  • Patent number: 9078312
    Abstract: A multichip package structure includes a substrate unit, a light-emitting unit, a control module, a frame unit and a package unit. The substrate unit includes a first chip-placing region and a second chip-placing region. The light-emitting unit includes a plurality of light-emitting chips electrically connected to the first chip-placing region. The control module includes at least one current-limiting unit and the rectifier unit electrically connected to the second chip-placing region and the light-emitting unit. The frame unit includes a first annular colloid frame surrounding the light-emitting chips and a second annular colloid frame surrounding the current-limiting unit and the rectifier unit. The package unit includes a first package colloid body surrounded by the first annular colloid frame to cover the light-emitting chips and a second package colloid body surrounded by the second annular colloid frame to cover the current-limiting unit and the rectifier unit.

  • Patent number: 8421373
    Abstract: A light-mixing multichip package structure includes a substrate unit, a light-emitting unit, a frame unit, and a package unit. The light-emitting unit includes at least one first light-emitting module with red light-emitting chips and at least one second light-emitting module with blue light-emitting chips. The frame unit includes at least one first continuous colloid frame and at least one second continuous colloid frame respectively surrounding the first light-emitting module and the second light-emitting module. The package unit includes a transparent colloid body and a phosphor colloid body respectively covering the first light-emitting module and the second light-emitting module. Hence, when the red light source generated by matching the red light-emitting chips and the transparent colloid body and the white light source generated by matching the blue light-emitting chips and the phosphor colloid body are mixed with each other, the CRI of the light-mixing multichip package structure can be increased.
