Description
Technical field
The invention provides a kind of circuit board structure capable of self-illumination, You Zhike is for producing light with the board structure of circuit to the outside projection,, can concentrate for the light side direction to be projeced in the circuit board to being provided with illuminating part by the circuit board private side, improve the luminous usefulness of circuit board.
Background technology
At present, in the epoch of this scientific and technological progress, electronic product has brought one of people environment easily, yet, most Introduced cases electronic product all needs button to carry out literal, the input of numeral or instruction, as mouse, keyboard or the rocking bar that recreation was suitable for, light gun etc., but along with making rapid progress of product, button also needs to come change at different demands, for example from the employed button of the keyboard of early stage desktop computer to the employed button of notebook computer, its difference is just suitable big, what emphasize because of notebook computer is light, thin, short, little, so its employed button just can't be as the keyboard of desktop computer, and the characteristic that must meet above-mentioned notebook computer is come change.
Moreover, button as mobile phone originally can't be luminous, but people can use mobile phone at rather dark place, but can't be pressed into required button accurately this moment, be so that there is manufacturer to propose improvement at this problem, make button can send light source to be convenient for people to use, see also shown in Figure 13, this illuminated keyboard is for being provided with keypad portion A, back lighting device B, its keypad portion A is for being provided with circuit board A2 above base plate A1, and circuit board A2 is provided with the light-emitting component A21 of transmitting illuminant down, and above circuit board A2, be provided with plastic film A3 with flexible member A31, and base plate A1 is connected with button A5 up through connect mechanism A4, is provided with the light guide plate B1 of back lighting device B again below the base plate A1 of keypad portion A, and light guide plate B1 below is provided with reflecting plate B2 again.
The light-emitting component A21 of this circuit board A2 is transmitting illuminant down, light source passes the light guide plate B1 that is radiated at back lighting device B behind the base plate A1, and light guide plate B1 is to reflecting plate B2 with light source projects, after utilizing reflecting plate B2 reflection source, pass light guide plate B1 and keypad portion A more in regular turn, making the button A5 at keypad portion A top have light manifests, but because of the group constitutive element part of keypad portion A and back lighting device B many, thickness after then causing keypad portion A and back lighting device B combining increases, when using, reality still has many disappearances, as:
(1) the light-emitting component A21 of circuit board A2 is after downward transmitting illuminant, through reflection, refraction repeatedly, just light is projected to button A5 place at last, yet after light source is through reflection repeatedly, to cause mixing and the brightness of the light source that detracts, causing the loss of luminous energy of light, it is also relatively poor that the light at button A5 place manifests effect.
(2) keypad portion A adds that the thickness behind the back lighting device B increases, and can't be suitable for, meet light, thin, short, the little design requirement of electronic installation, will cause the keyboard thickness of electronic installation also can thicken along with increasing of element.
(3) the base plate A1 of keypad portion A is provided with a plurality of axle beds, and each axle bed need pass circuit board A2 and just can assemble for connect mechanism A4, cause to be provided with a plurality of perforation thoroughly on the circuit board A2, then the locus that configuration can be set reduces in a large number, design and make comparatively difficult, consuming time and take a lot of work.
(4) if be provided with a plurality of films in the circuit board A2 of keypad portion A, and power supply circuits, signal circuit be set respectively on the different surfaces of film, though can be used to solve the disappearance of insufficient space, but need repeatedly process because of a plurality of films multiple circuit is set, cause manufacturing cost greatly to go up.
Therefore, above-mentioned commonly using in the employed circuit board of illuminated keyboard, because of having problems and disappearance, this is the inventor and the target place of being engaged in this journey improvement that the dealer desires most ardently.
Summary of the invention
The objective of the invention is to the technical problem that solve the existing employed circuit board light of illuminated keyboard weak effect, make difficulty, cost is high.
For achieving the above object, the invention provides a kind of circuit board structure capable of self-illumination, comprise circuit board and line layer, this circuit board is that two substrates of light-permeable material are made, and be provided with more than one the evenly light guide section of transmitted ray on the circuit board, and uprightly be provided with more than one illuminating part, for throwing light in circuit board for side direction, outwards throw via light guide section again, and illuminating part is between circuit board and electrically conduct in the configuration of line layer, and this line layer is for being fixedly arranged in the circuit board.
This circuit board is oppositely arranged composition by light-permeable material and two different substrates of thickness, and the top substrate layer gauge can be thinner than down laminar substrate (also can make top substrate layer be slightly thicker than down laminar substrate), and be provided with in than thick substrate in lower floor can be for the light guide section of the even transmission of light more than one, and can uprightly be provided with more than one illuminating part, and illuminating part can be the light-emitting diode (LED) of surface adhesion type, adopts vertical type and is arranged at down in the laminar substrate.
Technique effect of the present invention is, by the illuminating part lateral direction light emission, is outwards throwed by light guide section to concentrate light in the circuit board again, reduces light loss phenomenon, but and the luminous brightness of gain circuitry plate.By the side direction projection source is set in circuit board, effectively promotes the circuit board light and manifest effect.
