Shenyang emergency fire lighting Introduction to power supply mode of
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 level of the building and the power conversion time. In addition, the duration of emergency lighting and emergency supply It is also an important factor to consider in power supply design. There are many kinds of power supply, and you can select some or all of them as emergency power supply. For independently controlled emergency lights with their own power supply, direct power supply can be used. And Power Distribution Box Connection, power supply adopts special circuit. During 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, this circuit is prohibited to connect with the general lighting circuit.
The emergency lamp is a common emergency lighting lamp, which has a long emergency time and automatic power-off emergency function.

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 evacuation and flow of people in the building, and the design and effect of emergency lights need to be strengthened. Lighting and design are completely based on the feelings of the designer, so it is easy to have problems of unqualified design and violation of building regulations. Therefore, the influence of various factors must be comprehensively considered in the emergency design of fire lighting. It cannot 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.
