Description

高效低眩光车用高强度放电灯
技术领域
本实用新型涉及一种带灯头的车用高强度放电灯。
背景技术
现有带灯头的高强度放电灯通常结构为： 包含一个用高纯石英玻璃制 成的气密型并充有可电离物质的呈类似球状或椭球状的气体放电电弧管， 电弧管两端设有互成 180度角的直径收縮且密封的颈体部分。 为了保证电 弧管工作的稳定性， 电弧管及颈体外还设有罩壳， 罩壳用吸收紫外光的石 英材料制成， 可以是气密型的， 也可是非气密型的。 与电弧管一对电极连 接的导体分别穿过对应端颈体伸出电弧管及罩壳外， 近灯头端引线与设在 该端灯头上的电源连接端电连接， 另一端引线则从罩壳外侧折向灯头并与 灯头上的另一电源连接端电连接。 现有的车用高强度放电灯的罩壳均为直 筒形， 而电弧管则呈类似球状或椭球状、 并且与管状罩壳间的距离很小， 使得电弧管与罩壳之间距离很不均匀， 这样一方面会造成电弧管温度的不 均匀， 影响热稳定性， 而更严重的是会造成电弧管辐射的光到达管状罩壳 内壁时因入射角较大， 一部分光会穿出罩壳而另一部分光则会在直管形罩 壳内壁与电弧管外壁之间多次反射后散向四周及两端'（参见图 3)， 这不仅 · 降低了光利用率， 还会使光分布曲线和灯具的聚光效果变劣， 产生^ ^大的 眩光。 现有结构的产品大都将电弧管罩壳较深地***灯头并以胶固定， 其 不足之处是不够牢固又易造成泡壳下部破碎， 有的则是在灯头上设置一个 金属固定部件， 金属固定部件与紧箍罩壳的金属环焊接连接， 这种连接方 式的结构比较复杂， 安装繁琐， 价格较高。
发明内容 本实用新型的目的是提供一种结构简单牢固、 安装方便、 光利用率高、 热稳定性能较好、 低眩光的带灯头车用高强度放电灯， 且能进一步提高其 抗震性能。
为达上述目的， 本实用新型采用以下的技术方案：
一种高效低眩光车用高强度放电灯， 包含有： 设有类似球状或椭球状 气密型并充有可电离物质的电弧管， 电弧管二端设有互成 180度角的两段 直径收缩且密封的第一颈体和第二颈体。 电弧管内的第一电极、 第二电极 分别通过相应端颈体内的导电体与管外的第一电极引线和第二电极引线电 连接， 第一电极引线与设在同一端的灯头上的第一电源连接端电连接， 第 二电极引线折回灯头方向并与灯头方向上的第二电源连接端电连接， 电弧 管和颈体外设有包围其的罩壳， 罩壳上与电弧管相对应的部位同样是向外 鼓出且与电弧管类似的球状泡壳或椭球状、 两者的壁面为近似于平行的类 球形泡壳。
——所述的第二颈体上端呈中心凹下的喇叭形圆锥面， 喇叭形圆锥面 外缘与罩壳融封连接。
——所述的灯头是由绝缘材料注压成型的整体结构， 电弧管第一颈体 与套在其外的罩壳的延伸部分嵌埋入灯头前端面并通过粘合剂与灯头固 定， 灯头前端面上设有不少于三根嵌埋固定的支撑销杆， 各支撑销杆的嵌 埋端在与灯罩壳呈同心圆的圆周上等距离分布， 另一伸出端分别与套在罩 壳上的金属夹持环上的对应焊接翼固定连接。
本实用新型的罩壳与类球形电弧管管壁之间的距离比较均勾， 故可使 电弧管温度分布均匀， 灯的热稳定性得以改善， 从而使灯的光电参数更为 稳定， 还可延长灯的使用寿命。 同时由于罩壳与电弧管对应部位的管壁与 电弧管类球形管壁近于平行， 电弧管点燃时所发出的光在罩壳内壁面近乎 垂直入射， 故可使更多分额的光直接透过罩壳辐射出去 （参见图 2)， 减少 了在罩壳内壁与电弧管外壁之间多次反射而散向四周及两端的杂散光， 提 高了光利用率， 减少了眩光。 此外， 本实用新型罩壳球泡两端直部直径减 小， 重量减轻， 提高了整体抗震性能。
本实用新型的灯头可用耐高温耐高压的绝缘材料浇注压制成型， 成型 时支撑销杆的根部已预埋固定在灯头模中。 灯头前端面要预留电弧管颈体 和罩壳的插孔， 组装时先将电弧管第一颈体和罩壳的延伸部分***灯头前 端面插孔， 用耐高温无机胶固定， 再将根部预埋在灯头中的支撑销杆与套 在罩壳外的金属夹持环焊接翼焊接固定。 本实用新型的电弧管和罩壳与灯 头之间采用胶固和由夹持环及支撑销杆组成的支撑架双重固定措施， 可使 灯的抗振和抗冲击性能得到明显加强， 而且具有结构简单、 装配容易、 成 本低等特点。 本实用新型中电弧管上端做成喇叭形再与罩壳封口连接的方 式可减少散向上端的眩光， 还可缩短灯体的整体高度， 减轻灯管重量， 提 高抗震性能， 而且易于通过传统的封口工艺生产加工。 本实用新型特别适 宜于作车辆前照灯， 还可用于机车、 飞机等交通工具的照明或作为特殊投 射光源并用于水下、 矿井、 厨窗以及用于对照明要求较高的其他场所。 附图说明

具体实施方式
下面结合附图与具体实施方式对本实用新型作进一步详细描述： 本实用新型部件包含： 电弧管 1、第一颈体 2a、、 第二颈体 2b、第一电 极 3a、 第二电极 3b、 第一电极引出线 4a、 第二电极引出线 4b、 罩壳 5、 罩 壳中部球泡 5a、第一电极引线 6、第二电极引线 7、第二电极引出线与第二 电极引线间的连接头 8、第二电极引出线外的瓷套管 9、夹持环 10、焊接翼 10a、 半环形焊接翼 10b、 支撑销杆 11、支撑销杆加固环 12、 第一电极引出 线外接端 13、第二电极引出线外接端 14、灯头 15、插柱体 15a、柱形槽 16、 中心插孔 17。
本实施例电弧管 1呈大致椭球状， 电弧管两端设有互成 180度角的直 径收縮的第一颈体 2a和第二颈体 2b，该二颈体均呈密封状态， 电弧管 1内 的第一电极 3a、第二电极 3b分别通过封嵌在对应端颈体中心的钼片及钼棒 材质制成的第一电极引出线 4a、第二电极引出线 4b伸出电弧管外并与第一 电极引线 6、第二电极引线 7电连接，两电极引线分别与设在灯头上的第一 电源连接端 13， 第二电源连接端 14电连接。 电弧管 1和设在颈体 2a外的 罩壳 5下部的其直径收缩部位密封连接， 第二颈体 2b上端制成中心下凹的 喇叭形圆锥面 2c， 喇叭形圆锥面 2c的外缘与罩壳 5封口连接。
灯头 15是用耐高温、 高压的绝缘材料压制成型的一体化结构， 电弧管
1的第一颈体 2a与罩壳 5的延伸部分均嵌入灯头 15端面中心部位的柱形槽 16 '内，并通过耐高温无机胶与灯头 15固定。在罩壳下端收缩部位下方的外 壁上套有金属夹持环 8，在金属夹持环 8外均勾地设有四个向外伸出的焊接 翼 10a以及半环形焊接翼 10b,总数为四的焊接翼 10a及 10b分别与根部预埋 在灯头 15端面中的对应支撑销杆 11的伸出端悍接连接， 支撑销杆 11的预 埋端在灯头 15端面上并在与罩壳 5呈同心圆并且半径大于罩壳 5的半径的 圆周上均勾排列。
金属夹持环 10可由两个半环形金属环扣合组合而成（见图 7)，每个半 环形金属夹持环中部设有向外伸出、 外端带孔眼的焊接翼 10a,半环形金属 夹持环两端设有向外延伸的、外端带半个孔眼的半环形焊接翼 10b,两个半 环形金属环组成闭合金属夹持环 10夹持罩壳 5外壁。 夹持环 10亦可为由 四个四分之一圆的弧环构成，见图 8，或为由一整根金属条带制成的整环（见 图 6)， 支撑销杆下部亦可加焊一个圆环使之成为一个整体， 从而进一步提 高了放电灯的整体稳定性和抗震性能。
灯头 15后部设有直径缩小的台阶形插柱体 15a， 第一电极引线 6从位 于灯头 15前端面柱形槽中心部位的预留中心插孔 17***穿过灯头 15， 从 灯头 15后部设在插柱体 15a内腔中心轴线上的插棒中心插孔 17伸出， 并 与套在插棒外的第一电源连接端 13电连接， 伸出第二颈体 2b的第二电极 弓 I出线 4b在引出电弧管后即折向灯头方向经连接头 8与第二电极引线 7连 接后以与电弧管轴线大致平行的方向穿过灯头上的孔与外接端 14电连接。 第二电极引线 7外套有瓷绝缘导管 9，瓷管 9的下端安***灯头中用绝缘胶 固定。
在罩壳 5中部与电弧管 1的类球形泡壳相对应的部位即罩壳中部球泡 5a设有向外鼓出、 且与电弧管 1球泡面呈近似平行的类球形泡壳。 与通常 · 采用的直筒形罩壳相比， 这种结构使罩壳 5的罩壳中部球泡 5a部位与电弧 管 1各部位之间的距离比较均匀， 故电弧管 1温度较为均匀， 灯的热稳定 性和光电特性得以改善， 并能延长灯的使用寿命。 更重要的是由于罩壳 5a 设有与电弧管 1外壁近于平行的曲面， 电弧管 1点燃时所发出的光垂直射 向罩壳中部球泡 5a内壁面， 故可使更多的光直接透过罩壳 5的罩壳中部球 泡 5a辐射出去 (参见图 2，而在直管形罩壳情况下，电弧管辐射出的光到达罩 壳表面时， 由于入射角较大,一部分光在罩壳 5内壁与电弧管 1外壁之间多 次反射而成 向四周及两端的杂光（参见图 3)。 显然， 本发明提高了光利 用率， 减少了眩光。
