Abstract
A light emitting diode (LED) device includes a transparent substrate, a first reflection layer, a LED chip, a positive electrode, a negative electrode and a wavelength-converting layer. The LED chip is disposed on a surface of the transparent substrate, and the first reflection layer is disposed between the LED chip and the transparent substrate. The positive electrode and the negative electrode are disposed on an end portion of the transparent substrate and are electrically connected with the LED chip. The wavelength-converting layer covers the first reflection layer and the LED chip.
