First Claim
1. 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 blue light-emitting chip set, a red light-emitting chip set, a green light-emitting chip set, a yellow light-emitting chip set, and an amber light-emitting chip set, wherein said blue light-emitting chip set includes eight blue LED chips arranged in a pair of spaced apart outer-most blue light-emitting chip rows, wherein four of the eight blue LED chips are arranged to form one of said pair of the outer-most light-emitting chip rows, and other four of the eight blue LED chips are arranged to form another of said pair of the outer-most light-emitting chip rows, and wherein said red, green, yellow, and amber light-emitting chip sets are disposed between said outer-most blue light-emitting chip rows;
a wavelength-converting layer set covered on the blue light-emitting chip set; and
a plurality of transparent layer sets respectively covered on the red light-emitting chip set, the green light-emitting chip set, the yellow light-emitting chip set, and the amber light-emitting chip set, other than blue light-emitting chip set;
whereby, a part of visible light emitted by the blue light-emitting chip set is absorbed and converted into visible light with another emission peak wavelength range via the wavelength-converting layer set, and the visible light with another emission peak wavelength range mixes with projecting light projected from the red, the green, the yellow and the amber light-emitting chip sets to make the array type light-emitting device generate white light with a color rendering index of between 90 and 96.

Abstract
An array type light-emitting module includes a blue, a red, a green, a yellow and an amber light-emitting chip sets. Wavelength-converting layer set covers the blue light-emitting chip set. Transparent layer sets cover the red, green, yellow, and amber light-emitting chip sets. A portion of the visible light emitted by the blue light-emitting chip set is converted into visible light with another emission peak wavelength range via the wavelength-converting layer set. The converted visible light mixes with light projected from the red, the green, the yellow and the amber light-emitting chip sets to generate white light with a color rendering index ranging between 90 and 96.
