What are the requirements for lighting in common industrial places?
Embedded Files
Industrial lighting involves a wide range of places and operations, including fine processing in small workshops, heavy industrial production in tall workshops, and operations in flammable, explosive and other dangerous places. Lighting workers must According to the nature of different places and operations, the corresponding design is carried out to provide comfortable, economical and safe lighting for the staff.
Industrial Lighting Requirements
Industrial lighting should ensure the comfort and safety of workers under the condition of reaching a certain illuminance. Reasonable lighting should balance the lighting level of the entire ground area and working surface.
The main working area needs around 500 lux for the production line. Higher the lux value, and brighter the illumination. If the manufacturing process involves assembling delicate parts, we would recommend 600 to 1000 lux, which is much more demanding
Emergency Lighting (Accident Lighting) Requirements
Accident lighting meets: Under normal lighting conditions, it can start quickly and complete the function of emergency lighting. Factories must have emergency lighting and safety evacuation instructions.
Ref: Minimum illuminance to ensure personnel safety as specified by US factory lighting standards
Low risk, low activity frequency, illumination ≥ 5.4 LUX
Low risk, high activity frequency, illuminance ≥ 11 LUX
High risk, low activity level, illumination ≥ 22 LUX
A high degree of danger, high activity frequency, illumination ≥ 54 LUX

Hazardous area lighting requirements
Both the refinery and the tank plant have extremely complex plant layouts, with major light obstructions and work surfaces at various levels.
Overhead floodlights are installed in several locations outside the confines of the hazardous area to provide illumination for safe walking and some piece work. In other places where this system can not provide sufficient illumination, some scattered local lighting fixtures need to be installed, such as stairs, aisles, valves and metering areas.
The installation locations of these luminaires should be carefully chosen to avoid glare when viewed from different horizontal directions. Most local lighting fixtures have bulkheads or well-glass frames, use high-pressure or low-pressure gas discharge lamps, and are appropriate to the hazard level of the work and materials in the area.

Lighting requirements for cargo handling areas and stockyards
These areas are mostly used for the storage and transfer of containers or other large items, so light obstructions are again a major design issue. Since most obstacles are movable, fixed local lighting cannot be used.
Also, consider the movement of delivery trucks, forklifts, lift arms and gantry cranes. Floodlights installed on high poles, towers or construction sites can provide general lighting for locomotives on rails, vehicles on the road and the safe movement of workers, while local lighting for shipments is provided by the hoist frame. Flood lights on the finish. Because there will be vibrations at these positions, gas discharge lamps with better seismic performance are more suitable, but it should be noted that the fluctuation range of the control voltage cannot exceed the standard of the lamps, otherwise the lamps are extremely easy to break.
Port Lighting Requirements
For dock lighting, floodlights should be installed on the periphery of the boundary so that in the work area, where cargo is loaded and unloaded, the lights are not affected by obstructions. At low tide this arrangement may cast shadows on the decks of ships moored on the shore. So be sure to have flood lighting on the deck and on the crane boom.
Dock and deck luminaires must be resistant to marine salinity; commonly selected materials are die-cast aluminium, brass, stainless steel and other plastics. Also, make sure that the lighting on the side of the dock does not interfere with the navigation lights.
