Best Mode for Carrying Out the Invention Hereinafter, a configuration and an operation of a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a configuration diagram of an LED light system according to the present invention. Referring to FIG. 1, the LED light system includes a plurality of LEDs 100, an assembly substrate 200 on which the LEDs 100 are assembled, A transparent case 400 for protecting the plurality of LEDs 100, the assembly substrate 200, and the PCB 300 and the transparent case 400 for protecting the plurality of LEDs 100, the PCB 300, A first illuminance sensor 500 attached to the inside of the transparent case 400 to measure the illuminance of light emitted from the plurality of LEDs 100 to generate a first measured value, A second illuminance sensor 600 for measuring the illuminance of the LED 100 to generate a first measured value, and a second illuminance sensor 600 electrically connected to the PCB 300 to measure a minute current generated in the LED 100, A circuit breaker 700 for isolating the LED 300 from the PCB 300, And a first transmitter 800 receiving the first measured value and the second measured value measured by the second illuminance sensor 600 and transmitting the received second measured value to the external controller.

More specifically, the plurality of LEDs 100 refer to light emitting diodes, which are well known or known in the art and will not be described in further detail herein.

A plurality of LEDs 100 inserted into the holes are formed in the assembly substrate 200 so that the plurality of LEDs 100 are inserted into the holes and the LEDs 100 are electrically and electronically connected to the PCB 300 .

The PCB 300 is electrically / electronically connected to an LED inserted through a plurality of holes formed in the assembly board 200, and collects information on a plurality of LEDs 100.

The information on the plurality of LEDs 100 is power information for determining the power supply state for each of the LEDs, and determines whether the LEDs 100 are short-circuited by the power supply information. At this time, when the PCB 300 is short-circuited, the first transmission unit 800 transmits the short-circuit information indicating that the LED is short-circuited together with the position information that the PCB inherently possesses to the first transmission unit 800, To the server (900) which controls it.

In addition, the first illuminance sensor 500 may collect a first measured value of the illuminance of the light emitted from the LED, and the second illuminance sensor 600 may measure a second illuminance of the external light (sunlight) And transmits the collected values to the first transmission unit 800.

The transparent case 400 is variously configured to protect the plurality of LEDs 100, the assembly substrate 200, and the PCB 300, and the light emitted by the plurality of LEDs 100 A transparent material is preferable. That is, it is preferable that the lamp is manufactured in various forms such as a shape suitable for a stand for a stand, and a shape suitable for a street lamp for a street light.

The first illuminance sensor 500 is designed in one place within the transparent case 400. The first illuminance sensor 500 measures the illuminance of the light emitted by the LED in a predetermined time interval, The measured values are transmitted to the server 900 through the first transmission unit 800.

The second illuminance sensor 600 is designed in one place outside the transparent case 400. The second illuminance sensor 600 measures a second measured value obtained by measuring the illuminance of the external light for each set time period, To the server (900).

The breaker 700 is electrically connected to the PCB 300 to measure a minute current generated from the plurality of LEDs and automatically cut off the power when the current is more than a preset constant current.

This is to prevent a safety accident that may be caused by a microcurrent. Since a lot of moisture is generated in a climatic characteristic, for example, a rainy season, and the microcurrent flows outside the lamp, a dangerous situation may occur. ), And acts to shut it off.

In addition, it is preferable that the circuit breaker (700) is automatically shut off when the current is below the minimum current or the maximum current, and the circuit breaker (00) is further provided to prevent a short circuit.

The first transmission unit 800 receives the LED information or short circuit information from the PCB 300 and the position information specific to the PCB 300 and outputs the first measurement value measured by the first roughness sensor 500 and the second roughness And receives the second measurement value measured by the sensor 600 and transmits it to the external equipment.

The external equipment is preferably a server 900. The server 900 includes a receiving unit 910, a DB 920, a controller 930, and a second transmitting unit 940 as shown in FIG.

In more detail, the receiver 910 receives the delimiter information, the position information, the first measured value, and the second measured value from the first transmitter 800 and outputs the received delimiter information, the positional information, the first measured value, And controls the plurality of LEDs 100 using the second measured value.

The DB 920 stores a first reference value for determining whether the first measured value received by the receiving unit 910 is a normal measured value or an abnormal operation of the LED, A second reference value for determining whether the second measured value is abnormally operated is a measurement value for normally operating the LED.

The first reference value and the second reference value are extracted by the controller 930 when the first measured value and the second measured value are received, thereby allowing the administrator to check the status of the LED lamp.

When receiving the delimiter information, the controller 930 includes information indicating that the LED is short-circuited among the plurality of LEDs in the delimiter information, and the positional information is transmitted together with the delimiter information. Therefore, It can be determined that the LED is faulty.

The position information and the paragraph information are displayed on the display to guide the manager to easily check the LED lamp.

When the first measured value is received, the first measured value is compared with the first reference value stored in the DB 920. If the first measured value is larger than the first reference value, the normalized value is displayed normally. If the first measured value is smaller than the first reference value Mark abnormally.

That is, since the first measured value is a value obtained by measuring the illuminance of the LED, having a value larger than the illuminance of the first reference value means that the LED operates normally.

Next, when the second measurement value is received, the second measurement value is compared with the second reference value stored in the DB 920. If the second measurement value is greater than the second reference value, the power supply is kept in the OFF state, If it is smaller than the reference value 2, keep the power ON.

That is, since the second measured value is the measurement of the external light (sunlight), the second measured value is larger than the second reference value, which means that the external light is larger. Therefore, since the LED bulb does not need to operate, 2 means that the measured value is smaller than the second reference value, which means that the light emitted from the LED is larger, which means that the external light is dark, so that the LED bulb is controlled to be turned on so as to be continuously operated.

The second transmitting unit 940 may be configured to receive information about the LED lamp including the shorted LED, information on a result of comparing the first measured value with the first reference value, compare the second measured value with the second reference value, And transmits information about the result to the manager client or the manager terminal.

The means for transmitting to the manager client or the manager terminal corresponds to a well-known technique or a well-known technique, and a detailed description thereof will be omitted.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to cover further limitations anddisclamping the scope of the present invention as defined by the appended claims. It is not.
