摘要:
A white light emitting device may include a substrate, first LEDs disposed on the substrate, a first photoluminescence material disposed over the first LEDs, second LEDs disposed on the substrate, where the first LEDs and the second LEDs emit blue light at substantially the same wavelength, a second photoluminescence material disposed over the second LEDs, the second photoluminescence material having a composition different from the first photoluminescence material, where an emission product of the white light emitting device is a combination of light emitted from (i) a combination of the first LEDs and the first photoluminescence material, and (ii) a combination of the second LEDs and the second photoluminescence material, and a dimming control connected to the first LEDs and to the second LEDs; where the dimming control is actuable to modify the emission product.
