  • Method for manufacturing improved chip-on-board type light emitting device package and such manufactured chip-on-board type light emitting device package
    Patent number: 9748459
    Abstract: There are provided a chip-on-board type light emitting device package capable of improving structural reliability and heat-dissipating efficiency and reducing a manufacturing cost, and a method for manufacturing the same. The chip-on-board type light emitting device package includes: a dual frame including a base frame on which a plurality of light emitting devices are mounted and an electrode frame positioned above the base frame so as to be spaced apart from the base frame and including two electrodes separated from each other; and a molding part coupled to the dual frame so that the base frame and the electrode frame are spaced apart from each other and having an opening through which light generated in the plurality of light emitting devices is to be emitted, wherein the base frame has a through-hole through which the electrode frame is exposed.
