Abstract
Light-emitting diode (LED) packages, and more particularly broad electromagnetic spectrum LED packages are disclosed. Individual LED packages are disclosed that are capable of emitting various combinations of peak wavelengths across a broad electromagnetic spectrum, including one or more combinations of ultraviolet, visible, and infrared peak wavelengths. Such LED packages may also be broadly tunable across portions of the electromagnetic spectrum ranging from ultraviolet to infrared wavelengths. By providing such capabilities within a single light source provided by a single LED package, larger and more complex systems for broadband emissions that include multiple light sources, complex optical systems, mirrors, filters, and additional components may be avoided. LED chip arrangements, control schemes, and encapsulant arrangements are also disclosed for such broad electromagnetic spectrum LED packages.
