Description

Structure improved illuminated keyboard

Technical field

The utility model is that a kind of light-emitting component that utilizes is connected with the power circuit of keyboard, sends light source and is covered with whole light-guide device by light-emitting component again, and make light-guide device be full of light, in order to do the illuminated keyboard that reaches night illumination and outward appearance visual effect.

Background of invention

The present luminescence technology that is applied to computer peripheral on the market, need shell or element (as: font on keyboard or the button) mostly with computer peripheral, be made into the element of tool light transmission, utilize back lighting device or cold light panel circuit again, control and send light source, and make whole computer peripheral luminous, reach the effect of illumination;

Only, described making back lighting device of above-mentioned located by prior art or cold light panel circuit cost are higher, also than power consumption, and the shell of computer peripheral or element also need special die sinking to make, or add the material of tool light transmission, except that increasing its cost on foot, its manufacture process is relative also more complicated, and usually is that This is what people generally disapprove of;

Therefore, how above-mentioned disappearance is forgone, be the place of the technical difficulties of this case utility model people institute desire solution.

Summary of the invention

The utility model provides a kind of structure improved illuminated keyboard, and its fundamental purpose is to utilize light-emitting component to send light source and be covered with whole light-guide device providing a kind of, and reaches the structure improved illuminated keyboard of illuminating effect.

Secondary objective of the present utility model is to be to provide a kind of to use the gap that light-guide device is arranged in surface of keyboard, and utilizes light-emitting component to send light source and be covered with whole light-guide device, in order to do to reduce the structure improved illuminated keyboard of cost of manufacture greatly.

Another purpose of the present utility model is to provide a kind of by utilizing light-emitting component to be connected with the power supply of keyboard, supplying light-emitting component required electric power, the structure improved illuminated keyboard of tool power saving effect;

A kind of structure improved illuminated keyboard comprises a keyboard, and this keyboard is the electronic installation of a connection computer, and is provided with a keyboard circuit; This keyboard circuit connection computer and sending controling instruction are to computer; Wherein also comprise a light-emitting component and a light-guide device;

This light-emitting component and light-guide device one end connect, and the light of light-guide device illumination is provided by this light-emitting component; And this light-emitting component is connected to the keyboard circuit of keyboard, utilizes the power supply power supply of keyboard circuit, and when KBPO, this light-emitting component also startup simultaneously emits beam;

This light-guide device is located at the gap of surface of keyboard, and can be with the light source that light-emitting component sent, and make light-guide device be covered with light via refraction and diffusion, the donating bond dish in arround during insufficient light, the font on the illuminated keyboard button.

Described a kind of structure improved illuminated keyboard, when dormancy or shutdown, it is not luminous that this light-emitting component also stops action.

Described a kind of structure improved illuminated keyboard, under park mode, this light-emitting component keeps light source.

Described light-emitting component and light-guide device can be arranged on the numeric keypad, for the numeric keypad illumination.

Embodiment

For the effect that makes convenient simple and direct understanding other characteristic contents of the present utility model of your auditor and advantage and reached can more manifest, with the utility model conjunction with figs., be described in detail as follows now:

See also Figure 1 and Figure 2, the utility model provides a kind of structure improved illuminated keyboard, and it is made of a keyboard 1, a light-emitting component 2 and a light-guide device 3;

Wherein, this keyboard 1 is the electronic installation for a connection computer 4, and is provided with a keyboard circuit 11; This keyboard circuit 11 is be responsible for to connect computer 4 and sending controling instruction to computer 4;

This light-emitting component 2 connects with light-guide device 3 one ends, and the light of light-guide device 3 illuminations is provided by this light-emitting component 2; And this light-emitting component 2 is connected to the keyboard circuit 11 of keyboard 1, utilize the power supply power supply of keyboard circuit 11, need not the effect that extra power supply has power saving concurrently, and this light-emitting component 2 is powered because of the power supply that utilizes keyboard 1, and when keyboard 1 start, this light-emitting component 2 also startup simultaneously emits beam, when keyboard 1 dormancy or shutdown, it is not luminous that this light-emitting component 2 also stops action, also can design keyboard 1 under park mode, still can keep light source;

This light-guide device 3 is gaps of being located at keyboard 1 surface, and the light source that light-emitting component 2 can be sent, and makes light-guide device 3 be covered with light via refraction and diffusion, donating bond dish 1 in arround during insufficient light, the font on illuminated keyboard 1 button;

Please consult Fig. 1 again and cooperate shown in Figure 3, in order to do be connected to computer 4 and energising when this keyboard 1 after, this light-emitting component 2 also emits beam simultaneously, conduct to light-guide device 3, by light-guide device 3 with light refraction and diffusion, make light-guide device 3 be covered with light, illuminate the surface of keyboard 1 and the font on the button, donating bond dish 1 is as illumination and increase the visual effect of outward appearance;

Please consult shown in Figure 4ly again, the utility model also can be implemented as follows: light-guide device 3 is located at around the surface of keyboard 1, and is set up several light-emitting components 2, to increase the brightness of light, make the brightness of its illumination brighter, wider general, the brightness multiplication that light-guide device 3 is thrown light on;

See also shown in Figure 5ly, the utility model also can be applicable to numeric keypad 5, be with light-emitting component 2 and light-guide device 3 be arranged in numeric keypad 5 around or spacious place, surface, for the font on the numeric keypad 5 illumination buttons, to reduce the number of times of input error;
