本发明涉及白炽灯及其零部件， 尤其涉及改进发光体固定支撑件结构的卤钨灯。 背景技术
现有技术各类单端卤钨灯由玻壳、 灯丝、 玻珠支架、 两片钼片、 两支钼脚等构 成； 玻珠支架与玻壳不接触， 它由一颗玻珠、 两根穿过玻珠两端的较粗的导丝及若干 根固定在玻珠上的支架丝构成， 灯丝中间由支架丝支撑， 灯丝两端分别与玻珠支架的 两根导丝连接， 再分别经钼片及钼脚从玻壳的一端引出。 这样的卤钨灯结构复杂、 制 作成本高。 为克服前述现有技术卤钨灯的不足， 业内人士研究开发生产了挑杆支架结 构的卤钨灯， 如图 1所示， 所述挑杆支架结构的卤钨灯包括玻壳 Γ、灯丝 3'、钼箔 4' 和引出脚 5' , 在玻壳 的内腔壁上连接有挑杆 2' , 所述灯丝 3' 从挑杆 2' 绕过， 再与钼箔 4' 连接。 所述挑杆支架结构的 钨灯在一定程度上解决了玻珠支架 钨灯 结构复杂等问题， 但仍存在以下不足之处： 由于钨丝的上下、 左右两个自由度得不到 限制， 因此钨丝高温发热后膨胀伸长容易滑至靠近玻壳的内壁， 一方面可导致玻壳内 壁黑化； 另一方面当接触到钨丝时， 玻壳将受热变形从而降低玻壳泡壁的耐压强度， 这样， 当被充以高压惰性气体时所述卤钨灯易发生爆炸而降低安全性能。 再者， 钨丝 偏离光学中心， 影响灯具的配光效果。 发明内容
本发明要解决的技术问题在于避免上述现有技术的不足之处而提出一种结构简 单、 灯丝定位可靠又不易滑动、 安全性能好的卤钨灯以及配备该卤钨灯的照明灯。
为解决上述技术问题， 本发明的基本构思为： 设计一种中空的支架结构来支承 灯丝， 使灯丝即使在发热膨胀伸长的情况下也不易滑动和不直接接触玻壳。
作为实现本发明构思的技术方案可以是：
设计、 使用一种中空管状支架结构的卤钨灯， 包括玻壳、 灯丝、 钼箔和引出脚， 所述玻壳的腔内固定有中空管状支架， 所述灯丝从所述中空管状支架的中间孔内穿 过，再于两端与所述钼箔连接；所述玻壳上端两对立面相向向内凹进形成两夹持突起， 所述中空管状支架被所述两夹持突起夹持固定。
所述中空管状支架为一圆管形玻管， 所述灯丝从所述玻管内穿过。
所述两夹持突起从所述玻管的柱面将玻管夹持固定。
所述中空管状支架为一螺旋管， 所述灯丝从所述螺旋管内穿过。
作为实现本发明构思的技术方案还可以是：
-设计、 使用一种中空环状支架结构的卤钨灯， 包括玻壳、 灯丝、 钼箔和引出脚， 所述玻壳的腔内固定有中空环状支架， 所述灯丝从所述中空环状支架的中间孔内穿 过，再于两端与所述钼箔连接；所述玻壳上端两对立面相向向内凹进形成两夹持突起， 所述圆环被所述两夹持突起夹持固定。
所述中空环状支架为一圆环， 所述灯丝从所述圆环内穿过。
作为实现本发明构思的技术方案还可以是：
设计、 使用一种直插式定向反射照明灯， 包括反射杯罩和用胶泥固定于该反射 杯罩光学中心的卤钨灯， 该卤钨灯包括玻壳、 灯丝、 钼箔和直插式引出脚； 所述反射 杯罩的杯口部被透镜封闭， 根底部用所述胶泥固定所述卤钨灯并伸出该卤钨灯的引出 脚； 其特征在于： 所述 钨灯的玻壳腔内固定有中空管状或环状支架， 所述灯丝从所 述中空管状或环状支架的中间孔内穿过， 再于两端与所述钼箔连接； 所述玻壳上端两 对立面相向向内凹进形成两夹持突起， 所述中空管状或环状支架被所述两夹持突起夹 持固定。
同现有技术相比较， 本发明中空管状 /环状支架结构的 钨灯的技术效果在于： 1. 采用中空管状或环状支架包括玻管、 螺旋管或圆环， 灯丝从支架的中间孔内穿过， 有效地防止了灯丝滑动， 避免了因灯丝紧挨玻壳内壁而导致玻壳黑化的现象， 而且， 灯丝始终不会偏离光学中心，使灯具的配光效果好；2. 玻壳避免了直接接触发热灯丝， 从而玻壳泡壁的变形小、 耐压强度高， 允许往卤钨灯中充入较高气压的惰性气体而保 持同样安全性能； 3. 结构简单、 制作方便、 成本低。
