The utility model content
According to the technical problem of above-mentioned proposition, and provide a kind of induction light-penetration key.The utility model mainly utilizes light that light source launches in scattering, reflection and the refraction in induced key zone, thereby plays in the zone of appointment the evenly effect of printing opacity.
The technological means that the utility model adopts is as follows:
A kind of induction light-penetration key is characterized in that: comprise cover plate and sensor circuit plate;
Described cover plate is provided with a plurality of induced keys district, is respectively equipped with on the inner surface that described induced key district and described sensor circuit plate fasten be used to holding the light source I that is arranged on the described sensor circuit plate and light source groove I and the light source groove II of light source II;
Also be provided with reflector on the described sensor circuit plate, the area of described reflector is smaller or equal to the area in described induced key district.
As preferably, described light source I and light source II are the illuminated LED light-emitting diode of side, and the illumination zone of described light source I and light source II is α, and α satisfies: 0 °＜α＜90 °.
As preferably, the inner surface of described cover plate also fixedly has light-diffusing film, and described light-diffusing film is provided with through hole I and the through hole II corresponding with described light source groove I and light source groove II.
As preferably, described light-diffusing film is the PC plate of thickness 0.3-0.6mm.
Compare than prior art, the utlity model has following advantage:
The cover plate that the utility model provides adopts the PC+ABS plastic material, and to increase elastic strength and the tolerance level of cover plate, cover plate is provided with a plurality of induced keys district, and the induced key district can be arranged to the zone of different size according to the actual demand that makes electrical appliance; The inducing luminous principle of the sensor circuit plate that the utility model provides is: when hand touches the induced key district, cover plate is close on the sensor circuit plate, to change the electric capacity of the corresponding touch dish of sensor circuit, sensor circuit is sensed the action of button accordingly, makes light source luminescent; The light source that the utility model provides is the illuminated LED light-emitting diode of side, and the illuminated light illumination scope of side is subjected to blocking of cover plate, and the actual illumination scope according to actual needs, can change the color of light source between 0～90 °; It is irradiation luminous only to have mentioned two relative light sources in the utility model, and those skilled in the art are easy to expect that the light source more than 2 also can reach effect at the fixed area intraoral illumination by different arrangements, therefore also within protection range of the present utility model; The light-diffusing film that the utility model provides can make the more uniform transmission of light source, and the reflector that the utility model provides can make light stronger in reflex time brightness.
The utility model is achieved in that in operating process, finger touch induced key district, and changes in capacitance makes the LED lumination of light emitting diode.The light source of two correlation is through the scattering of light-diffusing film, pass through refraction and the through-hole wall on the light-diffusing film and (shown in the light path schematic diagrames of Fig. 5 to Fig. 8) such as bottom reflection of reflecting, refractions of the light source groove walls on cover plate and the cover plate again, reach irradiation area between two light sources in the induced key district that touches.
The utlity model has that induced key zone printing opacity is even, brightness is high, indicative advantage such as good, practical, the utility model can extensively be promoted in fields such as light-penetration keys for the foregoing reasons.
