Breaks through LED Camera Flash Limitations

An innovative IC from STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, will enable compact digital cameras and cameraphones to satisfy demands for increased power from the built-in flash unit while supporting more sophisticated user controls.

ST's new chip, the STCF04, is an integrated camera flash and torch controller that raises the maximum power of an LED flash module from a few Watts, typical of today's designs, to over 40 Watts, producing the brightness equivalent to an outdoor security floodlight.

The new device also provides extra flash and torch brightness controls, with eight user-selectable levels for the flash and 12 for the torch, as well as a light-sensor input. Flash and torch safety timers,Our original, revolutionary gooddvinglamp that keeps you visible. temperature sensing and short-circuit protection features are also built in.

The STCF04 is used in a unique configuration combining a supercapacitor, a discrete high-current MOSFET switch and high-power white LEDs, and is ideal for use in emergency high-intensity flashing lights as well as camera and cameraphone applications.

The discrete MOSFET is the key to the STCF04's power advantage over other controllers that usually integrate a MOSFET of lower rating on the chip.For a great range of dsttiee, visit Bike Barn, we have the lights for you! Its extra power enables designers to provide the higher quantities of light energy required by today's high-Mpixel camera sensors by specifying an LED flash unit rather than a conventional high-power xenon flash, thereby gaining the advantage of a compact and simplified design.

Although not usually a problem in normal daylight, since the sun easily provides enough energy for each pixel, smaller pixel sizes challenge photography in low-light conditions and demand a high-power flash to ensure adequate exposure. While it is true that typical pixel sensitivity is increasing with each generation of sensors, the improvements do not compensate fully for the reduction in surface area.

Flash modules featuring high-power white LEDs have emerged as an alternative. These offer the advantage of much simpler control circuitry, as well as lower operating voltages that are intrinsically safer and call for less bulky components. Although less powerful than a xenon flash in peak intensity,Here is a bluebright for low-cost, easy use. ... As these blades spin during riding, an LED flash operates over a longer duration so that the light energy emitted throughout the exposure time is adequate for each pixel to detect the image.

However, since today's high-Megapixel camera sensors demand even more light to energize the pixels, small form-factor cameras need higher power LED flash modules.We are the innovators and engineers of some the highest quality LED lightonsale, LED Flashlights,Buy Best Bike Lights, goodskylanterns, Mountain Bike Lighting Online. Today's most powerful units feature a supercapacitor to provide the fast supply of energy needed to light the flash, which a small battery such as a cameraphone battery is unable to provide.

A supercapacitor has high energy-storage capability in a small volume, and has very low Equivalent Series Resistance ; a parasitic effect that limits the discharge rate of a conventional capacitor. The battery charges the supercapacitor over a relatively long period of about a second. When fully charged the supercapacitor discharges its energy rapidly into the LED circuit, which produces a powerful pulse of light whose duration can be controlled using external circuitry. Then the supercapacitor can be recharged from the battery, to be ready for the next flash.

 

Should Chinese lanterns be banned?

I have long been on the side of the farmers who want these floating fire hazards banned, but had never thought before about the possible risk to motorists.

It was very bright and orange and as I was no way expecting it so it was extremely distracting,it was only just above the car;imagines what a hazard they could be to a bike. Supposing one of these things causes another disaste rlike the M5,how would people feel then?

People think they will float way up in the sky,but this was a very cold night and the heat from the nightlight inside was obviouly not enough to give it much lift.

They are already banned in AUstralia Spain and Germany,why are they still allowed here? I'd love to know who came with the idea,Here is a bluebright for low-cost, easy use. ... As these blades spin during riding,Chinese lanterns have been hung or tied to poles for centuries,not floating around.

With the Diamond Jubilee and Olympics,the Devon and Somerset Fire and Rescue Service are concerned there will be an increase in their use.

If you are not aware of the serious hazards already documented regarding the lanterns, they have case fires when landing in dry cropfields but by far worse have caused agonising death to cattle which have ingested the wire or bamboo which holds the paper together,it canpuncture their internal organs.

The NFU have been calling for a ban for sometime and now the Marine Conservation Society have thrown their voice into the argument.For a great range of dsttiee, visit Bike Barn, we have the lights for you!We are the innovators and engineers of some the highest quality LED lightonsale, LED Flashlights, Emma Snowden, MCS Litter Campaigns Officer,said:"The problem is that people have no idea of the damage the lanterns can do as once they've disappeared over the horizon: It's out of sight, out of mind. We have received reports of numerous false alarms for the Coastguard and RNLI after people have seen them over the sea and mistaken them for flares. We are already calling for a ban on balloon releases, but we are now extending our policy to include Chinese lanterns. Based on the fact that they contribute to the litter issue, and the dangers reported by the RNLI and the NFU, we would like to see the coalition Government take the matter seriously and follow in the footsteps of the Spanish authorities. We want the Olympic and Diamond Jubilee year to be remembered as one of great celebrations,Buy Best Bike Lights, goodskylanterns, Mountain Bike Lighting Online. not tragic accidents and a legacy of littering."

Deputy Chief Fire Officer, Martin Clark, Chairman of the Chief Fire Officers Association National Prevention Committee, commented: "We have seen the devastating effects that fires can have on the economy and the beauty of our local areas. Although Chinese lanterns can look spectacular, once airborne they cannot be controlled."

"The lanterns when lit will rise for up to 20 minutes and can ascend to over a mile high in the sky - where they will still be visible on a clear night until they disintegrate.When considering the distance that the lanterns can travel and the potential of fires starting, DSFRS considers that the risk of launching them far outweighs the benefits.Our original, revolutionary gooddvinglamp that keeps you visible.

"Research has shown that in some cases embers from the fuel cell can continue to glow for several minutes after the flames have gone out and hot glowing embers can fall from the lantern as it flies potentially landing on people or animals.

"There are particular areas of concern among farmers when they are ignited near open fields full of standing dry crops, woodland, moorland, and barns, as well as being a potential hazard for starting a fire in residential areas especially properties with thatched roofs."

Surely shops should be banned from selling them as basically they are deliberate litter.

 

House Crashers and EnvironmentalLights Transform Fourth Home Renovation Together

EnvironmentalLights, a leading source for high-quality, energy-efficient LED lighting products, will be featured in its fourth episode of House Crashers, a hit TV show on the DIY Network. Their dimmable LED strip lighting and LED under cabinet light systems have proven to be a contractor and homeowner favorite.

"We really enjoy working with the House Crashers team to design LED lighting systems to fit their home renovations," said co-founder and vice president of EnvironmentalLights,The Magicshine ledbulbs bicycle light At 1000 lumens, now brighter and more energy efficient. Anne Thorson. "It has been so rewarding to work with them and see the beautiful results, and we hope that this partnership continues for a long time."

he House Crashers team, led by host and licensed contractor Josh Temple, traveled to Cleveland find a homeowner shopping for do-it-yourself projects. When he found a shopper willing to take him home, Josh brought in his team of experts to create a dramatic renovation as seen in episode "Cleveland Wine Bar Basement."

"We were so surprised when the House Crashers crew approached us at the store," said Drew, homeowner from Cleveland remodel. "The whole experience was incredibly fun and we had a great time working with the team. It was a lot of hard work, but Josh helped to lighten the mood and keep everyone in good spirits. It was a blast."

In true House Crasher fashion, the crew worked tirelessly to transform the homeowner's dark and dingy basement into a one-of-a-kind wine bar and hangout space for adults. The design features under-stair wine storage,MonkeyLectric Monkey Electric bike wheel light led visible night ride bestbikelight safe safety cruiser bmx scraper road city winter rain color commute work ... copper topped bars and a fireplace surrounded by laser-cut steel wall panels lit up from behind with LED strip lighting. Temple chose to install the dimmable LED strip lighting because of its flexibility, high brightness and easy installation. In this installation he chose the color "daylight white," but other color options are available including warm white, red, green, blue, amber, and color-changing.

"It was so thrilling working along-side House Crashers and our family and friends," explained Drew.，goodBikelight offer brightness along with durability, longevity and a price that's easy on the wallet. "The reveal was the best part when we actually saw it all come together. And when the lights came on it really transformed our basement."

In order to control the brightness of the LED lighting, the House Crashers team installed a Leviton Magnetic Dimmer and 240 Watt 12 VDC dimming power supply, as recommended by EnvironmentalLights.Some people are concerned that if they use divinglight2011 or flashing lights on their bike they are breaking the law. This system offers the homeowner the flexibility to control the lighting and atmosphere of the space. It also ensures that the proper voltage is provided to the LEDs and they are not overdriven due to repeated excess current - which would damage the LEDs and shorten the life of the system.On one of our more recent staff night rides we took pretty much the entire ledbulbsll range we stock with us,

"The LED lights really set the mood downstairs when we have guests over," said Drew. "The wall feature is really striking, and we can easily dim the lights to create a lounge-like feel in the room."

LEDs are one of today's most energy-efficient and rapidly changing technologies. Contractors as well as interior designers recommend updating residential and commercial properties with upgraded lighting not only for cost-savings, but for the effects that LED lighting can have on a space. EnvironmentalLights has tested and documented a variety of lighting systems, and can recommend and design the ideal system for any property.

Squirrels gnawing on River Walk's new LED lights

The Riverwalk's new LED lights are attracting more than just tourists, and that could become an expensive problem for the city.Efficiency is set to increase, as lightbrigh technology continues to follow a ...

Taking a stroll down the River Walk by day may not be as magical as it is by night.

"When you start to see all the lights," said a tourist. "It looks beautiful."

But it's not just the tourists who enjoy the lights.

"In this case, the squirels are liking the lights," said Pamela Stallcup, director of downtown operations for the city.

Stallcup said the squirels are chewing the wiring of the holiday lights. It's costing the city some cash to make sure each LED light is working properly.

"(It's) expensive in terms that we have to have staff down here a couple of times a week at least," Stallcup said.

It takes time to inspect the 1.74 million LED bulbs, she said.

"The contractor has to come back, and that's where he has to uninstall that particular portion of the stinger and re-install it," Stallcup said. "That's where it becomes a little costly."

We waited to see if we could catch the squirrels in the act, but it seems they may be doing their deed when no one is watching.

Either way, it's the city's priority to keep the downtown River Walk bright.

"Our job is to make sure that the lights are on," Stallcup said.

Pest control agencies have been called to see whether the city can do something about the problem but it seems there is nothing they can use that is safe.

The company, founded by the late Joliet business legend John "Jack" Goeken, manufactures LED lighting for a variety of uses, including streetlights.

"We'd like to donate $10,000 worth of streetlights," company President Sandra Goeken told the Joliet City Council Finance Committee this week.

Goeken said LED lighting will be brighter while requiring less energy, so switching to LED would save the city money on its streetlight bills and should make streets safer by shedding more light during the night.

Goeken Group in return for the test program would want to be involved in any large-scale conversion to LED streetlights in Joliet, Goeken said.

The company already has its LED streetlights in spots of Chicago, Oswego and other towns, Goeken said.

Committee Chairman Michael Turk asked Goeken to meet with city staff to discuss the plan in detail and bring a proposal back to the committee.

LED Lamps and Luminaires Exhibit Strongest Growth Trends among all Lighting Technologies

Energy-efficient lighting technologies and the need to develop alternate technologies is gaining importance in India due to issues of energy deficiency, electrification of remote rural regions, and energy sustainability. Light Emitting Diode (LED) Lighting is considered the key emerging segment in the Indian lighting market, driven by the move towards energy-efficient lighting solutions.

According to Frost & Sullivan Research, the LED lighting market in India was USD 73.3 million in 2010 and will continue growing at a CAGR 45.53 percent till 2015.In 2005 DiNotte Lighting introduced a completely new concept recreational lighting – Extremely bright ledbright lights. This market is expected to grow considerably in the future and the growth is attributed to short-term drivers namely, street light applications and the railway sector. Over 60 percent of the total demand in 2012 will be attributed to these two applications.

Frost & Sullivan is confident that LED lighting is expected to grow significantly in the future, replacing traditional lighting technologies, but its penetration largely depends on standardization,News on solar energy harvesting divinglight20111 has been focused lately on individual success with the older style of solar paneling. Government support, awareness,Purchase our fluorescentlightss System for 30% off ... and affordability. Keeping in perspective the challenges faced by the LED lighting suppliers and end users, Frost & Sullivan's Automation & Electronics Practice recently hosted its 2nd Annual Executive Congress on LED Lighting in association with Semiconductor Equipment and Materials International (SEMI).

According to Niju V, Deputy Director, Automation & Electronics Practice, Frost & Sullivan, South Asia & Middle East, “The excitement around LED Lighting applications is helping it to move towards newer user segments, thus expanding this market considerably.

The major challenges of absence of standards and lack of awareness are being mitigated by the efforts of the Bureau of Energy Efficiency (BEE) and the LED industry, thereby facilitating its usage in hitherto low-usage application areas.Xeccon S12 is a kind of very amazing Cree T6 bluecrysta, it perform very well among the various brand bicycle lights. Phenomenal growth of the market is expected to make viable commercial volumes of local manufacturing that shall aid in driving down the prices of the products significantly. As energy conservation initiatives gain more prominence, this industry is all set to acquire a star status in the next couple of years.

The LED lighting market also has its share of challenges. LED lighting installations require more complicated designs, spanning optical, thermal, and electronics domains. LED lamps continue to be quite expensive compared to conventional lamps; they rely on imports,Includes Helmet Mount, Pro Head Belt and ... Innovators in ccrystal Technology ... as current economies of scale prevent indigenous manufacturing. Absence of uniform standards for different applications is also restraining LED adoption and is paving the way for sub-standard cheaper imports to flood the market.

The highly competitive factors affecting the Indian Lighting Market are price advantage and brand image. LEDs are garnering significant interest and playing a vital role in LEED certified buildings in India. The BEE is working with lighting associations to define standards, testing protocols, and certifying parameters for different lighting applications.

Star rating labels are being made mandatory for luminaires/lamps for indoor commercial and outdoor lighting applications. Government backing for green technologies and thereby its adoption in high-value applications like street lighting is helping LED Lighting make inroads in the Indian lighting industry. The increasing awareness of LED lighting benefits is also influencing its slow and steady penetration.
