Abstract
A device for collecting semiconductor light emitting diodes according to an embodiment of the present disclosure includes an electromagnet portion disposed in a fluid chamber into which semiconductor light emitting diodes including a magnetic material are put to form a magnetic field when power is applied, a power supply portion connected to the electromagnet portion and applying power to the electromagnet portion, and a driving portion moving the electromagnet portion in a width direction, in a longitudinal direction, and in a height direction of the fluid chamber, in which the electromagnet portion guides the semiconductor light emitting devices to a surface on which a magnetic field is formed when power is applied.
