Abstract
A light-emitting diode structure is provided. The light-emitting diode structure includes a light-emitting diode chip, a lead frame for electrically connecting and supporting the light-emitting diode chip, and a lens covering the light-emitting diode chip and to partially cover the lead frame. A recess disposed on the upper portion of the lens has a ladder-like inner wall formed of an upper inclined wall portion, a lower inclined wall portion, and a connecting wall portion connected to the upper and lower inclined wall portions. The slope of the upper inclined wall portion is greater than that of the lower inclined wall portion, and the slope of the connecting wall portion is greater than the upper and lower inclined wall portions.
