Abstract
A light source module includes first LED elements that emit blue light, second LED elements that emit amber light, and a wavelength conversion member disposed in optical paths of the first LED elements and the second LED elements. The wavelength conversion member converts a portion of the blue light emitted by the first LED elements to yellow light, transmits a portion of the blue light emitted by the first LED elements, and substantially transmits the amber light emitted by the second LED elements.
