Abstract
The invention provides a PC (Poly Carbonate) light guide plate which is used for enabling the light to penetrate the mirror surface of the light guide plate formed by PC materials so as to enable the light guide plate to be uniformly pervious to light. The PC light guide plate comprises a PC mirror surface; a light incident area and a light transmitting area are formed on the front side and the back side of the PC mirror surface respectively; a plurality of spherical surfaces jointly form the light transmitting area, wherein the etching process is performed on the mirror surface to form the plurality of spherical surfaces. According to the PC light guide plate, the light can be well transmitted in a PC medium in any direction through the total reflection characteristic of the PC mirror surface on the light; the spherical surfaces are machined through the etching process and accordingly the light guide plate can be pervious to light in required places; the size and the distribution of the spherical surfaces are controlled within the required range and accordingly the light transmitted through the spherical surfaces can be uniform and friendly and light leak is not produced in an area free of spherical surface.
Description
Technical field
The present invention relates to LED lighting field, refer more particularly to a kind of PC light guide plate.
Background technology
At present, the touch-control icon of electronic product is substantially all to adopt LED lamp mode to illuminate, and the feature of this illumination mode is that optical processing ratio is easier to, optical efficiency is high, but shortcoming is can directly see LED illuminating source from the outside of lamp, easily forms dazzle, causes visual discomfort.And adopting the mode that LED lamp illuminates touch-control icon also to have problems, the light for example appearing is inhomogeneous, soft not, friendly not etc.
Summary of the invention
The defect existing for technique scheme, in order to address the above problem, the invention provides a kind of PC light guide plate, for the minute surface realization that light is made at PC material is penetrated, thereby make described light guide plate printing opacity even, it is characterized in that, comprising: PC minute surface, the tow sides of described PC minute surface are respectively arranged with light incidence section and photic zone; Wherein, described photic zone is provided with the spherical array that described PC minute surface use etch process is formed.
Above-mentioned PC light guide plate, is characterized in that, described spherical array is to consist of the concave spherical surface of relatively described specular surface or protruding sphere.
Above-mentioned PC light guide plate, is characterized in that, described light incidence section is provided with the indentation of " rice " font.
Above-mentioned PC light guide plate, is characterized in that, described light incidence section and described photic zone space on described PC minute surface distributes.
Above-mentioned PC light guide plate, is characterized in that, described spherical array can be arranged according to the needed shape of transmission region.
Owing to having adopted technique scheme, compared with prior art, the present invention can solve well light by the light guide plate with sphere and in light guide plate, transmits and appear problem.By PC minute surface, to the total reflection characteristic of light, make light can in PC medium, carry out well all directions propagation; By using etch process processing sphere can make light guide plate at the local printing opacity of needs; By controlling the size of sphere and being distributed in the scope of requirement, can guarantee that the light appearing by sphere is even, friendly, and not have the region of sphere there is no light leak.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present invention.
Fig. 2 is the structural representation of facing of the present invention.
Fig. 3 is back of the body TV structure schematic diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.Content of the present invention is to utilize the LED characteristics of luminescence, adopts the principle of indirect lighting, can improve the glare problem of reflection-type light source completely, and can realize the lighting requirement of multiple beam angle.
PC material minute surface has the total reflection physical characteristics of light, is to penetrate, and is reflected completely after light directive PC minute surface; The present invention becomes the mode of sphere, the total reflection of manual intervention PC minute surface by destroying PC mirror surface-shaped.
As Fig. 1, shown in Fig. 2 and Fig. 3, be respectively the vertical view of one embodiment of the present of invention, front elevation and rear view, provide a kind of PC light guide plate, for the minute surface of the light guide plate that light makes at PC material is realized, penetrates, thereby make described light guide plate printing opacity even, wherein, comprising: PC minute surface 1, the tow sides of described PC minute surface 1 are respectively arranged with light incidence section 2 and photic zone 3; Wherein, several spherical arrays 31 described photic zones of common formation that described minute surface use etch process is formed.As shown in Figure 1: the light that LED electroluminescent lamp sends enters into leaded light PC layer by light inlet region, the region (being photic zone) that light appears at needs simultaneously appears.
Preferably, as shown in Figure 2: described light incidence section is the indentation 21 of " rice " font.On the PC of light incidence section face, be washed into a meter font, to facilitate light to enter into PC layer from the die-cut facade of opening.Shown in Fig. 3, original smooth face is processed into recessed or protruding spherical array 31(and is commonly called as site simultaneously), light just can spill from sphere like this, by regulating the size of sphere and distributing, just can make the even bright dipping of light guide plate, described spherical array can be arranged according to the needed shape of transmission region.Described spherical array can be arranged in rectangle, circular or other regular polygons.In the place that there is no sphere, still realize the total reflection of light simultaneously.
In sum, owing to having adopted technique scheme, compared with prior art, the present invention can solve well light by the light guide plate with sphere and in light guide plate, transmits and appear problem.By PC minute surface, to the total reflection characteristic of light, make light can in PC medium, carry out well all directions propagation; By using etch process processing sphere can make light guide plate at the local printing opacity of needs; By controlling the size of sphere and being distributed in the scope of requirement, can guarantee that the light appearing by sphere is even, friendly, and not have the region of sphere there is no light leak
The foregoing is only this wherein preferred embodiment; not thereby limit the present invention's embodiment and protection domain wherein; to those skilled in the art; should recognize all utilization the present invention wherein instructions and diagramatic content being equal to of having done replace and the resulting scheme of apparent variation, all should be included in protection domain wherein.
