Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.The utility model is carried out below in conjunction with attached drawing
Detailed description.
As depicted in figs. 1 and 2, a kind of light guiding film for improving light utilization efficiency provided by the utility model, including fold set successively
Protective layer 1, adhered layer 2, reflecting layer 3, optical waveguide layer 4 and light shield layer 8, the utility model is additionally provided with through the protective layer 1, institute
The facial expression hole 11 of adhered layer 2, the reflecting layer 3 and the optical waveguide layer 4 is stated, facial expression hole 11 is described to accommodate the light source in the external world
Light shield layer 8 covers the facial expression hole 11；The optical waveguide layer 4 is provided with diffusing reflection area 41, and the periphery of the optical waveguide layer 4 is provided with use
In the application of anti-leakage layers 5 for preventing that the light of light source from dissipating.
The facial expression hole 11 of the utility model is surrounded on light source, when light source luminescent, due to light shield layer 8 and application of anti-leakage layers 5 not
Printing opacity, therefore when light contacts are to light shield layer 8 or application of anti-leakage layers 5, can all reflect so that light is only capable of through optical waveguide layer 4
Projected by diffusing reflection area 41, so as to improve the utilization rate of light.
In addition, as depicted in figs. 1 and 2, in the present embodiment, the optical waveguide layer 4, which is sticked, key-course 6, the control
Preparative layer 6 is provided with the Jie Guang areas 61 of controllable opening and closing, and Jie Guang areas 61 are used to cover diffusing reflection area 41.The Jie Guang areas 61 are by silica gel system
Into.When pressing Jie Guang areas 61, silica gel is extruded to both sides under pressure, so that light can be projected by Jie Guang areas 61；
After Jie Guang areas 61 are unclamped, under the action of silica gel does not have pressure, gradually recover deformation and Jie Guang areas 61 are covered, so as to allow light
No longer project.The utility model button can just be shone when pressed, so as to allow people can be easily by the setting of shading region
Know whether oneself effectively pushes button.
In the present embodiment, the protective layer 1 is made of foam, when the utility model is connected with light source, to rise
