China has a number of factories in the manufacture of centralized power centralized control fire emergency lamps, but also our future emergency lights development direction. As for the self-contained centralized control type, independent control type, centralized control type and sub-parent power supply sub-parent control type fire emergency lamps and lanterns products are not mature enough to meet the actual needs. The light source that emergency lamp will tell from lamps and lanterns, can divide into fluorescent lamp, electron energy-saving lamp, illuminant, cold cathode is illuminated tube to wait.
Since the introduction of emergency lighting system in China's fire system in the last century, fluorescent lamp has been used as the main light source. Fluorescent lamp light source although illuminance is high, but energy consumption is big, failure rate is high, can be phased out gradually. In recent years, the new type of light source comes out continuously, the light source and the cold cathode luminescence tube emergency lamp begin to get the emergency lamp manufacturer to look forward to and the user's approval. Light source emergency lights that have passed fire department testing have become common. The illuminance of illuminance of illuminance of illuminance of illuminance to the ground is low, although the illuminance that it is to the ground when be in metre height does not reach live, but use for emergency lamp or very conspicuous.
The advantage of illuminant emergency lamp is life is long, the life of the emergency lamp that USES as illuminant can amount to tens of thousands of hours, can use year above commonly. It also has the advantage of low energy consumption. The current when lit is measured in milliamperes, which is much lower than the power consumption of ordinary lighting. Generally, our archives work in a regular way. For the sake of safety, the archivists hope to cut off the power after work. Once the power is cut off, if lighting is needed again, standby power for emergency lighting should be enabled.
