Abstract
The utility model relates to a computer keyboard light-emitting board, solving the technical problems that a light-emitting computer keyboard is provided with a number of light sources, the cost is high and the power consumption is also high. In the technical scheme, the computer keyboard light-emitting board comprises a group of LED (light-emitting diode) light sources, a light guide plate and reflecting paper, wherein the LED light sources are uniformly arranged on one side end face of the light guide plate, the surface of the light guide plate is uniformly provided with a plurality of light guide points, the areas of the light guide points gradually increase along the irradiation direction of the LED light sources, clearances formed among the light guide points gradually reduce along the irradiation direction of the LED light sources, the reflecting paper has the same shape as the light guide plate and is compounded on the back face of the light guide plate, and the light guide points are arranged on a compounding surface of the light guide plate and the reflecting paper. The light-emitting board can be used in a light-emitting computer keyboard. The utility model has the advantages that the light-emitting board has a simple structure and is convenient to install and use, the number of the light sources is reduced, the cost and the power consumption are low, and light can be emitted uniformly.
Description
Technical field
The utility model relates to a kind of computor-keyboard luminous plaque, and the particularly a kind of leaded light point of led light source by uniform setting on the light guide plate that use makes that luminance brightness is tending towards uniform computor-keyboard luminous plaque on the light guide plate.
Background technology
The computer illuminated keyboard is the light source that is provided with by in the computor-keyboard housing at present, the hollowed-out translucent of symbol, letter or functional label by mark on the keyboard is realized, even in the prior art for realizing hollowed-out translucent, the brightness unanimity, the light source that is provided with in the computor-keyboard housing is need be in the computor-keyboard housing uniform be provided with a plurality of, the shortcoming of prior art is, it is many that light source is provided with quantity, the cost height, power consumption is big, light source position particularly is installed in the computor-keyboard housing is restricted, light source is provided with difficulty.
Summary of the invention
That quantity is set is many in order to overcome in the prior art computer illuminated keyboard light source, the cost height, and the technical deficiency that power consumption is big, the utility model discloses a kind of structure of computor-keyboard luminous plaque.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of computor-keyboard luminous plaque, comprise: one group of led light source, light guide plate and reflective sheeting constitute, described one group of led light source is in the uniform setting in a side end face of light guide plate, uniformly on the face on the described light guide plate be provided with one group of leaded light point, the area of described leaded light point increases gradually along the led light source direction of illumination, the gap that forms between the leaded light point dwindles structure gradually along the led light source direction of illumination, described reflective sheeting is identical with the light guide plate shape and be compounded on the back of light guide plate, and described leaded light point is arranged on the composite surface of light guide plate and reflective sheeting.
The beneficial effects of the utility model, simple in structure, easy to install, it is few that light source is provided with quantity, and cost is low, and power consumption is little, and is luminous even.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Accompanying drawing 1 is the utility model synoptic diagram.
Accompanying drawing 2 is an accompanying drawing 1A-A sectional view.
In the accompanying drawing, 1, led light source, 2, light guide plate, 3, the leaded light point, 4, reflective sheeting.
Embodiment
Referring to accompanying drawing, a kind of computor-keyboard luminous plaque comprises: one group of led light source, light guide plate and reflective sheeting constitute,
⑴, described one group of led light source 1 are in the uniform setting in a side end face of light guide plate 2.
Adopt the purpose of one group of led light source 1 to be, make the brightness of computor-keyboard luminous plaque satisfy the brightness of luminous computor-keyboard needs.
⑵ uniformly on 2 the face on, the described light guide plate be provided with one group of leaded light point 3, the area of described leaded light point 3 increases gradually along led light source 1 direction of illumination, and the gap that forms between the leaded light point 3 dwindles structure gradually along led light source 1 direction of illumination.
Leaded light point 3 adopts the purpose of said method setting to be, because led light source 1 makes light guide plate 2 whole shinny by light guide plate 2 leaded lights, because led light source 1 weakens gradually along the direction of illumination luminance brightness, make light guide plate 2 luminance brightness inconsistent, because the area of leaded light point 3 increases gradually along led light source 1 direction of illumination, increase by leaded light is put 3 reflective areas realizes the reflection enhancement to led light source 1, makes brightness unanimity on the light guide plate 2.
⑶, described reflective sheeting 4 is identical with light guide plate 2 shapes and be compounded on the back of light guide plate 2.
The purpose that reflective sheeting 4 is set is the front that the light of light guide plate 2 back is reflexed to light guide plate 2, improves the brightness of light guide plate 2 fronts, reduces electric quantity consumption.
⑷, described leaded light point 3 are arranged on the composite surface of light guide plate 2 and reflective sheeting 4.
Among the utility model embodiment, leaded light point 3 is the geometric configuration of circular, oval, rectangle or rule, is convenient to that leaded light is put 3 silk screens or other method is arranged on the light guide plate 2.
Claims (2)
1. computor-keyboard luminous plaque comprises: one group of led light source, light guide plate and reflective sheeting constitute, and it is characterized in that:
⑴, described one group of led light source (1) are in the uniform setting in a side end face of light guide plate (2);
⑵ the uniform one group of leaded light point (3) that is provided with on the face on, the described light guide plate (2), the area of described leaded light point (3) increases gradually along led light source (1) direction of illumination, and the gap that forms between the leaded light point (3) dwindles structure gradually along led light source (1) direction of illumination;
