description The utility model discloses a light emitting diode. The light emitting diode comprises a substrate, an LED chip arranged on the substrate and a second glue layer filled around the LED chip and further comprises at least one of a third printing glue layer covered the second glue layer, wherein the third printing glue layer is a second fluorescent glue layer. The second fluorescent glue layer of the LED is printed on a surface of the second fluorescent glue layer, namely, a luminescence face of the LED chip, and a fluorescent glue layer is formed by printing, so position of fluorescent powder at fluorescent glue is relatively fixed, and distribution of the fluorescent powder at the fluorescent glue is more uniform than position distribution of fluorescent powder at fluorescent glue in the prior art, and thereby uniformity of LED luminescence color is improved, moreover, only arrangement of the fluorescent glue layer on the luminescence face of the LED chip is required, and the fluorescent glue is not filled in
