In particular, the PCB may be composed of a flexible printed circuit board (FPCB (FPCB), hereinafter referred to as FPCB) to facilitate power transfer.

In general, FPCB is an electronic component developed by miniaturization and light weight of electronic products. It is excellent in workability, strong in heat resistance and chemical resistance, and resistant to heat, so it is a core component of all electronic products such as cameras, computers, peripherals, and portable devices. It is widely used in terminals, video and audio equipment, printers, camcorders, TFT LCDs, satellite equipment, military equipment, and medical equipment.

The FPCB can be three-dimensional wiring alone, and the device can be made smaller and lighter. In addition, the FPCB is capable of high-durability high-density wiring to repeated bending, has no merit of wiring, good assembly, and high reliability. In other words, when there is a moving part, the existing cable has a weakness of weakness because the cable is broken when moving several times, FPCB can solve this problem.

FPCB is divided into single-sided structure, double-sided structure and multi-structure according to its structure. The cross-sectional structure is the most basic structure and is used for cable connecting connectors and sub boards of electronic products. The double-sided structure is a type in which copper foils are formed on both sides of the base film and is used when the number of patterns cannot be arranged in a limited area due to the miniaturization and light weight of electronic products. The multi-structure is a four-layer or more structure developed in response to the market demand of the current high-performance mobile phone from the simple function puller-type mobile phone.

The present invention proposes a method of using the power transfer member 200 for transferring power to the light source 110 by using the advantages of the FPCB. According to FIG. 2, the light source 110 has one power transmission member 200 composed of FPCBs, but the light source 110 may have a power transmission member 200 composed of at least two FPCBs according to a manufacturing process. . In this way, power can be transmitted in various directions. By supplying power to the light source using the FPCB as described above, it is possible to arrange the light source in various ways as compared with the conventional socket-type power supply. In addition, even when the space is narrow, it is possible to smoothly supply power due to the characteristics of the FPCB having flexibility.

The power transmission member 200 may deliver power to the light source by attaching or detaching the slot 310. Desorption and attachment of the power transmission member 200 are performed by inserting or removing the power transmission member 200 into the slot 310. This insertion or removal has the advantage that it can be easily performed compared to the conventional power connection method. In addition, the power transmission member 200 has an advantage that the power can be provided using another adjacent slot when the power is not smoothly supplied from the slot 310 is currently coupled.

The controller 320 controls the power provided by the light source. For example, the controller 320 controls the power provided to the light source according to a switch or other manipulation of the user. Alternatively, when the controller 320 is set to supply power from the first time to the second time, the controller 320 automatically supplies power to the light source at the first time, and cuts off the power automatically supplied at the second time. .

In addition, the controller 320 may control to provide power to only some of the plurality of light sources. That is, the controller 320 controls the first light source to supply power for the second time from the first time, and the second light source controls to supply power for the fourth time from the third time, and the third light source includes the first light source. It is possible to control to supply power from the second time to the third time.

This will be described in addition as follows. The controller 320 may directly control the power supplied to the power transmission members 200 coupled to the slot 310. In addition, the power transmission member 200 is coupled in the form of pushing into the slot 310, or separated in the form of pulling. The user can simply stop the power supply in the form of pulling the power transmission member 200 connected to the light source to stop the power supply to the slot 310. In addition, the user can simply resume the power supply by pushing the power transmission member 200 connected to the light source to resume the power supply to the slot 310.

 In addition, when the slots 310 are configured in an array form as illustrated in FIG. 3, the user may control power in units of arrays. To this end, the power supply member 300 may configure a switch in an array unit. For example, the slots located at the top of the power supply member 300 are coupled to the first switch, and the slots located at the bottom of the power supply member are coupled to the second switch.

The user can control the light source supplied with power from the slot located at the top by controlling the power supplied to the slots located at the top of the power supply member 300 using the first switch. The user may control the light source to receive power from the slot located at the bottom by controlling the power supplied to the slots located at the bottom of the power supply member 300 using the second switch. Of course, the first switch or the second switch can be controlled using the control unit 320, it can be controlled manually by the user.

In addition, the power supply member 300 may configure the switch in various forms, it is possible to control the power supplied to the light source using the configured switch. That is, the switch may be configured in each slot unit, or the switch may be configured in each slot located at a predetermined interval unit. Of course, as described above, the controller 320 may control the power supplied directly to the slot without using a switch.

As described above, the controller 320 may control power supplied to the plurality of light sources in various ways. Hereinafter, the light source supported by the support member will be described.

The light source supported by the support member may be composed of LED lighting or OLED lighting or hybrid lighting combining LED lighting and OLED lighting.

Control the operation of 110-5 to 110-8).

That is, the light sources 110-1 to 110-4 located at the top of the plurality of light sources and the light sources 110-5 to 110-8 positioned at the bottom of the plurality of light sources are illustrated in FIG. Unlike the light source control), the control is performed using the two controllers 320-1 and 320-2.

In detail, the first controller 320-1 may control the light sources at the upper end to be turned on for the first time, and the second controller 320-2 may control the light sources at the lower end to be turned on for the second time. . As such, the plurality of light sources 110-1 to 110-8 are grouped and controlled by a unique controller for each group, thereby improving control efficiency of the light sources. In addition, by controlling the light source using the two control units in this way, the load on the control unit can be reduced.
