  • Publication number: 20240405185
    Abstract: A LED packaging module includes a plurality of LED chips, a wiring layer, and an encapsulant component. The LED chips are spaced apart, each of which includes chip first, chip second, and chip side surfaces, and an electrode unit. The wiring layer is disposed on the chip second surfaces, has first, second, and side wiring layer surfaces, and is divided into a plurality of wiring parts spaced apart. The first wiring layer surface contacts and is electrically connected to the electrode units. The encapsulant component includes first and second encapsulating layers, covers the chip side surfaces, the chip first surfaces, and the side wiring layer surface, and fills gaps among the wiring parts. Each LED chip has a thickness represented by TA, the first encapsulating layer has a thickness represented by TB, and TA and TB satisfy a relationship: TB/TA?1.

  • Publication number: 20220199592
    Abstract: A light-emitting diode (LED) packaging module includes light-emitting units arranged in an array having m row(s) and n column(s), an encapsulating layer, and a wiring assembly, where m and n each independently represents a positive integer. Each of the light-emitting units includes LED chips each including a chip first surface, a chip second surface, a chip side surface, and an electrode assembly disposed on the chip second surface. The encapsulating layer covers the chip side surface and fills a space among the LED chips. The wiring assembly is disposed on the chip second surface and is electrically connected to the electrode assembly.

  • Publication number: 20220157793
    Abstract: A light-emitting device includes a number (N) of light-emitting units, a number (a) of first metal pads and a number (b) of second metal pads. Each of the light-emitting units includes a number (n) of light-emitting chips each having two distinct terminals, where N and n are integers and N>1, n>?3. The numbers (a) and (b) are integers and a>1, b>1, and the terminals of each of the light-emitting chips are electrically connected to a unique combination of one of the number (a) of first metal pads and a number (b) of second metal pads, respectively. The numbers (N), (n), (a) and (b) satisfy the equation: a*b=n*N.
