摘要： A light-emitting device includes: a first laser light source; a first diffusion member provided along a light axis of a first light radiated form the first laser light source; and a first wavelength converter provided along the first diffusion member. The first diffusion member generates a second light from the first light. The second light outgoes in a direction different from the light axis direction of the first light. A ratio of generating the second light from the first light in a first part is higher than that in a second part, wherein an intensity of the first light in the first part is lower than that in a second part. The first wavelength converter absorbs the second light and emitting a third light having a different wavelength from the second light.
