Flared Pin Fin Heat Sinks - an Alternative for Natural Convection
New Heat Sinks are a Fit for Emerging Green Applications
 Cool Innovations, Inc. has introduced a new line of powerful flared pin fin heat sinks. The heat sinks provide unparalleled cooling power due to a unique structure that was specifically optimized for natural convection environments. The new heat sinks feature a rugged array of round pins and are suitable for harsh industrial environments and outdoor applications.
Flared pin fin heat sinks feature an array of round pins that are slanted outwards. The sparsely configured staggered pin array and the flared structure combine to produce outstanding cooling power in natural convection. At the same time, the omnidirectional pin configuration ensures that the heat sinks operate efficiently in any orientation. Flared pin fins offer up to a 30 percent performance premium over traditional pin fin heat sinks, and a substantially larger cooling premium over the majority of other heat sink designs.
Flared pin fin heat sinks are forged from highly thermally conductive aluminum alloys.
They are available in a wide variety of square, rectangular and round configurations, ranging in footprint from 1 by 1-inches to 5 by 5-inches, and in height from 0.7 inches to 2 inches. The heat sinks are a good fit for emerging green technologies such as solar cells and advanced LED lighting, as well as any other applications and devices operating in natural convection environments.

Dialight’s New 100 W LED Luminaire Outshines 250 W HPS
 SafeSite 250 series is Dialight’s latest addition to its innovative SafeSite range of LED fixtures and, using 100 W per fixture, has been created to outperform 250 W HPS lighting sources in several ways. First, by replacing traditional HPS fixtures that require 250 W, the SafeSite 250 series luminaire offers power savings of 60 percent. Second, whereas HPS lamps emit light almost exclusively in the orange area of the color spectrum, SafeSite delivers pure “full spectrum” white light that is much easier to see under. This is especially important in low light level conditions when the eye’s rod receptors are more used in visual acuity than the cone receptors and is critical for tasks like viewing color coded wiring, reading colored plaques and distinguishing steam from the smoke of a fire.
Designed to meet UL Class I Division 2 and Class II Division 2 requirements, SafeSite was originally created to meet the needs of hazardous locations and the new 250 series offers further significant advantages over traditional lighting solutions and its own predecessors. Using the latest 100 lumen/W Rebel LEDs from Lumileds the SafeSite 250 series provides 50 percent more light than the 150 series, lighting a larger area, so stanchion mounts can be placed at 12 feet or higher instead of 8 feet and fewer are needed. With its improved light control and higher fixture efficiency, it outperforms traditional HPS light source technology.
“Making a one-to-one comparison between a 100 W SafeSite 250 series fixture and a 250 W HPS fixture in use 24/7, we calculate that over a year a typical plant with 1,000 retro-fitted series 250 fixtures can save US$164,000 on energy at today’s prices,” said John Peck, manager, Dialight’s Optical Design Group. “But it’s actually better than that. These T4 and T5 rated LED fixtures don’t require a warm-up period and can be operated as ‘instant-on’, reaching full light intensity in a fraction of a second, so the plant could save a lot more by powering down the lights when not needed or using motion control to avoid running them 24/7. On top of that they’d have the added benefit of SafeSite’s 5-year warranty and that means zero maintenance and more cost reduction.”

Recently Center City District threw the switch on a celebratory holiday gift for the City of Philadelphia, illuminating the historic façades along the Avenue of the Arts. Color changing LED lighting, provided by Philips, transformed the streetscape into a multi-color canvas for the holidays and city-wide celebration.
In December, attendees gathered to see the unveiling of the lighting display, which synchronized the score of The Nutcracker to color-changing light shows that danced along buildings along the intersection of Broad and Walnut Streets. In between the sound and light shows, coordinated lighting changes moved up and down buildings along the Avenue of the Arts. Philips ColorGrazeä Powercore and ColorBlastâ Powercore fixtures were used to create the dazzling lighting display. Permanently installed to illuminate nine buildings along the Avenue of the Arts, the lighting will create a vivid nightscape throughout the year. In addition, Philips temporarily illuminated City Hall with its newest fixture ColorReachä Powercore, a high-performance architectural floodlight, which provided color-changing and dynamic effects upon the 548-foot-tall municipal building.
"Philadelphia is the only city in North America to have organized this of type of lighting on such a large scale in their downtown, coordinating installation on cultural and civic institutions and private buildings with multiple owners," said Paul R. Levy, President & CEO of the Center City District.
ColorReach Powercore is the first LED fixture of its kind that can illuminate large-scale buildings while at the same time curbing energy use and reducing maintenance. With more than 5,000 lumens of output and unprecedented light projection of over 500 feet, the fixture brilliantly illuminates grand buildings, like City Hall, with vibrant colors. It consumes just 290 watts as compared to the metal halide fixtures typically used in such applications, which consume 1,600 watts and require the use of filters to produce color.
The permanent lighting displays were designed by The Lighting Practice, a Philadelphia-based firm that specializes in architectural lighting and the architectural firm Vitetta. Entertainment solutions provider
PRG provided system integration support and installation was carried out by Philadelphia's Gordon Electric.
