Abstract
The utility model relates to a light-guiding keyboard circuit which comprises a substrate, wherein the substrate is provided with a soft key; the substrate is a light-guiding substrate, and one side of the substrate is provided with a light source; and multiple light-guiding holes are also arranged on the substrate, and the light-guiding holes are arranged to form an annular light-guiding groove. According to the utility model, rays can be transmitted through the light-guiding substrate so as to eject through the light-guiding groove, the rays of a whole keyboard are uniform, and the consistency of the light-guiding groove is good; further, the shape of the light-guiding groove is changed through changing the arranging method of the light-guiding holes, the ejected shapes of the rays can be adjusted at will, therefore, the keyboard can adjust lighting effects at will; and the light quality of the light source is used to realize the illuminative uniformity of the keyboard, and an energy-saving effect is good.
Description
Technical field
The utility model relates to a kind of keyboard, but relates in particular to a kind of circuit of leaded light keyboard.
Background technology
Keyboard is applied to every field just more and more; Traditional keyboard structure generally comprises panel and button; There is power cable etc. inside, and there is a bigger defective in the keyboard of this structure, if promptly use the occasion light of keyboard darker; Then the operator is difficult for seeing clearly the sign on the keyboard, uses very inconvenience.
Some keyboard in the market; On the basis of original keyboard structure, increased lighting device, the most frequently used lighting device is the LED lamp, like Chinese patent 201120115655.5; Disclose a kind of keyboard of the LED of having lamp, the button of processing at transparent material has the LED lamp.This keyboard has solved the dark place and used the shortcoming of keyboard inconvenience, but has brought new problem, and is more like button on the keyboard; And be provided with the LED lamp under each button; Then LED lamp quantity is also more, in case it is more to light the electric energy of consumption, as the LED lamp only is set under a part of button; Then the LED lamp even portion of throwing light on is not high, causes the speck that light and shade differs on the keyboard.
The utility model content
The utility model provides a kind of energy-conservation and uniform leaded light keyboard circuit that throws light on for solving the prior art problem.
The technical scheme of the utility model is: a kind of leaded light keyboard circuit, comprise substrate, and this substrate is provided with soft button, and said substrate is the leaded light substrate, and a side of said substrate is provided with light source; Also be provided with a plurality of light-conductive holes on the said substrate, said light-conductive hole is arranged in the leaded light groove of annular.
The leaded light substrate conducts to whole keyboard with the light that the light source of a side sends; Through the leaded light groove of forming by light-conductive hole light is seen off then; Make that whole keyboard light is even, consistent, only need a light source can illuminate whole keyboard simultaneously, energy-saving effect is obvious.
As preferably, also be provided with keycap above the said button.
As preferably, the ring that said leaded light groove surrounds is similar with the shape of the bottom surface of said keycap, and the area of ring is greater than the bottom surface of said keycap.
As preferably, said light source is the LED lamp.
In sum, the utlity model has following advantage:
1, light conducts through the leaded light substrate, and is penetrated by the leaded light groove, and whole keyboard light is even, high conformity;
2, can further change the shape of leaded light groove through changing the arrangement mode of light-conductive hole, can adjust the shape that light penetrates arbitrarily, make keyboard that any adjustment illuminating effect can be arranged;
3, use the light quantity light source can realize the uniformity of keyboard illumination, good energy-conserving effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, substrate, 2, button, 3, the leaded light groove, 4, keycap, 5, light source.
Embodiment
With embodiment the utility model is described further below.
A kind of leaded light keyboard circuit, as shown in Figure 1, comprise substrate 1, this substrate 1 is provided with soft button 2, and button 2 tops also are provided with keycap 4, and substrate 1 is the leaded light substrate, and a side of substrate 1 is provided with light source 5, and light source 5 is the LED lamp; Also be provided with a plurality of light-conductive holes on the substrate 1, light-conductive hole is arranged in the leaded light groove 3 of annular, and the ring that the leaded light groove surrounds is similar with the shape of the bottom surface of keycap, and the area of ring is greater than the bottom surface of keycap.
When needs use keyboard, open light source 5, the light that light source 5 sends is conducted to whole keyboard by substrate 1, and when light ran into leaded light groove 3, through reflection or refraction, light penetrated from the upper surface of substrate, illuminates whole keyboard by the leaded light groove; When keyboard is finished using, close light source 5, further saves energy.
Wherein, the side-looking that substrate 1 is equipped with button 2 is a upper surface, otherwise then is regarded as lower surface.
Claims (4)
1. a leaded light keyboard circuit comprises substrate, and this substrate is provided with soft button, it is characterized in that: said substrate is the leaded light substrate, and a side of said substrate is provided with light source; Also be provided with a plurality of light-conductive holes on the said substrate, said light-conductive hole is arranged in the leaded light groove of annular.
2. according to the said leaded light keyboard circuit of claim 1, it is characterized in that: said button top also is provided with keycap.
3. according to the said leaded light keyboard circuit of claim 2, it is characterized in that: the ring that said leaded light groove surrounds is similar with the shape of the bottom surface of said keycap, and the area of ring is greater than the bottom surface of said keycap.
