Abstract
A light emitting diode package comprises a light emitting diode chip, a first luminescent conversion layer and a separate second luminescent conversion layer on the first luminescent conversion layer. The first luminescent conversion layer has a first luminescent conversion element surrounding the light emitting diode chip. The second luminescent conversion layer has a second luminescent conversion element located above the light emitting diode chip. An excitation efficiency of the first luminescent conversion element is higher than that of the second luminescent conversion element.
