LED Light Bulbs: An Innovative Alternative to Traditional Lighting

Is LED lighting right for you? You've probably heard of LED lights before, but you may not know much about them. We've taken the time to compile some of the biggest advantages to LED lighting, so read on to find out why everyone is talking about this new technology.
Longer Life
Normally it is believed that LEDs have a seemingly infinite lifetime. However, their actual life is around 50,000 hours which makes them usable for around 17 years. This life span is 50 times that of incandescent and 25 times that of halogen bulbs.
Low Power consumption
A properly designed LED is around 80% efficient, which is incomparable to incandescent bulbs who have only 20% efficiency.
No Harmful Radiations and Emissions
Unlike CFLs and fluorescent lights, LEDs do not emit any infrared or UV radiations, neither do they contain any mercury. LEDs also resist vibrations and shocks and thus operate effectively.
Reduction in monthly bill
Owing to the reduction in power consumption, LED lamps also significantly reduce electricity bill. Replacing a single incandescent bulb or fluorescent light by an LED lamp can cause a considerable reduction in your yearly bill. 
Some Disadvantages:
There are some issues with LED lighting as well, so make sure to consider the following points before making 
High cost
LED technology is entirely a new technology under research and development phase. Due to this, LEDs are normally more costly than other lights. However, the non-replacement benefit, reduction in bill, and other benefits of LED lamps compensate their high cost.
Less Variety
At present, LED lamps have a limited variety, unlike other lights.
In short, LED light bulbs are really a great and emerging technology that can surely provide long term benefits to the consumers.

How are LEDs work inside?And will more consumers see the brighter prospect of LEDs?

LEDs last between 40,000 and 95,000 hours, and if an LED operates for 12 hours daily this would potentially give a life span of approx 20 years.

An LEDs longevity all comes down to the question of lumen depreciation. Some experts reckon that once an LED reaches 30% depreciation its lifespan is pretty much over, although in fairness it will continue to work but with reduced light output.
Not surprisingly one of the key operating factors impacting LED lifetime performance relates to the temperature at the junction where the diode connects to its base. The theory is simple enough. Keep junction temperatures low and the rate of lumen depreciation decreases. What’s needed here is effective heat dissipation designs and there are plenty of those around. The real design challenge is that most LEDs are contained within a resin that is just not that good at letting heat go.
The heat that LEDs generate stems from the P-N junction that is created in semiconductor–based devices.
As electrons travel in the structure of the semiconductor they fill electron holes and emit photons, a form of light. The heat developed at the P-N junction is actually electrical energy that has not been converted into light. It is imperative that this heat be conducted away via conduction, convection or radiation methods.
So LEDs must efficiently transfer as much heat as possible away from the P-N junction because a heat-stressed LED will lose efficiency and light output will diminish and could possible fail altogether. So what is the recent breakthrough that will add to consumer confidence? Well, it involves a claim that LED system costs can be cut by 40% which is no mean feat.
The LED Bulb of  EUROLEDS SARL. 
A recently launched market research report at MarketResearchReports.com reports the market forecast of the Asia Pacific consumption of light emitting diode (LED) lamps in General Lighting applications, which mentions the forecast from 2014-2019.
Lewes, DE -- (ReleaseWire) -- 03/05/2015 -- The market forecast is segmented by 8-major LED Lamp categories and 3-major End-User categories: Government, Commercial / Industrial and Residential. The study also provides a detailed forecast by geographical segments: China, Korea, Japan and Rest of Asia.

According to this report – in 2014, the APAC region consumption value of LED lamps, which are used in General Lighting, reached USD 2.72 billion and would be increasing to USD 6.67 billion in 2019. Market forecast data in this report refers to consumption (use) for a particular calendar year; therefore, this data is not cumulative data. The consumption value will increase with strongly rising quantity growth partially offset by declining average prices. All values and prices in this report are at factory-levels, and are in current dollars, which include the effect of a forecasted 5 percent annual inflation rate over the forecast period.

General Lighting Stationary Applications: General Lighting is lighting that is used to provide the main illumination of an area. It includes Directional Lighting, Supplementary Lighting and Architectural Lighting in the General Lighting category. In 2015, "architainment lighting" – a blend of architectural and event lighting has been added to the General Lighting segment. LED lamps used in signage (digital sign boards) and displays (back-lighting units for LCD/other screens) are not included in the General Lighting segment; however, lamps used in display windows or display cases (for example: retail store displays) are now included in the General Lighting segment. LEDs in signals (for example traffic signals), portable flashlights (torches) and decorative Christmas/holiday lighting are not included in the market forecast data for this study.

LEDs are used in both functional and decorative light fixtures, with an advantage of energy savings. Compared to incandescent lighting, LED-based solid-state lighting (SSL) delivers visible light with reduced heat. In addition, its solid-state nature provides for greater resistance to shock, vibration and wear, thereby significantly increasing its lifespan.

According to this report, General Lighting LED lamp consumption in APAC is forecast to reach USD 6.67 Billion in 2019.

Bulbs put everything in a new light

By 
Published: 
I first tested an LED bulb eight years ago. It was not a promising beginning.
The bulb was a Par 38 spotlight for a recessed ceiling fixture. The color of the light was a silvery metallic — so chilling and wintery that it made the room feel cold. The final kicker was the price — $125.
Things have changed a lot since then.
As LED manufacturers have increased the efficiency of the bulbs, the prices have fallen precipitously. (At Home Depot, Lowe’s and Wal-Mart, for instance, today’s price for a 90 watt-equivalent Par 38 spotlight is $20 to $30 — 75 to 85 percent less than the one I tried in 2007).
At the same time, the quality of the light produced by today’s LEDs has vastly improved. In my most recent annual home testing, I found that the light produced for most of the bulb categories can be extremely close to that of the incandescent and halogen bulbs the LEDs are designed to replace — so much so that only a lighting expert will notice the difference.
Moreover, the bulbs are so long-lasting — more than 22 years if used for only three hours a day, the average use per bulb per day in most U.S. households — that some manufacturers have incorporated the LED into the fixture itself. When the light finally gives out, you get a new fixture.
As part of my home testing, I installed a GE flush-mounted ceiling fixture in my laundry room. Not only does it look much better than the 50-year-old fixture it replaced, the light it produces appears to be brighter and softer than the 75-watt equivalent compact fluorescent I had been using, even though the new fixture actually produces less light.
If you have yet to purchase your first LED bulb, the best place to start is the A19- and A21-size bulbs, which replace the 40-, 60-, 75- and 100-watt incandescents that are no longer made.
With an LED made by a major brand, the transition should be easy. When I compared GE’s, Philips’, Cree’s and Sylvania’s most recent generation of Energy Star-rated A19 and A21 bulbs with several incandescents that I am hoarding for my home testing, I found the light produced by the LEDs to be remarkably close to the old-style bulbs. GE’s A19 60-watt equivalent Energy Star-rated LED and its 60-watt incandescent are indistinguishable.
There is a second type of LED bulb available in the A19 and A21 size that did not exist as an incandescent called “daylight.” The light produced by these LEDs is blue-white and resembles daylight, hence the name. The daylight bulbs are more popular in some parts of the United States than others, especially in the Midwest with its long, gray winters, said Pam Price, retail marketing manager at Sylvania.
The daylight bulbs are also popular with older buyers because their blue-white light heightens contrast and makes reading easier, added Mike Watson, vice president for product strategy at Cree. Testing this for myself, I tried reading several types of publications under an A19 60-watt equivalent Energy Star daylight bulb. The light definitely did heighten the contrast, most noticeably when I read a newspaper.
When I started testing other types of LED bulbs in my house, the transition from halogen or incandescent was not as seamless as I expected. With the other LED categories, there are additional variables to consider, and in some cases the issue was not the LED but the particular conditions in my house, such as ceiling height. Before you start testing the other types of LEDs, you need to be conversant with these two LED basics:
• Lumen number: This indicates the brightness of the bulb. With the A19 and A21 LED bulbs, the lumen numbers are nearly the same for each wattage equivalent across all manufacturers. The A19 60-watt equivalent LED has 800 lumens, the A19 or A21 75-watt equivalent has 1100 lumens and the A21 100-watt equivalent has 1600 lumens. But within the other bulb categories, the lumen number can vary from brand to brand. When the lumen difference is small (5 to 15 percent), you won’t notice. But if the lumen difference is large — and it can be as much as 50 percent — you will definitely notice. The lumen number is always on the front of the packaging in big print.
• Kelvin temperature: The Kelvin temperature scale measures the color temperature of the light. With incandescent and halogen bulbs, Kelvin temperature has never been an issue, because it is the same for each bulb type — all incandescent bulbs are 2700K and all halogens are 3000K. Unlike those bulbs, the LEDs can have a Kelvin temperature of 3500K and 5000K. Even more confusing for consumers, the Kelvin temperature can vary within the same LED bulb category, ranging from 2700K (mimics incandescent and appears to be yellowish) to 3000K (mimics halogen and is whiter) or 5000K (daylight that looks blue-white). The differences are very noticeable, and the higher temperatures appear to be brighter even when the lumen number is the same. The Kelvin temperature is usually on the front of the packaging; you can always find it in the “lighting facts” box on the back.
Although LEDs are now available for most residential lighting fixtures, I focused on the bulbs designed for the fixtures that are among the most widely used, including recessed ceiling fixtures, track lights, bathroom strip lighting and chandeliers.
For recessed ceiling fixtures, commonly known as “ceiling cans” because they look like coffee cans pushed up into the ceiling, there are two LED options: “floods” that provide general illumination throughout the space, and “spots” that can inject some drama because they only illuminate the area directly beneath the fixture and the light at the center of the illuminated area is much brighter than the light at the edge.
Because there are so many choices here — I tested nine floods and eight spots — the issue for most people will likely be “which one is right for me?” You can simply switch out what you’re using now for the LED version or experiment.
Within the floodlight category, the main difference between the BR30 LED and the BR40 LEDs that I tested is the amount of light produced. With 1100 lumens, the BR40 LEDs are about 40 to 70 percent brighter than the BR30 LEDs. In a two-story space they’ll “wash” the walls and ceiling as well as the floor.
But for a living room like mine with an eight-foot ceiling, the BR40s were much too bright; the BR30s were a better choice for background lighting. But, within that subcategory, there are still further refinements. All four brands of BR30 that I tested offer a 5000K daylight version (the light was too blue and ethereal for me), Sylvania’s BR30 has 10 to 25 percent more lumens than the other BR30s, which makes the room brighter, and GE’s BR30 Reveal has special filters that make the colors appear more vibrant.
With the Par 38 LED spotlights, there’s another variable to factor in - the size of the illuminated area below the bulb, which depends on the beam angle of the light. When the beam angle is in the 40-degree range, more floor area is illuminated. When the beam angle is in the 25-degree range, less floor area is lit but the light is more concentrated and the effect more dramatic.
With an eight-foot ceiling and recessed cans about six-feet apart, I found GE’s and Sylvania’s Par 38 LEDs with fewer lumens (950 and 1050) and the wider 40-degree angle worked best because they provide both ambient and task lighting. When a sofa is placed directly below the ceiling cans, the brighter central area of light can accommodate reading so I don’t need table lamps.
But were I to put Par 38 LEDs into a two-story space, I would opt for Cree’s with a narrower 25-degree angle and more lumens (1500) to maximize the amount of light reaching the floor. Because all the light from the Par 38 bulb is focused downward, the walls and ceiling would not be lit at night, but this can make a large volume space feel smaller and more intimate. At the floor level, the light would not be bright enough for reading, so you would need to add a few table lamps.
The Par 20 LED spotlights that I tested fit onto a track light fixture. These bulbs are most often used to light artwork. For the three brands I tested, GE, Sylvania and Philips, the range of color temperature (2800 to 3500) and beam angle (20 to 40 degrees) offered a lot of choice. In my stairwell, Philips Par 20, 25-degree angle, 3000K made the African sculptures that I have displayed there really pop. For the stairs, GE’s Par20 softer 2700K, 25-degree angle LED was perfect. Sylvania’s Par 20 3000K 40-degree beam angle was too wide for this spot and Sylvania’s Par 20 3500K 25-degree angle was too bright.
For the Hollywood strip lighting above my bathroom mirrors, I tried GE’s and Sylvania’s “decorative” G25-size, globe-shaped LEDs. GE’s 2700K version with 350 lumens provides soft, even light that is nearly identical to the incandescent bulbs I had been using before.
Sylvania’s version is brighter with 440 lumens and a higher 3000K Kelvin temperature. For a master bathroom with two spouses using the sinks at the same time as they get ready for the workday, Sylvania’s brighter bulbs could be preferable, especially for applying make up.

10 Lighting & LED Trends For 2015, According To IHS

Leading analytics company, IHS, has forecast 10 trends that it believes will propel the lighting and LED industry through 2015, which it believes could lead to improved margins for companies and lower prices for consumers.
“For the big three lighting suppliers, the road was bumpy: all of them recorded falling revenue in the first three quarters of 2014,” said William Rhodes, research manager of lighting and LEDs at IHS Technology. “Industry watchers are now looking to see if these giants of the lighting industry can turn the tide in 2015.” light bulb ban
The top predictions are as follows:
  1. China–the LED dragon–will continue to grow
  2. The sky is the limit for cloud-based smart lighting
  3. Changing fortunes for lighting companies expected in 2015
  4. Li-Fi, a brighter way to communicate
  5. Is lighting poised for a quantum leap?
  6. OLED luminaires, and where to purchase them
  7. LED filament bulbs: incandescent beauty with an LED twist
  8. Packaged LED industry is moving downstream and getting smarter
  9. Is your streetlight all that it seems?
  10. Automotive applications driving potoelectronic components market
And with the rise of the consumer electronics industry making LED lighting a ‘new’ and ‘cool’ toy–thanks to remote-controlled lighting from your smart-phone–the future for LED and lighting companies is … bright.
One of the takeaways from the IHS press release, which notified the release of an accompanying (though mysteriously absent) white paper, is the impact that the reorganisation of the top three lighting companies will have on the industry, with IHS predicting that it could turn the top three companies “into pure-play lighting companies focused on dynamic markets.” Such restructuring, says IHS, “will also allow LED makers to raise capital for further investment.”
“Changes in the corporate structure, could lead to improved margins for the companies, and possibly lower-priced products for consumers,” Rhodes said.
And while IHS doesn’t necessarily agree that cloud-based smart lighting will gain market share in 2015, it does agree that increased marketing of such consumer electronic gadgets could create mindshare in 2015, “positioning the market for future growth.”
