DALI VS 0-10V

There're multiple dimming methods and switches available from vtecklite with different capacities to attain different results.
Want to know the difference between these DALI and 0-10v dimming options?

0-10V dimming
0-10V dimming methods work by transmitting a signal between 0 and 10V. As such, the output of the lamp is scaled, providing 100% light output. Naturally, 0V provides the least amount of light output.

0-10V dimming has been tested throughout the years and remains a simplified, but still reliable LED dimming control protocol.

Both the 0-10V and below 1-10V dimming method are categorised as an analogue method.
0-10V is easy to understand systems and commissioning does not require specialized knowledge. However, to get different control groups each group needs separate wiring. 0-10V does not support bidirectional communication, so if sensors are required, additional systems may be necessary.

1. Each device needs its own wiring, which makes installation quite tricky if the lighting control system is large and complex

2. A 0–10V system can accommodate around 10 luminaires per controller.

3. The signal goes only one way, from the dimmer to the LED driver or fluorescent ballast. Because there is no signal coming back from the lights, there’s no data on which to measure their performance, as with digital systems

DALI dimming
DALI is a dimming method which stands for “Digital Addressable Lighting Interface.”

It’s also an international standard which drives the process of how lighting installation should communicate with control and steering systems. Unlike the two dimming methods listed above, DALI is categorised as a digital method.

A good thing to remember is the independence of DALI from lighting manufacturers. This means it’s very possible to utilise different brands and components within the same system.

Every DALI system is made up of a controller and a maximum of 64 lighting components, such as a ballast.
Each of these components are provided a unique identifying address, with the controller capable of controlling these components as the DALI system transmits and receives data.

DALI is an “Open” protocol. As an open protocol, any manufacturer can create devices that communicate using DALI. For example a DALI driver from one manufacturer will work with control stations, sensors, etc. from any other manufacturer using DALI.

1. The DALI protocol is useful if luminaires need to respond to more than one input device (such as a wall switch and a daylight sensor).

2. DALI requires a lighting control cable, but the cable can be run between many fittings. In fact, one DALI network can accommodate up to 64 DALI ballasts.

3. DALI allows lighting controls to operate as stand-alone systems or be integrated into larger building management systems.
