Assembly halls come in many sizes, ceiling heights and with different production flows, ambient temperatures and varying degrees of automation. Lighting solutions for production halls need to be flexible to suit the needs of both automated work processes and detailed inspection work performed by people. Introducing lighting zones that are adaptable to different illuminance levels increases flexibility, as work processes may change rapidly.
Production hall employees have differing lighting needs. The solution can include dimmable task area lighting or additional luminaires where needed. Lighting requirements vary from the medium low illuminance levels in assembly halls and welding and forging areas to the higher levels required in precision machining and monitoring stations. Workstation lighting should be positioned above and slightly to the side of each workstation.
Linear or symmetrical LED industrial lighting products are the favoured option for production and assembly halls. Flexible systems that are easily adaptable to changes in work operations are the clear choice. A high IP rating is essential for use in dusty production hall environments. High-bay LED luminaires are suitable for areas with ceiling heights above 6 m.
