Abstract
An optical element or a lighting element assembly including an optical element, can include a first portion of transmittance defining high transmittance enabling greater that 80% of light transmission, and a second portion of transmittance defining a low transmittance enabling less than 40% of light transmission, wherein the second portion of transmittance encircles the first portion of transmittance.
Claims18
An optical element comprising:
- a first portion of transmittance defining high transmittance enabling greater than 80% of light transmission;
- and
- a second portion of transmittance defining a low transmittance enabling less than 40% of light transmission, wherein the second portion of transmittance encircles the first portion of transmittance;
- wherein the optical element further comprises an external surface that defines a set of light altering properties at least partially defining the first portion of transmittance and at least partially defining the second portion of transmittance, and wherein the second portion of transmittance includes a spectrally neutral visual effect, enabling a concealing of the optical element.
1 more element
A lighting element assembly comprising:
- at least two illuminators spaced from each other;
- and
- an optical element associated with the at least two illuminators, and defining a respective first portion of transmittance defining high transmittance of light transmission from each associated illuminator of the at least two illuminators, and further defining a respective second portion of transmittance defining a low transmittance of light transmission from the each associated illuminator of the at least two illuminators, wherein the first portion of transmittance enables greater light transmission from the illuminator than the second portion of transmittance, and wherein each respective second portion of transmittance at least partially encircles each respective first portion of transmittance;
- wherein the second portion of transmittance defines a patterning of absorbance portions relative to non-absorbance portions.
