The Function of Optical Lens and the Law of Imaging
Release time:
2024-04-11 11:28
The function and imaging law of optical lens. The lens is an optical element made of transparent material, and its surface is a part of spherical surface. The lens consists of several lenses. There are two kinds of plastic lenses and glass lenses. The lens is made of a transparent material. Made of optical elements that affect the curvature of the light wavefront. It is a device that can converge or disperse light, and the resulting image has real and virtual images.
the role of optical lens:
The lens can be widely used in various fields such as safety, car wear, digital cameras, lasers, and optical instruments. With the continuous development of the market, lens technology is more and more widely used. Lenses are made according to the law of refraction of light. A lens is an optical element made of a transparent material (e. g., glass, crystal, etc.).
The role of lens in car lighting:
Because the lens has a strong light gathering ability, it can be used to illuminate the road, not only the road is bright, but also clear.
Because the dispersion of light 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 intersections or missing targets.
Compared with headlights with traditional lamp holders, headlights with lens-type lamp holders have uniform brightness and strong penetrating power, so their penetrating power is stronger regardless of rain or fog. In this way, oncoming vehicles can immediately receive light information, thereby avoiding accidents.
The life of the HID bulb in the lens is 8 to 10 times that of ordinary bulbs, to reduce unnecessary trouble, you don't have to always replace the bulb.
The lens xenon lamp does not need to install any power supply system, because the real HID gas discharge lamp needs a voltage stabilizer, 12V voltage, and then converts the voltage to normal voltage, and can stably and continuously provide the xenon lamp, so as to achieve the power saving function.
