Light-emitting structure

The invention discloses a light-emitting structure. The light-emitting structure comprises a substrate and a light-emitting unit, wherein the substrate is provided with a first conducting trace and a second conducting trace which are in a zigzag shape respectively, and each first chip placement area of the first conducting trace is provided with at least two first chip placement circuits; each second chip placement area of the second conducting trace is provided with at least two second chip placement circuits; the light-emitting unit comprises a plurality of first light-emitting groups and second light-emitting groups; one or more first light-emitting diode chips of each first light-emitting group are arranged on the same first chip placement circuit of the corresponding first chip placement area, and one or more second light-emitting diode chips of each second light-emitting group are arranged on the same second chip placement circuit of the corresponding second chip placement area; the plurality of first chip placement areas and second chip placement areas are mutually and alternately arrayed at intervals, so that the plurality of first light-emitting groups and second light-emitting groups are mutually and alternately arrayed at intervals.
