5.3 batteries of power :
The battery power can be divided into: Light bring battery , battery group , person who assign set up to concentrate on concentrate on battery group 3 kind that set up by oneself. Taking the battery and taking the power type emergency light by oneself promptly by oneself in the light, this way power supply reliability is high, it is convenient to change and increase and decrease rapidly, the circuit trouble has not been influenced , it influences the face to be small that the battery is damaged . Shortcoming investment heavy, lasting lighting time restrict by size of capacity, is it manage and maintain expecting much to run. Little that the light is counted that this way is suitable for meeting an urgent need , the installation is more scattered, the small building. The centralized or battery group power concentrating on setting up of dividing area, the advantage is that the power supply reliability is high, change rapidly, compared with the situation that take the battery way by oneself there is less investment, it is relatively convenient to manage and safeguard. The shortcoming is to need the special room, the trouble of the battery influences the area to be large, when supplying power in the distance long, the wire section is big, will increase the dawdling amount of copper, and the fireproofing question of the circuit should be considered. This way is suitable for meeting an urgent need the light is counted more, the lamps and lanterns are relatively concentrated, the larger building. So in the important public buildings , important underground building , should cooperate with emergent lighting power of other types and use sometimes, it is so comparatively economic and rational . Calculate building of standing etc. for such power and capacity when can meet the demandsing, can utilize this kind of power to be done for the emergent lighting power in this place .

5.4.Make the power up :
Namely the power supply way that is made up by two kinds of wanton or more than two kinds of power . Because the structure of above-mentioned several kinds power , degree of reliability are different , the demand for the system and range of application are different. So it is very difficult sometimes to only choose a certain emergent lighting power in reality and meet the demands, it is very difficult to accomplish and safe and reliable, economy is rational . It is essential to choose two kinds or emergent lighting power of more than two kinds.
Meet an urgent need lighting distribution system should establish one’s own system , guarantee it in case of fire , excision fire control after the load, system can supply power still. Capacity and power supply time are unrestricted that this way supplies power, conversion time is apt to meet the demands. But in the great calamity , its power supply reliability may be destroyed. So, as to only adopting this way to meet an urgent need in the larger skyscraper and some very important buildings lighting power is not enough, it is essential to be supplementary and strengthening that it is worthy of regarding generating set or the battery as meeting an urgent need that it is necessary lighting power .
Generating set supply power advantage of way to supply power capacity and time unrestricted basically power supply, weak point conversion time relatively long,

can’t is it light safely to used in and some have high expectations for conversion time place reserve to light. When is it use the place to needing , should it adopts to be emergent lighting lamps and lanterns is it light for the transition to make by battery. The skyscraper and some very important heavy constructions, should adopt this kind and make the power supply way of the lighting power as meeting an urgent need up by generating set and battery .
6.Conclusion:
In the real construction work, meet an urgent need choice , lighting of power should count according to layer of the building, scale, complexity , staying with floating personnel’s amount , production , use characteristic , fire degree of danger and important degree in the building in the building in the building , and the establishment situations of other emergency supply,etc., consider synthetically and carry on technological economic analysis to compare, choose the optimum emergent lighting power . Making the power way up has more than power of advantages of two kinds, the folk prescri ption shortcoming can be complementary. Though investment is relatively large, dependability is high, still generally adopt in the skyscraper and some very important heavy constructions.
