That's not how lightning works. On-chain bitcoin transactions are used to open and close channels (and even then it doesn't have to be a 1-to-1 relationship), but once you have a channel open you can send funds within the channel without having to create on-chain bitcoin transactions. That's the entire point of lightning.
