Abstract
An illuminator assembly, having a plurality of LEDs on a vehicular support member in a manner such that, when all of the LEDs are energized, illumination exhibiting a first perceived hue, e.g., blue-green, and projected from at least one of the LEDs overlaps and mixes with illumination exhibiting a second perceived hue, e.g., amber, which is distinct from said first perceived hue and which is projected from at least one of the remaining LEDs in such a manner that this overlapped and mixed illumination forms a metameric white color and has sufficient intensity and color rendering qualities to be an effective illuminator.
Claims39
An illuminator assembly, comprising a plurality of LEDs disposed on a support member such that, when at least two of said LEDs are energized, illumination exhibiting a first hue having and wavelength below 505 nm and projected from at least one of said plurality of LEDs overlaps and mixes with illumination exhibiting a second hue having a do said first hue and projected from at least one of the remaining LEDs of said plurality, where said overlapped and mixed illumination forms effective metameric white illumination.
A vehicle illuminator assembly, comprising a plurality of LEDs disposed on a vehicular support member where, when said plurality of said LEDs are energized, illumination exhibiting a first hue have a dominant wavelength below 505 nm and projected from at least one of said energized plurality of LEDs overlaps and mixes with illumination exhibiting a second hue a
- distinct from said fit hue and projected from at least one of the remaining energized LEDs of said plurality, where said overlapped and mixed illumination joins effective metameric white illumination.
A vehicle maplight comprising:
- (a) housing;
- (b) a mirror element;
- and
- (c) a plurality of LEDs disposed within said housing on a support member such that when energized by a power supply illumination exhibiting a first hue having a dominant wavelength below 505 nm and projected from at least one of said plurality of LEDs overlaps and mixes with illumination exhibiting a second hue having a dominant wavelength about 530 nm, said second hue being distinct from said first hue and projected from at least one of the remaining LEDs of said plurality, where said overlapped and mixed illumination forms effective metameric white illumination.
An illuminator assembly comprising a plurality of LEDs disposed on a support member such that, when at least two of said LEDs are energized, illumination exhibiting a first hue having a peak wavelength below 505 nm and projected from at least one of said plurality of LEDs overlaps and mixes with illumination exhibiting a second hue having a peak wavelength above 530 nm, said second hue being complimentary to said first hue and projected from at least one of the remaining LEDs of said plurality, where said overlapped and mixed illumination forms effective metameric white illumination.
A vehicle illuminator, comprising a housing attached to the exterior of a vehicle, said housing having an opening adapted to receive a mirror element, said illuminator further comprising a plurality of LEDs disposed within said housing on a support member, such that when energized by a power supply, illumination exhibiting a first hue a peak wavelength below 505 nm and projected from at least one of said plurality of LEDs overlaps and mixes with illumination exhibiting a second hue having a peak wavelength above 530 nm, said second hue being distinct from said first hue and projected from at least one of the remaining LEDs of said plurality, where said overlapped and mixed illumination forms effective metameric white illumination.
