Claims

[Scope of Claim for Utility Model Registration] (1) A reflecting mirror having a reflecting surface that reflects light from a light source placed at a focal point and condensing the light onto a condensing section in front; A vehicle headlamp comprising: two light sources disposed slightly apart from each other; and a concave lens disposed closer to the reflecting mirror than the condenser. (2) Two light sources extend along the optical axis of the reflective surface,
Registration of a utility model characterized in that one of the light sources is located approximately at the focal point, the other is located slightly in front of one of the light sources, and the front and lower half of the other light source are covered by a light-shielding cap. A vehicle headlamp according to claim 1. (3) A vehicle headlamp according to claim 1 or 2, characterized in that a large number of light control elements are formed on a concave lens. (4) A request for registration of a utility model characterized in that a concave lens has a large number of light control elements formed thereon and a curved surface is formed on the light control element so that it functions as a concave lens. A vehicle headlamp according to item 1 or 2. (5) A vehicle headlamp according to claim 1, wherein a control lens having a large number of light control elements is disposed in front of the concave lens.
