First Claim
Patent Images
1. An illuminated fluid level indication system for a vehicle, comprising:
- a container;
a fluid disposed in the container;
a photoluminescent portion disposed on the container; and
a light source operable to emit an emission to excite the photoluminescent portion and thereby illuminate the container,wherein a fluid level is determined based on a degree of illumination of the container when the photoluminescent portion is exposed to the emission.

Abstract
An illumination system for a vehicle container includes a fluid container, a photoluminescent portion disposed on the container, and a light source located proximate the container. The light source is configured to emit light at a first wavelength directed toward the photoluminescent portion. The photoluminescent portion is configured to convert the first wavelength to at least a second wavelength longer than the first wavelength to illuminate the container.

14. An illumination system for a vehicle container, comprising:
-
a container for holding a fluid which defines a fluid level and a headspace above the fluid; a photoluminescent portion located on the container; and a light source disposed inside the container operable to emit an emission to excite the photoluminescent portion, wherein the photoluminescent portion illuminates the container above the fluid level. - View Dependent Claims (15, 16, 17, 18, 19, 20)
