Your imagemap has the normalmap option that I just recently implemented.
Have you maybe updated BlendLuxCore without updating the LuxCore binaries?

Dade here is the test scene:
clamp.zip
(133.55 KiB) Downloaded 87 times

B.Y.O.B. i downloaded from github the BlendLuxCore master zip file it was about 9mb and i replaced the files in BlendLuxCore addon, maybe i didn't update the binaries. How can i do it?

You need to compile LuxCore.
If you don't know how to do that it's not a problem, but please use the official alpha1 download and don't update anything by hand.
Follow the procedure described here: http://wiki.luxcorerender.org/BlendLuxCore_Installation

As far as i can understand from this link https://open.gl/textures the clamp wrap in Imagemap is clamp to edge not clamp to border.

Yes. That's why I said that all border pixels have to have the color that you want to be extended.

It doesn't matter what color i want because the texture is being repeated.

B.Y.O.B. i think i understand what you are saying but if instead of a color i have a texture it's more difficult to do and not so practical.

You can set the border pixels to alpha=0 and use this node setup:
