Abstract
An LED package structure for increasing light-emitting efficiency and controlling light-projecting angle includes a substrate unit, a light-emitting unit, a light-reflecting unit and a package unit. The substrate unit has a substrate body and a chip-placing area disposed on a top surface of the substrate body. The light-emitting unit has a plurality of LED chips electrically disposed on the chip-placing area. The light-reflecting unit has an annular reflecting resin body surroundingly formed on the top surface of the substrate body by coating. The annular reflecting resin body surrounds the LED chips that are disposed on the chip-placing area to form a resin position limiting space above the chip-placing area. The package unit has a translucent package resin body disposed on the top surface of the substrate body in order to cover the LED chips. The position of the translucent package resin body is limited in the resin position limiting space.
