Abstract
The invention discloses a light emitting keyboard without a light guide plate. The light emitting keyboard comprises a keyboard upper cover, a keyboard middle board, a keyboard bottom plate, a key conductive film, a key module and an LED (Light-Emitting Diode) light emitting lamp strip. The keyboard middle board is made of a light transmittable material and has light transmittance of 10 percent to 90 percent; at least one LED light emitting lamp strip is arranged on the back of the keyboard middle board. The light emitting keyboard has a simple structure; atomization lamp bulbs are utilized to carry out first-step diffusion on light emitted by a light source and then the light is subjected to second-step diffusion by the light transmittable keyboard middle board; by matching of first-step diffusion and second-step diffusion, a function of an original light guide plate is realized; under the condition of not increasing assemblies, the aim that the keyboard uniformly emits light is fulfilled while the light guide plate is omitted, and thus, manufacturing cost of the light emitting keyboard is greatly reduced and t industrial batch production of the light emitting keyboard is facilitated.
Description
Technical field
The present invention relates to a kind of keyboard, specifically a kind of illuminated keyboard without light guide plate.
Background technology
Keyboard is current modal input unit, is used in various different electronic product, such as mobile phone, remote controller, personal digital assistant, PC etc.These electronic products likely use under circumstances, such as, in the occasion of insufficient light.For allowing user still can accurate pressing keys in the occasion of insufficient light, and there is the appearance of illuminated keyboard.
Current illuminated keyboard, primarily of plate, keyboard board, button conducting film, button, light guide plate and LED composition in keyboard top cover, keyboard.Button to be arranged in keyboard on plate, in keyboard, plate is arranged between keyboard top cover and keyboard board, under plate, a light guide plate is installed in keyboard, light guide plate side is provided with LED, utilize LED as light source luminescent, utilize light guide plate that the light of light source is carried out scattering, light is uniformly distributed in light guide plate, and then realize the luminescence of keyboard.
The realization of above-mentioned luminescence, needs light guide plate, and light guide plate cost is high, and then makes the holistic cost of illuminated keyboard higher.
Summary of the invention
The object of the invention is to overcome existing illuminated keyboard need to use light guide plate, thus make the deficiency that its cost is higher, a kind of illuminated keyboard without light guide plate is provided.
For achieving the above object, the technical solution adopted in the present invention is:
Without an illuminated keyboard for light guide plate, include plate in keyboard top cover, keyboard, keyboard board, button conducting film, key-press module, LED luminescent lamp strip.
Push-button light guiding film is installed on keyboard board;
In keyboard, plate is placed on button conducting film;
In keyboard, plate is made up of light-permeable material, and light transmittance is 10%-90%;
In keyboard, plate has several by key mapping;
In keyboard, the back side of plate is provided with at least one LED luminescent lamp strip;
LED luminescent lamp strip comprises substrate and is evenly located at several LED lamp bead on substrate, and substrate is installed on the back side of plate in keyboard, and LED lamp bead is fragrant lamp pearl, and meanwhile, LED lamp bead is also to lateral bending 90 degree;
Key-press module Guan County is pressing in key mapping, and key-press module comprises key switch and is arranged on the keycap on key switch, and key switch is conflicted with button conducting film through switch bit and coordinated;
Keyboard top cover is sleeved in keyboard on plate, and after being connected and fixed with keyboard board, by solid for plate holder in keyboard between keyboard top cover and keyboard board.
Preferred as one, LED luminescent lamp strip is two, and both are parallel, is installed in top and the bottom of back in keyboard respectively, and the LED lamp bead on LED luminescent lamp strip does 90 degree of bendings towards plate central authorities in keyboard.
Structure of the present invention is simple, fragrant lamp pearl is utilized to carry out first step diffusion to the light that light source sends, then via plate in the keyboard of light-permeable, second step diffusion is carried out to light again, being coordinated by both, realizing the function of former light guide plate, when not increasing assembly, while eliminating light guide plate, complete the object of keyboard uniformly light-emitting, greatly reduce the manufacturing cost of illuminated keyboard, the big batchization being conducive to illuminated keyboard is produced.
Accompanying drawing explanation
Fig. 1 is structural blast schematic diagram of the present invention.
