White LED headlight

A light source comprising:

• at least one light emitting diode (LED) assembly, said LED assembly including a base substrate, said base substrate including base solder or stud bumps, a submount substrate mounted on the base substrate, said submount substrate including submount solder or stud bumps, and an LED semiconductor chip mounted on the submount substrate and in electrical contact with the submount solder or stud bumps, said LED semiconductor chip being electrically coupled to the base substrate through electrical vias extending through the submount substrate that are in electrical contact with the base solder or stud bumps and the submount solder or stud bumps;
• a headlight housing and a carrier being pivotally mounted to the headlight housing by an adjuster and a pivot element so as to direct the headlight in two-axis of freedom;
• and
• a flexible boot, said flexible boot being mounted to the carrier and the headlight housing so as to allow the carrier to be rotated and to maintain the seal integrity;
• wherein the light source is a vehicle light source, the light source is a vehicle headlight, and the LED assembly is sealed from the environment.

A light source comprising:

• at least one light emitting diode (LED) assembly, the LED assembly including an LED semiconductor chip and a substrate, said semiconductor chip being electrically coupled to the substrate, said LED assembly further including a molded primary optic formed over the LED assembly in contact with the substrate so that there is not an air gap between the primary optic and the LED semiconductor chip;
• a carrier, said substrate being mounted to the carrier;
• a headlight housing, said carrier being pivotally mounted to the headlight housing by an adjuster and a pivot element so as to direct the headlight in two-axis of freedom;
• and
• a flexible boot, said flexible boot being mounted to the carrier and the headlight housing so as to allow the carrier to be rotated and to maintain the seal integrity;
• wherein the light source is a vehicle headlight and the LED assembly is sealed from the environment.

A vehicle headlight comprising:

• at least one headlight unit, said at least one headlight unit including an optical structure, said at least one headlight unit further including a plurality of spaced apart primary optic lenses optically coupled to a front face of the optical structure, said at least one headlight unit further including a plurality of light emitting diode (LED) assemblies, where a single LED assembly is provided for each lens, wherein each LED assembly emits a beam of light that is focused and directed by the elongated lens and is collected and directed by the optical structure to be emitted from the front face of the optical structure as a single beam of light, wherein each LED assembly in the plurality of LED assemblies provides a portion of the intensity of the entire light pattern;
• a common carrier, the plurality of LED assemblies being mounted to said carrier;
• a headlight housing, said carrier being pivotally mounted to the headlight housing by an adjuster and a pivot element to direct the headlight in two degrees of freedom;
