Abstract

The utility model relates to the technical field of light transmission devices and especially relates to a light guide plate. The light guide plate comprises a substrate. The substrate comprises a light incidence face right opposed to a light source and receiving light emitted from the light source, a light guide face and a light extraction face respectively perpendicular to the light incidence face. The light guide face is provided with a plurality of light guide points which are distributed in an equidistant and spaced way. The light extraction face has a smooth and flat surface. The light guide points of the light guide plate are uniformly distributed. Great light extraction effects are achieved. Display effects of light guide illumination, decorative illumination, artistic illumination, television backlight sources, advertisements and indication signboards can be obviously improved.

Description

A kind of light guide plate
Technical field
The utility model relates to light conduction device technique field, relates in particular to a kind of light guide plate.
Background technology
Light guide plate design concept comes from the LCDs of notebook computer.Light guide plate adopts fluorescent light, CCFL, LED light source to see through light guiding points or the leaded light groove after calculating by optical principle, under reflective membrane (reflecting plate) and diffusion barrier effect, changes line source or pointolite into area source.For making light guide plate energy uniformly light-emitting, must be by various density, light guiding points not of uniform size, basic identical toward the efficiency of all directions reflection to guarantee light.The purposes of reflector plate (reflecting plate) is that the light reflection that bottom surface of light guide plate is revealed out returns in light guide plate, is used for improving the service efficiency of light, improves brightness.The effect of diffusion barrier is to make light more evenly softer.Being of wide application of light guide plate, as light-guide illumination, decorative lighting, artistic lighting, TV backlight, advertisement, sign board etc.The light guiding points skewness of existing light guide plate, bright dipping weak effect, thus affect the display effect of light-guide illumination, decorative lighting, artistic lighting, TV backlight, advertisement, sign board.
Summary of the invention
The utility model provides a kind of light guide plate for overcoming above-mentioned defect, the light guiding points of this light guide plate is evenly distributed, bright dipping is effective, can significantly improve the display effect of light-guide illumination, decorative lighting, artistic lighting, TV backlight, advertisement, sign board.
For achieving the above object, the utility model adopts following technical scheme.
A kind of light guide plate, comprise a substrate, described substrate comprise over against light source and receive the incidence surface of the light that described light source sends, respectively perpendicular to light guiding surface and the exiting surface of described incidence surface, described light guiding surface is provided with several light guiding points, several light guiding points equi-spaced apart are arranged, and described exiting surface smooth surface is smooth.
Wherein, the xsect of described substrate is curved, and the plane warping degree of described substrate is 0.05-0.25mm.
Further, the plane warping degree of described substrate is 0.2mm.
Wherein, described substrate is acrylic plate or PC plate.
Wherein, described substrate is transparent substrate.
Wherein, described incidence surface indentation.
Wherein, the outside surface of described substrate is coated with diaphragm.
Wherein, described diaphragm is release liners or release film.
The beneficial effects of the utility model are: a kind of light guide plate of the present utility model, comprise a substrate, described substrate comprises over against light source and receives the incidence surface of the light that described light source sends, respectively perpendicular to light guiding surface and the exiting surface of described incidence surface, described light guiding surface is provided with several light guiding points, several light guiding points equi-spaced apart are arranged, described exiting surface smooth surface is smooth, the light guiding points of this light guide plate is evenly distributed, bright dipping is effective, can significantly improve light-guide illumination, decorative lighting, artistic lighting, TV backlight, advertisement, the display effect of sign board.
Accompanying drawing explanation
With accompanying drawing, the utility model is described in further detail, but embodiment in accompanying drawing does not form any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of light guide plate of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, this is preferred embodiment of the present utility model.
Embodiment 1.
As shown in Figure 1, a kind of light guide plate of the present utility model, comprise a substrate, described substrate comprise over against light source and receive the incidence surface 1 of the light that described light source sends, respectively perpendicular to light guiding surface 2 and the exiting surface 3 of described incidence surface 1, described light guiding surface 2 is provided with several light guiding points 21, several light guiding points 21 equi-spaced apart are arranged, and described exiting surface 3 smooth surfaces are smooth.The light guiding points 21 of this light guide plate is evenly distributed, and bright dipping is effective, can significantly improve the display effect of light-guide illumination, decorative lighting, artistic lighting, TV backlight, advertisement, sign board.
The xsect of the substrate of the present embodiment is curved, the plane warping degree of described substrate is 0.05-0.25mm, further, the plane warping degree of the described substrate of the present embodiment is 0.1mm, plane warping degree is the light guide effect that 0.1mm can improve light guiding surface 2, the brightness of exiting surface 3 is improved, increase the utilization factor to light, practical.
The substrate of the present embodiment is acrylic plate or PC plate, and as a preferred technical scheme, the substrate of the present embodiment is acrylic board, and this sheet material is applied to the technology maturation of light guide plate, low price, and transmittance is good.
The substrate of the present embodiment is transparent substrate, and transparent substrate is applied to the technology maturation of light guide plate, is easy to production moulding, and reliability is high.
Incidence surface 1 indentation of the present embodiment, this setting can increase the ability that incidence surface 1 receives light source, makes light source see through to greatest extent incidence surface 1 and enters into light guide plate, can effectively improve light source utilization factor.
The outside surface of the substrate of the present embodiment is coated with diaphragm, this setting can prevent light guide plate in the process of transportation by dust or fingerprint pollution, prevent that light guide plate surface from forming dirt, thereby keep the good light guide effect of light guide plate, practicality is good.
The diaphragm of the present embodiment is release liners or release film, and as a preferred technical scheme, the diaphragm of the present embodiment is release film, utilizes release film as the technical maturity of diaphragm, the low price of release film, and protect effectively, reliability is high.s
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
