Which Is Better, LED Car Lights or Xenon Headlights?

With the rapid development of economy and technology, more and more people are buying cars. However, in the process of buying cars, many people only pay attention to the brand and performance of the car, but ignore many details. For example, which kind of car light should I choose? Is it better to choose LED headlights? Is it better to choose xenon headlights? Why not take a look at LED headlights and Xenon Headlights first.

The basic structure of the LED is a chip of electroluminescent semiconductor material, which is cured on the bracket with silver glue or white glue, and then the chip and the circuit board are connected with silver or gold wire, and then sealed with epoxy resin to protect the inside. The role of the core wire is to install the shell at last, so the Car Led Headlights has good seismic performance. It is understood that LED, light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a support, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. The semiconductor wafer is composed of two parts, one part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, where electrons are mainly used. But when these two semiconductors are connected, a P-N junction is formed between them. When the current acts on the chip through the wire, the electrons will be pushed to the P area, where the electrons and holes recombine, and then emit energy in the form of photons, which is the principle of LED light emission. The wavelength of light is the color of light, which is determined by the material forming the P-N junction.

The xenon lamp is a high-pressure gas discharge lamp. The xenon lamp is a heavy metal lamp. By filling a variety of chemical gases, such as xenon and other inert gases, into the UV-resistant crystal quartz glass tube, and then using a supercharger to instantly increase the 12 volt power supply to 23000 volts, under 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 twice that of halogen lamps, and the efficiency of converting electrical energy into light energy is also increased by more than 70% compared with halogen lamps. It is understood that the full name of the xenon headlamp is the HID gas discharge lamp. It uses a supporting electronic ballast to instantly increase the 12V voltage of the car battery to a trigger voltage above 23KV, and ionize the xenon in the xenon headlamp to form an arc discharge and make it Stable light and provide a stable car headlight lighting system. The xenon lamp breaks the tungsten filament luminescence principle invented by Edison. The quartz tube is filled with high-pressure inert gas—Xenon xenon gas, instead of the traditional filament. There are mercury and carbon compounds on the two electrodes, and the high voltage is 23000 volts through the ballast. The electric current stimulates the xenon gas to emit light, forming a perfect white arc between the two poles, and the light emitted is close to perfect sunlight.

In this way, the two lamps are both very powerful high-tech products. So, what kind of lamp should be selected for the taillights and headlights of automobiles to achieve good lighting effects and make the overall aesthetic effect?

In terms of shape, one of the most notable features of LED lights as car lights is that they are actually composed of a large number, small size, and high brightness lamp particles, which are generally combined into a certain shape, such as a light line or a large whole. Area. The xenon headlights are generally relatively independent individuals as car lights. Of course, there are also bi-xenon headlights used in some models.

Of course, the most important thing for the lamp is to illuminate. If the brightness of these two lamps must be compared, it is definitely that the LED lamp has an advantage in luminous efficiency. However, the brightness of the LED lamp is sufficient, but the lighting distance is relatively limited compared to the xenon headlight, generally less than 10 meters. The xenon headlights are also bright, but slightly inferior to the LED headlights. But its main function is originally used for lighting. Although the specific lighting distance is not counted, it is much farther than traditional LED headlights.

Secondly, in terms of energy saving, under the same power LED lamp and xenon headlights, the LED luminous efficiency is higher, although its ability to withstand high temperatures is slightly weaker, the light-gathering effect is slightly worse than that of xenon headlights. The advantages of LEDs that are more energy efficient are indeed undoubted. Energy saving and environmental protection are originally the characteristics of LED lights.

Having said that, I believe everyone has a bottom line. Those who like small size, have a series of responses and want to save energy and environmental protection can choose LED, and those who like a whole, bright range may wish to consider xenon headlights. However, how to choose depends on the specific configuration of the model and personal needs.
