“My car headlight is a halogen lamp. I wonder if it can be changed to an LED or xenon lamp. Will it affect future use or annual inspection of motor vehicles after replacement?”
The reporter interviewed the car modification division and hoped to provide some references to consumers who wanted to modify the headlights.
LED need to install a lens higher cost
“The original car halogen lamp into LED lights, the need to improve the entire vehicle lamp system.” Xi’an Leica car modification company, Xu Zhi said that LED installation is not standardized will appear to light up and overheat, resulting in attenuation or even abruptly extinguished the brightness of the market’s LED Product quality is uneven, and failures often require high repair rates.
Once the original halogen lamp is changed to LED, the luminous point will change, depending on whether the original lamp is equipped with a lens. If the original lamp lens or reflective bowl is not changed, the illumination range and angle will change, and the effect of the lamp illumination will be deteriorated. LED color temperature is relatively high, high brightness, high lumens, but the irradiation distance is short. Look outside the car is very bright, but found a short distance after boarding.
On the market, cheap LED quality is generally good, and the price of good quality is too high. It is difficult for the general consumer to accept a million dollars to change the lights. Moreover, there are many faults in the conversion of LED lights. If the far and near lights are not equipped with a lens, after installing the LED, it will cause significant astigmatism and serious flares, affecting night driving.
Halogen-modified xenon lamp recommended to be replaced together with the lens
According to Xu Zhi introduction, the car headlight conversion upgrade xenon lamp is the first choice for many riders. Illuminating a xenon lamp requires a starting voltage of 23,000 volts, whereas a conventional automotive halogen lamp requires only 12 volts of operating voltage. The bi-optical lenses of halogen lamps cannot be directly replaced by xenon lamps. Xenon lamps are illuminated by high-voltage arc discharge and require an additional electronically controlled starting device outside the bulb, commonly known as a ballast.
The ballast is a separate component outside the bulb. The quality of the ballast will directly affect the lifespan of the entire lighting system. Xu Zhi said that poor quality ballasts will produce strong electromagnetic interference during work and affect the radio work inside the car. Xenon bulbs are rarely bad, but because they are filled with high-pressure helium gas up to 6 atmospheres and a certain amount of mercury and metal halides, if it bursts or leaks, it not only pollutes the environment, but it can also hurt people and hurt the car.
In the conversion of xenon bulbs, the corresponding lamps should also be replaced. Due to the curved shape, the focus position of the original halogen lamp does not fully adapt to the arc of the xenon lamp. If the original car is a halogen lens, it is recommended to replace the lens together. Halogen light is a linear light source, and xenon light is a point light source. The focal point of the lens is not the same from the design. If the light bulb is replaced directly, the light type is not correct and the effect cannot be achieved. If the car changes the lamp, the headlight power should not exceed 50 watts, which means that the bulb plus the transformer should not exceed 50 watts, otherwise it is very likely that the circuit will burn.
Annual test light intensity, High color temperature lights cannot pass
Tian Lei, a Xi’an Foreign Motor Vehicle Inspection Station, said that the annual inspection of automotive lights is based on the intensity of light. The motor vehicle’s light must pass 1050 lumens in the near-light, and the high beam can pass the test more than 1,450 lumens. Under normal circumstances, the original car halogen lamp converted into xenon lamp, as long as the addition of bifocal lenses, can not detect the problem of astigmatism, can pass the annual inspection.
At the vehicle inspection station, the lights are damaged, the brightness is too low or too high, and they cannot pass the test. Some car lights have not reached the standard, mainly due to the high color temperature of the lights.
Vehicles with heavy lighting modification and malicious construction will cause the car to pass the annual inspection. Such as: 1 modified HID xenon lamp with high color temperature, will have a major impact on the other party when the car lights. 2 Some lights with astigmatism are too severe. 3 After the xenon lamp was changed, the angle of light irradiation exceeded the standard, and the detection line could not be passed. If you just upgrade the light level without causing light pollution, you can pass it.
