Orange TV Dimming
Questions about dimming lighting crop up constantly, especially now with LED technology making it harder to dim. We cannot rely upon the old methods, a new trickier dawn has risen over the lighting world.
A rotary knob – which is mains dimming
A momentary switch – which uses a 1-10V signal
You need to know there are two types of dimmer module – leading and trailing edge. We'll explain their meanings in another episode, but remember their names.
A low voltage transformer will need to be designed and made to be compatible with either leading edge, trailing edge or both, otherwise there will be strobing.
LEDs as a generalisation currently seem to prefer a trailing edge dimmer modules.
LED's use drivers as their power supply unit. LEDs run at significantly lower wattages so standard dimmer modules are not sensitive enough for the loading of an LED circuit.
For LEDs you need an intelligent dimmer module that can pick up the lower loading and still dim.
If you are still using tungsten halogen, the combined wattage of the fittings on a circuit must be at least matched to the size of the dimmer module.
Here at Orange lighting we will guide you through the process of selection and adapt a switch plate to have the correct dimmer module where possible.
