What does LED Stand for

Light-emitting diode (LED or LED) are electronic devices used for a long time to make lights (the light turning on your computer, for example).

What does LED Stand for
The main feature of led bulbs is that you can control precisely from their making the wavelength of the radiation they emit, instead of an incandescent light bulb, which emits on the whole of the spectrum into the infrared. And it’s far from being a trivial technicality! In fact, the d show “infrared:”

* does nothing in terms of brightness (it is a light frequency that the human eye does not perceive)
* induces a rise in the temperature of the device.

7 percent of the energy used by an incandescent bulb is transformed into light, the remaining 93% being lost in heat! A 60-watt incandescent bulb emits so for 4.2 Watts in the visible radiation. This represents a waste of energy (unless you don’t chauffiez you to bulbs?) and reduced bulb life expectancy: alternating hot-cold it is worthless… A compact fluorescent bulb does a bit better, but is far from achieving the effectiveness of an LED bulb.

Led bulbs by Ledbulbbay also offer the big advantage compared to compact fluorescent light bulbs do not contain mercury.

. The highly competitive cost of LED bulbs, opens already fields of specific applications, including the signage as a panel of emergency lighting and traffic lights.

The replacement of incandescent by the lamps to LEDs presents three interests:

– Led light bulbs reduce energy consumption.
– Light bulbs, leds reduce maintenance with their much greater longevity.
– Bulbs leds also offer greater security because the colorful light bulbs LEDs avoids laying of caches of color on the boxes, thus significantly improving the visibility.

During the implementation of the operation led bulbs, saving electricity was estimated at 32 €776,54 / year and economy of maintenance at 22 €105,11 / year, a total estimated at €54 881,76 for an investment of €167 693,92. Time to return on investment therefore amounts to three years. The results of the first campaign in fact exceeded expectations in terms of saving on the electricity station.

LED bulbs have also found application in developing countries. Irvine-Halliday, an electrical engineer has developed a LED lamp runs on rechargeable batteries from renewable energy (pico-turbines, small wind turbines and solar cells). Its use could eventually replace the lamps running on kerosene, dangerous and ineffective. Irvine-Halliday has created the Light up the world Foundation, to promote this type of lighting in developing countries.

This initiative is all the more justified that found that a village of about sixty families using LED bulbs will use the same amount of energy as that consumed by a single incandescent bulb of 100W.

In a different field note that Bulbs LEDs are much appreciated by the great Designers since the technology allows to develop new forms and offers a wide variety of color. Artemide, Lucepla, Ingo Maurer have already developed lamps technology Led light bulbs-based desktop or ceiling lights.

There are two main families of Bulbs LEDs: inorganic (LED) and organic (OLED).

-The organic LEDs bulbs are developing, and the first applications will appear just on the market (ex: screen color MP3 player).
-Bulbs LEDs inorganic classics are boosted (diodes) P – N junctions in order to emit a visible or ultraviolet radiation when a current passes through in the passing sense. The radiation emitted by a classic (red, green) LED bulb is almost monochromatic (spectral line). The influence of white Bulbs LEDs is dichromatic or polychromatic following the technique used.

In addition to their attractive aesthetics, their low consumption and OD lives extended, led bulbs are very resistant to shocks and are immune to repeated ignitions and low temperatures. Only fly in the ointment, white LEDs light bulbs generate a phenomenon of halo of very strong luminescence from blue light, which can pose a risk to the eyes if we fixed the light directly.
