Abstract: 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.
