Abstract
Official abstract text for this publication.
In order to provide a vehicular headlight in which a rise in temperature of an extension member due to sunlight can be suppressed, and for which the appearance can be improved, a vehicular headlight includes: a light source; a reflector that reflects light from the light source; a lens having an entry surface through which light reflected by the reflector enters, and an exit surface from which the light that has entered the entry surface exits into an irradiation region in front of the vehicle; an extension member disposed at least in front of and below the lens in a vehicle-mounted state, and including a colored portion and a light-transmitting member that is disposed covering the colored portion and is capable of transmitting light; and a light-scattering portion provided at least in a portion of the light-transmitting member below the lens in the vehicle-mounted state.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicular headlight, including: a light source; a reflector that reflects light from the light source; a lens having an entry surface through which the light reflected by the reflector enters, and an exit surface from which the light that has entered the entry surface exits into an irradiation region in front of the vehicle; and an extension member disposed at least in front of a lower end of the lens in a vehicle-mounted state, wherein the extension member includes: a light-transmitting member that has a plate shape, that is provided with a first surface facing forward in the vehicle-mounted state and a second surface on an opposite side to the first surface, and that is capable of transmitting light from the first surface to the second surface, a colored portion disposed on the second surface of the light-transmitting member, and a light-scattering portion provided in a position in the light-transmitting member at which sunlight focuses as a result of internal reflection in the lens in the vehicle-mounted state. 2. The vehicular headlight according to claim 1 , wherein the light-scattering portion is disposed on the first surface of the light-transmitting member. 3. The vehicular headlight according to claim 1 , wherein the light-scattering portion is disposed in the light-transmitting member on an inner side, in a horizontal direction, of the vehicle in the vehicle-mounted state. 4. The vehicular headlight according to claim 1 , wherein the extension member is disposed so as to surround an outer periphery of the lens. 5. The vehicular headlight according to claim 1 , wherein the colored portion is black.
