    • A portable drakroom safelight which incorporates several features which enhance its usefulness in a darkroom. The portable safelight includes a lamp, a safelight filter, rechargeable batteries, a light sensor, and control means. The safelight filter filters all light produced by the lamp, thus making the safelight safe for use in a darkroom and with photosensitive materials. A surface mounting bracket or stand supports the portable safelight and includes a transformer for converting household electric current into low voltage direct current suitable for use by the portable safelight. When the portable safelight is removed from the mounting bracket it automatically switches to operate from the rechargeable batteries and its illumination level is automatically reduced. The lamp is automatically turned off or on when the light sensor detects the presence or absence of ambient white light. Other features include a proximity detector for detecting the distance between the lamp and an object and a low battery charge detection means and/or battery timer. A pullout or adjustable stand or neck allows the portable safelight to be easily pointed in any direction or moved to different locations.
    • 便携式拉手室安全灯,其中包含几个功能,可增强其在暗室中的有用性。 便携式安全灯包括灯,安全灯过滤器,可充电电池,光传感器和控制装置。 安全灯过滤器可以对灯泡产生的所有光线进行过滤,从而使安全灯安全使用于暗室和感光材料。 表面安装支架或支架支持便携式安全门,并且包括用于将家用电流转换成适合于便携式安全门使用的低压直流电的变压器。 当便携式安全门从安装支架上拆下时,它会自动切换到可充电电池的工作状态,并且自动降低照明水平。 当光传感器检测到环境白光的存在或不存在时,灯将自动关闭或打开。 其他特征包括用于检测灯与物体之间的距离的接近检测器和低电池电量检测装置和/或电池定时器。 拉出或可调节的支架或颈部允许便携式安全门轻松地指向任何方向或移动到不同的位置。
