Abstract
The utility model discloses a luminous backlight plate on a luminous keyboard. The luminous backlight plate is characterized in that the luminous backlight plate on the luminous keyboard includes a light guide plate which matches with long and short edges of the keyboard; the face of the light guide plate which is connected with the keyboard is the front face of the light guide plate, and the other face of the light guide plate is the back face of the light guide plate; one side of the long edge of the light guide plate is provided with an LED lamp strip, and LEDs on the LED lamp strip are staggered with keys; corresponding to each key area of the keyboard, the back face of the light guide plate is printed with combination points of high light refection circular points, and the points close to the lamps are small and sparse, and the points far away from the lamps are big and dense, and the points are arranged in proportion to form a luminous point face of the keys; the luminous point face is pasted with a reflecting film which has the same shape. The luminous keyboard is also disclosed. When a luminous device is unavailable, the key searching speed of specific keys is improved, the use efficiency is improved, the assembly is convenient and rapid, and the eyes are effectively protected. Besides, the luminous backlight plate is energy-saving and environmental-friendly.
Description
Technical field
The utility model relates to the keyboard technique field, is luminous backlight on a kind of illuminated keyboard and the technology of illuminated keyboard specifically.
Background technology
Traditional keyboard generally comprises keyboard sign frame, symbol keys and circuit board, this keyboard if do not turn on light, then can cause the difficulty of seeking button when using night, particularly without the bond seeking speed that affects special key under the lighting condition, reduce people's operating efficiency.
The utility model content
The purpose of this utility model provides a kind of easy to assembly, quick; and can when saving manufacturing cost, allow the in any case normal running of user at insufficient light; indefatigability; effectively protect eyes, luminous backlight and illuminated keyboard on the illuminated keyboard of energy-saving and environmental protection, power saving.
The purpose of this utility model is to be achieved through the following technical solutions:
Luminous backlight on a kind of illuminated keyboard, it is characterized in that: the luminous backlight on the described illuminated keyboard comprises the light guide plate that long limit and the minor face with keyboard is complementary, wherein the face that engages with keyboard of light guide plate is that light guide plate is positive, the another side of light guide plate is the light guide plate back side, side on the long limit of light guide plate is equipped with LED lamp bar, LED and button on the LED lamp bar are staggered, the light guide plate back side is little and thin corresponding to permutation and combination point and the point close to lamp that each key area on the keyboard is printed on high reflective round dot, point far away is large and close, sequence to scale the luminous point face that consists of button, post the identical reflectance coating of profile at the luminous point face.
Be printed on the fluorescent material oil of different colours corresponding to the luminous point face of wherein special key position.
Also be provided with the surrounding edge film around the described light guide plate.
LED lamp bar comprises pcb board, patch-type LED, patch-type resistance and the wire that circuit connects, and patch-type LED, patch-type resistance all are attached on the pcb board, and wire and pcb board welding also are provided with USB interface on LED lamp bar.
A kind of illuminated keyboard, it is characterized in that: described illuminated keyboard comprises keyboard sign frame, symbol keys and aforementioned luminous backlight, symbol keys is installed on the keyboard sign frame, fixedly mounts between luminous backlight and the keyboard sign frame.
The utility model compared with prior art has following beneficial effect:
1) the utility model has overcome the phenomenon that the prior art keyboard uses the difficulty of not turning on light to seek button the night, and the more effective bond seeking speed that has promoted without special key under the lighting condition improved service efficiency.
2) the utility model is easy to assembly, quick; and can when saving manufacturing cost, allow the user in the in any case normal running of insufficient light, indefatigability effectively protects eyes; more meet energy-saving and environmental protection, power saving requirement, be applicable to the use of all keyboards of computer realm.
Description of drawings
Fig. 1 is the luminous backlight board structure schematic diagram on the utility model illuminated keyboard;
Fig. 2 is the utility model illumination keyboard structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model LED lamp is described in detail.
Such as Fig. 1-2, luminous backlight on the utility model illuminated keyboard, comprise the light guide plate 1 that long limit and minor face with keyboard are complementary, wherein the face that engages with keyboard of light guide plate 1 is that light guide plate is positive, the another side of light guide plate is the light guide plate back side, side on the long limit of light guide plate is equipped with LED lamp bar 3, LED and button on the LED lamp bar 3 are staggered, the light guide plate back side is little and thin corresponding to permutation and combination point and the point close to lamp that each key area on the keyboard is printed on high reflective round dot, point far away is large and close, sequence to scale the luminous point face 2 that consists of button, post the identical reflectance coating of profile at the luminous point face.Be printed on the fluorescent material oil 4 of different colours corresponding to the luminous point face of wherein special key position, send the key set light source of different colours, be contained in the keyboard the inside and make that the user is very clear to find the own special key of commonly using.Wherein light guide plate 1 is ultra-thin PMMA light guide plate,
Around light guide plate 1, also be provided with the surrounding edge film.LED lamp bar 3 comprises pcb board, patch-type LED, patch-type resistance and the wire that circuit connects, and patch-type LED, patch-type resistance all are attached on the pcb board, wire and pcb board welding, and LED lamp bar just constitutes ultra-thin SMT LED lamp bar like this.Also be provided with USB interface on LED lamp bar 3, USB interface is connected on the pcb board.
The below describes principle in detail:
LED lamp bar: combined by lead-in wire, PCB, resistance, LED LED welding, light source sends the effect of luminous point.
The PMMA luminous plaque: main material is PMMA-MGSS (acryl) transparent material, plays LED lamp bar and gives out light source and carry out leaded light, printing opacity effect.
Bottom surface white ink luminous point: namely high reflective white ink luminous point consists of luminous point face 2, the light that comes out when LED lamp bar is during by the PMMA luminous plaque, when the light by sheet material arrives the bottom thoroughly, advance the light reflection during thoroughly to white point, the point intensity of reflected light is less, and large intensity of reflected light is also large, therefore, point close to light source is little and thin, and far away is large and close.
Multicolor phosphor printing ink: send out light time of different colours when certain button of needs, below its button, stamp respective color fluorescent material, send required color light.
