6. The decorative film of claim 5, wherein the uniform gloss ink layer comprises a first uniform gloss ink layer and a second uniform gloss ink layer;

the first light-homogenizing printing ink layer and the second light-homogenizing printing ink layer are respectively arranged on two opposite sides of the semitransparent colorful printing ink layer in the thickness direction, or the first light-homogenizing printing ink layer and the second light-homogenizing printing ink layer are mutually stacked and arranged between the semitransparent colorful printing ink layer and the membrane body, or the first light-homogenizing printing ink layer and the second light-homogenizing printing ink layer are mutually stacked and arranged on one side, away from the membrane body, of the semitransparent colorful printing ink layer.

7. The decorative film according to claim 1, further comprising an adhesive layer having a light-transmitting property, the adhesive layer being provided on a side of the film body and the decorative layer adjacent to the light-emitting element, the adhesive layer being used for adhering a light-emitting surface of the light-emitting element.

8. The decorative film of claim 7, wherein the adhesive layer is made of printing ink, and the adhesive layer is adhered to the light emitting surface of the light emitting element by means of hot pressing; or the adhesive layer is made of transparent or white OCA glue and is directly adhered to the light emitting surface of the light emitting element.

9. A lighting module comprising a lighting element and a decorative film as claimed in any one of claims 1 to 8, covering the light-emitting surface of the lighting element.

10. The light emitting module of claim 9, wherein the light emitting element comprises a circuit board, a plurality of light emitting chips disposed on the circuit board, and a light conversion medium layer covering the plurality of light emitting chips, and a surface of the light conversion medium layer on a side away from the circuit board is a light emitting surface of the light emitting element.

11. The lighting module of claim 10, wherein the plurality of light emitting chips comprise at least one of LEDs, mini-LEDs, and Micro-LEDs, and the light conversion medium layer is a phosphor layer or a QD layer.

12. An electronic device, comprising a housing and the light-emitting module of any one of claims 9-11, wherein the housing is provided with a transparent region, and the light-emitting module is located inside the housing and visually displayed on the housing through the transparent region.

13. The electronic device according to claim 12, further comprising an electronic component disposed inside the housing, wherein the electronic component is visually displayed on the housing through the transparent region, and the light emitting module is disposed around the electronic component.
