Google the term Perovskite or organometal halide perovskites and you’ll find very long  scientific descriptions, and complicated chemical composition models.  Chemistry definitions aside, one of the reasons that Perovskites are exciting, is because in 5 years or perhaps even less, LED Lights based on perovskites could be commercially available.

Why is that exciting?  Well, the main reason is that the process to make these types of LED is far less complicated, and remarkably clean.
Zhi-Kuang Tan, lead author and graduate student at The University Of Cambridge’s Cavendish Laboratory, says in a university press release:

“It’s remarkable that this material can be easily tuned to emit light in a variety of colors, which makes it extremely useful for color displays, lighting and optical communication applications.” “This technology could provide a lot of value to the ever growing flat-panel display industry.”

Phoenix AZ Retrofits Street Lights With LED’s

LED LightingPhoenix, AZ has begun a street light project that involves that conversion of 700 high-pressure sodium (HPS) lights to LEDs. The city is projecting 60% energy savings from the retrofit and plans to convert all 95,000 legacy fixtures in the city by 2020.

Phoenix performed significant field testing to make sure the LED’s would hold up to the extremely hot temperatures in that area. After testing and evaluation, the city along with  Arizona Public Services, chose the GE Evolve LED lights as their standard.

“These LED’s will be installed anywhere a fixture needs to be replaced or where new construction and capital improvements occur,” said Jason Fernandez, principal engineer technician with the Phoenix Street Transportation Department. “Additionally, with the energy and cost savings we experience from each new fixture, we’re putting that money toward our investment for more LED street lights.”

That initial phase will deliver $57,000 annually in energy savings and $41,000 annually in maintenance savings. The city projects 11 years of maintenance-free usage based on 12-hour days and the 50,000-hour expected lifetime.

Ultimately, Phoenix plans to install LED lighting along 4800 miles of roadway by 2020. The project will encompass 95,000 LED fixtures.

New Research Shows LED Lights Help Thwart Seasonal Depression

LED LightingLet’s face it.  We all hate the cold, especially after a winter like the one we just experienced.  The cold makes us lose sunlight and warmth, and if you have ever found yourself refusing to get up during the winter, then you understand that sometimes you just can’t cooperate with life during the winter.

Well, you’re not alone.  In fact, the feelings that you may have during the winter might be hinting towards an issue that is larger than just a simple infection of procrastination.

Seasonal Affective Disorder, also appropriately known as S.A.D. or “winter depression”, is a form of Major Depressive Disorder that is only experienced during the winter.  Those who are afflicted by this disorder experience depressive symptoms such as a dramatic change in weight, an inability to wake up in the morning, and/or a general disinterestedness.

For a while there weren’t many ways to keep this sleeping monster at bay.  In recent LED lighting news, however, there has been research presented in which LED lights have been found to help thwart seasonal affective disorder.

This is mostly due to the human body’s response to sunlight and the lack it that we receive over the winter.  In order to help keep the depression at bay, a daily or even weekly application of LED-based light for about a half an hour has been proven to mitigate S.A.D.

There are a couple of reasons that explain why LED lights are used to reduce seasonal depression.

First of all, humans have a rhythm that they attune themselves to that defines when to go to sleep, when to be awake, and even when to be productive.  In case you haven’t heard of this rhythm before, it is commonly called your “circadian rhythm.”   In the winter, a person’s circadian rhythm can be thrown off drastically.  Think about it, you don’t get as much light as you do during the rest of the year.  It only makes sense that a person’s instinctual rhythm is thrown off when the sun only comes out for half the time that it used to.

Secondly, LED lights are easy to take with you.  Season affective disorder can turn up at any time throughout the day.  If you can carry the LED light with you, you will always have a treatment ready for when you are feeling the groggiest.

The best tool used to help S.A.D. in recent LED lighting news is called a Litebook LED and looks a little like this:

Simply by turning on these LED lights and facing them towards you every once in a while you will help keep a seasonal affective disorder from meddling with your life.  LED lights can reenergize you and make you as productive as you might be on a beautiful spring day.

Using Extrusions For LED Lighting

LED Extrusion

Extrusions are materials that have been formed to produce a specific cross-sectional profile. LED extrusions can be made from metal, such as aluminum, that has been heated and forced through a die to create a specified shape and profile.

These types of extrusions can then be used to attach LED lighting and provide an elegant and convenient means of placing lighting elements as well as having other advantages such as dissipating the heat that LED lighting produces.

Extrusions can be made in a wide variety of shapes and profiles and have been used to attach LED light tapes in cabinets, stairs, closets, floors and walls, among many other applications. Extrusions can be created specifically to fit the shape of the LED light and enable a designer to easily place LED lights exactly where they are required without the need of larger, more obtrusive, traditional light fixtures. Architects and lighting designers use extruded fixtures and enclosures to create specific design effects in finish and color that offer high structural integrity.

LED lighting is popular because it is highly energy efficient. It consumes only a quarter of the energy that is required by an incandescent bulb to provide a comparable level of lighting. In addition it provides a better quality of light and has lower maintenance costs because LED bulbs have a much longer life span.

The heat generated by LED lighting, however, is higher than traditional bulbs and thermal management can be a problem since it can affect the life span of the LED as well as the quality of light over time. While extrusions can be made from a wide range of metals, manufacturers have found that aluminium offers the best trade-off in terms of cost and heat dissipation to deal with this problem. While LED lighting mounting elements can also be made by die casting methods it has been found that extrusions are 50% more effective because they provide a higher level of conductivity.

Because extrusions can be created in a wide variety of shapes and profiles they can be used for mounting LED lights in a wide variety of applications including in interior design (stairs, bookcases, ceiling lighting and so on), advertising boards, exhibits and industrial lighting applications. The ability of extrusions to conduct heat away from the LED lighting and their versatility makes them the best choice for LED lighting applications.

LED Lighting Taking Over Grocery Stores

Grocery Store Switching To LED Lighting

You might start seeing LED lighting every time you take a trip to the grocery store. LED lights fit perfectly in refrigerated display cases, and a number of companies in the US are utilizing LEDs in their refrigeration units. This saves on energy costs and is good for business for all involved. LED lighting is taking over, and before long these lights will become a part of all our daily lives.

Refrigeration units are a perfect fit for LED lighting. Part of this has to do with the way the LEDs diffuse the light. Traditional fluorescent tubing sends the light in all directions, while LED lighting can be diffused directionally. This means the products being displayed in these refrigeration units are more brightly lit and look much better while on display. Coloring is evened out, making food packaging look more appealing.

Additionally, LEDs work well in refrigerated units because they are not affected by extreme temperatures (hot or cold), and since LED lighting gives off very little heat, the refrigerators do not need to pump out as much cold air to maintain temperatures. Not only are companies saving on energy with the lights themselves, but the refrigeration units are also able to become more efficient.

Surprisingly, even the quality of the food is improved by using an LED refrigerated lighting system. Fluorescent lights can create hot spots, which in some cases can raise the temperature enough to partially thaw the food. Keeping refrigerated food at the highest possible quality helps the supermarkets as well as consumers. Less food is thrown away, and customers are far happier when they know their food is safe and well maintained.

Major companies are taking advantage of this lighting system. Walmart has made a goal to use only LED lighting in all their stores. Companies who switch to LED refrigerated units see the savings generated and tend to replace the rest of their lights as well.

The maintenance involved in keeping these lights working is far less than traditional fluorescent tubing. A typical fluorescent tube in a freezer unit needs to be replaced about every six months. LEDs can last 50,000 hours, which translates to about 5 years.

Expect to see LED lights used for more than just regular lighting. Refrigerated lighting helps everyone involved save. Consumers can enjoy food that has been more consistently maintained, grocery store owners can expect savings in energy and maintenance, and companies who manufacture these units can see an increase in sales. LED lighting taking over grocery stores will help everyone save.

The Advantages Of LED Lighting Strips

LED Lighting StripsMany people have encountered LED lights in at least one form; usually in Christmas lights, computer electronics or solar powered garden lights. However, nowadays, not everyone is aware of the fact that LED home lighting is both available, and undoubtedly the future of household lighting. With over 30 years of experience, we at Klus are an industry leading manufacturer of LED lighting strips and linear fixtures.

Essentially, the difference between LED lights and conventional incandescent light bulbs is that the latter wastes as much as 98% of the supplied electricity as heat and shines light in every direction. By contrast, LED home lighting converts almost all of its supplied electricity into focused directional light, which is why it remains much cooler to the touch.

Another big difference is the ownership cost. LED home lighting lasts for an amazingly long time (for over 3 decades of regular usage) and costs such a small amount to operate that the electricity cost savings, over the lifespan of a bulb, will dwarf the bulb’s price. This contrasts significantly with standard non LED bulbs, which cost more than 500 times the price of the bulbs themselves, in replacement and operating costs.

These specific attributes (high efficiency, focused light and no fire risk) make LED home lighting an ideal substitute for spot lighting. This is particularly true for the halogen lamps found in lots of homes, because these waste an abundance of money and heat. Nonetheless, the task of replacing halogen lamps in the home is just 1 element of spot lighting suitable for LED lamps, as they make perfect display lights too. Even better, they can be installed in locations where you could not even consider using normal incandescent spot lights, due to the fire and damage risks from the high operating temperatures of traditional lighting.

LED spot lighting is a natural option for illuminating shelves, display units, inside clostets and cupboards, stair lighting and under kitchen units. It is easy to install next to surfaces and objects, without any risk of causing heat damage. Over all, the versatility of LEDs gives superior lighting to the lighting provided by standard light bulbs.

The Future Is Now For LED Home Lighting

LED Home LightingThe future is with us now. That is a declaration from the U.S. Department of Energy, which sees LED home lighting taking the forefront and saving homeowners money and cutting the nation’s energy bill by billions of dollars in the coming years.

LED, or light emitting diode, light has the power to cut energy use in the country by $30 billion in today’s electrical prices by the year 2027 as homeowners turn from the old incandescent lights and the disappointing compact florescent bulbs (CFLs). That would be equal to the annual output of 44 large power plants, according to the Energy Department.

Those are just the figures for home use. In the next two decades, LED use overall could cut electrical usage for lights by half at a cost savings of $250 billion and cutting 1,800 million tons of carbon emissions.

The proof of savings is in the trying. An Ohio man recently performed a year-long trial in which he replaced all the bulbs in his house with LED home lighting. While the initial investment was more than traditional lighting — LED light bulbs have fallen from their initial $50 a piece to about $10 now — he did cut his electric bill and so got a 41 percent return on that investment. When the fact that the bulbs are expected to last about 20 years is added in, that savings will be much higher over time, he estimated.

LED home lighting should be an easy choice for homeowners to make, whether they are concerned about the environment or just about their monthly electric bill. Consider that LED lights emit very little heat and so are much more energy efficient than their incandescent counterparts, which release about 90 percent of their energy as heat.

LED lights also come in a variety of hues. They can beam a bright white light in the kitchen or a bluish color that is easier on the eyes for reading. And LEDs are directional, which makes them perfect to aim at counter tops. For this reason, they also are increasingly being used as street lights, in parking garages, and for task lighting.

Other positive aspects of LED home lighting include their sturdiness, since they are constructed with epoxy lenses instead of glass; they will cast light for about 25,000 hours or more; they are small, so they can easily fit almost anywhere; and they contain no mercury, unlike CFLs.
