INSPECTION APPARATUS AND METHOD OF LIGHT EMITTING DEVICE

摘要

PURPOSE: A light emitting diode inspection device and method are provided to inspect electric characteristics, optical characteristics and the defect of appearance state of a light emitting diode. CONSTITUTION: A probing unit(400) comprises a table in which a light emitting diode is loaded and a probe which supplies a current to the light emitting diode. An image acquiring unit(200) obtains an image of the light emitting diode. A determining unit(300) detects whether a light emitting cell emits light or not from luminance information of the image. The determining unit determines the open/short failure of the light emitting diode. A measuring unit(100) comprises an integrating sphere(120) and a detector(110). The integrating sphere collects light emitted from the light emitting diode by being placed on the upper side of the table. The detector detects optical characteristic of the light emitting diode from the integration sphere.
