primary information for antminer L3 ++ can be help me, it information?
Are you looking for specific information on this ASIC?
There is no L3++ and there is only the L3+. You can easily find the specs and other information directly from the bitmain website: bitmain.com
There is also a lot of dicussion on the L3+ here in the forums. Please just use the search bar.
That's wrong, their current model is called L3++:

Though the L3++ is said to be a bit less overclockable than the original L3+. I remember reading that Bitmain said that the L3++ is slightly improved L3+ but most think the L3++ is not as good as older L3+.
The discussion thread for L3+ / L3++ can be found here:
