摘要： A torch particularly for use in hazardous conditions has safety and battery power warning features.
The supply from a power source (34) to a light source (12) includes a frangible conductive element (132) in the conductive path to the light source (12). The conductive element (132) is provided on a torch glass (128), so that if the glass (128) breaks, the power supply to lamp (12) will be cut off, thereby eleminating the risk of sparks, and exposure of the hot lamp element to atmosphere.
The torch also has a switch (22) and relays (38, 40) enabling batteries of the power source (34) to be switched between series and parallel arrays, enabling the torch to operate at full or low power.
The torch also has a battery voltage sensing and indicating means, which cause light source (12) to flash when battery voltage reaches a first predetermined level, and for the light source (12) to be switched off permanently when battery voltage reaches a second predetermined level.摘要翻译： 特别用于危险条件的手电筒具有安全和电池电量警告功能。 从电源（34）到光源（12）的供应包括在到光源（12）的导电路径中的易碎导电元件（132）。 导电元件（132）设置在割炬玻璃（128）上，使得如果玻璃（128）断裂，则灯（12）的电源将被切断，从而引起火花的风险，并且暴露于 热灯元素到大气。 手电筒还具有使电源（34）的电池在串联和并联阵列之间切换的开关（22）和继电器（38,40），使割炬能够以全功率或低功率工作。 手电筒还具有电池电压检测和指示装置，当电池电压达到第一预定水平时，使得光源（12）闪烁，并且当电池电压达到第二预定电平时，使光源（12）永久关闭 水平。
