Buying the Perfect Energy-Efficient Light Bulb in 5 Easy Steps


I can remember the day I bought my first light bulb. The row of light bulbs varying in wattage, color, size, and shape was enough to make me break out in a cold sweat. I ended up buying a light bulb with the wrong number of watts and nearly melted my lamp shade.

New Lightbulbs: What’s the Difference?


Traditional incandescent bulbs use a lot of energy to produce light and are no longer manufactured.

90% of the energy is given off as heat

That lost energy is money we are throwing away

Newer energy-saving lightbulbs provide the choices in colors and light levels you’ve come to expect. The new lights are also much more efficient — so they save you money.

LED Lighting


The light-emitting diode (LED) is one of today’s most energy-efficient and rapidly-developing lighting technologies. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting.

Residential LEDs — especially ENERGY STAR rated products — use at least 75% less energy, and last 25 times longer, than incandescent lighting.

Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 TWh (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1000 megawatts each), and a total savings of more than $30 billion at today’s electricity prices.

How Light Emitting Diodes Work – What is a Diode?


BY TOM HARRIS & WESLEY FENLON

At the junction, free electrons from the N-type material fill holes from the P-type material. This creates an insulating layer in the middle of the diode called the depletion zone.

When the negative end of the circuit is hooked up to the N-type layer and the positive end is hooked up to P-type layer, electrons and holes start moving and the depletion zone disappears.

When the positive end of the circuit is hooked up to the N-type layer and the negative end is hooked up to the P-type layer, free electrons collect on one end of the diode and holes collect on the other. The depletion zone gets bigger.
A diode is the simplest sort of semiconductor device. Broadly speaking, a semiconductor is a material with a varying ability to conduct electrical current. Most semiconductors are made of a poor conductor that has had impurities (atoms of another material) added to it. The process of adding impurities is called doping.

In the case of LEDs, the conductor material is typically aluminum-gallium-arsenide (AlGaAs). In pure aluminum-gallium-arsenide, all of the atoms bond perfectly to their neighbors, leaving no free electrons (negatively charged particles) to conduct electric current. In doped material, additional atoms change the balance, either adding free electrons or creating holes where electrons can go. Either of these alterations make the material more conductive.

At the junction, free electrons from the N-type material fill holes from the P-type material. This creates an insulating layer in the middle of the diode called the depletion zone.

A semiconductor with extra electrons is called N-type material, since it has extra negatively charged particles. In N-type material, free electrons move from a negatively charged area to a positively charged area.

A semiconductor with extra holes is called P-type material, since it effectively has extra positively charged particles. Electrons can jump from hole to hole, moving from a negatively charged area to a positively charged area. As a result, the holes themselves appear to move from a positively charged area to a negatively charged area.

A diode consists of a section of N-type material bonded to a section of P-type material, with electrodes on each end. This arrangement conducts electricity in only one direction. When no voltage is applied to the diode, electrons from the N-type material fill holes from the P-type material along the junction between the layers, forming a depletion zone. In a depletion zone, the semiconductor material is returned to its original insulating state — all of the holes are filled, so there are no free electrons or empty spaces for electrons, and charge can’t flow.

To get rid of the depletion zone, you have to get electrons moving from the N-type area to the P-type area and holes moving in the reverse direction. To do this, you connect the N-type side of the diode to the negative end of a circuit and the P-type side to the positive end. The free electrons in the N-type material are repelled by the negative electrode and drawn to the positive electrode. The holes in the P-type material move the other way. When the voltage difference between the electrodes is high enough, the electrons in the depletion zone are boosted out of their holes and begin moving freely again. The depletion zone disappears, and charge moves across the diode.

If you try to run current the other way, with the P-type side connected to the negative end of the circuit and the N-type side connected to the positive end, current will not flow. The negative electrons in the N-type material are attracted to the positive electrode. The positive holes in the P-type material are attracted to the negative electrode. No current flows across the junction because the holes and the electrons are each moving in the wrong direction. The depletion zone increases. (See How Semiconductors Work for more information on the entire process.)

The interaction between electrons and holes in this setup has an interesting side effect — it generates light! In the next issie, we’ll find out exactly why this is.

How Light Emitting Diodes Work


BY TOM HARRIS & WESLEY FENLON

Though they often come in tiny packages, light emitting diodes produce a large amount of light and are used in an ever-growing list of technologies. See more electronic parts pictures. ©ISTOCKPHOTO.COM/JAMERSONG
Light emitting diodes, commonly called LEDs, are real unsung heroes in the electronics world. They do dozens of different jobs and are found in all kinds of devices. Among other things, they form numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo television screen or illuminate a traffic light.
 

Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don’t have a filament that will burn out, and they don’t get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The lifespan of an LED surpasses the short life of an incandescent bulb by thousands of hours. Tiny LEDs are already replacing the tubes that light up LCD HDTVs to make dramatically thinner televisions.

Things to Consider When Buying LED Lighting


Source:  1000Bulbs

Things to Consider When Buying LED Lighting

Equivalent Wattage – While lumens are the new standard, it helps to have an easily recognizable guide. Comparing an LED bulb to an incandescent will give you a rough estimate of just how well it will light a room. As a very ballpark figure for LED wattages, 1/4 or 1/5 the incandescent wattage value is usually close to what you need.

Lumens – Lumens directly measure just how much light the bulb gives out in total. On average, a 60-watt incandescent shines at 800 lumens, with roughly 50-100 lumens of difference above or below. The variance depends on manufacturer and age of the lamp. LEDs are directly rated for their max lumen rating and last much longer without dimming of the bulb.

Color Temperature – Your guide to how the light itself will look. Lower values are warmer, with 2700-3000K being a more incandescent “warm white” while higher temperatures like 5000K will deliver a very harsh “stark white” light. Our Lighting Guide lets you select a color temperature and see how it transforms a kitchen.

Driver Content – Because of their design, LEDs do not typically run on AC voltage. Many LEDs require some form of driver to convert the voltage from AC to DC for proper operation. The majority of socket-based LED lamps are self-driven, but you should always check before buying to make sure that you buy both an LED and a driver at the same time if it isn’t self-driven.
