| Title: |
System and Method for Manipulating Illumination Created by an Array of Light Emitting Devices |
| Abstract: |
The present invention provides an illumination optical system that enables
the direction and mixing of light from light emitting devices. The
optical system comprises a plurality of light emitting devices that are
spatially arranged in an array, wherein this array comprises one or more
sections, such that the light emitting devices in a particular section
emit light within a predetermined wavelength range. Through the use of a
combination of macroscopic and microscopic optical systems, the
illumination created by the array can be manipulated such that a desired
illumination distribution is created. The macroscopic optical system
provides a means for redirecting the illumination in one or more desired
directions, wherein this redirection is provided by a collection of
appropriately shaped and positioned reflective optics. Subsequent to its
interaction with the macroscopic optical system, the illumination is
manipulated by a microscopic optical system that enables the diffusion of
the illumination in a predetermined manner, while retaining the desired
angular distribution of the illumination created by the macroscopic
optical system. Through the appropriate design and orientation of both
the macroscopic and microscopic optical systems, a desired illumination
effect can be created.
