| Title: |
Computer Controlled Light with Continuously Variable Colour Temperature, Color, Magnification, Focus and Position |
| Abstract: |
A lighting system is described having an electronic means for controlling
the color, color temperature, magnification and focus in response to
predetermined signals from a computerized system. A wide spectrum light
beam having a wavelength of from 380 nm to 700 nm is passed through a heat
absorbing condenser to control the predetermined color temperature thereof
and said portion of the beam is separated into a first color beam having a
wavelength of from 445 nm to 450 nm, a second color beam having a
wavelength of from 555 nm to 570 nm and a third color beam having a
wavelength of from 525 nm to 535 nm. The separated color beams are
maintained at substantially equal focal length an the intensity of the
respective color beams varied in response to an electronic signal. The
color beams are then combined to form a composite beam of predetermined
color. The colour and intensity of the resulting beam is thereby more
accurately predetermined.
