Where does the LED lighting ?

Key dates :

LED yellow and red green1927 : First patent for what will be called later the LED

1962 : Creation of the first red LED

1970 : This decade marks the first domestic uses (ex : red and green lights of household electrical equipment)


Nobel-prize-physiqu1990 : Creation and development of Blue LED which will allow major new applications (ex : lighting, TV screens and computers)

2014 : Nobel Prize in Physics awarded to three scientists for their work on the blue LED.


Let lamp LED, how it works ?

This is a electronic component at semiconductor (ex : l arséniure of gallium-aluminum, silicon or zinc) which emits light when electric current flow.

Small LED lamp history :

I am positive electric current (+) and I go to meet my opposite the negative current (-), we go to the diode (LED). By meeting us in the diode we choquons, and our meeting comes light.

The LED light is directly produced in various colors by adding one or more chemical components (ex : Rubia) the semiconductor materials.

The performance of LED lighting depends primarily on its quality and installation.


What are the LED lamps advantages and applications ?


LED lighting has a lifetime much longer than traditional lighting. They are effective and can reach 120 lm/Watt.
Its energy consumption is lower and allows a quick return on investment.
On the other hand, its replacement is less frequent and reduces maintenance costs.

LEDs are resistant to shock and vibration.

The LED lighting does not emit no infrared or ultraviolet radiation. This feature makes the LED lighting solution suitable for the food industry, textiles and museums.

instant LIGHT
LEDs emit from the ignition 100% their performance, no warm-up time, unlike saving bulbs.
Furthermore, they allow very many ignitions and extinctions.

LED lamps do not contain fluorescent powder, or mercury vapor, nor other hazardous metals. The lamps are fully recyclable.
