Detailed Description
Fig. 1 is a block diagram of a fire emergency lighting device of one embodiment. As shown in fig. 1, the fire emergency lighting device comprises a main power supply 102, a standby power supply 104, a lamp 106, a power supply controller 108 connected with the main power supply 102, an emergency lighting controller 110 connected with the power supply controller, and a switch 112 connected with the main power supply 102, the standby power supply 104 and the lamp 106, wherein the switch 112 is also connected with the power supply controller 108.
The main power source 102 is connected to a general lighting power supply circuit, and the standby power source 104 is a storage battery. The primary power source is also operable to charge the backup power source 104.
The power supply controller 108 is connected with the main power supply 102, and when the working voltage of the main power supply 102 is smaller than a preset value, the power supply controller 108 controls the change-over switch 112 to connect the standby power supply 104 with the lamp 106, and meanwhile, control information is sent to the emergency lighting controller 110, and the emergency lighting controller controls the lamp 106 to switch to an emergency state.
Specifically, the preset value of the operating voltage of the main power supply may be determined with reference to a standard of a national fire lighting fixture. The change-over switch can be a two-way switch, and is connected with the main power supply and the lamp, or the standby power supply and the lamp. When the working voltage of the main power supply 102 is smaller than the preset value, the working power supply is controlled to be switched from the main power supply 102 to the standby power supply 104, so that the situation that the lamp cannot work normally and the standby power supply is not started due to the fact that the voltage of the main power supply is too low is avoided. And when the lamp is switched to the standby power supply, the lamp is controlled to be switched to an emergency state. The emergency state of different emergency lighting fixtures is different. Taking a fire-fighting lighting lamp as an example, in an emergency state, the fire-fighting lighting lamp is in a normally-on state. Taking a sign lamp as an example, the sign lamp is in a flashing state and indicates the direction.

When the lamp is in a normal state, the electric quantity consumption of the lamp is low, and the lamp automatically returns to the normal state, so that the resource consumption caused by the electric time consumption of the standby power supply can be avoided, and the electric energy is reserved for an emergency condition.
In another embodiment, when the operating voltage of the main power supply 102 is greater than the preset value, the power supply controller 108 controls the switch 1082 to connect the main power supply 102 with the lamp 106, so as to switch to the main power supply in time and charge the standby power supply at the same time.
In another embodiment, the emergency lighting controller 110 is connected to the fire controller 114, and is further configured to control the lamp 106 to switch to an emergency state when receiving a fire alarm signal sent by the fire controller 114.
Specifically, fire alarms are provided in various areas within the building, each fire alarm being connected to the fire controller 114, and when a fire alarm of the fire alarm is detected, the fire controller 114 sends a fire alarm signal to the emergency lighting controller 110, and the emergency lighting controller 110 controls the lamps to be switched to an emergency state to cope with the fire. Specifically, taking a fire-fighting lighting lamp as an example, in an emergency state, the fire-fighting lighting lamp is in a normally-on state. Taking a sign lamp as an example, the sign lamp is in a flashing state and indicates the direction.
In particular, the light 106 may be a fire light or a sign light. Wherein, fire control light plays the illumination effect, and the marker light plays the marking effect, for example, mark safety exit, safety exit direction etc..
Fire alarms are arranged in various areas in the building, each fire alarm is connected to a fire controller, when fire alarm of the fire alarm is detected, the fire controller determines the position of a fire difference point according to the position of the fire alarm giving out the fire alarm, forms an evacuation path and sends the evacuation path to each sign lamp to control the indication direction of each sign lamp. The emergency lighting controller 110 is further configured to control the sign lamp to switch the indication direction to indicate the correct evacuation path when the evacuation path direction of the fire controller 114 is inconsistent with the current indication direction of the sign lamp.
