Vidya Balan & Pakistani Cricket legend Wasim Akram are joining Gateway of India, Taj Hotels in Mumbai and Delhi, India Gate, Chhatrapati Shivaji Terminus in Mumbai, communities and businesses to promote “earth hour.” Earth hour is about switching off the lights for some time. But, once you switch on the lights, you have an option of dimming the lights.
In 1960, the Founder of Lutron, Joel Spira invented the first ever energy-saving electronic dimmer. Before that, dimming was done with bulky rheostat dimmers which could only dim by transforming electricity into heat without saving any energy at all.
Dimming helps households and organisations alike to make a significant contribution towards the protection of the environment by reducing energy consumption, lamp replacement and all associated costs. Other benefits being an increase in comfort level, the prevention of distractions, the ability to enhance moods, the extension of lamp life and just having the convenience of choice. Here is some statistics. If you dim 10 %, you save 10% electricity and your bulb will last twice as long. If you dim 25 % your, you save 20% electricity and your bulb will last 4 times more. If you dim 50 % your, you save 40% electricity and your bulb will last 20 times more. And, If you dim 75 % your, you save 60% electricity and your bulb will last more than 20 times more.
The key to dimming is TRAIC (TRIode for Alternating Current). At the heart of any dimming component, an electronic switching component allows current to flow in either direction. It allows light to be switched on and off very rapidly – approximately 120 times a second. The longer the light is on vs off, the lower is the light output.
The beauty of dimming is that by dimming 10%, your naked eyes won’t even notice the difference in light level as your pupils will automatically enlarge to allow more light in. So you can virtually save energy without noticing the change in light level. Beside, dimming can give you the desirable light level for different activities. Some activities like reading require brighter light level while other activities like dinning or listening to music need lower level and more ambiance.
Lutron has a range of shade and blind controls allow natural light levels to be maximised, offering the ultimate in efficient artificial and natural lighting control. Lutron leads the industry in controlling energy efficient light sources and full-range dimming is now possible for a wide range of fluorescent lamp types. The trend toward LED lighting for accent and general lighting is growing and Lutron has products to control LED lights too.
