WIPO Patent Application WO/2023/123538

A1

A composite film layer capable of transmitting white light, which is used in the technical field of light emission. The composite film layer capable of transmitting white light comprises a transparent panel and an indium plating layer, wherein the transparent panel is closer to a white light source relative to the indium plating layer; and the transparent panel is formed by mixing transparent plastics and a blue pigment and performing injection moulding, or is formed by mixing transparent plastics, a blue pigment and a purple pigment and performing injection moulding. The transparent panel containing the blue pigment or the blue pigment and the purple pigment is attached to one side of the indium plating layer by using the principle of complementary colours in chromatics, so that the composite film layer can transmit white light, and a colour temperature value of the transmitted white light is 5200 to 7200 K.
