First, referring to FIG. 13, the light source unit 150 may include a single substrate 151a, a first light emitting device group 152a ′, a second light emitting device group 152a ″, a first driving driver 153a ′, and a first substrate 151a ′. Two drive drivers 153a &quot;.

The first light emitting device group 152a ′ and the second light emitting device group 152a ″ each include a plurality of light emitting devices 152a and are disposed on the substrate 151a in the longitudinal direction of the substrate 151a. At this time, the substrate 151a is a rectangular printed circuit board, but the center portion C is electrically separated, so that the first light emitting device group 152a 'and the second light emitting device group 152a "are electrically separated. Disposed on the substrate.

The first driving driver 153a 'is disposed on the other surface of the substrate 151a on which the first light emitting device group is disposed to drive the first light emitting device group 152a', and the second driving driver 153a. &Quot;) is also disposed on the other surface of the substrate on which the second LED group is disposed to drive the second LED group 152a.

The light source unit 150 is mounted in the first and second guide grooves 202a and 202b of the single case 200, respectively, to form a lighting module.

Referring to FIG. 14, the light source unit 150 has a structure substantially the same as that of the embodiment of FIG. 13. In FIG. 14, the substrate is not only electrically separated but also physically separated to have the first substrate 151a 'and the second substrate 151a ". The rest of the light emitting device group and the driving driver are the same as those of the embodiment of FIG. Description thereof will be omitted.

As described above, the lighting module electrically separated from the light source unit can be controlled by separating and controlling the light generated from the lighting module when installed and operated on the inner wall of the room such as a wall or a ceiling, so that the degree of freedom of use can be given only to the required space. Is high. That is, as shown in FIG. 15, the lighting module divides the area A1 of the first light emitting device group and the area A2 of the second light emitting device group, and emits light by driving only the area of the first light emitting device group. Although not shown in the drawing, only the region of the second light emitting device group may be driven to perform separate driving for irradiating light. In addition, it is possible to simultaneously drive both regions of the first and second light emitting device groups.

Although only one light source unit is exemplified in this embodiment, the light source unit may have a first light source unit and a second light source unit, and each light source unit is formed in the same structure as that of forming one light source unit.

16 is a diagram for describing an operating method of a plurality of lighting modules according to an embodiment of the present invention.

Referring to FIG. 16, as shown in FIG. 11, the plurality of lighting modules 400 are mechanically and electrically coupled by the connecting member 600. As described above, each lighting module 400 may be separated and driven by electrical separation of the light source unit 150. However, in the lighting module coupled by the connecting member, the driving driver 153a 'for driving the light source unit 150 installed on both sides of the connecting member 600 forms a single. That is, instead of the plurality of driving drivers mentioned above with reference to FIG. 15, one driving driver drives the necessary portions C ′ of the two lighting modules. Since other lighting modules have already been described previously, a description thereof will be omitted.

As shown in FIG. 15, the lighting module can be separately driven by dividing a region, thereby providing a high degree of freedom in use.

Although the above description has been made with reference to the embodiments, these are merely examples and are not intended to limit the present invention. Those skilled in the art to which the present invention pertains do not depart within the scope not departing from the essential characteristics of the present embodiments. It will be appreciated that many variations and applications are possible.
