Although it may not seem to be the main thing, the lighting provided by the headlights of a tourism is an element of active safety that must be taken into account, since we spend a great number of hours traveling in the light of the moon. Moreover, not all roads have decent lighting, and most of them are not even illuminated.
As with practically everything in this sector, there are many types of lights, some better and some worse, depending on the use of the vehicle can be profitable or not, some light one way and some others, some spend more and others spend less .Lately we talk a lot about LED lighting, and it is precisely in this type of headlamp where we want to focus and analyze its advantages over halogen and xenon headlights.
halogen lighthouses are the most common but consume more and illuminate less than led
Halogen lamps are the most common in cars we usually see on the roads. Until very few years ago, the exceptions to this type of lighting only occurred in high-end cars or in the higher equipment finishes of average passenger cars.The bulb has inside it with a filament that reaches very high temperatures (around 2,500 degrees) and that it becomes incandescent; hence the emission of light. The light quality and range depend on the bulb itself and the headlight design.
Although it is easy to be founded, its main advantages are the very economical price of the bulb and that the facility at the time of its replacement, since they can be changed by oneself without possessing technical knowledge.Its two main negative points are the higher energy consumption and the lower quality when it comes to lighting. Over time they have advanced and improved, but it seems that there is not much room for improvement.
High-intensity discharge lamps (xenon)
In the late 1990s, the industry began offering xenon as an optional element in high-end vehicles and in the higher finishes of more general vehicles, though almost always optionally and after going through the box with an extra cost .In the middle of the first decade of this century, its use spread and it was no longer necessary to go to very luxurious vehicles to find this standard headlamp.
xenon systems have a white lighting of quality, a good duration and less temperatures, but at the same time are more expensive, have a complex repair and its flash of light can dark to the rest of cars
Its operating principle is similar to that of a fluorescent tube. Inside they have gases, one of them is xenon gas, and two electrodes. When activated, an arc is generated through the gas, which provides illumination.The advantages of xenon systems compared to halogen lamps are their white and higher quality lighting, longer durability, lower energy use, lower temperatures during operation and greater light beam (between 25 and 50% more).
As for the disadvantages of xenon we must mention the higher price of acquisition and complexity when it comes to repair, they last longer than halogen, but also melt over time being much more expensive to replace and its beam of light and its intensity can dazzle other vehicles.
On led headlights lighting does not come from a single led, but from various groups of these Today, many cars are using Best LED headlights. In addition, they are also used a lot in later pilots as they can play an important role in design with their shapes while they are illuminated, as we saw in the test of the Toyota Prius.
In these headlights, the illumination does not come from a single LED, but from several groups of LEDs. An LED diode consumes very little energy in relation to what it illuminates, but the problem is that its luminosity is reduced. This leads precisely to the use of several groups with several diode units each, which is an advantage since it can allow the disconnection of one or more groups of the same headlight while the rest remain on.Obviously, these LEDs are much more powerful than those used, for example, in the red light of a remote control that lights up when we push a button. The only counterpart of them being so powerful is that they can generate high temperatures in the near areas, a reason why in some passenger cars it has resorted to the heatsink of temperature.
The only drawback that LED lighting can present in a market is the purchase price compared to halogen, but looking at it from another point of view, the difference in price with the discharge lamps is invaluable.
the led headlights have a life saving superior to the car, consume little energy, enhance a more innovative design and develop more safe electronic lighting systems Highlighting mainly a longer life than the car itself, low energy consumption, more ease for designers to “mold” both headlights and rear lights and change the design of the car when they are turned on, develop electronic systems that allow circulation by road always with the long ones connected and that automatically deactivates only the module that illuminates the area near a car when approaching and a white light and clear.Moreover, from the moment of the ignition, they offer their full potential.
Farewell to the past
Traditional halogen lights are outdated and energy-consuming, and xenon lighting does its job well; although they are already very exploited, they carry maintenance and it is expensive, added that they are not expected to evolve more.Therefore, as we have already seen, the LED collects all the advantages of xenon with a lower power consumption and allowing many more functions in favour of safety and aesthetics being also for life.
Lighting is no trivial matter and security either. The difference in the quality of vision of halogen headlights compared to some LEDs is very large, both by range and sharpness, as by visual fatigue when we take a couple of hours driving at night; a reason why they are ideal for who usually leads by roads with little illumination.
