Bright Future of LED Lighting

Next to CFLs, you can find lamps made up of several LED bulbs collected (or luminescent diodes, Light emitting diode): these can work 100 000 more hours as a light bulb to ordinary filament with a much higher performance.

How Do LEDs Work?

No filament in the bulb but layers of semiconductor materials, aluminium nitride and phosphorure of gallium, which no resistance to the current, and do not entail so no loss of energy.

When an electric current passes through the semiconductor layers, electrons outnumbered encounter atoms charged positively, which releases energy in the form of light.

The LEDs have been used for 40 years for signage applications (Calculator, light appliance…). The technology of LEDs has grown steadily since then and first led lighting applications now exist.

If you can find on the market, they still remain
difficult to be found. Some large areas of DIY or online sites.

The Advantages of the LED

  • The lighting of the LED is instantaneous,
  • the LEDs have an insensitivity to the repeated ignitions and low temperatures,
  • LEDs have a superior in the CFL (low consumption) impact resistance,
  • LEDs give off very little heat, and remain cold,
  • with a virtually unlimited LED life expectancy ranging from 50 000 to 100 000 hours (is 5 times more than a CFL defined at Act-test-centers.com)
  • LEDs are ideal for a point light (night light bedside lamp, Garland…),
  • LEDs consume only 210 kWh, against 390 for CFLs

We can equip a House of almost invisibly with devices LED to a few millimeters camouflaged in the walls or ceilings.

They are visible only lit. More shades or ceiling to buy.

LED – Again to Make Progress

The LED technology is excellent, if not yet perfectly mature for general lighting. Only, the LED cannot, today replace any other type of light source because their beam of light is still limited and few strong powers are available on the market.

Another brake on their purchase: prices that remain very high to buy, even if in use, LEDs are extremely profitable (40 euros the unit against 50 cents for a bulb old-fashioned).

In addition, if they contain no mercury, LED lamps are composed of electronic circuits; they must be collected at the end of life for their recycling.

LED, Light Bulbs Low Consumer of the Future

Major LED manufacturers such as Osram or Philips are estimated at EUR 13.5 billion per year market…

But LEDs are today that a tiny fraction of the lighting market, or about 0.5 percent. These bulbs are still reserved for decorative use or fill light pending progress on the part of the industrialists who are LED as light sources for the future of lighting
domestic.
