无极灯发光体的排气充气在线检测装置及检测方法 技术领域
本发明涉及无极灯发光体的排气充气在线检测装置及检测方法。 背景技术
无极灯应用电磁感应原理将电磁能量传递给发光体内的汞离子,所述发光体也即灯 泡或灯管, 并产生紫外线, 灯泡或灯管内表面涂荧光粉层, 它吸收紫外线辐射, 发出可 见光。 其过程为高频发生器通过高频电馈线给高频线圈供电, 产生高频电磁场, 汞离子 被高频电磁场激发后产生紫外、 可见光谱线辐射,它的紫外、 可见光谱线包括紫外
185nm、 253.7nm、 365nm, 以及可见光權 .6nm、 435.8nm 546.1nm 577nm 579nm波长等等, 其中 253.7nm和 365nm紫外线激发玻壳内表面的荧光粉涂层, 紫 外线被荧光粉吸收后发出可见光。 灯泡内的汞蒸气压由汞齐提供。
基于这一原理, 灯泡或灯管不需要灯丝, 因此, 无极灯的使用寿命很长, 可达 6-10 万小时, 发光效率达 80流明 /瓦, 是一种高光效、 长寿命的新颖节能光源。
无极灯分内置式和外置式, 内置式无极灯的发光体往往为灯泡, 所述灯泡具有设置 高频线圈的凹腔, 外置式无极灯的发光体多为灯管, 所述高频线圈绕在灯管外。
要制造高质量的无极灯灯泡、 灯管, 需要用二个主要的技术指标来衡量:
A、 高的发光效率, 流明 /瓦 (lm/W),
B、 稳定的光束色温。
根据低气压汞蒸气放电原理,当汞蒸气压为 0.8 Pa时 253.7nm紫外辐射效率最大, 可获得光源的最高发光效率和稳定的光束色温。 汞蒸气压偏离 0.8 Pa时, 253.7nm辐 射效率降低, 其他辐射谱线增加, 光束色温改变。 由于无极灯的工作温度较高, 并考虑 环保的要求, 一般应用汞齐建立汞蒸气压, 为获得 0.8 Pa汞蒸气压条件, 需确定最合 适的高温汞齐型号, 达到高光效和稳定的光束色温。
此外, 发光体内还要充入一些惰性气体, 称为缓冲气体, 如氩气、 氪气。 它可以增 加汞离子间的碰撞机会, 减少在发光体内壁上的碰撞损失, 提高辐射效率。 但惰性气体 也不能充入太多, 否则也会造成与离子间碰撞引起的能量损失。 对于不同功率和体积的 发光体需要充入最佳的惰性气体气压值, 才能获得最高的发光效率。
目前, 无极灯生产线上的工作程序如下:
A、把己涂荧光粉的无极灯泡、置于高温加热罩下排气抽真空,然后移去加热罩; 充 入惰性气体, 以火花检漏器估计充入惰性气体的气压是否合适;
B、 参照图 1, 图 1是充入惰性气体、 割下灯泡的 4个工序: 工序 1、 从抽真空工 位的充、 排气台上割下灯泡; 工序 2和 3、 将灯泡移至注汞齐工位, 倒转 180度, 注入 汞齐 m至合适位置; 4, 将灯泡上的玻璃导管割下并封口。
C、 把制作完成的无极灯泡、 与高频发生器和高频线圈组成一只可点亮的无极灯。 综上所述, 目前无极灯生产线上, 灯泡 (灯管)的惰性气体气压大小, 仅仅是用火花 检漏器来估计, 要点亮灯泡 (灯管)又必须要其在充、 排气台上割下才能实现, 每种功率 的无极灯所需惰性气体最佳气压是不同的, 需要多次试验才能确定, 采用传统的工序和 设备, 要反复经过数十次的充气、 割下操作, 才能确定最佳惰性气体充气气压, 因此不 可能很快获得最佳光色技术参数的高品质无极灯泡 (灯管), 并且, 由于试验操作的麻烦, 其获得的光色技术参数往往不是最佳的参数。 发明内容

(3)、将预设定温度的汞齐 9放在汞齐置入导管 8外端, 置于加热罩外, 防止被加 热, 升上加热罩 19, 使加热罩 19移开, 利用在汞齐置入导管 8外运动的磁铁 11, 比 如用机械装置或手动来移动磁铁 11, 吸引所述柱体 10, 使柱体 10带所述汞齐 9移动 至发光体的汞齐设置处, 即汞齐置入导管 8的折弯处 81;
(4)、 充入几 Pa惰性气体, 起动高频发生器, 给高频线圈馈电, 发光体被点亮;
(5)、利用对准灯泡形发光体中心部位的彩色亮度计测量灯泡形发光体中心部位亮 度值、 相关色温和色品座标值, 将数据通过 RS232或者 USB接口送至所述计算机处理、 记录;
(6)、 再以 l-5Pa 步长手动充入惰性气体, 如汞齐 9离开发光体的汞齐设置处, 利用在汞齐置入导管 8外运动的磁铁 11吸引所述柱体 10运动, 带汞齐 9移动至发光 体的汞齐设置处, 通过彩色亮度计对准灯泡形发光体中心部位, 将灯泡发光体中心部位 亮度值、 相关色温和色品座标值送至所述计算机;
(7)、 重复步骤(6), 逐步增加发光体内的气压, 直至测得的亮度值、 相关色温和 色品座标值达到最佳值, 并记录此时的真空表数据。
进一步地, 在获得上述最佳值对应的发光体内的气压值后, 进一步检查色温变化曲 线, 如色温变高, 则需采用更高温的汞齐, 调整更高温度规格的汞齐, 利用所述彩色亮 度计测量发光体亮度值、 相关色温和色品座标值, 用所述计算机比较前后不同温度的汞 齐所对应的亮度值、 色温 和色品座标值, 待亮度值、 相关色温和色品座标值稳定时, 获得汞齐的最佳温度值。应用这一汞齐参数和上述气压值能使无极灯达到最高的发光效 率 (lm/W)和稳定的光束色温。 从充排气导管 40上割下灯泡, 高质量无极灯试验完成。 进一步批量生产时, 应用这一参数的汞齐和发光体内气压可获批量优质无极灯。 实施例 2, 参照附图 3、 4。
本实施例为为自动在线无极灯发光体充气在线检测装置的实施方式。
在本实施例中, 实施例 1中的供气阀 2采用电磁阀, 它由所述计算机 18控制, 代 替手动充惰性气体,真空表 3接入计算机采样,并以发光体内气压 l-5Pa的步长为标准, 自动充入惰性气体, 完成全部数据处理, 记录和分析工作。
本实施例中, 在实施例 1的检测方法的基础上, 在所述步骤 (2) 中, 由所述计算 机 18根据真空表 3输出的数据判断是否达到设定的真空度, 如达到, 在步骤(4) 中充 入惰性气体;
所述在线监测方法通过所述计算机控制惰性气体供气装置的供气电磁阀打开和关 闭来控制惰性气体的充入量。 实施例 3, 参照图 5。
图 5演示了为外置式无极灯发光体的汞齐结构, 其发光体呈管型, 在图 5中, 附图 标号与图 2-4相同的为相同的技术特征, 对于该管型发光体的充气检测装置, 和实施例 1、 2相同。 实施例 6, 参照图 6。
应用实施例 1或 2所述的充气检测装置, 通过 XYLVI彩色亮度计 15瞄准 2700K 色温 蘭无极灯灯管中心部位, 将灯管中心部位亮度值、 相关色温和色品座标值经 RS232或者 IEB接口 16送至计算机 18处理、 记录的光束参数。
XYLVI彩色亮度计软件显示的红、 绿线为 xy色品座标, 蓝线为亮度值, 淡蓝线为 相关色温。
该曲线图可以分析, 由于所选用的汞齐温度太低, 导致亮度下降, 色温上升, 因此 需更换更高温度汞齐。 实施例 7, 参照图 7。
应用实施例 1或 2所述的充气检测装置, 通过 XYLVI彩色亮度计 15瞄准 2900K 色温 蘭无极灯灯管中心部位, 将灯管中心部位亮度值、 相关色温和色品座标值经 RS232或者 IEB接口 16送至计算机 18处理、 记录的光束参数。
该曲线图可以分析, 汞齐温度合适, 色温稳定, 亮度高, 参数正确。
