Abstract: Provided is a system for distributed processing of data that includes a data storage storing raw data generated in a fabrication process in real time; a database storing information associated with each of the raw data in real time; a master service that monitors the database on the basis of the information, selects processing targets to be processed among the raw data, and stores metadata associated with the processing targets in a queue; and a plurality of pods which make requests for jobs to the master service, receive metadata from the master service, access the raw data stored in the data storage using the received metadata, and perform the jobs on the raw data.

Abstract: Provided is a white LED device. The white LED device includes a blue LED chip configured to emit blue light of a wavelength range of about 440 nm to 490 nm, a yellow phosphor formed on the blue LED chip and excited by the blue light to emit yellow light of a wavelength range of about 560 nm to 615 nm, a green LED chip configured to emit green light of a wavelength range of about 500 nm to 560 nm, and a red phosphor formed on the green LED chip and excited by the green light to emit red light of a wavelength range of about 615 nm to about 670 nm.
