Embodiment 1
Energy-saving keyboard of computer, as shown in Figure 1-3, it includes pedestal 80, the keycap being set on pedestal 80 40 and setting
The scissor-shaped connecting rod of keycap 40 is used to support between keycap 40 in pedestal 80, further includes the Elastic Contact for being fixed on 40 bottom of keycap
Part 60, film circuit board 70 and multiple energy saving luminous modules 1, energy saving luminous module 1 are set to 80 upper surface of pedestal, thin film circuit
Plate 70 is set to 1 upper surface of energy saving luminous module, and resilient contact 60 is between energy saving luminous module 1 and keycap 40；Energy conservation hair
Optical module 1 includes light guide plate 10, with light incident surface 11, the bottom surface 12 and and bottom surface that intersect with light incident surface 11
12 opposite light-emitting areas 13, wherein multiple grooves 14 are arranged on bottom surface 12；The light that light source 20 is placed on light guide plate 10 enters
The side of reflective surface 11；Reflecting plate 30 is located at the bottom side and another side of light guide plate 10, for reflecting the light from light source.Instead
Bottom side and another side that plate 30 is located at light guide plate 10 are penetrated, for reflecting the light from light source.Each groove of light guide plate 10
14 there is 15. groove 14 of curved surfaces to be arranged in a stepped fashion according to the degree of approach of each groove and light source 20.By close to sources
20 groove 14 has lower height, and the groove 14 far from light source 20 has bigger height.The recess portion of light guide plate 10
14 each arc 15 can receive the light of equal quantities, enable light with identical brightness emission.The groove of light guide plate 10
14 be hemispheric.Each groove 14 is hemispheric.The light source is LED light emitting diode.The side of each groove 14 is
Arcwall face, each position receive the light of equivalent.
Energy saving luminous module 1 further includes light source 20, and light source 20 is emitted through the light that light incident surface 11 enters light guide plate 10
Line.In each groove 14 when reaching cambered surface 15 from the light of light source 20 on bottom surface 12, light is reflected by reflecting plate 30,
To advance towards light-emitting area 13.Meanwhile light concentrates at the curved surfaces 15 of each groove 14.The concentration of light increases
Overall brightness, therefore energy can be effectively saved.In addition, the construction of reflecting plate 30 prevents the light from light source 20 from leaded light
Plate 10 leaks.Light guide plate 10 full of the light from light source 20 keeps enough light.In a stepped fashion due to groove 14
Arrangement, the curved surfaces 15 of each groove 14 can receive the light of equal quantities.When the light for reaching curved surfaces 15 is reflected
And when guiding towards light-emitting area 13, they can be by energy saving luminous module 1 with identical brightness emission.
Two sides below each keycap 40 are equipped with a pair of of top retention portion 41；Multiple scissor-shaped connecting rods 50, each cut
Knife-like connecting rod 50 has a pair of of top hinge part 51 and a pair of of bottom hinge portion 52；Multiple resilient contacts 60, each bullet
Property contact 60 have a contact jaw 61；Film circuit board 70, by top, intermediate and bottom circuit layer composition；Pedestal 80 is set
There are multiple bottom corresponding with top retention portion 41 holding parts 81；Multiple energy saving luminous modules 1 are arranged in film circuit board
Between 70 and pedestal 80.The top hinge part 51 of scissor-shaped connecting rod 50 is fixed in the holding meanss of top first when assembling.
Then, resilient contact 60 is fixed on film circuit board 70 by glue, between keycap 40 and film circuit board 70.
Then, the bottom holding part 81 of pedestal 80 is buckled and is fixed below each keycap 40.The bottom hinge of scissor-shaped connecting rod 50
Part 52 is formed by piercing through film circuit board 70 and energy saving luminous module 1.
Each symbol 42 is carved on keycap 40 so that translucent effect is presented.It is illustrated by taking " D " key and " F " key as an example.
Each symbol be it is translucent, to be engraved on keycap.It it is known that two recess portions 14 at the light guide plate below D and F key
In, a recess portion 14 has the height bigger than another recess portion 14, because the arrangement of curved surfaces 15 of recess portion 14 is into a ladder
Mode.Light source 20 is located at the side of F key, and light is transmitted along from F key to the direction of D key.The light of light source 20 to optical plate 10 is incident
Surface 11 emits light.Then light reaches each curved surfaces 15 of the groove 14 at light guide plate bottom side 12 and is reflected instead
It penetrates.Then, the light of reflection advances through the membrane circuit board made of transparent or semitransparent material towards light emission surface 13
70.Light is finally issued from D and F key, is carved with translucent symbol 42 thereon.Therefore, key is illuminated with identical brightness.It is shining
In the process, the light from light source 20 concentrates at the curved surfaces 15 of each groove 14 at bottom surface of light guide plate 12.This light
Line concentrates the overall brightness for increasing module generation, therefore has been effectively saved energy.Further, since the groove 14 of light guide plate 10
It arranges in a stepped fashion, therefore the curved surfaces 15 of each groove 14 can receive the light of equal quantities.Therefore, light can be with
It is issued from key, is carved with translucent symbol 42 thereon, quantity is equal.
The keyboard is used for PDA, the keyboard structure of portable media player or any electronic equipment including keyboard.This
Outside, light source can be any color, and can be LED luminescence component.In the luminescence process of module according to the present utility model
In, the light from light source concentrates in the cambered surface of each groove.This light concentrates the overall brightness for increasing module generation,
Therefore it has been effectively saved energy.Moreover, because the groove of light guide plate is arranged in a stepped fashion, the curved surfaces of each groove
It can receive the light of equal quantities.Then, light is reflected and is guided to light-emitting area, there with identical brightness emission
Light.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
