Since the LED device operates as a DC power source, the LED power source includes a power source for converting the AC power source to the DC power source. The LED power source controls the DC power source for controlling the plurality of LED devices to be turned on, off, dimming, A control unit may also be provided as an electronic circuit. The power supply unit includes a transformer and a rectifying circuit, and the control unit includes a current control circuit and the like. These power supply units and the control unit are usually implemented on one substrate, and the substrate is collectively referred to as a converter or a controller.

In recent years, LED lighting has been widely used in the field of technology represented by the Internet of things, for example, it can control the lighting in the house from outside the house through a mobile device such as a smart phone, or automatically lights according to the amount of natural light, Or the emergency situation of the health of the occupant can be notified to the outside, the function is expanding day by day.

These functions are mainly implemented by the control unit in the converter. The more the converter having many functions, the more the manufacturing cost increases, and the user has to pay for the unnecessary functions in the viewpoint of the user. In addition, the lifetime of the power source, which is a relatively high-voltage and high-voltage circuit, tends to be shorter than the lifetime of the low-voltage and low-voltage control unit. There is a burden.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a control board and a control board assembly for a functionally expandable LED lighting according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an embodiment of a control board for functionally-extending LED lighting according to the present invention, and FIG. 2 is a perspective view illustrating a state in which a communication module and a sensor module are coupled to the embodiment of FIG.

The control board 100 for functionally-extended LED lighting according to the present invention comprises a PCB board 110 and performs at least one of control for turning on, off, or dimming the LED on the PCB board 110 A control circuit 120 is formed. The elements and the wirings constituting the control circuit 120 can be implemented in various forms according to ordinary circuit design techniques, but they are common in that they are DC circuits in any form.

The power and signal connector 130 is installed at the edge of the PCB substrate 110. The power and signal connector 130 receives the power required for the operation of the control board 100 and provides power and signals for operating the external LED. The power and signal connector 130 is a so-called board-to-board connector for direct connection to a connector installed on another board. Here, the power and signal connector 130 is a board-to-board connector, which means that the control board 100 can be directly coupled to another board without the need for a cable. In this regard, Which is advantageous compared with the conventional method. As an example of a board-to-board connector, FIGS. 1 and 2 illustrate that the power and signal connector 130 is in the form of a pin header connector. However, it should be appreciated that the power and signal connectors 130 may be replaced by other types of connectors, such as edge connectors, as long as they can function as a board-to-board connector.

The power and signal connector 130 is for receiving DC power, because the control board 100 does not include a transformer or rectifier circuit. That is, as described above, the control board 100 is formed by transforming and rectifying the AC power through another external substrate or device such as the power board 200, which will be separately described below, And only the function of controlling the operation of the LED with the DC power supply is included. Compared with the control circuit 120 included in the control board 100, the circuit for transforming or rectifying is a relatively high-heat and high-voltage circuit, and thus has a short life span. Therefore, it is advantageous to configure the control board 100 according to the present invention separately from circuits for these transforming or rectifying operations.

The communication port 140 is detachably coupled to the communication module 20. Here, the communication module 20 is for exchanging data with other external devices according to a control signal of the control board 100. [ 1 and 2 illustrate that the communication port 140 is a USB port. In this case, the communication module 20 may be a USB port such as a wifi dongle, a bluetooth dongle, a zigbee dongle, A commercial wireless communication device having an interface can be selectively used. Of course, the communication port 140 may be another type of port such as RS-232C or RJ-45, and the communication module 20 may be a wired communication device. In this case, It is necessary to have a connector conforming to the format of the USB 140, so it may be relatively difficult for the general user to receive the USB dongle as compared with the commercial USB dongle. When the communication module 20 is connected, the control circuit 120 can control the LED through communication with an external device. For example, when the communication module 20 is a Bluetooth dongle, when the smart phone is connected to a smartphone and transmits a signal for controlling lighting and lighting of the LED in the smartphone, the LED can be controlled accordingly. Conversely, the current control state of the control circuit 120 may be transmitted to an external device through the communication module 20 so that the current state of the LED can be confirmed by an external device.

The sensor port 150 is detachably coupled to the sensor module 30. The sensor module 30 includes at least one sensor capable of detecting an external environment required for controlling LED light such as a temperature sensor, an infrared sensor, an illuminance sensor, and an operation sensor. When the sensor module 30 is provided, the control circuit 120 can control the LED illumination according to the type of the sensor module 30. [ For example, when the sensor module 30 includes an illuminance sensor, the control circuit 120 may control the LED lighting to be automatically turned on if the illuminance of the room is less than a predetermined value. If the sensor module 30 includes the operation sensor, The LED light may be turned on when the movement of the LED is detected. If the temperature sensor is provided, it is determined that a fire has occurred when the room temperature is higher than a predetermined temperature, so that the LED illumination can be turned on or the outside of the fire can be notified through the communication module 20 described above.

The plurality of communication ports 140 and the sensor port 150 may be provided according to the number of required communication modules and sensor modules.

FIG. 3 is an exploded perspective view of an embodiment of a control board assembly for a functionally expandable LED illumination according to the present invention, and FIG. 4 is an assembled perspective view of the embodiment of FIG.

The control board assembly for functionally-extended LED lighting according to the present invention includes the control board 100 for the functionally-extended LED lighting described above and a housing 50 for housing the control board 100.

The housing 50 is joined with the upper plate 51 and the lower plate 52 to form an inner space, and forms an appearance of the control board assembly according to the present invention. The housing 50 is provided with a connection board 400 having a connection connector 410 for receiving the power supply of the control board 100 and the signal connector 130. The control board 100 is connected to the housing 50, As shown in FIG. The housing 50 also receives the control board 100 and is attached to the LED lighting fixture, which also protects the control board 100 from the external environment. It is preferable that the communication port 140 and the sensor port 150 of the control board 100 are exposed to the outside of the housing 50 so that the communication module 20 or the sensor module 30 can be easily attached and detached. For this purpose, a through hole 53 is formed in the housing 50. 3, the through holes 53 are formed in the upper plate 51 of the housing 50. However, the through holes 53 may be formed in the lower plate 52 depending on the partitioning type of the housing 50 or the shape of the upper plate 51 and the lower plate 52 . Thus, the communication module 20 or the sensor module 30 can be easily attached and detached without opening or separating the housing 50.

Meanwhile, the inner space of the housing 50 may be divided into at least two spaces using the partition 60 or the like. In this case, the control board 100 is accommodated in one of the divided spaces, and the power board 200 is accommodated in the other. The power board 200 includes a transformer and a rectifier circuit not included in the control board 100. The power board 200 receives AC power from the outside and converts it into DC power and outputs the DC power to the control board 100. That is, the power supply board 200 corresponds to the AD-DC converter. Since the power supply board 200 is a high heat and high voltage circuit compared to the control board 100, the influence of the power board 200 on the control board 100 can be suppressed by disposing the power board 200 in the different space of the housing 50 separately from the control board 100 . The power board 200 is electrically connected to the control board 100 and may be directly connected to each other through the power supply of the control board 100 and the signal connector 130. As illustrated in Figure 3, Or may be connected via a separate connection board 400 having a connection terminal 410.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
