Introduction To Power Supply Mode Of Fire Emergency Light

The proper power supply mode of emergency light is a key link in power supply design. The design process of this link should consider the type and use of the building, the grade of the building and the power conversion time. In addition, the duration of emergency lighting and the characteristics of emergency power supply are also important factors to be considered in power supply design. There are many kinds of power supplies, and you can select some or all of them as emergency power supplies. For independently controlled emergency lights with their own power supply, direct power supply can be used. It is connected with the distribution box, and the power supply adopts the special circuit. During the construction and design, it is required to supply power by the special circuit of the power box. In order to prevent the emergency light from catching fire, the circuit is not allowed to be connected with the general lighting circuit.

Emergency light is a common emergency lighting lamp, which has a long emergency time and automatic power off emergency function. The emergency lamp has the characteristics of low power consumption, high brightness and long service life. The power switch and indicator light are designed for emergency lighting in the event of power failure in factories, hotels, schools, units and other public places. First of all, the stairwell is an important place for the evacuation and flow of people in the building, and the design and effect of emergency lights need to be strengthened. The lighting and design are completely based on the designer's feelings, which is prone to the problems of unqualified design and violation of building regulations. Therefore, the influence of many factors must be comprehensively considered in the fire lighting emergency design. It can not be designed according to the specific layout of the building, which meets the requirements of convenience, practicality, environmental protection and energy conservation. It not only conforms to the principle of fire protection requirements, but also conforms to the reasonable design concept of the platform.
