A mood lamp may include a light source disposed at one side, a light guide panel transmitting and guiding light emitted from the light source to a front side, and a surface member disposed over a front surface of the light guide panel and having apertures for passing the light transmitted and guided by the light guide panel to the front side. The light guide panel may include optic protrusions formed on a rear surface of the light guide panel at locations corresponding to the apertures of the surface member and reflecting the light traveling through the light guide panel to the apertures. The light reflected by the optic protrusions is transmitted through the apertures of the surface member.
