Patent ID: 7800125

Claim:
A light-emitting diode (LED) package comprising: a carrier; a LED chip disposed on the carrier; and a lens disposed on the carrier and above the LED chip, a gap is formed between the LED chip and the lens, the lens having: a first surface facing the LED chip; a second surface opposite to the first surface; a protrusion located at the first surface and on an optical axis of the lens, wherein the protrusion has a first subsurface; and at least one protruding ring located at the first surface and surrounding the protrusion, wherein the at least one protruding ring has: a second subsurface surrounding the first subsurface; and a third subsurface connected with and surrounding the second subsurface; wherein the LED chip is adapted to emit a beam, wherein a first part of the beam passes through the first subsurface and the second surface in sequence, wherein a second part of the beam passes through the second subsurface, is totally internally reflected by the third subsurface, and passes through the second surface in sequence, and wherein a third part of the beam passes through the third subsurface and the second surface in sequence.
