Lighting Control Systems
Lighting Controls PDF Print E-mail

Lighting controls systems can really enhance good lighting making the subtleties and impact of the design easy to access.

Lighting schemes frequently use a number of individual lighting circuits which together create an overall effect. The intensity of the different circuits, the speed of dimming, even the colour of the light can combine to give magical lighting effects. Lighting control systems take away the complexity of the elements involved allowing users to access different pre-programmed lighting "scenes".

Home Cinema
One obvious application of lighting controls in the home is in the growing area of Home Cinema. It has become a bit of a Smart Home cliche to describe the pressing of one button to see the screen descend from the ceiling, the projector turn on, the curtains close and the lights dim, but Home Cinema really has opened people's eyes to the possibilities of lighting control systems in the house.

Other Applications
There are many other applications. Lighting controls can replace large arrays of manual dimmer switches and provide one button access to pre-programmed scenes for eating, reading, entertaining.

"Avenues" of light can be created for the night time

Multiple rooms or even whole house lighting schemes can be integrated. With systems allowing the user to turn off the whole house with one button and the convenience of remote controls, it is possible to lie in bed and switch off all lights in the house with a simple remote control.

"Avenues" of light can be created for the night time, so a scene can be created that just lights the route from a bedroom to the kitchen for example. Integration with other home control systems mean that this "avenue" can be intelligently triggered by motion rather than requiring a switch and for this motion sensitivity only to be triggered at certain times of the day.

Security
Lighting can be integrated into security schemes with lighting mimicing an occupied house. Again this can be programmed to be more convincing than a simle timer operated system. With some systems it is possible to "record" normal occupancy and play that back when required.

We'd summarise the benefits of lighting controls systems as offering:

  1. Ease of use
  2. Quality feel
  3. Convenience

Degree of Reluctance
One thing we admit here is that it's initially difficult for many people to see the application of lighting control systems in the home. People are worried by the thought of major rewiring exercises and the cost. It's also difficult to visualise the effects for a lighting scheme that doesn't yet exist. Yet those of our clients who have followed down this route are now fierce advocates of these systems. Our favourite quote?

"Why didn't you convince me to do this before?"

( a client for whom we have now retro-fitted a wireless control system to a lighting scheme we developed last year)

The Future
Maybe that last example points to the future of lighting control systems in the home. Wireless technologies will increasingly provide the benefits of lighting control without the necessity of major rewiring scehmes simply to add controls. On new build or major rennovations lighting control can be factored in at the start of a project - there are fantastic wired systems that we will continue to use because of their power and flexibility.

Following a recent job where a client complained "Why didn't you convince me to put lighting controls in earlier?" we're going back to each of the main technology areas we work with to look at the benefits of each.

In this section we focus on Lighting Control Systems - what they do, why you might use them and why they are sometimes overlooked in residential projects. These systems are often referred to as mood lighting, but they offer a lot more than that.

Read here why we believe Lighting Control Systems enhance a lighting design project

 
Overview of Rako Controls PDF Print E-mail

We use a variety of lighting control systems but we design and commission a lot of systems that feature Rako controls. Rako is easy to use, it integrates with other systems well and yet offers great functionality when deployed in isolation.

It can be integrated with Audio / Video systems, Curtain and blinds systems, even whole house control systems. Rako can be used to provide fine control over lighting, curtains and powered screens in a home cinema room or can offer the ability to switch off all the lights in a house at the touch of a single button. So it's versatile and well supported, but why might it work for your project?


When do we use Rako
We particularly like using Rako lighting control system when clients have the following criteria:

  • Where the lighting control system is being retro-fitted in to an existing house. The wireless technology minimises the amount of electrical work and ‘making good’ required, and there is no need to take all of the wiring back to a central point.
  • Where a high degree of flexibility of control over freestanding light fittings is required. You can for example keep including different floor or table lamps in to your lighting scheme without the constraints of a 5amp circuit. This is particularly important in rooms which will change use over time, or where the installed lighting doesn’t give you any flexibility over moods (eg; where is it a single circuit pendant or grid of downlighters).
  • Where there are a particularly small number of circuits per room. Because one dimmer unit controls one circuit (unlike many systems where one dimmer module controls a fixed number of circuits, often 4 or 6), this is a cost effective solution for simpler room schemes.
  • At the other end of the scale, where there are a particularly large number of circuits per room. One Rako controller will ‘talk to’ up to 15 different circuits in any one room. This is beyond the capability of many mid to low range control systems, unless you double or triple up the fixed modules (ie; install multiples of 4 or 6).
  • Where replicating lighting patterns for security reasons is important. Rako allows you to ‘record’ your natural patterns of light and replay it whilst you are away. So instead of having plugs on timers exhibiting a predictable pattern of lighting, the Rako system will replicate you being in the kitchen particularly early one evening, moving in to the lounge, taking a loo break, etc etc.
  • Where you wish to integrate lighting control in to wider house control, without investing in a whole house control system. The Rako system will interface with things such as blind control, electric gates (so when the gates open the lights come on down the drive and in the hall), security (so when a window is opened all of the ground floor lights will come on), etc etc. Usually, if the question is ‘can it do this’ the answer is yes
  • Where simplicity of installation and programming is key. We have for example installed this for clients with houses abroad, with electricians who speak no English. They were quickly able to understand the wiring, and we were able to help the client fine tune the programming by talking him through it on the ‘phone.

So how does it work?
In essence, each controller has a radio frequency transmitter, and each dimmer or switch unit has a receiver. Each lighting circuit has a dimmer or switch unit wired in to it, in line. There are different types of dimmer or switch unit depending on what type of light source you are controlling (eg; halogen, fluorescent or LED), and the wattage per circuit. When the system is programmed you tell each controller which house and which room it is controlling, and each receiving unit which room and circuit it is on. Because it is an RF system you do not have to wire back to the switch as you do with a conventional wiring scheme. All of the other clever things it does are done by the accessory devices and the software programming.

what if my granny comes to stay and doesn’t know how to turn the light on?

A lot of clients have an initial concern around ‘what if my granny comes to stay and doesn’t know how to turn the light on?’. We always recommend putting a wall controller where you would expect to find a light switch, by a rooms’ entrance. The controllers look like sleek switches, and can come in a wide range of finishes. Remote controls are also available.
