Model naming in Codeigniter

[cossay]

If I have a model called Admin_user which extends CI_Model, how do I name the file in which this model class is so that codeigniter can load it?
I named the file admin_user.php and placed it in application/models directory but Codeigniter does not load the class when I try loading the model like
$this->load->model('admin_user');

Am not familiar with CI but my guess is that the case should match.

admin_user <> Admin_user

In case you want to use a different name, it can also be used an alias:

$this->load->model('Model_name', 'admin_user');
$this->admin_user->something();
