Multi-piece light guide for enhanced alignment through an opaque surface

An accessory device suitable for carrying an electronic device, the accessory device comprising:

• a bottom wall comprising an opening, the bottom wall defining a receiving surface for the electronic device;
• sidewalls that extend from and surround the bottom wall, wherein the sidewalls and the bottom wall define a receptacle for the electronic device;
• a battery separated from the receptacle by the bottom wall;
• a first light source and a second light source, the first light source providing light to indicate a first charging state of the battery, the second light source providing light to indicate a second charging state of the battery, the second charging state different from the first charging state;
• and
• a light guide assembly positioned between the bottom wall and the first and second light sources, the light guide assembly comprising:
• a light guide body having a light receiving surface that receives the light from at least one of the first light source and the second light source, the light guide body comprising a cavity aligned with the opening, and
• a light guide insert positioned in the cavity carried by the light guide body and aligned with the opening, the light guide insert comprising a light emission surface, wherein the light guide insert is configured to receive the light from the light guide body and diffuse the light across the light emission surface, thereby causing the light to pass through the opening and away from the bottom wall, wherein the light guide assembly is covered by the electronic device when the electronic device is positioned in the receptacle.

A method for assembling a light guide assembly in an accessory device having an opaque layer, the method comprising:

• identifying a location of a light guide body hidden by the opaque layer, the light guide body positioned between the opaque layer and a light source, wherein sidewalls extend from the opaque layer and define a receptacle for an electronic device, wherein a connector extends from a sidewall of the sidewalls to electrically couple the electronic device to a battery carried by the accessory device, and wherein the light guide body comprises a first portion and a second portion different from the first portion;
• after identifying the light guide body, performing a single cutting operation that forms a through hole in the opaque layer and a cavity in the light guide body such that the cavity is concentric with the through hole;
• and
• inserting a light guide insert in the cavity, the light guide insert optically coupled with the light guide body and comprising a light emission surface, wherein the light guide insert is configured to receive the light from the light guide body and pass the light across the light emission surface, wherein light rays from a light source in the accessory device are reflected from the second portion converge at the first portion.
