RAKO TO SOLVE YOUR LIGHTING CONTROL PROBLEMS

Rako is a British company that was launched in April 2002 by five guys who came together with a long history of experience in the commercial lighting control industry. Their ambition was to provide a viable solution for lighting controls in the domestic market, with a strong focus on providing excellent customer service, technical support and product training.

Designed and manufactured in the UK. With a wealth of experience in lighting controls, Rako offers an unparalleled range of products backed by a project planning and support service that is second to none.

What Rako offers is a push-button mood lighting control system that allows users to recall a lighting scene by pressing one button rather than adjusting several rotary knob type dimmers. Mood lighting systems, recalling a pre-programmed scene at the touch of a button, offer sophistication, ease of use and energy saving, controlling all light sources and curtains and blinds, including dimming of LEDs. With seamless integration to home cinema, multi-room audio, security systems and with ‘holiday mode’ functions the Smart Home dream becomes a reality.

Retrofittable wireless modules allow systems to be installed with the minimum of fuss and expanded later while CAT5 wired options cater for the largest of projects. With wireless/wired bridging even combined systems are possible. With control options from keypads, remotes, tablets or Smartphone Apps, Rako provides the user with ultimate flexibility. Having extended its range by launching a wired system, Rako now enables the installation of wired, wireless or combined lighting control systems. Users can choose between added functionality of wired, with more scenes and LED tellback panels, the convenience of wireless, or a combination of both to form a seamless hybrid system. And with both wireless and wired modular keypads providing the option to laser engrave individual buttons, users can customise their own keypads.

 

Put simply, Rako offers everything that a Smart Home needs from lighting control but with an unprecedented ease of installation.

Some key benefits:-

Comfort

Mood lighting systems offer the user the ability to recall a scene, or mood of lighting at the touch of a button whilst controlling multiple circuits and lamp types. Circuits split to define zones and highlight room features are programmed to suit the different uses of a space with scene changes incorporating fade times to give subtle lighting transitions.

Energy Saving

Dimming lamps has always saved energy and in an increasingly energy conscious world this is ever more important. Recent technology has led to a rapid change in the lamp types available for use in the modern home, but more energy efficient light sources such as LEDs and fluorescent lamps require more sophisticated dimming solutions than conventional tungsten.

As a result dimming controls need to be more advanced and well matched to the chosen lamps. Rako is at the forefront of providing smooth, efficient solutions for the most recent fittings and publishes application sheets and compatibility guides to help designers.

Curtain and blind control

As well as their privacy functions, curtains and blinds control natural light making window treatments a logical partner for lighting control. Combined panels with lighting functions lessens wall clutter and control is available from the same remotes, Smartphone Apps and interfaces as the lighting system.

 

Security

Automatic lighting and curtains with timed or ‘holiday mode’ functions provide the impression of occupation. With static curtains and unlit homes being one of the biggest tell-tales to would-be intruders this provides invaluable security. Linking fire and burglar systems to lighting gives the comfort that if the worst happens home-owners are not left in the dark with either a fire or an unwelcome guest.

Integration

Rako’s System Bridges offer Integrators all the options needed to incorporate a Rako system into an overall control package. From Smartphone Apps to RS232 and IP input, Rako supports all the necessary protocols allowing installers to provide the end user with clear, uncluttered and intuitive control.

Ease of Installation

The barrier to installation of control systems is often not the product cost, but that of installation and re-decoration. For ground-up builds Rako has the wired, Cat5 networked system, but for retro-fits and hassle free installs Rako’s wireless option provides the ideal solution. The ability to be able to combine both wired and wireless options gives the ultimate in flexibility when planning a system.

For years the tungsten lamp in its various forms has been the mainstay of domestic lighting and with the filament providing electrical resistance the lamps have been self-regulating and could work directly from a constant voltage supply, be that the mains or 12V from a transformer.
The rapid rise in popularity of LED lighting is the single biggest upheaval in the lighting industry since the introduction of the electric lamp and the use of LED’s has pretty much become the norm within lighting design now. This creates opportunities and difficulties alike. As with all revolutions things can get messy and confused before order is resumed. Unfortunately with the benefits of increased efficiency that LEDs bring also comes confusion amongst installers, end users and suppliers alike. For a manufacturer like Rako Controls the challenge is to keep abreast with the changes, keep customers informed and provide solutions for the myriad of products available.

We are continually developing new products to keep on top of this fast moving sector offering smooth flicker free dimming control. This is often down to the quality of the LED lamp or driver and therefore at Rako we have tested and publish results of over 100 lamps and drivers giving the installer and end user a choice of lamps.

RAK-4_01An LED needs some form of regulation to stop it drawing an infinite current when connected to a constant voltage. Fittings with no regulation are therefore known as ‘Constant Current’ and need some external device, or driver to control the current. Dimmable drivers may be controlled by a 0-10V signal or dimmed with more conventional dimmers. In an effort to make lamps retro- fittable GU10 style lamps are now very common with a driver in-built into every lamp. The performance of these lamps varies considerably and many control manufacturers go to long lengths to test and issue compatibility charts. The two most common dimming methods are mains dimmers and 0-10V signals. If mains dimmer is used then the lamps tend to operate better with transistor dimmers than with triac dimmers, for much the same reasons as for the compact fluorescent lamps. 0-10V dimming normally gives good performance, but at the cost of extra wiring requirements in the installation. One truism though is that generally these GU10 lamps, and the remote mains dimmable drivers for constant current fittings perform much better with the more sophisticated trailing edge dimmers such as Rako’s RMT500 and RAK4-T.

Rako MH03LED tape provides a different control issue, with the power of the fitting being unknown (because it’s cut to length) a different regulation technique is needed and this is achieved in a twofold manner. The final current regulation is managed with tiny resistors mounted on the tape alongside the LEDs allowing the whole strip to be fed from a ‘Constant Voltage’ 12 or 24V d.c. power supply. Control of LED tape usually involves fitting a dimmer device between the power supply and the tape such as Rako’s RLED50-1DCV module.

Typically, high-wattage LEDs are designed to be used at a specific maximum current such as 350mA, 700mA or similar. Where there are two or more LED lamps connected to a ballast, it is common to connect these LEDs in series – which is unlike any other lamp in common use. The number of LED lamps that can be series-connected to a single ballast depends on the maximum power output and voltage that the ballast can output. There are so many possible combinations of current, voltage and number of LEDs that the selection of a ballast can become quite bewildering.

By developing dimmable energy-efficient light sources, manufacturers will ensure that people can continue to enjoy subtle mood lighting within their homes. While the introduction of energy- efficient halogen lamps is providing a smooth transition towards this lower energy future, fluorescent and LED lighting can provide even greater energy savings, although the dimming of these lamps is currently less simple. Compact fluorescent lamps do have a price/performance advantage, but it is LED technology that is attracting the most attention as it offers easier dimming than fluorescents.

The world of LED lighting is changing fast and picking a route through the somewhat baffling range of products and confusing terminology is hard. Make the effort though, it is the lighting of the future.
