Abstract
A light emitting diode chip includes a first electrode (13), a reflective layer (11) formed on the first electrode, a light emitting layer (12) formed on the reflective layer and a second electrode (14) arranged on the light emitting layer. The light emitting layer tapers in a direction from the second electrode to the first electrode. Therefore a cross section of the light emitting diode chip is trapezoidal in shape. A light emitting diode includes a base (20), a light emitting diode chip, a first terminal (30), a second terminal (40), a light-permeable cover (50). The present light emitting diode has high light emitting efficiency and low heat emission.
