The present invention relates to a lighting device. The lighting device according to an embodiment of the present invention includes: a light source emitting light; and a reflection unit which reflects the light to collect the light on a target area. The traveling path of the light passing through the light source, reflection unit, and target area is always constant regardless of the location of the light source. As the light source is spaced further apart from the target area, the light source becomes closer to the reflection unit. |
