Abstract:
A phosphor converted white light emitting device comprises a solid-state light emitter (LED) operable to generate blue light with a dominant wavelength in range 440 nm to 470 nm; yellow to green-emitting phosphor operable to generate light with a peak emission wavelength in a range 500 nm to 550 nm; and a red-emitting manganese-activated fluoride phosphor such a manganese-activated potassium hexafluorosilicate phosphor (K2SiF6:Mn4+). The yellow to green and red-emitting phosphors are incorporated as a mixture and dispersed throughout a light transmissive material with an index or refraction of 1.40 to 1.43. In some embodiments the light transmissive comprises a dimethyl-based silicone. The device can further comprise an orange to red-emitting phosphor operable to generate light with a peak emission wavelength of 580 nm to 620 nm.
