Holiday Lighting
Strands of LED lights are quickly replacing traditional strands of lights in holiday decorating. The LED strands can be strung together like traditional strands to decorate the outdoor of your home, Christmas tree or other areas that you decorate during the holidays.
Traditional strings of holiday lights have a very short life. Most people need to replace a string or two each year. Anyone who decorates a house year after year knows the frustration of working all day to decorate and then having a strand not light up when it all gets plugged in.
LED lights can eliminate this frustration. The strands of LED holiday lights can last up to 100,000 hours so the filaments of a bulb burning out is no a problem. They are very difficult to break even if stepped on.
These strands also cost less to operate because they use around 90% less electricity than traditional strands of holiday lights. The strands of LED lights are more expensive than the traditional strands, but when you factor in the savings in electricity and replacements over the years they are the better financial deal.
Because of the many benefits that LED lighting provides, their use in homes will increase greatly as the amount of available products increases. They save consumers money both in replacement fees and electricity. They are environmentally friendly because of their low energy consumption. Additionally, they save consumers from spending the time to replace lights, some of which are often difficult to reach. As consumers become aware of these factors, traditional lighting will be replaced with LED lighting in homes.
LED and Business Office Use
While the adoption of LED lights as the standard for residential lighting is 5-15 years off in the future, public buildings like government offices, shopping malls and office buildings are beginning to take advantage of the economy and flexibility of LED lighting. Theaters, clubs and upscale restaurants are leading the way with digitally enhanced ‘video walls’ that change color with music or display projected images and television broadcasts.
Even sedate government offices benefit from LED light technology though. While the initial cost of installing LED lighting is about double that of traditional light sources, in the long run lighting with LED can save millions of dollars in maintenance and energy costs. Traditional fluorescent or incandescent bulbs would need to be replaced 8-20 times during the life of a single LED light. In addition, LED lights offer the same degree of illumination as incandescent or fluorescent lights at about 10% the energy cost. It’s been estimated that replacing only the EXIT lights in government buildings across the United States with LED lights would save the country millions of dollars a year.
With all that going for it, why will it take fifteen years or more for LED lights to be in popular use for illuminating residences? Mostly, say lighting experts, it’s a matter of making the conversion easy for regular people. All it will take is for someone to invent LED lights that screw into regular light fixtures, and our world of lighting will never be the same again.
LED’s and Mental Health
Another product in development is a window curtain with ‘smart LED lights’ that respond to the light from outdoors. As the light outside fades, the LED lights in the curtains brighten, giving the effect of lengthening the daylight by continuing light from the same source and direction. Psychiatrists are already studying the LED light curtains as a possible way to help alleviate conditions like Seasonal Affective Disorder which plunges a large segment of the population into depression during the winter months.
Indoor Lighting
LED lights can be used in any indoor home lighting situation that traditional lights can be used in. Here are some of the products that use LED lighting indoors.
Desk/table/floor lamps – Using desk, table or floor lamps that use LED light has many advantages. These types of lamps are frequently knocked over, breaking the filament in traditional lights. When the filament breaks, the light stops working even if the light bulb has not shattered. Because there are no filaments in LED lights to break, they do not stop working when knocked over. LED lights are encased in strong plastic and rarely do they break or shatter.
Also, because there is no burning filament in LED lights, they burn much cooler than traditional lights. This is especially ideal for desk, table and floor lamps because the risk of a burn is greatly decreased. Using the LED lights in children’s rooms for their bedside light or table top light is a good way to keep curious little fingers from getting burned.
Overhead lighting – The products for overhead lighting such as ceiling lights, ceiling fans, track lighting and recessed lighting seem to be more difficult to find than LED lamps. As consumers continue to learn the advantages of LED lights, these products will increase on the market place.
LED lighting’s long life is particularly convenient for overhead lighting fixtures. The frequency in which the lights need to be changed is much less than in traditional lights. That means less pulling out the ladder or the step stool to change the bulbs.
Night lights – Night lights made with LED lights are longer lasting than traditional night lights. This makes them a less expensive option. They can be purchased with light sensors that automatically turn them on when it becomes dark.
LED candle lights – LED candle lights are an alternative to wax burning candles. Because they don’t have a flame or hot dripping wax, they are much safer than traditional candles. They are ideal on table tops at a wedding reception, in a dorm room where burning candles are not allowed, or in outdoor situations where a flame may be easy blown out by the wind.
LED Lighting Uses Growing in State and County Applications
Other traffic signaling and messaging systems that make use of LED lights are coming into more popular use as well. Arrow boards on trailers can warn drivers of construction and direct them around obstructions. Powered by solar panels, or by battery, arrow boards reduce the need for extra safety officers at construction sites and are far more visible than standard reflective signs.
Many cities and counties have started using speed monitoring signs to encourage drivers to slow down. LED lights powered by digital electronics display the speed limit and the speed of the approaching motorists at dangerous intersections, school crossings and other places where the speed changes. Studies have shown that a speed advisory system makes a significant difference in reducing accidents at dangerous curves by making drivers aware of their own speed in reference to the speed limit.
State highway systems are also using message boards with LED lights to deliver traffic status updates, important news and safety messages along the highways. The digitally controlled messages can be programmed to scroll or flash to increase their usefulness, and can inform drivers of detours and alternate routes, speed limits, seat belt reminders – with several programmable messages available at all times.
The traffic signaling industry is one of the two areas where LED lights have penetrated the market most deeply, according to a spokesman for the Department of Energy. As the LED light industry overcomes the few remaining challenges expect to see LED lights move out of the area of utility and novelty and take their place as the major form of light in the world of tomorrow.
LED Lights Stop Traffic – And A Whole Lot More
The newest advances in the technology behind LED lights are literally stopping traffic on the streets of major cities throughout the world. The lower energy use, longer life and greater ease of integration with digital controls are prompting cities all over the globe to replace their current traffic signaling devices with LED lights. In fact, according to Arpad Bergh, the president of the Optoelectronics Industry Development Association, traffic signaling and other messaging applications are two areas where LED lights have made the most inroads into popular use.
Writing in 2003, just two years ago, Bergh used an example of the traffic lights in Taipei to illustrate a point. Those traffic lights, which feature an animated ‘green man’ walking across the intersection during the pedestrian phase of traffic, are now widely used in cities in Europe and the United States as well. The pedestrian crossing lights use LED lights to tackle one of the smaller irksome problems that faced traffic control engineers – warning pedestrians that the light was about to change. The solution – LED lights create the animated man who walks, then hurries, then finally runs as the time comes close for the traffic light to change.
Other manufacturers have chosen different approaches using LED lights to solve the same problem. Some feature a digital countdown of seconds until the light changes, or a combination of animation and countdown clock powered by LED lights. Pedestrian crossings powered by LED lights are generally safer than those that use standard crossing signals that offer no warning that the lights are about to change.
But pedestrian crossings are just one of the areas that LED lights offer advantages over more traditional traffic lights and signaling devices. LED lights are brighter, cheaper, more energy efficient and more flexible than the incandescent halogen bulbs used in traditional traffic signals.
