Abstract
A comprehensive light-emitting diode device including a translucent substrate, a light-emitting diode chip, a reflective layer, a first wavelength conversion layer, and a second wavelength conversion layer. The translucent substrate includes a first surface and a second surface opposite to the first surface. The light-emitting diode chip is disposed on the first surface. The reflective layer is disposed on the first surface. The light-emitting diode chip is surrounded by the reflective layer. The first wavelength conversion layer is disposed on the first surface. The light-emitting diode chip and the reflective layer are covered by the first wavelength conversion layer.
