A lens is an optical element that can be made from a material of a specified spectrum. Generally, optical glass is used in the visible and near-infrared spectra (IR-A nm)(400-1400nm), and crystal materials are used in the mid-infrared (IR-C nm)(3-50mm). In today's era of continuous development, optical lenses have also begun to be used everywhere, integrated into every corner of our lives, and our lives have been inseparable. Optical lenses are often used in our lamps, so optical lenses are used in car lights. What are the roles?
What are the roles of optical lenses in car lights:
1. Because the lens has a strong light gathering ability, it is used to illuminate the road, not only the road is bright, but also clear.
2. Because the light dispersion is very small, its light range is farther and clearer than ordinary halogen lamps. Therefore, you can immediately see things in the distance and avoid crossing the intersection or missing the target.
3. Compared with the traditional lamp holder, the headlight of the lens lamp holder has uniform brightness and strong penetrating power, whether it is rainy or foggy. Therefore, oncoming vehicles can immediately receive lighting information to avoid accidents.
The life of the HID bulb in the lens is 8 to 10 times that of the ordinary bulb, reducing the unnecessary trouble that you always change the lamp.
5. The lens xenon lamp does not need to install any power supply system, because the real HID gas discharge lamp needs a voltage stabilizer and 12V voltage, and then the voltage is converted into normal voltage to stably and continuously supply the xenon bulb to emit light. This can save energy.
6. Since the lens bulb is boosted from the stabilizer to 23000V, the xenon gas is stimulated to reach a high brightness when the power is turned on for the first time, so the brightness is maintained for 3-4 seconds when the power is off. This allows you to prepare for parking in advance in an emergency and avoid disasters, which traditional halogen lamps cannot do.
The above content is the introduction of the role of optical lens in car lights. Optical lens is an optical element made of transparent material. Optical lens is a refractor with two balls or a ball and a plane transparent body. Its image includes images and virtual images. With the continuous development of the market, optical lens technology is more and more widely used, which can be widely used in security, automotive, digital cameras, lasers, optical instruments and other fields.
