Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 10, the LED lamp is a dimming LED lamp (1') equipped with a microwave sensor according to the present invention, an LED substrate (10'), a microwave sensor module (20'), a heat sink (30). '), a control module 40' and a dimming converter 50'.

The LED substrate 10' is a substrate on which the LED 11 (Light Emitting Diode') is installed and, as shown in the drawing, has a predetermined width W1' and may be formed to have a long length direction. 1 and 2 show that the LED 11 ′ installed on the LED substrate 10 ′ is installed on the upper surface to explain the features of the present invention, but the direction in which the LED 11 ′ is installed emits light. It is installed in the direction of That is, when the LED lamp 1'is installed in the upper part of the room, the LED 11' is installed to irradiate light on the floor surface. In this case, the installed LED 11 ′ may be installed by a surface mounting technology (SMT) method mounted on the LED substrate 10 ′. SMT refers to a general technology that mounts an LED on the surface of a board without penetrating the lead of the LED through the board.

Accordingly, the rear surface of the LED substrate 10' installed by the SMT method has no electrical wiring. Depending on the design conditions, the LED substrate 10 ′ may be formed of a metal substrate. The microwave sensor module 20' detects a moving object and outputs it as a detection signal, and includes a microwave sensor, an antenna unit 21', and a sensor control unit. The microwave sensor detects a moving object (the human body') using the Doppler radar principle, and a transmission antenna that transmits frequencies and a reception antenna that receives the reflected frequency from the transmission antenna. Consists of including. At this time, the frequency band mainly used is 10~20Ghz high frequency. Here, the transmitting antenna and the receiving antenna are configured to be spaced apart as much as possible to minimize interference with each other.

For example, when the transmitting antenna is installed to be located on one side of the microwave sensor, the receiving antenna is configured to be installed on the other side. Accordingly, in the dimming LED lamp equipped with a microwave processor according to the present invention, the microwave sensor module 20' is an antenna part 21 of the microwave sensor on the rear surface of the LED substrate 10' on which the LED 11' is installed. , Transmitting antenna and receiving antenna') are installed so as not to be disturbed in transmitting or receiving high frequency. That is, the width (W1') of the LED substrate is formed to be narrower than the width (W2') of the microwave sensor module 20', and the microwave sensor module 20' has antenna units 21' configured on both sides. It is installed to be exposed to the side of the LED substrate 10'. According to this configuration, the LED substrate 10' and the microwave sensor module 20' are integrally combined, but the antenna part 21' of the microwave sensor is exposed to the outside, so that the number of LEDs 11' It is possible to provide a dimming LED lamp equipped with a microwave sensor capable of detecting the movement of the human body without reducing the value.

Here, we look at the characteristics of the microwave sensor a little more. The microwave sensor can be used in environments with poor conditions (heat, temperature, noise, moisture, airflow and dust, etc.), and there is almost no malfunction. In addition, it can detect up to 25 ~ 30m depending on the characteristics of the antenna, and can detect moving objects within 10m in diameter directly under the 360° sensing angle. In addition, since high frequency is transmitted through glass and gypsum board, there is an advantage that it can be detected even when a lamp cover is installed, and the frequency output from the microwave sensor is known to be harmless to the human body. In the case of an LED luminaire equipped with a microwave sensor module including a microwave sensor, a cover 120' through which the frequency of the microwave sensor can pass is attached to the lower portion of the LED lamp, so that the microwave sensor is not visible from the outside. Therefore, the appearance of the LED luminaire can be finished beautifully. Accordingly, there is an advantage in that the LED lighting aesthetic can be configured more stylishly.

The sensor control unit supplies driving power to the microwave sensor and outputs a signal detected by the microwave sensor as a detection signal, although not indicated by a separate symbol in the drawing. The heat sink 30 ′ absorbs and radiates heat generated from the LED substrate 10 ′, and may be made of a metal material that absorbs heat well and radiates heat. In this case, the width W3' of the heat sink 30' may be formed to be wider than the width W2' of the microwave sensor module 20'. In this case, the opening groove 31 ′ into which the microwave sensor module 20 ′ can be installed is formed. Depending on the design conditions, a heat dissipation fin (not shown in the drawing) may be formed on the rear surface that does not make contact with the LED substrate 10', so that it can be configured to dissipate heat more effectively. The heat sink 30 ′ may be omitted as long as it is received in the substrate 10 ′ and radiates heat. The control module 40 ′ outputs a dimming control signal based on a detection signal output from the microwave sensor module 20 ′, and a configuration thereof is shown in FIG. 4.

4 is a diagram illustrating a connection relationship between a configuration of a control module and a peripheral configuration in a dimming LED lamp equipped with a microwave sensor according to the present invention. According to the drawing, the control module 40' includes a detection signal receiving unit 41', a timer unit 42', a sensitivity adjusting unit 43', an illuminance sensor unit 44', and a wireless communication unit 45'. , A control unit 46' and first to third output units 47, 48, 49'. The detection signal receiver 41 ′ detects and receives a motion detected by the microwave sensor module 20 ′, and receives a signal that detects the motion in the microwave sensor module 20 ′ and outputs it as a detection signal. . The timer unit 42 ′ sets the lighting time and the time when the dimming voltage is output, and may be configured to be changeable according to a user's manipulation. Here, the lighting time means the time that the microwave sensor module 20' detects the user (human body') and outputs it as 100% of the voltage that turns on the LED, and the time that the dimming voltage is output is the user ( Human body') is not detected, and it means the time to be output as 10-20% of the voltage that turns on the LED.

Therefore, even after the lighting time and the dimming voltage output time, if the user's movement is not detected, the LED lamp remains turned off. Of course, when the user's movement is detected while the LED lamp is turned off, the LED lamp is turned on with 100% brightness. Depending on the design conditions, the time set in the timer unit 42' is the first time (100% of the output voltage) for detecting the user's motion and outputting the maximum voltage, and the second time when the user's motion is not detected (the output voltage 50%'), the third time when the user's motion is not detected (20% of the output voltage'), and the time to turn off (0% of the output voltage'), and the like. The sensitivity adjusting unit 43 ′ controls the sensing sensitivity of an object moving by the microwave sensor module 20 ′, and the sensing sensitivity may be configured to be changeable according to a user's manipulation. That is, as the sensitivity adjustment unit 43 ′ adjusts the detection sensitivity of the moving object in the microwave sensor module 20 ′, the distance from the user that the microwave sensor module 20 ′ can detect is adjusted. .

The illuminance sensor unit 44' detects illuminance around the LED lamp 1'. Based on the illuminance detected by the illuminance sensor unit 44', the control unit 46', which will be described later, may be configured to determine whether or not the LED lamp is turned on. For example, when sufficient illuminance is detected even if the LED lamp is not turned on (weekly time'), the LED lamp 1'is configured not to be turned on. Alternatively, it may be configured to dimming control the light emitted from the LED lamp 1'so that the sum of the detected illuminance and the illuminance caused by the light emitted from the LED lamp 1'reaches a set illuminance.

That is, even if motion is detected by the microwave sensor module 20', the LED lamp 1'is configured not to be turned on if there is sufficient illumination due to natural light, and the LED lamp 1'is turned on if there is insufficient natural light. It is configured to be dimmed according to the maximum required illuminance, so that it does not light up with more than necessary illuminance. The wireless communication unit 45' is for controlling lighting or dimming according to external control by wirelessly connecting to an external device. Here, the external device may include a remote-controller' and a management server. That is, the wireless communication unit 45 ′ is for controlling the LED lamp 1 ′ by wirelessly connecting the external device and the control module 40 ′, and a device capable of performing wireless communication is sufficient. The remote-controller and the management server control the on/off of the LED lamp or wirelessly control the setting time of the timer, the required illumination and the dimming rate (%, dimming voltage') when no motion is detected. Depending on the design conditions, the LED lamp 1'may be configured to be controlled as a group through an external device. For this, an individual ID (Identification') may be assigned to each control unit 46'. Accordingly, the controller 46 ′ may be provided with a memory for storing an ID and a dimming program, or may be configured separately. That is, the LED lamp 1'is configured to enable integrated control by grouping the IDs assigned to the controller 46' into a certain group unit. Accordingly, the LED lamps grouped into groups can control not only dimming control in group units, but also set conditions (timer setting time, illuminance, dimming rate') uniformly. The control unit 46' detects motion from the microwave sensor module 20' and receives an output signal output, and transmits a control signal to the dimming converter 50' for a set time according to the received detection signal.

In addition to this, a voltage suitable for the dimming unit is controlled to be output through the first output unit 47' based on the detection signal received by the detection signal receiving unit 41' and the time set in the timer unit 42'. For example, if the lighting time set in the timer unit 42' is 10 seconds and motion is detected by the microwave sensor module 20', the control unit 46' supplies the dimming converter 50' for 10 seconds. Transmits a control signal that outputs 100% voltage. In addition, if no further movement is detected during the lighting time set in the timer unit 42', the control unit applies the supply voltage to the dimming converter 50' during the time when the dimming voltage set in the timer unit 42' is output. Controls to output by %. Thereafter, if no further motion is detected after the time when the dimming voltage set in the timer unit 42' is output, the control unit cuts off the supply voltage from the dimming converter 50' to the LED substrate 10' to turn off the LED lamp. It turns off. The output voltage can be further subdivided and configured according to design conditions. That is, the output voltage may be configured to be subdivided into a voltage between 0 and 100% of the voltage supplied to the LED according to the time set in the timer unit 42 ′ and output.

In addition, it goes without saying that it may be configured to turn off the lamp when no motion is detected for a certain period of time in the dimming control lighting state. Accordingly, the first output unit 47' outputs a dimming control signal from the controller 46', and the dimming converter 50' is sent to the LED substrate 10' according to the dimming control signal output from the controller 46'. Adjust the output voltage. On the other hand, the luminaires are installed at intervals of 1 to 2m, although the intervals of the luminaires to be installed are different depending on the required illumination. However, since the microwave sensor 21 ′ can detect a moving object within 10m in diameter directly under the sensing angle of 360°, it can detect a motion in a wider range than the distance of the installed luminaire.

Accordingly, a single lamp equipped with a microwave sensor can detect and detect the motion including the dimming range of the adjacent lamp, and the adjacent lamp can also be dimmed. The second output unit 48' and the third output unit 49' output the same control signal as the control signal of the first output unit 47' output from the control unit 46' to the dimming converter 50'. This is for dimming control of LED lamps of adjacent luminaires, and is configured to perform a dimming control function of luminaires while maximizing the features of the microwave sensor module 20', thereby reducing the installation cost of lighting facilities. At this time, the second and third output units 48 and 49 ′ may be configured as connectors to facilitate connection with adjacent luminaires. Accordingly, there is an advantage that dimming control of adjacent luminaires is possible even if the microwave sensor module 20' is not provided in luminaires adjacent to luminaires equipped with lamps of the present invention. The dimming converter 50 ′ receives AC power and converts it into DC power, and dimming the LED 11 ′ of the LED substrate 10 ′ based on the control signal of the control module 40 ′. Here, the dimming converter 50' is a power line 51' for receiving commercial power, an LED driving line 52' for outputting DC power to the LED substrate 10', and power to the control module 40'. A control module driving line 53 ′ for supplying the control module and a control signal line 54 ′ receiving a control signal output from the control module 40 ′ are configured (see FIG. 2 ). This will be described with reference to FIG. 5. do. 5 shows a schematic configuration diagram according to an embodiment of another luminaire connected to a luminaire to which a dimming LED lamp is applied with a microwave sensor according to the present invention. The power line 51' of the dimming converter 50' is connected to the AC power line to receive commercial power, and the AC power is supplied from the AC/DC converter 56 (refer to FIG. 4) of the dimming converter 50'. Convert to DC power. The DC power converted by the AC/DC conversion unit 56' is adjusted to a voltage applied to the LED substrate 10' and a voltage applied to the control module 40', respectively, through the output voltage control unit 57'. , Each of the converted DC power is output through the LED driving line 52' and the control module driving line 53'.

In addition, the dimming converter 50' receives the control signal of the control module 40' through the control signal line 54' and controls the voltage applied to the LED substrate 10'. Here, the control signal line 54' is connected to the first output unit 47' of the control module 40'. The control module 40' is driven by receiving DC power from the dimming converter 50', and is output from the microwave sensor module 20'.

Outputs a control signal through the first output unit 47' based on the detected value and set information. In addition, the control module 40 ′ outputs a control signal identical to the control signal output through the first output unit 47 ′ through the second and third output units 48 and 49 ′. The control signals output through the second and third output units 48 and 49' are input as control signals of dimming converters provided in adjacent luminaires 101 and 102', and each dimming converter is applied to the input control signals. Based on this, the brightness of the LED is controlled by controlling the DC power applied to the LED substrate provided in each luminaire. In the above configuration, the first to third output units 47, 48, and 49' may be configured as connection connectors to facilitate connection with the dimming converter.

That is, the dimming control signal output through at least one of the plurality of output units is input as a control signal of a dimming converter provided in a luminaire of an adjacent LED lamp. At this time, the DC power applied to drive the control module 40' is wired so as to be supplied from one dimming converter selected from dimming converters provided in the luminaires of adjacent LED lamps. Depending on the design conditions, the luminaires 101 and 102 ′ adjacent to the left and right or front and rear of the luminaire 100 ′ equipped with the microwave sensor module 20 ′ and the control module 40 ′ are positioned to be positioned according to object detection. It may be configured to control dimming by interlocking left and right or front and rear luminaires of the luminaire 100 ′ to which the LED lamp of the present invention is controlled dimming. Here, it goes without saying that the second and third output units 48 and 49 ′ are not limited to those shown in the drawings, and may be provided in a plurality of two or more. Accordingly, since the luminaire adjacent to the luminaire to which the LED lamp according to the present invention is applied is controlled by dimming according to the control of the luminaire to which the LED lamp according to the present invention is applied, the dimming control can be performed without having a microwave sensor module in each luminaire. So the cost of the dimming equipment is reduced. However, when the included converter is not the dimming converter 50' but a general converter, the dimming control signal output from the controller 46' is meaningless. That is, the dimming control signal output from the controller 46' is effective for the dimming converter 50'. For example, a general converter converts the applied power into a power suitable for lighting an LED lamp and performs only the function of turning on/off the supply of voltage to the LED substrate 10', and delivers a dimming control signal to the general converter. Then, the general converter may determine the dimming control signal as an output voltage and output the voltage supplied to the LED substrate 10 ′ in an ON state (100% of the output voltage) to be maintained in a lit state. Accordingly, an LED lamp equipped with a general converter may be configured to transmit an ON/OFF signal to the general converter according to the user's motion detection. The 1-1th output unit 47a' is for outputting an on/off signal of the control unit 46' according to the configuration of a general converter, and will be described with reference to FIG. 5A of the accompanying drawings.

5A is a schematic configuration diagram according to an embodiment of another luminaire connected to a luminaire to which an on/off LED lamp equipped with a microwave sensor according to the present invention is applied. Here, a description of the configuration described above is omitted, and only the 1-1th output unit 47a' and the general converter 51' will be described. The 1-1 output unit 47a' outputs an ON/OFF signal according to the operation of the controller 46', and the controller 46' is an LED according to the detected signal received from the detection signal receiver 41'. An ON signal for turning on the lamp and an OFF signal for turning off the lamp are output, and the output signal is output through the 1-1th output unit 47a'. The signal output from the 1-1 output unit 47a' is transmitted to the general converter 51', and the general converter 51' is the LED substrate 10' according to the corresponding signal (on signal or off signal). The voltage applied to it is regulated. At this time, if the other luminaire to be connected is also equipped with a general converter, the output signal of the 1-1 output unit 47a' is connected to a general converter provided in the other luminaire 102' and the other luminaire 102' is also pointed. /Can be turned off. With this configuration, even if a general converter is provided, the LED lamp can be turned on/off through the general converter 51', so other lighting devices can be turned on depending on the presence or absence of the user, and the advantage of saving electric energy is have. In addition, even in the case of an LED lamp equipped with a dimming converter 50', when only the ON/OFF control is to be performed, the output signal of the 1-1 output unit 47a' is connected to the dimming converter 50'. Depending on the selection of, dimming control of LED lamps as well as on/off control can be performed. That is, the luminaires 100 and 102 ′ according to the wiring connection in FIG. 5A perform on/off control according to the user's motion detection, and the luminaire 101 ′ performs dimming control. Of course, when the output signal of the 1-1 output unit 47a' is connected to the dimming converter of the luminaire 101 ′, the luminaire 101 ′ also performs ON/OFF control. On the other hand, the dimming LED lamp control assembly provided with a microwave sensor is configured to include a microsensor module 20' and a control module 40'.

That is, the LED lamp control assembly according to the present invention receives the microsensor module 20' for detecting a moving object and outputs it as a detection signal, and the detection signal output from the microsensor module 20' according to the set information. And a control module 40' for outputting a dimming control signal. The set information may include time information such as a lighting time set in the timer unit 42 ′ and a time at which the dimming voltage is output, and illumination information detected by the luminance sensor unit 44 ′. At this time, the control module 40' is configured to drive the microwave sensor module 20' by applying the applied power to the microwave sensor module 20'. Depending on the design conditions, the LED lamp control assembly may be driven by receiving power from a separate power conversion device (eg, SMPS, etc.) or by receiving DC power output from a dimming converter of a luminaire. The control assembly configured as described above may be configured to control dimming in combination with a dimming lamp equipped with an existing dimming converter 50'.

6 and 7 are views according to an embodiment in which an LED lamp control assembly is applied using an existing LED luminaire. When a dimming converter is provided in the existing luminaire 103 ′, it may be configured to control dimming in the vicinity of the existing luminaire 103 ′ or in combination with the existing luminaire 103 ′. For example, referring to FIG. 6, the microwave sensor module 20' and the control module 40' are configured as one control assembly unit, and the driving power of the control assembly is applied from the existing luminaire 103'. Wire it so that it can be received. This and more

The selected one of the first to third outputs 47, 48, 49' of the French control module 40' is connected to the control signal line of the dimming converter provided in the existing luminaire 103'.

Similarly, in FIG. 7, the control assembly selects two outputs from the first to third outputs 47, 48, 49' of the control module 40' and controls the dimming converters of the luminaires 104 and 105', respectively. Connect with signal line. Therefore, it goes without saying that if the existing luminaire is equipped with a dimming converter, dimming can be controlled using the LED lamp control assembly of the present invention. 8 to 10 illustrate various luminaires provided with a dimming LED lamp and an LED lamp control assembly provided with a microwave sensor according to the present invention, respectively.

When described with reference to the drawings, a plurality of LEDs 11' are extended in the longitudinal direction on the LED substrate 10', and a plurality of such LED substrates 10' are installed. Among the LED substrates 10', a microwave sensor module 20' is installed on the rear surface of one LED substrate 10', and the antenna unit of the microwave sensor 21' in the microwave sensor module 20' 21') is installed so as to be exposed to the side of the LED substrate 10' so as not to interfere with transmitting high frequency or receiving reflected high frequency by the LED substrate 10'. The control module 40' is located above the microwave sensor module 20', receives a detection signal output from the microwave sensor module 20', and outputs a dimming control signal. The dimming converter 50' is attached and installed inside the luminaire 100'. The LED substrate 10', microwave sensor module 20', control module 40', and dimming converter 50' configured as described above are installed inside the housing 110' of the luminaire 100', The lower portion of the housing 110' is closed with a cover 120'. Depending on the design conditions, the LED substrate 10 ′ may be composed of a plurality of columns based on the required illuminance. In this case, the luminaire shown in FIGS. 8 and 9 is a luminaire applied to a rectangular luminaire, and in particular, the luminaire illustrated in FIG. 9 may be manufactured in a size that can replace a fluorescent lamp. Of course, it is natural that the LED lamp according to the present invention can be applied to a luminaire in which a parabolic louvers' is installed. That is, the cover 120 ′ may be composed of a parabolic louver.

10 shows an exploded state diagram of a dimming LED lamp equipped with a microwave sensor according to the present invention provided in a down light. As shown in the drawing, a plurality of LEDs 11' are installed on the installed LED substrate 10', and a microwave sensor module including a microwave sensor and a sensor control unit is provided on the rear surface of the side on which the LEDs 11' are installed. (20') is installed. At this time, the LED substrate 10 ′ may be composed of an original plate. In addition, a through hole 12 ′ is provided in the LED substrate 10 ′, and the antenna part 21 ′ of the microwave sensor is installed so as to be positioned in the through hole 12 ′, and the microwave sensor module 20 ′ is It is configured to detect and detect a moving object. Here, although not shown in the drawing, the LED substrate 10 ′ and the heat sink 30 ′ may be integrally formed, and when the heat sink 30 ′ is further provided, a groove corresponding to the through hole 12 ′ is also provided on the heat sink. Is formed. A control module 40' is provided above the microwave sensor module 20', and a dimming converter 50' is installed above it. At this time, a separation pin (not shown in the drawing) may be provided for separating the LED substrate 10 ′ and the dimming converter 50 ′ at a predetermined interval by the installed microwave sensor module 20 ′. The LED substrate 10 ′, microwave sensor module 20 ′, control module 40 ′, and dimming converter 50 ′ having this configuration are accommodated in the housing 62 ′, and a lens cover is provided on the housing 62 ′. (63') is combined. Accordingly, the LED substrate 10' and the microwave sensor module 20' are integrally combined, but the antenna part 21' of the microwave sensor is exposed to the outside, so that the number of LEDs 11' is not reduced. It is possible to provide a dimming LED lamp equipped with a microwave sensor capable of detecting moving objects while not being moved.

On the other hand, referring to FIG. 12, the microwave sensor detects a moving object (human body) using the Doppler radar principle, and the frequency reflected from the transmitting antenna transmitting the frequency and the transmitting antenna It is configured to include a receiving antenna for receiving. At this time, the frequency band mainly used is 10~20Ghz high frequency. The microwave sensor can be used in environments with poor conditions (heat, temperature, noise, humidity, airflow and dust, etc.), and there is almost no malfunction. In addition, it can detect up to 25 to 30 m depending on the characteristics of the antenna unit, and can detect moving objects within 10 m in diameter directly under the 360° sensing angle. The wavelength of the microwave sensor to be used in the present invention is in the 5.8Ghz range, which has better spreadability than 10.525Ghz, and the 10.525Ghz standard type has a section in which detection is markedly dropped, such as “A”, whereas the 5.8Ghz Pin type detects evenly overall. It can be seen that is uniformly distributed.

On the other hand, the LED lamp assembly method based on the above-described content includes the steps of preparing an LED substrate 10', a microwave sensor module 20', an on-off converter and a control module, respectively; And assembling the LED substrate 10', the microwave sensor module 20', the on-off converter and the control module, respectively. The microwave sensor module 20' includes a microwave sensor installed such that an antenna unit is exposed on the rear surface of the LED substrate 10' on which the LED is installed, and a sensor control unit for controlling the microwave sensor, and A protruding antenna part is provided. The LED substrate 10' further includes a step of inspecting through an LED substrate inspection device.

In FIGS. 16 to 18, differences between the conventional microwave sensor module and the microwave sensor module 20' of the present invention are described. The reason for using the pin type in the microwave sensor module is that the existing 10.535Ghz has a receiver and a transmitter separately, so there is a problem that it must be exposed to detect in the lighting.

In the case of LED lighting assembly example 1, if the microwave sensor is placed in the center, the center part is dark when the lighting is installed at equal intervals due to the occurrence of the dark part in the center, and the dark part in the center occurs when you look directly at it. There is a problem.

In the case of LED lighting assembly example 2, since most of the microwave sensors were assembled on one side, the effective light-emitting part was made large, thereby eliminating the dark phenomenon like a tooth dropping in the middle. However, since the 10.525Ghz standard type sensor is divided into a receiving unit and a transmitting unit, there is a problem that the recognition rate is not uniform and tends to be skewed toward one side like the antenna pattern shown in the previous page.

On the other hand, the pin type according to the present invention has the advantage of not having to expose the sensor toward the Guji light emitting surface because both the receiving unit and the transmitting unit are concentrated to a 0.8mm antenna as shown in FIGS. 16 and 18. Therefore, the effective light emitting portion of the LED lighting can be maximized, and the bezel portion is thin, so the appearance of the LED lighting has a beautiful advantage.

In addition, the 5.8Ghz pin type of the microwave sensor module 20' according to the present invention is evenly distributed in all directions at 360 degrees than the 10.525Ghz of the conventional microwave sensor module. Have.

In addition, it can be used outdoors as well as indoors in relation to the expandability of Pin type 5.8Ghz. Therefore, it has the advantage of emphasizing smarterness than the existing timer method in using group control and sensor functions for lawn lights and security lights on the side of landscape lighting.

18, the sensor is not visible when viewed from the front view, only the sensor pin is visible. From the side view, the sensor is seated on the back of the LED PCB and only the pin protrudes. This does not affect the effective light emitting part of the LED, so there is no dark part.

And, in the case of the present invention, since the sensor recognition range is wider than 10.525Ghz and has a uniform characteristic of 360 degrees, it has the advantage of not having to consider directionality. Regarding the expandability, 10.525Ghz is limited to indoors only, but 5.8Ghz is applicable for outdoor applications (eg, lawn lights, factories, security, etc.). In the present invention, it is possible to apply wired/wireless integrated group control as well as wireless bidirectional group control.

The rollers 101 may be installed inside the frame constituting the transfer unit 100 at regular intervals, and may rotate around a rotation axis to move the LED substrate 10'. Since the roller 101 is in direct contact with the lower surface of the LED substrate 10' and transfers the LED substrate 10' by rotation, it increases friction with the LED substrate 10' and prevents scratches from occurring. The surface of the roller 101 may be formed of rubber or synthetic resin. Meanwhile, according to an embodiment, the transfer unit 100 may be omitted from the LED substrate inspection apparatus 1000, and a worker may directly transfer the LED substrate 10' to the inspection table 300.

May be. The inspection table 300 mounts the LED substrate 10 ′ in a suitable inspection position. In one embodiment, the inspection table 300 may further include a fixing unit (not shown), and automatically adjust the length and width of the fixing unit according to the size of the LED substrate 10 ′, ) Can be fixedly mounted on the inspection table 300. Through this, various types and sizes of LED substrates (10') are inspected.

It can be inspected without changing the components of the station 300. In one embodiment, the inspection table 300 may further include a configuration for sensing the flow and position of the LED substrate 10 ′ and a configuration for stopping the LED substrate 10 ′. Accordingly, the inspection table 300 may detect the flow of the LED substrate 10' transferred from the transfer unit 100, and transfer and seat the LED substrate 10' at an appropriate inspection position. In addition, the inspection table 300 may rotate while forming various angles with the horizontal plane. Through this, after the photographing of the surface of the LED substrate 10' is finished, by rotating the inspection table 300, various surfaces of the LED substrate 10' such as the side or the lower surface of the LED substrate 10' can be photographed. have. For example, when performing double-sided inspection of the LED substrate 10', one side of the LED substrate 10' is photographed on the inspection table 300, and then the inspection table 300 is rotated 180° to continuously By photographing, double-sided inspection of the LED substrate 10' can be performed.

As shown, the inspection table 300 may be implemented as a flat surface, but according to the embodiment, the inner side of the inspection table 300 is inclined so that the lower surface of the LED substrate 10 ′ is the upper portion of the inspection table 300. You can prevent it from coming into contact with the surface. Through this, when the components are mounted on the lower surface of the LED substrate 10 ′, it is possible to prevent the risk of damage to the components. As shown, the inspection table 300 may seat only one LED substrate 10 ′, and a space may be formed to mount a plurality of LED substrates 10 ′. That is, the receiving space of the inspection table 300 is not limited to the number of LED substrates 10'. The moving member 400 may move the camera unit 500 in at least one of the X-axis, Y-axis, and Z-axis directions. To this end, the moving member may include a first horizontal member 401, a vertical member 402, and a second horizontal member 403. As shown in FIG. 1, the X and Y axes may be parallel to and orthogonal to the test table 300, and the Z axis may be perpendicular to the test table 300. In one embodiment, through the first horizontal member 401 and the second horizontal member 402, the camera unit 500 may be moved to the intersection of the X-axis center line and the Y-axis center line of the LED substrate 10'. . Subsequently, by moving the camera unit 500 along the Z-axis through the vertical member 402, the camera unit 500 may be positioned at an optimum focal length. Through this, the camera unit 500 can clearly photograph the entire area of the LED substrate 10 ′ with a single photographing, thereby minimizing the inspection process and improving the inspection capability. The camera unit 500 may be coupled to the moving member 400 and take a picture of the LED substrate 10 ′ seated on the inspection table 300. The camera unit 500 may include an angle adjustment unit that rotates in the direction of at least one of an X-axis and a Y-axis to adjust a photographing angle of the camera unit 500. As an example, the angle adjusting part may include an X-axis tilting part 501 and a Y-axis tilting part 502 shown in FIG. 2. Through this, the camera unit 500 can photograph the LED substrate 10 ′ at various angles, and accordingly, can photograph the side surfaces of the combined components forming a vertical angle with the LED substrate 10 ′.

In addition, according to an embodiment, the camera unit 500 may adjust the angle of the camera unit 500 according to the distance between the components coupled to the LED substrate 10 ′ at a vertical angle and the height of the components. have. The camera unit 500 generates image data of the entire LED substrate 10 ′ through a single photographing, or by changing the photographing position coordinates through the moving member 400, while changing the image data of the plurality of LED substrates 10 ′. Can be generated continuously. Image data captured by the camera unit 500 may be transmitted to the controller. The lens angle adjustment, continuous shooting, and moving shooting of the camera unit 500 will be described in detail with reference to FIGS. 2 and 3 below. The camera unit 500 is implemented as a photographing equipment having various functions and photographing ranges, as known to a person skilled in the art according to embodiments such as a charged coupled device (CCD) camera, a complementary metal oxide semiconductor (CMOS) camera, and an area scan camera. Can be. In one embodiment, the camera unit 500 may further include a lighting unit (not shown) that emits light for precise photographing of the LED substrate 10 ′. The light emitted from the lighting unit may include at least one of various lights such as white light, fluorescence, ultraviolet light, and infrared light, and appropriate light may be selected according to the characteristics of the coating material coated on the LED substrate 10 ′. The controller (not shown) may analyze the image data transmitted from the camera unit 500 to check for coating errors. The controller may determine an area in which a defect exists in the image data captured by the camera unit 500 by using a preset image data processing algorithm. For example, the control unit stores the image data of the normally coated LED substrate in advance, and then compares the image data of the LED substrate 10 ′ photographed by the camera unit 500 to the defect of the coating of the LED substrate 10 ′. You can judge whether or not. In addition, the control unit may generate the coordinates of the defect area based on the location information of the LED substrate 10 ′, and provide the defect location to the user, and control the moving member 400 and the camera unit 500 to control the defect area.

In addition, after acquiring an image of one side of the LED substrate 10 ′ by the camera unit 500, the inspection table 300 may be rotated to acquire an image of the opposite side. That is, after photographing one surface of the LED substrate 10 ′, the control unit may rotate the inspection table 300 by a set angle. By rotating the inspection table 300 by 180°, double-sided inspection of the LED substrate 10' can be performed, and the inspection table 300 can be rotated at various angles according to embodiments. In addition, in order to acquire the image data of the LED substrate 10 ′ more clearly, the control unit adjusts the X-axis and Y-axis movement of the camera unit 500 and adjusts the camera unit 500 appropriately through the moving member 400. You can move it to the focal length position. In addition, the controller may divide the LED substrate 10' into a plurality of areas to increase the clarity of the image data to be acquired according to the degree of miniaturization or integration of parts, and the camera unit 500 may be sequentially divided according to the divided areas. It can be moved to generate image data. The camera unit 500 may include an X axis tilting unit 501, a Y axis tilting unit 502, and a camera lens unit 503. The X-axis tilting part 501 is coupled to one end of the moving member 400 and can be rotated in the X-axis direction, and the Y-axis tilting part 502 is coupled to one end of the X-axis tilting part and rotated in the Y-axis direction. have.

The camera lens unit 503 may be coupled to one end of the Y-axis tilting unit 502. The camera unit 500 may variously adjust the shooting angle of the camera lens unit 503 by the X-axis tilting unit 501 and the Y-axis tilting unit 502. Accordingly, the camera unit 500 may photograph not only various surfaces of the LED substrate 10 ′, but also components coupled to the LED substrate 10 ′ at a predetermined vertical angle (eg, 90°). That is, in the prior art that can only photograph a plan view from the top of the LED substrate 10', there is a problem that it is difficult to find when the sides of the components vertically coupled to the LED substrate 10' are contaminated by the coating material. , In the present invention, by adjusting the lens angle of the camera unit 500, contamination and coating defects of the side and coupling portions of the components vertically coupled to the LED substrate 10' can be inspected, thereby providing a reliable inspection result. have. Further, by adding the movement movement of the camera unit 500 using the moving member 400 described in FIG. 3 below, the LED substrate 10 ′ and the vertically coupled components can be more precisely inspected.

As an example, the camera unit 500 measures the distance between the components coupled to the LED substrate 10' at a vertical angle and the height of the components, and then the X-axis tilting unit 501 and the Y-axis tilting By using the unit 502 to rotate the camera lens unit 503 in the X-axis or Y-axis, it is possible to adjust the shooting angle of the camera lens unit 503. The configurations of the X-axis tilting unit 501 and the Y-axis tilting unit 502 are exemplary, and the camera unit 500 according to an embodiment of the present invention includes various The configuration can be implemented with an angle adjustment unit. 3 illustrates a method of operating a camera unit according to an embodiment of the present invention. Figure 3 (a) shows a case where the distance between the components vertically coupled to the LED substrate is relatively long, and Figure 3 (b) is the distance between the components vertically coupled to the LED substrate is relatively Shows a short case. First, by rotating the camera unit 500 using the X-axis tilting unit 501 and the Y-axis tilting unit 502, the camera unit 500 forms a predetermined angle α with the LED substrate 10'. can do.

Accordingly, since the camera unit 500 can photograph the side surfaces of the components S formed perpendicular to the LED substrate 10 ′, the side portions of the components S vertically coupled to the LED substrate 10 ′ and Contamination of joints and even coating defects can be inspected. In addition, the camera unit 500 measures the distance (d), etc. between the parts (S) that form a vertical angle with the LED substrate 10 ′, and accordingly, the photographing angle of the camera lens unit 503 ( α) can also be adjusted. In addition, the camera unit 500 is a camera lens in consideration of the height of the parts S or the distance between the camera unit 500 and the LED substrate 10 ′ in addition to the distance d between the parts S. The photographing angle of the part 503 can be adjusted. As shown in (b) of FIG. 3, when the distance (d`) between the parts is relatively short compared to (a) of FIG. 3 (d>d`), the camera unit 500 is a camera lens unit 503 You can adjust the shooting angle of (α<α`). By adjusting the photographing angle, even if the parts S vertically coupled to the LED substrate 10 ′ have various intervals or heights, side image data of the parts S can be clearly photographed. In addition, the distance of the components S vertically coupled to the LED substrate 10 ′ is measured by emitting light from the camera unit 500, a method of inputting the distance between components in advance through the control unit, and the LED substrate 10 ') can be measured by various distance measuring methods known to a person skilled in the art, such as a method of applying a specific fluorescent material that can be recognized by the camera unit 500 to the joint of the parts. In addition, as shown in FIG. 3, the camera unit 500 may maintain a horizontal plane and a certain angle (α, α′), maintain a constant distance from the LED substrate 10 ′, and move in the X-axis direction. That is, while moving the camera unit 500, the LED substrate 10' fixedly mounted on the inspection table 300 may be continuously photographed. Accordingly, since the focal length of the camera lens unit 503 is kept constant, it is possible to sequentially and clearly photograph whether or not coating defects of the components S vertically coupled to the LED substrate 10'. In the case of photographing only the plan view of the conventional LED substrate 10', it was not possible to inspect whether the vertically coupled components were contaminated. In the present invention, the shooting angle of the camera lens unit 503 can be adjusted through the X-axis tilting unit 501 and the Y-axis tilting unit 502, and the camera unit 500 can be moved using the moving member 400. Therefore, this problem can be solved. In addition, as the lens is adjusted to various angles, even if the height of the combined parts S is different, the inspection may be performed by adjusting the angle. In addition, the camera unit 500 is capable of reciprocating motion, moving in the X-axis as shown, and inspecting one side of the parts S vertically coupled to the LED substrate 10', and then again Returning to the starting point, it is possible to inspect the other side of the components S vertically coupled to the LED substrate 10'. In addition, even when photographing a large-sized LED substrate 10 ′, the camera unit 500 can easily photograph the LED substrate 10 ′ through a plurality of reciprocating motions, thereby preventing additional installation of a camera or scanner. I don't need it. In one embodiment, the LED substrate 10 ′ may be divided into several areas and photographed.

Through this, the present invention can easily photograph the LED substrate 10 ′ of various sizes without changing the configuration device. Although only the X-axis movement of the camera unit 500 is illustrated in FIG. 3, the LED substrate 10 ′ may be photographed by moving the camera unit 500 in various directions such as the Y-axis direction according to an exemplary embodiment. 4 shows an LED substrate coating inspection method according to an embodiment of the present invention.

As an example, the inspection table 300 may further include a fixing part, and automatically adjust the width according to the size of the LED substrate 10 ′, thereby fixing the LED substrate 10 ′ to the inspection table 300. Through this, it is possible to inspect the LED substrate 10 ′ of various types and sizes without changing the configuration of the LED substrate inspection apparatus 1000.

Through this, image data of the clear LED substrate 10 ′ can be obtained, and even side coating errors of the components S vertically coupled to the LED substrate 10 ′ can be inspected. In an embodiment, the camera unit 500 may photograph an area of the LED substrate 10 ′ divided by the control unit using a set algorithm. Next, the LED substrate coating inspection method 400 may include a step (S450) of analyzing the captured image of the LED substrate 10 ′. That is, the controller may analyze the photographed image data to determine whether the LED substrate 10 ′ is coated with defects. In one embodiment, the control unit determines the defect area of the LED substrate 10 ′ using a preset image processing algorithm, and generates the coordinates of the defect area based on the location information of the LED substrate 10 ′ to the user.
