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
shortcoming:
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 lasts about 3,000 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. 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, cold light, and weak penetration in rainy and foggy days;
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.
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.
