Abstract
A light emitting device is provided. The light emitting device includes a first white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.4822, 0.3980); a second white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.4180, 0.4337); and a third white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.2806, 0.2981).
Claims20
A light emitting device comprising:
- a first white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.4822, 0.3980);
- a second white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.4180, 0.4337);
- and
- a third white light source emitting a white light of which color coordinates exist within a MacAdam 10-step ellipse from color coordinates (0.2806, 0.2981).
A light emitting device comprising:
- a first white light source comprising a blue LED and phosphors, wherein the phosphors comprise a third phosphor emitting light having a main wavelength of about 555 nm to about 575 nm, and a fourth phosphor emitting light having a main wavelength of about 580 nm to about 610 nm;
- a second white light source comprising the blue LED and phosphors, wherein the phosphors comprise a third phosphor emitting light having a main wavelength of about 555 nm to about 575 nm, and a fourth phosphor emitting light having a main wavelength of about 580 nm to about 610 nm;
- and
- a third white light source comprising the blue light emitting diode (LED) and phosphors, wherein the phosphors comprise a first phosphor or a second phosphor, the first phosphor emitting light having a main wavelength of about 495 nm to about 510 nm and the second phosphor emitting light having a main wavelength of about 550 nm to about 555 nm, a third phosphor emitting light having a main wavelength of about 555 nm to about 575 nm, and a fourth phosphor emitting light having a main wavelength of about 580 nm to about 610 nm.
