How to integrate photoluminescent material into structural parts?

Common safety glow light applications.

There are several ways to add photoluminescent properties to structural or other parts:

1. Directly add a photoluminescent compound e.g., paint or other thick liquid to the surface, possibly into a groove.
2. Attach a part with photoluminescent properties e.g., a "carrier" strip made of stiff material with photoluminescent material added, possibly into grooves.
3. Attach a solid strip of photoluminescent material e.g., a plastic strip infused with photoluminescent particles, possibly into a groove.
4. Attach a flexible strip with photoluminescent properties onto the part, possibly into a protective groove.
5. And there are other methods.

A production process:

• A production method is here publicized for depositing photoluminescent compound in liquid form to a groove specifically designed and manufactured to accept such material in structural or other part. The part does not simply act as a carrier for photoluminescent compound but is the finished product. This is case (1) above.
• A compound in liquid form can be injected into a groove by e.g., an automatically moving applicator - while the part remains stationary.
• Using a self curing/solidifying liquid compound avoids the need for elevated temperature curing. Additional various accelerators may be used.
• The grooves may have inclined walls which cave in and help keeping solid photoluminescent compound in place and increase the volume of the photoluminescent material.
• Additionally, the inclined walls keep the photoluminescent material in place regardless of the surface treatment of the [underlying] part. There is no need to use glue or other possibly hazardous product.

Designs:

A range of designs is presented with respect to ways (1) and (2) outlined above. The methods are applicable to other ways too.

A medium-size structural part.

The part shown is symmetrical. However, this does not need to be the case. The part may be L-, U-, B-, E-shaped, etc. These are simplified  designs. At left with even surface, and at right an example non-even surface:

There is no protection preventing the use of these known methods of adding photoluminescent material onto  structural or other parts, including the described production process. There exists one or more patents for manufacturing strips with metal carrier containing photoluminescent material. However, the production method presented here builds on a different premise.
Granting a patent protection requires novelty: Unpublished and/or not used anywhere before.
