A lighting module according to an embodiment includes at least two light source parts which generate light, at least two upper light guides which guide light generated from each of the light sources to a light axis (Ax), a lower light guide which condenses light guided by the upper light guides and guides it to the light axis (Ax), and a diffuser which is arranged in the upper light guide, diffuses light emitted from the light source part, and shields the light source part. The cross section of the upper light guide and the lower light guide is gradually extended as the upper light guide and the lower light guide approach the light axis. The extension level of the cross section of the lower light guide is larger than that of the upper light guide. |
