Referring to FIG. 9, the lighting device kit according to the present embodiment may include a converter 110, an electric wire 113, or a cable, a base substrate 120, a light emitting device 130, and a lens 140. .

The converter (110 in FIG. 9A) is an AC / DC converter for converting AC power into DC power, and converts a high voltage AC power of 100V or more, such as 110V or 220V, to a low voltage DC power of 75V or less, for example, 15V to 75V. do. In particular, the converter 110 may convert an AC power of 100V or more into a DC power of 40V or more, and by converting the DC power of a relatively high voltage, the size of the converter 110 may be reduced, and the converter 110 may also be used. You can save money. In addition, by converting to a DC power supply of 75V or less, users can safely assemble the lighting device without considering an electric shock. The converter 110 may have a connection groove 111 for connecting the wire 113.

Meanwhile, the wire 113 (in FIG. 9B) is for inputting power output from the converter 110 to the light emitting device 130, and has a structure in which the inner conductor 112 is covered with an insulator 114. The wire 113 may be provided in pairs with two conductive wires 112 to be connected to the positive terminal and the negative terminal.

In general, wires (cables) connected to household AC power supply are relatively thick for stability and reliability because they carry high voltage AC current. However, in the present embodiment, since the home AC power is converted into a DC power of 75V or less by the converter 110, the wire 113 that is relatively thin as compared with the conventional wire is the converter 110 and the light emitting device 130.

Alternatively, connectors (eg, see 55b in FIG. 2) for coupling the wires 113 to each other are provided at both ends of the wires 113, and the wires 113 can be interconnected using these connectors. have. Therefore, according to the distance between the converter 110 and the light emitting device 130, a plurality of wires 113 may be coupled to each other to form an elongated wire.

Therefore, in use, the electric wire 113 can be easily attached to a wall or the floor using a double-sided tape. Alternatively, the wire 113 may be attached to the wall or the floor using a general tape or the like, or the wire 113 may be inserted into a groove formed on the wall or the bottom to fix the wire 113.

Alternatively, the base substrate 120 may be temporarily fixed to the floor, the ceiling, or the wall of the room by using an adhesive tape or the like.

Meanwhile, in other embodiments, the wire 113 may be directly connected to the light emitting device 130. In this case, the base substrate 120 only serves to support the light emitting device 130, and thus the electrical connector 121 or the electrical terminals 123 may be omitted. Furthermore, the base substrate 120 may be omitted.
