Embodiment Construction

[0021] figure 1 It is a structural block diagram of the fire emergency lighting equipment of an embodiment. Such as figure 1 As shown, the fire emergency lighting equipment includes at least two main power sources 102 , a backup power source 104 , lamps 106 , and a power control circuit 108 .

[0022] Wherein, each main power source 102 is connected to a general lighting power supply circuit, and the backup power source 104 is a storage battery. When the main power supply is working, it also charges the backup power supply 104 .

[0023] The power control circuit 108 is connected to each main power source 102 and backup power source 104 . When the working voltage of the currently working main power supply 102 is less than a preset value, the power control circuit 108 controls another main power supply to be connected to the lamp; 108 controls the backup power supply 104 to be connected to the lamp.

[0024] Wherein, the currently working main power supply refers to the ma...

Abstract

The invention relates to a fire-fighting emergency illumination device comprising at least two main power sources, a standby power source, a lamp and a power source control circuit connected with thestandby power source and each main power source. When working voltage of one main power source in current operation is lower than a preset value, the power source control circuit controls the other main power source to be connected with the lamp; when working voltage of all the main power sources is lower than the preset value, the power source control circuit controls the standby power source tobe connected with the lamp. In the fire-fighting emergency illumination device, at least two main power sources and one standby power source are arranged; when the working voltage of one main power source is excessively small, operation is performed to switch to the other main power source; when the working voltage of the both main power source is excessively small, the standby power source is employed; via arrangement of a plurality of main power source, a phenomenon that the standby power source is employed immediately when one main power source malfunctions can be prevented, and reliabilityof the fire-fighting emergency illumination device can be increased.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire emergency lighting equipment. Background technique [0002] When dangerous situations such as fire occur, fire fighting equipment is an important sign instructing people to escape. For this reason, fire-fighting equipment should be in a standby state at all times to cope with emergencies at any time. For this reason, a main power supply and a backup power supply are usually provided, and when the main power supply fails, it can be switched to the backup power supply. [0003] If the main power supply fails, after starting the backup power supply, if the backup power supply is exhausted or the backup power supply fails, the fire emergency lighting equipment will not be able to operate normally, resulting in reduced reliability of the fire emergency lighting equipment. Contents of the invention [0004] Based on this, it is necessary to provide a fire emergency l...
