Optionally, as shown in figure 14, Figure 14 illustrates for the 4th structure of the switching circuit board of luminous button of the present invention
It is intended to, switching circuit board 15 also includes extension 1533, and extension 1533 is from the second side of switch portion 151 towards away from incident side wall
15411 direction extension but do not link with outer frame 154, in this way, the first light R1 is transmitted to after switch portion 151, also along the
Two straight line L2 are transmitted to extension 1533, to provide light to transparent keycap 11.
First light R1 via being just transmitted to the second connecting piece 1532 or extension 1533 after the first connecting piece 1531, but by
Understand damping capacity in transmission of the first light R1 on the first connecting piece 1531 and the second connecting piece 1532 or extension 1533, because
And energy of the first light R1 on the second connecting piece 1532 or extension 1533 can be than the energy on the first connecting piece 1531
It is also small, so, separate laying on the connecting piece 1532 of switching circuit board 15 second of the present embodiment or the surface of extension 1533
There are a plurality of scattering points 17, when part the first light R1 touches any one scattering point 17, the part the first light R1 can be from
Second connecting piece 1532 or extension 1533 depart from and travel up to transparent keycap 11, use raising transparent keycap 11 in distance
The luminous intensity of light source 161 remotely, improves the uniformity of keycap Integral luminous effect.
Further, on the second connecting piece 1532 or the surface of extension 1533 a plurality of scattering points 17 laying spacing or cloth
If area is can adjust according to light source 161 apart from length, i.e., close to the adjacent of light source 161 in a plurality of scattering points 17
The distance that scattering point is spaced apart be more than a plurality of scattering points 17 in away from light source 161 adjacent scattering point be spaced apart away from
From, and the laying area in a plurality of scattering points 17 close to the scattering point of light source 161 is less than in a plurality of scattering points 17 away from light
The laying area of the scattering point in source 161, i.e. will be laid apart from light source 161 more remote place on the surface of the second connecting piece 1532
More intensive or area bigger scattering point 17.For example, as shown in figure 5, having a plurality of scatterings on the second connecting piece 1532
At point 17, (1) closer light source 161, two neighboring scattering point 17 is spaced first apart from D1;(2) apart from light source 161 farther out
Place, two neighboring scattering point 17 is spaced second distance D2;Wherein, first is more than second distance D2 apart from D1, that is, second
The surface of connecting piece 1532 can a plurality of scattering points 17 of non-equidistant placement, but be not limited, for example, as shown in figure 4, second connects
The surface of knot part 1532 can also be placed equidistant a plurality of scattering points 17, to meet the illumination effect of the demand of transparent keycap 11.
Fig. 7-Figure 10 is referred to, Fig. 7 is the sectional view of the illuminated keyboard of the second embodiment using luminous button of the present invention,
Fig. 8 is the component decomposition map of the second embodiment of luminous button of the present invention, and Fig. 9 is the switching circuit board for the luminous button that Fig. 8 shows
Figure is found with the component groups of light source circuit board, Figure 10 is the light conduction of the switching circuit board of luminous button second embodiment of the present invention
View.The present embodiment and the Main Differences of first embodiment are:Light source circuit board 16 is located under switching circuit board 15
Side, light source 161 is protruding upward from light source circuit board 16, to make the access switch circuit board 15 of exiting surface 1611 of light source 161 enter
In unthreaded hole 1541, framework 14 extends the top of light source 161, and to provide masking to light source 161, such user can not see this
The upper surface of light source 161, and reduce user it is observed that the light that light source 161 is scattered upward, so more additional keys are checked and regulated
Body aesthetic property.
In addition, light source circuit board 16 also have board support portion 163, board support portion 163 be located at switch portion 151 with
Between bottom plate 12, to eliminate the gap between bottom plate 12 and switch portion 151, and switch portion 151 is fixedly supported, it is ensured that transparent keycap
11 can successfully trigger switch portion 151.As shown in figure 8, board support portion 163 may also extend into the first connecting piece 1531 and bottom
Between plate 12, and between the second connecting piece 1532 and bottom plate 12, the first connecting piece 1531 and second is so more securely supported
Connecting piece 1532, also can ensure that transparent keycap 11 can successfully trigger switch portion 151.

View field 121.Linkage part 13 forms linkage part view field 122 in the projection of bottom plate 12.Incidence hole 1541 is in bottom plate
12 projection forms incidence hole view field 123.Linkage part view field 122 enters in transparent keycap view field 121
Unthreaded hole view field 123 is outside transparent keycap view field 121.In this way, there is sufficient space the lower section of linkage part 13, with printing opacity
When keycap 11 moves up and down relative to bottom plate 12, it is to avoid linkage part 13 is interfered with light source 161, and then may insure key
Cap 11 keeps enough up and down motion strokes, and can reduce the height of integral keyboard simultaneously.Certainly, said switching circuit plate and light
The setting relation of source circuit plate is also available in the illuminated keyboard of above-mentioned first embodiment.
In summary, each luminous button has exclusive light source and switching circuit board in illuminated keyboard of the invention.
Switching circuit board has incidence hole and connecting piece, wherein, incidence hole is to receive the light that light source is sent, and connecting piece conducts
The light that incidence hole is received, uses and provides light to the transparent keycap of luminous button, so the illuminated keyboard of the present invention needn't
Light guide plate is set and volume can be reduced, and the light of the transparent keycap receiving of plurality of luminous button is close, and can make to light
Brightness in keyboard between transparent keycap reaches unanimity.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Various corresponding changes and deformation, but these corresponding changes and deformation can be made according to the present invention by knowing those skilled in the art
The protection domain of appended claims of the invention should all be belonged to.
