The benefits of LED lighting are even brighter when connected to the Internet of Things (IoT) and leveraging sensors and cloud-based software. For example, instead of lighting unoccupied stacks, corridors and other zones, warehouse managers can wirelessly schedule and control facility lighting, so light is only turned on when and where it is needed. Presence-aware dimming can help detect the lack of presence or motion in an area of the warehouse, and automatically reduce the amount of electrical light needed. Consequently, facilities can realize greater energy and cost savings, which can be significant when compounded with the efficiency gained from switching to LED luminaires. For instance, DHL Supply Chain implemented Signify’s Interact connected lighting system in one of its largest US warehouses -- a 383,000 square foot facility in Lockbourne, Ohio that supports 60,000 to 85,000 transactions daily. The facility has outpaced its annual one-million-kilowatt hours savings target with a >50% reduction in energy use.
Taking sustainability one step further, connected lighting can be integrated with other smart systems in your facility, like your HVAC, to share data commands on a common network. The intelligence gathered from your lighting system can be used to streamline heating and cooling functions, which means you will no longer need to heat or cool underpopulated areas within your warehouse. Coupled with environmental sensing capabilities, which simplify temperature and humidity system adjustments, the system can detect natural daylight and adjust your heating/cooling or smart window shades based on your building’s needs. Your facility can use natural daylight to heat itself or block sunlight to cool the space.
Similar to environmental sensing, scene management, or adapting lighting according to specific tasks or the time of day, can help improve employee productivity and operational security. Light scenes can be adjusted to provide more illumination in areas with insufficient light levels, which can promote employee security and visual comfort. For instance, DHL Supply Chain created 75 different groups of luminaires throughout the warehouse and can customize the light levels in each of these zones. They can tailor settings according to the needs of different client programs and deliver the ideal light to support different work functions and security around the facility.
Beyond energy savings and security, connected lighting helps facility managers digitalize their operations for more effective decision-making and future planning, making long-term business sustainable, too.
