As mentioned by @tsl143 the function plugins_url() is what you want, along with the __FILE__ magic constant. If you call it from a file inside your plugin folder it will refer to that folder.

Example:

For the directory:

echo plugins_url( '' , __FILE__ ); 
//outputs: http://www.example.com/wp-content/plugins/my-plugin    

For a file or subdirectory in your plugin directory:

echo plugins_url( 'images/logo.png' , __FILE__ ); 
//outputs: http://www.example.com/wp-content/plugins/my-plugin/images/logo.png
