LED Headlights

In Consume Less Power, Highly Resistant, Non Breakable

Useful information about LED headlights, spotlights and working lights for agricultural machinery, heavy vehicles, construction machinery, transport vehicles.

Performance of LED headlights, optics in lighting

The optics in an LED headlight is based on mirrors, lenses and other elements that allow to control the projected light. Optics is a basic element for the efficiency of the headlight.

The headlights of the cars are a good example to show the physics of the glass lens that allows the beam of light to amplify and intensify its range.

In this way, the optics will help direct light, increase intensity and protect from glare. In the case of LED headlights for other heavier vehicles we will not contemplate the possibility of glare, but we will demand the part of energy efficiency.

Why are the futures of LED headlights in the car ?

From the beginning of the 20th century to the present, we have been able to observe the evolution of vehicle lighting systems. Far away are the oil lamps that were used in the first models.

Carbide, incandescent, halogen, xenon lamps, etc. have also been left behind. Now, the usual are LED headlights and even with laser technology. However, in this article we will focus on the LED headlights of the car.

LED car headlights: what are they and how do they work?

LED is the acronym for Led Emitting Diode, or what is the same, “solid state light emitting diode”.

They consist of a diode through which energy flows in only one direction, a cable that joins the two poles of the diode (cathode and anode), a semiconductor emitting material, and a lens that protects the conductive material and produces a beam of polarized light.

To understand the operation of LED car headlights, it is essential to know what a diode is. It is an electronic device made up of two connected conductive materials.

When seen overexcited, the first material of the diode accumulates energy that sends the second material in the form of negative charge.

These electrons combine with the positive charge of the other diode material, resulting in the release of photons.

Depending on the chemical elements present in their materials, they can produce light waves of different lengths and colors.

The development that this technology has experienced in recent years has caused it to be used more and more frequently in cars.

Initially, vehicles began to incorporate LED lighting in the position lights and, subsequently, in the turn signals and the brake light.

The first brands that used this technology were Audi, Volkswagen, Mercedes and BMW
