Abstract
Solid-state lighting devices including light-emitting diodes (LEDs) and more particularly cover structure arrangements for packaged LED devices are disclosed. Cover structures include light-absorbing layers configured to absorb certain wavelengths of light while permitting other wavelengths to pass therethrough. Light-absorbing layers may include pigment materials of colors that absorb intended wavelengths of light. In certain aspects, an LED package may include an LED chip configured to emit light of a first peak wavelength and a cover structure that includes a light-absorbing layer with a pigment of a color that absorbs the first peak wavelength. Such an arrangement may be useful for embodiments that also include a lumiphoric material that converts a portion of the first peak wavelength to light of a second peak wavelength. Cover structures may include one or more combinations of light-absorbing layers, antireflective layers, and reflective layers for providing improved emission characteristics for the LED package.
