Officials warn businesses near beach about lights during sea turtle nesting season

Officials warn businesses near beach about lights during sea turtle nesting season

It’s turtle nesting season and officials in Martin County are concerned.

They are so concerned they sent a letter to representatives at the Publix Supermarket at 900 North Ocean Blvd. on Hutchinson Island in Stuart letting them know the parking lot lights can be seen from the beach.

County officials released a survey pointing out just how far those lights can reach.

Robert Ernest, the chief operating officer with the Ecological Associates Inc. said that’s a problem primarily for the hatchlings because when they leave from the nest they are orienting to the brightest horizon.

“And typically on a dark beach that’s the light reflecting off the ocean so they know how to get to the ocean, and when you have lights that are landward of the nest that can confuse them and draw them in the wrong direction,” Ernest said.

The letter states Publix should lower, reposition or shield the lights so they can’t be visible on the beach.

WPBF 25 News reached out to Publix officials, who issued a statement that reads:

“We haven’t received any official notice of violation. We did install light blinders at this store location and are in the process of permitting for new lighting fixtures as the ones currently in use are rusted. We are also working with the Florida Oceanographic Institute for the best lighting approach.”

County officials say they will also be sending letters to a local condominium and resident also found out to be in violation.

Publix has 90 days to adjust the lights.

LG Innotek and Daintree Launch the Standards-Based Wireless LED Driver

LG Innotek and Daintree Launch the Standards-Based Wireless LED Driver.

Networked LEDs are becoming more and more common in the commercial building space. But almost all of these LEDs are wirelessly connected through retrofits, using proprietary networks that can’t communicate with one another.

On Tuesday, South Korea’s LG Innotek announced that it’s breaking this pattern, with the launch of an LED driver that comes embedded with standard ZigBee wireless. Its partner, Silicon Valley startup Daintree Networks, has been working with LG on ZigBee-embedded LED light bulbs since last year. But this week marks the partners’ first foray into a wireless-embedded product for the troffers and retrofit kits that can replace standard overhead fluorescent lights with far more efficient and controllable LED equivalents.

“This is the first open-standard, ready-for-purchase solution for the mass market” in the LED driver space, according to Daintree CEO Danny Yu. LG Innotek’s new driver is using a defined standard — specifically, ZigBee Pro, which is being rolled into an umbrella standard known as ZigBee 3.0.

“The biggest advantage of using this driver is cost savings,” said Shin Cho, senior development engineer at LG Innotek. “Integrated drivers can eliminate the need for additional or extra wireless, or wiring.” That could make the company’s new wireless-integrated LED drivers attractive to the unnamed “major fixture manufacturers” interested in the new product, as well as smaller lighting fixture makers looking for a simpler route to wireless connectivity, he said.

Daintree and LG aren’t the only companies integrating LEDs and wireless controls in commercial ceilings, of course. Boston-based startup Digital Lumens has deployed its LEDs into 100 million square feet of commercial real estate, much of it warehouses. Redwood Systems (bought by CommScope) and Adura (bought by Acuity) have both installed their networked LED lighting systems into millions of square feet of commercial buildings as well.

LG Innotek’s new driver is built not with a Daintree chipset inside it, but with a standard ZigBee chipset, designed and built by LG based on the firmware designs that Daintree has made available to partners since 2012. That means that, theoretically at least, any other provider of an “enterprise-class, multi-function network control platform” adapted for ZigBee could make use of the drivers in lieu of Daintree’s ControlScope platform, Yu said.

For LG Innotek, this standardization has meant a much faster path to market, Cho noted.

“With Daintree, we didn’t need to modify anything — we just adopted that, and we went through the certification process easily,” he said. That, in turn, allowed LG Innotek to “minimize [the] resources dedicated to software development. We can spend more time focusing on developing and improving the hardware.”

The overall benefits equated to cutting product development time in half, and reducing total bill of materials cost by 10 percent to 20 percent, Cho estimated.

Of course, there are reasons why other vendors have made tweaks to standard ZigBee in their lighting networks. The low-power wireless technology can sometimes struggle to scale up to the hundreds of endpoints that it needs to support in lighting applications. “There is no perfect standard,” Yu said about this issue. “We are aware of the potential limitations of the ZigBee standard — but we are there to solve those problems.”

There are also reasons to architect a wireless lighting control system in ways that require a non-standard solution. San Francisco-based startup Enlighted, for example, has built distributed intelligence into its smart lighting nodes, giving them the ability to follow schedules and automated response patterns in ways that systems reliant on constant network connectivity might not be able to match.

Proprietary networks could gain ground simply through the weight of their incumbency in the market. Big lighting vendors like Cree and Philips have built their own proprietary wireless mesh-embedded LED control platforms.

Meanwhile, other contenders for low-power wireless standards in networked lighting are emerging, such as the Thread standard, an IPv6 networking protocol built on the same IEEE 802.15.4 standard that underlies ZigBee, launched by Google’s Nest Labs and Samsung last year.

But Daintree and LG Innotek are betting that their standards-based approach, combined with the current market penetration of ZigBee, will offer lighting system manufacturers a more compelling path toward future interoperability. That doesn’t just apply to the lighting environment, but to broader building networks, Yu noted. Like most of the networked lighting companies out there, Daintree and its partners are hoping to expand their in-ceiling wireless nodes to connect thermostats and sensors, and serve as the glue for broader energy management systems.

“Some of our products, like networked sensors, occupancy sensors and networked cameras, can be connected to this kind of system as well,” Cho said. “Our first approach is to develop and launch available product, which has cost-effectiveness” — and LEDs, which offer much greater efficiency, lifespan and light-by-light control features than the fluorescent lights they replace, have that characteristic, he said.

“After that, we will try to expand our types of products, like sensors and cameras, and [will also be] adding more features.”

LED industrial lighting market to reach US$2.366 billion in 2015!

LED industrial lighting market to reach US$2.366 billion in 2015!

LED light bulbs!

The LED industrial lighting market scale will be worth US$2.366 billion in 2015, and by 2018 will reach US$3.935 billion, according to findings from LEDinside.

Compared with home lighting products, industrial lighting products operate for longer periods, so switching to the energy-saving LED technology is more cost-effective. As a result, LED high and low bay lighting fixtures have become more attractive for industrial lighting users for replacement purposes. Furthermore, LED lighting products have seen additional increases in performance and decreases in pricing. These improvements, together with industrial lighting products’ high profit margins, have made industrial applications the most competitive market for LED package and LED luminaire companies for the 2015-2016 period, the firm said.

Among different fixture types, LED high/low bay lighting products are the largest in terms of market share. This category is further subdivided into mining and general applications (or for use in warehouses, gyms, and other indoor settings), making LED high/low bay lights a major focus in the development of industrial lighting market.

LEDinside expects 80W-250W LED high/low bay light products will become the mainstream in the market as improvements are made to the LED technology and to thermal dissipation. Current 80W-250W LED high/low bay lights have around 10,000lm-30,000lm in terms of luminous flux as well as 275-300lx in terms of illuminance. Pricing strategies for high/low bay lights vary according to product lines and market regions as these products have yet to be standardized. China-based makers tend to have lower product prices and fewer product lines. Hence, prices in the China market are expected to only show minor price fluctuations, the firm added.

Leaders in LED industrial lighting include GE Lighting, Cree, and Cooper Lighting, as well as their Japan counterparts IWASAKI and Toshiba, and China LED maker Ocean’s King Lighting. Among these competitors, CREE has made advances with high-power LEDs that save costs and simplify product designs. GE Lighting by contrast focuses on LED module adoption and thermal dissipation design. Their luminaires can have a life of up to 100,000 hours.
