What is a DALI network?

Digital Addressable Lighting Interface (DALI) is a trademark for network-based products that control lighting. DALI is specified by a series of technical standards in IEC 62386. Standards conformance ensures that equipment from different manufacturers will interoperate.

How does DALI bus work?

HOW DOES DALI WORK? The core of DALI is a bus – a pair of wires that carries digital control signals from input devices (such as sensors), to an application controller. The application controller applies the rules with which it has been programmed to generate outgoing signals to devices such as LED drivers.

What is a DALI power supply?

DALI Power Supply is a a basic element of DALI installations and provides power supply for all DALI devices. It is fully compatible according to the DALI standard, and capable of supplying DALI devices with an overall current consumption of up to 250 mA.

What does DALI dimming mean?

Digital Addressable Lighting Interface
DALI (Digital Addressable Lighting Interface) These dimmer switches use a digital protocol to send a dimming control signal to a driver down separate wires to the mains supply. They do not directly control the energy passed to the driver. Lamps are never (directly) DALI dimmable.

What is the cabling length of a DALI bus?

The DALI bus carries DALI power and data on the same pair of wires, typically using standard 2-core cable (1.5 mm²). The polarity of the wires does not have to be observed, and free wiring topology is allowed. The maximum cabling length (the distance between the furthest-apart devices) is 300m.

How is a DALI network different from a DSI network?

The network can be arranged in bus or star topology, or a combination of these. Each device on a DALI network can be addressed individually, unlike DSI and 0–10V devices. Consequently, DALI networks typically use fewer wires than DSI or 0–10V systems. The bus is used for both signal and bus power.

What does Dali stand for in lighting system?

DALI stands for Digital Addressable Lighting Interface. It is a 2-way communications protocol that is used to provide control over, and communication between, the components in a lighting system. DALI originated in the late 1990s and was defined in IEC60929. Since then it has been substantially modified.

Which is the best definition of bus topology?

Definition – What does Bus Topology mean? Bus topology is a specific kind of network topology in which all of the various devices in the network are connected to a single cable or line. In general, the term refers to how various devices are set up in a network.
