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.
Claims20
An apparatus for creating a consistent, stable, and high intensity oblong light comprising:
- a cylindrical lens;
- a line-light source being placed in parallel to said cylindrical lens;
- a light intensity sensor which detects light intensity of said line-light source;
- a control system which controls light intensity by adjusting power output to said line-light source based on a preset light intensity setting and feedback from said light intensity sensor;
- an enclosure having a low light reflective interior surface;
- wherein said enclosure contains said line-light source and said cylindrical lens;
- and
- wherein said line-light source's position relative to said cylindrical lens' focal line is adjustable, toward and away from said cylindrical lens, for producing parallel, converge, and diverge beams.
