DALI stands for 'Digital Addressable Lighting Interface'. The DALI protocol is the worldwide standard for professional and digital control of lighting. All major lighting manufacturers have come to an agreement on how a lighting system should communicate with the control and operating systems. This is laid down by the IECC in the technical standard IEC62386. The DALI standard describes what manufacturers must comply with in order to manufacture DALI-certified equipment. Besides controlling lighting, the luminaires can also be easily monitored via DALI for, for example, energy consumption.
Helvar played an active role in the creation of the DALI protocol in 1999. As a member of the DALI Alliance Board, Helvar is closely involved in the developments of the protocol.
At 1200 bits per second, DALI is lightning fast. A requirement for lighting control; even a small delay could cause annoying situations.
Because each component in the software has a unique address, the system can be adapted and expanded at any time.
A DALI system is easy to install. There is freedom in cabling: star, loop-through or a combination is possible and a simple 2-wire cable can be used.
DALI is an open standard. Luminaires of all brands can be used interchangeably. DALI-2 control devices can also be exchanged.
A simple 2-core cable can be used for cabling. The maximum length of a DALI cable of 0.8 mm² is 100 metres and at 1.5 mm² it is 300 metres. It is also possible to combine the DALI cabling with the 230 V power supply in e.g. a 5-core cable.
With advanced software, a DALI system can be fully programmed. With the software, lighting can be divided into groups and commands and scenes can be controlled and read out.
DALI lighting is intelligent. A luminaire with a DALI driver is individually controllable and all kinds of smart functionalities can be assigned to it.
Besides the standard DALI functionalities, a manufacturer has the option to add additional functionalities within the guidelines. Therefore, Helvar has added extensive functionalities that simplify commissioning, increase reliability and capacity and optimise user comfort.
Standard DALI
DALI + Helvar
The DALI protocol has undergone a restructuring. Many new functionalities and commands have come out of this. One important change is that the certification of DALI components can no longer be done by manufacturers themselves but by the independent Digital Illumination Interface Alliance (DiiA) needs to be done. This ensures better-quality products.
| DALI | DALI-2 | |
| Number of DALI addresses | 64 luminaires | 64 luminaires/DALI controls + 64 DALI-2 controls |
| Interoperability of devices | No | Yes, but added value/functionality is not equivalent between manufacturers |
| Burn time readout | No, only by calculation | Yes, if the LED driver is certified according to chapter 253 (Device Type 52) |
| Reading out energy consumption | No, only by calculation | Yes, if the LED driver is certified according to chapter 253 (Device Type 52) |
| Verified test results by DiiA | No | Yes, listed on the DiiA website |
