Abstract
The present invention relates to the field of automotive lamps, particularly a method for manufacturing a light emitting device () for use in automotive lamps. The method comprises: providing a base substrate () with a LED die () and one or more electrical components () attached thereon into a first mold; melting and injecting an optical transparent material over the LED die () to form an optical structure (); removing the base substrate () from the first mold once the optical transparent material is partially solidified; providing the base substrate () into a second mold different from the first mold; and melting and injecting a thermally conductive material into the second mold while the optical transparent material is not fully solidified, such that an intimate connection is formed between the thermally conductive material and the optical transparent material. The present invention further discloses the light emitting device () per se.
