  • Apparatus for inspecting light emitting diode package and inspecting method using the same
    Patent number: 8890533
    Abstract: An apparatus for inspecting a light emitting diode (LED) package is provided to inspect an LED to determine whether or not it is defective, and discard the LED when the LED is defective. The apparatus for inspecting an LED package includes: an inspection unit inspecting an LED through a visual inspection to determine whether or not the LED is defective; and a defective product rejection unit discarding the LED when the LED is determined to be defective on the basis of inspection results from the inspection unit among LEDs supplied from the inspection unit. Because the operation of inspecting LEDs and discarding a defective LED are automated and can be rapidly processed as a sequential process, productivity can be improved.
