The BBC recently put together a video about the LED Lighting Revolution that was jam packed with lots of information about the latest advances in LED lighting for 2013. It also brings great video of LED upgrades to the Times Square New Year’s Ball in New York and the new LED lighting at New York’s Empire State Building that you might not have seen yet.
The New Year’s Celebration at New York’s Times Square is known worldwide for the crystal ball that has been dropped at midnight since 1907. The ball, made by Philips and Waterford, got a makeover in 2007 when they changed the light source from incandescent bulbs to LEDs. But each year the LED-based ball gets a little bit better. The BBC video details how Philips and Waterford joined together to ensure that the legendary sparkle of the ball wasn’t lost with LED’s directional light. The ball designers used special reflectors and baffles (seen in the video) to make sure the light refracts correctly with the crystal.
The 2013 Ball features 2,688 Waterford Crystal triangles bolted to 672 LED modules attached to an aluminum frame. The Ball is illuminated by 32,256 Philips Luxeon Rebel LEDs. Each LED module contains 48 Philips Luxeon Rebel LEDs – 12 red, 12 blue, 12 green and 12 white to a total of 8,064 of each color. The Ball is capable of creating a palette of more than 16 million colors.
Not only does the ball look better, but the new ball brought energy savings 90% with double brightness by going LED in 2007. One year later, improvements saved 30 percent more energy. The improvements have been so great that they keep the ball lit all year, every day.
The LED retrofit of the Empire State Building (ESB) was completed earlier this year, but the people at the BBC show the retrofit developed by Philips Color Kinetics in detail. The new programmable LED light system brings 16 million colors. The old lighting system for the ESB meant 9-10 men manually changing large colored gel disks in a process that took all day. Now, the managers can update the new color palette – which can be daily — at a touch of a button.
Recently, we detailed the new 3-Way SWITCH LED Light Bulb at CES. The BBC video details how some SWITCH bulbs are made with a new liquid cooling system. While most LED bulbs are air cooled, the people at SWITCH have developed a special liquid cooled LED bulb. SWITCH’s advanced LQD Cooling System™ divides the bulb into two parts where half the bulb is a glass globe filled with silicon-based liquid to act as a cooling element. The LQD Cooling System also includes a patented driver that is both reliable and highly efficient. SWITCH claims that their bulbs offer up to 40% better thermal performance than air-cooled LED bulbs.
The BBC video ends with a look at how 2013 will be different for personal, customizable LED lighting that can be controlled by a tablet or smart phone. Using an onscreen color palate or personal photo on a tablet, users can change the light from the LED lamp.
