Philips Lighting has announced an LED architectural lighting project installed on the historic Big Four Bridge that links Louisville, KY and Jeffersonville, IN across the Ohio River. The dynamic, color-changing solid-state lighting (SSL) is intended to help revitalize the Louisville waterfront and make the pedestrian and bicyclist bridge a destination point in the region.
Philips Lighting has issued a challenge to the regulatory bodies that specify light levels for various commercial-workplace scenarios to reconsider specifications given the broad age range in the workforce. In office scenarios, for instance, Philips said the 500-lx (50-fc) level that’s typically specified for office task lighting is insufficient for workers of age 45 and above. Moreover, Philips has released a widget using Facebook that allows office workers to test the light level in their own office setting. Continue reading
Dubai Municipality, one of the main administrative departments of the Emirate of Dubai government, has signed a memorandum of understanding (MOU) with Philips to convert all of the municipality’s lighting to LED. The agreement embraces all 262 of the municipality’s buildings, including city government offices, schools, public buildings such as courts and sports venues, and transportation buildings. The transformation from conventional lighting to LED is expected to save the Municipality up to 50 percent, roughly 10.5 GWh per year, on its energy consumption. It will also mean a reduction of some 6,200 tons of CO2 emissions per year.

Philips Lighting has revealed laboratory work on an LED-based replacement for fluorescent tubes in which a so called TLED (Tube lighting LED) tube delivered 200 lm/W, including the driver, at a 3000K warm-white CCT. The company said it will bring such a solid-state lighting (SSL) product to market in 18 months to two years.
Philips chose to announce the lab project because of the magnitude of the opportunity for energy savings. Jy Bhardwaj, senior vice president or research and development, said 50% of global commercial lighting uses fluorescent tubes. The best such fluorescent lights operate in the 100-lm/W range so efficiency in that application could double in two years.
In the US, fluorescent lights consume 200 terawatts annually according to Philips. The company said retrofit of all such lighting with 200-lm/W tubes would be the equivalent of 50 medium-sized power plants. Continue reading
