  • Patent number: 8581117
    Abstract: A plurality of conductive areas is formed on a conductive substrate which includes a frame. Each of the conductive areas includes a lead frame and two electrodes. The frame includes a first side and an opposite second side. The lead frame includes first and second lead frame beams. The first and second lead frame beams extend from the first side toward the second side to connect with the two electrodes. The first and second electrodes extend respectively from the first and second lead frame beams. Each conductive area also includes a supporting portion interconnecting the electrodes and the frame to reinforce the connection between the frame and the conductive area so that the conductive area can sustain a pressure when an insulation shell is injection molded on the conductive area.

  • Patent number: 8569781
    Abstract: An LED package comprises a substrate, a reflector, a light-absorbing layer, an encapsulation layer and an LED chip. The light-absorbing layer is located around the reflector and is able to absorb any light which penetrates through the reflector. Therefore, any vignetting or halation of light from the LED package is prevented. Moreover, the LED package can be constructed on a very small scale with no reduction in its color rendering properties.

  • Patent number: 8569779
    Abstract: An exemplary light emitting diode (LED) package includes a substrate, an electrical member formed on the substrate, an LED chip mounted on the substrate and electrically connected to the electrical member, and a heat-dissipating member formed on the electrical member. The heat-dissipating member helps the LED chip to dissipate heat generated thereby when the LED chip is in operation.
