Fig. 1 is the schematic diagram that a kind of pushbutton unit of one embodiment of the invention is applied in notebook computer, and wherein Fig. 2 is the partial schematic diagram of pushbutton unit illustrated in fig. 1, and Fig. 3 is the cut-away view of pushbutton unit illustrated in fig. 1.In the present embodiment, pushbutton unit 100 is suitable for being applied on the switch of a notebook computer 200, but is not limited thereto.In other embodiments, pushbutton unit 100 also can be applicable on the switch of general electrical appliance, as: button of the switch of light fixture, the switch of TV or elevator or the like and so on.Below be to be applied in explanation as an example on the notebook computer 200, but do not limit the scope that pushbutton unit 100 is used with this with pushbutton unit 100.
Please also refer to Fig. 1～Fig. 3, pushbutton unit 100 comprises that a light guide 110, internals 120, trigger a part 130 and an illuminating part 140.Light guide 110 has the optical surface 116 of an incidence surface 112, an exiting surface 114 and a relative exiting surface 114, and wherein optical surface 116 is a concaveconvex structure 116a.In the present embodiment, light guide 110 for example is a transparent light guide part, wherein to be suitable for entering light guide 110 from incidence surface 112 inner and in light guide 110 internal delivery for light, and the light that transmits light guide 110 in can be subjected to concaveconvex structure 116a reflection and interference on the optical surface 116.So, when light after exiting surface 114 outgoing of relative optical surface 116, the optical field distribution that is presented on the exiting surface 114 will present a kind of special light field Luminance Distribution, and wherein this optical field distribution is to decide according to the structure of concaveconvex structure 116a, and this part will describe in detail in follow-up paragraph.
Please continue 1～Fig. 3 with reference to figure, it is relative and keep one first apart from d1 to trigger part 130 and internals 120, and illuminating part 140 electric connection triggering parts 130.When internals 120 contact triggered parts 130, illuminating part 140 can provide a light L1 to incidence surface 112, wherein by the light L1 behind the incidence surface 112 in light guide 110 internal delivery and in exiting surface 114 outgoing.In the present embodiment, before internals 120 contacts triggered part 130, illuminating part 140 can have a second distance d2 with the plane of incidence 112 of light guide 110.In detail, push object 50 (finger that goes out as shown in Figure 3) when pushing light guide 110 when one, the internals 120 that then connect light guide 110 just can be followed interlock and contact and trigger part 130, and at this moment, illuminating part 140 just can provide light L1 to incidence surface 112.Need to prove, if adopt above-mentioned interlock mechanism, then second distance d2 can be less than first apart from d1, so can avoid when light guide 110 touches illuminating part 140 and cause internals 120 to touch triggering part 130, wherein first can drop between 0.45mm and the 0.65mm in fact, and second distance d2 can drop between 0.7mm and the 1mm in fact apart from d1.Yet when belonging to an elasticity light guide as if light guide 110, second distance d2 can be not less than first apart from d1, and this part will describe in detail in follow-up paragraph.
After light L1 entered light guide 110 by incidence surface 112, light L1 can be in light guide 110 internal delivery.And when light L1 transmits in light guide 110 inside, because the concaveconvex structure 116a on the optical surface 116 can reflect and interfere light L1, therefore, light is after exiting surface 114 outgoing, and its optical field distribution that is presented on exiting surface 114 will be different with the concaveconvex structure 116a different design of employing.For example, when concaveconvex structure 116a is when designing as the shown a kind of regular concaveconvex structure of Fig. 4 A (as: wavy shaped configuration), like this then can make outgoing present the systematicness cloth of secretly showing the score in the optical field distribution of the light L1 of exiting surface 114, wherein this systematicness cloth of secretly showing the score for example is the optical field distribution of bright dark bright dark and so on systematicness, wherein the pattern of this optical field distribution can be the bright dark fringe of concentric circles of ripples shape, or the bright dark fringe of many diffuseds, Fig. 4 B then presents the partial schematic diagram of the bright dark fringe of ripples shape after being pressed for pushbutton unit.Otherwise, when if concaveconvex structure 116a is design as the shown a kind of irregular concaveconvex structure of Fig. 4 C, like this then just can make outgoing present the scrambling cloth of secretly showing the score in the optical field distribution of the light L1 of exiting surface 114, wherein this scrambling cloth of secretly showing the score for example is the striped of bright dark bright dark and so on scrambling.
Need to prove, recess among the concaveconvex structure 116a is normally corresponding is bright fringes in the striped, and the dark fringe in the normally corresponding striped of the protuberance among the concaveconvex structure 116a, therefore, suitably the pattern of design concaveconvex structure 116a can make the light pattern that is presented on the exiting surface 114 more diversified.In addition, when transmitting in light guide 110 inside owing to light L1, its brightness that is presented on the optical field distribution on the exiting surface 114 just can be along with light L1 is far away more and weak more in the distance of light guide 110 internal delivery.Therefore, the optical field distribution that is presented on the exiting surface 114 is secretly showed the score the pattern of cloth except meeting has above-mentioned systematicness secretly shows the score cloth or scrambling, its bright rays also can be along with light L1 is far away more and weak more in the distance of light guide 110 internal delivery to specific luminance with dark line, and then present a kind of special optical field distribution, for example be the undulatory bright dark fringe of water, and bright dark fringe can be far away more and dark more to specific luminance with centre distance.
Based on as can be known above-mentioned, the pushbutton unit 100 of present embodiment is when being pressed, illuminating part 140 can be activated and provide light L1 in light guide 110, and because the surface that light guide 110 contacts with internals 120 presents a concaveconvex structure 116a, therefore, just can be subjected to the influence (reflection and interference) of this concaveconvex structure 116a at the light of light guide internal delivery, and make the optical field distribution of outgoing on exiting surface 114 present a kind of special light pattern (systematicness cloth of secretly showing the score as the aforementioned, the irregular cloth of secretly showing the score, the bright dark fringe of the concentric circles of ripples shape, or the bright dark fringe of many diffuseds).
In one embodiment, if light guide 110 itself is when belonging to the elasticity light guide, then second distance d2 can be not less than first apart from d1, or can be zero (incidence surface 112 that is light guide 110 can contact this illuminating part).In other words, second distance d2 and first belongs to unlike material and produces not start mechanism and the time there is no specific relativeness at light guide 110 apart from d1.Specifically, when pushing object 50 (finger that goes out as shown in Figure 3) when pushing light guide 110, because light guide 110 itself has elasticity, therefore, the position that light guide 110 is pressed just can present depression, and the internals 120 that connect light guide 110 this moment just can be subjected to the influence of this deformation and and then interlock and touch and trigger part 130.Similarly, when internals 120 touched triggering part 130, illuminating part 140 also can provide light L1 to incidence surface 112.
In addition, above-mentioned pushbutton unit 100 also can comprise a minute surface blooming piece 150, is configured on the exiting surface 114.In the present embodiment, minute surface blooming piece 150 can will reflect from light from outside, and at the light L1 of light guide 110 internal delivery behind outgoing exiting surface 114, still can present aforesaid systematicness secretly the show the score optical field distribution of cloth of cloth or scrambling of secretly showing the score by this minute surface blooming piece 150.
What deserves to be mentioned is that when above-mentioned light guide 110 was employing transparent light guide part, in order to improve the overall brightness of the optical field distribution of light L1 on exiting surface 114, the material of internals 120 can be to adopt the non-light-transmitting materials or the internals of reflective material.Thus, just be difficult for penetrating internals 120 and cause optical loss at the light L1 of light guide 110 internal delivery.In other words, if internals 120 are to adopt non-light-transmitting materials or reflective material, can improve the overall brightness that is presented on the optical field distribution on the exiting surface 114.
In sum, pushbutton unit of the present invention has following advantage at least.At first, the surface design that light guide is connected with internals is the surface of a concaveconvex structure, so as to reflection and the light of interfering, thereby make the optical field distribution of outgoing behind exiting surface present systematicness cloth or the scrambling cloth of secretly showing the score of secretly showing the score in the light guide internal delivery.So, when pushbutton unit was pressed, its surface just can present abundant light, so as to attracting consumer's attention.In addition, by internals being adopted light tight or during material that can be reflective, except the brightness that can avoid light loss in light guide inside, and improve further outside the overall brightness of the optical field distribution on the exiting surface, also can avoid the beholder can directly watch the element of pushbutton unit inside, and influence attractive in appearance.
