The invention discloses a light-emitting patch structure for providing a predetermined wavelength light source, which comprises a patch substrate, a light-emitting unit and a power supply unit, wherein the patch substrate comprises a first surface and a second surface arranged opposite to each other with the first surface. The light-emitting unit is arranged on the first surface of the patch substrate. The power supply unit is arranged on the second surface of the patch substrate and is electrically connected with the light-emitting unit so that the light-emitting unit generates the light source of the predetermined wavelength.本創作公開一種用於提供一預定波長光源的發光貼片結構，其包括一貼片基材、一發光單元以及一電力供應單元，其中，所述貼片基材包括一第一表面以及與所述第一表面彼此相反設置的一第二表面。所述發光單元設置於所述貼片基材的所述第一表面。所述電力供應單元設置於所述貼片基材的所述第二表面且電性連接所述發光單元，以使所述發光單元產生所述預定波長光源。
