  • 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.

  • Patent number: 9690030
    Abstract: A light emitting device capable of bonding a lens at a preset accurate position, and a backlight unit comprising the same are provided. The light emitting device includes a molded material having an opening through which light generated from a light emitting element disposed in the molded material is emitted, a projecting support disposed along at least part of a circumference of the opening of the molded material, and a lens having an inner surface that defines an internal surface on which light emitted from the light emitting element is incident, an outer surface that defines an external surface from which the incident light is emitted to the outside, and a bottom surface that connects the inner surface and the outer surface, wherein a boundary between the inner surface and the bottom surface, a lower part of the inner surface, or the bottom surface contacts the projecting support.
