1. A lighting apparatus comprising a first light source module and a second light source module, which are spaced a predetermined distance apart from each other, wherein the first light source module comprises:
- a first light guide member configured to guide a first light emitted from a first light source; and
a first emission layer, which is formed on the first light guide member and in which the first light from the first light source is used as excited light, and the first emission layer to provide a third light having a different wavelength than the first light, andwherein the second light source module comprises;
a second light guide member configured to guide a portion of the third light from the first emission layer and a second light emitted from a second light source; and
a second emission layer, which is formed on the second light guide member and in which the third light that is provided from the first emission layer and the second light from the second light source are used as excited light, and the second emission layer to provide a fourth light having a different wavelength than the third light from the first emission layer and the second light from the second light source, wherein the fourth light from the second emission layer is to have a stereoscopic effect.

Abstract
Provided are a lighting apparatus that is capable of implementing various stereoscopic effects and a lamp for a vehicle including the lighting apparatus. A volumic type, a depth effect, and a stereoscopic effect of optical patterns emitted after an interaction of excited light of emission layers disposed in adjacent light source modules can be implemented so that various designs of three-dimensional (3D) light can be implemented.
