Abstract
A headlight for a vehicle includes a light source. The light source includes: a substrate; a light emitting diode chip; and a phosphor. The phosphor through which light exiting from a light emitting surface penetrates. The phosphor includes an exiting surface through which the light from the light emitting surface penetrates and exits. A first direction of the exiting surface corresponds to a height direction of a light distribution pattern by the light exiting from the exiting surface, and a second direction of the exiting surface corresponds to a spread in a lateral direction of the light distribution pattern. A dimension in the first direction of the exiting surface is smaller than a dimension in the second direction of the exiting surface.
Claims6
A headlight for a vehicle, the headlight comprising
- a light source, the light source including:
- a substrate;
- a light emitting diode chip disposed on the substrate;
- and a phosphor disposed on a light emitting surface of the light emitting diode chip, the phosphor through which light exiting from the light emitting surface penetrates,
- the single light emitting diode chip being disposed on the single substrate,
- the phosphor including an exiting surface through which a light from the light emitting surface penetrates and exits,
- a first direction of the exiting surface corresponding to a height direction of a light distribution pattern by the light exiting from the exiting surface,
- a second direction of the exiting surface corresponding to a spread in a lateral direction of the light distribution pattern,
- the second direction of the exiting surface being perpendicular to the first direction of the exiting surface,
- a dimension in the first direction of the exiting surface being smaller than a dimension in the second direction of the exiting surface.
