  • Publication number: 20100219428
    Abstract: A warm white light emitting apparatus includes a first light emitting diode (LED)-phosphor combination to generate a base light that is white or yellowish white and a second LED-phosphor combination to generate a Color Rendering Index (CRI) adjusting light. The base light and the CRI adjusting light together make a warm white light having a color temperature of 2500 to 4500K.

  • Publication number: 20090243457
    Abstract: The present invention relates to a white light emitting diode (LED) package that includes a blue LED chip to emit blue light; a yellow phosphor excited by the blue light and emit yellow light, the yellow light to produce a primary white light in combination with the blue light; a red LED chip to emit red light, the red light to adjust the primary white light into secondary white light of an incandescent color; and a package member comprising at least a partial transmissive part covering the blue LED chip, the red LED chip, and the yellow phosphor. The primary white light falls in a region of (0.413, 0.502), (0.335, 0.376), (0.37, 0.371), and (0.439, 0.48) based on a CIE color coordinate standard.

  • Publication number: 20080268559
    Abstract: There are provided a mold for forming a molding member and a method for forming a molding member using the same. The mold includes an upper surface, and a lower surface having an outer peripheral surface and a concave surface surrounded by the outer circumference. Injection and discharge holes extend from the upper surface to the lower surface. Accordingly, after the mold and the package are coupled so that the discharge hole is directed upward, a molding member can be formed on the package by injecting the molding material through the injection hole, whereby it is possible to prevent air bubbles from being captured in the molding member.
