Preferably, this touch-control circuit is laid immediately on the lower surface of this touch eyeglass.This touch-control circuit of direct laying needs the technological means utilizing printed circuit lines or deposition circuit line, and these two kinds of means are ordinary skill in the art means, do not repeat them here.Direct laying circuit, just eliminates the carrier of this touch-control circuit, saves parts and space.
Preferably, this touch controlled key lighting device also comprises at least one light guide be arranged under this touch eyeglass, for the optical transport that sent by this at least one LED light source to this character zone.
Preferably, this at least one light guide paste be fixed on this touch eyeglass lower surface on.
Preferably, this at least one light guide is transparent membrane or transparent panel.
Preferably, this transparent membrane or transparent panel adopt pet material or polymethyl methacrylate materials or makrolon material or glass material.
Preferably, this at least one light guide is provided with some reflective spots, for changing the trend of light.
Preferably, this some reflective spot is be arranged on the concave point on this at least one light guide.
Preferably, this some reflective spot is silk-screen white ink point.
On the basis meeting this area general knowledge, above-mentioned each optimum condition, can be combined, obtain the preferred embodiments of the invention.
Positive progressive effect of the present invention is:
Touch controlled key lighting device of the present invention touches under eyeglass by LED light source and touch-control circuit being fixedly connected on, and can make light source and touch between eyeglass does not have miscellaneous part to stop, avoids field of illumination limited, and the space simultaneously taken is less and easily assemble.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the touch controlled key lighting device of a preferred embodiment of the present invention.
Detailed description of the invention
Provide present pre-ferred embodiments below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail, but therefore do not limit the present invention among described scope of embodiments.
Be illustrated in figure 1 the schematic diagram of the touch controlled key lighting device of a preferred embodiment of the present invention, this touch controlled key lighting device comprises touch eyeglass 1, touch-control circuit 2 and an at least one LED light source 3, this touch eyeglass 1 comprises a character zone 11, this touch-control circuit 2 is fixedly connected on the lower surface of this touch eyeglass 1, and this at least one LED light source 3 and this touch-control circuit 2 are fixedly connected on the lower surface of this touch eyeglass 1.The position of each parts of this touch controlled key lighting device is shown in order to clearer and be interconnected, the inside of mobile terminal illustrates by Fig. 1, it will be appreciated by those skilled in the art that the lower surface of one side in Fig. 1 above this touch eyeglass 1 and this above-mentioned touch eyeglass 1.
Wherein, this touch-control circuit 2 has two kinds of set-up modes.A kind of is that this touch-control circuit 2 is directly laid immediately on this touch eyeglass 1 lower surface by the technological means of printed circuit lines or deposition circuit line.Another kind of then be utilize a carrier that this touch-control circuit 2 is fixedly connected on the lower surface of this touch eyeglass 1, the carrier of this touch-control circuit 2 is selected to be ordinary skill in the art means, and common circuit carrier is as all applicable in circuit board etc.The method of direct laying eliminates the carrier of this touch-control circuit 2, saves parts and space, but relatively adopts the connected mode installation process of a carrier more complicated.
Further, this touch-control circuit 2 is fixedly connected on the lower surface of this character zone 11.Due to needs illumination is exactly this character zone 11, and this touch-control circuit 2 be fixedly connected on the lower surface of this character zone 11 after this at least one LED light source 3 be also fixed on this character zone 11 times, like this be arranged so that the nearest of this at least one LED light source 3 and this character zone 11, convenient this character zone 11 of illumination.
In order to more effective light be transferred to this character zone 11 uniformly, this touch controlled key lighting device also comprises at least one light guide 4 be arranged under this touch eyeglass 1, for the optical transport that sent by this at least one LED light source 3 to this character zone 11.Those skilled in the art are to be understood that, this at least one light guide 4 shown in Fig. 1 just illustrates the position that this at least one light guide 4 is arranged, shape and structure for this at least one light guide 4 is not restricted, and the effect that this at least one light guide 4 need can complete transmission light is all applicable.This at least one light guide 4 paste be fixed on this touch eyeglass 1 lower surface on.
In a preferred embodiment, this at least one light guide 4 is transparent membrane or transparent panel.This transparent membrane or transparent panel adopt pet material or polymethyl methacrylate or Merlon or glass.This different materials respectively has advantage, and can reach the effect of transmission light, can select according to actual needs.Wherein the cost of glass is lower, polymethyl methacrylate materials then has the excellent and outstanding resistance to ag(e)ing of good transparency, pet material has satisfactory mechanical property, rigidity is high, hardness is large advantage, and Merlon then has advantage that is heat-resisting, good processability.
This at least one light guide 4 being provided with some reflective spots, for changing the trend of light, thus internal structures different in mobile terminal can being adapted to.Schematically be shown in broken lines the trend of light in Fig. 1, the point of wherein light generation reflection is this some reflective spot, and understandably, this some reflective spot is only example and illustrates, the present invention is also unrestricted for its position specifically arranged.This some reflective spot can be the concave point be arranged on this at least one light guide 4 also can be silk-screen white ink point.These two kinds arrange all can play reverberation thus adjustment light the direction of propagation finally make illumination be mapped to the effect of this character zone 11.Wherein, this at least one light guide 4 arranges concave point to be needed to process in advance on this at least one light guide 4, and higher to the requirement of machining accuracy.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection scope of the present invention.
