    • A light device having a battery and lamp housing and a hinged top door. Batteries and a lamp holder are located within the housing and are accessible by opening the hinged top door. As the hinged top door is opened, a cam surface that holds the batteries in tight contact with the lamp holder moves away from the batteries, thereby releasing the tension holding the batteries in place within the housing. The batteries can therefore be easily loaded and unloaded. Likewise, as the hinged top door is closed, the tension holding the batteries in place is reapplied to the batteries to create a circuit for powering a lamp engaged with the lamp holder. Furthermore, the lamp engaged with the lamp holder is also accessed through the hinged top door.
    • 具有电池和灯壳体以及铰链顶门的灯装置。 电池和灯座位于外壳内,可通过打开铰链顶门进入。 当铰链顶门打开时,将电池与灯座紧密接触的凸轮表面远离电池,从而释放将电池保持在壳体内的位置的张力。 因此,电池可以容易地装载和卸载。 同样地,当铰链顶门关闭时,将电池固定到位的张力被重新应用于电池,以产生用于为与灯座接合的灯提供动力的电路。 此外,与灯座接合的灯也可通过铰链顶门进入。
