Claim 0:
1. An industrial emergency lighting device having a storage mode triggering circuit, comprising:
a driving module connected to an external power source;
a light-emitting module connected to the driving module;
a charging module connected to the external power source;
a rechargeable power source module connected to the charging module and the light-emitting module;
a power supply detecting module connected to the external power source; and
a control module connected to the driving module, the power supply detecting module and the rechargeable power source module;
wherein the power supply detecting module is configured to detect an input voltage of the external power source, wherein when the control module determines that the input voltage is low-level, the control module is configured to trigger a storage mode counting process, wherein when the control module determines that a number of voltage changes of the input voltage reaches a predetermined number of times during a predetermined time period, the control module is configured to enter a sleep mode wherein the charging module is connected to the control module via the power supply detecting module, wherein the power supply detecting module is configured to detect a charging voltage of the charging module, wherein when the control module determines that the charging voltage of the charging module is low-level, the control module is configured to trigger the storage mode counting process, wherein when the control module determines that a number of voltage changes of the charging voltage of the charging module reaches the predetermined number of times during the predetermined time period, the control module is configured to enter the sleep mode.
