A hefty amount of energy goes into lighting our homes, workplaces and other public areas. According to United States Energy Information Administration, the number is actually around 15% of all energy generated in the U.S. (commercial and residential) that goes into illuminating our worlds. One of the best contributions to bring this number down and start decreasing power consumption on this front is the integration of LED lights, improving not only on the power usage, but lifespan, environmentally friendly and safety have all been viable benefits. Now has come the time where we gathering key learnings from other sciences, to improve on LEDs even further.
Dyson is a trailblazer on this front. Sure it may be easy to overlook this brand known mostly for their vacuum cleaners, but ambitious among technological improvement nonetheless. Their astute engineering took the form of their CSYS Task Light, powered by a bulb that lasts almost 4 decades. They achieved this by integrating new cooling system for the bulb allowing them to not overheat, usually the demise of standard LEDs. Their cooling design inspired by satellite composition, alters the traditionally round heat sink to an elongated horizontal heat pipe made from aluminum that does a more efficient job drawing away heat, protecting the LED’s phosphorus coating. The design of the lamp itself has 360 degree rotation and sliding arms for easy light adjustment and focus. With a consistent daily use of about 12 hours, the bulb will last for about 37 years before the light source starts to dwindle.
