Abstract
The utility model discloses a light guide film with conical UV (Ultraviolet) light guide bumps. The light guide film comprises a light guide film body; and more than one UV bump is fixedly arranged on the light guide film body in positions corresponding to the keys on a keyboard. The light guide film of the utility model, compared with the light guide film fabricated through the traditional process, is better to feel and better in light emission effect; the conical UV bumps are invisible after the light guide film emits light, so that the integrated effect of the light guide film cannot be affected; and simultaneously, the pressing force and the touch rate of an elastic piece cannot be affected; and the feeling of the light guide film is better than that of the light guide film with cylindrical UV bumps.
Description
Technical field
The utility model discloses a kind of light guiding film, particularly a kind of light guiding film that has conical UV leaded light salient point.
Background technology
The applied more and more of consumer electronics product in people's life that has keyboard along with mobile phone, notebook computer etc.; Its accessory industry has also obtained very big development, and wherein the keyboard light guiding film is exactly that mobile phone, notebook computer etc. have an important accessory in the consumer electronics product of keyboard.Light guiding film of the prior art can be provided with the leaded light salient point at the key position place usually; So that it is luminous more clear, bright; Mostly salient point on the conventional light guiding film is to adopt the UV adhesive curing to generate, and existing UV glue leaded light point shape all is columniform, and the salient point of this kind shape is processed on the light guiding film can both clearly see the leaded light point; Not only influence attractive in appearancely, and can influence the luminous of light guiding film.Existing UV leaded light point shape all is columniform; The salient point of this kind shape is processed on the light guiding film can both see leaded light point bright spot, and can hinder ray refraction and influence the luminous of light guiding film, also can influence the button feel; The shell fragment pressing force is risen, and the thoughts and feelings rate descends.
Summary of the invention
The clear shortcoming of seeing leaded light point of light guiding film ability to the above-mentioned band UV leaded light point of mentioning of the prior art; The utility model provides the light guiding film of the conical UV leaded light of a kind of new band salient point; It is provided with conical leaded light salient point on the light guiding film main body; Make light guiding film after lighting, be difficult for obviously seeing the leaded light point, and luminous even, effective.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of light guiding film that has conical UV leaded light salient point, light guiding film comprises the light guiding film main body, is fixed with more than one leaded light salient point corresponding to key position place on the keyboard on the light guiding film main body.
The technical scheme that its technical matters that solves the utility model adopts further comprises:
Described leaded light point adopts the UV adhesive curing on the light guiding film main body, to form.
The axial section of described conical leaded light salient point is an isosceles triangle, and the waist of isosceles triangle and the angle between the base are 5 ° ~ 30 °.
The top position of described conical leaded light salient point is that radius is the spherical crown of 0.3 ~ 0.8mm.
Described leaded light salient point bottom surface diameter is 2.5 ~ 4.0mm, and groove depth is 0.1 ~ 0.5mm.
The beneficial effect of the utility model is: the light guiding film in the utility model is compared with the light guiding film that traditional technology is made; Its feel is better; The illumination effect of light guiding film is better, after light guiding film is luminous, cannot see conical leaded light salient point, thereby can not influence the whole structure of light guiding film.Can not influence simultaneously pressing force, the thoughts and feelings rate of shell fragment, feel is better than the light guiding film of columniform leaded light point.
To combine accompanying drawing and embodiment that the utility model is further specified below.

Embodiment
Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection domain.
Please referring to accompanying drawing 1 to accompanying drawing 3; The utility model main body 1 is the film that square PC of a block length or TPU material are processed; Be fixed with more than one leaded light salient point 2 corresponding to key position place on the keyboard on the light guiding film main body 1; In the present embodiment, leaded light point 2 adopts the UV adhesive curing on light guiding film main body 1, to form.In the present embodiment, the axial section of conical leaded light salient point 2 is an isosceles triangle, and the waist of isosceles triangle and the angle between the base are 5 ° ~ 30 °, and the top position of conical leaded light salient point 2 is that radius is the spherical crown of 0.3 ~ 0.8mm.According to actual needs, it is 2.5 ~ 4.0mm that the leaded light in the utility model is put 2 bottom surface diameters, and depth of groove is 0.1 ~ 0.5mm.
Please referring to accompanying drawing 4; The utility model changes ray refraction through controlling conical leaded light salient point 2 angles; Accomplish that the invisible of leaded light point do not influence the luminous purpose of light guiding film with reaching, can not influence pressing force, the thoughts and feelings rate of shell fragment simultaneously, feel is better than columniform leaded light point 3.
Please referring to accompanying drawing 5, the processing mold main body 4 of the utility model is the square steel plate of a block length, puts 2 positions corresponding to leaded light on the light guiding film on the die main body 4 and has more than one cone-shaped groove 5.In the present embodiment, have surplus glue groove 6 in die main body 4 both sides, can be used for unnecessary UV glue is flowed away from surplus glue groove 6, die main body 4 both sides have pilot hole 7, when carrying out operations such as UV curing, can play the effect of assist location.
The utility model is adding man-hour, earlier with the UV glue spots to mould, the light guiding film of processing PC or TPU material again is put on the mould; Through UV glue being wipeed off with silk screen printing process; Unnecessary glue flows away from surplus glue groove 6, mould is put in the UV stove solidifies again, after 20 seconds mould is taken out; Leaded light point 2 promptly is solidificated on the main body 1; The light guiding film that PC or TPU material are processed is lifted down from mould, and the UV glue in the cone-shaped groove 5 on the mould just are transferred on the light guiding film that PC or TPU material process, and form the needed light guiding film that has conical leaded light salient point.
Light guiding film in the utility model is compared with the light guiding film that traditional technology is made, and its feel is better, and the illumination effect of light guiding film is better, after light guiding film is luminous, cannot see conical leaded light salient point, thereby can not influence the whole structure of light guiding film.Can not influence simultaneously pressing force, the thoughts and feelings rate of shell fragment, feel is better than the light guiding film of columniform leaded light point.
