Abstract
A detection apparatus comprising a chuck, a probe device, a light-sensing device and a light-concentrating unit is disclosed. The chuck bears light-emitting diode chips. The probe device includes two probes and a power supply. The end point of the probes respectively electrically connects with one of the light-emitting diode chips and the power supply to make the light-emitting diode chip emits a plurality of light beams. The light-sensing device is disposed on one side of a light-emitting surface of the light-emitting diode chip so as to receive the light beams emitted by the light-emitting diode chip. The light-concentrating unit is disposed between the light-emitting diode chip and the light-sensing device to concentrate the light beams emitted by the light-emitting diode chip.
