What is DALI Dimming

When more than one fixture needs dimming, we can use DALI dimming instead of 1-10V dimming. DALI dimming is a typical digital control mode.

DALI (Digital Addressable Lighting Interface) is an internationally-recognized lighting control communication protocol with a communication speed of 1200 BPS ± 10%. Mainly used for dimming control of multiple fluorescent lights and LED lighting. DALI can form a network with a maximum of 64 short addresses and 16 group addresses. A host can control one or more  computers and communicate in half-duplex mode.

Each of the four letters DALI has meaning:Digital, Addressable,Lighting ,Interface .DALI can dimmer each fixture with DALI driver. Different lighting units on DALI bus can be flexibly grouped to achieve different scene control and management. Compared to other dimming methods, the advantages of DALI dimming are:

• Digital dimming, dimming accurate, stable and smooth;
• Dali can communicate with each other in both directions, and can feedback the lamp to the system;
• Dali control is more flexible;
• Dali has strong anti-jamming ability.
