Abstract

An emergency direction indicator comprises a shell which is composed of a bottom shell and a cap body, and the face side has a hollowed-out portion. A light conducting board is arranged in the shell, and the surface has a sign of predetermined character drawing which is displayed by the hollowed-out portion of the cap body. A strip luminescent diode is composed of the arranged luminescent diode on the elongated circuit board, which is arranged in the shell and at the side of the light conducting board. The light emitted by the luminescent diode diffuses from the side of the light conducting board. The power supply controlling circuit board is arranged in the shell for controlling the needed power supply of the strip luminescent diode. The accumulating unit is connected with the power supply controlling circuit board for storing the electric energy at usual time. When the external power supply is cut off, the needed power supply of the strip luminescent diode can be automatically supplied to make the sign of the light conducting board brightened. The utility model is convenient for installation without occupying the space, which makes the entire lamp box thin and the display surface is clear. The utility model can save electricity and have a long durability without constantly changing the luminous source.
