How to autoload service namespace in laravel 5.6

I have created some library services in app\Library. I used AppServiceProvider to bind that service using following code:

$this->app->bind('App\Library\Globalfunction', function ($app) {
    return new Globalfunction();
});

app\Library\Globalfunction.php

<?php
namespace App\Library;

    class Globalfunction {
        protected $_ci;
        public $siteConfig=array();
        public $smtpConfig=array();
        public $socialConfig=array();

        public $paramConfig;
        public $paramFrom;

        public function test($param) {
            return $param;
        }
    }
?>

To use this test() in controller i am including namespace using following:

use App\Library\Globalfunction;

once namespace is included i use following code:

$globalFunction = new Globalfunction();
echo $globalFunction->test('hello');

All of this code working fine but i don't want to add use App\Library\Globalfunction; in each file so is there anyway i can do that? is there any autoload file where i can put this and i can access Globalfunction?

I google solution for that and i tried several solutions like add this in composer or create package etc but it's not working so please if anyone have solution for this problem please let me know.
