An LED package includes a silicon base, an LED and a glass encapsulant. The silicon base has a first surface and a second surface opposite to the first surface. The LED chip is located on the first surface of the silicon base. The glass encapsulant covers the LED chip. The glass encapsulant and the silicon base define a receiving space therebetween to receive the LED chip. The glass encapsulant is fixedly engaged with the first surface of the silicon base, so the glass encapsulant and the silicon base enclose the LED chip.

A method for manufacturing a phosphor film for use in the an LED package, includes following steps: providing a mold comprising a first and a second molding part, the first molding part and the second molding part cooperatively forming a molding chamber, the first molding part defining an opening communicating with the molding chamber; filling a mixture of phosphor particles and a transparent glue into the first opening; moving a piston in the first opening along a direction from the first molding part to the second molding part, thereby pressing the mixture into the molding chamber; solidifying the mixture to form a phosphor film; and removing the phosphor film from the mold. The phosphor film is used to be attached to a top face of an LED chip opposite a substrate on which the LED chip is mounted.

An LED lamp structure includes a heat sink and a base. The heat sink includes a first receiving cavity, a second receiving cavity opposite to the first receiving cavity and a partition. A light board having LED modules is mounted on the partition. The partition defines two first threaded through holes therein. The base has two positioning protrusions engaging in two positioning grooves of the heat sink. Thus, second screw holes of two screw pillars of the base are aligned at the first screw holes of the partition of the heat sink. Screws are used to threadedly engage in the first screw holes, the second screw holes and third screw holes in the light board to thereby assemble the heat sink, the base and the light board together.
