| Title: |
Illumination Device For Simulating Neon Lighting Through Use of Fluorescent Dyes |
| Abstract: |
An illumination device simulates neon lighting and allows for emission of
light in colors that cannot ordinarily be achieved by use of LEDs alone
through the incorporation of a light color conversion system into the
illumination device. This light color conversion system comprises an
intermediate light-transmitting medium tinted with a predetermined
combination of one or more fluorescent dyes. Light emitted from the light
source of the illumination device is directed into the intermediate
light-transmitting medium and interacts with the fluorescent dyes
contained therein. This light is partially absorbed by each of the
fluorescent dyes of the intermediate light-transmitting medium, and a
lower-energy light is then emitted from each of the fluorescent dyes and
into the light-receiving surface of the waveguide. Thus, selection of
appropriate combinations of dyes results in various colors being emitted
from the illumination device.
