Emergency Light Manufacturers-Selection Of Fire Emergency Lighting Fixtures

1. The light sources of emergency lighting, especially evacuation lighting, must have the characteristics of instantaneous ignition, such as incandescent lamps, fast-starting fluorescent lamps, high-frequency fluorescent lamps, low-power halogen lamps, etc. In the review, some high-space places such as stadiums, In order to use evacuation emergency lighting as a part of the backup lighting in warehouses and other supermarkets, it is wrong to choose a metal halide lamp as the light source. Because the metal halide lamp is a high-intensity gas discharge lamp, its filament takes 4 ~ 8 minutes from cold state to full brightness, and a sudden power failure requires 4 ~ 5 minutes to cool down before restarting, so it cannot meet the requirements of instantaneous lighting. Do not choose.

2. Special evacuation signs should generally use special lamps, but the design often includes the correct selection of the capacity of the light source and the external dimensions, and some even just write the words "exit lamp" and "induction lamp" in the legend. It should be known that in order to ensure the visibility and clarity of the sign lamp under the smoke in the fire state, it is closely related to the selection of the lamp. We often find large shopping malls in public places, but they are equipped with small-sized induction lights and exit lights, which will definitely affect the effect of induction. Tables c.3.11 and c.3.13 of the "Civil Regulations" provide convenient options, which should be adopted in conjunction with the project.

3. "Emergency lighting and evacuation indication signs shall be provided with a protective cover made of glass or other non-combustible materials" as a "strength". Evacuation signs are made of special lamps, and their manufacturing standards have met the requirements. However, when evacuation lighting is used as part of normal lighting, in order to achieve the decoration effect, the same type of lighting as normal lighting is often used, such as downlights, ceiling lights, grille fluorescent lights, wire trunking lights, etc. The protective cover material of these lamps is often It is not a non-combustible material, and the design is not explained, and the graphics and graphics are not different from normal lamps, which results in violation of the "strong bar".

4. Improper selection of the capacity of the lamps often causes violation of "strong bar", such as fire pump room, power distribution room, diesel engine room and other rooms that still need to work during a fire. "High regulations" require "normal illumination "" Its "interpretation" is the same as the minimum illuminance of normal working lighting on the normal working surface of this part, mainly referring to the "Code for Lighting Design of Industrial Enterprises". It was found that the pump room was 20Lx, the power distribution room was 30Lx, and the control room was 75Lx. The diesel engine room was 35-40Lx for one hour in accordance with Article 6.1.9.5 of the Civil Code. There is no requirement for “low-profile”, and the forthcoming “new low-profile” has stipulated that “it should not be 10% lower than normal illumination.” This requires that the design cannot be hung with 1 or 2 double-headed emergency lights, or arranged several times. Factory lights, and at least check the table selection. For example, for a machine room with a height of 3 to 4 meters and an area of ​​30 to 50 square meters, if a photo-type factory lamp is selected, the unit area standard is 10 to 12 W / ㎡. Fluorescent lamps are about 3W / ㎡, energy-saving lamps are another matter.
