PURPOSE: A light emitting diode light source is provided to reduce the size of an light emitting diode chip by packaging an optical confinement part with the light emitting diode chip into an integrated shape. CONSTITUTION: A light emitting diode chip(110) converts electric energy into light energy. The light emitting side of the light emitting diode chip emits light. An optical confinement part(120) confines light emitted from the light emitting diode chip in order to reduce etendue, and the loss of light is reduce. The light emitting diode chip and the optical confinement part are package into an integrated shape.
