There is a halogen bulb inside the LED bifocal lens. A bifocal lens is a lens. Through the light shield inside the lens, you can switch between high and low light. When the light shield is closed, it is low beam. When the light shield is open, it is high beam, but the light bulb inside the lens does not move. , there is no change.
Application of bifocal lenses
Bifocal lenses are mostly used for near and far beams. Xenon headlights use one light source. There is a light shield inside the lens. The far and near beams are This is achieved by moving the light shield up and down. In this way, only one xenon bulb is needed to switch between near and high beams. The development and application of this technology enables the change and use of car lighting effects, improving the convenience and convenience of driving at night.
The 3D lens is a super-cool daytime running light during the day. When the car is parked and the key is turned off, it can continue to light up for a period of time. It not only lights up the way home, but also leaves enough time for the audience. Stop and admire. Zhongshan Yiben's 3D lens is a first-of-its-kind invention patented product that cleverly applies product engineering design principles, organically integrates broad cultural and artistic connotations, and is close to people's lives.
