Abstract
A light source module includes a substrate, a first LED package and a second LED package. The first and second LED packages are disposed on the substrate. The first LED package includes a first blue LED chip and a first phosphor. The first blue LED chip emits light in the range of the wavelength for blue light. The first phosphor is used to convert the wavelength of a portion of the light emitted from the first blue LED chip. The second LED package includes a second blue LED chip and a second phosphor. The second blue LED chip emits light in the range of the wavelength for blue light. The second phosphor is used to convert the wavelength of a portion of the light emitted from the second blue LED chip. The wavelength associated with the second phosphor is greater than that associated with the first phosphor.
