A light-emitting device with multi-color temperature and multi-loop configuration is provided. The light-emitting device comprises a substrate, multiple light sources disposed on the substrate, and a light-emitting unit covering the light sources and at least a portion of the substrate. Each of the light sources is configured to emit a respective primary radiation. The light-emitting unit comprises multiple wavelength conversion components, each of which may include a respective fluorescent material. Each wavelength conversion component emits a respective converted radiation, upon absorbing a portion of the primary radiation from one or more of the light sources, and mixes the respective converted radiation with a portion of the primary radiation from the one or more of the light sources that is not absorbed to form a respective mixed radiation. Each wavelength conversion component is adjacent to, and at least partially contacts, at least another one of the wavelength conversion components.
