Dimming options/systems options

[gazdkw82]

I need to install 2x 600x1200 led grid fittings into a small office.

The occupant needs to have the option of dimming the light levels because of the nature of her work.

IV found a couple of fittings but not sure how I source the correct dimming option. Domestically, anything I have installed with a dimming function has just relied on the switch itself dimming the fitting. All the fittings iv found so far have DALI, 1-10v, switch dim, push button dim.

My question is, do you have to have these systems in place to use one of the options above? We use DALI here so I know that system has to be installed but unsure of the others.

1-10v is a good option with LED. wired as standard with a SELV pair down to a 1-10v dimmer switch.

And a 1-10v dimmer switch, do they usually require a neutral?

 

[Nigel]

Nope.

Ok so you buy a fitting with 1-10v dimming and then buy a 1-10v dimming switch and it will work?

Exactly.

No, the 1-10v signal is on a seperate pair of conductors.

You can get 1-10v dimmers which also incorporate a switch for the 230V supply or else you would usually need a seperate switch to turn the fittings on and off.

It's not obvious from the picture but this one from aurora switches the 230V supply by pressing the knob and gives a 1-10v signal by rotating the knob. 1 Gang 2 Way Rotary Dimmer - http://auroralighting.com/gb/ProductDetail/AU-DSPLED

So with a 1-10v fitting and a 1-10v switch, all I'd need to do is connect a control pair between the 2?

I'll just need to check I can physically connect a pair between the 2. It's a suspended ceiling so chances are the switch wiring will dissapear in conduit somewhere

would these work together ok?

Change of plan, bumped into our electrical technician who wants to use DSI dimming. I will have re- look at it all

Bit OTT for 2No light fittings!

JCC light fittings. Everything they do is dimmable and at 230volts
