ONE year after, the Director General of the Oyo State Signage and Advertisement Agency (OYSAA), Yinka Adepoju, has scored its agency performance as near excellent.

In a statement to commemorate the first anniversary of the agency, Adepoju, who praised the Governor Isiaka Abiola Ajimobi for establishing the agency and giving it the necessary support, stated that the agency is not only fulfilling the purpose for which it was set up, but also taking on vision.

"On a personal note, let me commend our God chosen leader, the people's governor for the tremendous success recorded so far in his administration's Transformation, Restoration and Repositioning agenda. You are a light to many of us, please keep the light always shining.

"For us at Oyo State Signage and Advertisement Agency (OYSAA), I make bold to say that Oyo State is well on its way to achieving environmental standards and best practices, a novel trend which other states are already emulating."

He said that in the one year existence of the regulatory outfit, it has successfully cleaned up the major routes in Ibadan ditto Oyo and Ogbomoso by removing sub standard, dilapidated, dangerously and badly positioned billboards.

"These cities are now clean, very calm and wearing new looks. We hope to replicate this in other major towns of the state especially now that the State Government has graciously approved for our Agency new set of operation equipment. This development has positively enhanced our performance level."

He listed the achievement of the agency to include registration of outdoor practitioners in line with agreed categories; regularization of 1st Party and 3rd Party structures and removal of illegal boards and structures; creation of an outdoor advertisement environment of a world class standard as billboards are now environment friendly in the state; effective sensitization of the industry players and the general public; creation of a well defined Data Base with records of every signage and other advertisement structures in the state; smooth and seamless deployment of modernized structures and landscaping the surrounding areas of such; creation of more environmentally complementing outdoor advertising formats which have assisted greatly in the area of revenue generation.

According to him, in moving forward, the agency hopes to adopt the Public Private Partnership (PPP) initiative judging from the meagre resources available to the state government and its thirst in providing excellent social service delivery to the people in order to enhance the socio-economic activities of the state.

He mentioned provision of solar powered street light poles; construction of Ultra Modern Bus Shelters (Bus Stops); installation of advert based street directional signs and house numbering exercise; branding of newly acquired government buses; branding of public places like parks and gardens, markets, garages and roundabouts; deployment of LED electronic video display boards in strategic locations of the state capital to which concessional approvals have already been granted to about ten practitioners, as upcoming projects and programmes.

"A practical demonstration of this is what you see on Parliament Road leading to the state secretariat. This is the first of its kind, more of such are under construction and very soon will emerge and add value to the global beautification exercise currently going on around the state.

"This initiative no doubt has the capacity to greatly enhance the environment and increase the State's revenue generation drive whilst reaping the benefits of business efficiency."

Flight of fancy

To be installed by Labor Day weekend, the carousel will include a resplendent assortment of local land, sea, and air creatures: lobsters, rabbits, owls, a skunk, squirrel, fox, right whale, sea turtle, cod, peregrine falcon, grasshopper, three species of butterflies, a sea serpent gondola, and a harbor seal chariot. According to the Rose Fitzgerald Greenway Conservancy, the animals were inspired by drawings from Boston schoolchildren, and the project, which also includes a new park, was funded by grants and several dozen donors.

Briggs, for his part, has spent the last three years dedicated to it, intensively researching the various creatures, then designing and sculpting them. PainterWilliam Rogers of Haverhill has worked to bring depth and dimension to what are essentially shaped canvases, painting each piece by hand and with airbrushes, and sometimes using sponging to create the illusion of fur.

"I had never really painted in three dimensions," Rogers, who specializes in backdrops, murals, and trompe l'oeil, said on a recent afternoon in his Haverhill workshop, rubbing his hand over the shell of a giant lobster. "To get these things that are ghost-white and give them life is really exhilarating."

Around him in the large former mill space, the figures were spread out in various stages of completion, all secured on their poles. Some were covered in plastic, others exposed and bare white; a few had sockets in need of eyes, while several were completed and seemingly prideful in their extravagant markings and colorings. The interior housing of the carousel, elaborately carved with butterflies, also took up one corner.

A total of 14 creatures will be spread out over three rows on the carousel; most will appear only once, while the butterflies, rabbit, lobster, and owl will be repeated. The 36-foot-diametercreation will be powered by an interior motor surrounded by the carved wood housing, and will also incorporate mirrors, an interactive sound system, and an led corn light display, Briggs explained.

"As it turns, you'll have this rhythm of light," he said from his seat on the seal chariot, as yet unpainted and with ponderous, reddish glass eyes.

The animals, with bodies of fiberglass and eyes of custom-made glass, are both lifelike and whimsical.

The gray squirrel bounds, tail curled over its body. The fox prances, head turned and ears pert. The barn owl spreads its wings in midflight. The bright blue right whale blows out a spout of water, baring its baleen and pink tongue, barnacles fixed on its snout.

Entwining itself with the gondola, meanwhile, is a lesser-known creature: A shiny silver, pink and, orange oarfish - the longest bony fish in the sea, growing up to 50 feet and resembling an enormous eel. Rarely seen, it was once deemed a sea serpent.

The colors used in the carousel are vibrant and purposely exaggerated; Rogers accentuated each animal's natural markings with shadowing and layering techniques and interference paint (which essentially changes color depending on the angle).

For instance, the lobster - tail lowered, claws clasped together - has its natural dark brown elements, but they're accented with subtle purple and green hues. The turtle's flippers shimmer with varying shades of purple, red, yellow, tan, and orange, while its shell features subtler strokes of brown, amber, crimson, and lavender. And the skunk, which seems a simple black and white, has hints of blue and violet.

"You can almost see the life in this thing," Rogers said.

Getting to an end product required hours of research - Rogers and Briggs relied on numerous photographs of each animal at different times of day (Rogers pointed out that even a plain gray squirrel looks different in sunlight than at dusk), investigating their color ranges, movements, habits, where they live, what they eat.

DTM introduces lighting system to avoid tyre usage confusion

17. května 2013 v 8:51 Led ceiling light
The DTM will use an onboard lighting system to show when cars are racing on option tyres at Brands Hatch this weekend in response to the confusion generated by the new rubber at Hockenheim.

The Formula 1-style option tyres were introduced at Hockenheim two weeks ago as part of a raft of technical changes aimed at spicing up the on-track action.

The option Hankooks were marked with a yellow stripe in order to allow spectators to see when a driver was using his one permitted set of the soft rubber during the race.

However, the stripe proved difficult to spot. With timing screens and television graphics also failing to display sufficient information, fans, commentators and even teams were unable to spot what many cars were using at any given time.

Series promoter the ITR has responded by using the orange lights mounted on the sides of each car - and previously used to show how many pitstops a driver had made - to display tyre usage.

The orange lights will come on when a car is on option tyres and will be turned off when it is using the harder, standard rubber.

ITR chairman Hans Werner Aufrecht said: "We have to involve and inform both the fans on-site and watching on TV much better. To them the races must be more clear.

"The race at Hockenheim made clear that identifying the yellow marks on the option tyres was virtually impossible. Consequently even our TV commentators had the problem of identifying what was going on.

"We are working in cooperation with [German motorsport federation] the DMSB and Hankook on ways to improve this, such as using the LED lights. We hope that this will be a significant step forward at Brands Hatch."

AUTOSPORT understands that the possibility of widening the yellow stripe on the options, so as to make it more visible, is also being evaluated.

And it wasn't just me either. Several TV commentators and numerous team managers were equally baffled. None of us were able to read the race properly, and were therefore in the dark as to whether driver X's pace at any particular stage of the race was option-influenced or not.

That's just us lot, who had the benefit of timing screens and the odd publicly-broadcast pit-to-car radio transmission. The fans sitting in the grandstand had none of that, and must have been even more confused.

Key to the cause of the problem was that the yellow stripes painted on the sidewalls of the options were simply not wide enough, and were impossible to see at speed; the tyres being of a far lower profile than those used in Formula 1, for example.

The use of side and front-mounted led par light is, for now, a trial. If it doesn't work, you can bet a different solution will be employed at Spielberg. They do have a habit of getting things right in the DTM, remember...

Rambus Broadens LED Portfolio

7. května 2013 v 7:51 LED downlight
Rambus Inc. recently came out with a host of light emitting diode (LED) bulbs thereby adding to its recently introduced LED portfolio. Its LED portfolio now includes the 65-watt PAR30 bulbs and the 75-watt BR30 bulbs.

Earlier this year, Rambus, better known for its technological inventions, introduced a technology-turned product, its first ever LED bulbs (60-watt A19 bulbs). The bulbs, which leverage its MicroLens optical technology, help generate consistent lighting and control spherical distribution of light. The company asserts that the bulbs are economical (due to lower production cost), energy efficient and long lasting.

The bulbs have improved features such as micro-electronics, dimmer capability, better lumen output (a measure of the total amount of visible light emitted by a source) and advanced thermal management capability.

Rambus' LED portfolio is ready to hit the market shortly, with the first shipment expected during the third quarter of fiscal 2013.

Along with the bulb invention, Rambus also set up a business alliance with the Elite Group for the promotion and sale of its bulbs across North America.

LED is a semiconductor light source used as indicator lamps in many technological devices and are increasingly being used for general lighting products. LEDs are energy efficient, long lasting, space saving but relatively more expensive than incandescent light sources.

However, the technology continues to evolve, with significant advancements in brightness of the LED devices that would make them all the more suitable for the lighting revolution. Hence, Rambus' entry into this growing LED lighting market could prove extremely beneficial going forward.

In Mar 2013, Rambus divested its Display patent assets to a subsidiary of Acacia Research Corporation to focus more on the LED space. Display patents were offered under the Lighting and Display Technologies segment. The divestiture was planned during Rambus' third quarter of 2012.

With the rising popularity of energy-efficient lighting, the in-vogue LED products are finding place in the latest architectural, retail, commercial and residential lighting fixtures. We find Rambus in a favorable position to capitalize on this opportunity.

With lower energy costs, better control, and the safety afforded by a rugged solid-state design with superior thermal management, the benefits of LED for all sorts of industrial, commercial and residential task lighting are hard to ignore. But what about floodlighting? Can a technology that began with tiny red lamps take on the challenge of lighting a broad area in harsh and hazardous conditions?

The answer is "yes." In fact, Appleton's new Areamaster LED luminaires are particularly well suited to the task. And it's not just because Appleton's LED technology provides the quality and distribution of light required for effective industrial floodlighting. Areamaster is also designed to substantially reduce the time and cost of installation and maintenance in the hard-to-reach locations where floodlights are usually placed.

At only 15.5" square, 4" deep and 22 lb. in weight, Areamaster LED luminaires are easier to install than many other types of floodlights, including competing LED models. Once installed, they provide reliable, high-quality light over a maintenance-free lifetime of 60,000 hours. The bronze polyester coated copperfree aluminum housing is designed to look great and protect internal components year after year, even in weather-exposed, corrosive and rugged environments. And when Areamaster LED floodlights do require maintenance, a one-piece housing and one-piece hinged lens and cover secured by four captive stainless steel screws makes access easy and safe.

Why Do Conservatives Like to Waste Energy?

3. května 2013 v 7:38 led par light
When the lights went off during Beyonce's halftime set at the last Superbowl, conservative commentators from the Drudge Report to Michelle Malkin pointed blame (erroneously) at new power-saving measures at New Orleans' Superdome. And one recent study found that giving Republican households feedback on their power use actually encourages them to use more energy.

Why do conservatives, who should have a natural inclination toward conservation, have a beef with energy efficiency? It could be tied to the political polarization of the climate change debate.

A study out Monday in the journal Proceedings of the National Academy of Sciences examined attitudes about energy efficiency in liberals and conservatives, and found that promoting energy-efficient products and services on the basis of their environmental benefits actually turned conservatives off from picking them. The researchers first quizzed participants on how much they value various benefits of energy efficiency, including reducing carbon emissions, reducing foreign oil dependence, and reducing how much consumers pay for energy; cutting emissions appealed to conservatives the least.

The study then presented participants with a real-world choice: With a fixed amount of money in their wallet, respondents had to "buy" either an old-school lightbulb or an efficient compact florescent bulb (CFL), the same kind Bachmann railed against.

Both bulbs were labeled with basic hard data on their energy use, but without a translation of that into climate pros and cons. When the bulbs cost the same, and even when the CFL cost more, conservatives and liberals were equally likely to buy the efficient bulb. But slap a message on the CFL's packaging that says "Protect the Environment," and "we saw a significant drop-off in more politically moderates and conservatives choosing that option," said study author Dena Gromet, a researcher at the University of Pennsylvania's Wharton School of Business…

Gromet said she never expected the green message to motivate conservatives, but was surprised to find that it could in fact repel them from making a purchase even while they found other aspects, like saving cash on their power bills, attractive. The reason, she thinks, is that given the political polarization of the climate change debate, environmental activism is so frowned upon by those on the right that they'll do anything to keep themselves distanced from it.

"When we're given an option where the choice is made to represent a value that we don't identify with or that our ideological group doesn't value," she said, "this can turn the purchase into something undesirable. By making [the environment] part of the choice, even though they might see the economic benefit, they no longer want to put their money toward that option."

Unlike conventional lighting systems where rated average life for a lamp is the point at which half the lamps fail, useful life for an LED is hard to estimate since catastrophic failure takes so long to occur. In fact, LED light sources continue to give light even after their initial lumen output has decreased by 50%.

To determine knowing how long an LED fixture will retain a considerable percentage of its initial luminosity, lumen maintenance measurements are used instead of meantime to failure measurements. The lumen maintenance specification for an LED is typically the time it takes for an LED to reach 70% of its illumination. This 30% reduction in light output is considered to be at the threshold for visually detecting a gradual reduction in light output.

A winner in the light bulb wars

2. května 2013 v 5:18 LED downlight
Light-emitting diodes (LED) -- the same technology that now provides the backlight for many flat panel TVs -- will see its use double in the next year. The technology will replace fluorescent tubes in commercial applications, help make more efficient street lights with less light pollution, and most importantly could look cool in the process.

According to NPD DisplaySearch's latest forecast, LED in lighting applications will double from 15 million units in 2012 to a forecasted 33 million in 2013. That number could triple by 2015. The global penetration for LED light applications will likely increase to 26% of the market, up from just 5% last year.

To date, Japan has been the largest market for LED lights, while China will soon drive the market due to government demands including the 12th Five-Year Plan. "The potential for China is there," says Philip Smallwood, lighting market analyst for IHS iSuppli. "But in the United States we have a lot of regulation also coming to into play."

This past January saw the switch flipped for the 75-watt incandescent light bulb, which followed the end of the line for the 100-watt as a result of the Energy Independence and Security Act of 2007. Next year will see the ban move to 60-watt bulbs as well. LED bulbs will likely fill this void. But they could also replace those curly compact fluorescent bulbs that now seem little more than stopgaps between incandescents and LEDs. "Compact fluorescent light bulbs are replacing incandescent bulbs, and LED bulbs are replacing the compact fluorescent light bulbs," explains Steven Sher, NPD DisplaySearch analyst for lighting technologies. There are currently no policies in place to phase out compact florescent light bulbs; however, there are many policies to phase out the incandescent bulbs.

However, what is true for the U.S., Europe, and even China won't necessarily follow for the developing world. While the price of LEDs continues to fall, these bulbs are still more expensive, and thus incandescents could prove popular in many parts of the world throughout the next decade. Moreover it will likely be the compact fluorescent bulbs -- even with the environmental concerns as the bulbs contain mercury -- which will outpace LED adoption in the developing world. "In the less-developed countries where they don't have the spending capacity that we have in North America they will likely stick to the CFLs," adds Smallwood.

Incandescents won't simply shut off even as the 2007 energy act continues to pull bulbs off store shelves. For one thing many consumers, anticipating the ban, bought up stocks of the old bulbs. "We don't change light bulbs in what could be called a proactive way," Smallwoods tells Fortune. "We change our bulbs in a very reactive way, when they burn out. With that in mind we'll be seeing CFL and even incandescent bulbs very much in use in the next five years - unless everyone runs out and buys new bulbs, and that isn't going to happen."

The technology has been slow in gaining traction. Many people might think of LED bulbs as something new, in fact this technology has been around for more than 100 years but only found commercial applications in the late 1960s as costs fell. It has taken the last 40-some years for the technology to be finally ready for the home.

Now thanks to lower costs and greater applications, LED could have people taking a new look at it. While CFLs were met with those aforementioned environmental concerns, they had other issues that kept the technology from being embraced. Although they offered energy savings, the high costs up front kept consumers buying incandescents, while detractors noted that the light from the CFLs tended not to be as soft as that of the beloved bulb that has lit up homes for more than 100 years.
