Abstract
An illuminating device for a vehicle head lamp which defines a clear cut line of light distribution pattern. The light from a light source is transmitted through an optical fibre and is incident to a light conducting path lens from the optical fibre in a predetermined pattern defined by a shade. The light conducting path lens condenses and irradiates at an outgoing plane the light from a light incident plane. Thus, light distribution pattern is defined by the shape of the shade and the optical characteristics of the light conducting path lens. An end section of the shade defines an upper cut line, particularly at an opposite lane side, of the light distribution pattern. The shade is provided coincidentally with an optical axis of the outgoing plane of the light conducting path lens. Thus, the upper cut line of the light distribution pattern at the side of the opposite lane side is defined clearly and, hence, a wide illuminating range extending to the opposite lane can be provided without causing glare to drivers of vehicles on the opposite lane.
