color White is equal to rgb <1,1,1>

You have to turn transparency of background with option passed in command
line. This is described in manual in subchapter named "Output File Type". If
there would be anything you still do not understand, feel free to ask.

BTW: please use something useful for the subject in the future. Thanks in
advance.

  Transparent background is not specified in the scene file but in
the command-line options, using the option +ua (ie. "use alpha").
This can be written in the command-line text field in the windows
version or a proper .ini file (or if you are using a command-line
version of POV-Ray, then of course right in the command line).

  Note that in order for POV-Ray to be able to save the alpha channel
to the image file, you have to use a format which supports alpha channel,
such as for example PNG.

Yes I'm sorry I have forgotten the subject.
I have read the "output_file_type" it looks like difficult. Where I have to
put this, in the background? "background { ??? }" I only want a transparent
background not configure my graphic target.

Mentioned subchapter is enclosed in chapter about POV-Ray options. Those
options can be located in command line when POV-Ray is launched and/or in
ini-file readed prior parsing/rendering your scene and/or in platform specific
place like command-line in toolbar in Windows port.

Try to browse manual, this is way to wide subject to be explained in simple
post.

I do not know what do you mean as "graphic target", but you cannot have
transparent background if you do not have transparency/aplha support in file
format you are rendering into.

"You may turn this option on with Output_Alpha=on or +UA. The default is off
or -UA."
I don't understand where I have to activate it.
=====================================
background { White }
  camera {location <170, -11, -110>look_at  <180, -15, -16>}
  light_source { <170, -30, -100> color White}
=====================================
I'm sorry.

Not in your .pov file. I assume you're running POV-Ray for Windows, in which
the correct place to put "+UA" is the textbox next to the drop down on the
upper left of the program. This should also be to the left of the "POV-Win"
toolbar button.
