A method of forming a plurality of reflectors for a light emitting device (LED) package includes receiving a first fluid material at at least a first source opening of an upper mold of a transfer apparatus; passing the first fluid material through a transfer passageway of the upper mold; expelling the first fluid material from the transfer passageway through a plurality of openings in a lower internal surface of a transfer chamber of the transfer passageway; depositing the first fluid material on a lead frame, disposed on a lower mold of the transfer apparatus, through the plurality of openings; forming the first fluid material into a plurality of molded structures using the upper mold and the lower mold; and hardening each of the molded structures to form a plurality of reflectors.

Method and device for forming reflector in light emitting device package

A method of light source classification includes determining a plurality of color regions in the CIE 1976 chromaticity diagram according to desired classification criteria. The plurality of color regions of the CIE 1976 chromaticity diagram are converted into a plurality of color classification regions defined by color coordinates of the CIE 1931 chromaticity diagram. The light source is classified into one of the plurality of color classification regions. This classification method may allow for precise classification based on actual color differences, while providing light sources having color uniformity in the same classification region.

Light source classification system and method

A light emitting device package includes a package body; a first light emitting device mounted on the package body and emitting light of a particular color; a second light emitting device mounted on the package body to be adjacent to the first light emitting device, adjusting an amount of light according to a current value applied thereto to thereby control a color temperature, and emitting orange light; and a resin part sealing the first and second light emitting devices and containing at least one or more types of phosphors.
