Low Energy Lightbulbs
Are enhanced power bills a cause of worry for you? You can easily slash the consumption of energy by replacing your old bulbs with those manufactured using diodes. It is necessary to go back into the past to understand how lamp technology has changed over the years. Most people associate Thomas Alva Edison with the creation of the first incandescent bulb in the year 1879. Thought there are many others who claim this discovery, the one that Thomas invented was the post practical and efficient. The quality of these bulbs improved over the years and was the traditional source of illumination inside the house. The major disadvantage of such lamps was that they generated lots of heat, wasting energy in the process.
Problems and solutions
The only problem was these bulbs consumed lots of power and used to fuse quickly. The typical 100 watt bulbs used to consume one unit of power per 10 hours. A typical 100 watt bulb used to emit 1600 lumens. The first low energy lights, the tube light (also known as fluorescent lamp) arrived on the scene in the mid 1930s. They were revolutionary in the sense that they consumed far less power that the traditional bulb to emit the same amount of luminance. Apart from that, the choke (also known as ballast)... used to provide a very high initial voltage to ionise the gas inside the tube and turn it on... emitted much less carbon compared to their predecessors. Apart from this, the electronic choke emitted mush less carbon dioxide. The biggest advantage was that these lamps provided much more luminance per watt consumed and the lamps emitted much less heat than their incandescent counterparts did. The disadvantage was that one had to install a bracket to hold the tube.
A new revolution
It was not long before scientists introduced the cold fluorescent lamps. They consumed less power than the fluorescent lamps and hardly wasted any energy in the form of heat. One could install them on the same socket used by the old bulbs. There was no need to install a separate choke since it was included inside the fixture of the lamp itself. These lamps were available in several sizes and shapes. They last much longer too and provide more luminescence. A typical 25 watts cold fluorescent lamp provides 1800 lumens, which is much more when compared with the 1600 lumens emitted by the tungsten bulbs.
The big boss arrives
Scientists did not rest and kept on researching for new technologies. The year 1962 saw the introduction of the LED (light emitting diode). You might have seen the same on the indicator panel of your TV. It was not long before miniature versions of the same arrived on the market. These bulbs hardly require any power and you can power them with a typical 1.5 volt nickel cadmium battery. Since they are available in strip forms with an adhesive background, you can fix them anywhere. Most modern generation cars use the LED lamps in headlights and indicator panels too. Is this the ultimate or will someone come out with another landmark in bulb technology?
