New Seat Leon FR 2020

New Seat Leon FR 2020 Interior Exterior.

Since 1975, SEAT's Technical Centre has developed all the illumination technology for SEAT models. In order to reproduce real conditions in night driving, it has an optic tunnel for testing and validating systems that give these cars both the greatest visual comfort and the maximum safety possible. The driver receives 90% of their information through their sight, therefore illumination technology, both for seeing better and for being seen by other road users, is a key element of safety in the vehicle.

On the other hand, the lighting groups are a fundamental piece in the design of a vehicle and one of the elements that bring the most personality to it. Illumination technology has advanced greatly in the last two decades, with the introduction of xenon headlights, LED lights and assist and dynamic illumination systems. Born in 1999, the SEAT Leon has been adding all these technologies in a process of constant updates. In its latest version, it has taken illumination technology to the highest level.

Since the first generation, the SEAT Leon has stood out in the field of illumination, both for its design and for its lighting capacity. The first Leon was already ahead of its time, with powerful halogen headlights in a teardrop shape and prominent rear lights that ran from the rear spoiler across most of the boot. For lighting both on the exterior and inside the cabin, filament bulbs were used, although for the low and high beams halogen bulbs were used; an evolution from the incandescent bulbs in an inert gas atmosphere with tungsten filament and a small amount of a halogen, such as iodine or bromine. The halogen headlights with H7 bulbs provided up to 450 lumens of intensity (luminous flux on the road; low beam) and a light colour temperature of 3,200 Kelvin (slightly whiter warm light), with a consumption of 55 watts in the low beam.

The fog lights were standard, and the driver could regulate the height of the beam using a control button, in order to avoid dazzling other road users and allowing the greatest reach possible, regardless of the load in the vehicle.

Between 2005 and 2012, the SEAT Leon started to introduce new illumination technologies in a constant process of evolution and improvement. Since its release, it has allowed customers, for the first time, to choose between halogen or bi-xenon technology for their headlights, with gas discharge lamps for both low and high beams. This technology offers greater luminosity, (850 lumens compared to 500 with halogen), consumption that is 35% lower and a longer life. Also, the whiter colour, with a temperature of 4,000 Kelvin degrees, reduces eye fatigue for long journeys at night.

The technology includes a device that automatically and dynamically regulates the headlights. Using two sensors and an electronic control unit, the position of the beam of light is automatically adjusted depending on the load, the acceleration and braking, which increases safety and avoids dazzling others.

Another improvement is the automatic connection of the lights, which allows the driver to forget about them, even when entering a tunnel or carpark.

However, the second-generation SEAT Leon offered a greater number of innovations, such as illumination for bends through the front fog lights (available after model’s midlife update) or, in combination with the bi-xenon lights, the dynamic illumination for bends, which through the sideways movement of the headlights follows the outline of the road. In this way, the driver detects the angle of the bend ahead of time, increasing safety and confidence while driving.

The LED headlights in the third-generation Leon have six light-emitting diodes for the low beam and three more for the high beam, with a consumption of 20W per headlight (low beam). The LED permit functions that were not available until that time, such as the possibility of varying the height of the beam in two anticipated situations, when exceeding 110 km/h for over 30 seconds and when changing to the low beam. One added advantage of these LED headlights is that they do not use fans in the heat sinks, which permits reduced electrical consumption and the removal of a source of noise.

In this generation, the Leon also benefits from driver’s assistance systems, such as the automatic change between low and high beams and a device that detects when there are other vehicles on the road thanks to a camera located between the windscreen and the rear-view mirror; both those coming towards us from the front and those that we are going to overtake, so that the lights don’t dazzle them.

The fourth-generation SEAT Leon is the most advanced vehicle in the history of the brand. This also translates to its cutting-edge illumination technology, bringing LEDs to a level of sophistication and efficiency that were previously unknown. In this model, the halogen lighting completely disappears.
