    摘要: A lighting apparatus includes a substrate, a plurality of light-emitting dies, a continuous encapsulation structure, and a gel. The plurality of light-emitting dies are disposed on the substrate and spaced apart from one another. The light-emitting dies each are covered with a respective individual phosphor coating conformally. The continuous encapsulation structure has a curved surface disposed over the substrate and encapsulates the light-emitting dies within. The gel is disposed between the encapsulation structure and the phosphor coating for each of the light-emitting dies. The gel contains diffuser particles. The lighting apparatus has a substantially white appearance in an off state when the plurality of light-emitting dies is turned off.

    摘要: The present disclosure involves a method of packaging a light-emitting diode (LED). According to the method, a group of metal pads and a group of LEDs are provided. The group of LEDs is attached to the group of metal pads, for example through a bonding process. After the LEDs are attached to the metal pads, each LED is spaced apart from adjacent LEDs. Also according to the method, a phosphor film is coated around the group of LEDs collectively. The phosphor film is coated on top and side surfaces of each LED and between adjacent LEDs. A dicing process is then performed to slice through portions of the phosphor film located between adjacent LEDs. The dicing process divides the group of LEDs into a plurality of individual phosphor-coated LEDs.
