AI Technical Summary
Technical Problem
Existing strip or line-shaped vehicle lights have complex optical systems and low luminous efficiency, which affects the brightness of the lights.
Method used
The high-beam optical module includes a light source, a first lens, and a second lens. The first lens is a convex lens, and the second lens is located at or between the focal point of the first lens and the focal point. The light rays are converged by the first lens and then emitted as parallel light through the second lens, thus achieving beam contraction of the light rays perpendicular to the light output direction.
Benefits of technology
It forms a narrow light spot, improves light efficiency and brightness, has a compact structure, low cost, and is suitable for strip or line-shaped vehicle headlight designs.

Abstract
The high-beam optical module comprises a light source, a first lens and a second lens, the first lens and the second lens are sequentially arranged in the transmission direction of a light path, the first lens is a convex lens, the focus of the first lens coincides with the focus of the second lens, or the focus of the second lens coincides with the focus of the first lens. The second lens is located between the focal point of the first lens and the first lens; light emitted by the light source sequentially passes through the first lens and the second lens, and then beam shrinkage of the light is achieved in the first direction perpendicular to the light emitting direction. The light rays are emitted after being subjected to beam shrinkage, and the emitted light rays have the characteristics of high light efficiency and high brightness; and beam shrinkage is achieved through cooperation of the first lens and the second lens, the size of the second lens is small, and therefore the high beam optical module is compact in overall structure and low in cost.
