good morning guys

I have a question to solve a problem for a project.

I Have a dark room (without interior lights) with more than one window, I need to enlighten with external light but without direct sunlight is in the room.

only a reflection of external light as strong as a solar day.

I attach a picture to explain better ....

ideas?

thanks
