Faking reflection of lamp emission

Hello.
I create interior visualizations and render with eevee.
To reduce the computational load, we wanted to reflect the reflection of the lamp light source inside the lighting shade without using a point light.
This is useful when the lamp light source is not in the viewport and screen space reflection does not work.
Let’s reproduce this with a shader node.


Screenshot of how the node was constructed.

Set the vertex color to affect only the inside of the lighting shade.
