The LED bulb is a new type of lighting based on the technology of LEDs. It emits light through an electric current. It is more economical, lasts longer, instantly lights up, is aesthetic, heats less than halogen and emits less radiation than compact fluorescent lamps.
First, say “LED” is making Anglicism, indeed, we should say “DEL” (for light-emitting diode). LED is an acronym for Light-Emitting Diode. When we talk about LEDs, we tend to think of this type of diode:
This little red chip was invented in the 60s and it was not until 50 years later we will start to use it as energy saving lighting bulbs. According to most estimates, LED lighting will dominate at least 75% of the market within 10 years. Be one of the first to innovate and enjoy!
What does an LED lamp look like?
One might legitimately wonder how a chip of just 1cm can illuminate. It was enough just to consolidate dozens and sometimes hundreds of LED together to give this kind of bulbs LEDs:
LED bulb E27 left, and LED bulb GU10 right.
LEDs called “DIPS” were the LEDs of first generation, now we find LEDS SMD, LED COB etc. Due to these numerous possibilities , we easily find the equivalent of our light bulb, our flame bulbs (candelabra) or downright LED neon lights.
The LED bulb is therefore simply a base with a light source powered in 12V!
The LED bulb comes in different models:
LED lighting is everywhere, it can be declined in spotlight, LED panels, auto LED, but also serve for our classic GU10 bulb, E27 bulb, LED bulb G4, LED bulb G9. Thanks to SMD LED technology and COB LEDs, there are also LED tubes and LED spotlights.
The LED lamp can offer a very wide and diversified luminous flux:
It is possible to have a color range from red to green to blue (RGB or RGB LED). The “temperature”, that is to say the color diffused by an LED bulb is measured in kelvin, it goes from the yellow light, to the white light passing by the bluish.
LED lighting consumes less than other types of lighting:
Consumer Comparison 35 000h usage, about 15 years, between a LED bulb E27 , E27 and a CFL bulb incandescent bulb E27 60W equivalent lumen:
|60W Incandescent Bulb||Fluocompact EQ 60W||LED Bulb EQ 60W|
|Unit price||1 €||4 €||24.45 €|
|Number of units consumed in 35 000h||35||6||1|
|Total cost in electricity consumption for 35 000H of use (15 years for 6H per day)||267.75 €||55.75 €||26.75 €|
|Total cost of electricity + Cost of bulbs over 35 000H||€ 302.75||79.75 €||51.20 €|
