Abstract
Official abstract text for this publication.
A light assembly for attachment to a surface of a vehicle includes a vehicle base configured to be coupled to the surface of the vehicle, and a light head coupled to the vehicle base and including a plurality of light emitting diodes and a lens. The lens has a plurality of total internal reflection lenses. Each total internal reflection lens has a truncated frustoconical cross-sectional shape.
First claim
Opening claim text (preview).
What is claimed is: 1. A light assembly for attachment to a surface of a vehicle, the light assembly comprising: a vehicle base configured to be coupled to the surface of the vehicle; and a light head coupled to the vehicle base and including a plurality of light emitting diodes and a lens, the lens having a plurality of total internal reflection lenses, wherein each total internal reflection lens has a truncated frustoconical cross-sectional shape. 2. The light assembly of claim 1 , wherein the plurality of total internal reflection lenses is arranged in an array of rows. 3. The light assembly of claim 2 , wherein the plurality of total internal reflection lenses is arranged in an array of columns. 4. The light assembly of claim 1 , wherein the lens includes a lens piece having the plurality of total internal reflection lenses. 5. The light assembly of claim 4 , wherein the lens piece has a flat, outward-facing face, and wherein each of the total internal reflection lenses is arranged as part of a face opposite the outward-facing face. 6. The light assembly of claim 4 , wherein each of the total internal reflection lenses is integrally molded as part of the lens piece. 7. The light assembly of claim 4 , wherein each of the total internal reflection lenses is separately formed. 8. The light assembly of claim 4 , wherein the light head includes a PCB supporting the plurality of light emitting diodes, and a reflector arranged between the PCB and the lens piece. 9. The light assembly of claim 8 , wherein the reflector includes a plurality of cups having a truncated frustoconical shape, each cup mated with one of the plurality of total internal reflection lenses. 10. The light assembly of claim 9 , wherein each cup has an aperture to accommodate one of the plurality of light emitting diodes, and wherein each total internal reflection lens has an aperture, and wherein the aperture of each cup is aligned with the aperture of the total internal reflection lens to which it is mated. 11. The light assembly of claim 8 , wherein the plurality of light emitting diodes includes a plurality of flood light-light emitting diodes and a plurality of spot light-light emitting diodes, and wherein the reflector includes a plurality of cups with apertures to accommodate the spot light-light emitting diodes and a plurality of pockets including apertures, and wherein the aperture of each pocket is configured to allow a passage of light from one of the plurality of flood light-light emitting diodes.
