Science Popularization | Analysis of the Relationship between Casambi Bluetooth Power Supply and DAL
As the intelligent lighting industry continues to evolve, customer attention is shifting from basic dimming functions toward the capabilities of LED drivers in luminaire management and system integration.
As a result, questions such as “Do Casambi Bluetooth drivers support DALI Part 251, 252, and 253?” and “Do they provide a DALI memory bank?” are being raised more frequently.
Taking these common questions as a starting point, this article aims to clarify how LED drivers handle data management and system integration in intelligent lighting projects.
Does the Casambi Bluetooth power supply support DALI Part 251/252/253 or DALI memory bank?No.
The Casambi Bluetooth power supply itself does not generate, store, or provide any readable DALI data. This is determined by its product positioning and system architecture.
The data for DALI Part 251, 252, 253, and the DALI memory bank are generated, stored, and provided by the DALI-2 / D4i dimming power supply itself.
What if a project requires both Casambi wireless control and DALI data reading?Replace the existing driver with a DALI-2 / D4i driver.
– Generate and store DALI data (Part 251 / 252 / 253)
– Provide full DALI memory bank support
Introduce a DALI controller or DALI gateway compatible with the Casambi ecosystem
– Enable wireless control
– Collect and transmit DALI data
What problems do DALI Part 251 / 252 / 253 solve respectively?
DALI Part 251, 252, 253, together with the DALI memory bank, define the data that a driver must provide to the system from different dimensions, including luminaire identification, energy consumption, operating status, and configuration retention.
The DALI memory bank refers to the ability of a DALI driver to store key configuration data locally, such as addresses, groups, and scenes.Its core value lies in ensuring that luminaires retain their original configuration and operating state even after power loss or restart.
Once the system architecture and responsibilities of each layer are clearly defined, the selection of the DALI-2 / D4i driver becomes the next critical step. This is because the DALI-2 / D4i driver not only determines dimming performance, but also directly affects the stability and integrity of Part 251 / 252 / 253 data and the DALI memory bank.
Shengchang DALI-2 / D4i LED drivers are designed to meet these requirements. While ensuring high-precision, stable, and flicker-free dimming performance, they integrate complete DALI data management capabilities and support continuous access to Part 251 / 252 / 253 data. This allows the system to reliably obtain luminaire identification, power, energy consumption, and operating status information, while preserving the flexibility of Casambi wireless control.
Based on the above analysis, it is clear that in projects requiring both Casambi wireless control and DALI data access, clearly separating the responsibilities of the control layer and the driver layer—and using a DALI-2 / D4i driver with full standards compliance as the system foundation—is currently the most practical and robust system architecture.
