The present invention provides a light-emitting diode (LED) device and a method for manufacturing the same. The LED device comprises: a substrate (1); a chip (2) disposed on the substrate (1); and a first lens (3) disposed on the substrate (1) and spaced from the chip (2); wherein the first lens (3) comprises luminescent powder (7) and at least one of light-diffusing particles (8) and light-reflecting particles (10). The LED device provided by the present invention has a high luminous efficiency, and solves the problem in the prior art that the LED device has a small angle of emergence and the emergent light emergence lacks of uniformity.
