Claim Text:
1. A light emitting element comprising: a substrate having a plurality of first concaves and a plurality of second concaves, wherein a volume of each first concave is different from a volume of each second concave, and a depth of each of the first concaves is different from a depth of each of the second concaves; a plurality of first light emitting diode chips, wherein a volume of each first light emitting diode chip is less than the volume of each first concave, and the first light emitting diode chips are located within the first concaves; and a plurality of second light emitting diode chips, wherein a volume of each second light emitting diode chip is less than the volume of each second concave, and the second light emitting diode chips are located within the second concaves; wherein the depth of each of the first concaves is greater than the depth of each of the second concaves, a thickness of each of the first light emitting diode chips is greater than a thickness of each of the second light emitting diode chips, and the thickness of each of the first light emitting diode chips is greater than the depth of each of the second concaves.
