  • Apparatus for measuring the optoelectronic characteristics of light-emitting diode with a light gathering unit completely covers a sample holder during the measurement
    Patent number: 9404962
    Abstract: An apparatus for measuring the optoelectronic characteristics of a light-emitting diode includes: a container including a light input port and a light output port; a measurement module connected to the light output port of the container; a sample holder under the container for holding a light-emitting diode under test, wherein a surface of the measurement module reflects more than 50% of the luminous flux generated by the light-emitting diode under test; and a light gathering unit between the container and the sample holder, wherein an interior wall of the light gathering unit reflects more than 50% of the luminous flux generated by the light-emitting diode under test.
