防爆灯应急照明分析

防爆环境的应急照明主要包括备用照明, 安全照明, 疏散照明, 和应急救援照明. 选择产品时, it’s crucial to choose with care. 以下, 我们概述了每种类型应急照明的关键参数, 包括照明水平, 切换次数, 和连续供电时间.

1. Standby Lighting:

Standby lighting is used temporarily in case of normal lighting failure due to malfunctions.

Illumination: Should not be less than 10% of the standard lighting levels. In critical areas like high-rise building fire control rooms, pump rooms, smoke extraction rooms, distribution rooms, and emergency power rooms, standby lighting must ensure normal operations.

Switch-over Time: Should not exceed 15 秒, and for business premises, it should be less than 1.5 秒.

Connection Time: Typically not less than 20-30 minutes for production workshops, with communication hubs and substations requiring connection until normal lighting is restored. High-rise fire control centers generally require 1-2 小时.

2. Safety Lighting:

Safety lighting is designed to ensure the safety of individuals in hazardous situations following the failure of regular lighting.

Illumination: 一般来说, it should not fall below 5% of normal lighting levels. For particularly hazardous areas, it must not be less than 10%. Medical and emergency care areas, such as emergency centers and operating rooms, require standard illumination levels.

Switch-over Time: Must not exceed 0.5 秒.

Continuous Power Duration: Determined as needed, typically around 10 minutes for workshops and several hours for operating rooms.

3. Evacuation Lighting:

Evacuation lighting is activated to facilitate safe evacuation in case of an incident leading to normal lighting failure.

Illumination: Not less than 0.5 lux; if using fluorescent lights, the brightness should be appropriately increased.

Switch-over Time: Not more than 1 第二.

Continuous Power Duration: At least 20 minutes for battery-powered systems, and for buildings over 100m high, at least 30 分钟.

4. Emergency Rescue Lighting:

Emergency lighting refers to the systems used by factories, businesses, and public institutions under special circumstances.

Illumination: Varies based on the site environment and scope of use, with different luminous flux levels selected to meet emergency lighting needs.

特征: Most emergency lighting devices are explosion-proof, 防水的, 且耐腐蚀, functioning well in harsh conditions, including corrosive environments, heavy rain, and dusty settings, and are highly resistant to impacts and vibrations.
