摘要: A testing apparatus includes a plate unit including at least one chip mounting unit on which a light emitting diode (LED) to be tested is mounted. The chip mounting unit has a first region in which the LED is overlaid and a second region surrounding the first region. The first and second electrode pads are disposed in the first region and include respective extension portions extended toward the second region. A probe portion is configured to connect to the extension portions of the first and second electrode pads. A power control unit is configured to selectively apply test power to the LED through the probe portion. A light measuring unit is configured to measure light properties of light emitted by the LED.
