As shown in fig. 2, when the light emitting structure layer is in a light emitting state, light directly enters the reflective film 12 and the substrate 11 from the outside, and meanwhile, the reflective pattern 121 on the reflective film 12 can reflect the light into the substrate 11, and since the refractive index of the substrate 11 is higher than that of the reflective film 12, the light can be totally reflected in the substrate 11, and finally the light is transmitted to the reflective pattern 121 far away from the light source 2, so as to form an overall light emitting effect of the reflective pattern 121, thereby effectively enlarging the light transmitting area, so as to help the entire reflective film 12 to uniformly emit light. Because the substrate 11 plays a role in light conduction, in the light-emitting structure layer, the requirement on the refractive index of the reflective film 12 is not high, only the light transmittance of the material is needed to be good, the selection range of the reflective film 12 is greatly increased, meanwhile, the substrate 11 with high requirement on the refractive index does not need to be processed with the reflective patterns 121, and the reflective patterns 121 can be arranged on the reflective film, so that the processing difficulty of the reflective patterns 121 is effectively reduced.
In some embodiments, the substrate 11 and the retroreflective film 12 are each independently selected from a transparent layer or a translucent layer, including a colorless translucent layer or a colored translucent layer.

Specifically, in a preferred embodiment, the reflective film 12 is selected from a PET (polyethylene terephthalate) film, which has a certain flexibility to facilitate processing of the reflective pattern 121 on the surface thereof.
In one embodiment, the refractive index of the substrate is 1.4 to 2, and the refractive index of the reflective film is 1.2 to 1.8.
In an embodiment, the light emitting layer 1 further includes a transparent adhesive layer 13, and the transparent adhesive layer 13 is located between the substrate 11 and the reflective film 12.
The transparent adhesive layer 13 is used for fixing the reflective film 12 on the surface of the substrate 11.
In a preferred embodiment, the transparent adhesive layer 13 is selected from OCA glue layers.
The OCA glue layer has good light transmittance, and can reduce the loss of light in the conduction process between the base material 11 and the reflective film 12.

In an embodiment, the light source 2 is selected from LED lamps.
Specifically, the light source 2 may be selected from a point light source 2 or a linear light source 2 according to the size of the light emitting structure layer 1 and the arranged reflective pattern 121, and in some embodiments, the linear light source 2 may be composed of a plurality of point light sources 2 to illuminate a large area of the light emitting structure layer 1.
