Beam shaping spectrally filtering optics and lighting devices using high-intensity narrow-spectrum light output

A method of making a lighting device comprising:

• mixing a filtering agent with an optical material;
• shaping the result of the mixing to form a filtering optic device;
• coupling the filtering optic device to at least one LED that emits light waves in a first range of wavelengths, wherein the filtering agent filters light having a preselected subrange of wavelengths within the first range of wavelengths to generate a first filtered light and the filtering optic device controls a shape of a beam of the filtered light;
• and
• combining the filtered light with a high-intensity narrow-spectrum focused light output to provide medical sterilization.

A lighting device comprising:

• a housing;
• a first light source positioned in the housing, the first light source emitting light having a first bandwidth;
• a second light source positioned in the housing, the second light source emitting light having a high-intensity narrow-spectrum focused light output, wherein the second light source is configured for medical sterilization;
• a first optic device coupled to the first light source, wherein the first optic device filters light having a preselected subrange of wavelengths within the first bandwidth and generates a first filtered light;
• a second optic device coupled to the second light source, wherein the second optic device permits the second bandwidth of light to pass through it unfiltered;
• and
• a control device operably connected to the first and second light sources and operable to control whether light is emitted from one, both or neither of the first and second light sources.
