What is an LED?
LEDs: Light-Emitting Diode (light emitting diodes) are electronic components that exploit the ability of certain semiconductors, under certain conditions, to emit photons and then to produce light.
White LED lamps are a revolution in lighting systems. They are able to provide, in fact, a lot of brightness against an extremely low current consumption.
Just to make that idea, the LEDs are, the lights that are used in electronic devices, such spies may be spies (typically red, green, or blue) that are found on cars and on all electronic devices we use every day.
The white LED light appeared on the market only in recent times, with fairly high costs and consequently with marginal applications and reserved for special tools.
Here’s where I applied the white LED light
Generally, since the prices of white light LED is substantially higher than other colored LEDs, for the past couple of years, it is not uncommon to see them in portable flashlights, keychains, Garden lights and some other industrial use.
Lately, with an optimization of the production, the costs to make these LEDs came down until it touches spikes that exceed 400%, benefiting so deployment.
Today, however, their production takes advantage of a greater diffusion and, welcome, even and especially the supply coming from the countries of the far East, with very attractive prices and rapid descent.
Not very easy to come by in Italy, on the international lighting market has long made their appearance with GU10 LED light bulbs, both for domestic use and for the use in vehicles: are those formed by countless tiny grouped. Compared to conventional light sources these devices offer many advantages:
-Low voltage Operation;
-Very modest heat dissipation;
-Extremely long life, up to more than 100,000 hours;
-Great energy saving;
-Possibility to change the color by adjusting the intensity of the three primary colors;
-Easy riparazionein if a fault occurs.
Save with LEDs
Probably in the most immediate future with LED lighting technology will displace traditional ones.
Some simple economic considerations there provide plausible reason: despite the high initial cost more in the long run the savings will compensate abundantly investment.
A LED lamp with socket Edison 27 (equal to that of normal bulbs) and running with the same lamp holders to 220 Volt (has an internal transformer) with light output equivalent to that of an average 40 W incandescent bulb, 20/25 euro.
To add though the numerous beneici that it brings: will last 50 times greater than normal incandescent lamp and will consume 20 times less energy; will last 10 times greater than the energy-saving lamp and will consume 7/8 times less energy than this.
The market is still in its infancy and the variables are still substantial, so each evaluation should be considered only as indicative order of magnitude.
Taking into account the greater initial outlay, but also the longest duration and current savings, we can estimate the total annual costs:
- -Euro 15.00 for normal incandescent lamp;
- -Euro 6.00 for energy-saving light bulb;
- -Euro 1.50 for LED lamp
The undoubted advantage, not only for our portfolio, but also and above all for the whole environment, should in centivarci to buy these new tools of light.
