Wauwatosa Ask Now: Are the new lights going in LEDs?

Yes, the city of Wauwatosa is replacing all high-pressure sodium lights with the brighter, whiter lights that also light up a larger area, said Randy Michelz, traffic and electrical superintendent. The parkway also is getting the same type of lights. "We have been replacing these lights over the past two months as part of the infrastructure work that included the sewer project," Michelz said.

Camas begins replacing its streetlights with LEDs

The city of Camas kicked off a project this month to replace more than 3,000 streetlights with LED bulbs. The $3 million project will replace about 2,000 “cobra head” streetlights — the ones attached to an arm that hangs over streets — and about 1,100 “acorn” lights — the more decorative ones that typically sit on top of a pole — according to Steve Wall, Camas’ public works director, and add lights to Pacific Rim Boulevard. The cobra head lights are expected to be fully in place by mid-March, and the acorn lights, which are in more residential areas, will start switching over in late March or early April and continue through late spring or early summer.

Use This Type Of Light Bulb To Combat Hordes Of Insects This Summer

If you don’t want your home invaded this summer, you’ll want to learn the results of a summer-long experiment meant to test whether different light bulbs attract different amounts of bugs. It turns out that incandescent bulbs attract the most insects, while yellow-orange LEDs attract the least. Every night for an entire summer, Mike and Teresa Justice, two behavioural ecologists with PhDs from the University of North Carolina, Greenboro, set up a bug trap and turned on a single bulb inside. The type of bulb changed from night to night.

Osram's Novel Strategy To Gain In LED Lighting

Ten years is more than enough time. That is the idea underlying a new line of LED bulbs from Osram Sylvania designed to gain the company new customers and market share. Rather than produce bulbs for consumers that might last 25,000 to 20,000 hours (or about 20 years of ordinary use), the new bulbs are made from components that will effectively give the bulbs a more limited lifespan of around 11,000 hours. Trimming the life expectancy and other tweaks, however, enables Osram to drop the price of a 60 watt-equivalent A19 LED bulb to $3, lower than bulbs of comparable quality from competitors, said Alfred LaSpina, LED product group manager at Osram.

LEDs starting to light India

Just about a year ago, the Domestic Efficient Lighting Programme (DELP) was inaugurated by Prime Minister Narendra Modi. The aim was to replace all 770 million incandescent bulbs used in homes and 35 million streetlights with LEDs over three years. This, it was hoped, would result in a reduction of 20,000 MW load, energy savings of 105 billion KWh and greenhouse gas (GHG) emissions savings of 80 million tonnes every year. The annual saving in electricity bills of consumers, it was estimated, would be Rs 40,000 crore, considering an average tariff of Rs 4 per kWh.

$3 gets you an Osram LED light bulb that lasts for 10 years

Most LED bulbs last for about 20 years of average use, but a new approach from Osram Sylvania says that’s way more than we need. By cutting the life expectancy of its A19 LED bulb from the standard 20,000 or 25,000 hours to about 11,000 hours, Osram brings the price of its 60-watt equivalent bulb down to a $3 price tag. Hopefully, that will help even more people make the jump to LED technology.

A Beautifully Brutalist Desk Lamp

Admittedly, there’s not much that feels heroic about desktop drudgery. But this concrete lamp/planter combo could at least add a bit of architectural interest to your toils. The small lamp, which will be available this spring via Kikkerland, is powered by a USB cable. A fabric-wrapped cord is included; plug it into your laptop to shed a little light on your to-do list or reading material.

How long do LEDs really last?

I was contemplating my own mortality recently, when I realized 2015 passed by in a blur. Ruminating about the loss of yet one more year, I looked at my LED-laden lamp and thought, “Sure, you might last 50,000 hours, while my expiration date is virtually unknown.” But, was this true? Happy to take the thought process from my own shelf life to that of an LED, I began to wonder if that 50,000, 35,000, or 25,000 hours of use from an LED could possibly be accurate. For one thing, I don’t mark down the date of purchase for my LEDs. Do you?

Minute Maid Park in Houston Going with Musco LEDs

Minute Maid Park, the home of The Houston Astros baseball team, will have new LEDs from Musco Sports Lighting. The field will be using the company’s SportsCluster Green system, which is replacing the original metal halide equipment was installed in the stadium when it opened in 2000. The new lighting is expected to cut energy consumption by 52 percent.

The real reason for the LED push

Manufacturers of LEDs are pulling out all the stops and pushing their products to market with ever-increasing claims of greater efficiency, performance, lower cost, and more, but those aren’t the only reasons for the push. Recently GE Lighting announced that it will stop CFL bulb production by the end of 2016. According to GE, in 2015 incandescent bulbs represented 38% of the market, followed by halogen at 26%, CFLs at 15%, LEDs at 15%, and linear fluorescent at 6%.

Miniaturization of Electronic Devices to Boost the Global Chip on Board LED Market by 2020

Technavio analysts expect the global chip on board LED market to exceed USD 9 billion by 2020, growing at a CAGR of over 35%, according to their latest report.

Global chip on board LED market to exceed USD 9 billion by 2020, growing at a CAGR of over 35%.

The global chip on board (COB) led market is dependent on LED manufacturers as they are the principal customers of this technology. LED manufacturers, such as general lighting, backlighting, and automotive lighting manufacturers, use the COB LED packaging method during the back-end process of LED production.

The demand for compact electronic devices has grown in almost every sector, be it telecommunication devices, automotive, industrial manufacturing, or healthcare equipment.

This trend has compelled LED manufacturers to invest in R&D to reduce the size and increase the performance of LEDs, which has led to advances in LED chip technologies. COB LED technology directly attaches the LED chips in the form of arrays onto the substrates, thereby offering higher packing density compared to other traditional surface mount technologies. The higher packing density enhances the output of LEDs in terms of intensity and uniformity.

Mercury-based lighting solutions such as incandescent lamps are banned in most countries including the 28 countries of the European Union (EU), BRIC nations, US, and Japan due to environmental concerns. This ban has led to the adoption of energy-efficient light sources such as CFL, halogen, and LED lights in the market. These light sources consume less energy and have a longer life span than incandescent light sources.

LEDs are non-hazardous sources of lighting as they are devoid of ozone and mercury, save energy, and have other properties that enhance sustainability. Therefore, OEMs around the world are investing heavily in LED technology to reduce their power supply cost and adhere to these legislative changes. The phasing out of mercury-based lighting solutions will have a moderately high impact on general lighting LED manufacturers.

UD researchers examine combinations of lamps, dimmer switches for poultry houses

A problem growers run into when trying to decide which lamps to purchase is knowing what lamps (commonly referred to as bulbs) and dimmers (equipment that controls lamp light output and switches lamps on and off) work best together for their particular operation. Researchers developing health care technologies will receive a total of $600,000 in funding through the eighth round of the University City Science Center's QED Proof-of-Concept Program.

Infrared LEDs Boost Machine Vision, Day and Night

Where do you go for in-depth, insightful help in understanding and selecting IR LEDs for CCTV application requirements? The night has a thousand eyes; and so too, the day. Increasingly these watchful eyes are part of security cameras and other full-spectrum imaging and sensing systems where improved visibility has become a design mandate due to less-than-ideal lighting conditions. For these applications, designers are now integrating infrared LED components into their systems for the express purpose of secondary illumination.

Compact fluorescents are being shoved aside by LED bulbs

The twisted compact fluorescent light bulb has long been used as a design element to represent up-to-date technology, but at the rate things are going it will soon be representing out-of-date technology. “Right now, we’re still doing about half and half” of LED and non-LED bulb sales, said Crystal Murray, assistant manager at Lighting Place in Concord. Compact fluorescent and halogen bulbs make up the rest of sales, she said, but LEDs are growing. “About half of people who come in looking for bulbs are looking for an LED. . . . And if they pick up a fixture and we ask them if they need bulbs to go with it, they almost always choose the LEDs, even with the price point difference,” Murray said.

It’s a bird, it’s a plane, it’s an abstract lamp

I really love abstract design. Your own interpretation doesn’t just add meaning to the product, it also makes you connect with it on a level. That’s what emotional design is about. The My Bird lamp isn’t really a lamp, nor does it have a bird. Look close, however, and you may just see the bird. It also has a lighting element on the upper corner to justify it being called a lamp

LEDs brighten outlook at City Hall Maryville

Municipal government in Maryville has seen the light — or at least will very shortly after Clinton-based American Eagle Electrical finishes replacing fluorescent and incandescent tubes and bulbs with highly efficient LEDs in approximately 600 fixtures at City Hall, Maryville Public Safety headquarters, and the street maintenance garage. Installation by American Eagle owner David Stadter and subcontractor Karol Wilson began Monday and should be complete in two weeks or less.

UPS installs LEDs, going greener

First the campus grounds. Then the buildings. Then the power in the buildings. Now University of Puget Sound has gone “green” with the streetlights on campus, by installing low-energy, long-life LEDs (light-emitting diodes) throughout its grounds. Facilities services staff expect the change to the campus’s 62 streetlights will save an estimated 63,400 kilowatt-hours each year—enough to power five homes. Streetlights within the campus were switched from 250-watt high-pressure sodium lamps to 54-watt LEDs. The project, completed in January on the 97-acre campus, is one of many steps Puget Sound has taken to run its operations in a sustainable and environmentally friendly way.

Completing the switch from incandescent to LED

While walking by the Fisheries Supply booth at the Seattle Boat Show last week, I noticed their display of LED interior lights and thought, “Boy am I glad we finished that project.” That’s right, it’s done. This winter we finally completed the changeover of our interior lights from incandescent to LED. It took a while, but now that we’re fully running on brighter, less power-hungry lights, I feel like a great service has been done for our boat and for the occupants of its once excruciatingly cave-like interior.

Measuring and Preventing the Flicker of LEDs

Flicker behavior isn’t inherent to LED light itself. On the contrary, when running the LED on a DC power supply, without controlling its light output, it would not generate any flicker and give a nice and stable light output, says Steven Goetstouwers. However when building the LED light into a luminaire multiple levels of electronics are added, such as switching the AC power to a DC power and the use of Pulse Width Modulation to control the light output.

Legal marijuana an opportunity for LEDs

Jonathan Villagomez grew up maintaining his family's yard and tending to the church garden. At 19, he started a landscaping company before venturing off into the IT world. So when looking for business opportunities with LED lighting, it felt natural to intertwine the two. "I understand technology and how things connect, and I also understand how things grow and the nutrients they need," says Villagomez, a 28-year-old father of three.

A 52” long mounting plate constructed of 2” by 2” by ¼” thick carbon steel is attached to the upper section of the mast which provides a strong and stable platform for the four light fixtures. Each floodlight is securely fastened to the mast head with an innovative trunnion style stainless steel bracket that allows the light to be adjusted through 180° of vertical movement. These LED lights offer increased durability, longer lamp life, and lower power consumption when compared to the 1,000 watt metal halide equivalent. This LED light tower is equipped with forty feet of 16/3 chemical and abrasion resistant SOOW cord that is fitted with an industrial grade cord cap for easy connection to common outlets.

LED Projects Must Be Carefully Planned

Experts peg the changeover to LEDs as perhaps the most dramatic way to improve energy efficiency. It is the “killer app.” It therefore is no surprise that projects are announced on an almost daily basis. There extravagant claims about energy and cost savings, better quality light and longer operational life of the LEDs generally are true. These projects, however, are not the same and offer different levels of energy savings. Great care must be taken in optimizing each project.

ENO improves hammock comfort with integrated LEDs and mattresses

Hammock camping is far from a new phenomenon, but it's one that's gained some attention from the industry in recent years. Established brands and startups have been flooding the market with a variety of new designs, including flatter, more adjustable hanging beds like the Amok, more structured hammock-tent hybrids like those from Tentsile, bivy-hammock combos like the Alpine Hammock, and add-on shelter systems like the Nube.

Just place the magnetic mount on that surface and the Tack snaps into place. If you want to be hipster, you can also use Tack as a table lamp. Tack doesn’t judge!

Street lights of Corvallis take on brighter hue

There is a different tint to the skies above Corvallis. The city has been replacing its high pressure sodium (HPS) streetlights, which have given the city an orangish glow for decades, with brighter, whiter LED (light emitting diode) fixtures. City crews have been going block by block since 2014 and installing new lights on 780 poles owned by Pacific Power, said Adam Steele, franchise utility specialist.

This Weird LED Lamp Displays 3D Emojis

Every once in awhile, you come across a product that makes you wonder why no one has ever thought of doing it before. Today, however, I'm simply wondering, "Why?" Electronics maker Spin-R is launching an Indiegogo campaign for its $200 Tittle Light LED lamp (titillate, get it?). It's a modern-day strobe light that can tell others exactly how you're feeling via emojis.

Optogenetics uses LEDs to turn on potential cures

Targeting the treatment of chronic pain and other neurological disorders, the on-off switches of optogenetics are transforming neurosciences. So far used in lab animals such as mice, a wireless signal activates LEDs located near an animal’s spinal cord so that a blue light turns on genetically modified neurons, while a yellow light turns them off. This enables researchers to discover the brain paths involved in such conditions as obsessive-compulsive disorder (OCD) as well as depression.

Bright LEDs put growing number of Milwaukee storefronts in spotlight

For a growing number of small retail shops in Milwaukee, the guiding light is the LED. Cheap to operate — many places leave them on 24 hours a day — and flashy as an Elvis jumpsuit, the eye-catching lights are changing the streetscape along some commercial strips. Easily more than 100 businesses here have installed them, usually stringing them around borders of windows and doors. The owner of one sign and light company here claims to have fitted out more than 300 locations across the area.

Industrial coatings shop saves on energy with Independence LED tubes

Shop lighting consumes a significant amount of electricity for specialty manufacturing facilities. PAC had inefficient T12 fluorescent tubes running 9 hours per work day totaling 2,340h/year. The old tubes each used 187.2 kWh per year. At a $.12/kWh electricity rate, the T12 tubes cost $22.46 per year to operate. PAC had invested in a major rooftop solar system, so reducing the waste in the lights made strong economic sense. Independence LED provided energy savings of 62% over the existing fluorescents with new LED tubes and helped bring the facility to a “Net Zero” cost of lighting with the solar photovoltaic panels. This combination of solar on the roof and LED tubes in the ceiling serve as energy intelligent siblings.

GE is phasing out CFL bulbs so that LED can take off

Someday soon, your home will probably be lit by the glow of LED light bulbs. The transition is already taking place, but GE wants to see it happen even faster. It announced plans to phase out the sale of CFL bulbs in the US over the next year as it begins to position LED bulbs front and center. That means the next time an energy-conscious consumer goes looking for a light bulb from GE, they're going to pick LED.

Aootek LED desk lamp review

LEDs are working their way into everything – vehicle headlamps, flashlights, outdoor lighting, holiday decorations, kids toys, and our light sockets. With the advent of computers in offices over the past few decades, desktop task lighting has grown and expanded, so it’s only natural that the cool, low-energy, relaxing light of these devices should invade our workspaces. I was sent a portable task light from Aootek, billed as the “Rotary LED Light” on the bottom label. It folds up into a compact package for travel, charges with your phone charger or laptop, and is adjustable in output.

EpiTop Announces Record High Power DUV LEDs.

EpiTop Inc., a company in the development and manufacturing of deep ultraviolet light emitting diodes (DUV LEDs) announces that they have demonstrated high performance DUV LEDs with wavelength at 280nm from a single 4545 large chip device, achieved a world record optical output power of 176.6 miliwatt at 1A dc operation at room temperature. According to the best of their knowledge it is so far the highest reported optical power from a single die at such shorter wavelength under dc operation. The L-I and IV characteristic of the 4545 large chip was plotted below.

Yuanrong Technology Inc’s business has been extended from visible LEDs into DUV LEDs area since acquisition of QD Jason Electrical Ltd on October 2015, who was a sole DUV LEDs manufacturer in China so far.

“The new world record high optical output power was realized by using our proprietary homemade MOCVD technology and improved fabrication and packaging approach,” said Bob Liang, president of EpiTop Technology “the device voltage is as low as 5.8V even at 1A with differential resistance of 1 ohm only, such great electrical performance allows the large chip driven up to 1 A under dc operation before saturation, a contribution to the high output power achievement.”

Elgato Avea Flare Portable Mood Lamp

The Elgato Avea Flare Portable Mood Lamp is yet another new smart light that doesn't need a hub to work. What sets is apart from the competition?

Eco-friendly LED lamp brightens without batteries or plugs

LED lighting has widespread appeal due to energy-efficient output and low cost of manufacturing. Companies are now adding features such as sensors, wireless connectivity, adjustable color, or even built-in speakers into the mix, but this LED lamp takes a different approach by removing a critical component. The Lumir C is designed without any external power supply, instead operating off of a single candle.

Why LED lighting is so important to the chip market

The incandescent light bulb will soon no longer be the go-to choice for lighting. It has been a long time coming, but the cost structures normally associated with LED equivalents have dropped dramatically over the past 5 years or so, writes Tony Armstrong. It should be noted that the general LED lighting market represents around 57% of the total LED market of $25.9bn projected for 2018. The others being signage, automotive lighting, mobile devices, backlighting in displays, monitors and other.
