AI Technical Summary
Technical Problem
Existing zoom illumination modules have a large number of lens groups and a large size. After multiple refractions/reflections, the effective illumination intensity decreases, affecting focusing and image quality.
Method used
By employing a first lens with negative optical power and a second lens with positive optical power, and using a driving device to move the second lens between the first lens and the light source, the light beam can be converged or diverged. This reduces the number of lens groups and the number of light refractions.
Benefits of technology
The lighting module is miniaturized and lightweight, while ensuring effective lighting intensity, reducing light loss, and improving image quality.
