With the rapid economic development of technology, more and more people buy the rider, however in the purchase process, many people are only concerned about Guzhe car brands, and performance, and so on, but ignore many of the details. Such as automotive lamp should choose which one? Choose LED headlamps is good? Xenon headlamps or choose good? We might as well take a look at LED headlights and xenon headlamps it.
LED is the English light emitting diode (light emitting diode) abbreviation, and its basic structure is an electroluminescent semiconductor material chip, with a silver paste or white glue to solidify the bracket, then with silver or gold thread connecting the chip and the circuit board and then sealed with epoxy resin around, protect the internal core wire, the final installation of the housing, so the seismic performance LED lamps. It is understood, LED, light emitting diode, is a way to convert electrical energy into visible light solid-state semiconductor devices, which can be converted directly into electricity to light. LED heart is one end of a semiconductor wafer, the wafer is attached to a bracket, one end is negative, and the other end connected to the positive power supply, so that the whole chip is epoxy encapsulated. The semiconductor chip consists of two parts, part of P-type semiconductor, the hole in it dominates the other end of the N-type semiconductor, here is mainly electronic. But when the two semiconductor connected to form a P-N junction between them. When the current through the wire act on the chip, the electron will be pushed to P zone electron hole recombination, and then will emit energy in the P region in the form of photons, which is the LED light-emitting principle. The wavelength of light is the color of the light, it is formed by the material P-N junction decision.
The xenon lamp (HID) that is high-pressure gas discharge lamp. Xenon is a heavy metal lamp, by filling a variety of chemical gases within the UV crystal quartz glass tube, an inert gas such as xenon, and then through the booster car 12 volt power instantly increased to 23,000 volts, at a high voltage xenon It will be ionized and between the power poles to produce light. Performance than halogen xenon lamp has been significantly improved, and its luminous flux is more than 2 times the halogen lamp, electrical energy into light energy efficiency than halogen improved by more than 70%. It is understood, xenon headlights stands for HID (High Intensity Discharge Lamp) gas discharge lamp electronic ballast supporting the use of the car battery voltage is 12V to 23KV instant upgrade over the trigger voltage, the xenon headlights in xenon gas ionization an arc discharge and stabilize the light, to provide a stable vehicle headlamps lighting system. Xenon lamp broke Edison’s tungsten light principle, filled with high-pressure inert gas -Xenon xenon gas inside the quartz tube, replace the traditional filament, the two electrodes of mercury and carbon compounds, with 23,000-volt high-pressure through ballast current to stimulate the xenon light, form a perfect white arc between two poles, the light emitted close to perfect sunlight.
It would appear that two lights are very powerful high-tech products ah, then the car taillights and headlights that is exactly the choice of what lamp to achieve good lighting effects can make the overall aesthetic effect?
In terms of shape, LED lights car lights as the most significant feature is the fact, determined by the number, small size, high brightness lamp combination tablets are generally combined into a certain shape, such as a lamp or a large whole line area. And as the car lights xenon headlights which are generally located relatively independent of the individual, of course, there are also part of the model is the use of bi-xenon headlights.
Of course, the lights illuminate the most important thing, if you have to race with two lamps brightness LED lamp is certainly an advantage in luminous efficiency. But LED lights bright enough, lighting is relatively limited distance relative xenon headlights, a generally less than 10 meters. Xenon headlamps are also considered bright, but slightly inferior and LED headlamps. But its main role itself was originally used for lighting, in particular from the lighting, although not statistics, but than traditional LED headlamps much more.
Secondly, in energy efficiency, then, using the same power LED lights with Xenon lamp, LED high luminous efficiency of some, albeit weaker ability to withstand high temperatures, the effect is slightly worse than the condensing xenon headlamps. LED itself more energy-efficient advantages really in doubt. Energy saving and environmental protection has always been LED
Here, I believe we all know has a bottom of it, like the small size, but also want to play a series of reaction can select energy saving LED, like a whole, bright Cheng Yuan may wish to consider xenon headlights. But how to choose, in fact, still have to configure individual needs and based on specific models.
