Abstract
The utility model discloses a light guide membrane applied in a cell-phone, which comprises a membrane made of transparent material, wherein a plurality of light guide convex points are arranged on the membrane from sparse to dense according to the direction away from a light source. The light guide membrane has smart and reasonable design, makes lights well-distributed through the reasonable distribution of the light guide convex points, and has low production cost and reliable quality.
Description
Technical field
The utility model relates to light guiding film, particularly a kind of light guiding film that is applied on the mobile phone.
Background technology
At present, the remote keying of mobile phone or electrical equipment at night can both be luminous, except button is to adopt the Noctilucent material, generally is to conduct and realize by LED lamp direct irradiation, cold light film or light guide plate are set under button.If mobile phone will adopt the luminous scheme of LED light irradiation, generally to use the 6-8 LED lamp, also to be equipped with resistance, the cost height, and light is inhomogeneous; If can reduce the use of LED lamp with the light guide plate scheme, but light guide plate is thicker,, on ultrathin mobile phone, be difficult to adopt because the mobile phone inner space is limited; Cold light film is the cost costliness then, and complex circuit designs is not easy to apply.
The utility model content
The purpose of this utility model is, provides that a kind of design is ingenious rationally, production cost is low and can make the equally distributed light guiding film of light.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of light guiding film, it comprises a diaphragm of being made by transparent material, is provided with a plurality of leaded light salient points on this diaphragm, described leaded light salient point by away from the direction of light source by dredging to close setting;
Described leaded light salient point can be the salient point of erose salient point or regular shape;
Described leaded light salient point is the sphere salient point;
Described diaphragm is provided with the light source hole of two ccontaining light sources;
Described leaded light salient point can be established a completely whole diaphragm or only be located at the local location of this diaphragm.
The beneficial effects of the utility model are: the utility model design is ingenious rationally, by the reasonable distribution of leaded light salient point, make light even, and its production cost is low, reliable in quality.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a leaded light schematic diagram of the present utility model.
Embodiment
Embodiment: see Fig. 1 and Fig. 2, a kind of light guiding film of the utility model, it comprises a diaphragm 1 of being made by transparent material, is provided with a plurality of leaded light salient points 2 on this diaphragm 1, described leaded light salient point 2 by away from the direction of light source 4 by dredging to close setting; Described leaded light salient point 2 can be the salient point of erose salient point or regular shape; Described leaded light salient point 2 is the sphere salient point; Described diaphragm 1 is provided with the light source hole 3 of two ccontaining light sources 4; Described leaded light salient point 2 can be established a completely whole diaphragm 1 or only be located at the local location of this diaphragm 1.
When using light guiding film, light is come by light source 4 direct projections, by being distributed in the leaded light salient point 2 on the diaphragm 1, light up reflects, thereby illuminate the button of being located at light guiding film top, leaded light salient point 2 by away from the direction of light source 4 by dredging to close distribution, make the leaded light salient point 2 on whole the diaphragm 1 light fully can be refracted to each position of button, make light even, soft.
As described in the utility model embodiment, with other light guiding film of the same or similar structure of the utility model, all in the utility model protection domain.
Claims (5)
1, a kind of light guiding film, it comprises a diaphragm of being made by transparent material, is provided with a plurality of leaded light salient points on this diaphragm, it is characterized in that: described leaded light salient point by away from the direction of light source by dredging to close setting.
2, light guiding film according to claim 1 is characterized in that, described leaded light salient point can be the salient point of erose salient point or regular shape.
3, light guiding film according to claim 2 is characterized in that, described leaded light salient point is the sphere salient point.
4, light guiding film according to claim 1 is characterized in that, described diaphragm is provided with the light source hole of two ccontaining light sources.
