Constantly scattered on site on propagation path, so as to which the light on the direction of the symmetrical center line of directive light guide plate leads to
Amount gradually decay.According to the rule, by the experimental test of distribution photometer, the utility model, which draws to finish, closes growth function
Net-pont design scheme, there is light source side to the center line online spot diameter of light conducting plate body regularly gradually to increase from each.From
And after light conducting plate body both sides of the present utility model are luminous, after being scattered the site scattering on face, the plane relative from scattering surface
The uniform light of middle injection, there is maximum light emission rate.
, can be according to the size of light conducting plate body, within the shorter time, with certain value by the utility model
Two neighboring site spacing, optimal site arrangement is drawn, be not required to test for a long time, improve development ＆ production effect
Rate.
Specifically, growth function is Y=K/ (1+e^ (a+bx)), wherein, K=2.8862, a=0.558, b=-
0.00533, there is light source side from each total dot is 155 to the center line of light conducting plate body, then the net of both sides starting point
Spot diameter is：1.054mm, light guide plate centre maximum web spot diameter：1.64mm, the light emission rate now measured by distribution photometer
It is highest.
Preferably, the center spacing of two sites of arbitrary neighborhood in light conducting plate body is 1.8~1.9mm, can arrange
Different-diameter site, arrangement are convenient.
Preferably, light conducting plate body is acrylic poly (methyl methacrylate) plate, PS plastic plate or MS plastic plates, be easy to silk-screen printing or
Laser engraving site.
A kind of beneficial effect of the big flat lamp light guide plate mesh point arrangement of light emission rate of the present utility model is：
1. the utility model after light conducting plate body both sides are luminous, is scattered face by the net-pont design scheme of growth function
On site scattering after, the uniform light that is projected in the plane relative from scattering surface, there is maximum light emission rate；
2. can be according to the size of light conducting plate body, within the shorter time, with the two neighboring net of certain value
Point spacing, draws optimal site arrangement, is not required to test for a long time, improve development ＆ production efficiency.
