Abstract
The present application discloses a LED-based solar simulator light source having at least one LED array formed by multiple LED groups of LED assemblies, at least one field flattening device, at least one diffractive element, and at least one optical element configured to condition the broad spectrum light source output signal and direct the light source output signal to a work surface.
Claims34
A LED-based solar simulator light source, comprising:
- at least one LED array formed by multiple LED groups of LED assemblies, each LED group configured to output at least one optical signal within a discrete spectral range;
- at least one field flattening device configured to flatten at least one optical characteristic of the multiple outputs from the LED groups forming the LED array;
- at least one diffractive element configured to receive and combine the optical signals from the multiple LED groups to produce a broad spectrum light source output signal;
- at least one optical element configured to condition the broad spectrum light source output signal and direct the light source output signal to a work surface;
- and
- at least two alignment devices positioned on the LED light source, the alignment devices configured to output at least two alignment signals from the LED light source to the work surface at an angle wherein the alignment signals intersect on the work surface when the LED light source is located at a desired height from the work surface.

A LED-based solar simulator light system, comprising:
- at least one LED-based light source having at least one LED array positioned therein, the LED array formed by multiple LED groups of LED assemblies, each LED group configured to output at least one optical signal within a discrete spectral range, wherein the multiple LED groups cooperatively output at least one light source output signal having a wavelength spectra;
- at least one control device in communication with LED-based light source and configured to selectively control the output of at least one LED group thereby permitting selective variation of the wavelength spectra of the light source output signal;
- and
- at least two alignment devices positioned on the LED light source, the alignment devices configured to output at least two alignment signal from the LED light source to the work surface at an angle wherein the alignment signals intersect on the work surface when the LED light source is located at a desired height from the work surface.
