Abstract:
1. A system for testing light-emitting devices in a batch-wise, comprising: a base for uploading and energizing purposely a plurality of light-emitting devices, each of the light-emitting devices further having a plurality of light-emitting elements; a test area located over the base to define a limited space for testing the light-emitting devices, wherein the base only energizes the light-emitting elements in the test area; a moving carrier unit for transporting the light-emitting devices in a batch-wise to pass the base and the test area for testing; and a solar cell module for detecting the light-emitting elements in the test area, mounted in the test area in a location above the base, said solar cell module including at least a solar cell, said at least one solar cell including at least an action surface to face said base as well as said light-emitting elements on said base, said action surface being spaced from said light-emitting devices on said base by a predetermined distance in a manner that photo energy of said light-emitting elements on said base received by said action surface is substantially greater than photo energy diffused out of said at least solar cell.
