I hope I’m not too late to help you with your project. I do a lot 3D CAD work for an awning/metal canopy company. I’m on the computer 8 hours a day and I have realized I have been getting bad eye strain. I looked into it and found out that the lighting in my office had something to do with it. Unfortunately I can’t turn the lighting down because it affects my ability to see stuff on my desk. I bring this up because the idea of your lamp is to adjust the light for optimal working conditions. So if you are doing 3D modeling then the ambient light should be less then light coming from the computer screen, but then you will have a hard time seeing what is on your desk/table, likes sketches and notes. I like your idea a lot but I just see a slight flaw. Maybe you have found this in your research already.
Good luck with you project.
