DIY : Modern Lighting Technology Explained – BFranklin – Medium
Improvements in technology have made how we light our homes ever more efficient. After using open flame sources for millennia, in the past 100+ years we have cycled through incandescent, fluorescent and LED technologies.
Today’s Light Emitting Diodes (LEDs) represent the most advanced and efficient lighting technology available. And after the older lighting sources are phased out over the next several years, LEDs will be the “last bulb standing” on account of their inherent advantages.
For a few minutes we’ll explore the technological differences between traditional incandescent bulbs, Compact Fluorescent Lights (CFLs), and LEDs. You’ll feel more confident about how and why upgrading your home to LED lighting is a great choice for you and your family.
In an Incandescent light bulb an electric current is passed through a tungsten filament, heating it to a temperature that produces also produces light. We can see how this technology is inherently inefficient: far more energy is released as heat than as light. The inefficiency and short lifespan (less than a year) of the incandescent bulb also creates a continual financial drain for consumers.
CFLs produce light by driving an electric current through a gas-filled tube. Gases inside the spiral tube heat up, producing ultraviolet light. A fluorescent coat on the inside of the tube absorbs this energy and emits visible light. While CFLs improve upon the efficiency and lifespan of incandescents, they are still problematic in terms of their light appearance, mercury content, and sensitivity to cold temperatures. Plus, the harsh light quality of CFLs is typically not conducive to an inviting home environment.
LEDs avoid many of the weaknesses of older lighting technologies. As electrons pass through a semi-conductor chip, more energy is converted to light than to heat — allowing LED bulbs to radiate more light for energy used. This dramatically improves the efficiency of LEDs as compared to incandescent bulbs and CFLs. Not only are LEDs more energy efficient, they are also longer lived — in some cases lasting 20 to 30 years.
