As stated in the description, I did not know about the other map that consisted the 'light activators' while making and uploading this map.
Doesn't seem like a problem if you ask me. Plenty of 'new' test elements have been executed many times before. For instance, I wasn't the first to use world portals, and plenty of people have used anti-gravity chambers or things like that. If a concept is any good, it has almost definitely been used before.
Also, and this is not meant to hurt Jexim as Free Thought is a decent map, definitely as a first map, but he/she didn't work out the exact same element in his/her map. You seem to appreciate the inner workings of the learning curve, and that's something I can relate to. 
Having said that, it's important that you can work out nice puzzles with the concept, and make good-quality maps. That will make or break your succes, and to be honest, I think you'll do just fine. Also, still anxiously awaiting your Weightless Cubes, as I have no clue what you intend to do with them. 
TL;DR: I hope you won't get discouraged by seeing another map with this element. The same goes for other people, ofcourse. Nobody patented this, or any other element.
