wherein the light guide plate is configured to emit the light from the light source through a top surface and a bottom surface of the light guide plate,
wherein the bottom surface of the light guide plate comprises a projection, and
wherein the case comprises a receiving recess into which the projection is inserted.
2. The lighting module of claim 1 , wherein the light guide plate includes a plurality of the patterns disposed within the light guide plate.
3. The lighting module of claim 2 , wherein the plurality of the patterns comprises at least one of a circular shape, an elliptical shape and a slot shape.
4. The lighting module of claim 2 , wherein the plurality of the patterns are disposed closer to at least one of the top and the bottom surfaces of the light guide plate.
5. The lighting module of claim 2 , wherein a density of the plurality of the patterns becomes greater toward a central portion of the light guide plate from the both sides of the light guide plate.
6. The lighting module of claim 1 , wherein the light guide plate includes a plurality of the patterns disposed on at least one of the top and the bottom surfaces of the light guide plate.
7. The lighting module of claim 1 , further comprising:
a phosphor luminescent film disposed between the light guide plate and the light source.
8. The lighting module of claim 1 , further comprising:
a diffuser plate disposed on at least one of the top and bottom surfaces of the light guide plate.
9. A lighting module comprising:
a light guide plate including a top surface and a bottom surface, both of which are configured to emit light;
a case covering one side of the light guide plate;
a light source which is disposed in the case and includes a substrate and a light emitting device disposed on the substrate,
wherein the one side of the light guide plate is disposed on a portion of the light emitting device, and
wherein the case comprises an upper case and a lower case, and the lower case comprises a base on which the substrate is disposed and an extension part which extends from the base and supports one side of the substrate and the bottom surface of the light guide plate; and
an adhesive sheet disposed between the bottom surface of the light guide plate and the extension part of the lower case.
10. The lighting module of claim 9 ,
wherein the upper case comprises a base on which the base of the lower case is disposed and an extension part which extends from the base of the upper case and supports the other side of the substrate and the top surface of the light guide plate.
11. The lighting module of claim 9 , wherein the bottom surface of the light guide plate comprises a projection, and wherein the lower case comprises a receiving recess into which the projection is inserted.
12. The lighting module of claim 9 , wherein the light guide plate comprises a plurality of patterns, and wherein the plurality of the patterns are disposed within the light guide plate.
13. The lighting module of claim 12 , wherein the plurality of the patterns comprises at least one of a circular shape, an elliptical shape and a slot shape.
14. The lighting module of claim 12 , wherein the plurality of the patterns are disposed closer to at least one of the top and/or and the bottom surfaces of the light guide plate.
15. The lighting module of claim 12 , wherein a density of the plurality of the patterns becomes greater toward a central portion of the light guide plate from both sides of the light guide plate.
16. The lighting module of claim 9 , wherein the light guide plate comprises a plurality of patterns formed on at least one of the top and the bottom surfaces of the light guide plate.
17. The lighting module of claim 16 , wherein a density of the patterns becomes greater toward a central portion of the light guide plate from both sides of the light guide plate.
18. The lighting module of claim 9 , further comprising:
a phosphor luminescent film disposed between the light guide plate and the light source.
19. The lighting module of claim 9 , further comprising:
a diffuser plate disposed on at least one of the top and the bottom surfaces of the light guide plate.
20. A lighting module, comprising:
a light guide plate including a predetermined pattern;
a case covering both sides of the light guide plate; and
a light source which is disposed in the case and is configured to emit light to the both sides of the light guide plate,
wherein the light guide plate is configured to emit the light from the light source through a top surface and a bottom surface of the light guide plate,
wherein the lighting module is configured to emit first light upward from the top surface of the light guide plate, and second light downward from the bottom surface of the light guide plate, and
wherein an amount of the first light is different from an amount the second light.
