LED streetlighting: the Light at Night Falls Bright

Welland, Ontario has launched the first phase of its LED lighting scheme and has installed 47 luminaires from Relume, writes Brian Owen. By George, theyve got it! Much like the alliteration from My Fair Lady, LED has evolved from its rough edges of past And arrived as a Lady in diamonds in the City of Welland, Ontario, Canada. On Tuesday, December 5th, the City launched the first phase of its LED outdoor lighting installations through the unveiling of a pilot on Fitch Street. Maybe not by George, But definitely by Peter; Peter Hochstein that is of Relume Technologies of Oxford. Michigan, USA. Relume was awarded the first phase of the contract which called for the supply of LED lighting in a roadway application.
As darkness fell on the streets of Welland, Peter Hochstein (second from right in the photo) joined Welland Mayor Damian Goulbourne, Peter Love, Ontarios Chief Energy Conservation Officer and Tim Clutterbuck, Chair of the Well and Hydro-Electric System Corp. under the well -lit cool white daylight appearance created by the Relume LED luminaires, which illuminated the street.
A total of 47 luminaires line the street, spanning 2 linear kilometers and encompassing over 300 residences, high rise apartments, 2 schools and a community shopping centre. while a number of pedestrian street lighting applications are in the pilot stage, such as in Torraca, Italy and Ann Arbor, Michigan, USA, this is the first LED outdoor lighting application to be installed on a full street in a roadway application in Canada and North America.
Relume comes to the street with years of experience in LED technology and commercial signage and now in general illumination in outdoor lighting. An important focus of our current research is the development of full cut-off LED lamp fixtures that are Dark Sky compliant, stated Peter Hochstein, adding, In the near future, we will have LED lamps with programmable intensity controls and some will have a two colour feature to further the light pollution and permit astronomical observation.
The design of the Relume roadway product is modeled on the traditional cobra head luminaire. Hochstein also commented that, We [Relume] are currently working with other municipalities in Canada and the US to relamp entire metropolitan areas with our LED cobra heads and decorative street lamps As the regulation of operating temperature is an integral part of luminaire development, Hochstein also noted that, Relume is one of the leaders in this science and has the installations to validate that claim.
The Relume luminaires utilized 90 watts of power compared to the 175 watts used by high-pressure sodium lamps being replaced.
"Focusing on projects that enhance the environment while ensuring responsible use of taxpayers' dollars is just one way the City is working towards achieving its strategic goals and objectives. The Welling's Mayor, Damian Goulbourne, is encouraged by the changes he is seeing in Welland. Installation of LED streetlights on Fitch Street is a good example of such projects. We look forward to getting as much feedback as possible from our citizens about the new streetlights by accessing the online survey or by fails calling City Hall."
Public education and awareness
An important part of this process is that Welland is keen to learn what the public thinks of the new lighting and has contracted greenTbiz, an energy efficiency and environmental practices program, to undertake a public consultation and perception analysis that will gather comments and public opinion through Door-to-door and online surveys.
This is fundamentally in the public education and awareness process and will directly result in the gathering of pertinent information to assist the City of Well and in the decision making process stated Chantal Brundage, Program Manager of greenTbiz. Ms. Brundage added that We have gained significant input And knowledge through public opinion research in our Toronto LED pilots and LED City (Toronto) efforts and we are pleased to be a part of this project in Welland.
As with other municipalities, such as the parking garage research conducted in Raleigh, NC, USA, important information is learned about public perception and safety. Because of the scotopic value of ED light, visual acuity is increased and the cool white light also offers a Better feeling of safety. Results of the greenTbiz survey will help Welland Council with the decision and process how to further implement LED lights across the City.
Replacement LED lamps
Another prominent LED developer and manufacturer was also showcased during the evening, as CRS Electronics of Welland, Ontario hosted a reception at their facility to honour the event in Welland.
CRS unveiled its direction in LED interior lighting to the group of dignitaries and inviting guests. Known for years of experience with LED in the transportation industry and with many other architectural and military applications, CRS has developed an LED solution to the MR16, which is typically Implemented with halogen technology, and the linear tube, which has typically been fluorescent.
I am pleased to be a part of this vision in Welland and to take a local company to the international stage. commented Scott Riesebosch, President of CRS Electronics, adding This good for Welland, for Ontario and Canada and for the environment throughout the world.
Recently back from eeGLOBAL in Washington, DC, USA, an international energy efficiency exposition and forum, CRS has received overwhelming interest in the new products and has been awarded a substantial contract to retrofit an entire 44-story condominium building. LEDs Magazine will be following This story with further details to come in the New Year. Dignitaries and guests were invited to view the new LED products and to tour the production line at CRS.
Ontario Power Authority recognition
Following the reception at CRS, Chief Conservation Officer Love attended at Welland City Hall to present Mayor Goulbourne and Council with a Certificate of Recognition Award for their leadership leadership in energy efficiency with this LED project. “We at the Ontario Power Authority believe that energy efficiency "the City will save money that can be put to use elsewhere. Well the is definitely setting an example for others to follow."
Welland now joins the efforts of many cities exploring LED technology in their municipal applications. Welland may only have a population of just around 50,000 compared to Torontos 2.5 million and may only have just over 6500 street lights also compared to Torontos 160,000, but they have to Be given credit to investigate a commitment to go all the way with 100% LED over 3 to 5 years, definitely making Welland a strong contender to join the ranks of others in the LED City program.
The City of Welland will continue to explore pilots with LED roadway lighting manufacturers. At present, they are also in discussions with Leotek / electromega, CRS Electronics, RUUD Lighting and NeoPac for the purpose of reviewing product and developing pilot installations. Much of the success Of the projects and the overall program can be attributed to Dave Ferguson, Manager of Traffic and Parking Operations, who leads this initiative.

Male DVI Connector

Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units. This series includes DVI-D (Digital), DVI-A (Analog) and DVI-I (Integrated Digital/Audio). Their unique crossing ground blades provide high speed performance at low cost. They are available in Straight or Right Angle PCB mount receptacles and mating male cable connectors. They support a data transfer rate of 4.95Gbps with a dielectric withstanding voltage of 500VAC. Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).



Digital Visual Interface Cable Connectors

DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.


Digital Visual Interface

Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.


Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.


Types of DVI Connectors

There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.


A standard DVI Connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.

DVI-I Single Link

This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.

DVI-I Dual Link

A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.

DVI-D Single Link

Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.

DVI-D Dual Link

Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.

DVI-A

This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.
