Patent ID: 8569949

Claim:
A light emitting diode (LED) light bulb, comprising: a base having threads; a bulb shell connected to the base and enclosing an inner portion of the LED bulb; a plurality of particles disposed within the bulb shell; at least one LED centrally located in the inner portion of the LED bulb, the at least one LED configured to emit light at a dominant wavelength; and wherein said plurality of particles comprises: a first set of particles configured to scatter short wavelength components of the light emitted from the at least one LED, where the particles of the first set have an effective diameter that is a fraction of the dominant wavelength of the light emitted from the at least one LED; and a second set of particles configured to scatter the light emitted from the at least one LED, wherein the particles of the second set comprise a non-phosphor material different than the particles of the first set and have an effective diameter equal to or greater than the dominant wavelength of the light emitted from the at least one LED.
