- What is Dali?
- Dali Technology
- Dali Devices
Dali - Digital Addressable Lighting Interface (DALI) is a trademark for network-based systems that control lighting in building automation. The underlying technology was established by a
consortium of lighting equipment manufacturers as a successor for 0–10 V lighting control systems, and as an open standard alternative to Digital Signal Interface (DSI), on which it is based.
Dali is used to Control electronic ballasts & Lights in digital way individually. Analogue dimming is usually referred to as 1 - 10v dimming. In this case, a dc voltage is sent to the driver, which dims the LEDs in response to the voltage. With digital dimming, the driver receives a digital signal which tells it how to respond. The advantage of digital dimming is that fixtures are addressable. You can also have many more different levels of light output when using digital dimming and wiring also comes easy in Dali as shown below
Dali Chances:
- Dali has established in commercial, Residential, Offices,Industries,Hotels,Resorts and many more segments
- Dali has expand the functionality of existing lighting control like analog (1-10v) dimming
- With Dali Light dimming is possible from 1-100% and if required can included with coloured Lighting controllers also
- With multiple Brands are providing Dali Controllers at competitive prices , its now best time to adopt Dali in every property
Functions of Dali:
- On/Off Switchable Operation
- Setting the brightness value with tunable dimming
- Dimming via human perception
- Fading time for Scenes
- Control of Individual Devices & Groups
- Status Feedback (On/off,Brightness values,lamp/ballast failure)
Some of the Major Brands Supping Dali Controllers
- Philips Dynalite
- Lutron
- Leviton
- and many more
Wiring Protocol:
- 2 wires cable polarity free which can be connected to ballasts and Dali controller in a loop
- Dali Power and cable can be also connected together with 5 core cable
- Free wiring topology
- Controllers & Ballasts may be connected to different power supply phases.
- Use of standard installation cable of 1.5 sq mm
- Having 64 addressable Dali devices is in practice sufficient for stand alone single area lighting solutions.
- How ever in larger installations there might be a need for integrating ten or hundreds of Dali devices
- In Such cases different manufactures offers so called Dali gateways,which can network multiple Dali sub nets
- Feedback for Maintenance
- Automated for emergency test ,reporting & logging
- From individual to Central control & Monitoring
- Brands like Dynalite or lutron offers a backbone for integrated building control to combine Eg: Hvac,Shades & Lighting etc
