Introduction
LED drivers are not only power supplies, they are also the communication link between fixtures and control systems. Protocols define how light can be dimmed, grouped or automated. Choosing the right protocol is essential for reliability, flexibility and future-proof installations.
DALI Protocol
DALI, short for Digital Addressable Lighting Interface, is the global standard for professional lighting in offices, schools and public buildings. It allows bi-directional communication, which means that drivers can both receive control commands and send feedback to the system. Features such as scene setting, grouping and energy monitoring make DALI a versatile choice for large-scale projects.
DMX Protocol
DMX512 is the leading protocol in entertainment, stage and architectural lighting. It can handle hundreds of channels simultaneously, making it ideal for RGB, RGBW and dynamic installations. LTECH offers one of the most comprehensive DMX ranges, from compact decoders to advanced DIN rail units, ensuring precise and reliable control.
0–10V Control
Still widely used in commercial applications, 0–10V is a simple analog control method. It is cost-effective and compatible with many traditional dimming systems, although it lacks the precision and feedback of digital protocols.
SPI Pixel Control
For installations that require pixel-level effects, such as LED strips with chasing or color-changing patterns, SPI is the protocol of choice. It allows designers to create highly dynamic visuals, from subtle fades to complex animations.
Bluetooth Mesh
Smart home and wireless control are becoming increasingly popular. With Bluetooth 5.0 Mesh, LTECH (under the Xiaolei brand) offers a full ecosystem of drivers and controllers that integrate seamlessly with apps, voice control and IoT platforms. This brings professional-grade lighting control to residential and retail environments.
Conclusion
Each protocol has its strengths. DALI is perfect for building automation, DMX for entertainment and architecture, 0–10V for simple cost-effective control, SPI for dynamic pixel lighting, and Bluetooth Mesh for wireless smart home integration. By offering a complete range, LTECH ensures that installers and designers always have the right protocol for the job.
