Who said that? What are the advantages and disadvantages of dual optical lenses?

Advantages: the change and use of automobile lighting effect are realized, and the convenience and convenience of driving at night are improved.

Disadvantages: the price is more expensive.

Halogen bulbs or xenon bulbs are generally used for single lenses. In a single lens, there are lenses corresponding to the low beam and the high beam respectively. The difference between the two lenses is that it can make a transformation similar to the transformation between the high beam and the low beam, usually in the low beam state.

The dual lens can switch between far and near light through the shading sheet inside the lens. When the shutter is closed, it is low beam, and when the shutter is opened, it is high light! But the light bulb in the lens is motionless and unchanged.

Extended data

1, because the lens has strong light gathering ability, it is used to illuminate the road, which is not only bright but also clear.

2. Because the light dispersion is very small, its light range is farther and clearer than that of ordinary halogen lamps. Therefore, you can see things in the distance for the first time and avoid crossing or missing the target.

3. Compared with the headlight with traditional lamp cap, the headlight with lens lamp cap has uniform brightness and strong penetration, so it has strong penetration in rainy and foggy days. So that oncoming vehicles can receive lighting information at the first time to avoid accidents.

4. The life of the HID bulb in the lens is 8 to 10 times longer than that of the ordinary bulb, which reduces the unnecessary trouble caused by changing the lamp all the time.

5. The lens hernia lamp does not need to be equipped with any power supply system, because the real HID gas discharge lamp only needs a voltage regulator with a voltage of 12V, and then the voltage is converted into a normal voltage, which can be stably and continuously supplied to the xenon bulb to emit light, thus achieving the purpose of saving electricity. .
