A parabolic reflector is utilized for a vehicle head lamp having a housing, lens, light emitting diodes and control circuits for the light emitting diodes. The parabolic reflector comprises a plurality of reflective panels in an upper array for the low beam and a lower array for the high beam. The upper array is formed by three rows of twelve panels in side-to-side configuration. The lower array is divide into two separate groups, with each group having a two outermost panels, two intermediate panels and two innermost panels. The reflective panels of the upper array and the lower array are so positioned with respect to the light emitting diodes as to form a desired luminous intensity distribution from the head lamp.

A light assembly for a vehicle includes quantum dots that are excitable by sources of electromagnetic radiation. The assembly may include a lens and a reflector, and the quantum dots may be disposed adjacent the reflector and/or in the lens. A controller may receive a signal to produce a particular color and activate one or more source of electromagnetic radiation, and one or more subsets of the quantum dots may be excited in response to activating the particular source of electromagnetic radiation. The assembly may include a panel having quantum dots embedded therein. The panel may be illuminated by the quantum dots in response to activating one or more source of electromagnetic radiation. The panel may have different zones with different quantum dots that produces distinct areas with different colors. The sources of electromagnetic radiation may be activated separately to produce different colors or simultaneously to produce a blended color.

Improved light emitting diode (LED) vehicle headlamps having a dedicated daytime running lamp (DRL) component are described. In various embodiments, a combination Low Beam/DRL headlamp is provided, which uses pulse width modulation (PWM) detection to determine which of the two internal LED light sources (Low Beam or DRL) is powered on. If the Low Beam/DRL headlamp detects a PWM signal on the Low Beam voltage input then it switches to drive the DRL LEDs. If, alternatively, it detects a steady state input voltage then it switches to drive the Low Beam LEDs.

A lamp for a vehicle includes an array module including a plurality of micro Light Emitting Diode (LED) chips. The array module includes a plurality of regions, where each region includes one or more arrays. Each array includes at least a portion of the plurality of micro LED chips. At least one of the plurality of regions includes arrays that are stacked to each other, where a number of arrays stacked at a first region among the plurality of regions is different from a number of arrays stacked in a second region among the plurality of regions.
