How switch a specific expression to lower case in a file (linux command)

I'm trying to find a command or to create a script on linux allowing to switch a specific expression to lower-case in many files in subdirectories.

I need this to change the case in all the includes statements in a C++ project (Porting Visual studio project to linux)

So in many files I have

#include <Path1/pAth2/naMeofTheHeader.h>

and i would like to change it to 

#include <Path1/pAth2/nameoftheheader.h>

(Of course I don't want the path to be moved in lower case)

Does anyone have an idea to perform this? I tried somme sed command (with \L) but anything have worked.

Thanks

You could try the below sed command,

sed 's~\(#include .*\/\)\([^\/.]*\)~\1\L\2~g' file

Example:

$ echo '#include <Path1/pAth2/naMeofTheHeader.h>' | sed 's~\(#include .*\/\)\([^\/.]*\)~\1\L\2~g'
#include <Path1/pAth2/nameoftheheader.h>
