By the structure of above-mentioned first light guide plate 35 and the second light guide plate 36, the first color beam B1 and the second color beam B2 is made to be able to carry out total reflection respectively in the first light guide plate 35 and the second light guide plate 36, and when the first color beam B1 is projected to the first light guide section 351 or the second light guide section 352, the first color beam B1 is up projected to the first bright dipping region 3011A or the 3rd bright dipping region 3011C.When the second color beam B2 is projected to the 3rd light guide section 361 or the 4th light guide section 362, the second color beam B2 is up projected to the second bright dipping region 3011C or the 3rd bright dipping region 3011C.
The internal structure of the film switch circuit 302 of following explanation key-press module 30.Film switch circuit 302 is arranged between supporting bracket 31 and multiple button 301, produces multiple push button signalling in order to be triggered by multiple button 301, and film switch circuit 302 to comprise on one wiring board 3021, separator 3022 and once wiring board 3023.Upper wiring board 3021 has multiple upper contact 3021A, separator 3022 is positioned at the below of wiring board 3021, and separator 3022 has the multiple separator perforate 3022A corresponding to multiple upper contact 3021A, when film switch circuit 302 is touched, corresponding upper contact 3021A stretches into corresponding separator perforate 3022A.Line plate 3023 is positioned at the below of separator 3022, has corresponding to the multiple lower contact 3023A of multiple upper contact 3021A and forms multiple key switch 3024 with multiple upper contact 3021A and multiple separator perforate 3022A.
Light-reflecting portion 37 is arranged at the below of the second light guide plate 36, the second color beam B2 is up projected and again enters the second light guide plate 36 in order to reflect the second color beam B2, to promote the utilization rate of the second color beam B2.In this preferred embodiment, light-reflecting portion 37 is a reflector.
The luminous situation of following explanation lighting keyboard 3.When lighting keyboard 3 is operated by driving, first light-emitting component 33 and the second light-emitting component 34 produce the first color beam B1 and the second color beam B2 respectively, wherein, because luminous circuit board 32 is between the first light-emitting component 33 and the second light-emitting component 34, first color beam B1 and the second color beam B2 is intercepted respectively, with the situation avoiding the first color beam B1 and the second color beam B2 that mixed light occurs by luminous circuit board 32.Next, the first color beam B1 is entered in the first light guide plate 35 by projection, and the first color beam B1 carries out total reflection in the first light guide plate 35 inside.When the first color beam B1 is projected to multiple first light guide section 351, multiple first light guide section 351 destroys the total reflection of the first color beam B1 and guides the first color beam B1 up to project, the first color beam B1 is made to be projected to multiple first bright dipping region 3011A through film switch circuit 302, now, the multiple first bright dipping region 3011A on button cap 3011 can produce the effect sending ruddiness.
On the other hand, the second color beam B2 is entered in the second light guide plate 36 by projection, and the second color beam B2 carries out total reflection in the second light guide plate 36 inside.When the second color beam B2 is projected to multiple 3rd light guide section 361, multiple 3rd light guide section 361 destroys the total reflection of the second color beam B2 and guides the second color beam B2 up to project, the second color beam B2 is made sequentially to be projected to multiple second bright dipping region 3011B through the first supporting bracket perforate 311, first light guide plate 35 and film switch circuit 302, now, the multiple second bright dipping region 3011B on button cap 3011 can produce the effect sending blue light.Wherein, be projected in the process of the second bright dipping region 3011B in the second color beam B2, second color beam B2 is by means of only the first light guide plate 35, and in the first light guide plate 35, do not carry out total reflection, therefore the second color beam B2 is by the impact of the first color beam B1, and the situation of mixed light can not be there is with the first color beam B1.
Get back to the first light guide plate 35.The the first color beam B1 not being projected to multiple first light guide section 351 continues in the first light guide plate 35 and carries out total reflection.When the first color beam B1 is projected to multiple second light guide section 352, multiple second light guide section 352 destroys the total reflection of the first color beam B1 and guides the first color beam B1 up to project, and makes the first color beam B1 be projected to multiple 3rd bright dipping region 3011C through film switch circuit 302.As in the second light guide plate 35, the second color beam B2 not being projected to multiple 3rd light guide section 361 continues in the first light guide plate 35 and carries out total reflection.When the second color beam B2 is projected to multiple 4th light guide section 362, multiple 4th light guide section 362 destroys the total reflection of the second color beam B2 and guides the second color beam B2 up to project, and makes the second color beam B2 sequentially be projected to the 3rd bright dipping region 3011C through the second supporting bracket perforate 312, first light guide plate 35 and film switch circuit 302.When the second color beam B2 leaves film switch circuit 302 and does not arrive the 3rd bright dipping region 3011C, there is mixed light situation and form one the 3rd color beam B3 in the second color beam B2 and the first color beam B1, therefore multiple 3rd bright dipping region 3011C then sends the light of the 3rd color.In this preferred embodiment, the 3rd color beam is violet beam.
