Dimming Controls 

Whilst LEDs themselves are not dimmable, they can be made so using appropriate dimmable drivers and power supplies. Below provides some brief information about our standard dimming selection.

For further details about any of our dimmable controls, please get in touch.

1-10V Dimming

Also known as Analogue dimming protocol, 1-10V Dimming is one of the earliest and simplest electronic lighting control signalling systems. Essentially, the control signal is a DC voltage that varies between 1 and 10. The controlled lighting should scale its output so that at 10V, the controlled light should be at 100% of its potential output, and at 1V it should at 10% output. 1-10V dimming requires 2 additional wires to run the signal along, as well as the mains cable.

Suitable for: Larger commercial projects
Pros:  Smooth, consistent dimming for high numbers of lamps
Cons: Additional cabling makes retrofitting more complicated

DALI Dimming

DALI (Digital Addressable Lighting Interface) has been the industry standard for digital lighting control since 1996. It is a digital protocol that provides 256 levels of brightness between off and 100%, which is translated to a power level via a logarithmic dimming curve. This curve gives larger increments in brightness at high dimming levels and smaller increments at low dimming levels. Lighting scene control is a feature of this Dimming down to around 1% is possible using this type of dimming control, as well as lighting scene control.

Suitable for: Larger commercial projects
Pros:  Smooth, consistent dimming for high numbers of lamps
Cons: Additional cabling makes retrofitting more complicated

Mains Dimming

Also known as Trailing Edge dimming (sometimes called Triac). A Mains Dimming system has a lower minimum load than leading-edge dimmers. This makes it a better choice for dimming modestly sized low-powered lighting circuits such as those used by LED, and include other benefits for the user such as smooth, silent dimming control, without any buzzing noise. Phase dimming switches usually look like Push button type dimming using standard dimmer switches, although there are a number of more modern plates available.Using the best equipment you can dim down to around 5% using this type of dimming control.

Suitable for: Larger commercial projects
Pros:  Smooth, consistent dimming for high numbers of lamps
Cons: Additional cabling makes retrofitting more complicated

DSI Dimming

The Digital Serial Interface (DSI) enables DSI enabled electronic drivers from Tridonic to be controlled. The luminaires are switched and dimmed using a two-wire control pair independent of the power supply cabling. In contrast to DALI, however, it is not possible to address individual drivers or ballasts separately. The low-voltage cable of the digital interface is polarity-free and can therefore be connected with either polarity to the DSI connection of the ECG. If the room layout is changed only the control line needs to be rerouted; the load line can be left unchanged. On/off switching is controlled via the digital interface.

Suitable for: Larger commercial projects
Pros:  Smooth, consistent dimming for high numbers of lamps
Cons: Additional cabling makes retrofitting more complicated

Switch DIM

This is a simple implementation of digital dimming suitable for small installations but still providing smooth dimming to 1% typically. Switching is achieved digitally so each light fitting is connected to an un-switched mains supply and additional single or two core control cable is then wired to retractive wall switches. Switching is activated by pressing the wall switch to turn the lights on or off. Dimming level is adjusted by pressing the switch until the desired light level is achieved.

Suitable for: Larger commercial projects
Pros:  Smooth, consistent dimming for high numbers of lamps
Cons: Additional cabling makes retrofitting more complicated

DMX 

Stands for Digital Multiplex and isa standard for digital communication networks that was originally intended as a standardised method for controlling light dimmers for stage lighting and effects. DMX has also expanded to uses in non-theatrical interior and architectural lighting, being the primary method for linking controllers (such as a lighting console) to dimmers and intelligent lights. Recently, wireless DMX adapters have become popular especially in architectural lighting installations where cable lengths can be prohibitively long. DMX should allow you to dim almost to extinction.

Suitable for: Larger commercial projects
Pros:  Smooth, consistent dimming for high numbers of lamps
Cons: Additional cabling makes retrofitting more complicated

Corridor Function

This sensor-based system operates the light on low intensity until presence is detected, then it increases to full brightness for a set period of time before automatically dropping the lighting level again once the presence has passed. An energy efficient system ideal for environments that require temporary illumination for through-travel.

Suitable for: Larger commercial projects
Pros:  Smooth, consistent dimming for high numbers of lamps
Cons: Additional cabling makes retrofitting more complicated
