The Basics of Smart Lighting System – DALI Dimming System

The Basic of Smart Lighting System ——DALI Dimming System Speaker: Jiaqi Chen, General Manager, MOONS' Japan Today I will introduce the basic construction of the DALI Lighting System. The system consists of LED drivers, lighting fixtures, controllers, dimmers, and computers. However, the architectural lighting system in a real project is more complicated than this basic system. There are three images of light fixtures shown, they include LED drivers, controllers, dimmers, and computers. The DALI controller, or DALI router, from HELVAR, connects to a computer through an Ethernet bus. The dimming signal line is connected to the LED driver dimming port. And DALI dimmer is parallel and connects to the signal line. The black wires are AC input lines. The DC output wires are on the other side of the LED driver. This is a single-channel LED driver. And this is dual channel LED driver that can control two fixtures respectively. That is the basic device of the DALI lighting system. So, how do you control and dim light? I would like to introduce you to the HELVAR dimming software. The light can be controlled either by dragging the sliding block on the software interface or by twisting the dimmer knob. That is all about a simple DALI system. Shown are the lighting fixture, LED driver, controller, and dimmer. It is convenient for us to control light and gradually be used in various lighting applications. Thanks for your watching!
