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.
