Title: LED package structure having a light-projecting angle adjusting function

Abstract: A LED package structure includes a substrate unit, a light-emitting unit, a support unit, a lens unit, an input unit and a control unit. The light-emitting unit includes at least one light-emitting element electrically connected to the substrate unit. The support unit includes a support element disposed on the substrate unit and surrounding the light-emitting element. The lens unit includes an electrically-controlled zoom lens disposed above the light-emitting element and retained by the support element. The input unit includes a signal input module for providing a predetermined voltage signal. The control unit includes a voltage controlling module electrically connected between the electrically-controlled zoom lens and the signal input module. Therefore, the voltage controlling module provides a predetermined voltage value for the electrically-controlled zoom lens according to the predetermined voltage signal, and the variable focal length of the electrically-controlled zoom lens is adjusted according to the predetermined voltage value.
