摘要：
A light emitting diode (LED) bulb configured to scatter certain wavelengths of light. The LED bulb includes a base having threads, a bulb shell, at least one LED, and a plurality of particles disposed within the bulb shell. The plurality of particles has a first and second set of particles. The first set of particles is configured to scatter short wavelength components of light emitted from the at least one LED and has particles with an effective diameter that is a fraction of the dominant wavelength of the light emitted from the at least one LED. The second set of particles is configured to scatter light emitted from the at least one LED, and has particles with an effective diameter equal to or greater than the dominant wavelength of the light emitted from the at least one LED.
