ABSTRACT:
Disclosed are a light emitting diode (LED) inspection apparatus, which can determine whether an LED has a defect such as leakage current, without making physical contact with the LED being inspected, and an LED inspection method thereof. The LED inspection apparatus includes an ultraviolet emission unit emitting UV light to an LED, an image generation unit generating an image of the LED to which the UV light is emitted, and a control unit obtaining color or intensity information of the LED from the image of the LED and determining, based on the color information, whether the LED is defective.
