No... I will point out that pyramids and prisms of light where significant in many cultures. A pretty bit of imagery is not 'illuminati' because it contains such culturally significant elements.
Illumanati, root word Illuminate. It is common to say that one who is in the know, is enlightened. Light, illuminate. Therefor, anyone who is enlightened, is also known as illumanati. The term is often associated with being evil, but it is far from that when you do your homework.
