Fire emergency lighting is fire evacuation and expand the necessary facilities for fire fighting, fire personnel security quick evacuation and firefighters entered the fire-fighting within the building has a very important role. But the author in the daily fire inspection found that many units of fire emergency lighting in the selection, design, install and use the existence of problems in the process, the makes fire emergency lighting to proper role. There are quite a few public places in this context or a blank, set fire emergency lighting and evacuation signage also lack the attention it deserves. Some units due to a lack of expertise, will fire emergency lighting equipment and civil emergency light, some units has no production license of the product, a manufacturer of flat installation location incorrectly, no proper role.

First, from the legal guarantee, the execution of the new national standards, laws and sectional specification has not been suspended. Although the 1993 implementation of the publishing industry standard GA54-93 of the fire emergency lighting General technical conditions ", and from 3 January 2000, new national standards published GB17945-2000 in the fire emergency lighting. In fact, the emergency lighting manufacturers and engineering acceptance staff on the implementation of new standards is not good, do not conform to the current production of standard products into the market and the large-scale use. At the same time, the State fire emergency lighting design, installation, acceptance phase, there is no corresponding sectional specification. Only in the current architectural design fire protection standard (hereinafter buildings》), the senior civil building design fire protection standard (hereinafter referred to as the "regulations"), the main specification of fire emergency lighting has made some of the settings. But it is not difficult to find these provisions also lack materialized and operability. Making fire emergency lighting performance in engineering design, installation, acceptance and use of the several links cannot be guaranteed.

Second, from the product itself, the domestic fire emergency lighting product range single, leading to the majority of fire emergency lighting units cannot be a reasonable choice. Now the international common fire emergency lighting in accordance with the power supply and control mode can generally be divided into the following seven types:

1. bring the power of independent control type

2, with power supply centralized control type

3, centralized power independent control type

4, centralized power centralized control type

5. slave power supply independent control type

6. the master and slave electrical set up control type

7. the master and slave power slave control type

But my fire emergency lighting products are relatively single form. At present the domestic products to bring the power of independent control type. According to statistics, this type of product in the domestic products accounted for 80% of the total. Developed in widespread use in a large project of centralized power centralized control of fire emergency lighting, in only a dozen enterprise production, product quantities only domestic production of the product the total amount of 10%, in short supply; comes with power centralized control, the master and slave power supply independent control type, and slave power supply centralized control and slave power slave controlled fire emergency lighting products in China, there is no proven products that do not meet the actual needs. Product structure issues cause many of them cannot be based on the works of the actual situation for reasonable selection, to the subsequent use of a congenital problems.

Third, the low position of emergency lighting installation technology is not widely used. Low level lighting technology is close to the ground or floor height provide evacuation emergency lighting for a new installation of the application of technology, and traditional high (overhead) installation technology, it has special advantages and unique. Generally felt that the low level of emergency lighting installation technology benefits, not only is it low maintenance, low costs and economic benefits of effective, more importantly, its long-term safety and reliability advantages. Traditional high emergency lighting installation techniques commonly used to have a higher ceiling of larger space and evacuation aisle of ceiling or wall distance ground one height of location, space and provide uniform illumination of the aisle, and walkways provide clear information and direction signs, generally using the traditional persistent emergency lighting and emergency signs 8 Watt charging lamp. However, in more limited space, such as with relatively low ceiling in the corridor, emergency lighting system provides high illuminance lows often as emergency lighting system, due to fire, close to the ground at the smoke less, oxygen, easy dispersal of human's natural reaction to the bent or crawl operations; on the other hand, the low position of emergency lighting system uses to emit penetrates smoke light-emitting diode light source, a standard incandescent lamp module and high brightness modules that can produce the ideal local high illuminance, making evacuation personnel easier to identify the evacuation of the aisle, quickly and securely find ultimate exports, therefore, low-lighting the fire and other emergency situations for the safe evacuation of people is important. The author of Rizhao city and district County all fire departments have 1300 more public gathering places and large office buildings investigated and found that almost no units choose low and emergency lighting systems. I think this happens because there may be three. First, the existing jiangui "," resistance ", on the low level of emergency lighting and emergency lighting system with high design and installation of suitable sites and do not make explicit provisions; second, the low position of emergency lighting technology itself has not been extensive promotion of relevant departments, including the design and construction of the units on this technology are not very understanding; third, the domestic low-emergency lighting products manufacturers, products have not been widely promoted and universal. Provision of relevant information, the low position of emergency lighting technology in the United States has been widely used. United States underwriter's laboratories UL has published guidance for low-bit install of sidewalk sign system of standards, in Europe, lower emergency lighting or lower emergency signs and composite high emergency lighting in various public buildings is widespread, and in initiating the fire emergency lighting in low-technology standards. So in this regard we have obviously lagging abroad.

Visible, fire emergency lighting as fire evacuation and fire officers entered the room to expand the necessary facilities for fire fighting, in China have not yet fully play its proper role. AuthorThat should take the following measures:

First, the existing national standards to ensure strict implementation of the relevant departments should enact a fire emergency lighting in the selection, design, installation and use of fire sectional specification, on buildings》, the doctrine of "complement the main specification. At the same time the development of effective implementation of these norms of legal provisions and requirements. Standard fire emergency lighting production, design, installation and use of units of behavior.

Second, the right to modify or supplement the jiangui "," the regulations "on the part of the fire emergency lighting, increased fire emergency lighting selection and installation of specific technical requirements, make reasonable selection to enforce.

3. States should encourage the fire emergency lighting manufacturer for technical transformation, promotion of new technologies, increasing product range, to use a wider choice of units.

IV. strengthening engineering electrical designers and fire safety audit personnel training to improve their professional skills in engineering design and review source we will be able to live off, stop design selection and other errors.
