New trends at Lightfair 2012: Fine motion control and incandescent-like dimming

Středa, Květen 23rd, 2012

At Lightfair 2012, Lighting Science Group (LSG) demonstrated how the company is integrating controls and LED products across its product lines. “We’re taking controls and intelligence packages and wrapping LED products around them,” said Jim Haworth, chairman and CEO of LSG. One example of this combination is the company’s recently launched Forefront LED luminaires, available in area, flood, high bay, pedestrian and wall-mount versions, which can be controlled using PixelView occupancy sensing and video processing.

In a demonstration at Lightfair, David Henderson, chief development officer of LSG, showed how PixelView camera-based motion sensing can be programmed to sense disturbances in a specific area. “In the past, we used passive infrared, but what you find in different applications and in very cold or very hot climates, you can get dead zones where performance drops off,” said Henderson. Instead, PixelView uses a CMOS camera, similar to that used in automotive applications, and the motion detection can be confined to any part of the camera’s field of view. For instance, if the user wishes to program the camera to ignore a heavily trafficked area and instead focus on an area around a car, PixelView can be programmed to do that.

Each Forefront LED product is designed as a one-for-one replacement of 100-750W HID fixtures, requiring 50% less energy usage. The flood luminaire features lumen output up to 23,000 lm, and can be used for facade, sign, landscaping or architectural lighting.

Also at Lightfair, LSG recently introduced its RoadMaster LED street light, which is designed to be a low-cost replacement for HPS fixtures. Approximately 4000 100-150W HPS fixtures are currently being replaced in Puerto Rico.

Lighting Science Group is also preparing to roll out a solar-powered street light that will be capable of 3-day autonomy. Named FreeLED, the luminaire will contain all power electronics in one unit and will use a next-generation lithium iron phosphate (LiFePO4) battery, which offers better thermal and chemical stability than other lithium-based batteries. According to Lighting Science Group, the LEDs used in this luminaire have an efficacy of 133 lm/W.

Both Osram Sylvania and Juno Lighting introduced LED lamps capable of incandescent-like dimming at Lightfair 2012 to serve the needs of residential and hospitality environments.

Sylvania has released its Ultra PAR38 with CCT dimming, which allows dimming from 3000K to 2000K by using a combination of blue phosphor-converted LEDs and amber LEDs, according to Ellen Sizemore, product marketing manager for Osram Sylvania. She stated that if this incandescent-like dimming proves popular, Sylvania will make the dimming available on all its product lines.

Juno Lighting’s Chris Walsh, vice president of product management, explained that the company’s WarmDim recessed downlight received Lightfair’s Technical Innovation Award for the most forward-thinking advancement in LED lighting. WarmDim uses an on-board microprocessor to dim from 3000K to 2000K and is available on 4, 5 and 6-in downlights. The 600-lm downlight uses 14W of power. The downlights are available in retrofit or new installation versions.

Taiwan partners with Government to shed new light on renewable energy

Středa, Květen 2nd, 2012

The Government’s efforts at promoting renewable energy in the Federation today received a boost in a brief handing over ceremony held at the Embassy of the Republic of China.

Minister of Public Utilities Hon. Earl Asim Martin was on hand to receive a cheque to fund a pilot project that would see the installation of 100 LED Smart Lights along the Kim Collins Highway and a portion of the Frigate Bay Road.

In giving brief remarks, Head of Taiwanese Mission in St. Kitts and Nevis His Excellency Ambassador Miguel Tsao said as no country can stay away from the tide of the world’s development, Taiwan is happy to share the competitive edge in the development of renewable energy.

“According to preliminary studies from specialists in renewable energy” said Ambassador Tsao, “this kind of light can produce 70% savings of energy and last quite a long time. All the street lights are computerized and each light can be intensified according to the need of the respective area and time.”

The Ambassador also added that although relatively small, there is great benefit to be derived from this pilot project as it is a stepping stone to protecting the environment and leaving a better Federation for our children. The move supports Government’s energy policy of achieving 60% energy generation from green energy sources.

Minister Asim Martin, in accepting the cheque, expressed his thanks to the Ambassador and people of the Republic of China for their understanding in working with the Government of St. Kitts and Nevis to implement the Government’s overall policy on renewable energy.

“We expect that this project will start very shortly, the completion date we expect to be some time in maybe mid to the end of August” said Minister Martin, “so we are looking at between May and August having the Kim Collins highway right up to the Sugars building being lit with LED street lights.”

Minister Martin also said that he has been assured that once this pilot project is successful, similar projects will be implemented in other areas around the country.

The assistant football coach then shared that he believes the Bible says homosexuality is a sin. He added, however, “No matter which way you go, it’s going to be an unprotection [sic] because it’s man’s opinion. So the real question I guess I have for you all is – what does God say?”

Brown added, “The question I have for you all is, like Pontius Pilate, what are you going to do with Jesus? Ultimately, if you don’t have a relationship with him, and you don’t really have a Bible-believing mentality, really, anything goes… At the end of the day it matters what God thinks most.

Scuba diving attracts seekers of adventure

Pondělí, Srpen 15th, 2011

Hyde Park resident James Curran was introduced to scuba diving through an invitation to join a planned diving trip to the Maldives, near India.

He enthusiastically made the investment to buy his own equipment right away, partly to increase his commitment.

“Some people thought it was weird that a totally inexperienced person like me would spend all this money — what if I hated it?” he said.

Luckily, he fell in love with the sport. In less than three years, he has already logged 167 dives. Other destinations have included Belize, Aruba, the Florida Keys and Turks and Caicos.

This much activity is impressive for anyone, but take note: Curran took his first dive at age 60.

“People used to think of scuba as an extreme sport, but now it’s a mainstream, lifelong sport that we can do well into the retirement years,” said Andy Viviano, owner of Marsh Scuba, a City of Poughkeepsie dive shop and training center.

Tony Olheiser, owner of Dutchess Diving Center, another full-service Poughkeepsie dive shop, said diving is for people who want experiences, not just entertainment. “Perhaps they are inspired by shows on nature channels, but divers are people who are not looking to just take class; they want to experience the underwater world.

Diving gives the opportunity to travel through the world and see fantastic sights and have more fantastic experiences than you can imagine — better than anything you can see on the tube,” Olheiser said.

Also, one does not need to be an athlete to participate.

Town of Poughkeepsie resident Patty Mensler, 52, is a student and customer of Marsh Scuba. She has been trained in basic and advanced open-water LED diving flashlingt, underwater sign language, wreck diving and advanced buoyancy, among other skills. Mensler describes herself as being not a strong swimmer, which may surprise those who think swimming skills are required for divers.
