Factory lighting includes workshop lighting, factory lighting, warehouse lighting, aisle stair lighting, design room lighting, office area lighting, etc. The scope involved is relatively broad. Illumination requirements vary. Below we explain respectively based on requirements and experience.

A. Factory lighting requirements

Industrial lighting should ensure the comfort and safety of workers when reaching a certain level of illumination. Reasonable lighting should balance the lighting levels of the entire floor area and work surface.

1. The illumination range of industrial plant lighting mainly includes workshop lighting, factory lighting and warehouse lighting. Among them, workshop lighting requirements are higher, generally ranging from 400lx to 1000lx, factory lighting is preferably 200lx~300lx, and warehouse lighting is 50lx~100lx.

2. Emergency lighting (accident lighting) requirements

Emergency lighting meets: under normal lighting conditions, it can be started quickly to complete the emergency lighting function. Factories must have emergency lighting devices and safe evacuation instructions.

3. High-altitude floodlights are installed at several locations outside the danger zone to provide lighting for safe walking and some piecework work. In other places where this system cannot provide sufficient illumination, some scattered local lighting fixtures need to be installed, such as stairs, aisles, valves and metering areas.

B.Lighting requirements for cargo handling areas and stockyards

These areas are often used for the storage and transfer of containers or other large goods, so light obstructions once again become a major design issue. Since most obstacles are movable, fixed local lighting cannot be used.

C. Warehouse lighting fixtures must meet the following requirements:

1. To meet the requirements for warehouse lighting illumination, generally speaking, the floor illumination of the warehouse should not be less than 50 lux to facilitate the identification of cargo labels;

2. Realize intelligent control of the lighting system and realize dual-channel lighting in the warehouse. One channel can be turned off during the day and two channels can be turned on at night to achieve energy saving;

3. Explosion-proof lighting fixtures with waterproof, dustproof and anti-corrosion properties should be used to ensure the safe operation of the fixtures;

4. In order to avoid the increase in later maintenance costs and ensure timely maintenance and replacement of lamps, lamps with long life and high stability should be selected;

5. Consider lamps that can be restarted instantly to avoid too long lamp delays.

D. What is the lighting brightness standard for factory buildings?

Factory lighting brightness standards are as follows:

1. Lighting brightness standard for ultra-precision operations, design, drawing, and precision inspection is 3000-1500lux.

2. The lighting brightness standard for design room, analysis, assembly line and painting is 1500-750lux.

3. Packaging, measurement, surface treatment, and warehouse lighting brightness standards are 750-300lux.

4. The lighting brightness standard for dyeing, casting and electrical rooms is 300-150lux.

5. The lighting brightness standard for entrances and exits, corridors, passages, stairs, and toilets is 150-75lux.

6. The lighting brightness standard for fire escapes and outdoor power equipment is 75-30lux.
