Description

陶瓷放电管金属卤化物灯 技术领域
本发明涉及一种金属卤化灯, 特别涉及一种水平燃点的高光效陶瓷放电管金属卤化物灯。 背景技术
陶瓷放电管金卤灯已经越来越被广泛使用, 一般的陶瓷放电管金卤灯在陶瓷放电管内形 成放电腔, 放电腔内充有惰性气体 (如氙气 Xe) 和可电离盐, 放电腔内放置一对电极分别位 于陶瓷放电管的两端, 两个电极尖端具有一定间距以便在其间形成放电路径。 目前的一般陶 瓷金卤灯陶瓷放电管不论是一体式, 还是二体式、 三体式, 甚至更早的五体式的, 陶瓷管体 外观的几何形状都有一个共同的特点: 陶瓷放电管均由三部分组成, 即中间放电部分的粗圆 柱体 (如图 1所示) 或椭球体 (如图 2所示) 以及两边的两个同轴细圆柱体。
为提高陶瓷放电管金卤灯的发光效率, 目前多采用的高光效的陶瓷放电管金卤灯的设计 结构如图 3所示, 其陶瓷放电管通常采用细长型陶瓷管体, 这种细长型陶瓷管体的特点是中 心的最大内径 D1小于电极之间的距离 L1。采用这种机构的陶瓷放电管虽然可以达到高光效的 目的, 但也存在一定的缺点。 首先是这种细长型陶瓷管体内径小, 管壁负载大, 水平燃点时, 电弧弯曲(arc bending)会使管壁上端中央部分温度过高, 从而引起陶瓷管体的管壁的变性, 甚至断裂, 会严重影响产品的可靠性和安全性。
除了管壁上端中央温度过高, 会引起陶瓷管体的管壁变性、 断裂这个缺点外, 这种细长 型设计的陶瓷放电管的另一个比较突出的问题是: 由于管体细长, 水平燃点时冷端温度在距 离电弧中央较远的两端, 而且位置不定, 这样陶瓷放电管内的填充物就没有固定的冷凝点, 从而造成色温的不稳定, 使得灯与灯之间色温的差异大、 单个灯的色温随时间的漂移明显, 严重影响了灯的照明品质。
再有, 目前通常使用的金属卤化物灯内的填充物一般是含有 DyI3、 HoI3、 TmI3等稀土金 属的金属卤化物系列, 这些金属卤化物虽然可以使灯具有优越的显色性, 但是由于这些金属 卤化物在高温下具有很强的腐蚀性, 因此并不适合在高光效陶瓷金卤灯中使用。 发明内容
针对上述现有技术的不足, 本发明要解决的技术问题是提供一种在保证高光效的前提下, 有效应对电弧弯曲对电弧管壁的影响, 降低水平燃点时管壁中间上端的最高温度, 减小整个 陶瓷管体的温差的陶瓷放电管金属卤化物灯。
为解决上述技术问题, 本发明采用如下技术方案:
一种陶瓷放电管金属卤化物灯, 包括一个陶瓷放电管和两个电极, 所述陶瓷放电管内形 成放电腔, 所述放电腔内设有填充物, 所述陶瓷放电管包括一个放电主管和分别位于所述放 电主管两端的两个陶瓷毛细管, 所述两个电极分别插在两个陶瓷毛细管内并伸入所述放电腔 内, 两个电极彼此相对, 所述两个陶瓷毛细管的外端部密封, 所述放电主管具有一位于其中 间的中央鼓起部和分别与所述中央鼓起部两端连接的两个柱状部, 所述两个柱状部分别与所 述两个陶瓷毛细管连接, 所述中央鼓起部的内径大于所述柱状部的内径, 所述两个电极之间 的距离大于所述中央鼓起部的最大内径。
优选的, 所述中央鼓起部两个外端面之间的距离 A、 放电主管两个外端面之间的距离 B、 陶瓷毛细管的内径 C、 柱状部的内径 D、 中央鼓起部的最大内径5、 两个电极之间的距离 L满 足以下关系: 0. 2〈A: B〈l, 0. 3〈D : E〈1, 0. 2〈E : L〈1。
优选的, 0. 3<A: B〈l, 0. 4<D : E<0. 6, 0. 3〈E : L〈0. 6。
优选的, 所述中央鼓起部的形状为球状、 椭球状或部分椭球状。
优选的, 所述填充物包括 Nal和卤化物 X, 所述卤化物 X为 LaI3、 CeI 3和 PrI 3中的一种 或多种, 其中 Nal/X的摩尔比处于 4和 18之间。
进一步的, Nal/X的摩尔比处在 5和 16之间。
进一步的, Nal/X的摩尔比处在 6和 14之间。
优选的, 所述卤化物 X为 PrI 3与 LaI 3的混合物, 其中 PrI3/LaI3的摩尔比处于 0. 2和 2 之间。
优选的, 所述卤化物 X为 PrI3、 LaI 3和 CeI 3的混合物。
优选的, 所述填充物中还包括 T1 I或 CaI2。
上述技术方案具有如下有益效果: 由于该金属卤化物灯在陶瓷放电管的中间设置有中央 鼓起部, 陶瓷放电管形成的放电腔中间向外鼓起, 使得陶瓷放电管中间的管壁离两个电极放 电产生的电弧较远, 这样即使在电弧弯曲上拱的情况下, 陶瓷放电管中间的管壁温度也不会 太高, 可以有效防止陶瓷放电管的断裂, 同时采用这种结构也会在中央鼓起部形成的放电腔 的下端形成固定的冷点, 使填充物可以一直较为固定地沉积在该冷点处, 这样可有效增加该 陶瓷放电管金属卤化物灯色温的稳定性。 再有该陶瓷放电管金属卤化物灯的填充物在高温下 不会产生强腐蚀性, 可提供高于 110LPW的高光效的白光, 同时具有良好的显色性和稳定的色 温。 附图说明

具体实施方式
下面结合附图对本发明的优选实施案例进行详细介绍。
如图 4所示, 该金属卤化物灯包括一石英管 2, 石英管 2内设置陶瓷放电管 1, 陶瓷放电 管内形成放电腔, 放电腔内设有填充物。 陶瓷放电管 1的两端各设置一电极 3, 两个电极 3分 别从两端***陶瓷放电管 1形成的放电腔内, 两个电极 3相对, 两个电极 3的外端分别与石 英管 2上的两个外电极 4连接。 两个外电极 4与电源连接使两个电极 3通电, 两个电极 3之 间放电产生电弧来发光。
如图 5所示, 陶瓷放电管 1包括一个放电主管和分别位于放电主管两端的两个陶瓷毛细 管 11, 两个电极 3分别穿过两个陶瓷毛细管 11并伸入到放电腔 14内, 两个电极 3彼此相对, 两个陶瓷毛细管的外端部通过封接焊料 5进行密封。 放电主管包括一个位于中间位置的中央 鼓起部 13以及分别与该中央鼓起部 13两端连接的两个柱状部 12,两个柱状部 12分别与两个 陶瓷毛细管 11连接。 中央鼓起部 13的形状可以采用球状、 椭球状或部分椭球状, 中央鼓起 部 13的内径大于柱状部 12的内径, 两个电极 3之间的距离大于中央鼓起部 13的最大内径。
如图 6所示, 记中央鼓起部两个外端面之间的距离为 A、放电主管两个外端面之间的距离 为 8、 陶瓷毛细管的内径为 C、 柱状部的内径为 0、 中央鼓起部的最大内径为 E、 两个电极之 间的距离为 L, 则上述参数应满足以下关系式: 0. 2〈A: B〈l, 0. 3〈D : E〈1, 0. 2〈E : L〈1。优选的, 0. 3<A: B〈l, 0. 4<D : E<0. 6, 0. 3〈E : L〈0. 6。
由于该金属卤化物灯在陶瓷放电管的中间设置有中央鼓起部, 陶瓷放电管形成的放电腔 中间向外鼓起, 使得陶瓷放电管中间的管壁离两个电极放电产生的电弧较远, 这样即使在电 弧弯曲上拱的情况下, 陶瓷放电管中间的管壁温度也不会太高, 可以有效防止陶瓷放电管的 断裂。 下表为本发明两个实施案例与目前常规高效金属卤化物灯的对比: 功率 A: B D : E E : L 水平燃点管壁上端中央最高温 案例 1 140W 0. 48 0. 53 0. 4 1180°C
案例 2 140W 0. 9 0. 53 0. 4 1160°C
对比常规设计 140W 1 1 0. 2 1320°C 从上表可知, 采用该结构的金属卤化物灯可以达到有效降低陶瓷放电管中间管壁温度的 目的, 由此可见本发明所述陶瓷放电管的形状可在保持高光效的前提下, 有效降低管体中央 的最高温, 大大增强灯的可靠性。 同时采用这种结构也会在中央鼓起部形成的放电腔的下端 形成固定的冷点, 使填充物可以一直较为固定地沉积在该冷点处, 这样可有效增加该陶瓷放 电管金属卤化物灯色温的稳定性。
本发明还公开了一种该金属卤化物灯的填充物,该填充物包括 Nal和由 LaI3、CeI3和 PrI3 中的一种或多种组成的卤化物 X, 其中 Nal/X的摩尔比处于 4和 18之间, 优选的, Nal/X的 摩尔比位于 5和 16之间,再进一步优选, Nal/X的摩尔比可位于 6和 14之间。作为一种优选, 卤化物 X可采用 PrI3与 LaI3的混合物, 其中 PrI3/LaI3的摩尔比处于 0. 2和 2之间, 卤化 物 X也可采用 PrI3、 Lai 3和 CeI3的混合物。
上述填充物在高温下不会产生强腐蚀性, 适合在高光效陶瓷金卤灯中使用, 并可提供高 于 110LPW的高光效的白光,其显色指数 CRI高于 70,具有良好的显色性和稳定的色温。再有, 为了进一步提高该金属卤化物灯的光效, 可以在填充物中添加 T1I, 为了进一步改善该金属卤 化物灯的显色, 可以在填充物中添加 CaI2。 该金属卤化物灯的缓冲气体最好选用氙气, 以提 高光效, 提高光通量维持率。
以上对本发明实施案例所提供的陶瓷放电管金属卤化物灯进行了详细介绍, 对于本领域 的一般技术人员, 依据本发明实施案例的思想, 在具体实施方式及应用范围上均会有改变之 处, 综上所述, 本说明书内容不应理解为对本发明的限制, 凡依本发明设计思想所做的任何 改变都在本发明的保护范围之内。
