Compared to the lighting case according to the first embodiment of the present invention shown in FIG. 1, the lighting case according to the second embodiment of the present invention shown in FIG. is the same Hereinafter, the unidirectional light exit member 110'' will be described in detail with reference to FIG. 6 .

FIG. 6 is cross-sectional views of the unidirectional light exit member 110'' shown in FIG. 5 . 6(a) is an example of a cross-sectional view of the unidirectional light exit member 110″ shown in FIG. 5, and FIG. 6(b) is a cross-sectional view of the unidirectional light exit member 110″ shown in FIG. Another example.

Referring to (a) of FIG. 6, the unidirectional light emitting member 100'' according to an example includes a buried layer 119a or a unidirectional light emitting member 110 shown in FIGS. / and a protective layer (119b) is further included.

The filling layer 119a is disposed on at least one portion of one surface 112 to fill the cavities 115 formed in the one portion.

The filling layer 119a may be a UV curable resin. Alternatively, the buried layer 119a may be made of the same material as the light emitting member 110'' or a material having the same or similar refractive index to that of the light emitting member 110''. Here, the refractive index of the buried layer 119a may be 0.8 to 1.2 times the refractive index of the light exit member 110''. Outside the numerical range, total reflection is not performed well due to a difference in refractive index from the light exit member 110''.

The buried layer 119a may be formed on a portion of one surface 112 through a printer nozzle. Here, the filling layer 119a may be formed to cover a portion of one surface 112, as shown in (a) of FIG. ) may be filled to form a portion of one surface 112 flat.

The printer nozzle may be a component included in a UV inkjet printer. The UV inkjet printer may control the printer nozzle to drive it in a predetermined direction, and may output resin inside the printer nozzle to the outside at a specific position according to the control. The buried layer 119a may be formed only on a portion of one surface 112 of the light emitting member 110 by the UV inkjet printer. Thereafter, the buried layer 119a may be hardened through a hardening process. In (a) of FIG. 6, the buried layer 119a is formed only on one part of one surface 112 of the light exit member 110, but this is an example, and another one or a plurality of parts of one surface 112 A buried layer 119a may be formed thereon. By forming another one or more buried layers 119a, a specific shape or logo shown in (b) and (c) of FIG. 5 can be formed on one surface 112 of the unidirectional light exit member 110. .

The filling layer 119a may be formed by various methods as well as the inkjet printing method, and may be patterned by, for example, a stencil or silk screen printing method.

The deformable portion 119c may be a portion in which the cavity 115 formed on at least one portion of the surface 112 is deformed by heat having a glass transition temperature or higher applied from the outside and is flattened or flattened. In fact, the plastic type recovers to flatten when heated after the intaglio pattern is engraved.

A heating member such as a heating element probe may be used to form the deformable portion 119c. If some cavities 115 are heated with the heating element probe and directly pressed, or if some cavities 115 are heated in a predetermined direction with the heating element probe, the deformable portion 119c may be formed. Meanwhile, the heating member may be a hot air nozzle emitting hot air.

A heating device having a heating element probe or a hot air nozzle may drive the heating element probe or the hot air nozzle according to a control command. For example, the heating element probe or the hot air nozzle may be moved in a specific direction, the temperature of the heating element probe may be controlled, or the amount of hot air discharged from the hot air nozzle may be controlled.

At least a portion of the deformable portion 119c is flat, but at least another portion may have a partially gently convex or gently concave shape. In the deformable portion 119c, as shown in (a) of FIG. 6, light incident from a light source is not transmitted and almost all of the light is totally reflected.
