In a further embodiment, described light emitting source is arranged near described vertical plane, and the light that described light emitting source is sent to be incided in described light guide structure by described vertical plane and is refracted into the end face of described keycap from described inclined-plane.
In a further embodiment, described inclined-plane is cambered surface or is made up of multiple concave spherical surface.
In a further embodiment, the described end face of described keycap is designed to atomized surface effect.
In a further embodiment, described end face has dermatoglyph.
In a further embodiment, described light emitting source is LED.
According to another aspect of the present utility model, provide a kind of electric equipment, comprise the luminous key device according to one side of the present utility model.
Embodiment of the present utility model provides a kind of luminous key device, and this luminous key device is installed simple, and integrated button and luminous deixis, make the operability of button improve, and reduces production cost.
Accompanying drawing explanation
Present general will only be described embodiment of the present utility model by example with reference to accompanying drawing, and wherein similar parts represent with identical Reference numeral, in accompanying drawing:
Fig. 1 is the perspective view of the luminous key device according to exemplary embodiment of the present utility model; And
Fig. 2 is the perspective view of the button of luminous key device according to exemplary embodiment of the present utility model.
Embodiment
Below with reference to exemplary embodiment, principle of the present utility model and spirit are described.Should be appreciated that describing these embodiments is only used to enable those skilled in the art understand better and then realize the utility model, and not limit scope of the present utility model by any way.
Fig. 1 and Fig. 2 is the perspective view of luminous key device according to exemplary embodiment of the present utility model and button respectively.With reference to Fig. 1,2, the luminous key device 100 according to exemplary embodiment of the present utility model is described.Luminous key device 100 according to exemplary embodiment can be installed on electrical appliance enclosure 2, to start the various function of electric equipment and to indicate the state of electric equipment.
The touch-switch 3 comprising button 1 according to the luminous key device 100 of embodiment of the present utility model and be positioned at inside button 1 and light emitting source 4, wherein button 1 is made up of transparent material and is comprised light guide structure 11.Can trigger touch-switch 3 when pressing keys 1, make light emitting source 4 luminous, light guide structure 11 is arranged so that the luminous energy of light emitting source 4 is refracted into button 1.
According to an embodiment of the present utility model, button 1 comprises keycap 12 integrally, contact 13 and light guide structure 11, and keycap 12, contact 13 and light guide structure 11 are made by transparent material.Light guide structure 11, contact 13 and keycap 12 are oppositely arranged, and in the embodiment shown in fig. 1, light guide structure 11, contact 13 are positioned at the left side of keycap 12 and are fixed on the bottom surface 122 of keycap 12.When the end face 121 of keycap 12 is subject to pressing, contact 13 moves along the direction that end face 121 is stressed, and trigger this touch-switch 3 with the touch-switch 3 touched in key device 100, this touch-switch 3 controls the circuit turn-on in key device.After circuit turn-on, light emitting source 4 (such as LED) works concurrent bright dipping, and light changes path via light guide structure 11 and makes keycap 12 shinny.
According to an embodiment, light guide structure 11 is at right angles triangular shaped generally and comprise vertical plane 112 and inclined-plane 111 as shown in Figure 1, 2, certain light guide structure 11 also can be other shapes, if the anaclasis that light emitting source 4 can be sent/reflex on button 1.Light emitting source 4 is arranged near the vertical plane 112 of light guide structure 11, in FIG, light emitting source 4 is positioned at light guide structure 11 (its vertical plane 112) below, and the light that light emitting source 4 is sent to be incided in light guide structure 11 by vertical plane 112 and is refracted into the end face 121 of keycap 12 from inclined-plane 111.Particularly, light upwards inside the incident inclined-plane 111 arriving light guide structure 11, is refracted to the end face 121 of keycap 12 afterwards, thus realizes the lighting function of button below vertical plane 112 by this chamfered inside.
In order to make luminescence more even, according to an embodiment, the inclined-plane 111 of light guide structure 11 is designed to cambered surface or is made up of multiple concave spherical surface, to increase the uniformity of reflection.Certainly, inclined-plane 111 also can be designed to the surface of other shapes, as long as there is bending radian in surface, can more disperse evenly reverberation.
The light sent to make keycap 12 is more evenly soft, and according to an embodiment, the end face 121 of keycap 12 can be designed to atomized surface effect, such as, arrange dermatoglyph etc. thereon, to strengthen diffuse effect.The surface of cloudy surface is coarse, diffuse reflection will occur when time above light is mapped to, all can not be dazzling viewed from which angle, and long-time viewing eyes can not be too tired.
According to another aspect of the present utility model, provide a kind of electric equipment (not shown), comprise above-mentioned luminous key device 100.Therefore the utility model just can realize key light emitting owing to not needing to arrange special light-emitting electronic devices around key device, and avoid, at inside electric appliance, special circuit is set to control corresponding light-emitting electronic devices, therefore to have production cost low for the utility model, can simplify the advantage of electric equipment circuit.Electric equipment of the present utility model can be ammeter, transformer, circuit breaker etc.
Give specification of the present utility model for the object illustrated and describe, but it is not intended to be exhaustive or be limited to the utility model of disclosed form.It may occur to persons skilled in the art that a lot of amendment and variant.
