What you need to know about LED bulbs

LED stands for light-emitting diodes. LED bulbs are therefore those bulbs that have light emitting diodes.These are devices that are semiconductor and produce light when an electricity current is passed through them. LEDs are a group of solid state lighting(SSL), just like light emitting polymers(LEPs), and organic light-emitting diodes(OLEDs).

Difference between light produced by LED bulbs and other light sources

LED bulbs produce light that is different from that produced by incandescent and compact fluorescents.LED lighting is durable, versatile, long-lasting, and efficient.

LED bulbs produce light efficiently by using light emitting diodes. Passage of an electric current through the semiconductor material illuminates the light sources called LEDs. A heat sink absorbs the produced heat.

The most common LED colors include green, blue, amber, and red. Surprisingly, there is nothing called ‘white’ LED. To obtain a white light like the one we use in homes or offices, different colors of LEDs have to be mixed or covered using a phosphor object which converts the light color. The phosphor is the yellow material that you usually see on LED products. Colored LEDs are used as indicator and signal lights such as power buttons on computers.

Today, LEDs are incorporated into fixtures and bulbs for lighting applications. LEDs provide a design that is unique due to their small sizes. Some of the LED bulbs look like ordinary light bulbs while others do not, but can be equivalent to bulbs used in traditional lighting. Better LED lights have LEDs built in for a light source that is permanent.

LED bulbs emit light in a particular direction unlike compact fluorescent and incandescent, which emit both heat and light in all directions. LED bulbs are thus energy efficient, and only complicated engineering can be used to produce a LED bulb that shines all round.

An energy star bulb that is of a standard A-type produces light in all directions and is suitable for a table lamp.

Incandescent bulbs use electricity to produce a white hot metal filament, which makes them release heat as 90 percent of their energy.

Basics of LED bulbs

LED bulbs have a longer useful life.They do not fail or burn out, but have lumen depreciation instead, making the light produced to decrease, shifting light color over time. LED bulbs are considered to have completed their lifetime when their light output decrease below 30 per cent.

LED bulbs and heat

LED bulbs draw the heat they produce away from themselves using a heat sink that absorbs and disperse the light to the environment. Thermal management is an important factor for LED bulbs because higher temperatures degrade the light, shortening their useful life. Heat sinks are therefore an important component in LED bulbs.

Poorly designed LED bulbs will flicker, look dim, shift color, give uneven light, and use power even when turned off.

Reasons, why you should use an Energy Star, LED lighting bulb

There are many lighting sources available today. Always choose the one with the energy star label.

High star guarantees high and quality performance in:

  • Light output
  • Color quality
  • Peace of mind with a 3-year warranty

Remember to take your energy star bulb for random testing annually to make sure it meets the standards of an energy star.
