Dimmable Lighting

Dimmers are devices connected to a light fixture and used to lower the brightness of light. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control light output from resistive incandescent, halogen, and (more recently) compact fluorescent lights (CFLs) and light- mitting diodes (LEDs). More specialized equipment is needed to dim fluorescent, mercury vapor, solid-state, and other arc lighting.

Dimmable 1-10V

1-10V DIM ADJUSTING

Characteristics of 1-10V Dim Adjusting

In 1-10V dim adjusting, the driver generates an analogue signal of 1V (minimum) to 10V maximum, which reaches the dimmer switch which modulates it.
It is possible to do it with different types of dimmer switch (possibility of using PUSH).
It is possible to connect different types of sensors.
Dim adjustment is done in a smooth way reducing the chance of flickering occurring. This chance is always very slim when compared to other types of dim adjustment, such as phase cutting, for example.
DOES NOT generate noise.

Conditions for Use

Needs L and N power plus two additional cables with “+” and “-” polarity for the analogue signal.
The dimmer switch must be compatible with LED without indicator lights. The characteristics of the dimmer switch must be taken into account in order to know the maximum number of devices to be connected.
It is possible to reuse old technology 1-10V dimmers, as long as the manufacturer recommends it.
Dim adjusts from 1 to 100%. If no dimmer switch with ON/OFF function is added it will NEVER turn off.
It is NOT possible to dim adjust using a rotary dimmer switch from several points when a direct dimmer switch is in place. Several switches in parallel connected to a dim adjustment panel for 1-10V driver control via switch WOULD BE possible.
Allows for appropriate use with a variety of twilight sensors, presence detectors, motion detectors, etc.

Recommendations for use

New or existing installations, in which it is possible to install the control wiring.
When smooth dim adjustment is needed, generally controlled with rotary dimmer switch, without the presence of flickering.
When dim adjustment connected to twilight sensors or detectors of presence, movement, etc. is required (educational use, offices…)
Professional installations.

Dimmable PUSH Direct

PUSH DIRECT DIM ADJUSTMENT

Characteristics of PUSH Direct Dim Adjustment

In PUSH direct dim adjustment the driver internally adjusts its potentiometer 1-10V, working in the same way as 1-10V dim adjustment but controlled directly using a switch.
It must be done with conventional switches (there is NO need for any additional dim adjustment panels).
Dim adjustment is smooth thereby reducing the chances of flickering occurring. This chance is always very slim when compared to other types of dim adjustment, such as phase cutting, for example.
Desynchronisation may occur. This is usually reversed and generally by means of keeping it pushed down for a certain length of time or with a certain push sequence.
DOES NOT generate noise.

Conditions for Use

– It needs L and N power plus a return cable from the switch that is connected to PUSH L (normally). Also, depending on the driver, you may need an additional neutral input as shown in the diagrams.

– The switch must not have an indicator light.

– It is possible to reuse switches provided they are in good condition.

– It is possible to add several switches in parallel for dim adjustment from several points (controlling distances and synchronisation).

– It is possible to add several devices to the same switch. However, the greater the number of devices there are, the greater the possibility of desynchronisation.

– Always follow the instructions from the manufacturer of the driver.

– If you decide to add several devices, the switch return cable must enter each driver in parallel and must not be bridged from one driver to another.

– Dim adjusts from 1 to 100%.

DIM ADJUSTMENT USING PHASE CUTTING

Characteristics of Dim Adjustment using PHASE CUTTING

Dim adjustment is done by cutting the waveform from the network at the beginning (leading) or at the end (trailing) of the phase.
You can do it with different types of dimmer switch (option of using PUSH).
It can generate noise in the driver.
At low light intensities, flickering can occur (dimmer switches usually have a minimum selector). The minimum is normally set at 20%.

Conditions for Use

– It only needs L and N power. An additional control cable is NOT necessary.

– The dimmer switch must be LED compatible (from 0/4W – 100/200/… W).

– It is NOT possible to reuse old technology dimmer switches (from 40W to 200/400/… W).

– Dim adjustment recommended from 20 to 100% (below 20% possible presence of flickering)

– It is NOT possible to dim adjust using a rotary dimmer switch from several points when a direct dimmer switch is in place. Several switches in parallel connected to a dim adjustment panel WOULD BE possible.

– Limited use with sensors (it is NOT compatible with twilight sensors, it is generally used with “corridor” function)

Recommendations for Use

– Existing installations where NO wiring can be added.

– When you need to save on dim adjustment.

– Small and basic installations.

Dimmable DALI

Characteristics of DALI Dim adjustment

In DALI dim adjustment the driver is controlled digitally by means of specific software that transmits the commands to a DALI controller which transmits them through the DALI protocol to luminaires, blinds, doors, etc.
It allows you to control different elements of a house from the same point.
It allows you to control luminaires of the same circuit, jointly or independently. Each luminaire has an address within the system.
Dim adjustment is done in a specific way and a numerically determined value can be programmed.
It is possible to control luminaires through this system with sensors, control panels, dimmer switches, etc.
Each bus (two wires) can manage up to 64 devices in a maximum of 16 groups.
With DALI, desynchronisation is avoided
