Description
Technical field
The utility model is related to illumination optical technical field, more particularly to a kind of transparent PMMA light guide plates.
Background technology
Modernized society in fast development, with the development of science and technology various high end materials with having also appeared in people
Life around.Light guide plate has been applied to the fields such as light fixture, advertisement screen as a kind of optical material.The main work of light guide plate
With the scattering direction for being guiding light, brightness is improved.But when light source is projected from light fixture or advertisement screen in direct-injection type, because light is derived from
The lighting angle problem of body, can produce dazzle, give people to bring sense of discomfort.All it is mostly at present to use side to solve glare problem
Enter formula light-emitting mode, will light source be arranged on light guide plate both sides, in this way, mixed light can be caused insufficient, produce firefly phenomenon.Together
When, existing light guide plate generally existing reflex, i.e. light are reflected rather than exiting surface is mapped to from the exiting surface of light guide plate, are led
Brightness is caused to decline.Additionally, the fixed installation work of existing light guide plate is complicated, need additionally to realize fixing peace by fixture
Dress, in this way, fixture and the exiting surface and incidence surface directly contact of light guide plate, are easily damaged exiting surface and incidence surface, influence is led
Effect of tabula rasa, it is impossible to meet the demand of people.
Utility model content
The purpose of this utility model is to solve shortcoming and defect present in above-mentioned prior art, there is provided a kind of transparent
PMMA light guide plates；Specifically light guide plate main body is provided with the shiny surface as incidence surface and the male and fomale(M＆F) as exiting surface, and this is concavo-convex
Face is spliced by several cones；When light is injected from incidence surface, the cone of exiting surface initially plays optically focused effect,
Prevent light from being reflected in the light inlet of exiting surface, improve the effective rate of utilization of light；After light enters into exiting surface, light exists
Continuously reflected in the exiting surface be made up of cone, final convergence forms a hollow even aperture and interior be connected to the even light light
Enclose and the even optic angle star darker than the even aperture is projected, so as to solve the problems, such as that direct-injection type light source can produce dazzle, the even light
Angle star may also function as the effect decorated, beautify.
The utility model solve technical scheme that its technical problem used for：A kind of transparent PMMA light guide plates, including lead
Tabula rasa main body, the light guide plate main body is provided with incidence surface and exiting surface, and the incidence surface is shiny surface, and exiting surface is and shiny surface
Opposite male and fomale(M＆F), male and fomale(M＆F) is spliced by several cones, and the both sides of light guide plate main body are additionally provided with assembling card article, assembling
The thickness of card article is the 1/2 of the thickness of light guide plate main body, and the thickness of light guide plate main body is 3 ~ 4mm, assembling card article and incidence surface shape
Step is formed into smooth splicing and with exiting surface.When light is injected from incidence surface, the cone of exiting surface initially plays optically focused
Effect, prevents light from being reflected in the light inlet of exiting surface, improves the effective rate of utilization of light；After light enters into exiting surface,
Light is continuously reflected in the exiting surface being made up of cone, and final convergence forms a hollow even aperture and interior be connected to this
Even aperture and the even optic angle star injection darker than the even aperture, so as to solve the glare problem of direct-injection type light source generation, should
Even optic angle star may also function as the effect decorated, beautify.Assembling card article solves the problems, such as that existing light guide plate is difficult and installs, can use
Engaging is installed, and will not be touched with the exiting surface of light guide plate main body and incidence surface without fixture, and installation site, it is to avoid
Exiting surface and incidence surface are impaired.
Further, the light guide plate main body is structure as a whole with assembling card article.
Further, the cone is positive hexagonal pyramid, and the height of positive hexagonal pyramid is the 1/3 of light guide plate main body thickness.This
When, the even optic angle star for being inside connected to even aperture is the positive Magen David of even light.
Further, the thickness of the light guide plate main body is 3.5mm.
In sum, the transformation that the utility model passes through structure, light guide plate main body be provided with as incidence surface shiny surface and
Used as the male and fomale(M＆F) of exiting surface, the male and fomale(M＆F) is spliced by several positive hexagonal pyramids；When light is injected from incidence surface, light extraction
The positive hexagonal pyramid in face initially plays optically focused effect, prevents light from being reflected in the light inlet of exiting surface, improves effective utilization of light
Rate；After light enters into exiting surface, light is continuously reflected in the exiting surface being made up of positive hexagonal pyramid, and final convergence forms one
Individual hollow even aperture and it is interior be connected to the even aperture and the positive Magen David of the even light darker than the even aperture is projected, so as to solve
Direct-injection type light source can produce the problem of dazzle, be felt comfortably cool when watching naked eyes, the even positive Magen David of light may also function as decoration,
The effect of beautification.Meanwhile, the assembling card article located at light guide plate main body both sides solves the problems, such as that existing light guide plate is difficult and installs, can
Installed using engaging, will not be touched with the exiting surface of light guide plate main body and incidence surface without fixture, and installation site,
Avoid exiting surface and incidence surface is impaired.
