ABSTRACT:
An LED package in which an LED chip a body has a cup part housing an LED chip. The cup part has a step formed in the outer circumference of the top thereof. A lens is mounted on the cup part, and has a flange extended downward from the outer circumference of the lens along the outside wall of the cup part to form a gap between the flange and the downward step of the cup part and to seal the gap from the outside. Resin material fills a space formed between the underside of the lens and the cup part and at least partially the gap formed between the step of the cup part and the lens flange. The resin material is prevented from leaking out of the LED package. The LED package of the invention prevents the creation of voids in the resin material surrounding the LED chip or the leakage of the resin material to the outside.
