The LED emitting light on four sides includes metallic substrates, a blue chip, golden lines, light emitting materials and a reflective white adhesive layer. The metallic substrates include a first metallic substrate and a second metallic substrate. A transparent holder is fixated with the first metallic substrate and the second metallic substrate, forming a containing cavity. A light emitting chip is across disposed on the first metallic substrate and the second metallic substrate. The light emitting materials are filled in the containing cavity and covering the blue chip. The reflective white adhesive layer is disposed on a top surface of the light emitting materials. The LED emitting light on four sides provided by the disclosure is simply manufactured and low in costs. ## Claims ### Claim 1 A LED emitting light on four sides, comprising: metallic substrates, comprising a first metallic substrate and a second metallic substrate disposed separately;
