Light emitting device

A light emitting device, comprising:

• a wavelength conversion layer having an upper surface and a lower surface opposite to each other;
• at least one light emitting unit having two electrode pads located on the same side of the light emitting unit, wherein the light emitting unit is disposed on the upper surface of the wavelength conversion layer and exposes the two electrode pads;
• and
• a reflective protecting element encapsulating the light emitting unit and a portion of the wavelength conversion layer, and exposing the two electrode pads of the light emitting unit and the lower surface of the wavelength conversion layer, wherein the reflective protecting element includes a reflective surface, a first side of the reflective surface is in contact with the light emitting unit, and a second side of the reflective surface extends along a direction toward to the wavelength conversion layer and away from the light emitting unit.
