摘要: A packaging process of a light emitting diode (LED) is provided. First, an LED chip is bonded with a carrier to electrically connect to each other. After that, the carrier is heated to raise the temperature thereof. Next, an encapsulant is formed on the heated carrier by a dispensing process to encapsulate the LED chip, wherein the viscosity of the encapsulant before contacting the carrier is lower than that of the encapsulant after contacting the carrier. Thereafter, the encapsulant is cured.

摘要: A light emitting diode (LED) package includes a carrier, an LED chip, an encapsulant, a plurality of phosphor particles, and a plurality of anti-humidity particles. The LED chip is disposed on and electrically connected to the carrier. The encapsulant encapsulates the LED chip. The phosphor particles and the anti-humidity particles are distributed within the encapsulant. A first light emitted from the LED chip excites the phosphor particles to emit a second light. Some of the anti-humidity particles are adhered onto a surface of the phosphor particles, while the other anti-humidity particles are not adhered onto the surface of the phosphor particles. The anti-humidity particles absorb H2O so as to avoid H2O from being reacted with the phosphor particles. The LED package of the present application has favorable water resistance.
