Halogen lamp, xenon lamp, LED lamp, which one of them is practical, you will know after reading it. When buying a car, some people can easily ignore the choice of car lights. In fact, car lights are equivalent to car eyes and can be clear in the dark. Looking at the road ahead, ordinary cars have halogen lamps, xenon lamps and LED lamps. In fact, the cars produced by manufacturers are easy to find. Low-profile cars use halogen lamps, and xenon lamps are used inside. LED lights, halogen lights are the lowest lights? Xenon lamps and LED lights are good.

First, explain the halogen lamp. The halogen lamp is the next generation of incandescent lamps. Tungsten lamps containing halogen elements such as bromine and iodine and halides. After being energized, the tungsten filaments are heated to incandescent heat with electric energy and emit light. The principle is that electric energy is converted Heat energy is converted into light energy. Its advantages are 1. Low cost, simple manufacturing process, 2. Low color temperature, good air permeability, 3. Fast opening speed, disadvantages are high temperature, poor durability, and low brightness.

Please talk about the xenon lamp again. The working principle of the xenon lamp is to use high-pressure gas discharge, especially by boosting the 12V voltage to an ultra-high voltage of 2300V, pressurizing the xenon gas filled in the quartz tube to make it glow, and then converting the voltage to 85V Right and left, continue to supply energy to the xenon lamp, do you think it is very high? Its advantages are high brightness, 3 times that of halogen lamps, 2. High color, suitable for human eye acceptance and comfort, 3. Long life span, about 3000 hours, but the disadvantages are delay, high heating temperature, reaching 340 Baidu, the lampshade is easy to burn.

The last thing I want to talk about is LED lights. LED is the acronym for the English word LightEmittingDiode, which means light-emitting diode in Chinese. I think many of my friends know this new technology, whether it is desk lamps or chargers, shop signs, car tail lights All lamps made of this material are used. LED lamps are lighting appliances made with light-emitting diodes as the light source. Its advantages are 1. Long service life, basically reaching 50,000 hours, 2. Durable signal, not easy to damage, impact resistance And good shock resistance, 3. Very fast response time, 4. High brightness, the disadvantage is high cost.

In terms of cost performance, LED lamps are the most practical. In terms of economy, ordinary halogen lamps lt; upgraded halogen lamps lt; xenon lamps lt; LED lamps. In fact, these three lamps have advantages and disadvantages, depending on the preference of friends Very important, but with the development of technology, the popularization of LED lights will become the mainstream in the future.
