Abstract
A light-emitting device with multi-color temperature and multi-loop configuration is provided. The light-emitting device may include a substrate, multiple light sources disposed on the substrate, a light-emitting unit covering the light sources, a first circuit and a second circuit. Each light source may be configured to emit a respective primary radiation. The light-emitting unit may include multiple loops, each of which covering at least one of the light sources. Each loop may be adjacent to and in contact with at least another loop. A first number of the light sources covered by one or more odd-numbered loops of the loops may be electrically connected to the first circuit. A second number of the light sources covered by one or more even-numbered loops of the loops may be electrically connected to the second circuit.
