Zusammenfassung: | The utility model discloses an LED pulse type built-in flash lamp of an intrinsically safe explosion-proof camera, which comprises a shutter button, a synchronous circuit is arranged at the lower endof the shutter button, the lower end of the synchronous circuit is connected with a CPU, and one side of the CPU is connected with a current control circuit. The utility model relates to an LED pulsetype built-in flash lamp of an intrinsic safety type explosion-proof camera. Removing an original xenon flash lamp and a control circuit in the camera; a built-in LED pulse type flash lamp and a control circuit with a single-chip microcomputer are added. A xenon flash lamp and a high-voltage charging and discharging circuit of a common camera are not provided; a common camera becomes an intrinsicsafety type camera; the device is suitable for coal dust and explosive gas environments; the camera is simple in structure and suitable for accident evidence collection, environmental data collectionand the like in flammable an |
