Patent ID: 7772603

Claim:
An array type light-emitting device with high color rendering index, comprising: a substrate; an array type light-emitting module electrically disposed on the substrate, wherein the array type light-emitting module is composed of a plurality of light-emitting chip rows, and each light-emitting chip row has a plurality of first light-emitting chips with an emission wavelength range between 450 nm and 460 nm and at least one second light-emitting chip with an emission wavelength range between 620 nm and 640 nm; a plurality of wavelength-converting layers respectively covered on the first light-emitting chips, wherein one part of the wavelength-converting layers is a mixture of green phosphor powders and a package colloid in order to generate projecting sources with an emission peak wavelength range between 520 nm and 540 nm from one part of the corresponding first light-emitting chips, and another part of the wavelength-converting layers is a mixture of yellow phosphor powders and a package colloid in order to generate projecting sources with a predetermined color temperature from another part of the corresponding first light-emitting chips; and a plurality of transparent layers respectively covered on the second light-emitting chips; whereby, a part of visible light emitted by the first light-emitting chips is absorbed and converted into visible light with another emission peak wavelength range via the wavelength-converting layers, and the visible light with another emission peak wavelength range mixes with projecting light projected from the second light-emitting chips to make the array type light-emitting device generate mixed white light with a color rendering index of between 90 and 95.
