor. Here, the temperature zero error is the sensor output level change due to temperature change when the sensor input is set to 0, and the temperature span error is the sensor output due to temperature change when the input is set as the rated input (100% FS). It's a level change.

The integrated control unit 180 includes a reverse current prevention unit 181, a power stabilization unit 182, an AC/DC conversion unit 183, a low power timer 184, and a control unit 185.

The reverse current prevention unit 181 serves to maintain a high power factor without shifting the phases of voltage and current even when a capacitor having a high capacitance is used in the power stabilization unit 114.

That is, the reverse current prevention unit 181 is configured as a circuit configured with high input/output conversion efficiency and low self-standby power of 20 mW.

The power stabilization unit 182 uses a capacitor having a high capacitance like the power stabilization unit 114, but the voltage and current according to the capacitance value from the reverse current prevention unit 181 to the power stabilization unit 114 are High power factor can be maintained without shifting the phase.

The AC/DC conversion unit 183 receives and converts the stabilized power from the power stabilization unit 182 and outputs the converted power.

The low-power timer 184 operates by receiving the power converted by the AC/DC converter 183 to selectively block unnecessary signals.

Further, the control unit 185 receives an operation signal from the low-power timer 184 and cuts off the power supplied to the LED lighting unit 120 through the signal transmission unit 186.

The low-power timer 184 shortens the program routine of the control unit 185 when the human body is not detected through the human body sensing unit 130 for standby power consumed by 10 ㎂, and turns off unnecessary signals to reduce standby power by 0.5W. Implemented in less than.

The low-power timer 184 operates the integrated control unit 180 every 1sec to 10min (time adjustable) to continuously operate the control unit 185 when the human body is sensed, and AC/DC conversion through the signal transmission unit 186 The dimming of the part 115 is turned on so that the LED luminaire is turned on.

On the other hand, standby power is power consumed because the main power is applied even if the output of the LED lighting is turned off using a sensor. During standby, the parts that are running consume power.

The control unit 185 analyzes and selects the inherent frequency of each element measured by the human body sensing unit 130, the light measuring unit 140, and the temperature sensing unit 170, and detects only the movement of the human body and the vehicle. Can prevent malfunction of the product.

In general, malfunctions for RF signals differ depending on the sensor. In particular, the PIR sensor and microwave sensor work even with a fairly small external wireless signal.

In addition, the control unit 185 has a band of light that can be detected by the PIR sensor and the microwave sensor in the sunlight, and the light is in motion. , It converts the size of the signal frequency component by vibration caused by wind and selects the signal, not the human body detection value.

The control unit 185 analyzes the magnitude of a signal frequency component for shaking that always occurs.

Meanwhile, the human body detection sensor may malfunction due to a sudden change in ambient temperature.

The control unit 185 selects a signal other than a human body detection value by converting the magnitude of the signal frequency component. The fluctuation of heat according to the surrounding conditions changes slowly (temperature changes over time, etc.). Heat fluctuations due to surrounding conditions do not repeat rapidly (such as temperature fluctuations rapidly due to ventilation).

For example, apartment common areas are often exposed to the outside. In the case of a human body sensor, a change in ambient temperature can be mistaken as a human being.

The communication transmission/reception unit 200 uses Bluetooth or Wi-Fi communication and constitutes a low-power wireless wireless communication method.

Conventionally, communication was performed by directly connecting a gateway, an external manipulator and a plurality of LED luminaires. Since only one gateway exists in a home or office, when communicating with a large number of LED luminaires, it is in a state of being difficult to control due to communication failure due to surrounding walls, objects, and strength of communication.

2 is a schematic configuration diagram showing an intelligent LED luminaire capable of communication equipped with a sensor according to the present invention.

As shown in Fig. 2, a plurality of intelligent LED luminaires 100 capable of communication equipped with sensors are arranged at regular intervals, and a plurality of groups in a state in which the plurality of LED luminaires 100 are grouped into one group. It is separated into (A, B).

Meanwhile, in the present invention, a plurality of LED luminaires 100 are separated into groups A and B, respectively, but the groups may be further divided depending on the indoor space.

Accordingly, the present invention further configures a plurality of sub-gateways 210 serving as a repeater between a plurality of LED luminaires 100 and the main gateway, and directly with the integrated control unit 180 by plugging into a wall outlet of the office space. Communication may be performed, and communication of the integrated controller 180 may be facilitated by connecting to an intermediate outlet according to a transmission/reception state.

Meanwhile, a Bluetooth communication module (Ble) is mounted on the plurality of LED luminaires 100, and a command is received from the sub-gateway 210 and executed. At this time, the sub-gateway 210 receives control signals such as dimming, on, off, etc. of the LED luminaire 100 transmitted through the main gateway 220 from an external management server 230, and the integrated control unit 180 ).

A separate sensor may be attached to the one LED luminaire 100, and the value detected by the sensor is transmitted to the sub-gateway 210, and the sub-gateway 210 detects the remaining LED luminaires 100 again. Can carry signals.

These detection signals have a specific advertising interval, and a posting period is transmitted every this period. The longer the cycle, the more power consumption can be reduced.

There is only a problem that the response from the receiving device (management server) is slow, but the delay caused by data transmission can be solved because the data capacity is simplified to 2 to 16 bits.

If the receiving device can send an additional data request to scan response data, it can also respond with data.

Meanwhile, the sub-gateway 210 can be transformed into a Bluetooth (Ble) + Wi-Fi, Bluetooth (Ble) + ZigBEE, Bluetooth (Ble) + RS485 communication method.

At this time, the management server 230 and the main gateway 220 are configured to transmit and receive data through a cloud method 250, and the main gateway 230 is controlled through the administrator's terminal 240 You can also operate the LED luminaire by receiving.

In the space adjacent to the LED lamp 100 according to the present invention, a plurality of sub-gateways 210 serving as repeaters capable of transmitting and receiving with the communication transmission/reception unit 200 are additionally installed at an outlet of the indoor space to Even if communication is not smoothly performed, communication with the communication module 101 of the LED lamp 100 is possible through each of the sub gateways 210.

Therefore, when operating the LED luminaire 100 through the external management server 230 or the administrator's terminal 240 or receiving data from the LED luminaire 100, a plurality of sub-gateways 210 and main gateway 220 are used. By using it, dimming, ON, OFF of the LED luminaire 100 can be effectively controlled.

In addition, by using the communication transceiving unit 200 capable of transmitting and receiving Bluetooth, it is possible to supplement the conventional communication method and a lot of power consumption, which is a disadvantage of the existing Bluetooth.

The LED control unit 180 uses an insulation type LED converter that performs a switching operation for current control with respect to the DC voltage feedback and dimmed from the DC power supply of the primary side and the power supply of the secondary side.

3 is a diagram for describing an intermittent oscillation method.

In the intermittent oscillation method, the switching operation of the power element of the switching power supply is continued for a certain period of time and then the switching operation is stopped for a certain period of time, thereby intermittent operation. By reducing the number of switching per unit time compared to the high switching frequency (65Kh) in normal operation, switching loss is reduced and power efficiency in standby is improved. As shown in FIG. 3, when the load power decreases, the oscillation stop period is lengthened, so that power consumption can be significantly reduced.

4 is a diagram for explaining a process of determining a movement of a human body by converting a signal according to a movement of the human body and a frequency component size of the signal.

As shown in FIG. 4, when the human body is seated, there is no change in signal, and when the human body is standing up, a slight change in signal occurs. And when walking or running, the signal changes rapidly.

When the change of the signal is received and converted into the size of the frequency component of the signal, when the sum of the human body reactions is maintained for t seconds or more, it is determined that there is a person.

5 is a graph showing changes in current of a light source according to ambient temperature.

As shown in FIG. 5, it can be seen that the measured current value of sunlight (Light source A) according to the ambient temperature is larger than that when the white LED is irradiated.

This is an optical sensor that has to be integrated into or installed around an LED luminaire, so it is possible to maintain constant ambient illumination desired by consumers by precisely analyzing only the surrounding brightness and adjusting the brightness of the LED luminaire accordingly.

6 is a graph showing spectral sensitivity characteristics.

As shown in FIG. 6, it can be seen that the intensity of the response to the amount of energy or light incident at a specific wavelength is similar to that of a person.
