Which is better, LED headlights or xenon headlights?

With the rapid development of economy and technology, more and more people buy bicycles, but in the process of buying cars, many people are only concerned about the brand and performance of the car, but ignore a lot of details. For example, which kind of car lights should you choose? Is the choice of LED headlights good? Or choose xenon headlamps? Let's take a look at LED headlights and xenon headlights first.
The basic structure of the LED is an electroluminescent semiconductor material chip, solidified to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver or gold wire, and then sealed around with epoxy resin to protect the internal core wire, and finally installed the shell, so the seismic performance of the LED lamp is good. It is understood that LED, light-emitting diode, is a solid semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket, one end is a negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire chip is encapsulated by epoxy resin. A semiconductor chip consists of two parts, one is a P-type semiconductor, in which holes dominate, and the other is an N-type semiconductor, on which are mainly electrons. But when the two semiconductors are connected, a P-N junction is formed between them. When the current is applied to the chip through the wire, the electrons are pushed to the P region, where the electrons are combined with the holes, and then the energy is emitted in the form of photons, which is the principle of LED light. And the wavelength of light, the color of light, is determined by the material that forms the P-N junction.
Xenon lamp (HID) is a high pressure gas discharge lamp. Xenon lamp is a heavy metal lamp, by filling a variety of chemical gases in the anti-ultraviolet quartz glass tube, such as xenon and other inert gases, and then through the supercharger to the car 12 volts power supply instant to 23,000 volts, at high voltage, xenon will be ionized and produce a light source between the two poles of the power supply. The performance of xenon lamps has been significantly improved compared with halogen lamps, its luminous flux is more than 2 times that of halogen lamps, and the efficiency of converting electrical energy into light energy is also more than 70% higher than that of halogen lamps.
It is understood that the full name of xenon headlamp is HID (High Intensity Discharge Lamp) gas discharge lamp, which uses the matching electronic ballast to instantly increase the 12V voltage of the car battery to more than 23KV triggering voltage, the xenon in the xenon headlamp ionization arc discharge and make it stable and luminous. Provide stable automotive headlight lighting system. Xenon lamp broke the principle of tungsten filament luminescence invented by Edison, filled high pressure inert gas - Xenon Xenon in the quartz lamp tube, replacing the traditional filament, there are mercury and carbon compounds on the two electrodes, through the stabilizer with 23,000 volts high voltage current to stimulate xenon luminescence, forming a perfect white arc between the poles, the light emitted is close to the very perfect sunlight.
In this way, the two lights are very powerful high-tech products ah, then, the car taillights and headlights on the choice of what lights to achieve good lighting effects can also make the overall aesthetic effect?
In terms of shape, the most significant feature of LED lights as car lights is that they are actually composed of a large number, small size and high brightness of the lamp particles, which are generally combined into a certain shape, such as a light line or a large overall area. Xenon headlights as car lights located in which are generally relatively independent individuals, of course, there are some models are the use of bi-xenon headlights.
Of course, the most important thing about the lamp is to illuminate, and if the two lamps must be compared with each other, it must be that the LED lamp has an advantage in terms of luminous efficiency. However, the LED lighting is sufficient, and the lighting distance is relatively limited, generally less than 10 meters. And xenon headlights are also bright, but slightly less than LED headlights. But its own main role is used for lighting, the specific lighting distance is not statistics, but it is much farther than the traditional LED headlights.
Secondly, in terms of energy saving, in the use of the same power of LED lamps and xenon headlamps, LED luminous efficiency is higher, although its ability to withstand high temperatures is slightly weaker, the concentrating effect is also slightly worse than xenon headlamps. The advantages of LED itself being more energy efficient are indeed beyond doubt. Energy saving and environmental protection are the characteristics of LED lights.
