Estimating the term…
A light-emitting device includes: a substrate; a light-emitting chip, disposed on the substrate; and a phosphor encapsulant covering the light-emitting chip. The phosphor encapsulant includes a narrowband phosphor. The phosphor encapsulant includes a first phosphor layer, covering an upper surface of the light-emitting chip, and a second phosphor layer, disposed on the first phosphor layer. In the light-emitting device, the first phosphor layer covers the upper surface of the light-emitting chip, the second phosphor layer covers the first phosphor layer, the first phosphor layer includes the narrowband phosphor and the silicone, and the narrowband phosphor is uniformly distributed within the silicone, so that the narrowband phosphor is close to the light-emitting chip, and the narrowband phosphor has high pureness in the silicone, which can improve an excitation efficiency of the narrowband phosphor, and improve heat dissipation efficiency.
