Description
Technical field
The invention belongs to light guide plate technical fields, and in particular to a kind of light guide plate mesh point that outgoing light homogeneity is high arrangement knot
Structure.
Background technology
Light guide plate is the critical optical device of flat lamp, its effect is the light that the light source that side is shone is sent out, and is passed through
The importing of light guide plate, from light guide plate side into light direction, by the repeatedly light variation such as incidence, refraction, reflection, diffusing reflection,
Become, relative to the straight to shining of flat lamp plane, from the front outgoing of light guide plate, to generate illumination functions, to illuminate ring around
Border.In order to realize light-guiding function, in the one side of light guide plate, by the method for silk-screen printing, in light guide plate surface, print very much
Dot, these dots are exactly the site of light guide plate.Therefore the net-pont design scheme on light guide plate, is related to entire lamps and lanterns and goes out
The using effect of light.Traditional net-pont design scheme has the disadvantage that：
1. diameter is identical, as light is after the transmission scattering of light guide plate, luminous flux luminous intensity constantly decays, therefore
Outgoing light homogeneity is poor；
2. light extraction efficiency is not high.
Invention content
The purpose of the present invention is overcoming defect of the existing technology, one kind is provided from each light source inlet to light guide plate
Symmetrical center line on, the diameter of the sites 1-155 is incremented by successively, and scattering surface also gradually increases, and light extraction efficiency is high and light extraction is equal
The high light guide plate mesh point arrangement of evenness.
The technical solution adopted by the present invention to solve the technical problems is：A kind of light guide plate mesh point cloth that outgoing light homogeneity is high
Set structure comprising the opposite two edges of light guide plate, light guide plate are light source entrance, and the scattering plate face of light guide plate is equipped with site
Matrix；From each light source inlet to the symmetrical center line of light guide plate, it has been sequentially arranged in the file of each site matrix
The diameter of the sites 1-155, the sites 1-155 is shown in Table 1：
The diameter table of 1. sites 1-155 of table
The center spacing of two sites of the arbitrary neighborhood in the matrix of site is 1.8-1.85mm.
The opposite one side for scattering plate face is transparent light outgoing plane.Opposite two of the site of the present invention from light guide plate
After edge (i.e. light source entrance) enters, light constantly scatters on site, in the symmetrical center line of directive light guide plate
Direction on luminous flux gradually decay.The present invention tests each site to obtain optimal value by distribution photometer, i.e., from each light
To in the symmetrical center line of light guide plate at source inlet, the diameter of the sites 1-155 is incremented by successively, and scattering surface also gradually increases, and goes out
The light uniformity is high, and light extraction efficiency is high.The both sides luminous light guide plate formed according to this programme has the best uniformity and most
Good light emission rate.
Preferably, the center spacing of two sites of the arbitrary neighborhood in the matrix of site is 1.8236mm, most convenient for arrangement
The site of the figure of merit.
Further, the site in the matrix of site is the ink dot of silk-screen printing, in acrylic organic glass
On light guide plate after silk-screen printing, scattering efficiency is high, and light service efficiency is high, easy to make.
A kind of advantageous effect of the high light guide plate mesh point arrangement of outgoing light homogeneity of the present invention is：
1. the present invention tests to obtain optimal value by distribution photometer in each site, i.e., from each light source inlet to light guide plate
Symmetrical center line on, the diameter of the sites 1-155 is incremented by successively, and scattering surface also gradually increases, and outgoing light homogeneity is high, and light extraction
It is efficient.
2. the both sides luminous light guide plate formed according to this programme has the best uniformity and best light emission rate.
