LED stands for light emitting diode. LED's are not new, they are the tiny red or green lights on the front of your stereo that tells you that the power is on. Some consoles have quite a few of them to show the state of preparation of the equipment. However, there is a new wave of interest in LED lighting by manufacturers. There is talk of LED's being the future of lighting. In fact, there always has been these rumours about LED's, but nothing ever seemed to come of it.
This renewed interest in LED lighting started in 2004 when vehicle manufacturers took another look at using LED lighting in car headlamps. In 2008, Lexus produced the first ever car, the Lexus 600, with LED headlamps. These cars were exported all over the world except for North America. However, the 600's headlamps were or are not true LED headlamps, the main beam is produced by filament bulbs.
The first true LED headlamps were fitted to the Audi V10 R8 sports car also in 2008 and the first American automobile was the Cadillac Esplanade Platinum in 2009. However, there is an inherent problem with high power LED lights, the back of the diode produces a lot of heat. In fact, a group of high power LED's produces sufficient heat to damage itself and melt the headlamp casing.
There are ways around this using heat sinks and cooling fans, but these solutions are not perfect, so technicians and scientists are still looking for ways to solve this problem. On the other hand, the front of the LED lights produces almost no heat at all, so if there is vapour in the headlamp unit and the ambient temperature is below freezing point, then ice crystals will form on the LED's distorting and dampening the rays of light.
Nevertheless, scientists are sure that these teething problems will be surmounted and that LED lights will one day be the most economical type of lights to use. In fact, it is already very inexpensive to use and the LED lighting units themselves last a long time. It is just the issue of overheating.
Other than their use in car headlamps, LED lighting units can be seen in flashlights and in other parts of cars. Manufacturers are using LED lights more and more often in brake lights, flashing indicator lights and hazard warning lights, because there is no problem at all with these fairly low powered LED lights.
LED lights used to be either green or red, but now it is available in more colours. White and blue are common. The coloured lights that you see under some cars are another example of LED lighting. They serve the useful purpose of making the car of motorbike more highly visible. All right, that may not be why they were fitted, but nonetheless they increase the vehicles' visibility.
Many more uses will be found for LED lights over the coming years. You will notice incandescent bulbs and even fluorescent tube lighting being phased out in favour of LED lights as the problems are surmounted, because LED lights is still in its infancy.
There is no doubt that lighting has the biggest influence on atmosphere and. Subtle lighting in a bedroom or at an cozy dinner creates a romantic ambiance; bright, purposeful lighting in the office or kitchen shows that you mean business; dimmed lighting in the living room makes for a relaxing atmosphere in which to watch a film or read a book.
Soft, back lighting behind flowers or a waterfall leads to a magical atmosphere, whereas severe floodlights turned on by a motion sensor would freeze most intruders in their tracks.
Getting the lighting wrong can have a seriously adverse effect on any room or occasion. Imagine a romantic dinner for two by candlelight and then imagine it by a naked 100 watt bulb hanging from the ceiling or a fluorescent tube.
It is said that the average household can save at least twenty-five percent on its electricity bills by using lighting more effectively and therefore more efficiently. More importantly, you could save more than sixty percent, if you swap from the normal incandescent light bulbs to high-output compact fluorescent lights. Sixty percent is a massive saving for you, your country and your planet.
Here are some of the means that you can obtain savings on the electricity you currently use up on lighting.
Make the addition of dimmers wherever you use lighting. You can insert a touch lamp dimmer into the wiring of any lamp, so that when you touch it, it cycles from low, to medium, to high, to off. You will be amazed how often you will dim the light once you are able to, especially in the case of desk or table lamps and standard floor lamps.
In a similar vein is the touch switch that you can utilize to control lighting that traditionally hangs from the ceiling. You will be able to dim the lights in any room and on the patio or deck too.
Photosensitive devices turn whatever they regulate off or on when the sun comes up. This is useful if you have motion-activated anti-intruder lighting. There is absolutely no need for it in the daytime, but you do not want to have to remember to switch it off in the mornings and reactivate it every night either.
Another use could be to turn the pond fountain off when it gets dark. All of these photosensitive switches can have over-ride switches too. These photosensitive switches will practically half the cost of running the devices to which they are attached.
It is very easy to make fairly substantial savings if you put your mind to it. Just rearranging your furniture to take maximum advantage of natural light can help a lot too. Sitting near a window or in the garden to read the newspaper is far better than having to switch the kitchen light on to read it in there.
In the evening it is better to turn off all the main lights in the living room if you are watching television or reading a book and place one standard floor lamp just to one side behind you. It is sufficient to read by or to save your eyes from the strain of watching TV in the dark.
Most people who like to work in their garden pay a lot of attention to its state and how it looks. They not only focus on the gardening aspect i.e. taking care of the plants, trees and bushes but also the inanimate aspect i.e. beautification, utility equipment and, most importantly, lighting. If you are an individual who has just realized that his garden needs the right kind of garden lights and are now looking for lighting options to achieve this then you should consider the solar garden light. The reason why you should consider a garden lighting system based on solar energy for your garden is that they provide many benefits. Consider the following.
1. The most obvious benefit of using a solar garden light system is that it would allow you to save a lot of money because your lights would get their energy from the sun and not the local power grid.
2. Using a garden light system that is based on solar energy would also allow you to do your bit for the environment in times when the world is slowly giving in to pollution and global warming.
3. A logistical benefit of using a lighting system based on solar energy in your garden is that the system would be completely free of wires.
As you can see from the benefits listed above, a garden lighting system based on solar power would bring you benefits in terms of your pocket, your conscience and even your comfort.
If the above mentioned benefits have helped you make up your mind that you want a solar lighting system installed in your garden then you would also have to learn a little bit about all the different types of solar garden light that are available in the market.

3. Lamp posts:
Every garden is going to need to be lit, over and above the ornamental highlighting and pathway lights. This is where the solar lamp posts come into the picture. These are the brightest solar garden light you will find in the market. It is also worth noting that these are usually tall so as to allow them to light a larger area.
