Do You Know the Application Scenarios of Pick to Light System?
Pick to light system are intelligent devices that integrate IoT technology, e-ink display electronic labels or LED electrnic labels, and digital management. They are primarily used in warehousing, retail, and logistics for improving the accuracy and efficiency of the picking process.
The core function of pick to light system is to replace traditional paper labels with digital displays that provide real-time updates, enabling faster and more accurate order fulfillment. These systems can be applied in a variety of settings—let’s explore a few key application scenarios:
Wave Picking with Light Signals
Function:
The system lights up according to pre-set wave picking schedules, notifying operators when to start or finish a specific batch.
Advantages:
Streamlines wave separation, reducing time spent identifying tasks
Optimizes workflow and ensures timely completion of each wave
Reduces operational errors and increases accuracy
Application Examples:
Third-Party Logistics & Sorting Centers: In courier hubs, packages are sorted by destination or delivery company. Lighted electronic tags mark each area, boosting efficiency.
Cross-Border Bonded Warehouses: Multilingual display support enhances international team collaboration in global logistics operations.
Warehouse Light Picking
Function:
Lights are installed on shelves or in picking zones. When the system receives an order, the light corresponding to the correct item illuminates, guiding the picker directly to the item.
Advantages:
Improves picking efficiency by reducing item search time
Reduces picking errors and ensures inventory accuracy
Enhances the working environment by lowering physical strain on pickers
Application Examples:
E-commerce & Retail Warehousing: In large-scale e-commerce warehouses handling massive SKUs and orders, light guidance helps reduce walking paths and improves picking speed—especially in "goods-to-person" models.
Supermarket/Convenience Store Backrooms: For real-time fulfillment of online orders, particularly for perishable or time-sensitive goods, picking instructions are instantly updated on the system.
Electronic Material Call System
Function:
Operators can press a button on the pick-to-light label to request materials. The system then automatically sends the request to the appropriate department or warehouse.
Advantages:
Improves the timeliness and accuracy of material supply
Streamlines workflows by minimizing waiting and downtime
Enhances operational efficiency to meet production demands
Application Examples:
Automotive & Electronics Manufacturing: In component storage areas, digital tags display part numbers, batches, and quantities, helping avoid production line shortages.
Pharmaceutical Cold Chain Logistics: Medications are picked according to strict order requirements. Electronic tags can display temperature control prompts to prioritize refrigerated items.
The above are just a few examples of how pick tolight technology can be applied. As warehouse automation (such as smart warehouses and unmanned storage) and new retail models continue to evolve, smart picking tags are becoming a core part of the infrastructure.
Their key value lies in digitalization, automation, and data-driven operations. As IoT and automation technologies mature, pick-to-light systems will further penetrate the logistics, retail, and manufacturing sectors. While currently favored by large enterprises and high-end applications, these solutions are poised to scale down to SMEs in the near future—becoming a vital part of the smart supply chain.
