Abstract
The utility model discloses a light guide structure of a touch switch panel. The light guide structure comprises a panel, and a PCB arranged inside the panel. A plurality of LED light sources are arranged on the PCB. The panel is provided with a light transmitting area. A light guide frame is disposed above the LED light sources, and is provided with light guide through holes corresponding to the LED light sources. A light diffuser is arranged above the light guide frame, and has a light incoming surface facing the light guide through holes and a light outgoing surface. The light incoming surface is provided with continuous V-shaped grooves or continuous waves. The light outgoing surface is a plane, and faces the light transmitting area. According to the light guide structure provided by the utility model, the light guide frame is arranged above the LED light sources, and provided with corresponding light guide through holes, so that most of the light of the LED light sources is input into the light incoming surface of the light diffuser and diffused by refraction, and the loss of the light sources is reduced; and then the light passes through the light outgoing surface and directly enters the light transmitting area, so that the light output by the diffuser is uniform.
Description
Technical field
The utility model relates to a kind of panel, specifically refers to a kind of soft-touch control panel light conducting structure.
Background technology
Switch is one of people's necessity for life, and along with people's living standard is more and more higher, not only the quality of switch is become better and better, and function is also more and more diversified.As soft-touch control, shake switch miscellaneous such as control switch etc. and arise at the historic moment, emerging of these products brings great convenience to our daily use.
Soft-touch control, it is a kind of emerging product of development in science and technology progress, it generally refers to a kind of switch on wall of application touch sensible chip principle design, it is the regeneration product of traditional mechanical push-key type switch on wall, can realize soft-touch control more intelligent, more convenient operation has the incomparable advantage of traditional switch, is popular a kind of decorative switch of current family product.In Modern Family due to decoration needs, the illuminating lamp of installing is more and more, accordingly also a lot of for controlling the switch on wall of these illuminating lamps, but no matter be traditional mechanical push-key type switch on wall or soft-touch control, existing switch mostly just plays to control and switches on and off function, do not have the function that can distinguish each luminous lamp switch, function singleness, can not meet the convenience demand of the modern life.
Therefore, for more flat-footed, know whether corresponding feature operation has successfully been carried out and avoided occurring misoperation, the button of increasing soft-touch control panel has designed in zones of different that several colors are backlight, function character functional character pilot light etc.The region that existing light guide structure normally shows needs at the panel upper cover of the button of switch panel is made as transparent or semitransparent material, in it, be provided with the light emitting source of light-emitting diode or bulb, rely on the luminous to assist printing or the image paster that illuminates panel surface of light emitting source, improve the display effect of button.In order to make full use of light source and uniformly light-emitting, soft-touch control panel button conventionally adopt circular light guide sheet by LED light irradiation on corresponding printing or image paster, then on panel, depict corresponding bright dipping region, then light guide sheet is affixed on to the back side of panel, when LED lamp is bright, form leaded light button.Yet the button so forming, because light guide sheet is installed and may do not aimed at, causes photochromic inhomogeneous; And because light guide sheet is hardware glass, during installation, hard contact easily damages.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of light guide structure of easy for installation, the uniform switch panel of leaded light is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of light guide structure of soft-touch control panel, comprise panel and be arranged on the PCB of panel inside, described PCB is provided with several LED light sources, described panel is provided with transparent area, it is characterized in that: described LED light source is provided with light guide support, described light guide support has the leaded light through hole corresponding with LED light source, described light guide support top is provided with scattering sheet, described scattering sheet be provided with one with leaded light through hole over against incidence surface and an exiting surface, wherein this incidence surface is provided with and is continuous V-shaped ditch or continuous wave shape wave, this exiting surface is a plane, described exiting surface and transparent area are over against setting.
As a kind of improvement of the present utility model, described transparent area is an annular, and reflective silver-colored paper is posted at the back side of described panel, and described reflective silver-colored paper is arranged in the inward flange of described annular.The light that LED light source sends enters incidence surface from leaded light through hole, after the effect of scattering sheet, by reflective silver-colored paper, by fully assembling from exiting surface light out and reflection mutually, finally from transparent area, penetrates, and strengthens the brightness of light, and light source utilance increases.
As a kind of improvement of the present utility model, between described PCB and panel, be provided with conducting foam.By hand touch panel, its signal senses conductive foam by panel, through the circuit of PCB inside and the components and parts turning circuit of PCB, plays control action.
The utility model has the following advantages and beneficial effect compared to existing technology:
1, light guide structure of the present utility model adopts light guide support is set on LED light source, and output corresponding leaded light through hole at light guide support, the light major part of LED light source is entered in the incidence surface of scattering sheet, when light passes through incidence surface, to spreading after light refraction, reduce light source loss; When by exiting surface, enter transparent area straightly, thereby make from scattering sheet light uniformly light-emitting out.
2, the light guide structure of soft-touch control panel of the present utility model only need depict the transparent area of different decorative pattern buttons on panel, and do not need to adopt the light guide sheet of different structure, light guide support is installed simple, and avoids existing light guide sheet owing to causing photochromic inhomogeneous and damage light guide sheet problem apart from light source near-far problem.
3. while producing, owing to there being conductive sponge, realizing panel and contact with miscellaneous part is soft, simple in structure, easy for installation.
