  • Patent number: 7963674
    Abstract: A light emitting diode package comprising a substrate electrically connectable to an external unit with a reduced height. A flexible PCB for electrical connection between a light emitting diode and the external unit is directly connected to a light emitting element. The direct connection is conducted by applying a conductive resin to an electrode on the flexible PCB, on which the light emitting element is mounted; mounting the light emitting element; curing the conductive resin in a high-temperature furnace. The present invention requires neither a lead frame for electrical connection of the light emitting element to the flexible PCB nor a rigid PCB for supporting the flexible PCB, thus reducing the total height of the light emitting diode package.

  • Patent number: 7214116
    Abstract: A light-emitting diode with no fluctuations in optical properties and good sealing properties, and a simple production method for producing this light-emitting diode. The light-emitting diode has a base comprising a cup part on which the light-emitting diode is placed, a resin material introduced into cup part, and a lens member placed on top of a cup for focusing light emitted by a light-emitting diode chip. A layer of fluorescent material, which converts the wavelength of at least some of the light from the light-emitting diode chip, is applied to the inner convex face of the lens member. When the lens member is attached to the base, the inner convex face deforms the resin material and air and excess resin material can be pushed to the outside.
