Description
Technical field
It the utility model is related to LED lamp materials processing technology field, and in particular to a kind of light conducting plate structure.
Background technology
Light guide plate is acryl/PC plate material using optical grade, and then using has high reflectivity and the not high-tech of extinction
Skill material, light guiding points are stamped in the acryl plate bottom surface of optical grade with UV screen printing technologies.Utilize optical grade acrylic plate
Material draws the stop in optical grade acryl plate surface from the light that lamp issues, when light is mapped to each light guiding points, reflection
Light can be spread toward all angles, then destroyed conditioned reflex and projected by light guide plate front.By various densitys, not of uniform size lead
Luminous point, can make light guide plate uniformly light-emitting.The purposes of reflector plate is returned in light guide plate in the light reflection for exposing bottom surface, for improving
The service efficiency of light.
Light guide plate is the significant components in LCD backlight module, its design with manufacture be backlight module key technology it
One.Light guide plate major function is guiding radiation direction, controls the uniformity of brightness, its performance directly determines guide-lighting module
Performance.And light guide plate surface micro-structure and the angle to backlight module beam projecting, determine the uniformity of beam projecting.
The widely used guide-lighting plate shape of in the market is mostly rectangle, and the micro-structure under distributed rectangular makes because parameter is less
It must process more simple.Under traditional distributed rectangular, the form that micro-structure shows is the uniformity of dot matrix, at this time light guide plate
It is relatively low.
Utility model content
The purpose of this utility model is that the defects of being directed to the prior art and deficiency, there is provided a kind of simple in structure, design is closed
Reason, light conducting plate structure easy to use.
To achieve the above object, the technical solution adopted in the utility model is：It includes light conducting plate body and guide-lighting groove；Institute
The reflective surface for the light conducting plate body stated is evenly equipped with some guide-lighting grooves, and some leaded light grooves are set up in parallel；The guide-lighting groove by V grooves and
Arc groove is formed, and arc groove is provided with the top of V grooves；The arc groove is made of side by side some waveform grooves.
Preferably, the spacing X of two neighboring waveform groove is 0.04~0.06mm.
Preferably, the spacing Y of two neighboring leaded light groove is 0.5~0.7mm.
Preferably, the radius of the arc groove is 0.13~0.18mm.
Preferably, the length and width of the light conducting plate body is 40~60mm.
The operation principle of the utility model is：Light in light guide plate during any transmission, through with guide-lighting board interface
Or micro-structure surface as some waveform grooves is had an effect, absorbed, reflected, reflected, the radiation flux hair that light carries
Changing, according to the change of radiation flux, and the adjustment of the horizontal spacing X and longitudinal pitch Y of waveform groove, light guide plate reach compared with
High uniformity.
With the above structure, what the utility model produced has the beneficial effect that：A kind of light guide plate described in the utility model
Structure, using the micro-structure of waveform groove, is greatly improved the uniformity of light guide plate, the uniformity of light guide plate up to 84%, this
Utility model has the advantages that simple in structure, setting is reasonable, low manufacture cost.

Referring to such as Fig. 1 --- shown in Fig. 3, present embodiment adopts the following technical scheme that：It includes light conducting plate body 1
With guide-lighting groove 2；The reflective surface of the light conducting plate body 1 is evenly equipped with some guide-lighting grooves 2, and some leaded light grooves 2 are set up in parallel；It is described
Guide-lighting groove 2 be made of V grooves 3 and arc groove 4, the top of V grooves 3 is provided with arc groove 4；The arc groove 4 is by some waveforms
Groove 5 is formed side by side.
Preferably, the spacing X of two neighboring waveform groove 5 is 0.04~0.06mm.
Preferably, the spacing Y of two neighboring leaded light groove 2 is 0.5~0.7mm.
Preferably, the radius of the arc groove 4 is 0.13~0.18mm.
Preferably, the length and width of the light conducting plate body 1 is 40~60mm.
The operation principle of present embodiment is：During light arbitrarily transmits in light guide plate, warp and light guide plate
Micro-structure surface as interface or some waveform grooves 5 is had an effect, and is absorbed, reflected, reflected, and the radiation that light carries is led to
Amount changes, according to the change of radiation flux, and the adjustment of the horizontal spacing X and longitudinal pitch Y of waveform groove 5, light guide plate
