Outdoor LED Lighting, the best of both worlds for energy efficient area illumination

Outdoor LED LightingSolar power as a source of electricity for powering outdoor lights has met its ideal technological match in LED (light emitting diode) components for outdoor LED lighting.
Let’s start by discussing solar power as a reliable source of energy for outdoor lighting. The benefits of using the power of the sun to gather energy which is then converted to electrical power for outdoor lighting, is undisputed.

Managers of public spaces, large estates, sporting venues and harbors, railway stations are installing solar outdoor lighting almost as a matter of course. Opening trenches, introducing meters and laying cables makes no sense when you can install a light wherever you want with its own energy producing “factory”, namely the photovoltaic cells mounted on the light itself. The solar energy is converted to usable electrical energy and stored in batteries for use whenever the light has been programmed to switch on. The bottom line is that the battery in such a device can be used to power any kind of bulb, just as an ordinary battery does.

Outdoor LED lighting is perfectly suited for solar applications

In line with solar power’s low-maintenance and eco-friendly characteristics, LEDs produce more light per watt than incandescent bulbs, making them ideal in battery powered or energy-saving devices. Another positive factor keeping prices down is that LEDs can emit any color light required without the use of filters such as traditional forms of lighting require. This substantially reduces initial costs. In addition, the solid package of the LED can be designed to focus its light. In contrast, fluorescent and incandescent sources often require an external reflector to collect light and direct it suitably.

Outdoor solar lighting is subject to frequent on-off cycling

When the lighting system is gathering solar power during the day, the light itself is programmed to be switched off. When dusk comes it switches on. Again, LEDs are perfectly adapted to the situation. Unlike fluorescent lights that burn out quickly when subjected to frequent cycles, LEDs can take the pace.

Another factor that makes LEDs such a good match when it comes to outdoor solar lighting is that LEDs, being solid state components, are incredibly resilient and tough. Even a hard blow to an outdoor LED lighting unit will cause no damage. This is obviously in marked contrast to fluorescent and incandescent bulbs, which are as delicate as eggshells.

LEDs also have long lives; a desirable characteristic is devices that are meant to be low maintenance devices, as solar powered outdoor lights are. An LED typically has 35,000 to 50,000 hours of useful life, whereas fluorescent tubes last about 30,000 hours and incandescent bulbs just 1,000 to 2000 hours. Also, LEDs tend to fail by dimming over time, rather than suddenly burning out. LEDs are eco-friendly in the long term, just like solar power. They do not contain mercury, unlike compact fluorescent lamps. More on LEDs

Outdoor Solar Lighting, the natural and economical alternative to grid power

Outdoor Solar LightingThere is much talk in the media about outdoor solar lighting and solar power as an obvious alternative to the commonly mass-produced electricity sources involving the burning of fossil fuels and nuclear fission.

Because solar panels are still a rarity, lots of people think that solar power has not come of age. In fact it has come of age, but not yet as a commonly used source of electricity for applications inside buildings. Instead the great technological strides have been made in solar lighting technology thanks to the cost-cutting drives by managers of large business complexes and public spaces.

Solar power outdoor lights can be found in parks, hotel grounds, hospitals, at airports, harbors and train stations. And, of course, solar powered street lights, traffic lights and parking lights are operating quietly and efficiently not very far from where you now are.

A pioneer industry in the field of outdoor solar lighting was the maritime industry

Presumably because sea-going vessels operate so close to the elements – the wind and the sun – sailors and skippers were among the first to ask why the exposure of boats to the elements could not be put to good use. The solar manufacturing industry was quick to meet the need. Today every yacht, ship or tender has a range of solar power lights for every possible use.

Whether it is emergency lighting, night lighting, danger lighting, SOS lighting, it is available to the maritime industry. Even buoys in harbors are solar powered. In its quiet and unobtrusive way, solar lighting is taking over from expensive and harmful grid electricity in dozens of ways. For those who are keen to know that they do not leave a dirty carbon footprint behind when lighting outdoor areas, solar lighting is the answer.

Nothing is burned and nothing is wasted where outdoor solar lighting is used

Apart from their attractive “green” aspect, solar outdoor lighting systems provide great convenience, efficiency and reliability. Obviously a main solar benefit is that no power bill arrives at the end of each month, plus each solar light has its own little “power plant” in the form of photovoltaic cells, as well as the system for converting solar power to electricity, on the light itself. This means no opening of trenches, no power generation stations, no cables, no meters, no substations, no switches and no transformers.

The initial costs of outdoor solar lighting systems are limited to the self-contained energy collection and distribution system and the attachment of the unit to the location where it is required to operate. In other words, you place it in the sun where it can collect energy and where it can distribute light at night.

Because each and every solar electric light operates independently, each one has its own control system so it can be programmed to turn off and on as needed. It can also be controlled by a light sensor for dusk to dawn operation. When compared to the traditional systems’s cost for cable, trenching, metering equipment and construction – plus monthly electric bills ad infinitum – the advantages of solar lights are immediate and dramatic

Solar Outdoor Lighting, all the benefits of grid power with none of the downside

Solar Outdoor LightingMention solar outdoor lighting and most people think of the arrays of photovoltaic cells mounted on the roofs of homes and other structures, solar panels that produce electrical energy for heating water and running lights and appliances inside the buildings.

It is a little-known fact that the main strides in solar technology over the past few years have been made in the area of solar lighting applications. Because most such applications are in public spaces such as streets, parking lots, parks, harbors, airports, hospital complexes and college campuses, mainly managers and developers are in the know about this incredible form of lighting.

With the huge increases in the costs of grid power and fossil fuels, the demand for these sun-powered outdoor lights is increasing and even spreading to the hotel and resort market. Once visitors see these solar lights in hotel gardens, you can be sure the trend will spread to domestic outdoor lighting.

Solar outdoor lighting is a robust form of low maintenance, low-cost illumination powered entirely by the sun

Each light has its own sun factory, a set of photovoltaic cells mounted on the light itself and adequate to keep the light burning at night. The exact times the light draws upon the saved solar energy, which has been converted to solar energy by an inversion mechanism and stored in batteries, can be determined on a computerized panel applying to the light. You are probably asking what the catch is. The answer is that there is no catch unless you include the doubt that still hangs round in the back of peoples minds when they think of solar power. A cursory examination of the facts, however, proves that there are only benefits accruing to solar outdoor lighting, with zero downside.

  • First, no trenching, metering or wiring is required for the installation of solar outdoor lighting systems. This in itself is a massive cost saving. The other point about this is that each light operates independently from the others. In the unlikely event that there was a problem with one light, the rest would carry on operating. In addition, this means that the location of the light is not limited to where power lines run. A solar light can operate in the middle of a parking lot, in the middle or a harbor or on top of a mountain. The sky is the limit.
  • Second, installation involves merely attaching the solar light to the roof, wall or other surface.
  • Third, no maintenance is required. The solar light operates indefinitely without attention. Fourth, solar energy from the sun is free, so no electricity bills are in the mail.
  • Fifth, solar energy gets collected even on cloudy days, even if it is raining, so electricity is continually being gathered.
  • Sixth, blackouts become a thing of past with solar outdoor lighting, guaranteeing illumination for convenience and security.
  • Seventh, and finally, the energy powering a solar outdoor light is completely clean. Using solar power means leaving no ecological footprint, and that is good news in an eco- conscious world.

Outdoor Lighting Systems, clean options for the 21st century

Outdoor Lighting SystemsAs the price of fossil fuel rises there is much speculation everywhere in the world about how solar outdoor lighting systems is the obvious alternative to expensive and destructive fuels such as coal and oil.

Few people are aware though that many property developers and city managers have taken the step and installed commercial solar lights for parking lot lighting and solar street lighting systems in place of regular street lights. Harbor management in nearly every country is familiar with solar lighting.

The maritime industry, presumably because of its close association with nature in the form of the winds and the oceans, has adapted to the necessity for cheap and reliable lighting.

Marine lights are on board vessels, on the docks and in the harbors themselves, where they are used as buoy lights. These solar outdoor lighting systems are highly developed and readily available. They can be at specialist stores on the internet. It is intriguing to see how advanced these solar lights are these days.

Manufacturers and suppliers of professional solar lights are often asked just how dependable solar power lighting is. The answer they give is that this cheap and clean form of lighting is very dependable indeed. They quickly dispel the notion that solar energy cannot be collected in cloudy weather. The rule of thumb is that if you can still see reasonably well, even if it is overcast and raining, then there is enough light to collect and store energy.

The storage aspect of solar lighting is important

It ensures that solar power will be available for at least five days even if no more solar power is collected which, as explained, is unlikely to occur. In addition, the best solar outdoor lighting systems are custom made and therefore the components are perfectly adapted for the job, making it virtually maintenance-free. In any event, the reputable solar lighting suppliers offer generous warranties on their products.

A point that manufacturers and suppliers of solar lights also bring to the attention of those who are investigating the viability of solar light power is that each light is an energy factory on its own. In the unlikely event that one were to fail, the others would keep on going as before, making solar lighting an incredibly reliable form of lighting. Each solar outdoor light has its own power plant (the solar cells and batteries) so the light’s operation does not rely on any outside factor, such as the electricity grid. In addition, each solar electric light operates autonomously. Each light is programmed through its own control system to turn on and off as required.

The medium to long term benefits of solar outdoor lighting systems are huge

Initial installation costs are incurred for the self-contained energy collection and storage system (photovoltaic cells, solar charger and batteries) but after that the energy itself is free from the sun. When compared to the cost of installing grid-fed systems and the electricity bills that result from its usage, outdoor solar lighting wins hands down. It is no wonder that estate, sports and hotel facility managers are buying into outdoor solar systems.

Solar Traffic Signs, LED technolgy for road safety

Solar Traffic SignsSolar traffic signs can undertake a vital function in a modern, advanced traffic management system. These signs are strongly illuminated and therefore easy to read, making them much more suitable for their purpose of ensuring the attention of road users. In addition, of course, they have the considerable benefit of helping to conserve energy because of their environmentally conscious solar technology.

An analysis of the need for solar traffic signs and their advantages will make it quite apparent why they have proved to be so suitable for traffic management applications such as the advanced warning of hazards.

The situation with regards to conventional sources of fuel for electricity has been deteriorating rapidly in recent years and, as our reserves of fossil fuels have rapidly been dwindling, so scientists and engineers have been seeking viable alternatives. Solar energy represents the cutting edge of this research and is now being employed in numerous ways in connection with traffic management. For example, solar street lights, solar road studs and solar traffic lights are now routinely being used in many parts of the world.

So, why solar traffic signs

Well, the first of a whole host of benefits to be gained from using solar signs is that they are absolutely simple to install at any location. With no cables to run or generators to transport, solar signs can be quickly, easily transported to the place you want the sign and then erected within minutes. This means that unexpected traffic problems which necessitate some kind of warning or advice sign for road users can be up and running very quickly – often needing only one person to undertake the installation.

Solar road signs operate by utilizing Light Emitting Diodes (LEDs), which are far brighter than conventional light bulbs – meaning that visibility is much clearer for road users, therefore making the roads safer. These extra bright LEDs also last for a considerable length of time, consuming remarkably little energy in comparison with their conventional counterparts.

Solar outdoor lighting systems are designed to store the energy produced by the solar panel in a battery – itself charged by means of a solar charger – which can keep working for up to two years.

Solar traffic signs can function efficiently during the night as well as during daylight hours

They can be controlled by a timer, or by a remote control device, or they can be programmed to flash to attract the attention of motorists or other road users to give them necessary information. It is now quite possible to program a sign to present different messages at various times of the day, to cater for different road conditions. Additionally, because of the developments in solar technology, there is no need to worry about overcast or cloudy days – the signs nowadays will just keep on working.

Similarly, despite their small size and ease of transportation, they are able to withstand buffeting from strong winds, whilst continuing to function. The effectiveness of the solar technology and the lack of cables, etc also means that, once in position, solar road signs are refreshingly self-sufficient and require very little in the way of maintenance.

There are countless applications for solar traffic signs – around schools, pedestrian crossings, working areas, accident ‘black spots’, emergency road or lane closures or traffic diversions and many, many more. This is a market which, undoubtedly, will continue to expand in the foreseeable future. More info
