Abstract
A vehicular signal assembly that includes an inner chamber defined by a substrate comprising LED light sources and spaced apart, corresponding Fresnel lenses; and an outer chamber defined by the Fresnel lenses and an outer lens comprising optical elements. The outer lens can have a width of at least 12 mm. Further, each LED source emanates incident light directly through the chambers to produce a light pattern with a contrast ratio of 3:1 or less, e.g., a daytime running light pattern. Each LED source can also emanate incident light directly through the corresponding Fresnel lens an outer lens to produce the daytime running light pattern.
Claims20
A vehicular signal assembly, comprising:
- an inner chamber defined by a substrate and spaced apart, corresponding Fresnel lenses;
- and
- an outer chamber defined by the lenses and an outer lens,
- the chambers non-linearly shaped, and
- the substrate comprises a plurality of LED sources emanating light through the chambers into a light pattern with a contrast ratio of 3:1 or less.
A vehicular signal assembly, comprising:
- an inner chamber defined by a substrate and spaced apart, corresponding Fresnel lenses;
- and
- an outer chamber defined by the lenses and an outer lens,
- the chambers having a substantially open construction, and
- the substrate comprises a plurality of LED sources emanating light through the chambers into a light pattern, each LED source emanating light through the corresponding lens and at least one adjacent lens.
