Switching LEDs is very straight forward but dimming is a bit more complicated. There are different ways of dimming and the type of LED driver needs to be matched to the control system in use. We ensure that the fittings and drivers we supply work well together.
- Mains Dimming (Leading Edge)
This method of dimming is most commonly used for electronic low voltage transformers typically used for halogen lamps. Rarely used for LED fittings and frequently troublesome with LED.
- 1-10C Dimming
This method works for dimming dedicated LED ribbon when coupled to a 1-10V dimmable driver. It requires a separate two core ‘control’ cable to be run from the dimmer to the fittings driver.
- Mains Dimming (Trailing Edge)
Mains Trailing Edge dimming can be used to dim most dedicated LED fittings when coupled to a mains dimmable driver. No extra control cable is required.
DMX is commonly used for colour programmable fittings. The DMX signal is generated by a lighting control system and requires dedicated cabling between the controller and driver. DMX is generally used with professionally designed lighting control systems.
DALI (Digital Addressable Lighting Interface) has been more commonly found in commercial environments and is a digital system. It is very flexible in its deployment and use. As with the 0-10V system it requires a control cable, but with DALI this cable can be run between many fittings. DALI is generally used with professionally designed lighting control systems. We are increasingly using DALI in residential lighting projects for its superior dimming, flexibility, cost-effectiveness and simplified wiring structure.
