Through adopting above-mentioned technical scheme, utilize the condensing lens, concentrate the light that scatters on daytime and follow and jet out with reflective membrane vertically direction for the reflection of light luminance of reflective membrane on daytime improves, and the light is less when night, and difficult production is concentrated, avoids the light of reflection to concentrate and produces the condition of dazzling, thereby lets other people can be daytime and night all show the seeing of eye, thereby in time avoids.

Preferably, the concave points are filled with long afterglow materials.

Through adopting above-mentioned technical scheme, the long afterglow material in the concave point can let the partial light of daytime refraction be absorbed to send the light when night, so that instruct for the position that does not have the light source, thereby let other people in time see and in time avoid.

Preferably, the cross section of the light-gathering piece is semicircular, and the diameter of the light-gathering piece is flush with one end, far away from the base layer, of the reflecting prism.

Through adopting above-mentioned technical scheme, spotlight spare cross-section can effectually let light refract for the semicircle form to let light to the gathering of reflection of light prism direction, reach the effect of spotlight.

Preferably, the condenser lens is provided with fixed protrusion at one end of the diametric plane, and the side of the fixed protrusion is attached to the reflecting prism.

Through adopting above-mentioned technical scheme, fixed protruding quilt that can let the condensing lens better is fixed to let better with light gathering and reflection of condensing lens.

Preferably, the base layer is vapor-plated with a metal reflective coating.

Through adopting above-mentioned technical scheme, the reflection of light cladding material on the basic unit can let the space between the condensing lens be filled to let light by better reflection.

Preferably, the light gathering member and the reflecting prism are both made of silicon-based materials.

By adopting the technical scheme, the silicon-based material has higher light transmittance and is more suitable for refraction.

Compared with the prior art, the beneficial effects of the utility model are that: the light that scatters around daytime utilizes the condensing lens to gather together, then reflects and goes out along the direction of perpendicular reflective membrane to reach the effect of spotlight, reach the effect of reinforcing the reflective membrane reflection of light on daytime, utilize long afterglow material to absorb to remain to give out light night simultaneously with some light, reach the effect of fluorescence suggestion at night.

Reference numerals are as follows: 1. a base layer; 2. a protective layer; 3. concave points; 4. a transition section; 5. a condenser lens; 6. a one-way see-through layer; 7. a long afterglow material; 8. a reflecting prism.

Detailed Description

In the following description of the present invention, it is understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention and to simplify the description, but not to indicate or imply that the indicated device or element must have a specific direction, be constructed and operated in a specific direction, and thus should not be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the long afterglow light-gathering reflective film comprises a base layer 1, wherein a protective layer 2 is arranged on the base layer 1, a plurality of concave points 3 are arranged on the base layer 1, reflective prisms 8 are arranged on two sides of each concave point 3, a light-gathering piece is arranged between every two adjacent reflective prisms 8, one end, away from the base layer 1, of each reflective prism 8 is provided with a one-way perspective layer 6, long afterglow materials 7 are filled in the concave points 3, the cross section of each light-gathering piece is semicircular, and the diameter of each light-gathering piece is flush with one end, away from the base layer 1, of each reflective prism 8.

This product is applicable to the outside reflection of light of plane class product, paste this product during the use on products such as signboards or warning sign, when the daytime, because shining of sunshine, the whole luminance of environment promotes, the reflection of light that the reflective membrane produced this moment can be covered by light on every side basically, cause the insufficient condition of warning to appear, and this product can pass through the refraction reflection with scattered light, the final perpendicular direction with the reflective membrane of gathering is followed and is shined out, abundant utilization light scattered characteristics on every day, strengthen the reflection of light luminance of this product, thereby let also can be higher than the luminance of other positions on daytime still, thereby reach the effect of warning.

This product is when partial light enters into protective layer 2, utilize the refracting index of protective layer 2 to be greater than the air, make the incident angle can be greater than the angle of departure when light enters protective layer 2, make light take place the refraction, light after the refraction continues to remove then penetrates condensing lens 5, because the refracting index of condensing lens 5 is greater than protective layer 2, make the light incident angle be greater than the angle of departure, light continues to pass condensing lens 5 after that, when light is getting into changeover portion 4, the refracting index of changeover portion 4 is greater than condensing lens 5 in the same way, the incident angle is greater than the angle of departure once more again, finally light is when getting into reflecting prism 8, change direction once more, thereby make light adjust to and wear out protective layer 2 after keeping the vertical state with the reflective membrane, utilize the light gathering of scattering daytime then along the direction perpendicular with the reflective membrane to shoot out, make the reflective membrane brighter daytime, and can be with the light reflection of reflective membrane perpendicular twice again at night, reach more conspicuous, resume the effect of normality evening.

The long afterglow material 7 is absorbed after contacting with light, and the light in the long afterglow material 7 is emitted when the night arrives, so that the reflective film is illuminated, and the warning effect can be realized under the condition of no light source. Condensing lens 5 sets up in diametric plane one end and is provided with fixed arch, and fixed arch side and 8 laminating of reflecting prism utilize fixed arch to fix condensing lens 5 to let the reflective membrane more stable when using. The light that vertical illumination that has plated the metal reflection of light cladding material reflector layer can be better on base layer 1 reflects back. The light-gathering piece and the reflecting prism 8 are both made of silicon-based materials, and the silicon-based materials have better stability and can better keep the reflecting effect of the reflecting film.
