אור ח׳אלן, (pronounced 'Or Kha'alan') doesn't really mean anything (and I don't care what your Hebew savvy friends told you).  However, if you were to change it to 'אור דאלן' (pronounced 'Or DaAlan'), then you would at least have the advantage of it saying 'Light of Alan' in grammatically correct Aramaic, a sister language to Hebrew.
That is simply a suggestion, which you are at perfect liberty to adopt or discard as you see fit.
