Abstract: An emergency lighting structure is disclosed. The lighting structure employs high brightness LED as light source supply and dry cells are used to provide current during emergency. A plug is secured to a socket and when AC is interrupted, a current detection unit detects the interruption to trigger the power of the dry cells. When the dry cells are exhausted, a capacitance detection unit detects the status of current supply to trigger flashing which is controlled by a flash control unit.

Abstract: A power supplying device for flashes includes a base having a bottom formed with two opposite grooves, a threaded hole vertically extending therethrough, and two threaded holes, at least a rechargeable battery having a top provided with two conducting terminals and a protuberance, an extension cord provided at one end with a plug engageable with a power socket of the battery and at another end with a socket, and a power cord having an end provided with a plug engageable with the socket of the extension cord and another end provided with a positive and negative wires each provided with a metal conductor. One of the wires has a buzzer. A circuit protecting switch and a metal conductor are fitted within a cylinder with the metal conductor partially projected out of an end of the cylinder. Another one of the wires is provided at an end with a metal conductor which is fitted within another cylinder and partially extends out of the cylinder.
