LED high mast lighting design

LED high mast lighting is very energy efficient and has a long service life. The LED technology continues to develop, and enables a more efficient, long lasting, and cost-worthy light source. The larger the area you want to light up, the higher your lights will need to be mounted on. If you need to illuminate large areas like airports, car parks or major roads, you'll need to use high mast lighting.

1、LED high mast lighting distribution
With LED high mast lighting, it's not just about how much light you get; it's about where it goes with traditional lights. Sources reflect as we used to put the light where IT was needed. Now With LEDs we can use lenses which give us even more precision to put the light just where IT's required and avoid light pollution
With LED high mast lighting, you often have neighbors in an area surrounding that depot or the yard. So you also have to make sure that you have minimal tilt requirements. And that's usually achieved through optic lenses.
You may have cars, trucks, or even planes moving about beneath your lights. You don't want to serve them with glare. Similarly, if there are houses nearby, you don't want to disturb them either.

2、Color
Old fashioned sun or sox lamps gave an orangey glow which made it difficult to recognize colors properly. Nowadays with HID and LED lights the lights white, which means you get much better color rendering 

3、Maintenance
When you've got light mounted up this high, you really don't want to have to change a lamp if you can possibly avoid it. So make sure you choose a product that's going to last you a long time and make sure you quiz the manufacturer on how long its really going to last. Are you getting a warranty with the product and what does the lifetime of the product really mean if they say fifty thousand dollars? Is it going to die after fifty thousand hours? Or has it just lost some of its output? Ask these questions of the manufacturer and if you're not happy with the answers pick another manufacturer

4、Control
 You can save loads of energy by turning your lights off automatically or dimming them in response to time or movement all levels of light.
We think about with LED opens up a whole new world have been out a dim control LED and look at different ways of being more flexible within a working environment. Gone other days when it took ten or fifteen minutes for light slightly used to warm up and we no longer have the problem of warm restrike when you had to wait a long time after turning lights off before you could put them back on again with LEDs you can switch them on and off as often as you like.

5、Retrofitting
Retrofitting new LED lights to existing columns is fairly straightforward these days, which makes upgrading to new technology that be easier. And with LED lights you can spread the weight of the loom and as on your columns more easily because you can direct the light more carefully in the direction you want it to go.

LEDs are mainly used in street lighting

Foreign lighting titans including Philips Electronics NV (PHG.AS), Osram - partly owned by German engineering conglomerate Siemens AG (SIEGn.DE) - and General Electric Co (GE.N) should emerge as winners due to their financial clout and technical expertise, industry experts say.

Philips and Osram, which have traditionally focused on conventional lighting in China, have ramped up production of LED high bay light. Osram, which employs 8,000 people in China, started construction of its first-ever LED chip packaging plant in China in August, a 100,000-square-metre complex in the eastern city of Wuxi, using chips made in Germany and Malaysia.

LEDs are mainly used in street lighting, shopping malls, upscale hotels and office buildings. To accelerate a broader shift to efficient lighting, China in October started to phase out wasteful incandescent bulbs, joining other countries like the United States and Japan.

The diodes, semiconductors that convert electrical current into light, are much more efficient than the two dominant products for home and commercial lighting, compact fluorescent lamps (CFLs) and incandescent bulbs. LED lights are longer lasting and up to 10 times more efficient than incandescent bulbs.

LED chip makers use sapphire wafers

Currently, almost all LED chip makers use sapphire wafers, while few of them are willing to change production equipment to adopt GaN-on-Si epitaxial wafers. However, he emphasized that GaN-on-Si technology is a long-term development for large-size LED epitaxial wafers.

MD of LED Lighting Depot Andrew Littler said: “We’ve got two clear advantages over our competitors: a Payback Calculator that helps consumers make informed decisions about their purchases; and an exclusive range of high-quality bulbs in the form of the Lumaera range – which offer great value for money and feature Phillips LEDs.

“Unlike other LED retailers, our confidence in the range of products we stock means that we also offer a Five Point Promise covering Quality, Reliability, Savings, Certification and Value. Industry-leading warranties and accurate technical specifications are just two of the areas the Promise covers – giving consumers complete peace of mind that they are buying a durable, high-performance bulb.”

The Payback Calculator works by incorporating the total wattage amount for items in the basket, how many hours per day the lights are used and for how many days per week, as well as the amount per unit of electricity the customer pays. It compares these details with the equivalent cost for filament lighting products to give an annual saving amount, payback period for the investment in LED bulbs and the total lifetime saving made by switching to LED lighting.

while promoting environmental sustainability

Together, Cree and ALT have overcome the technical challenges of providing a warmer colour, at a temperature of 2200K, while maintaining a high luminous efficacy, especially with indoor applications such as restaurants and galleries. In fact, the A55 bulb and PAR lamp, from ALT, were specifically designed for exactly this type of market, where the lighting must not be harsh or intrusive or distort the illuminated area's ambient colour tones. At the same time, the Cree? XT-E 2200K CCT LED retains all the power-saving properties of LED lighting technology, enhancing the value proposition for customers, while promoting environmental sustainability.

"Cree is the market leader in LED technology, offering its customers innovative technology and excellent, high-performance products," said James Liang, CEO at ALT. "ALT has been collaborating with Cree for over five years now, and use of Cree's products has consistently allowed us to better position ourselves in the market. A recent design win with a restaurant at a top tourist destination in Mexico, Playa del Carmen, is a perfect example implemented by CB LED Iluminación (one of ALT’s top distributors). The restaurant's clientele like a warm, calm light that perfectly complements their relaxed mood while they sample the delights of a Mexican menu. Our MR16 lamp delivers on that promise. At the same time, the restaurant management, by using 7W ALT LED lighting, is saving 85 percent of the energy that would be consumed by the alternative option, 50W halogens.”

ALT is a pioneer in the use of Cree LED products and a loyal customer who uses Cree LEDs in most of its product designs. ALT's MR16 lamp is the first Cree XT-E 2200K LED design win in Taiwan and it demonstrates how effectively the two companies have cooperated to advance LED technology and how Cree's technology and products can help its customers achieve their market objectives.

"Teaming up with ALT, an LED lighting manufacturer who has won three of the world's major industrial design awards, has been a very rewarding venture for us,” said Soo Ghee Lee, Cree Managing Director, Asia. "LEDs are a global trend, reducing resource consumption, promoting energy conservation, and can help to reduce the cost of doing business. LED lighting is not only cost-effective, it is eco-friendly."

Making it easier for drivers to locate their vehicles

The anniversary is a good time to take a closer look at the results and lessons learned, with more than 80% of the LED fixtures planned for phase one deployed. The lessons learned are based on a presentation delivered by Ed Ebrahimian, Director, Los Angeles Bureau of LED high bay light, to the IES Street and Area Lighting Conference convened in Miami in September 2012.

Noribachi replaced the fluorescents with the popular LOWBAY vapor proof fixture. The new lights use about half of the energy while emitting a much brighter, cleaner light. Inside the parking structure this translates into an increased feeling of security and heightened color perception, making it easier for drivers to locate their vehicles.

Lining Manhattan Beach Boulevard, the City’s main thoroughfare, are historic lantern fixtures that also required an LED upgrade. This application demanded a retrofit of the lantern fixture to maintain the original aesthetics. In order to achieve this Noribachi created a custom LED solution designed to easily sit in the existing housing. Noribachi’s experience in diffusion allowed engineers to direct the light straight down inside of the existing lens, creating a glowing effect and shielding the individual diodes from view. Noribachi also used LEDs with a warm white color temperature to match the historic ambiance.

The showroom has been carried out in collaboration with the Austrian practice Innocad Architektur ZT and the UK’s Space Group Architects. The luminaires on show include XAL’s Helios which is shortlisted in the interior category for the 2013 Lighting Design Awards.

who rated purchase price as the most important factor

Many consumers will make their first LED lamp purchases in the next few years, and the market is entering a critical window for making a positive impact on consumers’ first impressions of LED technology,” said Eric Kim, CEO of Soraa. “However, for LED high bay light to achieve significant market share, consumers must be confident that these lamps can give them the light quality they need and want. With the emergence of next generation LED technology, these performance benchmarks have now been reached.”

McKinsey’s 2011 Lighting the Way report suggests that consumer and commercial lighting purchase decisions are driven as much by light quality, as they are by the cost of the light bulb. Twenty percent of the residential respondents in the McKinsey report rated light quality as the most important decision criterion for lamp installation – which is on par with the 22 percent who rated purchase price as the most important factor. In all other market segments, light quality was by far the most important criterion.

“The slow market adoption of CFLs over the last 20 years demonstrates that simply because a product produces enough light, saves energy and is cost-effective, broad market adoption of that technology is not ensured. To persuade consumers to purchase LEDs instead of incandescent lamps, LED lamps must be seen as high-quality products worth the initial higher price differential. Therefore, LED lamps must closely replicate the color rendering and color appearance of the incandescent and halogen lamps that they replace,” said Carlos Alonso-Niemeyer, Energy Efficiency Program Manager of NSTAR a Northeast Utilities Company.

EPA pointed out in their latest draft lamp specification that lack of LED lamp color quality is a potential barrier to broader consumer adoption of energy efficient lighting. However, EPA went on to say that it will continue to monitor the market and explore opportunities for improving color quality and consistency of lamps in the future. Given the critical importance of this issue to increased adoption of LED lighting, groups told EPA that the time to address higher color rendering is now.

“Designers should have the flexibility to select the appropriate source for their applications and end users should have their right to purchase high color rendering or full spectrum lamps for their spaces,” said Chip Israel, President of the Lighting Design Alliance.
