In fact, it can be seen from the new cars launched by major manufacturers that halogen lamps = low configuration, xenon lamps = mid-range configuration, and LED = high configuration. So, are halogen lamps really that bad? What are the advantages of xenon lamps and LEDs?
Advantages and Disadvantages of Halogen Car Lights
Halogen headlights are a new generation of incandescent lamps, tungsten lamps filled with halogen elements such as bromine and iodine or halide. After being energized, the electric energy heats the tungsten wire to an incandescent state and emits light. The electric energy is converted into heat energy and then into light energy.
advantage:
1. Low cost and simple production. 2. Low color temperature and good penetration. 3. Fast opening speed. 4. When encountering rain or fog, use a reflector for better penetration.
Disadvantages:
High temperature, poor durability and low brightness.
Xenon headlights advantages and disadvantages
The working principle of the xenon lamp (HID) is a high-pressure gas discharge lamp, which boosts the 12V voltage to an ultra-high voltage of 23,000V, stimulates the xenon filled in the quartz tube to make it emit light, and then converts the voltage to about 85V to provide stable and continuous supply. Xenon bulb glows.
advantage
1. High brightness: generally 3 times that of halogen lamps.
2. High color temperature: HID lamps can produce light with a color temperature of 4000-12000k, which is close to the color of midday sunlight and has the highest acceptance and comfort of the human eye.
3. Long life: a set of HID gas discharge lamps has about 3000 hours.
4. Low power consumption: The power of HID is generally only 35 W, while the power of ordinary car lights is generally 55 W.
5. It shows class and is generally only equipped in mid-to-high-end models. It enhances the symbol of status and face at night.
shortcoming
1. The heat is high, reaching 300-400 degrees, and the lampshade is easily burned.
2. There will be a delay
LED lights advantages and disadvantages
LED is the abbreviation of Light Emitting Diode, and its Chinese name is - light-emitting diode, PN junction. They now often appear as light boxes, signboards, and indicators and backlights for various electrical appliances. They are also often an important component of car taillights, high-mounted brake lights, and daytime running lights. LED headlights are lighting fixtures that use LEDs as light sources.
advantage
1. Long service life: LED components currently used in cars can basically reach at least 50,000 hours. 2. Good durability, not easy to break, good impact resistance and earthquake resistance. 3. Fast response. 4. High brightness.
shortcoming
Although it has been declining, the cost of LED is still high, so it generally only appears in mid-to-high-end models.
Analysis on the practical situation of halogen lamps, xenon lamps and LED lamps
Halogen lamp, strong penetrating power, 500 hours life;
Xenon lamps, the current mainstream, have good brightness but are not very stable. Now that the technology has matured, the stability is much better, but modifications usually require damage to the car body. The lifespan is 3,000 hours, and the cold light has weak penetrating power in rain and fog.
The new mainstream car lights are LED lights, which are energy-saving, bright enough, and have a long service life. They can generally reach 5,000 hours. The technology is stable and the installation is non-destructive.
In terms of cost performance, LED lights are the most practical.
Effect analysis (from best to worst):
HID modified original LED upgraded halogen lamp = replacement HID ordinary halogen lamp
In terms of effect, even the original LED is not as good as a good HID modification in terms of brightness alone. Of course, the intelligence of high-end original LEDs cannot be achieved by HID modification. The effect of upgraded halogen lamps will be better than most replacement HIDs and replacement LEDs, but it does not rule out that better replacement HIDs can surpass upgraded halogen lamps. The same is true for LEDs, but considering the car model adaptation, I put upgraded halogen The lights were at the front. Finally, let’s talk about an extreme situation. If you buy a bad replacement LED, the effect will be worse than ordinary halogen lamps. Don’t doubt it, there are many such products in the foreign trade market.
Economic analysis (from cheap to expensive):
Ordinary halogen lamp upgraded halogen lamp = replacement HIDHID modified original LED
There is nothing much to say about this. HID modification requires buying lenses, and xenon lamps also require longer modification work. Since the original LEDs are basically not made in China and even involve smart systems, the prices are not at the same level. Lifespan (from short to long) Upgraded halogen lamp Ordinary halogen lamp HID modified original LED Hey, a friend is missing? Or because the quality of replacement HIDs fluctuates so much, the lifespan is really hard to predict.
Ease of replacement (simple to complex)
Ordinary halogen lamp = upgraded halogen lamp replacement HIDHID modified original LED
The first two can be simply pulled out and replaced. The replacement HID requires a place to fix the ballast, but it is also within the scope of personal DIY. The latter two cannot be DIYed by yourself (except for hands-on emperors), because they will require professional equipment and knowledge.
Summarize
In fact, these three types of car lights have their own advantages and disadvantages, but we have to admit that with the reduction of costs, LED car lights will most likely become the mainstream in the future. The advantages of LED's service life and high brightness are very important to us. Very useful for daily use.
Although the status of the increasingly desolate halogen lamp has dropped significantly, its low cost and simple production characteristics still make it the first choice for many mid-to-low-end models.
After reading the editor's analysis above, you should have a certain understanding of the advantages and disadvantages of halogen lamps, xenon lamps, and LED lamps. You can choose according to your own usage.
