LED technology has evolved as very efficient solution for all our lighting needs in our homes, offices, parking lots, industries, streets and many other areas. However the application of LED as LED Industrial light, LED flood light and LED parking light is the biggest revolution as it has cut down the energy requirement significantly and offered a very durable lighting option that can last for years without needing replacement. The use of LED in industries and streets offers a very high quality lighting solution at reasonable cost. In fact, the lifetime cost of LED turns out to be much lesser than the HID lighting, which is gradually being replaced by LED. One of the main reasons for lesser lifetime cost is the long life of LED with very low power consumption. LED lighting offers a very promising solution for our future as the cost of LED will continue to drop as it has in the last few years because of the improving manufacturing techniques providing more efficient and cost effective production of LED for industries. LED light systems, like LED flood light systems offer many advantages over traditional lighting. Some of them are as follows: 1.    Extremely low power consumption2.    Long Life of Lights leading to excellent life for overall system3.    Excellent ability of color rendering according to the application 4.    Higher initial cost but better lifetime cost as compared to any other option.LED industrial light not only offers a very efficient alternative but also an environment friendly options that will help us cut down on the critical carbon emissions leading to a better future for the upcoming generations. The main reasons that make LED Industrial Lighting a perfect solution are as follows:Long Life: In terms of life expectancy, LED lighting turns out to be 20 times better as compared to the incandescent bulbs. The average life of LEDs is about 60,000 hours whereas a normal incandescent bulb lasts for about merely 1500 hours on an average. When compared to fluorescent bulbs. LEDs last 10 longer which is still a significant difference.Low Power Consumption: When it comes to power, LEDs offer a very efficient option with extremely less power consumption. It is estimated that by using LEDs in US, about 348 terawatt hours of electricity can be saved which costs huge amount of $30 billion. Better Distribution of Light: LED Lighting offers much better focusing properties which results in better distribution of light in the desired direction as compared to other sources of light which throws the light in every direction resulting into wastage of energy. Reference:ASMT-UYBG-NACJ8XRCWHT-L1-0000-004E6LCWW5AM-KXKY-4U8X 

Emergency lights assist the vehicles allocated for emergency response services to do better. Emergency lighting units are essential not just as a supplementary light supply, but also as a reliable guide to the normal public. However, LED lights are the most productive emergency lights that can assist emergency vehicles accomplish their responsibilities without inhibitions. Employing diverse colored lights for emergency vehicles boost their competence as guiding lights making them noticeable. Emergency LED lights come in several diverse colors to help the emergency vehicles direct the traffic and employ them as supplementary lighting systems. They're accessible in colors like blue, red, gree, yellow and amber, which can be employed individually or merged into one lightbar. Blue LED lights are most standard lights which can be noticed on police cars, and emergency ambulances.Blue LED lights are also the most productive when merged with other colored lights. Police vehicles employ these in combination with the red light emitting diodes to aware the general public about the emergency circumstance, or execure their patrolling responsibilities without any issues. Different colored LEDs can be assembled to blink in several diverse outlines that make them noticeable from nearly a mile. Though single colored light emitting diodes are noticeable from a distance, blinking manifold colored lightings make superior visual effect and convey the message very clearly. For instance, blue & red blinking ones from the police vehicles demands the right of way when there's a continious chase. Several other emergency cars employ the blue LEDs in numerous diverse forms. As strobe lamps, they're strong portable light supplies when required. As fully-fledged light bars, they could be apparanelty visible in the heavy traffic areas. They also available in the form of elaborated lightbars with built-in traffic advisers, which could direct traffic to take diversion ahead and avoid the emergency area.The blue lights made of LEDs can also be very productive dash lights which are rather essential for each emergency cars. Dash lights not just employed for undercover police cars, but are also essential for the security of emergency cars. They can perform as tail lights while the emergency cars stop at the emergency area, making them noticeable to other automobiles.These days blue LED highbay lights can be easily noticed in many of the pavements of your country due to their powerful lighting features.LED lights can surpass any other type of lamps and use less power than other types of illumination. This makes them the 1st option for emergency vehicles, since they require to maintain the lights burning for many hours. Purchasing them from the appropriate retailer assure the longest life span.Reference:KY59-EB-251KY59-LRW5SM-GZHZ-1KY59-LRW5SM-HYJY-1-Z

Thermal Solution Resources, LLC (TSR) introduced the world's smallest wireless LED lamp – the intelliSSL MR16 – which can be controlled remotely from IOS, Android or Windows smartphones, tablets or PCs. The intelliSSL lamp incorporates an ultra-compact driver architecture with a powerful antenna system, designed to maximize reception strength, and uses the ultra-low-power JN5168 wireless microcontroller from NXP Semiconductors N.V.. The TSR intelliSSL wireless MR16 lamp will be featured in the NXP booth this week at LIGHTFAIR (no. 2453) and the LEDdynamics booth (no. 100), as well as the ZigBee Alliance booth (no. 3251) as part of a ZigBee Light Link network. The patent-pending intelliSSL design provides strong wireless reception, eliminating signal interference even under high temperatures, while conforming to a standard ANSI format – 1.98 inches in diameter and 1.98 inches in length – with a GU 5.3 base. A GU 10 base version is planned for release later this year. Compliant with the IEEE 802.15.4 standard for wireless communication, TSR's new wireless MR16 LED can be used with a wide range of network software stacks, including ZigBee Light Link, ZigBee Home Automation and JenNet-IP. The intelliSSL smart MR16 LED is ideal for commercial, architectural and outdoor lighting installations, as well as general lighting applications.

A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally for cheap and efficient lighting.The proof-of-concept device takes advantage of the latest nano-scale materials and processes to emit green and red light separated by a wavelength of 97 nanometres—a significantly larger bandwidth than a traditional semiconductor.Furthermore, the device is much more energy efficient than traditional LEDs as the colours are emitted as lasers, meaning they emit a very sharp and specific spectral line—narrower than a fraction of a nanometre—compared to LEDs which emit colours in a broad bandwidth.One of the main properties of semiconductors is that they emit light in a certain wavelength range, which has resulted in their widespread use in LEDs. The wavelength range in which a given semiconductor can emit light—also known as its bandwidth—is typically limited in the range of just tens of nanometres. For many applications such as lighting and illumination, the wavelength range needs to be over the entire visible spectrum and thus have a bandwidth of 300 nm.Single semiconductor devices cannot emit across the entire visible spectrum and therefore need to be 'put' together to form a collection that can cover the entire range. This is very expensive and is, to a large extent, the reason why semiconductor LEDs are not yet used universally for lighting.In this study, the researchers, from Arizona State University, used a process known as chemical vapour deposition to create a 41 micrometer-long nanosheet made from Cadmium Sulphide and Cadmium Selenide powders, using silicon as a substrate.Lead author of the study, Professor Cun-Zheng Ning, said: "Semiconductors are traditionally 'grown' together layer-by- layer, on an atom-scale, using the so-called epitaxial growth of crystals. Since different semiconductor crystals typically have different lattice constants, layer-by-layer growth of different semiconductors will cause defects, stress, and ultimately bad crystals, killing light emission properties."It is because of this that current LEDs cannot have different semiconductors within them to generate red, green and blue colours for lighting.However, recent developments in the field of nanotechnology mean that structures such as nanowires, nanobelts and nanosheets can be grown to tolerate much larger mismatches of lattice structures, and thus allow very different semiconductors to grow together without too many defects."Multi-colour light emission from a single nanowire or nanobelt has been realized in the past but what is important in our paper is that we realized lasers at two distinct colours. To physically 'put' together several lasers of different colors is too costly to be useful and thus our proof-of concept experiment becomes interesting and potentially important technologically."In addition to being used for solid state lighting and full color displays, such technology can also be used as light sources for fluorescence bio and chemical detection," continued Professor Ning. 

With the ICL5101, Infineon Technologies AG extends its portfolio of lighting control ICs, addressing lighting systems in the range of 40W to 300W. The new high-voltage resonant controller IC provides a high level of integration which translates to a reduction in system cost. Typical applications which benefit from these features include indoor and outdoor LED lighting, high-bay and low-bay lighting, street lighting, parking garage and canopy lighting, office lighting, retail and shop lighting. Since the total cost of ownership is an important aspect for industrial lighting, customers prefer to use resonant topologies supported by the new ICL5101 due to its high efficiency up to 95%.  The highly integrated ICL5101 allows for advanced LED driver designs with approximately 25% less components compared to similar solutions which require separate PFC and resonant ICs. This leads to smaller form factors with more reliable designs, less complex PCB layouts and reduced costs. The ICL5101 integrates the half-bridge and the PFC gate drivers. All operation parameters of the IC are adjustable by simple resistors, enabling cost effective but reliable and stable parameter-settings.The chip supports outdoor use by an extended junction temperature ranging from -40°C to +125°C.The LED controller ICL5101 is designed to control resonant converter topologies such as LLC. The integrated digital PFC stage operates both in critical conduction mode (CrCM) and discontinuous conduction mode (DCM), which allows an extremely stable regulation in low load conditions, occurring for e.g. when the device is dimmed. The LED lighting can be dimmed down over an extremely wide range from 100% to 0.1% of its nominal load. State of the art dimming today typically ranges from 100% to 5%. In addition, the ICL5101 enables an ultra-fast time to light – under any conditions – with less than 200ms.The adjustable PFC stage of the ICL5101 delivers high power quality, providing a low total harmonic distortion (THD) of less than 10% and a high power factor of more than 0.99 over wide line input voltage range. This enables lighting manufacturers to comply with energy efficiency standards. Furthermore the output of the ICL5101 is extremely stable over line voltage variations. A comprehensive set of protection features including external over temperature protection and capacitive load protection ensure the detection of fault conditions and increase system safety.With the introduction of ICL5101 Infineon once again demonstrates its technology leadership for highly efficient driver solutions. Just recently, the ILD6150 step-down driver IC was nominated as finalists in the product category "ICs and electronic components" for the 2015 LEDs Magazine Sapphire Awards .  

What if you could stick an OLED panel on your wall with a magnetic mat? A detachable OLED (organic light-emitting diode) panel that would just as easily be taken off as stuck on the wall? Reports surfaced on Tuesday that South Korea-based LG Display has fashioned just the thing, a 0.97 mm thick 55" flat OLED TV panel and only 1.9 kilos (4.2 pounds). LG Display showcased the screen in Korea.By comparison, LG Display's existing 55-inch OLED panel is 4.3 mm thick. Engadget's Jon Fingas said that "it raises the possibility of big-screen sets that easily blend into your living room's décor." That's the good news. The sad news is that there is no word about when such displays will make it to retail shops.The unveiling was part of a broader announcement to showcase the company's plans for the future, which center on OLED tech, said Don Reisinger in CNET. The screen was presented as one of the company's future displays at the media event. Using a magnetic mat, the screen can easily be stuck to—or removed from— a wall. To remove the display from the wall, said Reisinger, you peel the screen off the mat. The Yonhap News Agency report carried a photograph of a model gently lifting the detachable wallpaper OLED panel at the event in Seoul on Tuesday. Yonhap News Agency referred to the LG Display screen as a "wallpaper OLED panel." Don Reisinger of CNET referred to it as press-on wallpaper TV.Strategically, the unveiling tells us something about LG Display, said reports; the company appears to view high-end displays as a growth engine. (They released 55-inch, 66-inch and 77-inch OLED models earlier in the year, said Yonhap News Agency.) The showing also indicates that LG Display continues to focus attention on OLED.Reisinger offered reasons for why OLED "is widely believed to be the next frontier." He said, "The technology adds an organic compound layer that allows not only for exceedingly thin screens, but for those displays to be curved. The organic material also emits its own light, eliminating the need for a backlight. That allows for such thin screens and has made OLED a desirable choice not only for televisions, but for a wide range of wearables and other mobile products."While the wall-sticking panel is a delight to view, Ryan Waniata, writing in Digital Trends on Tuesday, expressed his view that "Such a display probably won't be used in a TV anytime in the near future; it's more likely to end up in wearable technology, automobile manufacturing, and commercial applications." Still, he added, "we could conceivably see such technology (paired with an outboard processing unit) becoming the TV of the future."
