If you just want the list you can do basically the same thing you do
from the CLI.

ls $log_year"-"$log_month"-"$log_day"--*.zip

If you want to act on each file individually then maybe a loop.

Assuming your script is running in the same directory as the files
something like this maybe?

for f in $log_year"-"$log_month"-"$log_day"--*.zip; do
  // do whatever you want with $f here
done
