As shown in fig. 5, a schematic structural diagram of an emergency light fixture system provided in a fifth embodiment of the present invention is shown, where the emergency light fixture system includes: emergency light detection apparatus 1000 and load module 2000.
In this embodiment, the load module 2000 includes at least one emergency light fixture 400, and the load module 2000 is connected to the emergency light fixture detection device 1000.
The system includes the emergency lamp detection device 1000 in the above embodiment, and therefore has the same beneficial effects as the above embodiment, and is not described herein again.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for those skilled in the art, according to the idea of the present invention, there may be some switching points in the specific embodiments and the application scope, and as mentioned above, the content of the present specification should not be construed as limiting the present invention.
