Light guide assembly for a lighting system of an aerosol-generating system and method of manufacture thereof

A light guide assembly for a lighting system of an aerosol-generating system, the light guide assembly comprising:

• a support structure comprising a light transmissive body, the light transmissive body being configured to channel light therethrough towards a surface of the light transmissive body;
• and
• an opaque coating or film overlying a surface of the light transmissive body, the opaque coating or film comprising a plurality of apertures configured for transmission therethrough of light channeled through the light transmissive body,
• wherein the support structure further comprises an opaque body,
• wherein the light transmissive body comprises a first set of one or more light transmissive portions and a second set of one or more light transmissive portions,
• wherein the opaque body and the light transmissive portions are configured to interconnect with each other such that the opaque body separates the first set of one or more light transmissive portions from the second set of one or more light transmissive portions, and
• wherein the second set of one or more light transmissive portions is arranged to partially or wholly surround the first set of one or more light transmissive portions.

A method of fabricating a light guide assembly, the method comprising:

• providing a support structure comprising a light transmissive body and an opaque body, the light transmissive body being configured to channel light therethrough towards a surface of the light transmissive body, wherein the light transmissive body comprises a first set of one or more light transmissive portions and a second set of one or more light transmissive portions;
• interconnecting the opaque body and the light transmissive portions with each other such that the opaque body separates the first set of one or more light transmissive portions from the second set of one or more light transmissive portions and the second set of one or more light transmissive portions partially or wholly surround the first set of one or more light transmissive portions;
• applying a coating or film of opaque material to a surface of the light transmissive body;
• and
• selectively removing portions of the opaque material from the coating or film to define a plurality of apertures through the coating or film for transmission therethrough of light channeled through the light transmissive body.
