Problems solved by technology
In order to ensure the effect of evacuation indication, the emergency sign lights are generally always on, while the traditional emergency sign lights mostly maintain a fixed brightness. People are easy to get used to this brightness visually, and it is difficult to attract attention, and the emergency indication effect is poor.

The invention relates to an emergency marker lamp and a lamp management system. The emergency marker lamp comprises a control device, a plurality of light-emitting units and switching circuits, wherein the number of the light-emitting units is equal to that of the switching circuits, one light-emitting unit corresponds to one switching circuit, one end of the light-emitting unit is connected withpower supply voltage, the other end is connected with the input end of the corresponding switch circuit, the control ends of each switch circuit are connected with the control device, the output endsof each switch circuit are grounded, the control device outputs a first level signal to the control ends of each switching circuit in a first working mode to control each switching circuit to be conducted, and the control device outputs a first level signal to the control end of the switching circuit of the first part in a second working mode, outputs a second level signal to the control end of the switching circuit of the second part excluding the first part, and controls the switching circuit of the first part to be switched on and the switching circuit of the second part to be switched off.According to the invention, the emergency indication effect can be optimized.
Description
technical field [0001] The present application relates to the technical field of lighting, in particular to an emergency sign lamp and a lamp management system. Background technique [0002] Generally, in factories, hotels, schools, units, and stairwells in residential areas, emergency sign lights will be set up for fire emergency evacuation instructions. In order to ensure the effect of evacuation indication, the emergency sign lights are generally always on, while most of the traditional emergency sign lights maintain a fixed brightness. People are easy to get used to this brightness visually, and it is difficult to attract attention, and the emergency indication effect is poor. Contents of the invention [0003] Based on this, it is necessary to provide an emergency sign lamp and a lamp management system that can optimize the effect of emergency indication in order to address the above problems. [0004] An emergency sign lamp, comprising a control device, a light-emit...
