With the advancement of technology, the changes of the lights are also very fast. From the halogen lamps used in the past to the current xenon lamps and more advanced LED lights, the development of the lamps is also a thousand miles. If you are not satisfied with the original car lights, it does not matter, many car owners in order to pursue brightness, safety, or just to make it more dazzling, to modify various lights. The lights are closely related to the safety of driving. If you just want to change the lights with a fun and cool attitude, you must not. Do not think that the lights can be changed at will, or the more expensive the more advanced the better, in fact, each car has its advantages and disadvantages, badly changed will only be counterproductive!
Halogen lamp:
Also known as tungsten halogen bulbs, quartz bulbs, is a variant of incandescent lamps. The principle is to inject halogen gas such as iodine or bromine into the bulb. At high temperature, the sublimated tungsten wire chemically reacts with the halogen, and the cooled tungsten re-solidifies on the tungsten wire to form a balanced cycle, avoiding the tungsten filament. Early break. Therefore, halogen lamps have a longer life than earlier incandescent lamps and are an improvement.
However, with the continuous evolution of the lights, the shortcomings of halogen lamps began to appear. Halogen lamps have poor illumination at night or in bad weather conditions, such as rain and fog, and even greatly reduce the driver's field of vision. This is mainly reflected in insufficient brightness. Therefore, many car owners will seek other lighting systems, such as xenon lights, LED lights, etc., which are currently the most popular car light conversion options.
Life expectancy: average 500 hours or more
Energy consumption: general halogen headlights 55w
Lighting effect: the light is even, but the brightness is relatively average, but the yellow headlight is very penetrating
Dressing suggestion: If the original lamp is a halogen lamp, it is not necessary to change it to an LED lamp. Nowadays, many international brands have introduced white-light upgraded halogen bulbs. These products have greatly improved color, brightness and life compared with ordinary halogen lamps. And more importantly, the price is much lower than the price of xenon lamps and LED lamps, and it is relatively more economical to replace when damage occurs. In addition, halogen lamps have the best penetration among the three lamps, so it is recommended to use traditional halogen lamps for the high beam regardless of other lamps.
Xenon lights
Referred to as HID xenon lamp, it can be called metal halide lamp or xenon lamp. Its light-emitting principle is to raise the voltage to more than 23000V through the starter and electronic ballast to break the helium gas, which causes the helium to form an arc between the two electrodes. And shine. Therefore, if you look closely, you will find that there is no filament in the HID xenon lamp head, but the current generated between the electrodes is used to cause the collision of the helium molecules to produce brightness, and there is no problem that the tungsten wire is blown.
The xenon lamp requires only 3.5A of current, and its brightness is three times that of a conventional halogen bulb. Its lifetime is 10 times longer than that of a conventional halogen bulb. Due to the high brightness, it is possible to provide a wider, brighter, longer distance illumination. Moreover, the xenon lamp will not be extinguished instantaneously, but will gradually darken until it is extinguished, so it will not suddenly extinguish when it encounters a lamp failure, which increases safety and wins emergency treatment time for the owner.
However, Xenon lamps also have obvious shortcomings. The biggest disadvantage is that the penetration rate is low. When it encounters rain and fog, it is more disadvantageous; and it takes 2 to 3 seconds to reach the full bright spot. Therefore, it is generally not recommended to replace the high beam with a xenon lamp. However, there are exceptions. Some xenon lamps have a yellowish color temperature and are relatively transparent. The price of xenon lamps is also more expensive than halogen lamps.
Life expectancy: up to 30,000 hours, which is 6 times the life of a typical halogen bulb
Energy consumption: conventional xenon headlights 35w
Lighting effect: relative light concentration, high brightness
Dressing recommendations: Xenon lamps have high brightness and are relatively cheaper than LEDs. However, xenon lamps also have the disadvantage of not being able to reach the brightest at the moment, and the penetration is low. Therefore, the general recommendation is that the headlights can be converted into xenon lamps.
LED light
An LED lamp is a solid-state semiconductor device that converts electrical energy into visible light, which directly converts electricity into light. Significantly different from halogen lamps and xenon lamps, LED lamps are made up of a large number of small, high-density lamp pellets, so they can be easily designed into various shapes and look more beautiful.
The LED lamp is currently the most energy-efficient, but it is a cold light, its ability to withstand high temperatures is slightly weaker, and the concentrating effect is slightly worse than that of xenon headlights. LED lights have the most advantages in terms of brightness, they are brighter than xenon lamps, and they can be turned on instantly. However, LED lights are lacking in illumination distance and have poor penetrability, so they are generally not used in headlights. However, this phenomenon has now been broken. Under the advancement of technology, the headlights of many models have adopted LED headlights. In addition, the operating temperature of LED lamps is very low, so there is a problem of heat dissipation - if the heat is not good, the life will be greatly shortened.
Life expectancy: up to 100,000 hours
Energy consumption: energy consumption is only 1/20 of halogen lamp
Lighting effect: The spectrum is almost entirely concentrated in visible light, the luminosity is very high, and the brightness is highest in xenon lamps and halogen lamps.
Dressing suggestions: The advantages of LED are obvious. It can reach the brightest, energy-saving and highest brightness in an instant, and there are many beautiful designs, which are the most beautiful and beautiful. But if you want to convert into LED lights, the first thing to consider is the cost. Due to the more advanced technology of LED lights, the maintenance cost is also high. Moreover, if many LED models are broken, it is necessary to replace the entire lamp assembly. The price is at least several thousand yuan.
