Abstract
A converging element for an LED is described, which is used for converging light rays emitted from a light-emitting chip to enable the light rays to form approximately parallel light rays after passing through the converging element. The converging element for LED includes a cylinder and a first lens. The cylinder is disposed on the light-emitting chip. The first lens is disposed on the other end of the cylinder opposite to the light-emitting chip. The first lens has a first plane and a first curved surface opposite to each other. The first plane of the first lens is attached to the cylinder.
