The invention relates to a light curtain for an anti-explosion elevator. The light curtain for the anti-explosion elevator comprises a transmitting terminal and a receiving terminal, wherein the transmitting terminal and the receiving terminal are connected with respective power supplies; each power supply is formed by connecting three same power supply circuits in parallel; the power supply circuits are formed by power supply management chips; the input ends of the power supply management chips are connected with input voltage; the output ends of the power supply management chips are connected with the transmitting terminal and/or the receiving terminal; and the power supply management chips are used for carrying out voltage-reduction output on the input voltage of the input ends. According to the light curtain for the anti-explosion elevator provided by the invention, the working current of the light curtain can be reduced.
