What is the difference between having a lens and not having a lens?
1 Answers
The differences between car headlights with and without a lens are as follows: 1. Illumination distance: Headlights with a lens can refract light over a longer distance, and the lens adjusts the light distance according to the car's movement. 2. Light convergence: Headlights with a lens have better light convergence, making the light brighter. 3. Power consumption: Bulbs used with a lens have lower power consumption, which is beneficial for the electrical system. 4. Light scattering: In car headlights, the light pattern of a lens is the most standard, with a clear cut-off line between light and dark, solving the problem of light scattering.
