The embodiment can slide in the longitudinal direction with the second light source unit inserted into the first light source unit so that the length of the entire light source of the lighting apparatus can be adjusted. Accordingly, it is possible to provide a flexible lighting environment in various environments.

The embodiment has a simple structure and is easy to manufacture, and the number of the light source units can be adjusted to realize light sources of various lengths.

Specifically, the first light source module 130 is positioned on the upper surface 111 of the first case 110 and emits light toward the lower surface 112 of the first case 110. At this time, as described above, light emitted from the first light source module 130 is transmitted through the lower surface 112 of the first case 110.

The first light source module 130 has a size corresponding to the upper surface 111 of the first case 110 and may be arranged to cover the entire upper surface 111 of the first case 110. In this case, in the folded state of the lighting apparatus 10, the light emitted from the first light source module 130 is blocked by the second light source module 230. Specifically, the support substrate 132 of the first light source module 130 is formed to correspond to the upper surface 111 of the first case 110.

The second case 210 has a shape corresponding to that of the first case 110 and is sized to be accommodated in the first case 110. However, when the second case 210 is drawn into the first case 110, the first light source module 130 is positioned outside the second case 210.

The second case 210 is slid along the longitudinal direction of the first case 110 while being inserted into the first case 110 through the opening 114 of the first case 110.

The second case 210 may be made of a material having high strength so that the internal parts can be protected from external impacts. For example, the second case 210 may include any one of a metal, a metal alloy, and a synthetic resin material.

As another example, the lower surface 212 of the second case 210 may include a plurality of optical sheets for converting light incident on the second light source module 230 into surface light. A detailed description thereof will be described later.

As another example, the lower surface 212 of the second case 210 is made of a transparent material through which light is transmitted. Accordingly, the light supplied from the first light source unit 100 is emitted to the outside through the lower surface 212 of the second case 210.

A guide groove 219 is formed on an outer surface of the second case 210 to provide a space for sliding the guide protrusion 119. [ The guide groove 219 guides the guide protrusion 119 when the second case 210 is slid. The guide groove 219 is elongated in the longitudinal direction of the second case 210 or the longitudinal direction of the first case 110. Specifically, the pair of guide grooves 219 are provided on the left and right sides of the second case 210.

In the embodiment, the connection terminal 218 is provided to receive the driving power from the power module 16 located in the first case 110. The connection terminal 218 is electrically connected to the second light source module 230 and is formed long on the outer surface of the second case 210 in the longitudinal direction. The connection terminal 218 provides a place where the supply terminal 118 is slid and connected when the second case 210 is slid. The connection terminals 218 are exposed to the outer surface of the second case 210 or protrude from the outer surface of the second case 210.

The connection terminal 218 has electrical conductivity. The connecting terminal 218 may be made of a metal material, for example, titanium (Ti), copper (Cu), or the like.

The second light source module 230 is accommodated in the second case 210. The second light source module 230 is disposed long in the longitudinal direction of the second case 210. Specifically, the second light source module 230 is positioned on the upper surface of the second case 210 and emits light toward the lower surface 212 of the second case 210. At this time, as described above, light emitted from the second light source module 230 is transmitted through the lower surface 212 of the second case 210. Of course, the lower surface 212 of the second case 210 may be provided with diffusion particles for converting the light into the surface light.

The second light source module 230 may have a size corresponding to the upper surface of the second case 210 and may be disposed to cover the entire upper surface of the second case 210. Of course, as will be described later, the second light source module 230 may be disposed in a part of the upper surface of the second case 210. [

Accordingly, it is possible to provide a flexible lighting environment in various environments.

FIG. 7 is a sectional view of a folded state of the lighting apparatus according to another embodiment of the present invention, and FIG. 8 is a plan view of the expanded state of the lighting apparatus shown in FIG.

Referring to FIGS. 7 and 8, in the lighting apparatus 10 according to another embodiment, there is a difference in the arrangement of the light source modules as compared with the embodiment in FIG.

When the first light source module 130 and the second light source module 230 are vertically overlapped with each other, the light emitted from the first light source module 130 in the folded state of the illuminator 10 ), So that optical loss is generated.

Accordingly, the second light source module 230 is disposed at a position that does not vertically overlap with the first light source module 130. In this case, since the lights of the first light source module 130 and the first light source module 130 are both downwardly provided in the folded state of the lighting apparatus 10, there is an advantage of no light loss. Also, the first light source module 130 and the second light source module 230 provide light having a longer length in the longitudinal direction of the illuminating device 10.

More specifically, the upper surface 111 of the first case 110 is divided into a first area S1 and a second area S2 along the width direction of the first case 110, The upper surface 211 of the first region S2 is divided into a third region S3 vertically overlapping the first region S1 and a fourth region S4 vertically overlapping the second region S2.

The first light source module 130 is located in the first region S1 and the second light source module 230 is located in the fourth region S4 so that they do not overlap with each other. In this case, the third region S3 of the second case 210 is formed in such a manner that the light emitted from the first light source module 130 is transmitted And is preferably made of a transparent material.
