Abstract:
1. An optical device comprising: a substrate member having an upper surface; a light emitting diode (LED) device configured to emit light in a first selected wavelength range, the LED device mounted on the upper surface of the substrate member; a reflective member surrounding the LED device, the reflective member comprising: a first wavelength-selective material disposed on the upper surface of the substrate member, an upper surface of the wavelength-selective material being below an upper surface of the LED device; a second wavelength-selective material disposed on the upper surface of the substrate member; and a third wavelength-selective material disposed on the upper surface of the substrate member; wherein the first wavelength-selective material emits light in a second selected wavelength range in response to light at the first selected wavelength range emitted from the LED device; and wherein the reflective member transmits substantially all of the light at the second selected wavelength range from the optical device.
