Diffusing layer for a light emitting apparatus

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.

An illumination assembly configured to emit diffuse light through an indicator, the assembly comprising:

• a substrate;
• an applique disposed on the substrate, the applique defining a light transmissive opening through the substrate, wherein the opening forms a negative 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, wherein each of the first portion comprises a filler material comprising a first concentration of bead structures and the second portion comprises the filler material comprising a second concentration of bead structures, wherein the first concentration transmits a different spectral distribution of light greater than the second concentration and a second light transmittance through the second portion is greater than a first light transmittance through the first portion.
