如何在lighttools内给导光板加上网点?

今天我是第二天使用LOGHTTOOLS,很多功能不会使,我希望作一个导光板,但是加不上网点,为什么呢?请各位指教指教。谢谢!

不可能加不上网点的。

如何加上网点?
wab6 2006-08-29 09:39
能不能将其它网点格式文件中导入???
hyado2000 2006-08-29 11:44
我也想知道,可以用autocad的網點嗎
蔡永利 2006-08-31 15:05
我已经可以在lt中加上网点了,只是不只如何将网点导成印刷稿。还请各位大哥大姐帮忙看看。

此问题已解决OK,用AUTOLIST作转换就可以了,如果谁有兴趣,可以把方法公开.

很简单的,LT自带一个插件,在tools下打开插件,在介绍指南中有详细描述
蔡永利 2006-09-30 10:33
这个插件好像不能解决复杂形状的导光板问题
gyqlxm 2006-10-01 14:42
是指LG的外形复杂呢?还是指网点排列规律复杂?
suezl9 2006-10-09 09:20
网点的规律复杂的怎么设置啊请问????
gyqlxm 2006-11-19 20:24
可以texture里面设置,BEZIER曲线和二项式等方式
zww480542 2006-11-30 19:40
用LT怎样表示蚀刻的网点,
zww480542 2006-11-30 19:43
有没有蚀刻网点的案件呀,多谢
lulalawind 2007-03-15 12:24
它的utilities裡不是有一個建Backlight的模組,裡面就有加網點的功能呀

谢谢楼主!正需要.

geguocheng 2007-04-11 14:51
我也刚开始用, l0|5t)jF-  
不知道导光体为什么不能导出光来,只有接收端有亮度,其他输出端都测不到亮度呢?
daoguang 2007-05-06 12:14
这个软件那里有下载的,请帮帮小弟,谢谢。
trojan-1 2007-07-01 10:45
小弟是新手,请问相对于ASAP,在设计导光板方面,LT有什么优和缺,能比较下吗???谢了
ycl641 2007-07-07 10:22
请问auto-cad的网点怎么导入啊,还有那个autolist是一个什么样的插件哦?

把网点参数写成.TXT格式,在导光板的TEXTURE中导入就可以在LT 中得到网点,只是中间要有个坐标转换,计算要精解. xVw9v6@`h  
多试几次就可以了.

lighttools有一個插件叫DXF Tool,可以把autocad的圖檔先轉成DXF檔,然後再吃進去lighttools,也可以把lighttools的網點轉出成dxf檔,讓autocad讀。

Parameterize the Bumps r-,%2y?  
The Backlight Utility was helpful to build the backlight system quickly. However, wH*-(*N "  
the bumps must be parameterized in order to get the desired output distribution. %O;:af"Ja8  
You can do this easily using the LightTools Properties dialog box. &0d# Y]D4`  
1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, 7P } W *  
BottomSurface, and Zones. Then, select Texture, as shown in the following 'B |JAi?  
figure. ]U+ LJOb  
2.Right-click and select Properties on the shortcut menu. xR~h wj  
3.Select the Geometry tab. .e#w)K  
4.Select the arrow next to the Placement drop-down list, and select Bezier. Click "69s) ~

The default number of bumps is 100 (10 X 10). You need to change these RbB.q p  
parameters to match your design. Note that LightTools allows many other p%ki>p )E|  
placement options, but you will use the Bezier placement option for this PI {bmZ  
example. Xg6Jh``  
5.On both the X Placement tab and Y Placement tab, change the Number of 1er TldX  
Bumps parameter to 300, as shown in the following figure. Click Apply after 1C+13LE$U  
each change. {p2!|A&a  
6.Click OK to close the dialog box. cVv=*81\  
Note that the number of bumps is 300 X 300, which results in about 90,000 AI2)g1m  
bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a MpT8" /.]A  
manner defined by the Bezier parameterization option. Please see Chapter 5 of rI{; IDV  
the LightTools Core Module User’s Guide for more information. With the hPkp;a #  
current parameter values, the Bezier option varies the bump spacing along the 8S TvCH"Z_  
length of the light guide. The spacing in the orthogonal direction is constant. ScOK)nL"  
The X and Y refer to the local coordinate system of the surface. E:68?IJ

You might be curious as to why you cannot see the 3D texture property zones you n&4N[Qlv,

1 是autolisp 不是autolist +)om^e@.  
2 在autocad中是用autolisp编写插件,实现将网点参数之坐标和半径读取并另存为 76Cl\rV  
txt档的命令,只要有坐标和半径就ok了,excel档也无所谓。看你喜欢 7F7 {)L  
3 在lighttoools使用texture命令,建立一个圆点的矩阵,在坐标一栏中,把原有的删除 :pY/-Cgv  
贴上你在cad中读出的数据就好了。半径的参数一样办理 iuW[`ou X  
4 关键是cad中网点的坐标位置要和lighttools模型的位置对应的上,否则,你贴上去网点位置在离模型很远的地方就不厚道了

我想学学,大哥大姐帮个忙.
yukoko 2008-05-08 15:44
呵呵,这个问题我用了个方法解决了. 33x{CY15  
我要模拟的是在导光板背后的印刷网点,要用一些变化的网点才可以达到600X600这么大的面积用LED为光源的区域照度均匀. BO ;tCEV?  
我的网点是圆开的,然后我用的方法是,在LT里网点用TEXTURE,类型选CONE,将高度设成很小(0.01),这样就形成了一个很薄的圆斑,然后将它的光学特性选为散射(SCATER,REFLECT),这样子就可以运用LT里的参数化的排列来做印刷网点的设计了. nwe* BVp  
我这样做出来与实际测试差不多.贴出来与大家共分享.
