Maybe it means "Донбасс"?
Donbass is a big industrial region in Ukraine.
http://en.wikipedia.org/wiki/Donbass

I can not identify a factory though.

Edit: Perhaps it is not a lighthouse but...

Would like to send picture but dont know how

NO this is not a joke. The industrial area sounds right as the design is industrial. I cannot add pictures as I dont know how!

I have some coffee cans that have донг асс written on them. Does anyone know what this means? The cans have the mark of a lighthouse on them I wonder which factory they come from. Can anyone help?
