An LED bulb is a term from the abbreviation LED indicating light-emitting diode, or LED to LED in French. This is an electronic component that emits light when a current passes through it. It sounds very modern but in reality, this technology is used for many years for pilot lights on appliances. Today we are evolving around the led. Although we now have bulbs of big powers and that the products continue to evolve, tomorrow, other new things made from the LED will appear!
To understand the flow of light:Discover the evolution of emits light technology:
The incandescent bulb
This type of light bulbs were the first to emerge. Since the invention of electricity, the light is also on leave. No more candlelight evenings, we discover at this time the glass bulb with carbon filament and soon replaced by tungsten. This filament is mounted high temperature to create a light flow. However, this created very brulantes bulbs.We are at the end of the nineteenth century.
The halogen bulb
Here, the principle was the same. Except that inside the bulb, of the low pressure gas were introduced. The glass used is a quartz glass for the bulb to withstand high temperatures. By chemical reaction, the disaggregated particles of tungsten in the bulb will under the effect of the gas being redeposited on the filament but randomly.
This also known as fluorescent light bulb is a bulb that was inspired compact fluorescent tubes businesses. Current flows through the lamp by producing an electric arc. This active arc electrons collide with mercury atoms and produce invisible ultraviolet lamp. This light will then be reflected on the surface of the bulb that contains a fluorescent layer. This latter reaction produces white light.
As mentioned on Digopaul, these LED bulbs are fully electric. They therefore have no gas or particles that could be harmful to humans or the environment. green lighting, they use very little energy to operate!
Very often used in our product sheets, this term refers to an amount of light flows. It measures the light intensity in order to know the illumination it will propose to compare it to blisters that is already known as halogen bulbs.
