Abstract
A light emitting diode (LED) package unit, including a substrate having a concave, a LED chip, at least two electrodes, at least two wires, a gel and a first wavelength-converting material. The LED chip, disposed in the concave, including a top-face, a bottom-face for jointing with the substrate, and at least two chip-electrodes. The LED chip emits light of a first wavelength. The electrodes are disposed on the substrate. The wires are respectively connecting one of the chip-electrode with one of the electrode. The gel is disposed to seal the LED chip and the wires. The first wavelength-converting material including Sr—Si—O—N:Eu is doped within the gel. The first wavelength-converting material absorbs light of the first wavelength and emits light of a second wavelength longer than the first wavelength.
