Advantages of DALI-2

DALI-2 comes with new and strict interoperability guidelines.  these strict guidelines result from the new parts and features. They also ensure smooth compatibility between DALI components

With DALI-2 (IEC62386 V2) lighting control has been simplified further.like the wiring, addressing and so on. Now the switching and sensor devices that were normally locked to a proprietary control system, or contained within another protocol have been moved onto the DALI line. This increases freedom, availability and choice for the installers and customers as now they can choose from a large number of compatible products.

Advantages of DALI-2

The only worldwide standard for professional lighting control.

Easy installation: the mains voltage and the two DALI control wires can be routed together in the same cable → simplified wiring

Two-wire wiring: can be installed together with the mains (L, N, PE). The same wiring methods are supported.

Stable dimming function: digital control signal for all devices → no light fluctuations.

Flexibility: Each DALI operating device has its own address and can be individually controlled.

Distributed intelligence: Various operating parameters are stored directly in the DALI operating device (for example, scene value, group membership, fade time, power-on behavior, etc.).

Status feedback: Request information (defective lamps, brightness)

Flexibility – Group Concept: A group is a summary of lights. Each operating device can be assigned to one or more of 16 groups, which greatly increases flexibility over non-addressable, rigidly wired systems.

Flexibility – Scene concept: In each DALI operating device up to 16 different light values can be saved as scene value. This allows the recall of predefined lighting scenes without delay.

Logarithmic light resolution up to 0.1%: The dimming curve is adapted to the brightness perception of the human eye.

Fixed issues and Gaps Related to “VI”

DALI-2 embraces more detailed specifications and a dedicated system description. Therefore, your DALI-2 system is less prone to malfunctions and misinterpretations because its electrical tolerances have more precise specifications. Tighter test procedures allow for error corrections.

Compatible with older DALI system

You can successfully install your DALI-2 control gear in older DALI systems since DALI-2 was specifically designed for backward compatibility.
