Abstract
A method for testing light-emitting devices in a batch-wise, associated with a system for the same purpose, comprises the steps of: preparing the light-emitting devices on a moving carrier unit in a manner of aligning a predetermined longitudinal direction of the light-emitting devices with a predetermined transportation direction of the moving carrier unit, each of the light-emitting devices further having plural light-emitting elements; transporting orderly the light-emitting devices to pass a test area on a base of the system, in which the base energizes only the light-emitting elements within the test area; and, a solar cell module detecting continuously the energized light-emitting elements within the test area and further forming signals with respect to photo energy received in the test area.
