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.
Claims26
A light source device, 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 above the base and apart from the LED chip and having an inner surface facing towards the LED chip;
- a light shielding portion disposed on 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 at least in a region other than the light shielding portion on the inner surface of the optical member.
