About the fire emergency lighting options:

1, fluorescent emergency lighting, special evacuation lighting the light source must have instantaneous point Kai characteristics, such as incandescent, rapid start fluorescent lamps, high-frequency fluorescent lamps, low-power tungsten halogen lamp, the review found that some of the large space of places such as stadiums, The warehouse stores and other evacuation emergency lighting as part of the standby lighting, with normal lighting uniformity, and select metal halide lamps as the light source, it is wrong. Halide is a high-strength gas discharge lamp, its filament from the cold state to the full luminance requires 4 to 8 minutes, while a sudden power outage need after 4 to 5 minutes cooling in order to start again, it can not meet the requirements of instantaneous light, cut Do not choose.

Evacuation marker lamps should be used in a dedicated lighting design often has the capacity Dimensions of the correct selection of the light source, and some even write the     exit light only in legend, the words "induction lamp" trouble. To know in the state of fire, in order to ensure the marker lamp smoke visible, sharpness, and lamps selection closely related. Common in public places if large malls, configured small size induction lights, exit lights, which will inevitably affect the induced effect. China rules "the Appendix c.3.11 c.3.13 table provides a convenient choice program, and should be read in conjunction with the project to be adopted.

3, "Emergency lighting and lighting evacuation signs, protective cover glass or other nonflammable material should be located," the provisions of the the Article "strong". Evacuation marker lamps use special lamps meet the requirements of its manufacturing standards. When the to evacuate lights as part of the normal lighting, in order to achieve the effect of the decoration, often used in normal lighting, lamp type, such as downlights, ceiling lamps, grille fluorescent lights, cove lighting, protective cover material of these lamps is often not non-combustible material, the design is not annotated drawing graphics with normal lighting there is no difference, it is caused by the violation of Article "strong".

Lamps capacity improper selection, often result in a breach of Article "strong" still need to adhere to the work room, such as a fire pump house, power distribution room, firewood motor room fire, "high regulation" requirements "should ensure that the normal illumination , "its" interpretation "to the site usually work surface normal working lighting Minimum illumination as the main reference to" industrial enterprises lighting design specification requirements. The investigation pumping station for 20Lx, the distribution room 30Lx, the control room 75Lx, diesel motor room reference "China regulatory 6.1.9.5 for 35 ~ 40Lx, continuously for 1 hour. "Low regulation" the provisions of the forthcoming "new low regulation" has been defined as "should not be 10% lower than normal lighting illumination." This requires that the design is not at liberty to hang up to two double-headed emergency lights, or arranged several light lamp factory, and should at least look-up table select, such as the height of 3 to 4 meters, an area of ??30 to 50 square meters of the engine room, if you choose with illuminated type factory lights, the unit area standard 10 ~ 12W / m, with reflector fluorescent lamp 3W / m, and energy-saving lamps is another matter.
