Zusammenfassung:A light-emitting diode chip includes an illuminating body and a first phosphor layer. The first phosphor layer is disposed on the illuminating body, and the first phosphor layer includes multiple first phosphor powder groups and multiple second phosphor powder groups. The illuminating body has a first emission wavelength, the first phosphor powder groups have a second emission wavelength, and the second phosphor powder groups have a third emission wavelength. The first wavelength is smaller than the second emission wavelength, and the second emission wavelength is smaller than the third emission wavelength.
