Abstract: Disclosed is a method for testing a light-emitting device comprising the steps of: providing an integrating sphere comprising an inlet port and a first exit port; disposing the light-emitting device close to the inlet port of the integrating sphere; providing a current source to drive the light-emitting device to form an image of the light-emitting device in driven state; providing an image receiving device and to receive the image of the light-emitting device, wherein the image receiving device is connected to the first exit port of the integrating sphere; and determining a luminous intensity of the light-emitting device according to the image. An apparatus for testing a light-emitting device is also disclosed. The apparatus for testing a light-emitting device comprises: an integrating sphere comprising an inlet port and a first exit port, wherein the light-emitting device is disposed close to the inlet port of the integrating sphere; an image receiving device connected to the first exit port of the integrating sphere for receiving an image of the light-emitting device; and a processing unit coupled to image receiving device for determining a luminous intensity of the light-emitting device.
