1 Design flaw or im wrong?

Projector have a rather big light halo around the projected screen its more like a half moon shade on the bottom from the lens because the projected image is pointed upwards from the device and the lens is placed whitout any light block in the case

It would have been reduced if the lens had been a little further back inside or added some light block like this

try with tape. see if it makes a difference.

tried that it somewhat works but plastic inlay around the lens could be remodeled
tried black electric tape same as my example pictures
