A short history of the light bulb

The electric light bulb is one the most abiding symbols of technical advancement. From its early conception at the turn of the 19th century to the present day where the image of the light bulb is still used to represent the notion of a good idea, the design of the light bulb has changed relatively little. However, with efficiency requirements and customer tastes becoming more advanced lighting technology is once again changing rapidly. In this article I will chart the progress of the light bulb, starting with the earliest experiments with platinum filaments to today’s most advanced LED bulbs.

One of the most consistent and interesting themes in this subject area is the aversion to change that inventors and innovators contend with at each new technological advancement. This point can be illustrated with the candle light bulb; the bulb was designed to replicate the aesthetics of a candle in fittings such as chandeliers (the earliest chandeliers were purely functioning as a way of increasing the light output from candles). The candle shaped bulb is now one of the most popular CFL styles due to the potential cost savings from multiple bulb fittings.

When discussing the incandescent lamp one name features more prolifically than any other, Thomas Edison. Historians Robert Friedel and Paul Israel named over twenty inventors of the light bulb before Edison, however they concluded that Edison’s design surpassed earlier attempts because of effective incandescent material, a higher vacuum and higher resistance making the bulb easy to power and therefore economically viable.

Thomas Hughes ascribed the success of Edison’s design to the fact he had invented an entire lighting system, ‘other inventors with generators and incandescent lamps, and comparable ingenuity and excellence, have long been forgotten because their creators did not preside over their introduction in a system of lighting’ (Hughes).

The first incandescent light was created by Humphry Davy in 1802, 45 years before Edison was born, by passing an electric current through a thin strip of platinum, chosen for its high melting point. The light produced was not bright enough nor did it last long enough to be practical.

James Lindley took up the baton in 1835 demonstrating his electric light at a public meeting; however he then turned his attention to other fields leaving the way clear for Walter De la Rue. In 1840 De la Rue passed an electrical current through a coiled platinum filament- enclosed in a vacuum. The theory being that an evacuated bulb would contain fewer gas molecules to react with the platinum, thus prolonging its illumination time. This was a significant advancement; however the use of platinum made the design unfeasible for commercial use.

In 1858 Joseph Wilson Swan began working with carbonised paper filaments but was hindered by the lack of a good vacuum until he teamed up with Charles Stearn, an expert on vacuum pumps. Swan then turned his attention to efficiency, producing better carbon filaments, and in 1880 he began installing light bulbs in his home in Gateshead, England.

Thomas Edison began research into the incandescent lamp in 1878, settling on the carbon filament. His first test in 1879 lasted for 13.5 hours, however several months later Edison discovered that a carbonised bamboo filament could last for over 1200 hours.

Meanwhile in the U.S Hiram S. Maxim started his United States Electric Lighting Company becoming the second man, after Edison, to install incandescent lamps at the Mercantile Safe Deposit Company in New York City. Edison and Swan joined forces to form Ediswan (later to become Thorn lighting), and eventually Edison acquired all of Swan’s interests in the company.

Advancements continued and in 1910 William David Coolidge invented a method of making tungsten filaments more efficient, making the light bulb even more cost effective.

From 1913 to 1930 innovators turned their attentions to the use of inert gases in the bulb to improve efficiency further. In 1930, Imre Brody settled on a mix of krypton and xenon and to reduce costs, also developed a method of capturing krypton from air at his factory in Ajka, Hungary.

The latest significant development in the lighting sector has been the introduction of ‘energy saving’ light bulbs or compact florescent light bulbs (CFLs). Although they are considered a relatively modern invention CFLs were first conceived by Pete Cooper in the late 1980s and were originally used in the photography industry. The first practical florescent lamp was designed by George Inman from General Electric and became the blueprint for the modern CFL invented by Ed Hammer and General Electric in response to the 1973 oil crisis. Although the design met all of its requirements, it was never mass manufactured due to the cost of mass production, however the design was subsequently leaked and copied.

The steady increase in CFL production continues to this day but with the phasing out of inefficient incandescent bulbs, consumption is expected to increase more sharply. By September 2012 no incandescent bulbs will be available reducing carbon emissions and consumer energy costs.

So what is the future of electric lighting? Many people believe that the answer lies with LED bulbs. Originally used in devices such as alpha numerical displays and pocket calculators the LEDs have recently seen successful application in commercial and domestic lighting. LEDs can last for up to 50,000 times as long as incandescent bulbs and the most advanced bulbs can produce a high light output while consuming a fraction of the energy. Although the initial cost of the lighting is high, the bulbs will more than pay for themselves in their lifetime. LED bulbs have a fast on/off time and can withstand a high frequency of cycling making them ideal for car headlights, theatrical spotlights, traffic lights and dynamic road signs as well as household and domestic lighting.

It is clear that lighting technology has come a long way since Edison’s first experiments and the contact we have with lighting everyday encourages advancements to continue.

Hate Energy Saving Light Bulbs? Heres A Bright Idea..

When it was announced in January last year that the European Union was banning incandescent light bulbs – the ones we’ve traditionally been used to – a lot of people in Britain were hopping mad (please note I resisted the temptation to say ‘incandescent with rage’). They didn’t like those new fangled compact fluorescent (CFL) energy saving light bulbs, not least because it was someone in Brussels trying to shove them down our throats, screw them in place and light up our mouths with them! (Not literally of course). But for one thing, they come in funny shapes that stick out of the top of lamp shades, and they don’t shine as brightly as proper light bulbs, and they have to warm up before they get to full brightness – surely that’s a step in the wrong direction!

All this fuss led to a Light Bulb buying frenzy, with people stocking up on traditional light bulbs, and the Daily Mail newspaper even giving away 25,000 incandescent light bulbs to its readers! But despite all this commotion, energy saving light bulbs were here to stay, so thank goodness someone took up the challenge to make them better! Witnessing the outrage felt by the people of Britain at being force fed oddly shaped bulbs (not literally), the nice people at Ledon had a bright idea, a light bulb moment you might say (groan). And so they set out to replace the CFL energy saving light bulbs with something better, which is why they created… fanfare moment… the LED light bulb.

Not only are Ledon LED bulbs shaped like, well, like light bulbs, they whack out their full brightness the instant they are switched on – so at least we are back to where we started! But then there’s a whole bunch of other reasons to think LED bulbs are the bees knees. They are far more efficient than long life incandescent bulbs, at least 85 per cent more in fact. You can expect an average lifespan of 25,000 hours for LED light bulbs. That means that with typical usage your LED light bulb could have a lifespan of 25 years! It would last nearly three years without ever turning it off, if you are so inclined, although switching it on and off does nothing to shorten the lifespan of this amazing bulb. They also use five times less energy than the old bulbs!

LED light bulbs are also much more efficient than those CFL energy saving light bulbs everyone hates. While a CFL bulb might last 8-15 times longer than an incandescent bulb, its lifespan will be significantly shortened if it is switched on and off regularly. In comparison, an LED bulb can be switched on and off as often as you like, and it will still last 20 times as long as a traditional bulb. CFL bulbs contain mercury, which is bad for us and makes disposal more difficult, but LED light bulbs contain nothing but goodness and light, errr, probably. OK, the science part isn’t important, but they certainly don’t have anything nasty in them, and you won’t have to worry about disposal anyway because they will probably last longer than you do. Light quality is as good as traditional incandescent bulbs, and there are no health issues associated with LED bulbs, unlike CFLs which have been known to cause adverse affects on people with epilepsy, migraine sufferers, people with lupus and even autism. So the basic message is this – the only bright thing to do is get LED light bulbs in your home.

Watt Power

Moving Toward Net Zero Energy – Watt Meters

For many people, the only thing they know about electricity is that they use it and get a monthly bill for that use. Volts, amps, watts, and kilowatt hours are a foreign language. In order to start reducing your electric bill, it is helpful to find out how much energy different parts of your house are using .Watt meters are very helpful devices to accomplish this.

There are two basic types of Watt meters. The first type is a plug meter designed to measure individual appliances. Simply plug your appliance into the meter, and plug your meter into the wall. With this information, you can quickly identify inefficient items. The second type of meter is a whole house meter which can be located in a convenient place in your home (the kitchen countertop for example), and will show you how much energy your home is using at any specific time, as well as cumulatively for the day and for the billing cycle.

A watt meter tells you how much power is being used. If you plug a 60 watt reading light into a watt meter, it should read something close to 60 watts. If you use that reading light for 3 hours a day for a month, you will have used 60 watts x 3 hours/day x 30 days = 5,400 watt hours. A good watt meter will allow you to leave something plugged in and will tell you both current watts and accumulated watt hours. You buy electricity from the utility company in units of 1000 watt hours or one kilowatt hour (kWh). Kilowatt hours are usually abbreviated kWh. If your utility charges you $.10/kWh, using the reading light for 3 hours a day for a month would cost 5.4 kWh * $.10 or $.54 per month.

What people do not realize is how much energy some devices use when they are off or on standby. For example, a computer uninterruptible power supply (UPS) backup battery with monitor, printer, computer, rechargeable phone, and computer speakers may draw 50 watts even when the system is off. In this case, 24 hours * 50 watts * 30 days * .10 /1000 = $3.60/month to run a computer that is turned off. Most homes have many devices that draw power when they’re off, and this is referred to as a “phantom load”. If your home has 10 devices that draw a 50 watt phantom load all the time, this starts to really add up. In the example above, you’d be spending $36 each month for things that were off or on standby. Not only is this an unnecessary cost, it causes unnecessary pollution as well. Once you’ve identified a phantom load, simply unplug the device when you are not using it, or put it on a power strip and switch the power strip off.

In addition to an instantaneous reading, some watt meters will project monthly kWh and/or cost. This is particularly useful for appliances such as refrigerators with compressors that cycle on and off. You can plug a refrigerator in for several days and the meter will estimate how many kWh the refrigerator will use for an entire month.

There are several brands of Watt meters on the market that will make your home energy audit go faster. The meters we found to do the job best are the “Kill-A-Watt ™” plug meter, the” Watts UP? ™” Plug meter, and the “TED ™” whole house meter.

The Kill A Watt is a good plug meter if you want to mainly measure watts and kWh. It is an inexpensive way to start getting the big picture of how your house is using electricity.

The Watts UP? plug meter adds a power cord to make it easier to use and has many more features such as the ability to project monthly kWh and cost. It also keeps track of many more values such as maximum and minimum. The Watts UP? PRO adds data logging to the Watts UP meter and will record data every second. Once memory fills up, it starts recording every two seconds. You still get good data resolution even after collecting data for a month. The data can then be downloaded into a computer and graphed for a visual of how your energy usage is going.

The TED meter will give second-by-second and daily feedback on energy use for the entire house. Part of the meter is set up inside your breaker box. There is a display unit that can be plugged into any outlet in the house. Most people do not know how much or little energy they are using until the monthly bill comes in. It is too late then to make adjustments. A TED meter is a great way to immediately see how changes in habits and devices affect the entire house energy usage. You might want to think about turning the television off before you go to bed.
