The present invention provides a lamp comprising: a half mirror having a top surface and a bottom surface, reflecting a portion of light incident onto the bottom surface, and emitting another portion of the light to the outside; a reflective layer disposed at the lower side of the half mirror and disposed to face the bottom surface of the half mirror; an electrochromic layer disposed between the half mirror and the reflective layer and disposed to cover the reflective layer; a light source unit emitting light between the half mirror and the reflective layer; and a control unit applying a current or a voltage to the electrochromic layer, wherein the electrochromic layer has a variable light transmittance as the current or voltage is applied thereto.
