Providing remote blue phosphors in an LED lamp

An LED lamp comprising:

• a first plurality of n radiation sources configured to emit radiation characterized by a first wavelength, the first wavelength being substantially blue;
• and
• a second plurality of m radiation sources configured to emit radiation characterized by a second wavelength, the second wavelength being substantially violet;
• and
• a first wavelength converting layer configured to absorb at least a portion of radiation emitted by the second plurality of radiation sources, the first wavelength converting layer having an emission wavelength ranging from about 500 nm to about 750 nm.

An LED lamp with an outer surface having a white appearance under ambient light, comprising:

• a light source;
• an outer surface, the outer surface positioned to form a remote structural member;
• a first wavelength converting layer disposed on the remote structural member, the first wavelength converting layer configured to absorb at least a portion of radiation emitted by the light source, the first wavelength converting layer having an emission wavelength ranging from about 420 nm to about 520 nm;
• and
• a second wavelength converting layer disposed on the remote structural member, the second wavelength converting layer having an emission wavelength ranging from about 490 nm to about 630 nm.
