    摘要: A light emitting diode (LED) package includes a substrate with a flat top surface, an LED chip mounted on the substrate, and a group of blocking structure and encapsulation body. The LED chip electrically connects with the substrate. The blocking structure surrounds the LED chip. The encapsulation body covers the LED chip. A bottom of the encapsulation body is enclosed by the blocking structure; the encapsulation body has a light outputting surface, and an outer surface of the blocking structure is continuously connected with the light outputting surface. The light outputting surface has a semispherical profile. An angle between a normal line extending from the outer surface of the blocking structure and perpendicular to the substrate and a tangent line tangent to the light outputting surface at a point thereof adjacent to the outer surface is smaller than 60 degrees.
