White light emitting diode package
First Claim
1. A white light emitting diode package comprising:
- a package body;
a first light emitting diode chip received in the package body, and the first light emitting diode chip emitting light in a first wavelength range;
a second light emitting diode chip received in the package body, the second light emitting diode chip spaced from the first light emitting diode chip, and the second light emitting diode chip emitting light in a second wavelength range which is different to the first wavelength range;
at least three of lead frames electrically connected to the first and second light emitting diode chips; and
a light conversion layer configured to cover both of the first and second light emitting diode chips, the light conversion layer serving to convert at least part of light emitted from the first and second light emitting diode chips into a third wavelength range which is different to the first and second wavelength range,wherein the first wavelength range is a range of about 400 nm to about 460 nm, and has a Full Width At Half Maximum (FWHM) of about 10 nm to about 50 nm,wherein the second wavelength range is a range of about 460 nm to about 550 nm, and has a Full Width At Half Maximum (FWHM) of about 10 nm to about 50 nm,wherein the third wavelength range is a range of about 550 nm to about 660 nm,wherein the light conversion layer comprises a resin mixed with a plurality of phosphors, andwherein the plurality of phosphors include spherical or atypical phosphors which emit a specific single wavelength or plural wavelengths of visible light, a peak wavelength of which is in the third wavelength range, and which absorb light in a wavelength range of about 430 nm to about 550 nm.
