What you should know about the different types of LED dimming system

Are all LED lamps dimmable?

Not all LED lamps or bulbs are dimmable. To know if it is dimmable or not, it is necessary to look at the characteristics of the product or in its defect in the packaging.

What type of LED regulator do I have to buy?

If our LED lamp is dimmable, the next thing we should know is which regulation system it is compatible.

There are several ways to regulate the LED light of a lamp, below we detail the types of regulation currently used.

TRIAC (Phase Cut)

The TRIAC regulation is very simple and no additional cables are needed. It is a phase cut regulation, so it cuts the 230v signal that enters the lamp or bulb driver. The driver receives that voltage and regulates the light depending on the information received.

The TRIAC or phase cut regulation is perfect for regulating single-color LED lamps or bulbs in alternating current. At low light intensities, flickering may occur.

1-10V

The 1-10V dimming system bases its operation on the variation of the direct current through an analog signal, this allows a regulation of 1 to 100%, smoother, progressive and without flickering, better in most cases than the TRIAC regulation.

The 1-10V regulation requires L and N power plus two additional cables with polarity "+" and "-" that control the analog signal.

PUSH

The Push dimming system is controlled by a conventional push button (does not need any type of additional regulation pad). With a quick press the lamp turns on, and with another quick press the lamp turns off. If it is pressed and held down, the light intensity increases, if we release and keep it pressed again the regulation would decrease.

Push regulation must be carried out with conventional push buttons (without pilot). You need L and N power plus an additional cable back to the button.

DALI

DALI is an advanced regulation system. It can be connected with home automation systems, requires additional wiring and specific software. It is connected to a DALI control unit that manages the light of a complete installation.

You can group several luminaries into groups or scenarios. Or program each luminaire in a personalized way.

Recommended for large installations, requires specific knowledge about the DALI protocol.
