Description

紫外线荧光灯组件以及配向紫外线照射装置 技术领域
本发明涉及荧光灯技术领域,尤其涉及一种紫外线荧光灯组件。本发明还涉及在液晶显示器制造领域中，在液晶配向工艺中使用的配向紫外线照射装置，该装置包含前述的紫外线荧光灯组件。
背景技术
液晶显示装置(LCD，Liquid Crystal Display)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括液晶显示面板及背光模组(backlight module)。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，通过玻璃基板通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。
液晶分子的配向控制技术是制造液晶显示器(liquid crystal display)最重要的基本技术之一。液晶显示器所显示的画面质量与液晶配向的优劣有关，只有使面板内的液晶材料呈稳定且均匀的排列，才能呈现高质量的画面。一般用来使液晶分子定向排列的薄层，称为液晶配向层(alignment layers)。
所谓HVA(高电压激活，high-voltage-activated)光配向技术是指在给基板100施加电压的情况下，通过UV光(紫外线光，Ultraviolet Rays)照射促使面板内高分子的单体(monomer)反应，从而达到液晶配向的目的。目前，HVA光配向技术已广泛应用于高世代TFT-LCD行业中，为保证液晶在UV光照射下能形成特定的配向角而不产生Mura(指显示器亮度不均匀，造成各种痕迹的现象)，UV光的照射均匀度是关键，HVA光配向技术中UV光照度需在85±10％毫瓦/平方厘米以内。在液晶配向工艺中需要的UV光通常由配向紫外线照射装置提供，配向紫外线照射装置中设置有若干紫外线灯管(UV Lamp)。
UV Lamp为低压荧光灯，需要安定器(又称镇流器)进行启动和稳压。如图1所示的一种现有的紫外线荧光灯组件的电路连接示意图，安定器将接收的市电交流电AC，提供工作电压和工作电流给荧光灯管，安定器的作用为：提供 足够灯管启动的电压与稳定灯管工作电流。目前工业用低压荧光灯UV Lamp通常采用电子安定器，其优点在于电子安定器为高频(20kHz～60kHz)瞬时点灯，荧光灯产生的光线非常稳定几乎无闪烁。图2为现有的一种电子安定器的结构框图，电子安定器包括滤波器、整流器、缓冲电容器、高频振荡器以及稳定装置，安定器将接收的市电交流电AC经过滤波、整流以及高频振荡后提供给荧光灯管。
UV Lamp的发光原理为灯管内水银或者惰性气体经灯管两端灯丝加热蒸发，形成稀薄的汞(惰性气体)蒸汽，安定器产生的高压加在灯管两端，使汞原子(惰性气体)电离出电子，电子加速后与汞(惰性气体)原子碰撞，使气体迅速击穿，产生弧光放电，激发紫外线，紫外线再激发涂在管壁上的荧光粉，发出柔和的光。UV Lamp点灯时间增长，开关次数增多后，灯管内的汞蒸汽及荧光体会减少，灯管照度会衰减。图3示出了现有的通常使用的两种UV Lamp的照度维持率曲线L1和L2。如图3所示的，该两种UV Lamp寿命约为8000小时，其照度在刚安装即点灯时间0小时时照度最强，在前100小时照度衰减最快，衰减约5％～10％，点灯时间到达1000小时后照度衰减约10％～15％，点灯时间达到8000小时时照度衰减约30％～40％。
目前使用的电子安定器，如图2所示的结构框图，其无法调节输出电压及频率，因此无法调节UV Lamp的照度，导致新安装的UV Lamp与使用过一段时间的UV Lamp的照度差异较大，若到使用时数到8000小时后照度差异高达30％～40％。通常情况下工厂生产为了保证稳定性，配向紫外线照射装置的照射时间设定为一个定值，这样导致刚安装的UV Lamp照射的积算光量(积算光量＝照度*照射时间，当照射时间一定时，积算光量与照度成正比)比有一定使用时数的UV Lamp的积算光量高，这会造成生产稳定性差，对产品品质造成影响。
