Abstract

组合式白炽荧光手灯包含有前端部分(2)，手柄 部分(3)和基座部分(4)，前端部分(2)内装有白炽灯 管和反光罩，基座部分(4)内装有荧光灯管(6)。基座 部分(4)借助于可转动铰链(5)可以转过180°，这 样，可以利用前端部分(2)作基座，荧光灯管(6)可以 被放置得成一角度，以便在任何特定使用场合产生最 佳的照明。

Description

本项发明属于组合式白炽荧光手灯。
过去曾经提出过多种手灯，它们包括一个白炽灯泡和一个荧光灯管，白炽灯泡和反射罩结合起来以产生能够定向的光束，而荧光灯管可加以通电以产生一般的漫射照明。特别是，以前所推荐的手灯含有一个通常为长矩形的壳体，其中装有白炽灯泡和反射罩，用来从一端使光束定向，此外，在壳体的一个侧面上装设荧光灯管。
根据本项发明，组合式白炽荧光手灯包含一个具有比较大的端面积的前端部分，下基座部分和上手柄部分，在前端部分内装有白炽灯泡和反射罩，上手柄部分通常从前端部分平行地向后延伸，并且用具有横向轴线的可转动铰链与后端部相连接，而含有荧光灯管的下基座部分可以绕着可转动铰链进行转动，使得下基座的前端部从手灯的前端部分脱开，并且可以在大致为180°的圆弧内转动到任意位置，这样，对于特定的使用场合，可以将荧光灯管旋转到所需要的位置，以便得到最佳的照明。
这样，在宽大的前端部分内，反光罩直径可以调节，对于宽定向光束，反光罩直径希望大一些，当着使用荧光灯管进行照明时，宽大的前端部分可以为手灯提供稳定的基座。如果将手灯基座部分转过180°，并且在此位置从水平工作面沿手柄部分的长度向上放置，则具有竖立在水平工作面上的前端部分的荧光灯管，可以提供向前的定向照明，如果基座部分转过的角度小于180°，则荧光灯管可以提供部分或全部向下的定向光线，这种光线对于阅读放置在工作面上的资料可能是最适宜的。
最好，手灯的电池盒装在手柄部分。为了方便起见，在手灯上还设置插孔，以便接入电源导线，如与机动车辆上的点烟器相连接。
通过实例，利用图解法将本发明表示在附图内，其中：
图1，根据本发明，是组合式白炽荧光手灯的侧示图;
图2是图1上手灯的前端示图;
图3是图1上手灯的后端示图;
图4是图1上手灯的顶示图;
图5是图1上手灯的底示图;
图6是相当于图1的示图，然而手灯倚着其前端立放着，并且表示出手灯基座部分可供选择的位置;
图7是沿图6箭头Ⅶ的方向得出的示图，并且基座部分处于极限升高位置。
参照附图，手灯1含有前端部分2，手柄部分3和基座部分4。如图2所示，前端部分2在透明玻璃后面装有白炽灯泡2a和反射罩2b，借此可以将一般向前的平行光束加以定向。
手柄部分3和基座部分4用具有横向轴线的可转动铰链5加以连接。
基座部分4的上面装有用半圆柱形的透明罩7所覆盖着的荧光灯管6，基座部分4的左端部，如图1所示，不与前端部分2相连接，这样，基座部分4借助于可转动铰链5能够转动到如图6所示的4a，4b，4c。4d和4e等位置的任一位置。根据特定的使用场合，也就是说，根据所要求的荧光灯管照明的特定类型，选定4a至4e中的一个位置。在位置4e，将从放置前端部分2的工作面上方的一个高度发出平行的定向光线，此高度相当于手柄3的长度，而在位置4c，将产生垂直向下对着工作面的定向照明。
如图3所示，电池盒装在封闭活板8的后面，在手灯处于图1所示位置的情况下，控制开关9装在手柄3的上表面，而插孔的插座10装在手柄部分3的侧面，该插孔用来从外部电源，如机动车辆的蓄电池，对电池充电或者使白炽灯泡2或荧光灯管6发光。

Claims (4)

1、组合式白炽/荧光手灯包含一个具有比较大的端面积的前端部分，下基座部分和上手柄部分，在前端部分内装有白炽灯泡和反光罩，上手柄部分通常从前端部分平行地向后延伸，并且用具有横向轴线的可转动铰链与后端部相连接，而含有荧光灯管的下基座部分可以绕着可转动铰链进行转动，使得下基座的前端部从手灯的前端部分脱开，并且可以在大致180°的圆弧内转动到任意位置，这样，对于特殊使用场合，可以将荧光灯管旋转到所需要的位置，以便得到最佳照明。
2、根据权利要求1所述的组合式白炽荧光手灯，其特征在于设有装在上手柄部分内的电池盒。
3、根据权利要求1所述的组合式白炽荧光手灯，其特征在于接有电源导线的插孔，以便与机动车辆的点烟器相连接。
