Preferably, this touch-control circuit is laid immediately on the lower surface of this touch eyeglass.Directly lay the technological means that this touch-control circuit need to utilize printed circuit lines or deposit the circuit line, these two kinds of means are ordinary skill in the art means, do not repeat them here.Directly lay circuit, just saved the carrier of this touch-control circuit, saved parts and space.
Preferably, this touch controlled key lighting device also comprises and is arranged at least one light guide that light under this touch eyeglass, that be used for will this at least one led light source sending transfers to this character zone.
Preferably, this at least one light guide is pasted on the lower surface that is fixed on this touch eyeglass.
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, be provided with some reflective spots for the trend that changes light on this at least one light guide.
Preferably, these some reflective spots are the concave point that is arranged on this at least one light guide.
Preferably, these some reflective spots are silk-screen Liquid Paraffin ink dot.
On the basis that meets this area general knowledge, above-mentioned each optimum condition, but any combination namely get each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is:
Touch controlled key lighting device of the present utility model is by being fixedly connected on led light source and touch-control circuit under the touch eyeglass, can be so that do not have miscellaneous part to stop between light source and touch eyeglass, avoided the field of illumination limited, the less and easy assembling in the space that takies simultaneously.
Description of drawings
Fig. 1 is the schematic diagram of the touch controlled key lighting device of a preferred embodiment of the present utility model.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, with the detailed description the technical solution of the utility model, but therefore the utility model is not limited among the described scope of embodiments.
Be illustrated in figure 1 as the schematic diagram of the touch controlled key lighting device of the utility model one preferred embodiment, this touch controlled key lighting device comprises that one touches eyeglass 1, a touch-control circuit 2 and 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.For the position of clearer each parts that this touch controlled key lighting device is shown with interconnect, Fig. 1 illustrates the inside of portable terminal, the one side that it will be appreciated by those skilled in the art that this touch eyeglass 1 top among Fig. 1 is the lower surface of above-mentioned this 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 directly is 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 to utilize a carrier that this touch-control circuit 2 is fixedly connected on the lower surface of this touch eyeglass 1, it is ordinary skill in the art means that the carrier of this touch-control circuit 2 is selected, and common circuit carrier such as circuit board etc. are all applicable.The method of directly laying has been saved the carrier of this touch-control circuit 2, has saved parts and space, but has relatively adopted 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.Because what need 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 also be 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 be more effective light to be transferred to this character zone 11 uniformly, this touch controlled key lighting device also comprises and is arranged at least one light guide 4 under this touchs eyeglass 1, transfer to this character zone 11 for the light that will this at least one led light source 3 sends.Those skilled in the art are to be understood that, at least one light guide 4 of shown in Fig. 1 this just illustrates the position that this at least one light guide 4 arranges, shape and structure for this at least one light guide 4 is not restricted, and it is all applicable that 4 need of this at least one light guide can be finished the effect of transmission light.This at least one light guide 4 is pasted on the lower surface that is fixed on this touch eyeglass 1.
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 both 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 good and outstanding resistance to ag(e)ing of good transparency, pet material has the advantage that satisfactory mechanical property, rigidity are high, hardness is large, advantage heat-resisting, good processability that Merlon then has.
Be provided with the some reflective spots for the trend that changes light on this at least one light guide 4, thereby can adapt to internal structures different in the portable terminal.Schematically be shown in broken lines the trend of light among Fig. 1, wherein the point of light generation reflection is this some reflective spots, is appreciated that ground, and these some reflective spots only are the example explanation, and the utility model is also unrestricted for its concrete position that arranges.The concave point that these some reflective spots can be arranged on this at least one light guide 4 also can be silk-screen Liquid Paraffin ink dot.Thereby these two kinds arrange the equal direction of propagation that can play reverberation adjustment light and finally make illumination be mapped to the effect of this character zone 11.Wherein, at this at least one light guide 4 concave point is set and need to does in advance processing at this at least one light guide 4, and having relatively high expectations to machining accuracy.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
