Phosphor composition and light emitting device using the same
The present invention provides a phosphor composition and light emitting device using the same. The phosphor composition includes a first phosphor and a second phosphor, the second phosphor includes Phellodendron extract, Phellodendron extract emits lights with wavelength from 450 nm to 750 nm as it is excited by lights with wavelength from 300 nm to 480 nm. The LED device using the phosphor composition could emit warm white lights with wavelength from 400 nm to 800 nm.
