Light Bulbs That Don’t Waste
No matter where you go nowadays, people are always talking about “green” products and ideas. There are also more and more of these coming onto the market and the goal is to help the planet by wasting less energy. As a result, products we never thought would leave are being replaced with new technology. One example is the light bulb.
The wonderful invention of the light bulb was in 1879 by a man named Thomas Edison and he would be surprised at how the world depends on it. His light bulb was a replacement for the old kerosene lamps. Today the incandescent light bulb, unfortunately, is an energy draining product which emits a strange yellowish glare and is the most inexpensive choice found.
The 1920s brought fluorescent lighting to commercial buildings and garages where a more even light distribution was desired. This type of lighting cut generated heat by up to 75%, compared to the light bulb, and seemed to be a good replacement to the light bulb. But the fluorescent bulb has many drawbacks and is not friendly for residential use. The tubes are large and filled with mercury, temperature sensitive and prone to intermittent flickering not to mention the problem of disposal.
It seems that energy consumption, sometime in the 1970′s, really began to take form and thus the birth of the tungsten halogen lamp or quartz lamp. The light from this bulb is far better than the incandescent light bulb, also needs lower voltage and its life span is much longer. It is becoming more popular only recently with emphasis on energy consumption but before people were not so quick to change, in part, because of the cost.
In the 1960s the best discovery of all was made and the alternative lighting was known as LED. This is a product made of a silicon element which is able to convert electrical energy to light energy, but without any of the disadvantages that regular light types have. This type of lighting was invented by Nick Holonyak and he has received many honors for this amazing innovation.
The light emitting diode, or LED, is different from all other light bulbs. LED lights are the same as the red indicator lights on electronic devices which show if it is on or off. What makes these lights different is that LED lights give off no heat or distorted tint, they have no movable parts and have a long life. On top of that, they are also very energy efficient.
New technology is running with this great new invention and have designed bulbs to replace street lights, decorative lighting and LCD displays in traditional flat screen TVs. The initial installation cost is still relatively high but the savings and benefits are so great that before long, every light bulb will be replaced with the energy saving LED. Who says you can’t build a better light bulb? It has just been proven that you can.
