Diffusing layer for a light emitting apparatus
First Claim
1. An illumination assembly configured to emit diffuse light through an indicator, the assembly comprising:
- a substrate;
an applique disposed on the substrate forming an opening, wherein the opening defines a shape configured to transmit light through the substrate;
a light source in connection with a circuit and configured to emit light through the shape; and
a diffusing layer comprising a first portion and a second portion applied to a surface of the assembly between the circuit and the substrate, the diffusing layer comprising;
a resin material; and
a filler material comprising a plurality of bead structures configured to diffuse light from the light source, wherein the first portion comprises a first concentration of the bead structures and the second portion comprises a second concentration of the bead structures and the first concentration provides for a different spectral distribution of light than the second concentration.

Abstract
An illumination assembly configured to emit diffuse light through an indicator is disclosed. The assembly comprises a substrate having an applique disposed thereon. The applique forms an opening configured to transmit light through the substrate. The assembly further comprises a light source in connection with a circuit and configured to emit light through the shape. A diffusing layer is applied to a surface of the assembly between the circuit and the substrate. The diffusing layer comprises a resin material configured to cure in response to exposure to ultraviolet light or heat. The diffusing layer further comprises a filler material comprising a plurality of beaded structures configured to diffuse light from the light source.

9. A method for manufacturing an illumination assembly comprising a diffuse light indicator comprising the steps of:
-
preparing a substrate corresponding to a display surface to receive a coating; applying an applique on the substrate thereby forming an opening, wherein the opening defines a shape of the diffuse light indicator; applying a first liquid diffusing layer over the applique, the liquid diffusing layer comprising a resin material and a filler material having a first concentration of bead structures; applying a second liquid diffusing layer over the applique, the second liquid diffusing layer comprising a resin material and a filler material having a second concentration of bead structures, wherein the first concentration provides for a different spectral distribution of light than the second concentration and a second light transmittance through the second liquid diffusing layer is greater than a first light transmittance through the first liquid diffusing layer; attaching a circuit comprising at least one light source to the substrate enclosing the applique and the diffusing layer therebetween; and curing the liquid diffusing layer thereby generating a hardened diffusing layer laminating the substrate to the circuit. - View Dependent Claims (10, 11, 12, 13, 14)
