发明名称 SINGLE-COLOR WAVELENGTH-CONVERTED LIGHT EMITTING DEVICES
摘要 A packaged light emitting device (LED) (10) includes an LED chip (12) configured to emit light within a first wavelength range, and a wavelength conversion material (16) on the LED chip. The wavelength conversion material is configured to receive the light within the first wavelength range and responsiveIy emit light within a second wavelength range different than the first wavelength range such that a light output of the packaged LED does not substantially include the light within the first wavelength range and provides an appearance of substantially monochromatic light of a color of the visible spectrum corresponding to the second wavelength range. The packaged LED may include a color filter on the wavelength conversion material that is configured to prevent passage of the light within the first wavelength range therethrough, and/or may include a thickness of the wavelength conversion material configured to completely absorb the light within the first wavelength range.
