Hold the manufacture method of light button

The present invention provides a kind of manufacture method of holding the light button, You Zhiqi can be incorporated into the light-accumulating agent one silica gel push-button or its surface, make it absorb light at any time and hold light, and when the occasion of night or insufficient light, can send light spontaneously so that use the button person.

For be used in communication product (for example mobile phone, facsimile machine ... Deng) on button under the environment of night or insufficient light, still can clearly differentiate on the button numeral, literal or pattern so that the operation, be in button inside traditionally or the next door is provided with light-emitting diode (hereinafter to be referred as LED), make this LED when energize, can send light to illuminate numeral or the literal on the button.It is to make outer cover with the clear films elastomeric material that part is arranged at present, again in shroud floor in conjunction with button, make the light that defaults in keyboard can see through the button outer cover and illuminate literal or pattern symbol, and then provide under the environment of night or insufficient light and also can conveniently use.

As shown in Figure 2, known silica gel push-button, it is the button 1 that is shaped to space in the lower end has with the silica gel material of light-permeable, and 1 lower end of the button outside the space is combined with the conductive part made from electric conducting material 12 in this, and is printed with printing targets 13 such as literal, numeral or pattern in the upper surface of button 1; The position of desire installing button 1 is provided with LED3 and conductive junction point 21 in advance on circuit board 2 in addition, make when this button 1 is located on the circuit board 2, make its conductive part 12 corresponding to this conductive junction point 21, and make this LED3 be contained in the interior space of this button 1 below, when pushing this button 1, can make this conductive part 12 be contacted with this conductive junction point 21 and energising to transmit signal, this conductive part 12 broken away from conductive junction point 21 and cut off the power supply; These circuit board 2 set circuit provide this LED3 needed power supply in addition, it can be set at the light that sends that the LED3 power supply is provided automatically when communication product is in user mode, and makes light pass the button 1 of light-permeable and can be clear that its lip-deep literal, numeral or symbol.

The known button that another kind has illumination functions is as shown in Figure 3, it is provided with conductive part 12 corresponding to the conductive junction point on the circuit board 2 21 except the lower end at button 1, and its upper surface is printed on outside the printing target 13, in addition on button 1 circuit external plate 2 LED3 is set directly, the light that makes LED3 be passed to be sent behind the electric current directly illuminates the upper surface of button 1 and reaches the identification effect.

Yet the button that above-mentioned two kinds of tradition have lighting function all is that the light that utilizes LED to send reaches illumination functions, but installing LED is increased manufacture process loaded down with trivial details on circuit board, and manufacturing cost is higher; Again, though the power supply that LED consumed is few, remaining a kind of burden when using for a long time and in a large number, is to be at the disappearance of above-mentioned conventional keys ameliorator in addition with, the present invention.

Main purpose of the present invention is that light-accumulating agent directly is incorporated into silica gel push-button itself in that a manufacture method of holding the light button is provided, and makes it can absorb light having under the environment of enough light, discharges light when treating insufficient light again, to save the consumer of the energy.

A further object of the present invention is providing a kind of manufacture method of holding the light button, be by the surface that light-accumulating agent directly is incorporated into button, make it can absorb light having under the environment of enough light, discharge light when treating insufficient light again, and reduce manufacturing cost person according to this.

Based on this, the manufacture method of holding the light button provided by the present invention, be with light-accumulating agent add mix in the silica gel material of solid soft state after ejection formation again, so that whole button has the light action of holding, or light-accumulating agent is added in the silica gel of liquid state, by mode of printing silica gel is printed on keytop again, holds light button person with formation.

Other purposes of the present invention and function will more be understood after cooperating following graphic being described further, wherein:

Fig. 1 is for showing the section plan that holds the light press-key structure of the present invention;

Fig. 2 is the section plan of the press-key structure of the known light-permeable of demonstration;

Fig. 3 is for showing known section plan with press-key structure of illumination functions.

The manufacture method of holding the light button provided by the present invention, mainly be that light-accumulating agent directly is incorporated into silica gel push-button, make it can absorb light having under the environment of enough light, when treating insufficient light or dark environment, again the light that is absorbed is discharged, be beneficial to the usefulness of identification easy to use.It can have two kinds with the mode that light-accumulating agent is combined in silica gel push-button: wherein a kind of is that light-accumulating agent (being generally light-accumulating powder) is added in the silica gel material of soft solid state, after giving roll extrusion repeatedly repeatedly, roller make light-accumulating agent be incorporated in the silica gel material, then this silica gel material is shaped to button through mould, whole button after moulding this moment promptly has the light effect of holding, again on this button with other ink printing on the numeral, literal or symbol, so, can allow the user be easy to literal on the identification button by button itself produces illumination effect, numeral or symbol are easy to use; The below of this button then is provided with conductive part, and is provided with conductive junction point that should conductive part in circuit board, makes to be made this conductive part be contacted with conductive junction point and produce path after pushing this button.
