This application is a Continuation of U.S. patent application Ser. No. 13/476,986, filed May 21, 2012, which is a Continuation of U.S. patent application Ser. No. 12/299,088, filed Oct. 30, 2008, which is an application filed under 35 U.S.C. §371 and claims priority to International Application Serial No. PCT/US2007/010467, filed Apr. 27, 2007, which claims priority to U.S. Patent Provisional Application No. 60/797,118 filed May 2, 2006 which is incorporated herein by this reference in its entirety.
1. A light-emitting diode (LED) bulb, comprising:
at least one LED located in the inner portion of the LED bulb, the at least one LED configured to emit light at a dominant wavelength; and
a plurality of particles configured to scatter light emitted from the at least one LED,
a first set of particles disposed within the inner portion of the LED bulb, wherein the particles of the first set have an effective diameter less than the dominant wavelength of the light emitted from the at least one LED; and
a second set of particles intermixed with the first set of particles, wherein the particles of the second set are comprised of a different material 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.
15. A method of making a light-emitting diode (LED) bulb, comprising:
connecting a bulb shell to a base to enclose an inner portion of the LED bulb, wherein at least one LED is located in the inner portion of the LED bulb; and
disposing, within the inner portion of the LED bulb, a plurality of particles configured to scatter light emitted from the at least one LED,
a first set of particles having an effective diameter that is less than a dominant wavelength of the light emitted from the at least one LED; and
a second set of particles intermixed with the first set of particles, wherein the particles of the second set comprise a different material 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.
