Abstract:
1. An LED lighting module comprising: a support board having an upper surface and a lower surface opposite to the upper surface; a first light emitting diode disposed on an upper surface of the support board, and the first light emitting diode comprising a first substrate, a first light emitting layer stack and a first wavelength-converting layer, the first light emitting layer stack being disposed on the first substrate and configured to emit a first wavelength light, the first wavelength- convertin layer being disposed on the first light emitting layer stack and configured to absorb part of the first wavelength light and convert into a second wavelength light; and a second light emitting diode disposed on the upper surface of the support board, and the second light emitting diode comprising a second substrate, a second light emitting layer stack and a second wavelength-converting layer, the second light emitting layer stack being disposed on the second substrate and configured to emit a third wavelength light, the second wavelength-converting layer being disposed on the second light emitting layer stack and configured to absorb part of the third wavelength light and convert into a fourth wavelength light; wherein the total thickness of the first light emitting diode is different from the total thickness of the second light emitting diode.
