1. A light source device configured to emit light in a light emitting direction and along an optical axis, comprising:
- a base having an upper surface and a cavity located at the upper surface;
an LED chip located adjacent the cavity of the base;
a resin portion located adjacent the LED chip;
an optical member disposed adjacent the upper surface of the base and separate from the LED chip and having an inner surface facing towards the LED chip;
a light shielding portion disposed adjacent the inner surface of the optical member and configured to form a cutoff suited for a light distribution pattern; and
a fluorescent substance layer disposed adjacent the inner surface of the optical member and at least in a region other than the light shielding portion when the device is viewed from the light emitting direction.

Abstract
A light source for vehicles can include a base having a cavity formed on its upper surface, an LED chip mounted in the cavity of the base, a resin portion for sealing the LED chip in the cavity, an optical member disposed above the base and apart from the LED chip, a light shielding portion disposed on the inner surface of the optical member and which forms a cutoff suited for a light distribution pattern, and a fluorescent substance layer disposed at least in regions other than the light shielding portion on the inner surface of the optical member.

22. A light source device configured to emit light in a light emitting direction and along an optical axis, comprising:
-
a base having an upper surface and a cavity located at the upper surface; an LED chip located adjacent the cavity of the base; a light shielding portion disposed adjacent the LED chip and configured to form a cutoff suited for a light distribution pattern, an inner surface of the light shielding portion including a reflection surface configured to reflect light emitted from the LED chip, wherein the reflection surface is disposed at an angle with respect to the optical axis so as to reflect light received from the LED chip at an angle with respect to the optical axis, and the base includes a base reflection portion that is located and positioned to receive light that is reflected by the reflection surface of the light shielding portion from the LED chip towards the light emitting direction of the device. - View Dependent Claims (23, 24, 25, 26)
