Find database given physical file name

I was looking for ways to clean up my server disk space. One of them by shrinking sql server log file. I found a log file that was quite big. Unfortunately, there was no database name that has similar name with the physical file. I would not check physical name of each database one by one by issuing sp_helpdb command as my server hold tens databases. I would rather run script to find exactly what database hold this file.
Here is what I get:
SELECT
DB_NAME(database_id) database_name,
physical_name
FROM master.sys.master_files
where physical_name ='physicalfilename'
