Laser-based fiber-coupled white light system for a vehicle

A laser-based-fiber-coupled white light illumination source for a vehicle, the fiber-coupled white light illumination source comprising:

• a package configured to emit a white light emission, the package comprising:
• a laser device comprising a gallium and nitrogen containing material and configured as an excitation source, the laser device comprising an output facet configured to output a laser emission with a first wavelength ranging from 385 nm to 495 nm;
• a phosphor member configured as a wavelength converter and an emitter and disposed to convert the laser emission to emit an electromagnetic radiation with a second wavelength longer than the first wavelength, the electromagnetic radiation is combined with the laser emission partially to generate the white light emission of at least 800 lumens;
• a support member configured to support the laser device and the phosphor member;
• a transparent lid member coupled to the support member and configured to allow the white light emission to pass through the transparent lid member;
• an optical member mounted on the transparent lid member and configured to receive the white light emission passing through the transparent lid member and to focus the white light emission to provide a focused white light emission;
• a fiber having a diameter of less than 2 mm configured to couple the focused white light emission from the optical member with at least 20% coupling efficiency and deliver the focused white light emission, wherein the fiber also is at least partially configured as a leaky fiber to scatter light partially out of fiber body arranged in a custom shape at a feature location;
• and
• a cover extending around external edges of the package and coupled to a periphery of the optical member and to a first end portion of the fiber, wherein the first end portion of the fiber extends through a first aperture of the cover and the package is arranged in a second aperture of the cover so that a bottom portion of the package is exposed outside the cover.

A fiber-coupled white light illumination source for vehicle lighting applications comprising:

• a package having a transparent lid member for emitting a white light, the package comprising:
• a laser module electrically coupled to a vehicle power system, the laser module comprising a gallium and nitrogen containing laser chip and a driver receiving power from the vehicle power system to drive the laser chip to output a laser emission with a first wavelength ranging from 385 nm to 495 nm;
• a white light module comprising a phosphor member coupled with the laser module, the phosphor member being configured as a wavelength converter and an emitter to receive the laser emission at a primary surface of the phosphor member, the phosphor member configured to convert the laser emission to a phosphor radiation with a second wavelength longer than the first wavelength and to combine the phosphor radiation with the laser emission partially to generate the white light, the white light characterized by an emission of at least 300 lumens;
• an optical member mounted on the transparent lid member of the package and configured to receive the white light from the primary surface of the phosphor member and to focus the white light to provide a focused white light;
• a transport fiber having a diameter of 1 mm or less configured to couple the focused white light from the optical member with at least 20% coupling efficiency;
• and
• a cover extending around external edges of the package and coupled to a periphery of the optical member and to a first end portion of the transport fiber, wherein the first end portion of the transport fiber extends through a first aperture of the cover and the package is arranged in a second aperture of the cover so that a bottom portion of the package is exposed outside the cover;
• wherein the transport fiber is arranged to deliver light to an exterior or interior feature location of a vehicle;
• and
• wherein the feature location of the vehicle includes at least one of a headlight, front grill structure, license plate, lower and side bumper, dashboard, door handle and panel, entry sill, window frame, ceiling, moonroof, floor, or seat.
