LED CEILING LIGHTS: THEY WILL REDEFINE YOUR LIVING ROOM

LED lighting is one of today’s most efficient and rapidly-developing technologies. They last longer, offer better light quality and are more durable. Like any other diodes, they consist of a semiconductor material doped with certain impurities to create a p-n junction. Current flows smoothly from the anode (p-side) to the cathode (n-side) not in the opposite direction. When an electron collides with a hole, it automatically falls into the lower energy level and generates photon energy.

The benefits

LED ceiling lights exist in different sizes and shapes, with excellent fittings available for any room. Whether your home is stately or terraced, you can utilize these lamps to positive effect. The type of illumination you’ll get not only looks attractive, but it’s economical. They last much longer than traditional bulbs and consumes up to 90 percent less energy. The possibilities of LED ceiling lights are endless. It doesn’t matter how small or big your house is you’ll always find something that perfectly matches your needs.

Why You Should Consider Them

LED ceiling lights are ideally suitable for applications which are subject to recurrent on-off cycling, unlike traditional lamps that quickly burn out when cycled frequently.
• They can easily be turned down or dimmed
• Installation is quick and very simple. A common indicator will attain full brightness in microseconds.
• They don’t contain mercury, unlike fluorescent lamps
• They are relatively small in size and are easily fixed onto printed circuit boards.
• Being solid state devices, they are difficult to get damaged with external shock, unlike incandescent and fluorescent bulbs which are fragile.

Light emitting diodes are the latest and most sensational technological developments in the lighting industry. They are small, compact light bulbs which are exceptionally energy efficient and durable.

Amazingly Efficient and Energy-Saving

Additionally, LED lighting offers several other advantages, including longer life (60,000 hours), reduced maintenance cost, lower energy consumption, and increased safety. Currently, they are being used for numerous applications- automotive, residential lighting, broadcasting, industrial automation, aerospace, entertainment, and electronic instrumentation.

Also, they are extremely energy efficient and use only a small fraction of the energy consumed by fluorescent lamps; there’s dramatic reduction in power costs. Since they don’t incorporate delicate components like glass and filaments, they’re able to withstand vibrations, shock, and extreme temperature.

Safety and Color

LED ceiling lights produce virtually no heat hence they can be left on for several hours without harmful effect if touched. They generate 3.4 BTU’s/Hour and reduce the potential risks of burns and fires.Moreover, they are fabricated with non-toxic materials, unlike conventional lighting options that use mercury which may cause danger to the environment. Also, they are recyclable and earth friendly.

LED ceiling lights are available in a wide range of colors- red, blue, amber, and green. Since incandescent bulbs use filters to generate colors, they’re extremely inefficient. Note that they can be combined to create millions of colors that can bring more elegance to your kitchen, bedroom, or even bathroom.

Emergence of reliable and Efficient LED light Bulbs

Most of the people still believe that incandescent and CFLs are better options than LED lights because they are cheap and attractive. However, with the passage of time, both incandescent and CFLs have phased out because they were unable to produce the desired quality of light. In fact, they failed to show their caliber on broader level, which has allowed LED light bulbs to come at the forefront. LEDs are not only energy efficient, but they also last longer.

One of the major factors behind the setback...

One of the major factors behind the setback of incandescent and CFLs is that they contain hazardous elements that are hard to dispose. CFL bulbs have mercury in them, which is quite dangerous for both residential and commercial use. In fact, these can’t deliver directional lighting that is required for reading or cooking.

RAKO WIRED VS WIRELESS SYSTEMS

Introduction

Rako is one the leading lighting control systems which performance admirably against the competition Lutron and Control 4 but does benefit by being of lower cost and it is easier to install. This makes it an ideal choice for high end residential and commercial properties.
One of the key benefits of Rako is the wireless solution which makes it a first choice for retrofits to existing properties where the lighting wiring is in place but there is no automation.
The key element of lighting control is to be able to select lighting scenes for a space which are set at the push of a button which will dim all the different lighting circuits to a prescribed level in the room. Rako allows you to have between 2 and 7 lighting scenes dependent on the selection of the control panel. For example a RCM-100 will allow 7 scenes to be programmed and a RCM-070 4 scenes.

Typically the scenes can light different areas of the space and allow for relaxation or for working by setting the light levels to the appropriate setting.

The Wireless Dimmers.

The RMT500 wireless dimmer is a trailing edge dimmer unit which has compact proportions and accordingly can be slipped up into the ceiling void through down-lighter holes. This means the converting a conventionally wired property to lighting control is straightforward and the existing wiring can normally be used. As the control panels are wireless these can then be positioned in place of the existing light switches or alternatively placed elsewhere in the room as no switch wiring is needed. The RMT500 is a very versatile dimmer which works very well on good quality LEDs anb depending on the back load of the LEDs can operate up to 500 watts of load. For larger loads the RMT1200 is a preferred choice as this can handle loads up to 1200w. There are leading edge dimmers available as well which are often better for incandescent or dimmable fluorescent loads. More details on the dimmer please take a look here RMT500.

Benefits if the Wireless System

• Good for retrofits and no switch wires needed
• Lower cost of control panels
• Extra control panels can be easily introduced at a late stage as no wiring needed

Wired Systems

For a wired system the RAK4 dimmers would normally be used, typically the RAK-4T which is a 4 channel trailing edge dimmer. These are normally located in a control room and all the lighting circuits would be run back to this room. The RAK-4T will take 4 channels but these can be linked together with a RAK-LINK to allow up to 8 RAK-4T dimmers to be connected together.

The other element of the wired system is the control panels. With the wired system then the control panels typically the WCM-070 would be daisy chained together with CAT5e cabling. If it is more convenient then a RAK-STAR can be used which means the control panels can be star wired from the control room.
However it is still possible to utilise the wireless control panels with the RAK system. This is done by introducing a RX-Link which allows wireless devices for instance control panels, to be connected into the Rako RAK dimmers.

Benefits of Wired System

• No batteries needed for control panels
• Control panels have back lit buttons for ease of viewing in the dark
• Programming easier where it is desired to control lighting is different rooms from certain control panels
• No limitation on RF signal strength and no distance limitations

Evolution of Lighting Technologies

Incandescent Light Bulbs

Lighting has evolved over the years. Let’s find out how it evolved. As we know Edison invented it to transform our life. By the way, you will be surprised to know that he also developed the first electric meter.

While Edison was working on the whole lighting system, there were many inventors that were putting their efforts to make several advancements in order to improve the filament manufacturing process. As a result, a dramatic change in the technology came in 1904, when European inventors invented tungsten filament. The new tungsten filament bulbs were quite significant and have the ability to last longer. 

The saga continues and 1913 became yet another remarkable year. This is the year, when Irving Langmuir pointed out that placing an inert gas like nitrogen inside the bulb can improve (double) its overall efficiency. By the 1950s, inventors and researchers had only figured out how to convert about 10% of the energy the incandescent bulb used into light. They began focusing on other more innovative lighting solutions.

Emergence of compact fluorescent light (CFL)
 

Furthermore, the oil crisis of 1973 forced lighting engineers to develop an efficient fluorescent bulb. 1976 was yet another significant year in the history of lighting when Edward Hammer of General Electric pointed out how to bend the fluorescent tube into a spiral shape. This was resulted in the development of the first ever compact fluorescent light (CFL). Early CFLs hit the market in the mid-1980s; however, they were bigger in size and somewhat bulky, as a result they didn’t fit well into fixtures.

It must be noted that CFL uses about 75 % less energy than incandescent and last longer say about 10 times longer.






Era of light-emitting diode (or LED)

One of the fastest emerging and developing lighting technologies today is the light-emitting diodes (or LEDs). Initially, they were used in a wide variety of applications including traffic lights, flashlights, etc. Since then, LEDs have evolved, no wonder, today, it is the most efficient lights than any other traditional lights. And the reason is simple - they have many advantages over incandescent light sources, including lower energy consumption, longevity, performance, robustness, compactness and much more.


Facts:

LEDs contain no mercury, and a recent Energy Department study determined that LEDs have a much smaller environmental impact than incandescent bulbs. (source – energy.gov)
The LED was invented by Nick Holonyak Jr. in 1963 while he was working for General Electric. (source - phoenix.gov)

A business, such as a warehouse or large hotel, can save up to 70% of its electricity costs by switching to LED lights with motion sensors...and receive a payback on the capital outlay within two years. (source - http://www.energysavingtrust.org.uk/blog/future-led-lighting-gets-brighter)

Today, LEDs are used in the widest possible applications from aviation lighting, automotive headlamps, advertising, general lighting, to traffic signals.
