1. A classification device for sorting and classifying LED lighting according to form of housing through vision recognition from LED-mixed waste lighting having different forms of housing, the classification device comprising:
an input conveyor configured to move a plurality of LED-mixed waste lighting, including bulb-type LED lighting, but having different forms of housing;
a sensing part configured to obtain images of the LED-mixed waste lighting moving along a path of the input conveyor using a plurality of cameras;
an analysis part configured to search for bulb-type LED lighting from the images obtained from the sensing part using an algorithm for image classification and recognition;
a computation unit configured to calculate X, Y, and Z coordinate positions of an object classified as bulb-type LED lighting in the analysis part; and
a conveying part configured to pick up and convey the object with the X, Y and Z coordinates calculated by the computation unit to a classifying conveyor,
wherein the bulb-type LED lighting and remaining types of LED lighting are automatically sorted and separated.
