Abstract:
The invention teaches a new method to provide lighting for photography and other purposes. A consistent, stable, high intensity line-light source is created by using a cylindrical lens and a line-light source using feedback control. The positioning of the line-light source is adjustable to produce parallel, convergence, and divergence beams depending on the desired lighting characteristics. The invention also teaches a new apparatus using the current invention.
